Why can't shaft and hole retainers be interchangeable?

The shaft retaining ring is usually installed on the groove shaft and is used to fix the axial movement of the parts. The main function is to prevent the axial movement of the bearing in the work and maintain the smooth operation of the equipment. Besides. Shaft retaining ring has the characteristics of simple structure, low cost, convenient installation and so on. The retaining ring for the hole is installed in the round hole and is used to fix the axial movement of the parts. The main function is similar to that of the shaft retaining ring, which is also used to achieve axial positioning and prevent the parts from moving in the axial direction.

There are significant differences in structure between shaft and hole retainers, which is one of the fundamental reasons why the two cannot be interchangeable. The shaft retaining ring is usually installed on the groove shaft. During installation, the pliers beak needs to be inserted into the pliers hole of the retaining ring, the retaining ring is expanded, and then placed on the pre-processed shaft groove. This installation method requires that the shaft retaining ring has a certain elastic deformation ability, so that it can be successfully stuck in the shaft groove. A stop ring for a hole is installed in a round hole. Insert the pliers nozzle into the clamp hole of the stop ring, clamp the stop ring, and then place the stop ring in the slot of the pre-processed round hole. Compared with the shaft stopper, the installation of the hole stopper is simpler, but it also requires special tools to operate. In addition, the reference of the two in the selection is different, the inner diameter of the shaft stopper in use is smaller than that of the assembly shaft diameter; The outer diameter of the hole stopper in use should be slightly larger than the diameter of the assembly round hole.

Shaft retaining ring and hole retaining ring are widely used in various mechanical equipment and components. However, the shaft retaining ring can effectively prevent the bearing or other parts from moving in the axial direction to ensure the normal operation of the equipment and the stable work of the parts. The retaining ring for the hole can effectively prevent the parts from moving in the axial direction and improve the stability and reliability of the equipment.

In short, the shaft retaining ring and the hole retaining ring are different in structure, installation mode and application scenario, so the two cannot be used interchangeably. It is recommended that when selecting and installing the stop ring, it is necessary to follow the actual situation and principles, and pay attention to related matters to ensure the performance and reliability of the equipment.
