Product Features

■Usage difference between economy series timing pulleys and MISUMI standard product / Example of customer use

	Economy series Timing Pulleys	MISUMI Existing Products
Example of Use
Precautions	Generally used in reciprocating and conveyance mechanisms that require medium positioning accuracy	Generally used in mechanisms that frequently rotate forwardly and reversely and have requirements on positioning accuracy and backlash.
Repetitive positioning accuracy (reference value)	Medium precision (±0.1)	High precision (±0.05)

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

MISUMI Timing Pulley Assembly Time

* 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 threaded hole, is not easy to wear the timing belt, and the price is cheap while increasing the lifetime of the timing belt.

Belt condition after the test of timing belt pulley without chamfer on the threaded hole:
there are obvious wear marks left by the pulley tooth threaded hole on the belt tooth surface.
Photo of Belt Wear

[Test conditions]
Belt series: S5M
Belt width: 150mm
Number of teeth of drive side pulley: 20
Number of teeth of driven side pulley: 60
Speed: 3000 rpm
Tension (N): 160N
Test time: 24 H

* Problems of generic products on the market

Precautions

There may be no surface treatment in the shaft hole.

The positions of keyway and tooth are not fixed.

Example of Use

Example drawing of a workpiece reversal transfer mechanism designed using MISUMI 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.
At this time, the clamping mechanism rotates 180 degrees and does not change the direction of the workpiece relative to the conveying direction at the same time during transfer.

■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)

Usage Method

Usage Method Example Drawing	Usage Method of Timing Wheel and Timing Belt
	①Driving The driven wheel is driven by the driving wheel for transmission
	②Linear 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
	③Conveyance Plates are conveyed by two timing toothed belts
	④Traction transmission Workpieces are clamped and transmitted by the belt
