Product Overview

Usually, timing pulleys 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 and timing belts.

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 free-end toothed timing belt.)

Usage Method Example Drawing	Usage Method of Timing Wheel and Timing Belt
	③Conveyance (Plates are conveyed by two toothed timing belts)
	④Traction transmission (Workpieces are clamped and transmitted by the belt)

Shape S timing pulleys, suitable for MISUMI standard and economy series S specification belts.

Precautions

For Shaft Bore Specs. P (round hole+threaded hole) or N, the attached set screws are shipped in the same package (may drop in the packaging bag).

There is no threaded hole for Shaft Bore Specs. H (round hole).

There may be no surface treatment in the shaft bore.

For the N keyway 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

Equipment Name:
Workpiece Reversal Transfer Mechanism
Purpose:
Rotates the workpiece on the conveyor belt by 90 degrees and transfers it to the next process, using the transmission power of the timing pulley and the timing belt. 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.
Purpose of 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)
