How Do Timing Belts Work?

You may have heard of timing belts, but how do they work?

With competitive price and timely delivery, SBT sincerely hope to be your supplier and partner.

According to Medium:

'Timing belts are essentially reinforced rubber bands that co-ordinate the rotation of the crankshaft and camshaft in your car's internal combustion engine. They control engine operation, and some power the water pump too. Timing belts are usually manufactured from high-quality rubber and nylon-reinforced cords.

But how exactly do timing belts work?

How Timing Belts Work

'The timing belt's job is cyclic. Its primary function is to rotate the camshaft pulley, synchronising this pulley with the crankshaft pulley. Some models have two camshaft pulleys. The timing belt synchronises the valves and pistons so that they push cams on the camshaft at the right times. This process is comparable to pedalling a bicycle. The cams must reach the top of the cycle before the valves and pistons push them down again.

'The inner part of the belt contains teeth that correspond to the gears. The teeth create friction as the timing belt comes into contact with the crankshaft and camshaft sprockets. If the teeth are damaged, the timing belt can pull the crankshaft and camshaft out of synchronisation. This throws the valve and piston timing, which can destroy the valves and pistons. The damage is often even worse if you have a timing chain.

'Each timing belt also needs a tensioner to maintain pressure on the timing belt. The tensioner may be spring-loaded, oil-pressure-activated or set manually. Tensioners ensure that the timing belt delivers enough tension to move all of the pulleys that drive engine components.

We know that a cambelt is a vital component of internal combustion engines. However, what does a timing belt do, exactly, and how do different types of timing belts play similarly crucial roles in a variety of other systems and mechanisms?

Timing belts are typically ridged with a circumference of protruding rubber teeth, and in an engine, it's these teeth that enable the loop of timing belt material to turn the camshafts via the crankshaft as the various parts rotate at a consistent ratio of speed. Together, these components are thus responsible for opening and closing the intake and exhaust valves in an engine.

When a cambelt is in good working order and functioning correctly, the opening and closing of these valves are maintained at an optimal rhythm to match the up-and-down motion of pistons within the engine's cylinders, allowing for the smooth and efficient functioning of the entire apparatus as the engine cycles through each of its various strokes (usually intake, compression, power, and exhaust).

In the case of a broken or failing timing belt, engine valves can be left stuck in an open position. This risks serious damage to the mechanism of so-called interference engines if they can be struck repeatedly by the pistons. Non-interference engines avoid this particular complication by keeping the valves and pistons separately confined. However, the engine will still be immobilised without a functioning cambelt installed.

As timing belts loop around a series of pulleys to connect up all the relevant engine components in sequence, they tend to rely on a number of tensioners to keep the ideal tension on the belt along its full length. These will usually need to be replaced along with new cambelts, as they're almost always roughly the same age as the main belt and have a similar expected lifespan.
