Loading Conveyor Pulley OVS-25 (OVI 05.102)

Loading Conveyor Pulley OVS-25 (OVI 05.102)

Pulley OVI 05.102 is used in the "Upper Section OVI 05.010" assembly, which is a component part of the loading conveyor (OVI 05.000) of OVS-25 grain cleaning machines and their modifications.

The pulley (OVI 05.102) is a driven pulley (large wheel) of the upper part of the loading conveyor. Its main task is to receive torque via a belt drive from the electric motor's drive pulley (OVI 00.106) and to drive the upper shaft (OVI 05.602). This shaft pulls the scraper chain, which lifts the grain mass for feeding onto the sieve mills.

Structurally, it is a massive single-groove (single-belt) part made of cast iron. A key feature of this pulley is the presence of three cast cams on the hub. They are part of a locking cam clutch that engages with the corresponding cam (OVI 05.007). This mechanism prevents the conveyor from moving in reverse, stopping the chain from sliding down under the weight of the grain when the machine is stopped.
