8.2.1General safety notes for checking and changing lubricants

WARNING

Danger of scalding from the hot oil emerging from the unit.

Before starting any work wait until the oil has cooled down to below +30 ??C.

WARNING

Remove any oil spillage immediately with an oil-binding agent in compliance with environmental requirements.

NOTICE

Incorrect oil quantities can damage the gearbox.

The oil quantity and the position of the sealing elements are determined by the mounting position.

After removing the oil level screw, up to and including gearbox size 89, the oil level may not be more than 3 mm below the recommended filling level.

NOTICE

Dirt and damaging atmospheres can penetrate into the gearbox through open holes used to check or drain the oil.

Immediately close the gearbox after checking the oil level or changing the oil.

Note

For data such as type of oil, oil viscosity, and oil quantity required, refer to the rating plate. For oil compatibility see Recommended lubricants (Page 67).

Note

No oil changes are required.

Service and maintenance

8.2 Checking and changing lubricants

8.2.2Checking the oil level

NOTICE

The volume of gearbox oils changes with temperature.

If the temperature rises, the volume increases. Where temperature differences and filling quantities are significant, the increase can amount to several liters.

The oil level must therefore be checked while still slightly warm, approximately 30 minutes after switching off the drive unit.

Figure 8-1 Oil level in the gearbox housing

Procedure

1.Switch off the power supply to the drive unit.

2.Unscrew the oil level screw, see Mounting positions (Page 79).

Figure 8-2 Oil level in the oil sight glass

Top up the oil level ??? if necessary, and check it again.

8.2.4Checking the oil quality

Signs of changes in the oil can be seen with the naked eye. Fresh oil is clear to the eye, and has a typical smell and a specific product color. Clouding or a flocculent appearance indicates water and / or contamination. A dark or black color indicates residue, serious thermal decomposition or contamination.

Observe the symbols in the diagrams of the mounting positions, see Mounting positions (Page 79):

Procedure

1.Allow the geared motor to run for a short time. Wear and contaminant particles are visible in the oil shortly after shutting down.

2.Switch off the power supply to the drive unit.

3.Unscrew the sealing element at one of the points marked with the symbols listed above.

4.Remove some oil, using a suction pump and a flexible hose, for example.

5.Check the condition of the sealing ring on the sealing element and replace the sealing ring if necessary.

6.Seal the gearbox with the sealing element.

7.Check the oil for abnormalities. If you detect any abnormalities, change the oil immediately.

You have now checked the oil quality.

Service and maintenance

8.2 Checking and changing lubricants

8.2.5Changing the oil

8.2.5.1General safety notes for changing the oil

NOTICE

An impermissible mixture of oils will lead to clouding, depositing, foam formation, changes to the viscosity or reduced protection against corrosion and wear.

When changing oil of the same type, the residual volume of oil in the gearbox should be kept as low as possible. Generally speaking, a small residual volume will cause no particular problems.

Gear oils of different types and by different manufacturers must not be mixed. Have the manufacturer confirm that the new oil is compatible with the remaining volume of used oil.

If changing very different types of oil or oils with very different additives, always flush out the gearbox with the new oil. When changing from mineral oil to polyglycol oil (PG) or vice versa, it is vital to flush the gearbox twice. All traces of old oil must be completely removed from the gearbox.

NOTICE

Gearbox oils must never be mixed with other substances. Do not flush with paraffin or other solvents, as traces of these substances will always be left behind inside the gearbox.

Note

The oil must be warm. If it is too cold, it will flow too sluggishly to drain properly. If necessary, run the gearbox for 15 to 30 minutes to warm it up.

Service and maintenance

8.2 Checking and changing lubricants

8.2.5.2Draining the oil

Observe the symbols in the diagrams of the mounting positions, see Mounting positions (Page 79):

Procedure

1.Switch off the power supply to the drive unit.

2.Unscrew the vent plug.

3.Unscrew the oil level screw.

4.Place a suitable and sufficiently large receptacle underneath the oil drain plug.

5.Unscrew the oil drain plug and drain all the oil into the receptacle.

6.Check the condition of the sealing ring on the sealing element and if the sealing ring is damaged, replace the sealing element with a new one.

7.After draining the oil, immediately seal the gearbox using the sealing element.

You have now drained the oil from the gearbox.

Service and maintenance

8.2 Checking and changing lubricants

8.2.5.3Flushing the gearbox when changing between incompatible oils

NOTICE

Polyglycol oil has a higher density than mineral oil. Therefore, it sinks down towards the oil drain and the mineral oil floats on top.

This makes the required complete draining of mineral oil from the gearbox extremely difficult.

NOTICE

A flushing process is required with biodegradable and physiologically safe oils.

Note

After the second flush, we recommend that an an appropriate analysis institute checks the quality of the flushed fluid.

