Timing Belt Pulley
A Timing Belt Pulley is part of the timing belt system for an automobile. A timing belt is one way to control the opening and closing of engine valves by connecting the crankshaft to the camshaft of the vehicle. Generally, the timing belt does this by having teeth that lock into the teeth of the two gears for the crankshaft and camshaft.
A timing belt is one of several belts used in conventional cars and other vehicles. A serpentine belt is a belt that drives various other engine accessories off of the crankshaft. The serpentine belt can run an alternator, power steering pump, and air conditioning compressor. In some vehicles, these jobs are split between multiple belts, where a vehicle usually has only one timing belt pulley.
There are several advantages for selection of Timer Belt Pulley Drives :
Timer belt drives are positive grip devices. There is no chordal rise or fall of pitch line, no slippage and no belt creeps. This belt require no lubrication because there is no metal to metal contact and the noise level is low in normal speed range.
Cost is always and important advantage and the initial cost is usually the only expense involved. Thus, Timer belt drives are an economical means of power transmission.
Timer belts have a speed range from inches per hour to approximately 16.000 fpm. Small pitch belt can transmit positive motion while operating at high speed. Speed in excess of 8000 fpm are generally impractical for large pitch belts.
Power capacity of Timer belt drive ranges from subfractional to approximately 800 hp. The drive must be belted to transmit the power required by the highest load encountered.
Special functions, Many Timer belts drives are used for functional rather than power transmission application. Because they travel with predictable positive, nonslip, precision, designers have created a variety of devices. As example, anguler drive, triangular drive, squre drive, deflection drives, multi shaft drive, reversing drive, conveyor belt drive etc. Also tubing cut-off system, fabricating cartons, elevator conveyor for ball bearing, drive track for snow mobile etc.
