2Storage and transport conditionsSafety Notes

2.10 Storage and transport conditionsThe gear units can be provided with the following protection and packaging types de-pending on the storage and transportation conditions.

2.10.1 Internal corrosion protectionStandard corrosion protection

After the test run, the test oil fill is drained out of the gear unit. The remaining oil film pro-tects the gear unit against corrosion for a limited period of time.

Long-term corrosion protection:

After the test run, the test oil fill is drained out of the gear unit and the interior space isfilled will a vapor phase inhibitor. The breather filter is replaced by a screw plug and en-closed with the gear unit.

2.10.2 Exterior corrosion protectionThe following measures are generally taken for exterior corrosion protection:

• Corrosion protection is applied to bare, non-painted functional surfaces of shafts,flanges, mounting and foot surfaces on the gear unit. Remove it only using anappropriate solvent which is not harmful to the oil seal.

• Small spare parts and loose pieces, such as bolts, nuts, etc., are packed in corrosionprotection plastic bags (VCI corrosion protection bags).

• Threaded holes and blind holes are covered by plastic plugs.

2.10.3 PackagingStandard packaging

The gear unit is delivered on a pallet without cover.

Application: Land transport

Long-term packaging

The gear unit is delivered in a wooden box that is also appropriate for sea transport.

Application: Sea transport and/or for long-term storage

TIP• If the gear unit elevator drive is stored longer than six months, you must check the

protective coating of unpainted areas as well as the paint coating regularly. Areas with protective coating and/or paint that has been removed may have to be repainted.

3 Pivoted mounting positions and variable mounting positionsBasic Gear Unit Structure

3.7 Pivoted mounting positions and variable mounting positionsMounting positions differing from standard mounting positions are referred to as pivotedor variable mounting positions.

Gear units with pivoted mounting position have a fixed mounting position that differsfrom the standard.

Gear units with variable mounting position can change the mounting position variablywithin the specified range.

The designation of pivoted and variable mounting positions is set up as follows:

All final positions have to be specified if the mounting position of the gear unit deviatesfrom standard mounting positions in several directions. Combinations of fixed and vari-able final positions are possible.

Example of a gear unit that – based on M1 – is tilted by ±20° around the drive shaft dur-ing operation and is mounted in a fixed 30° angle around the longitudinal axis:

M1 – M2/20°/V – M4/20°/V – M5/30°/F

NOTICEDue to the rigid connection between the machine shaft and hollow shaft of the gear unit,constraining forces can occur on the output shaft bearing. This may result in damagesto the output shaft bearing and increased fretting corrosion in the connection betweenthe machine and the hollow shaft of the gear unit.

Possible damage to property! • The gear unit is usually foot or flange-mounted and used as bearing point when the

machine shaft has no individual bearing or merely provides one bearing point. You have to provide for an accurate coaxial alignment with the bearing point.

• If the machine shaft has at least two bearing points, the gear unit should be connected merely to the machine shaft and supported with a torque arm. Avoid foot or flange-mounted gear units in order not to overdimension the bearing.

3 Sealing systemsBasic Gear Unit Structure

3.12.4 Drywell sealing system

In addition to the usual sealing, vertical gear units with output shaft pointing downwardsmay be equipped with a Drywell sealing system. The lower bearing of the output shaftis separated from the oil chamber via an integrated tube [1]. The bearing is grease-lu-bricated and has to be relubricated in regular intervals (DIN 3404 A G1/8 flat grease nip-ple). The oil level is lower than the upper end of the tube, thus no oil [2] can leak outthere. In order to ensure a sufficient lubrication of the upper bearing and the gearing,each gear unit is equipped with a Drywell sealing system with pressure lubrication (shaftend pump or motor pump).

9007199961031563

[1]

[2]

TIPThe Drywell sealing system requires a dust-proof sealing system on the output shaft.

For gear units from size 220, the Drywell sealing system is possible only in combinationwith a standard bearing on the output shaft.

Due to the lowered oil level, the gear unit might have to be equipped with an additionaloil tank.

This depends on the following factors:• Gear unit size, gear ratio• Input speed, input power• Pump size, pump capacity• Ambient temperature during startupConsult SEW-EURODRIVE for further details.

3 LubricationBasic Gear Unit Structure

3.14 Lubrication3.14.1 Lubrication typesSplash lubrication The oil level is low; gearing and bearing parts that are not immersed in the oil bath are

lubricated by splashing oil. Standard lubrication type for horizontal mounting positions(M1 or M3).

Bath lubrication The gear unit is (almost) completely filled with oil; all gearing and bearing positions areeither completely or partly submerged in the oil bath.

• Standard lubrication type with oil expansion tank for:

• Swiveling mounting positions with horizontal gear units beyond a certaininclination angle (depending on type of gear unit, version and size)

• Vertical gear units (mounting position M5)

• Upright mounting position (M4) with X.K gear units

• Standard lubrication type without oil expansion tank for:

• Upright mounting position (M4) with X.F / X.T.. gear units

Pressure lubrica-tion

The gear unit is equipped with a pump (shaft end pump or motor pump). The oil level islow and may even be reduced when compared to splash lubrication. The gearing andbearing parts that are not immersed in the oil bath are lubricated by oil through lubrica-tion lines.

