From tractors to heavy machinery, variable speed pulleys are used in a huge variety of applications. But how do variable speed pulleys work?

A critical component of power transmission systems is a worm gear speed reducer, also referred to as a right-angle gear box or a worm gear reducer. For compact applications with space limitation, miniature worm gearboxes can provide reliable solutions.

Torque's HTD timing pulleys are precision, injection molded and glass reinforced to offer efficient power transmission without slip or backlash.

With the greatest speed reduction in the smallest form factor, worm gearboxes are popular speed reducer solutions.

Typically found in lathes, light-duty milling machines, drills, and other power tools plastic or nylon molded v-belt pulleys are designed to be excellent solutions for low and fractional horsepower drives.  And while standard design v-belt pulleys are appropriate for most applications, there are situations where a custom v-belt pulley is necessary.

Multi-ribbed pulleys are molded to tight tolerances to keep concentricity nearly perfect and are found in a number of industries and applications.

A critical component of power transmission systems is a right-angle worm gear speed reducer, also referred to as a right-angle gear box or a worm gear reducer. 

Carter Day, a Minnesota-based manufacturer of agricultural equipment, produces a particular grain dryer that utilized a 14.4 inch, diameter, 8mm HTD timing pulley to rotate the dryer. 

Especially designed for low and fractional horsepower drives, v belt pulley construction material plays a significant part in the function of the pulley.

What specifications do you need know about your multi ribbed pulley before you order? What is going to impact the cost of your pulley? Is a custom solution best or will a standard option work for your application? These are just a few of the question you might ask when selecting your multi ribbed pulley supplier.
