What are the classifications of retaining rings?

What we are interested in is how to improve the performance of the spring. Breakthroughs in technology. Building the Lisheng brand for 100 years.

Self Locking Spiral retaining ring

The retaining ring is what we often call the circlip. It is used to prevent the movement of parts. It is widely used in the automotive, machinery and other industries. Let’s take a look at the classification of retaining rings.

 

Flat ring

A separable substantially flat washer whose inner or outer portion serves as a radial cylindrical roller outer or inner rib.

 

Bevel ring

A separable ring with an “L”-shaped cross-section, the outer part of which acts as the inner rib of the radial roller ball retaining ring.

 

Middle retaining ring

A separable ring in two or more rows of roller retaining rings that separates and guides each row of rollers. Note: A rib is a narrow shoulder parallel to the rolling direction and protruding from the raceway surface to support and guide the rolling elements and keep them in the retaining ring.

 

ID/OD locking ring

The ID/OD Locking Retaining Ring is a circlip that fits into both internal and external grooves to create a vandal-resistant concealed assembly. ID/OD Locking Rings are used in applications where two mating components are required to be secured to each other but free to rotate independently. The two components each feature a groove designed to lock the retaining ring on the ID and OD respectively; hence the term “ID/OD lock”. The retaining ring cannot be disassembled and neither can the two components, although it cannot be removed without damaging the retaining ring and the assembly.

Wire retaining clips for shaft

Split ring

Install the split ring on the test shaft, and then remove it to measure the inner diameter (d). The diameter of the test shaft shall be equal to this dimension of the groove diameter (d).

 

Self locking spiral retaining ring

A self-locking retaining ring is a custom retaining ring designed to help increase the rotational capacity of the retaining ring and is ideal for applications with high rotational capacity requirements. The self-locking function is achieved by a protrusion and a groove, which interlock to prevent expansion of the retaining ring. The protrusions fit perfectly into the grooves on the mating turns so that when the retaining ring is installed in the grooves, the protrusions snap into the grooves. This feature allows the retaining ring to function properly at speeds well beyond the rotational capability of standard circlips. Therefore, this self-locking function enables the retaining ring to operate at high speeds, withstand vibration, and accelerate operation, while absorbing a certain degree of shock load. Self-locking protrusions can be located on the outer diameter of the retaining ring (for outer circlips), the inner diameter (for inner circlips), or on the centerline.

 

Balanced spiral ring

A balance retaining ring is a custom retaining ring designed to help reduce the amount of residual unbalance in the retaining ring itself. By reducing the residual unbalance of the retaining ring, it helps to reduce the overall unbalance of the entire assembly. The balance retaining ring has a balancing function, and its static balancing function is comparable to that of a spring retaining ring. The retaining ring is provided with a series of grooves opposite the notched ends, enabling the center of gravity of the retaining ring to achieve static balance on its axis of rotation.

 

Gap wave spring retaining ring

The gap wave spring retaining ring is actually a kind of shaft retaining ring, which uses its elasticity and trumpet-shaped opening to press the retaining ring into the groove that is smaller than the nominal diameter of the shaft but not smaller than the inner diameter of the open retaining ring, and the side of the retaining ring passes through the hole. End face positioning to limit the axial displacement of the part

Retaining ring

The retaining ring is a retaining ring made of elastic material, generally made of spring steel, which has high hardness, strength and good elasticity after heat treatment. In order to prevent rust, the surface of the retaining ring usually needs to be electroplated (galvanized or plated with picks) or oxidized, but it is prone to hydrogen embrittlement fractures for electroplated products.

According to the function of use, the retaining ring can be divided into the retaining ring for holes and the retaining ring for the shaft; according to the manufacturing process of the retaining ring, it can be divided into strip cutting and forming retaining ring and wire winding forming retaining ring lock up.

 

The difference between circlip and spiral retaining ring:

There are big differences between the two in terms of appearance:

  1. The circlip usually has two process holes for the support of the circlip pliers, and there are two obvious protrusions at the process holes; while the spiral retaining ring has no protrusions.
  2. The double-layer spiral retaining ring is similar to the keychain, the difference is that there is a chamfer at the end of the retaining ring wire for blessing. Due to the addition of process holes, the circlip is easier to disassemble and assemble, but the protrusions at the installation process holes occupy a large space, and both the hole and the shaft circlip have the problem of taking up a large space.
  3. Compared with the circlip, the spiral retaining ring has no process holes, and the disassembly is not as convenient as the retaining ring, but the installation space occupied by the spiral retaining ring is smaller, and the appearance is more concise and beautiful. For occasions that do not require frequent disassembly, the advantages of the spiral retaining ring are more obvious.