Pressure lubrication is used when:

• Splash lubrication is not possible (see the relevant mounting positions and variantsunder "Bath lubrication"),

• Instead of bath lubrication if it is not desired and/or is not thermally advantageous,

• Drywell sealing system is desired (only vertical LSS downwards),

• High input speeds are present and the speed limit for the other types of lubrication isexceeded (dependant on the gear unit size, version, and number of stages),

Shaft end pump A shaft end pump (direction-independent) supplies all bearing points and gearing out-side the oil sump with oil via a tube system.

The pump is mounted externally to the gear unit and is driven by the input shaft or inter-mediate shaft of the gear unit. A high reliability of the pump function is ensured in thisway.

The shaft end pump can be provided with 4 different flow rates. The adequate pump sizedepends on the following factors:

• Oil quantity required to supply the lubrication points

• Pump position (connected to input shaft or intermediate shaft)

• Gear unit reduction ratio

• Speed range of the gear unit

4Backstop /BSDesign of Options and Accessories

4.3 Backstop /BSThe purpose of a backstop is to prevent undesirable reverse rotation. During operation,the backstop permits rotation in one specified direction of rotation only.

The backstop functions by using centrifugal lift-off sprags. Once the lift-off speed isreached, the sprags completely lift off from the contact surface of the outer ring. Thebackstop is lubricated with gear oil.

The direction of rotation is determined with a view to the output shaft (LSS).

• CW = Clockwise

• CCW = Counterclockwise

The permitted direction of rotation [1] is indicated on the housing.

When operated below the lift-off speed, wear can occur in the backstop.

Consult SEW-EURODRIVE for defining the maintenance intervals for:

• Input speed rates n1 < 1000 rpm

• Design X4K180-250 i ≥ 200

6.7 Installing the gear unit

6.7.1 foundationTo ensure quick and successful mounting, the type of foundation should be correctly se-lected and the mounting carefully planned in advance. Foundation drawings with all nec-essary construction and dimension details should be available.

To avoid harmful vibrations and oscillations, adequate rigidity must be ensured whenmounting the gear unit on a steel construction. The foundation must be dimensioned ac-cording to weight and torque of the gear unit by taking into account the forces acting onthe gear unit.

Tighten retaining screws or nuts to the specified torque. Use the screws and tighteningtorques specified in section 6.3 "Gear unit mounting".

6.7.2 Aligning the shaft axis

The service life of the shafts, bearings and couplings depends on the precision of thealignment of the shaft axes with each other.

Always try to achieve zero deviation. When doing so, you should also consult the specialoperating instructions regarding the requirements of the couplings, for example.

NOTE ON EXPLOSION PROTECTIONProcesses that cause strong electrical charge due to fast moving particles on the coat-ing must be excluded (e.g. due to fluid liquids and solids)!

NOTICEAn improper foundation may result in damages to the gear unit.

Possible damage to property!• The foundation must be level and flat, the gear unit may not be deformed when the

retaining screws are tightened. Unevenness must be leveled out appropriately.

DANGER

Shafts may break if shaft axes are not aligned exactly.

Severe or fatal injuries.• Refer to the separate operation instructions regarding the requirements of the

• Carry out the oil filling process with the gear unit in the intended mounting position.

• Make sure that the oil has room temperature for the filling process.

• For gear units with external supply pipes, e.g oil/air cooler, establish the connectionsprior to the filling process.

• Observe the additional notes depending on the lubrication type in the following sec-tions.

6.10.1 Gear units with splash lubrication or bath lubrication without oil expansion tankNote the following:

• The oil type and oil quantity must correspond to the nameplate data and theinformation given in section 8.6 "Changing the oil".

• Check the oil level via the oil level glass, the oil dipstick or the oil sight glass. Referto section 8.5 "Checking the oil level".

DANGER

Risk of crushing if the drive starts up unintentionally.

Severe or fatal injuries.• De-energize the motor before you start working on the unit.• Secure the motor against unintended power-up.

NOTICEImproper oil filling may result in damages to the gear unit.

Possible damage to property!• Note the following:

NOTE ON EXPLOSION PROTECTION• The plugs for checking and draining oil and the breather valves must be freely

accessible.• Check the correct oil fill specified for the relevant mounting position prior to startup.

6.10.2 Gear units with bath lubrication and oil expansion tank

Proceed as follows:

1. Open all upper screw plugs [1] of the gear unit. In some designs, the breather pipe[4] is equipped with a T piece [7]. In this case, open the screw plug [6] of the T-piece[7] as well.

2. The type and quantity of oil is stated on the nameplate.

NOTE ON EXPLOSION PROTECTIONInadequate filling may result in a damage to the upper bearing due to insufficient lubri-cation.

Possible damage to property!• Perform the oil filling process for gear units with oil expansion tank with utmost

caution.

TIPPrior to the filling process, make sure that the breather pipe [4] between bearing pointsand oil expansion tank are not blocked.

This is the only way to ensure a flawless venting of the bearing points.

