An interlocking torque tube-pulley assembly as provided for live roller, line shaft conveyor systems. The assembly is actually disposed along a rotating drive shaft and generally includes a number of drive pulleys with spacer members interposed therebetween. The drive pulleys and the spacer members snap together by an overlap of materials with a locking feature. When interlocked, the pulley and spacer members are connected to the conveyor rollers of the conveyor system by endless drive belts. In this manner, an accumulation zone of conveyor rollers is formed wherein a 'positive drive' is provided by the disclosed torque tube-pulley assembly. In an alternate embodiment, the spacer members are provided in a segmented form wherein two spacer half members are adhesively joined by a collar portion. In this second embodiment, the distance between the pulley members on the assembly may be varied to accomodate the spacing between the conveyor rollers of the conveyor system.
