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

■More Convenient On-site Assembly
·MISUMI Economy series Timing Pulley is chamfered at the shaft hole and tapped hole for easy installation, reducing assembly time by 27% compared to the timing pulley not chamfered.

Features of Timing Pulley

* The values above are averages of test data and may vary individually.

■Longer Timing Belt Life
·MISUMI Economy series Timing Pulley, with deburring treatment at the tapped hole, is not easy to wear the timing belt, and the price is cheap while increasing the lifetime of the timing belt.

Usage of Timing Pulley Method

Usage Method Example of Timing Pulley Drawing	Usage Method of Timing Wheel and Timing Belt
	①Timing Pulley Driving The driven wheel is driven by the driving wheel for transmission
	②Timing Pulley Linear driving Reciprocating motion is carried out through the self-end timing toothed belt.

Usage Method Example Drawing	Usage Method of Timing Wheel 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 3M timing belt idlers, suitable for MISUMI HTD 3M timing belts.

Example of Timing Pulley Use

Example drawing of a workpiece reversal transfer mechanism designed using MISUMI timing pulley

■Timing Pulley Mechanism name
Workpiece Reversal Transfer Mechanism

■ Mechanism function
The workpiece moving on the conveyor belt rotates 90 degrees and then transfers to the next process.
Timing Pulley The chuck mechanism rotates 180 degrees and transfers the workpiece without changing the direction of the workpiece relative to the conveying direction.

■Role of the timing pulley
The transmission of the timing pulley and the timing belt changes the placement direction of the workpiece while transferring the workpiece. (Applicable to S specification and GT specification timing pulleys)
