Toothed pulleys

One of the most effective types of pulley is toothed pulley which works with the cog belt. A toothed pulley makes use of teeth or cogs around its perimeter in place of the deep V found on a V belt. With a V belt, tightness and friction provide the driving force instead of teeth.

Toothed pulleys are commonly used in machine and automotive designs. They are available in two types, a Gilmore style and a high torque drive (HTD). Typically, Gilmore teeth are square and rectangular with a very shallow cut in the pulley end, while HTD teeth have a deeper, semi-rounded tooth profile that allows more power to be applied without slipping the belt.

In many machines and applications, belts are mainly preferred to use for powering and running the machine and component. Since there is less reciprocating weight than in a chain or gear drive, which is possible to move easily. In order to improve the performance, the poleas dentadas is the best solution for this. Specific sized belts are preferred for toothed pulley which is been mainly manufactured for the thin construction style.  The thin belt does not hold heat while reciprocating frequently. And at the same time thick rubber belt does providing an equal and superior strength.

Gilmore belt is a suitable type of belt for high performance applications which is used to make winning noise when the motion is done on the surface of the toothed pulley. When a Gilmore belt-equipped supercharger is fitted to a performance engine, it causes a famous noise called a blower whine. However, the sound results from trapped air underneath the belt, not from the belt or poleas dentadas. A small hole may be drilled into each of the grooves or teeth of some pulleys to allow trapped air to escape, thereby reducing noise greatly. There is a huge difference in measuring fit for toothed belts and for V-type belts. The pulleys of a V-style belt are measured at the depth of the V. The pulleys of a toothed belt are measured around the flat side of the pulleys to get a belt size. Two toothed pulleys are also machined at an angle with opposing angles, which is called a pitch. An alternative to tightening the belt by forcing the pulleys apart is to use two differently-angled pulleys. The belt can attempt to slide off one pulley while the other toothed pulley slides it back in place.
