1.1.4 Initial lubrication of the drive unit respectively control of the oil level

Drive units are delivered greased with longlife grease. The drive unit has to be regreased before the initialoperation.

Utilize water-repellent lithium-soap-grease according to DIN 51 825 TI of NLGI-class 2 DIN 51 818 for the

raceway.

See chart 7 for greases fit for use.

Lubrication of the housing ( for units, filled with grease )

Press grease into all grease nipples of the drive unit while revolving the drive unit in the mean

time, until a continuos grease collar forms under the open seal.

Apply a small amount of grease beyond the seal lip of the close seal, utilizing for instance a

brush, to enable a wear resistant run of the seal.

Control and refilling of the oil level ( for units, filled with oil )

Apply a small amount of grease beyond both of the seal lips, utilizing for instance a brush, to

enable a wear resistant run of the seal.

Open the oil inlet screw to check the oil level

If the drive unit is not filled with oil completely to the edge of the inlet drilling, fill oil into the unit, until

the edge of the inlet drilling.

When the unit is filled completely, close the inlet screw.

- Use this bore as inlet bore, that occupies the highest position, relative to the planed fitting

position.

1.1.5 Choice of the fixing screws

Only the prescribed screws may be utilized to fix a drive unit to the supporting structure.

The prescribed size, number and quality of the screws has to be observed.

- The function and durability of the drive unit is determined substantially by the durability of

the screw connection.

- If washers are utilized, to equalize unevenness, the maximum admissible surface stress

may not be exceeded.

- Toughened washers have to be used any time, screws of the quality 10.9 or 12.9 are

utilized.

- The clamp lengths ( clamp lengths referring to the diameter of the screw ) has to be 5.

If differences occur, please talk to our technical staff.

- Use only new screws, nuts and washers any time a drive unit is mounted or replaced.

1.1.5 Choice of the tightening torque of the screws

Under normal conditions the screws are secured sufficiently against loosen, by correct preloading.

- Additional retention of the screws is possibly necessary, if shock loads or vibrations

happen regularly.

- Lock-washers, spring-washers or resembling may never be used.

1.2.2 Fixing of the drive unit

- Drive units may only be fixed to a surface utilizing the designated screw holes.

It is, in no way, permissible to weld them to the supporting structure, or to perform welding

procedures in the surrounding of the supporting structure, because this may lead to an

irreparable distortion in the housing and because of that to an early breakdown.

When mounting a drive unit to the supporting structure, mount the housing first and then the revolving part. This

mounting procedure has to be performed, free of external loads.

In all connections parallel screw axes against each other in a load free condition and parallel screw axes to the

separation gaps standards are assumed.

Furthermore the fixing holes of the base - and the revolving part of the drive unit and the supporting structure have

to resemble each other exactly, in any other case the drive unit will be preloaded.

- To avoid intolerable deviations between torque moments of the screws stick to the

following procedure.

Screwing

Screw the base part of the drive unit to the surrounding structure first.

Apply a small amount of oil to the screws to ensure a constant friction coefficient ( not if screw

retention is utilized ).

If screw retention is used, stick to the instruction of these products.

Tighten the screws, possibly with washers, loose.

Tighten the screws at the loose screwed base part in an over cross pattern.

Preload the screws step by step up to the stipulated value.

Now fix the revolving part of the drive unit by repeating the procedure above.

- If a hydraulically tightening device is used the preload may not exceed 90 % of the elastically

values.

The tighten torque moment ( according to chart 3 ) is determined by many factors, especially by the friction

value of the thread and can vary heavily in practice.

1.2.3 Determination of the actual tilting clearance

The tilting clearance increases when the drive unit is built-in.

To determine the increase of the tilting clearance, the tilting clearance has to be measured at the built-in, not yet

operated drive unit.

- Mark the measurement point ( for instance with a taped ) in the main load direction at

both base - and revolving part, to have a fixed measurement point for subsequent checks.

- Note and archive all measured values.

Checking of tilting clearance

Determine and mark the measurement point, if possible, in the main load direction at the base

part and at the revolving part.

Check the distance between base part and revolving part, as shown in sketch 3

First, fix a dial gauge with a measurement arm at point "A" of the sketch. The feeler of the dial

gauge must lay at point "B" of the sketch.

The revolving part has to be tilted in the "1" direction of the sketch, utilizing a determined force.

Nil the dial gauge.

Now create a tilting moment into the 2 direction of the sketch by a determined force.

The value now shown on the dial gauge is equal to the tilting clearance.

- All further checking procedures have to be performed at the same measurement point with

the same loads, with the same position of base - and revolving part against each other, by

utilizing the measurement method indicated.

- Note and archive the measured values for further checks as reference values.

Sketch 3 measurement of tilting clearance

The presently measured tilting

clearance is seen as a reverence

value for later checks, in case of

later checks, the procedure above

has to be utilized.

1.2.4 Determining the actual rotation clearance

In order to determine the increase of the rotation clearance, the rotation clearance has to be measured at a

mounted, not yet operating drive unit.

- Mark the measurement point at the base- and at the revolving part respectively at the structure

( for instance with tap numbers ), to have a fixed measurement point for later checks.

- Note and archive all measured values.

Initial determination of the rotation clearance

Determine and mark the measurement point at the base- and at the revolving part.

The measurement point has to be at the external diameter of the revolving part.

A dial gauge has to be fixed to the base part utilizing a measurement arm, as shown in sketch 4.

force

Nil the dial gauge.

Now rotate base- and revolving part clockwise against each other, utilizing a determined force.

The value, now shown on the dial gauge, is equal to the rotation clearance.

