Abstract
In a motorized conveyor pulley of the type comprising a cylindrical pulley drum with axially opposite end plates enclosing an electric motor and drive transmission, the pair of end plates of the pulley are constructed with an increased axial thickness compared to prior art end plates and are supported on a pair of shaft ends by pairs of bearings and are sealed by a pair of lubricant seals between each pair of bearings. The enlarged end plates and the pairs of bearings resist bending loads exerted on the conveyor pulley by the conveyor belt and thereby reduce loading stresses on the motor and drive transmission contained in the pulley permitting more economical manufacture of the motor and drive transmission.
