What is HTD pulley?

High Torque Drive (HTD) timing pulleys The material used for smaller pulleys is Aluminium, medium sizes are in Steel, larger sizes in Cast Iron, all featuring flanges made from Steel; see individual catalogue pages for specific materials and dimensions. HTD, CXP and CXA belts are all designed to run on these pulleys.

What is HTD in 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 is pulley timing measured?

To quickly calculate the Outside Diameter (O.D.) in inches of any 8mm pitch timing belt pulley divide the number of teeth on the pulley by ten (10). For example an 80 tooth pulley would have an 8” Outside Diameter (O.D.) (80 teeth / 10) or a 33 tooth pulley would have a 3.3” Outside Diameter (O.D.) (33 teeth / 10).

What does HTD stand for?

HTD

Acronym	Definition
HTD	Highway Traffic Division
HTD	Hold ‘Till Drop (investing strategy)
HTD	Happiness through Drinking (band)
HTD	Home To Duty (mileage allowance)

What is rubber timing belt?

Also known as timing chain or cam belt, a rubber timing belt is an integral part of an internal combustion engine which controls the timing of the engine’s valves. Instead of timing belts, some engines use timing gears. The term “timing belt” is also used to refer any flat belt with integral teeth.

Can a belt & pulley system have teeth?

Normal power transmission belts and pulleys are smooth, so the belt can occasionally slip off track (one shaft would be turning while the other remains still). On the other hand, timing belts and pulleys have teeth, which lock the rotation of the shafts and prevent misalignment.