3. Fill in the oil via the oil filling hole [2] or via one of the screw plug holes [1]. Whenfilling via the oil filling hole [2], make sure that the oil level stays below the connectionfor the breather pipe [4] at the oil expansion tank [5] so that it is not clogged!

4. As soon as the oil reaches the holes of the screw plugs [1], screw the respectivescrew plug back into the housing. This is how you prevent air pockets.

5. For designs equipped with a T-piece [7] in the breather pipe [4] fill in the oil until thereis oil leaking from the T-piece [7]. This is when the gear unit is completely filled withoil. Reinsert the screw plugs [6] of the T-piece [7].

6. Check the oil level via the oil dipstick [3].

7. Due to air pockets in the gear unit, the oil level may drop after the filling process. Thisis why you should check whether the oil level drops regularly during the first few op-erating hours. Check the oil level after the gear unit has cooled down to the ambienttemperature.

6.10.3 Gear units with pressure lubrication

Note the following:

• The oil type and oil quantity must correspond to the nameplate data and theinformation given in section 8.6 "Changing the oil".

• Check the oil level at the oil level glass, oil dipstick or oil sight glass. See section 8.5for more information.

• If the pump is installed above the oil level, the pump might not suck and thus the gearunit would not be lubricated sufficiently. If this is the case, fill the shaft end pump viathe screw plug [1]. Fill the pump just before startup.

Connecting the pressure switch

All gear units with pressure lubrication are equipped with a pressure switch for functionmonitoring.

The pressure switch is to be connected and integrate into the system so that the gearunit can only be operated with the oil pump building up pressure. A short-term compen-sation (max 10 sec.) during startup is permitted. Observe section 4.14 "Pressureswitch".

The following table shows various methods for measuring the differing tolerances.

Measuring instruments

Angular offset Axis offset

Feeler gauge

This method only achieves an accurate result when the deviation of the coupling faces is eliminated by turning both coupling halves by 180° and then calculating the average value from the difference (a1 – a2).

The following illustration shows the measurement of axial mis-alignment using a straight-edge. Permissible values for eccentric-ity are usually so small that the best measurement results can be achieved with a micrometer dial. If you rotate one coupling half together with the micrometer dial and divide the deviation by two, the deviation displayed on the micrometer dial indicates the mis-alignment (dimension "b") that includes the axial misalignment of the other coupling half.

Micrometer dial

A prerequisite for this measuring method is that there is no axial play in the shaft bearings when the shafts rotate. If this condition is not fulfilled, the axial play between the faces of the coupling halves must be eliminated. As an alternative, you can use two micrometer dials positioned on the opposite sides of the coupling (to calculate the dif-ference of the two micrometer dials when rotating the coupling).

The following figure shows the how to measure axial misalign-ment using a more accurate measuring method, as described above. The coupling halves are rotated together without letting the point of the micrometer dial slide onto the measuring surface. The axial misalignment is obtained by dividing the deviation displayed on the micrometer dial (dimension "b").

Cleaning and lubri-cating the shrink disk

Before re-assembly, you have to clean and lubricate the shrink disk.

1. Thoroughly clean the shrink disk from dirt and any remaining lubricants after disas-sembly.

2. Lubricate the retaining screws [10] on the threads and under the head with an MoS2compound, e.g. "gleitmo 100" from FUCHS LUBRITECH (www.fuchs-lubritech.com).

3. Also evenly lubricate the tapered surface of the taper (outer ring) [9a] with a thin layerof an MoS2 compound, e.g. "gleitmo 100" from FUCHS LUBRITECH (www.fuchs-lu-britech.com).

TIP• You must perform the following steps carefully in order to ensure that the shrink

disk functions perfectly. Use only products that are comparable to the lubricant that is given.

• If the tapered surfaces of the shrink disk are damaged, the shrink disk can no longer be used and must be replaced.

7.9 Gear unit shutdown/conservation

Additional conservation measures are required if the gear unit is to be shut-down for alonger period. Depending on the location, the ambient conditions, and the lubricationstate, even a few weeks of downtime might require conservation measures.

7.9.1 Internal conservation

• New or hardly used gear units:

• For internal conservation, SEW-EURODRIVE recommends the VCIconservation method.

• Apply the required amount of VCI anti-corrosion agent to the inside of the gearunit (e.g. FUCHS LUBRITECH Anticorit VCI UNI IP-40, www.fuchs-lubritech.com). The amount depends on the free space inside the gear unit.Usually any existing oil may remain in the drive.

• Replace the breather filter with a screw plug and close the gear unit so that itis air tight. Prior to startup, re-install the breather filter.

• After longer use:

• As, after longer operating periods, the oil might be contaminated (oil sludge,water, ...), drain the oil and thoroughly rinse the inside of the gear unit with newoil prior to conservation. Observe the information in section "Changing the oil"in the corresponding operating instructions. Then the inside of the gear unitmay be conserved as described above.

DANGERRisk of crushing if the drive starts up unintentionally.

Severe or fatal injuries.• De-energize the motor before you start working on the unit.• Secure the motor against unintended power-up.
