2. Specify the operating conditions for the belt drive
Although this stage is sometimes difficult and time consuming it must be completed thoroughly if an appropriate unit is to be identified. You must understand the system in which the belt drive will operate so that the drive you Select is consistent with the rest of the system.

The prime function of a belt drive system is to transmit torque between two shafts, often with a change of angular velocity in the process.

The performance of the belt drive is thus concerned with the power it can transmit.

This is often expressed in terms of the torque and speed related to the two shafts. The speed ratio between them is also important, and there are limits to the ratio obtainable for one stage with a given belt type.

Ensure that the units used are appropriate for the parameters quoted.

Ensure that the units used are appropriate for the parameters quoted.

Other factors affecting belt system Selection are:

  1. The environment in which the belt drive must operate
  2. The consequences of failure
  3. Commercial factors
  4. Operation and maintenance
