Mastering the Mechanics: An In-depth Look at Toothed Pulleys and Timing Belts

A toothed belt, also known as a timing belt, cogged belt, cog belt, or synchronous belt, is an incredibly versatile tool. It's equipped with teeth that are moulded onto its inner surface, designed to run over matching toothed pulleys or sprockets. These are integral components in various mechanical devices where high-power transmission is necessary.

Toothed Belts in Common Mechanical Devices

Toothed belts are not just found in heavy machinery but also in everyday devices such as sewing machines and photocopiers. A significant use of toothed belts is as the timing belt used to drive the camshafts within an automobile or motorcycle engine.

Why Choose Toothed Belts?

As toothed belts can deliver more power than a friction-drive belt, they are used for high-power transmissions. These include the primary drive of some motorcycles, notably later Harley-Davidsons, and the supercharger used for dragsters.

Microlight Aircraft and Toothed Belts

Microlight aircraft powered by high-speed two-stroke engines like the Rotax 532 use toothed belt reduction drives. This allows the use of a quieter, more efficient slow-speed propeller. Some amateur-built airplanes powered by automotive engines also use cog belt reduction drive units.

The Uniqueness of Tooth Pulleys

A tooth has some teeth, setting it apart from a flat belt pulley which doesn't have any teeth. The tooth pulley is used when accurate transmission of the torque is needed. Flat belt pulleys or V-belt pulleys cannot deliver 100% accurate transmission of the torque as there's always some (albeit minimal) slipping between the pulley and belt.

The WLY Toothed Pulleys and Timing Belts

WLY specializes in engagement transmission pulleys. Our products are of high quality and unique, hard-to-process designs are available as made-to-order products. We offer a wide lineup, including Fit Fores and keyless locking device types. Materials such as sintering, die cast, and plastic are also available.

Moreover, timing pulleys for competitor tooth profiles are also obtainable. Our pulleys are compatible with JIS, ISO, and DIN standard tooth profiles and special tooth profiles.

N Type Lock Pulleys

Our N Type Lock Pulleys can be locked easily with a single nut. Shaft diameters offered from 7mm make them ideal for small shaft locking. Lock pulleys can be fixed at a specific shaft or phasing position temporarily by manually locking the nut and stopping the rotation of the pulley body. The nut is then tightened to a specified locking torque with a torque wrench to lock in place.
