Why are HTD teeth used in timing belts?
The high-performance profile HTD (High Torque Drive) has a round tooth for a good tooth engagement behaviour and optimized power and tension distribution (profile according draft ISO/F DIS 13050). The HTD-tooth belts offer a high degree of protection against skipping and is therefore often used in positioning and timing applications.
What are the different types of timing belts?
Timing belts are available in two sizes: in metric (millimetres) and imperial (inches) dimensions. The profile of the inner teeth of the belt which goes over the outer teeth of the pulley is the second most important factor. The most common forms are the trapezoidal and round tooth shape.
Which is the best belt for apex Dyna?
Of the range of metric round tooth shape belts, Apex Dynamics can offer pulleys to suit: The high-performance profile HTD (High Torque Drive) has a round tooth for a good tooth engagement behaviour and optimized power and tension distribution (profile according draft ISO/F DIS 13050).
Why are timing belts used instead of gear drives?
The use of a timing belt or chain instead of a gear drive enables engine designers to place the camshaft (s) further from the crankshaft, and in engines, with multiple camshafts a timing belt or chain also enables the camshafts to be placed further from each other.
What happens if your timing belt is broken?
The timing on the engine must be set exactly, or the valves and the pistons may collide, resulting in very expensive engine repairs. If your timing belt is broken, then make sure valve damage was not done before proceeding with the belt replacement.
How often do you need to change timing belt?
Available for a few dollars at any auto parts store, you’ll likely need to change yours every 90,000 to 120,000 miles (140,000 to 190,000 km), depending on your engine. Gather the information about your vehicle. You will need to know the make, model, and year model of the vehicle, as well as the engine type and size.
What does the timing belt on a Cosworth BDR do?
Cosworth BDR engine, with toothed cambelt and pulleys. A timing belt, timing chain or cambelt is a part of an internal combustion engine that synchronizes the rotation of the crankshaft and the camshaft(s) so that the engine’s valves open and close at the proper times during each cylinder’s intake and exhaust strokes.
