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

■Timing Pulley 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.

5M Tooth Profile	MISUMI Economy series (Good engagement)	Products circulating on the market *
Engagement of Timing Pulley and Timing Belt
Clearance	Small	Large
Positioning Accuracy	Height	Low

* Problems of generic Timing Pulley products in the market

■Rotation Stability of MISUMI Economy series Idlers

・MISUMI economy series idler uses MISUMI Economy series bearing with stabler quality and lower noise

・The tooth surface runout control of the Economy series idler is consistent with the standard Timing Pulley product, and the belt drive is smoother.

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 of Timing Pulley 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

Example drawing of a belt tension device designed using MISUMI timing belt idler

■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.
