A gearbox, which is a mechanism for changing the rotational speed and torque from an engine, can fix or shift the ratio of the output shaft to the input shaft. The speed variator consists of speed-changing driving mechanism and operating mechanism, and some automobiles also have power output mechanism. Most of the transmission mechanisms are driven by common gears, and other transmission mechanisms are driven by planetary gears. Common gear transmission speed change mechanisms generally use slipping gears, synchronizers and the like.
The gearbox typically has a drive wheel and a drive shaft disposed therein and is coupled by a spline. The spline connection consists of an internal spline and an external spline. The inner spline and the outer spline are multi-tooth parts, the spline on the surface of the inner cylinder is an inner spline, and the spline on the surface of the outer cylinder is an outer spline. Obviously, spline coupling is a development in number of flat-key couplings. The spline is standard structure, and traditional spline connection, inside and outside spline are straight spline, and along with the increase of drive time, spline connection relation is unstable, can take place not hard up when serious, can't drive.
