Eccentric Shaft Pulley OVS-25 (OVI 02.101)

Eccentric Shaft Pulley OVS-25 (OVI 02.101)

Pulley OVI 02.101 is used in the "Eccentric Shaft OVI 02.140" assembly, which is a key component of the "Sieve Unit OVI 02.000" of OVS-25 grain cleaning machines and their modifications.

The pulley (OVI 02.101) is a double-groove (double-belt) part made of cast iron. It has two grooves of different diameters and performs two functions:

1. Sieve Mill Drive
   The large groove (290 mm) is driven and receives rotation from the intermediate pulley (OVI 00.106), driving the eccentric shaft (OVI 02.601). This rotation creates the oscillating movements necessary for the operation of the sieve mills.
2. Cleaning Mechanism Drive
   The small groove (120 mm) is driving and serves to transmit rotation (via belt A-1800T) to the drive (OVI 02.250) of the sieve cleaning mechanism (brushes).

Thus, this pulley is central to the sieve unit, synchronizing the movement of the sieve mills and their cleaning brushes. It has a 35 mm mounting bore with a keyway.
