Main Drive Pulley OVS-25 (OVI 00.103)

Main Drive Pulley OVS-25 (OVI 00.103)

Pulley OVI 00.103 is one of the key pulleys in the drive system of OVS-25 grain cleaning machines. It is a drive pulley that is mounted on the shaft of the main electric motor, which is responsible for operating the entire cleaning unit.

The pulley (OVI 00.103) is a massive cast iron single-groove part. Its task is to take power from the main motor and transmit it to the intermediate pulley (OVI 00.106). From this intermediate assembly, the rotation is distributed to two main units of the machine:

1. Fan (drive to pulley OVI 03.101)
2. Sieve mills (drive to the eccentric shaft, pulley OVI 02.101)

Thus, this pulley is the initial link in the drive system for the entire OVS-25 cleaning system. It has a 28 mm mounting bore with a keyway for a secure fit on the electric motor shaft.
