The transmission shaft is generally provided with a sliding spline composed of a sliding fork and a spline shaft to realize the change of transmission length. In order to reduce the axial sliding resistance and wear of the sliding spline, the spline teeth are sometimes phosphatized or sprayed with nylon layer. Some in the spline slot into the needle, roller or ball and other rolling components, rolling friction instead of sliding friction, improve transmission efficiency. But this kind of structure is more complex, the cost is higher. Sometimes for serious impact load of the transmission, but also the use of flexible shaft. Spline on the transmission shaft should be lubrication and dust prevention measures, spline teeth and keyway clearance should not be too large, and should be assembled according to the corresponding mark, so as not to damage the transmission shaft assembly wrong dynamic balance.

The length and Angle of the transmission shaft and their variation range are determined by the automobile general layout design. When the length of the transmission shaft is at the maximum, the spline sleeve and the shaft should have enough fit length. And in the length of the minimum not top dead. The Angle of the drive shaft directly affects the life of the universal joint cross shaft and needle roller bearing, the efficiency of the universal drive and the unevenness of the cross shaft rotation.

The drive shaft is used with various main engine products, and the working environment is complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, salt water, radiation and so on. For high temperature, low temperature, oil, acid, alkali medium work quality, should not choose to general rubber flexible coupling for elastic element material, should choose metal flexible coupling, such as diaphragm coupling, snake spring coupling.
