3. Introduction of Splined coupling

Definition:

The spline connection consists of an inner spline and an outer spline.Both the inner and outer splines are multi-tooth parts. The spline on the inner cylinder surface is the inner spline, and the spline on the outer cylinder surface is the outer spline.Obviously, spline joint is the number of flat joint development.

Usage Features:

Due to the different structural forms and manufacturing processes, compared with flat key connection, spline connection has the following characteristics in terms of strength, technology and use:

Because more teeth and grooves are directly and uniformly produced on the shaft and hub hole, the connection force is more uniform;

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.

The number of teeth is more, the total contact area is larger, so it can bear a larger load;

The neutral of the parts on the shaft and the shaft is good, which is very important for high-speed and precision machines.

Good guidance, which is very important for dynamic connection;

The machining precision and joint quality can be improved by grinding method.

4. Heat treatment

As we all know, heat treatment is very important in the screw production process. In order to ensure the quality of products, Joiner has purchased professional heat treatment equipment to produce, so that we can control the construction process by ourselves.
