Example of Timing Pulley Use

Example of Use
■Timing Pulley Mechanism name
Belt tension device (manual)

■Mechanism function
1. Move the roller on the adjustment side, and tighten and fix it when the conveyor belt opens.
2. For multiple driving applications, the engagement rate can be improved by setting the roller in the middle position.

■ Role of the timing belt idler
1. The belt is tensioned by fixing the belt assembly distance with the timing belt idler
and with the assistance of the urethane roller.
