Industry Solutions for Shaft and Bore Retaining Rings

The elastic retaining ring is a widely used type. There are two main categories: shaft and Hole. How are each of them? Who is responsible for what aspect, and what is it? Here's a look!

The elastic retaining ring is divided into the shaft. A hole with different structural characteristics: The shaft with the elastic retaining ring is a kind of installation in the shaft groove, used as the positioning and fixation of the shaft end parts, and can withstand severe vibration and shock load but needs to take measures to prevent loosening and installation of the positioning; Hole with the elastic retaining ring is installed in the Hole, used as a fixed part of the axial movement, the outer diameter of this retaining ring than the assembly of the diameter of the circle hole is slightly larger.

The elastic retaining ring is a kind of industrial accessory that can play the functions of support, buffer, brake, height adjustment, and angle adjustment. A shaft with an elastic retaining ring selection of the inner diameter is slightly smaller than the assembly of the shaft diameter. A Hole with an elastic retaining ring selects the outer diameter of the retaining ring, then the assembly of the diameter of the Hole is somewhat more significant; the retaining ring mainly plays a role in axial fixation, which is conical plus retaining ring fixed with a high degree of centering. Elastic retaining and ordinary stamping retaining rings are more secure and easier to install and dismantle. A typical regular stamped retaining ring installation requires maintaining ring removal pliers. The jaws of the removal pliers are inserted into the jaws of the stamped retainer "lugs," and the stamped retainer is expanded along the shaft surface or pressed into a groove in the housing. When installing or removing large common stamped retainers, the stamped retainer may fly out of the pliers, posing a safety hazard.

Elastic retaining ring installation method:

1. Most of them are installed with elastic retaining ring installation pliers;

2. Simple installation aids;

3. Automatic, elastic retaining ring installation machine.

The disadvantages of these installation methods:

1. Manual installation: if the force is not uniform, plastic deformation of the elastic retaining ring will lead to the failure of the elastic retaining ring;

2. For the structure of complex parts can not be positioned, and the production efficiency is also lower;

3. Simple installation aids are only applicable to the parts to be installed, generally not universal, with limitations;

4. The automatic, elastic retaining ring installation machine has a complex structure and high cost.

Elastic retaining ring for shaft

The shaft elastic retaining ring is installed in the groove shaft and used to fix the axial movement of the parts. The inner diameter of this kind of retaining ring is slightly smaller than the diameter of the assembly shaft. When installing, it is necessary to use the spring pliers, insert the jaws into the Hole of the retaining ring, expand the retaining ring, and then put it into the pre-processed shaft groove. Conventional packaging to oil paper or plastic for a batch of packaging, the surface is generally based on phosphate blackening, commonly known as an external card. Shaft retaining ring production needs to pay attention to several aspects; first, the surface is flat; hardness and elasticity of the qualified; third, there can be no edge burrs.

Hole with elastic retaining ring

Installed in the Hole used to fix the axial movement of the parts, the outer diameter of such a retaining ring is slightly larger than the diameter of the assembly hole. Installation must use spring pliers inserted into the jaws of the retaining ring hole, clamping the retaining ring to put it into the pre-processed round hole groove.
