AVTEC is now setting benchmarks in the manufacture of high-precision engine

A shaft is a cylindrical rotating rod used for transmitting the power in a machine. It basically delivers the power from the engine to other parts of the automobile before reaching the wheels. Generally, shaft is made up of mild steel or alloy steel. The gear is mounted on the shaft at required position.

Types of gears and shafts:

The four important type of gears are spur gears, helical gears, bevel gears, worm gears. Among this, spur gear is the most commonly used gear type in which the teeth are straight and parallel to shaft. In helical gear, teeth are twisted and slanting to the gear axis. Bevel gear has the axes of two shafts intersect and the tooth of the gears are conically shaped. The teeth of the worm gear is cut on an angle to be driven by a worm. Shafts are classified mainly into two types namely transmission shaft and machine shaft. Counter shafts and line shafts are some of the transmission shafts while crankshaft is a machine shaft.

Requirements of gears and shafts:

•        They must be completely rust proof.

•        Precise design must be ensured for a fine finish.

•        They should be easy to fix.

•        Strength and stiffness should be mainly considered during the design of gears and shafts.
