Characteristics of elastic retaining rings for holes

A hole retaining ring is a fixed part of the axial movement of the tool installed in the hole and used to improve the axial movement of the parts; the outer diameter of such a retaining ring is slightly larger than the diameter of the assembly hole. When installing, it is necessary to use the spring pliers, insert the jaws into the hole of the retaining ring, and then clamp the retaining ring to put it into the pre-processed round hole groove. A hole elastic retaining ring is a simple and practical axial connection element commonly used in mechanical equipment, shaft, and hole connection. Its main features are high elasticity and wear resistance, which can alleviate the impact of axial and radial forces within a specific range and reduce the impact and vibration in motion. At the same time, it can also effectively prevent the loosening or vibration between the shaft and the hole to ensure the regular operation of mechanical equipment.

The role of the elastic retaining ring in the hole

The role of an elastic retaining ring for the hole is mainly to connect the shaft and hole and play the role of buffer and stabilization in the movement process. When the mechanical equipment is operated, the axial force and radial force will impact the shaft and hole, resulting in the gap between the shaft and hole producing loose or vibration, thus affecting the regular operation of mechanical equipment. Using elastic retaining rings for holes can effectively reduce these adverse effects and extend the service life of mechanical equipment. Advantages of using hole retaining ring:

1. Prevent the loosening of bolts caused by vibration so that problems related to the loosening of fasteners no longer occur;

2. Ensure that the clamping force of the connecting parts is still maintained under solid vibration, which is superior to the fasteners that rely on friction to self-lock;

3. Easy to install and dismantle without exceptional installation work;

4. The elastic retaining ring for holes has durability;

5. Temperature changes will not loosen the connection;

6. Elastic retaining rings for holes can be reused.

Selection and installation of the elastic retaining ring for the hole

When selecting the elastic retaining ring for the hole, it is necessary to determine the appropriate model and specification according to the diameter of the shaft and hole, rotational speed, load, and other parameters. Generally speaking, the installation order of the elastic retaining ring for the hole is to install on the shaft first, insert the rod into the hole, and then push the retaining ring to the end. When installing, attention should be paid to the sealing direction of the retaining ring to avoid reverse installation or wrong connection. At the same time, attention should also be paid to the amount of stretching of the retaining ring during installation, which should be adjusted to the appropriate position according to the actual situation. Using elastic retaining rings for holes in mechanical equipment can effectively prevent loosening or vibration between the shaft and the hole and extend the service life of mechanical equipment.
