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.
