Abstract
A motorized conveyor pulley comprises a cylindrical pulley drum with axially opposite end plates enclosing an electric motor and a drive transmission within the drum. The end plates of the pulley are mounted on a pair of shaft ends that pass through the end plates at the axially opposite ends of the pulley and support the motor and drive transmission in the pulley as well as supporting the pulley drum housing for rotation. As well as the motor and transmission, the pulley drum housing also contains an amount of lubricant that lubricates the bearings and gears of the drive transmission and cools the motor. A passive lubrication collector and manager is mounted in the pulley drum housing and wipes lubricant from the interior surface of the pulley drum housing and then directs the wiped lubricant to the bearings and gears of the drive transmission. The passive lubrication collector and manager is also used in combination with journal collars that support the journal ends of shafts of the drive transmission where the journal collars have openings that are fed with lubricant by the lubrication collector and manager, enabling use of the less expensive sleeve bearings. The cover also shie…
