Product of Timing Pulley Overview
Usually, Timing Pulley, timing idlers and timing belts are widely used to design mechanisms for transmitting rotational power generated by motors. Driving and transmission are realized through the engagement between the teeth of timing pulleys, timing idlers and timing belts.
Product of Timing Pulley Features
■Tooth Profile Engagement of MISUMI Economy series Idlers
・MISUMI Economy series idlers tooth profiles conform to JIS and ISO standards, matching with the standard belt tooth profile for smoother rotation.
* Problems of generic products in the market
■Rotation Stability of MISUMI Economy series Idlers
・MISUMI Economy series idlers tooth profiles conform to JIS and ISO standards, matching with the standard belt tooth profile for smoother rotation.

Usage of Timing Pulley Method
| Usage Method Example of Timing Pulley Drawing | Instructions for Use of Timing Belt Idlers and Timing Belt |
 | ①Timing Pulley Belt tensioning Adjust the tension on the inside of the timing belt via the timing belt idler. |
 | ②Timing Pulley Linear driving Reciprocating motion is carried out through the self-end timing toothed belt. |
| Usage Method Example Drawing | Instructions for Use of Timing Belt Idlers and Timing Belt |
 | ③Timing Pulley Conveyance Plates are conveyed by two timing toothed belts |
 | ④Timing Pulley Traction transmission Workpieces are clamped and transmitted by the belt |
HTD timing belt idlers, suitable for MISUMI Economy series HTD Timing Belts.Example of Timing Pulley 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.
