1. Structural design and performance advantagesSimple manufacturing process:External spline shafts are usually composed of a central shaft, external splines and internal splines. This structure makes its manufacturing process relatively simple and easy to process and manufacture.High precision and high reliability:The position of the External Spline Hollow Shaft in the sleeve is very precise, which can ensure a high degree of fit between the shaft and the sleeve, thereby better eliminating the clearance during the transmission process and improving the precision of the machine.At the same time, the transmission method of the external spline shaft relies on the interlocking spline connection, which has a higher interlocking effect than the direct key shaft, and the transmission force is more stable. It can effectively prevent transmission slippage and other faults, thereby improving the reliability of the machine.Strong load-bearing capacity:The external spline shaft has a good load-bearing capacity under the transmission torque and can withstand certain lateral and axial loads, which makes it have significant advantages in occasions where it needs to withstand large torque and transmit high power.2. Transmission efficiency and energy-saving advantagesHigh transmission efficiency:The transmission efficiency of the external spline shaft is higher than that of the ordinary direct key shaft, because the spline matching effect is more precise and stable, and the torque transmission is more uniform, thereby reducing the loss of transmission efficiency. This high efficiency is of great significance to improving the overall operating efficiency of mechanical equipment and reducing energy consumption.3. Wide applicationWide application fields:External spline shafts are widely used in many fields due to their excellent performance, such as automation equipment, robots, CNC machine tools, wind turbines, high-speed railway vehicles and agricultural machinery. In these fields, external spline shafts are used to transmit high power and high torque, ensuring the normal operation and efficient production of equipment.4. Other advantagesCustomizability:External spline shafts can be customized according to specific application requirements, such as adjusting the size, shape and number of splines, etc., to meet the special requirements of different mechanical equipment for transmission components.Back-off groove design:In some high-speed bearing applications, back-off grooves are generally set on external spline shafts to reduce motion friction. This design helps improve the performance of the shaft, reduce motion friction, and increase the shear stiffness of the shaft. However, whether the backing groove needs to be set needs to be determined according to the actual application situation.The use of external spline hollow shafts has the advantages of simple manufacturing process, high precision and high reliability, strong load-bearing capacity, high transmission efficiency and wide application. These advantages make external spline hollow shafts widely used and recognized in mechanical equipment.
