• The radial load on the motor shaft must not exceed the values indicated in
the corresponding table. See the section on radial and axial loads.
• If the belt angle is not the right one, it may cause vibration or slippage.
• When applying an excessive load on the motor shaft, the ball bearings may
be seriously affected and their life drastically shortened.
• Make sure that the contact angle between the belt and the pulley its laying
on is
φ
= 140° or greater. Otherwise, it will generate some slippage. See
the section: Belt installation.
• To know the belt peripheral speed, its transmitted power and diameter
ratio, etc. refer to the data supplied by the belt manufacturer.
• Always use balanced pulleys.
Gear coupling. Considerations
• Make sure that the motor shaft is mounted parallel to the machine axis and
that the centers of the gears are in parallel alignement engaging perfectly.
• The gear teeth will deteriorate if they do not engage properly.
• Refer to the data supplied by the gear manufacturer.
Mounting a pulley or a gear to the motor shaft
• When installing a pulley or a gear to the motor shaft, take into account the
