What is HTD pulley?
Table of Contents
Posted by Torque Transmission. Torque’s HTD timing pulleys are precision, injection molded and glass reinforced to offer efficient power transmission without slip or backlash.
What is HTD timing belt?
HTD® Timing Belts feature a curvilinear tooth profile, which is a design advancement over the standard trapezoidal shaped belts. The curvilinear profile allows the belts to have a much larger contact area with the pulley, which improve performance.

How do you measure a pulley for a belt?
How to calculate a belt length?
- First, determine the diameter of the larger pulley. Measure the diameter of the larger pulley.
- Next, determine the diameter of the smaller pulley. Measure the diameter of the smaller pully.
- Next, measure the distance between pulleys.
- Finally, calculate the belt length.
What size belt do I need for a 42 inch waist?
How to Determine What Size Belt to Order

---|---|---|
41 | 45 | 46 or 47 |
42 | 46 | 47 or 48 |
43 | 47 | 48 or 49 |

What is HTD drive?

HTD stands for High Torque Drive and refers to a drive system utilizing belting that has a curvilinear tooth, improving on torque capacity over traditional timing and V belt drives. A HTD drives utilizes belts and belt “sprockets”, providing timing and synchronization accuracy.
What is GT2 timing belt?
GT2 timing belts are intended for lower load applications such as the first reduction in a gearbox, or motor to flywheel. GT2 belts use a smaller pitch than HTD belts, which means you can use larger reductions in those tight fit areas of your robot.
What is the pitch diameter of a pulley?
pitch diameter: Diameter of the pulley at the pitch line level of the belt used with this pulley. pitch circumference: Circumference of a circle with a diameter equal to the pitch diameter. effective diameter: Reference diameter of the pulley at the tip of the grooves, with the minimum specified transitional radius.
How do you pick a belt size?
The general rule for belt sizing is your men’s pant size plus two inches equals your belt size (i.e. if your pants size is 32, buy a belt size 34; if your pants size is a 34, buy a belt size 36; if your pants size is a 36, but a belt size 38, etc).
