Frequently Asked Questions (FAQs)
1. What is a timing pulley flange?
Flanges are used to keep timing belts operating on their pulleys – they are designed to secure the lateral guidance of the timing belt. To prevent the belt jumping out of the pulley, one flange must be placed on each side of the belt, at least.
2. How does a timing pulley work?
Like traditional pulley systems, timing belt pulleys are driven by frictional forces between the belt and pulley surfaces. The teeth or pockets on the outside of the pulley are not used for power transmission. Rather, they engage the pulley belt, assisting with timing and averting misalignment.
3. What is HTD timing pulley?
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.
