Product of Timing Pulley Overview

Economy series products of Timing Pulley, please order more than 2 pcs

Usually, flat-belt Timing Pulley and flat belts are widely used in mechanisms design for transmitting rotational power generated by motors.
Driving and transmission are realized through the friction fit between flat-belt pulleys and flat 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.

Product Features
* The values above are averages of test data and may vary individually.
Product Features
■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 DrawingUsage Method of Timing Wheel and Timing Belt
Usage Method①Timing Pulley Driving
The driven wheel is driven by the driving wheel for transmission
Usage Method②Timing Pulley Linear driving
Reciprocating motion is carried out through the self-end timing toothed belt.
Usage Method Example of Timing Pulley DrawingUsage Method of Timing Wheel and Timing Belt
Usage Method③Timing Pulley Conveyance
Plates are conveyed by two Timing Pulley toothed belts
Usage Method④Timing Pulley Traction transmission
Workpieces are clamped and transmitted by the belt
Timing PulleyHTD 8M timing pulleys, suitable for MISUMI HTD 8M timing belts.

Example of Timing Pulley Use

Example of Use
■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.
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)
