General technical data Part 4

Bearings and lubrication

Bearing lifetime (nominal lifetime)

The nominal bearing lifetime is defined acc. to standardized calculation procedures (DIN ISO 281) and, for 90 % of the bearings is reached or even exceeded when the motors are operated in the compliance with the data provided in the catalogue.

Under average operating conditions, a lifetime (L_h10) of 100,000 hours can be achieved.

Generally, the bearing lifetime is defined by the bearing size, the bearing load, the operating conditions, the speed and the grease lifetime.

Bearing system

The bearing lifetime of motors with horizontal type of construction is at least 40,000 hours if there is no additional axial loading at the output coupling and at least 20,000 hours with the maximum permitted loads.

This assumes that the motor is operated at 50 Hz. The nominal bearing lifetime is reduced for converter-fed operation at higher frequencies.

For the maximum vibration values measured at the bearing plate, evaluation zones A and B specified in ISO 10816 are applicable in order to achieve the calculated lifetime under continuous duty. If higher vibration speeds will occur under the operating conditions, special arrangements will be necessary (please enquire).

For standard motors applies the following:

In the basic bearing system, the floating bearing is situated at the drive end (DE) and the located bearing (axially located from Type of construction 160 and above) is situated at the non-drive end (NDE). On request, the located bearing can also be supplied at the drive end (DE) (Fig. 3, Page 1/63).

For 1LA8, 1PQ8 and 1LL8 non-standard motors applies the following:

In the basic bearing system, the floating bearing is situated at the non-drive end (NDE) and the located bearing is situated at the drive end (DE).

On request, the located bearing can also be supplied at the non- drive end (NDE).

For ordering all standard and non-standard motors quote

order codeK94.

The bearing system is axially preloaded with a spring element to ensure smooth running of the motor without play.

This is not the case in versions with parallel roller bearings. The bearings of these motors must always run under adequate radial force (motors must not be operated on a testbed without additional radial loads).

Motors of series 1LA6, 1LA7, 1LA9 and 1MA7 up to and including Type of construction 132 have a “floating” bearing arrangement (see Fig. 1, Page 1/63).

Up to Type of construction 132, an additional axially-secured located bearing can be supplied on the non-drive end (NDE) complete with a retaining ring (see Figure 2, Page 1/63).
Order codeL04

For Type of construction 160 and above, bearings are usually axially located (see Figures 2, 4 and 5, Page 1/63).

For increased cantilever forces (e.g. belt drives), reinforced bearings can be used at the drive end (DE).
Order codeK20

Motors 1LG4/6 in Type of constructions 180 to 315, 2-pole, can be supplied with reinforced deep-groove bearings (size range 03).
Special bearings for DE and NDE, bearing size 63
Order codeK36

A measuring nipple for SPM shock pulse measurement is mounted to check bearing vibration. The motors have 1 or 2 tapped holes per bearing plate and a measuring nipple with a protective cap. If a second tapped holes is provided, it is fitted with a sealing cap.
Order codeG50

Bearing arrangement for increased cantilever forces on Pages 1/61 and 1/62 – maximum loading on Pages 1/66 and 1/67.

Insulated bearings

To prevent damage as a result of bearing currents, insulated bearings can be supplied at the non-drive end NDE from Type of construction 225 to 315 and are recommended for Type of construction 225 and above. This bearing design is also possible for 1MJ7 motors from Type of construction 250 to 315.

Order codeL27

The insulated bearing is standard for all 1LA8, 1PQ8 and 1LL8 motors which are identified for converter-fed operation.

Permanent lubrication

For permanent lubrication, the bearing grease lifetime is matched to the bearing lifetime. This can, however, only be achieved if the motor is operated in accordance with the catalogue specifications.

In the basic version, the motors up to and including shaft height 250 have permanent lubrication.

Regreasing

For motors which can be re-greased at defined re-greasing intervals, the bearing lifetime can be extended and/or unfavourable factors such as temperature, mounting conditions, speed, bearing size and mechanical load can be compensated.

From a shaft height of 280 upwards, regreasing with an M10 x 1 flat greasing nipple to DIN 3404 is provided.

It is possible to regrease motors, shaft heights 100 to 250.
A lubricating nipple is optionally provided.
Order codeK40

Mechanical stress and grease lifetime

High speeds that exceed the rated speed with converter-fed operation and the resulting increased vibrations alter the mechanical running smoothness and the bearings are subjected to increased mechanical stress. This reduces the grease lifetime and the bearing lifetime (please enquire where applicable).

For converter-fed operation in particular, compliance with the mechanical limit speedsn_max at maximum supply frequencyf_max is essential, see the section “Motors operating with frequency converters”.

Please enquire about noise and vibration data. For NU bearings, in contrast to standard bearings, a minimum cantilever force is required. The bearing selection tables are only intended for planning purposes. Binding statements about the bearings for motors which have already been shipped can be requested. Please specify the serial number.

The motors are transported horizontally; they can be transported vertically at additional cost on request.
Reinforced bearings are available for Type of constructions 400 and 450 as well as IM V1 types of construction as well as for 1LL8 motors on request. Please specify cantilever force and dimension x. Reinforced bearings cannot be supplied for 2-pole motors.

Maximum cantilever forces

Maximum cantilever forces, basic version

In order to calculate the maximum cantilever forces for a radial load, the line of force (i.e. the centreline of the pulley) of the cantilever forceFQ (N) must lie within the free shaft extension (dimension X).

Dimension x [mm] is the distance between the point of application of forceFQ and the shaft shoulder. Dimension xmax corresponds to the length of the shaft extension.

Total cantilever forceFQ = c · Fu

The pre-tension factor c is a value gained from experience from the belt manufacturer. The following approximate value can be assumed:

For normal flat leather belts with an idler pulleyc = 2;
for V-beltsc = 2 to 2.5;
for special synthetic belts (depending on the type and load)c = 2 to 2.5.

The circumferential force Fu (N) is calculated using the following equation

F ucircumferential force in N

P rated motor power (transmitted power) in kW

n Fan speed in rpm

D pulley diameter in mm

The pulleys are standardized acc. to DIN 2211, Sheet 3.

The maximum cantilever forces at 60 Hz are approx. 80 % of the 50 Hz values (please enquire).

¹⁾ Data for 1LL8 is available on request

²⁾ Data for 1MJ1 Type of constructions 355 to 450 will be available soon.

For 1LA8 motors in horizontal type of construction, the maximum cantilever forces are specified with regard to the axial forces.

It should be observed that for types of construction IM B6, IM B7, IM B8, IM V5 and IM V6 the belt tension is only permitted to act parallel to the mounting plane or towards the mounting plane and the feet must be supported. Both feet must be secured for foot-mounting types of construction.

Refer to pages 1/66 to 1/69 if the cantilever forces are higher than those listed above.

The values shown do not assume a cantilever force on the shaft extension.
The maximum loads are valid for operation at 50 Hz; for 60 Hz, please enquire.
The calculation of the maximum axial load was based on the drive with generally available coupling. For suppliers, see the relevant section of the catalogue “Accessories and spare parts”.
Please enquire regarding 1MJ8 and 1MJ1 motors.
Please enquire if the load direction alternates.

Values shown without assuming a cantilever force on the shaft extension.
The maximum loads apply to operation at 50 Hz; please enquire about 60 Hz.
The figures for the maximum axial loads have been calculated assuming that standard coupling types are used for the drive. For suppliers, see the relevant section of the catalogue “Accessories and spare parts”.
Please enquire if the loading direction alternates.
