Abstract

An improved drive mechanism for a conveyor. An endless belt is mounted for travel on the frame of the conveyor and is driven by a drive unit. The drive unit includes a supporting structure or housing that carries a power source, such as a motor. The output shaft of the motor is connected by a flexible drive member to a pair of drive spindles that support the conveyor belt. The drive unit also includes a pair of belt tensioning spindles which are journaled for rotation on slides that are mounted for movement on the supporting structure of the drive unit. A drive mechanism, such as a fluid cylinder, is operably connected to the slides to move the slides in unison to tension the belt.
