In the automotive industry, the timing belt is an important part of the engine. The belt drive is composed of an endless belt with an equidistant tooth profile on the inner peripheral surface and a wheel having a response fit. It combines the advantages of belt drive, chain drive and gear drive.
The timing belt is an important part of the engine air distribution system, through the connection with the crankshaft and with a certain transmission ratio to ensure that the inlet and exhaust time is accurate. The use of belts rather than gears is driven because the belt is small in noise, precise in transmission, small in size and easy to compensate. Obviously the life of the belt must be shorter than the metal gear, so the belt should be replaced regularly.
The timing of the timing belt is to maintain the "synchronous" operation at the moment when the engine is running, the stroke of the piston (up and down movement), the opening and closing of the valve (time) The Timing, that is, through the engine timing mechanism, so that each cylinder just to do: the piston just up to the top deadline, the valve just closed, spark plug just ignition.
The timing belt is a consumable product, and once the timing belt is broken, the camshaft does not operate according to the timing, which is likely to cause the valve and the piston to hit and cause serious damage, so the timing belt must be replaced regularly. With the increase in engine work time, the timing belt and timing belt accessories, such as tensioners, tensioners and pumps, etc. will wear or aging. Therefore, all equipped with a timing belt of the engine, in a specified period of time to regularly replace the Rubber Timing Belt and accessories.
