Tungsten carbide spline hob spline joint consists of internal spline and external spline, which are both multitooth parts. The spline on the internal cylinder surface is called internal spline, while that on the external cylinder surface is called external spline.
Due to the differences in structure and manufacturing technique, tungsten carbide spline hob spline joint, compared to flat key joint, has characteristics in intensity, technique, and usage as follows:
I. Its joint force is more uniform due to its larger number of teeth and grooves produced directly and uniformly on the shaft and hub bore.
II. It has good guidance quality, which is very important to movable connection.
III. It has larger number of teeth and larger total contact area, and thus can withstand larger load.
IV. It has good coaxiality between shaft parts and the shaft, which is essential to high-speed and sophisticated machines.
V. It has shallow grooves, so the stress concentration is smaller in the teeth root and the intensity of shaft and hub is less reduced.
VI. The machining precision and joint quality can be improved through grinding.
VII. Its manufacturing technique is more complicated and sometimes special equipment will be needed, so that the cost is relatively higher.
