1.Static pressure method:
This method is based on the need of pressing force on the hub axle assembly of different sizes, with clamp, Jack, a manual or mechanical press, static pressure method is usually used in the conical shaft hole. Due to the static pressure in the law of pressure machinery to receive the limit, in a large surplus, it is difficult to exert a lot of force. At the same time, the indentation process will cut off between the hub and the shaft with small convex peak surface uneven, the surface is damaged. Therefore, this method is not generally used.
2.Dynamic pressure method :
Pump assembly this method refers to the use of impact tools or machinery to complete the assembly process on the wheel shaft, generally used in the wheel and shaft with the transition to make the transition with or too little. Methods the hand hammer usually assembly method is put, wood, lead or other soft material as a buffer in the hub end, rely on the impact hammer, the hub type. This method of using cast iron, quenched steel, cast alloy and other brittle materials made of wheel, there is the risk of local damage, should not be used. This method can also damage the mating surfaces, so it is often used in low speed and small couplings.
