Timing belts, (also accepted as toothed, notch, cog, or ancillary belts) are a absolute alteration belt and can clue about movement. These belts accept teeth that fit into a analogous asperous pulley. When accurately tensioned, they accept no slippage, run at connected speed, and are generally acclimated to alteration absolute motion for indexing or timing purposes (hence their name). They are generally acclimated in lieu of chains or gears, so there is beneath babble and a lubrication ablution is not necessary. Camshafts of automobiles, miniature timing systems, and stepper motors generally advance these belts. Timing belts charge the atomic astriction of all belts, and are a part of the a lot of efficient. They can buck up to 200 hp (150 kW) at speeds of 16,000 ft/min.

Timing belts with a circling account tooth architecture are available. The circling account tooth architecture forms a chevron arrangement and causes the teeth to appoint progressively. The chevron arrangement architecture is self-aligning. The chevron arrangement architecture does not accomplish the babble that some timing belts accomplish at assertive speeds, and is added able at appointment ability (up to 98%).

Disadvantages cover a almost top acquirement cost, the charge for distinctively bogus asperous pulleys, beneath aegis from overloading and jamming, and the abridgement of clamp action.

A timing belt is a asperous belt that connects the engine crankshaft to the camshaft .

A timing belt synchronizes the camshaft to the crankshaft position, so the valves will accessible and abutting at the able timing in affiliation to the position of the pistons. The camshaft rotates at absolutely 1/2 acceleration of the crankshaft; acceptation two revolutions of the crankshaft are according to one anarchy of the camshaft.

In some engines a timing belt can aswell drive added apparatus such as a baptize pump, antithesis shaft, average shaft, bang pump and an oil pump. A antithesis shaft, an average shaft and an bang pump accept to aswell be synchronised with a crankshaft.

To plan appropriately a timing belt needs to be beneath assertive astriction that is controlled by a timing belt tensioner. Some earlier cars accept an adjustable timing belt tensioner that accept to be re-adjusted if thetiming belt gets loose. A lot of of the newer cars accept an automated timing belt tensioner that doesn't charge any adjustment. If the timing belt gets loose, it may skip a tooth and the able timing will be lost.

When a Timing Belt China is replaced, it's actual important to set the timing properly. Before a a newtiming belt is installed, the crankshaft, the camshaft and added apparatus synchronised with a crankshaft accept to be accumbent in a assertive way. A adjustment chiral has able instructions and a diagram with timing marks. Improperly set timing will could cause a array of problems such as abridgement of power, vibration, misfiring, etc.
