Temperature – extreme heat or extreme cold.Customary conditions that often impact pulley choice include: Does your working environment have specific food-safety requirements? Should the system be anti-static for electronic applications?Ĭonsider all environmental conditions that may impact the chosen timing belt pulley. Utlimately, selecting the proper timing belt pulley for your application begins with an environmental audit. How Do I Choose a Timing Belt Pulley? Environmental Considerations Finally, Timing Belt Pulleys drastically reduce operation noise as opposed to chains or gears. Furthermore, unlike many pulleys, belts and gears do not come in direct surface-to-surface contact, eliminating the need for constant lubrication. Prized for their reliability, these pulleys are known for minimal operation issues and strictly maintained system timing.
Due to their relatively low-cost, V-Belt Pulleys are a popular option. Named for tapered pulley sides that form a V-shaped groove, V-Belt Pulleysare a transmission belt that transmits the force of an engine to ancillary components, including alternators, hydraulic pumps, etc. As the name implies, Variable Speed Pulleys are designed to change rotating shaft speeds, increasing or decreasing revolutions per minute as needed. Unlike Multi-Ribbed Pulleys, Variable Speed Pulleys are commonly utilized in larger applications, such as heavy machinery. Designed for power in compact environments, Multi-Ribbed Pulleys are designed for higher torque in minimal space. Multi-Ribbed Pulleys are found in a multitude of applications, including fans, dryers, microwaves, and chair lifts. Multi-Ribbed, Variable Speed, and V-Belt Pulleys are among the most common options. In fact, depending on your specific applications, selecting another pulley may be ideal. Other OptionsĪs mentioned, timing belt pulleys are not the only variation available. Timing belt pulleys eliminate this concern as teeth or pockets keep the pulley firmly attached to the belt during operation. At times, the smooth belt can slip off the track, causing one shaft to turn while the other sits dormant. Most traditional power transmission belts and pulleys are smooth, without teeth or pockets. Timing belt pulleys are utilized when two shafts need to be precisely linked for homogeneous rotation. Rather, they engage the pulley belt, assisting with timing and averting misalignment. The teeth or pockets on the outside of the pulley are not used for power transmission. Like traditional pulley systems, timing belt pulleys are driven by frictional forces between the belt and pulley surfaces.
Timing Belt Pulleys DefinedĪ timing belt pulley is a specialized pulley system with teeth or pockets along the outside of the pulley body’s diameter. Finally, we provide an overview on selecting the best timing belt pulley option for your application. In the content below, we explore timing belt pulleys and discuss basic definitions, common uses, and pulley materials.
Timing belt pulleys are one of the most popular pulleys on the market, known for the unique ability to prevent misalignment and maintain accurate timing during operation. Due to the assortment of needs, multiple pulley variations have been created and manufactured according to each application. Both your hotel elevator and sewing machine utilize various pulleys to complete necessary functions. Pulleys are one of the most common pieces of equipment found in applications around the workplace and in the home.
