Spline shaft is a kind of mechanical transmission, the same function as flat key, woodruff key and taper key, all used in transferring mechanical torque.There are lengthways keyways on the outside of the shaft, the rotating parts on the shaft also have corresponding keyways.They can keep the same rotation with the shaft. As they rotate, some can also slide lengthways on the shaft, like gearbox shift gears. Spline shafts are divided into two main kinds: rectangle spline shafts and involute spline shafts.The rectangle spline shafts are used in wide applications.On the contrary, the involute spline shafts are used in the connection with large size,load and high centering accuracy requirements.The rectangle spline shafts are usually used in aircraft, automobile, tractor, machine tool manufacturing, agricultural machinery and general mechanical transmission devices.Due to the rectangle spline shaft multi - tooth work , it has high load capacity, a good effect to the neutral and guidance.The feature of its shallower root makes it a low stress concentration.Besides the strength reduction of spline shaft’s shaft and hub is small, it’s easy to process and higher precision can be obtained by grinding method.Spline shafts are used in the connection with large size,load and high centering accuracy requirements. Features: the tooth profile is involute, there is radial force on the tooth when loaded which can center automatically, making each tooth forced averagely with high strength and long service.The process is the same as gear which can be easy to achieve high precision and interchangeability. Material: 45steel 40Cr
