2. Generally, there is no interference in spline connection, so the connected parts need to be fixed axially.
3. Spline is fast, simple and excellent, and the spline connection has high bearing capacity and good neutrality.
4. Splines are expensive to manufacture and need to be processed with special tools.
5. Splines have a large number of teeth and a large total contact area, so they can bear a great load.
6. Types of spline connection: According to different tooth shapes, splines can be divided into rectangular splines and involute splines, both of which have been standardized.
Extended data
Use of splines
1. Compared with Ping Jian connection, spline connection has the following characteristics in strength, technology and use due to different structural forms and manufacturing processes.
2. Because more teeth and grooves are directly and evenly made on the shaft and hub holes, the spline joint is subjected to more uniform force.
3. Because the groove is shallow, the stress concentration at the tooth root is small, and the strength of the shaft and hub is weakened less.
4, more teeth, large total contact area, so it can bear greater load; Good alignment between the parts on the shaft and the shaft is very important for high-speed and precise machines.
5, good guidance, which is very important for dynamic connection.
6. Grinding method can be used to improve machining accuracy and connection quality.
7. The manufacturing process is complicated, sometimes special equipment is needed, and the cost is high.
8. Applicable occasions: connections with high centering accuracy, large transmission torque or frequent slipping.