Observe the symbols in the diagrams of the mounting positions, see Mounting positions (Page 79):

Procedure

1.After the oil has been drained, wipe the gearbox clean of any remaining mineral oil using a cloth.

2.Unscrew the vent plug.

3.Fill the gearbox with a flushing oil, using a filter (filter mesh max. 25 ??m). For the flushing oil, use either the new oil or one that is compatible with the new oil and is less expensive.

4.Operate the gearbox for 15 to 30 minutes under a low load.

5.Place a suitable and sufficiently large receptacle underneath the oil drain plug.

6.Unscrew the oil drain plug and drain all the oil into the receptacle.

7.After flushing, immediately seal the gearbox using the sealing element.

8.Repeat this step for the second flushing.

You have now flushed the gearbox twice and can pour in the new oil.

5.Check the condition of the sealing ring on the sealing element and if the sealing ring is damaged, replace the sealing element with a new one.

6.After filling the oil, immediately seal the gearbox using the sealing element.

You have now filled up the gearbox with oil.

Service and maintenance

8.2 Checking and changing lubricants

8.2.6Topping up with oil

You may need to top the gearbox up with oil if the gearbox mounting position changes or if oil is lost due to a leak. If you notice oil escaping, locate the leak and seal the affected area. Top up and check the oil level.

At the time of going to print, the following types of oil are being used when the gearbox is filled for the first time:

CLP ISO VG220: ARAL Degol BG 220

CLP ISO PG VG220: Castrol Tribol 1300 / 220

CLP ISO PG VG460: Castrol Tribol 1300 / 460

CLP ISO PAO VG68: Addinol Eco Gear 68S-T

CLP ISO PAO VG220: Addinol Eco Gear 220S

CLP ISO E VG220: Fuchs Plantogear Bio 220S

CLP ISO H1 VG460: Kl??ber Kl??beroil 4 UH1 460 N

If, following agreement, gearboxes are filled at the factory with special lubricants for the special applications referred to above, this is shown on the rating plate.

8.2.7Changing the roller bearing grease

The roller bearings are lubricated in the factory with the greases listed in the table.

When changing the oil, the specified grease quantity of grease-lubricated bearings should also be replaced.

Clean the bearing before filling it with fresh lubricant.

In the case of bearings on the output shaft or intermediate shafts, the grease quantity must fill 2/3, and in the case of bearings on the input side, 1/3 of the space between the rolling elements.

Service and maintenance

8.2 Checking and changing lubricants

8.2.8Service life of the lubricants

Note

In case of ambient conditions deviating from normal conditions, e.g. high ambient temperatures, high relative humidity, aggressive ambient media, the intervals between changes should be shorter. In such cases please contact Technical Support for assistance in determining the individual lubricant change intervals.

Note

Oil sump temperatures above +80 ??C can reduce service life. In this context, the rule is that increasing the temperature by 10 K will approximately halve the service life, as illustrated in the figure titled "Guide values for oil change intervals".

For a +80 ??C oil sump temperature, the following service life can be expected when observing the properties specified by Siemens AG:

Note

These recommendations are not a guarantee of the quality of the lubricant provided by your supplier. All lubricant manufacturers are responsible for the quality of their own products.

Service and maintenance

8.2 Checking and changing lubricants

The oil selected for use in the gearbox must be of the viscosity stated on the rating plate (ISO VG class). The viscosity class indicated applies for the contractually agreed operating conditions.

In the case of different operating conditions, please contact Technical Support.

If, following agreement, gearboxes are filled at the factory with special lubricants for the special applications referred to above, this is shown on the rating plate.

The quality of the oil used must comply with the requirements laid down in the BA 7300 Operating Instructions; otherwise, the Siemens warranty is null and void. We urgently recommend using one of the oils listed in the released and recommended lubricants T 7300 (http://support.automation.siemens.com/WW/view/en/44231658), which were appropriately tested and comply with the requirements.

The oils listed there are subject to continuous testing. Under certain circumstances, it is therefore possible that the oils recommended there are at a later point in time removed or replaced by oils that have been further developed.

We recommend that you regularly check as to whether the selected lubricating oil is still recommended by Siemens. Otherwise, a different oil type should be selected.

Service and maintenance

8.3 Checking the gearbox for leaks

8.3Checking the gearbox for leaks

Note

From the inherent principle of operation, oil mist can escape from the vent valve or a labyrinth seal.

Oil or grease escaping in small quantities from the shaft sealing ring should be regarded as normal during the running-in phase of 24 hours operating time.

If the quantities escaping are significant or leaking continues after the running-in phase, the shaft sealing ring must be replaced to prevent consequential damage.

Shaft sealing rings are subject to natural wear. The service life depends on the operating conditions. We recommend that shaft sealing rings are included in periodic maintenance and servicing work on the system.
