Live roller conveyor pulley for improving the training of a conveyor belt

A motorized conveyor roller comprising:

• means for rotatably mounting a roller tube in a conveyor frame, the roller tube having two ends, a length, an inner diameter and a hollow interior providing a first section and a second section, the roller tube having disposed within the first section of the hollow interior disposed proximate one end of the roller tube, a motor and a gear reducer, mounted on a stationary shaft, the gear reducer being disposed adjacent said motor and operatively connected to the motor, said gear reducer including an output;
• a drive member being driven by the gear reducer output to drive said roller tube, a lubricant contained within the first and second section of the hollow interior for lubricating and cooling the motor, the gear reducer, the gear reducer output, and the inner diameter of the roller tube, the second section of the hollow interior of the roller tube being defined by the end of the roller tube remote said first section of the roller tube and the adjacent end of first section of the roller tube, the second section of the roller tube having compressible insert means disposed therein which engages with the inner diameter of the roller tube when inserted therein and which substantially remains in place as the compressible insert means presses again the interior diameter of the roller tube, the compressible insert means for ensuring that the lubricant is uniformly distributed about the inner diameter and length of the second section of the roller tube which does not contain the motor, the gear reducer, or the gear reducer output, whereby the temperature of the lubricant and the roller tube across the length of the roller tube is substantially uniform.
