What is a timing gear, such as a camshaft timing gear, and what is its function?
Function of timing gear: It can play the role of time scale positioning when relevant control functions are completed in mechanical devices.
There are three transmission modes of timing gear: chain transmission, toothed belt transmission and gear transmission. Spur gear and spur gear of automobile engine are driven by toothed belt, which has the advantages of simple structure, low noise, stable operation, high transmission precision and good synchronization, but its strength is low, and it is easy to age, stretch, deform or break after long-term use, which is not convenient to observe its working condition.
The time and state of valve action must be consistent with the state and time of piston movement, but crankshaft and camshaft are not on the same axis, and there must be a transmission system between them. This transmission system is completed by two gears and a chain or belt, so these two gears are called timing gears.
