1、 Design principle of spline shaft

Spline shaft is a mechanical transmission component composed of a shaft and a key. A key is a connector inserted between a shaft and a hub, used to transmit torque. Spline shafts are generally used for small and medium power transmission devices and have good heat resistance and wear resistance.

The design principles of spline shafts include the following aspects:

1. Selection of spline shape: The spline shape includes circular, square, trapezoidal, etc. Choosing the appropriate spline shape can enable the spline shaft to transmit greater torque.

2. Calculation of spline size: The spline size of the spline shaft needs to be calculated based on the required torque and working conditions to ensure the bearing capacity and stability of the spline shaft.

3. The fit between the spline and the wheel hub: The fit between the spline and the wheel hub of the spline shaft needs to meet certain fitting requirements to ensure the stability and transmission efficiency of the spline shaft.

2、 Application scenarios of spline shafts

Spline shafts are widely used in various transmission devices, such as industrial machinery, automobiles, ships, aircraft, etc. Among them, the gearbox and drive shaft of the car both use spline shaft transmission.

The application scenarios of spline shafts include the following aspects:

1. High torque transmission: The spline shaft has good load-bearing capacity and wear resistance, making it suitable for high torque transmission systems.

2. High speed movement: The spline of the spline shaft fits tightly with the wheel hub, making it suitable for high-speed transmission systems.

3. Applications with high reliability requirements: The production accuracy of the spline shaft is high, the transmission efficiency is high, and it is suitable for applications with high reliability requirements.

3、 The manufacturing process of spline shaft

The production process of spline shaft includes the following steps:

1. Design a blueprint for the spline shaft, including the length, diameter, spline shape, and size of the shaft.

2. Make splines, cut suitable materials into spline shapes based on the dimensions of the shaft and hub, and process them to fit the dimensions of the shaft and hub.

3. Make the shaft and hub, and process them into the size and shape that match the spline according to the size and shape of the spline.

4. Insert the spline between the shaft and the hub, and adjust the position of the spline so that it does not deviate during transmission.

5. Assemble and debug the spline shaft, and check whether the transmission effect and stability of the spline shaft meet the requirements.
