A Toothed Pulley: What Is It?

The kind of pulley used with a cog belt is a toothed pulley. The toothed pulley poleas dentadas resembles any other pulley with cogs or teeth machined into the outside perimeter in place of the more typical deep V associated with a conventional V type fan belt. The toothed pulley depends on the teeth’s driving power rather than the tightness and friction provided by a V belt. The toothed pulley is available in two typical tooth types, a Gilmore style and a high torque drive (HTD) design, and is frequently used in automobile and equipment applications. The HTD tooth is a deeper and rounder version of the pulley cut compared to the flat and square Gilmore tooth.

An example of a pulley is a toothed pulley, which is a mechanical traction device used to transmit a force to a transmission system that also includes other components like chains, belts, and pinions or gears. Similar to this, pulleys come in two varieties: variators and grooved. Although the form of its teeth differs from those of a gear, this kind of toothed pulley is fairly similar to one. They are also known by other names, such synchronic. There is no set rule that dictates how it should be referred to in each situation, but it is important to be familiar with both nomenclatures.

Belts are frequently the best option for driving or powering a machine or component. When compared to a chain or gear drive, this is because the reciprocating weight is less. The gadget needs a toothed pulley to drive a toothed belt. Due to their thin structure, toothed belts are favored over other belts of a comparable size. While offering similar or more strength, the thin rubber belt does not retain heat in the same way as a thick rubber belt does.

Due to the whining sound it creates when moving over a toothed pulley’s surface, the Gilmore-type belt is frequently chosen in high-performance applications. Due to the well-known sound a supercharger with a Gilmore belt generates on a performance engine, the sound is sometimes referred to as a blower whine; however, the sound is really produced by the air trapped beneath the belt, not the belt or toothed pulley. Some pulleys are drilled to provide a tiny hole in each groove or tooth, allowing the trapped air to escape and significantly reducing noise.

Measuring the fit of a toothed belt is much different than measuring a V-type belt. A V-style belt is sized by measuring the pulleys at the depth of the V. The toothed pulley is measured around the flat side of the pulleys to arrive at a belt size.