- All subsequent checks have to be performed at the same measurement point with the same

loads, the same position of base part and revolving part against each other and by utilizing the

same measurement method

- Note the measured values for further measurements, and archive them as reference values for

further checks.

The presently measured rotation clearance

is seen as a reference value

for further checks, further checks have to

stick to the same procedure.

1.2.5 Connecting the hydraulic system and the motor.

If the drive unit has to be delivered without motor, the motor has to be connected now. After that the hydraulic

system has to be connected.

Depending on the construction, the drive unit can be also equipped with 2 motors.

In this case connect both motors, and connect both hydraulic systems of the motors.

Stick closely to the instructions of the motor- and hydraulic manufacturers.

- It is not permissible to operate a drive unit, that is constructed to be driven by two motors with

just one motor.

It now has to be possible to revolve the drive unit with correctly bolted base part, revolving part and motor

constantly by hydraulic means.

The influence of loads and possible deviations at the connection surfaces above and beyond the drive unit can

increase the rotation resistance.

In case of a rotation resistance, that exceeds the specifications, the drive unit has to be disconnected from the

surrounding structure, and the rotation resistance has to be measured in a not connected condition.

Functional testing

Revolve the mounted drive unit a few times.

Check if the drive unit runs smoothly and even.

Perform further testing runs under full load.

- After the test run, check the drive unit again. If it is necessary retighten the screws up to the

described values.

1.2.7 Permissible revolving speed and permissible revolutions

- Depending on type, and kind of lubrication of the drive unit, different numbers of revolutions are

permissible. This is described further in our offer. In case of units that are delivered without

motor, contact to our technical department.

Depending on constructive base, drive units are not suited as continuos running devices.

1.2.8 Varnishing the drive unit and the surrounding structure

- Connection surfaces may not be varnished.

- No paint may spill on the seal or the connecting surface of the seal, this can corrode the seal,

or stick the seal lip to the connecting surface.

This surfaces have to be covered with adhesive tape before the painting procedure.

2. Maintenance / safety checks and lubrication

2.1. Check of the fixing screws

The tightening screws have to be checked every 700 operating hours or at least every 6 months. This time

schedule has to be adjusted ( lowered ), if special working conditions apply.

- The tightening moments of the fixing screws have to be checked after the first 100 operating

hours, but at least after the first month in service in order to equalize possible settling effects

and the screws have to be retighten to the values indicated in chart 3

- After this initial test retighten the tightening screws every 700 operating hours respectively after

the appropriate adjusted ( shorter ) time schedule, this test has to be performed at least every 6months, depending what time is reached earlier.

If this is not performed, personal and installations can be endangered.

Check the tightening value utilizing a torque wrench and adjust them to the values in chart 3.

Replace loosened screws.

- Only new screws and washers are suited to replace single loose screws, respectively to

replace the drive unit.

2.2 Checking of the tilting clearance

Wear in the raceway system leads to an increase in the tilting clearance.

Because of that, the tilting clearance has to be checked in certain, regular, intervals.

- Check the tilting clearance after 700 service hours, but at least after 6 months

Failure to do this may endanger personal and installations.

Checking of the increase of the tilting clearance K , if the tilting clearance can be measured directly

at the diameter of the borecircle of the worm wheel.

For the procedure of checking the tilting clearance look at page 7, point 1.2.3 .

The value measured first, at the installation of the drive unit ( m1) serves as a base value for the checking

measurements ( mx). The value of the initial measurement is subtracted from the value of al subsequent

measurements. This value may not exceed the removal clearance.

interval has to be lowered even further ( to 50 - 100 service hours ).

- If the removal clearance of the rotation clearance is exceeded, the machine has to be shut

down and the drive unit has to be exchanged.

2.4 Checking of the seals

If a seal fails, because of wear, mechanical, respectively chemical influence it has to be renewed. Seals have tobe checked at every control of the screwing.

The seal can be purchased from our house as piece goods together with glue and fitting instructions.

2.5 Lubrication of oil filled drive units

Use the same product for the lubrication of the interior of the housing.

Use Polyalphaolefin oils for lubrication of the housing, if there are no contradictory instructions on any

supplement sheets. Check chart 8 for greases, suited for service.

- All legal - and manufacturer instructions for the usage of lubricants have to be put into

consideration.

- Take the bore that occupies the highest position, relative to the planed installation position, as

inlet bore.

- Always take the bore, that occupies, relative to the planed installation position, the lowest

position as oil run - out bore

- Waste oil may only be disposed by qualified firms

Maintenance :

Take, for instance, a brush to put a small amount of grease beyond the lip of both of the seals,

to ensure a low - wear run.

Screw the oil - inlet - screw open and check the oil level.

If the drive unit was not filled with oil completely, fill in new oil up to the edge of the inlet bore

After the unit is filled completely, close the inlet screw again.

If more than an appropriate amount of oil is missing, check all seals for a possible leak.

2.7 Lubrication intervals for grease - respectively oil - filled drive units

Lubrication intervals mainly depend on the kind of lubrication, the working conditions, the environmental

conditions, the type of the drive unit and the number of operating hours.

Exact relubrication intervals can only be determined through testing under realistic conditions.

If no comparable test results are present, the following chart can be taken as estimated data.

Oil filled units are filled with a polyalphaolefin oil, if no contradictory information is noted on a supplement sheet.

This kind of lubrication has the advantage of increased stand times, higher possible rotation speed and lower

wear.

Because of that changed data applies :

Viscosity

Viscosity has to be between 320 and 680 according to ISO VG. When choosing the viscosity please also

consider the lowest possible temperature of usage because, in case of increasing viscosity, the liquidity

decreases and, because of that, power losses increase.

In case of general questions concerning the viscosity values please talk to our technical department. In case of

more specific questions, please talk to the manufacturer directly.
