In drive shafts, a sliding spline typically consisting of a sliding fork and a splined shaft is usually provided.

The spline shaft has sufficient mating length with the axle; and it does not bottom out when the length is at its minimum. The size of the transmission shaft angle directly affects the service life of the universal joint cross shaft and needle roller bearing, the efficiency of the universal transmission, and the uneven rotation of the cross shaft.
To achieve changes in transmission length. In order to reduce the axial sliding resistance and wear of the sliding spline, the transmission shaft assembly is mainly composed of the transmission shaft and the spline shafts welded at both ends and the universal joint fork. The transmission shaft generally has a sliding spline composed of a sliding fork and a spline shaft. Sometimes, the spline teeth are phosphated or coated with a nylon layer; some have rolling elements such as needles, rollers, or balls placed in the spline grooves to replace sliding friction with rolling friction, improving transmission efficiency. However, this structure is more complex and the interest is higher. Sometimes, for transmissions with severe impact loads, elastic transmission shafts are also used. The splines on the transmission shaft should have lubrication and dust prevention measures. The gap between the spline teeth and the keyway should not be too large, and should be assembled according to the corresponding markings to avoid misassembly and damage to the dynamic balance of the transmission shaft assembly.
