[0002] The propeller shaft, also known as the drive shaft or transmission axis, is an important component used to transmit power or torque in a car or other vehicle. The propeller shaft is usually made of metal and has a certain strength and rigidity to withstand the torque output by the engine and transmit it to the drive wheels.
[0003] During the production process of existing drive shafts, in order to meet the transmission requirements of subsequent drive shafts, it is necessary to open a corresponding keyway at the end of the drive shaft. However, during the slotting process, the drive shaft is usually clamped and fixed by clamping on both sides. When slotting, the cutter head will apply a certain thrust to the drive shaft following the moving direction, causing it to displace horizontally, which makes the drive shaft easily offset during the slotting process, thereby reducing the slotting accuracy.
