3 GEARBOX START-UP
3.1 MOTOR SPECIFICATIONS
3.1.1 Dimensions and tolerances
The motor applied to the gearbox should comply with the following specifications:
• Size and power admitted by the gearbox
• Motor with seal on the shaft*
• Construction tolerances according to DIN 42955-R (see below)
• Vibration level R
* The motor seal is necessary to prevent oil from getting into the motor and damaging it: the
gearbox seal can have a small leakage over time that is drained outside the motor flange
3.1.2 Motor balancing
Motors can be supplied with key or with straight shaft (no key).
In case the motor has a key, it can be balanced in two different ways, i.e. with half key or with full key.
The gearbox must be balanced according to the balancing of the motor shaft, to avoid
unwanted vibrations and the balancing way must be specified when ordering the gearbox
(see chapter 1.6).
