Camshaft drive

作者: Release Date: 2017-02-16 Author: Click:

Common transmission methods between camshaft and crankshaft include gear transmission, chain transmission and toothed belt transmission. Most of the transmission between the lower camshaft and the middle camshaft and the crankshaft use cylindrical timing gears. Generally, only a pair of gears are required from the crankshaft to the camshaft. If the transmission gear diameter is too large, an additional middle Idler. In order to smooth the meshing and reduce the working noise, most of the timing gears use helical gears.

Chain drive is common between overhead camshaft and crankshaft, but its working reliability and durability are not as good as gear drive. Toothed belts are widely used instead of drive chains on high-speed engines, but chain drives are still used on some high-power engines. Toothed tape has the characteristics of low noise, reliable work and low cost. For double overhead camshafts, the exhaust camshaft is generally driven by the crankshaft through timing toothed belt or chain, and the intake camshaft is driven by the exhaust camshaft through a metal chain, or both the intake camshaft and exhaust camshaft Driven by crankshaft through toothed tape or chain.
