Drive assembly for a modular conveyor
A modular conveying assembly including a plurality of modules joined together, each module including a bushing housing, a coupling housed in the bushing housing, an axle coupled to the coupling and supported for rotation relative to the module, a drive pin coupled to the coupling, and a driven surface fixed to the drive pin. The modular conveying assembly also including a driving member that is in selective engagement with the driven surface to affect rotation of the axle.
1. A modular conveying assembly comprising:
a plurality of modules joined together, each module including
a bushing housing,
a coupling housed in the bushing housing,
an axle coupled to the coupling and supported for rotation relative to the module,
a drive pin coupled to the coupling, and
a driven surface fixed to the drive pin; and
a driving member in selective engagement with the driven surface to affect rotation of the axle.
2. The modular conveying assembly of claim 1 , wherein the drive pin includes a barbed shaft and the driven surface receives the barbed shaft.
3. The modular conveying assembly of claim 1 , wherein the driven surface is a part of the drive pin.
4. The modular conveying assembly of claim 1 , wherein the drive pin has a shoulder that extends radially outward and is arranged adjacent the bushing housing.
5. The modular conveying assembly of claim 1 , wherein the axle is splined.
