The spline shaft is divided into two types: rectangular spline shaft and involute spline shaft. The spline shaft in the spline shaft is widely used, while the involute spline shaft is used for large loads and requires high centering accuracy. And the larger size of the connection.
Rectangular spline shafts are commonly used in aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery, and general mechanical transmissions. Due to the multi-tooth work of the rectangular spline shaft, the bearing capacity is high, neutrality and guidance are good, and its shallow tooth root can make its stress concentration small. In addition, the strength of the shaft and hub of the spline shaft is weakened, and the machining is more convenient. A higher accuracy can be obtained by the grinding method.
Involute spline shafts are used for large loads, high centering accuracy, and large-size connections. Its characteristics: tooth profile is involute, when loaded with radial force on the teeth, can play a self-centering role, so that the teeth are evenly distributed, high strength and long life, the same processing technology and gear, easy to obtain high accuracy and interchangeability.
