If you are referring to the Elex make Ratchet and Pin Wheel used in conveyor belt self-aligning systems, here is a suitable technical description:
The Ratchet and Pin Wheel (Elex Make) is a mechanical assembly used in conveyor belt self-aligning systems to maintain proper belt tracking. It converts the movement of the self-aligning idler frame into controlled, stepwise rotational motion, helping correct belt misalignment and preventing excessive movement of the alignment mechanism.
The assembly consists of a cast iron pin wheel with equally spaced pins around its circumference and a hardened steel ratchet lever (pawl). When the conveyor belt drifts from the center, the self-aligning mechanism actuates the ratchet, which engages the pin wheel to rotate it incrementally. This action repositions the self-aligning idler and guides the belt back to its central path.
This mechanism helps reduce belt misalignment, minimizes edge damage and spillage, and improves the reliability and service life of conveyor systems
