DESCRIPTION

4.5.2 Maintenance

For all information on maintenance and lubrications,

see the manual of the gearbox.

Check the oil level regularly. If necessary, refill the oil

level. Avoid mixing oils of different types. In case

of doubt, change the oil completely. Also check that

there are no metallic parts with unusual dimensions in

the oil.

Special attention must be paid to very loaded output

stages and with very low speeds (<1 rpm). In such

cases, always use high viscosity oils with a good

amount of Extreme Pressure (EP) additive.

Gearboxes, which are not particularly loaded and that

have a discontinuous operating cycle without

considerable temperature ranges, can be lubricated

with mineral oil.

When the gearboxes are heavily loaded and used in a

continuous way, this can result in temperature increase.

In this case, it is best to use polyalphaolefin synthetic

lubricants (PAO). Use a synthetic lubricant when the

ambient temperature is below -20 °C.

For special applications where high powers and speeds

are involved, consult your Bredel representative.

4.6 Electric motor

The standard-supplied electric motor is a completely

enclosed three-phase asynchronous motor.

The interface between motor and gearbox is an IEC or

Nema flange.

The motor connection must meet the local applicable

regulations. A thermal safety device should reduce the

risk of a motor overload. For connecting PTC

thermistors (if present) a special thermistor relay must

be used.

In case of doubt, contact your Bredel representative for

advice.
