Frequently Asked Questions (FAQs)
1. What is HTD timing pulley?
HTD Taper Lock timing pulleys are the basic type of pulleys for HTD and RPP timing belts for Taper bush. They are made of steel or gray cast iron. The pulleys are mounted to the shafts using the Taper bushes.
2. What is taper lock pulley?
Taper lock bush pulley allows unskilled labor to achieve coupling of pulleys and shrink fit on shafts using just hexagon wrench. It has arrangement of longitudinal split tapered bushes and half-threaded holes that give easy, fast fitting and maximum grip.
3. How are pulleys and belts used to drive mechanisms?
Grooves on the pulleys and belts help them to grip and turn. Winches, treadmills and washing machines are examples of belt-driven mechanisms . Belts can be attached around different-sized pulleys to drive shafts to change speed. As with gears, the bigger the wheel, the slower the speed.
4. What are timing belt pulleys used for?
Timing belt pulleys are utilized when two shafts need to be precisely linked for homogeneous rotation. Most traditional power transmission belts and pulleys are smooth, without teeth or pockets. At times, the smooth belt can slip off the track, causing one shaft to turn while the other sits dormant.
