As a kind of fastener that is widely used in our daily industrial hardware, retaining ring is deeply loved by the public in the industry. It also has an alias called circlip. However, many people often think of circlips and retaining rings as the same thing. In fact, there are still many differences between the two. Let's introduce the difference between a circlip and a retaining ring.

Circlips, also called retaining rings or buckles, are a kind of hardware fasteners. There are many types of them. They are mainly installed in the shaft grooves or hole grooves of machines and equipment. Simply put, it plays a role in preventing the axial movement of the parts on the shaft or hole.

The circlip is an important part, which is a small equipment component, and the specifications are generally very small. The shape of the circlip is generally round, but there is a gap at one end. Put the circlip on the equipment that needs to be fixed, and then lock the gap with screws to keep the equipment stable. This is the function of the circlip. On CNC lathes, spindle circlips are commonly used as fixtures for clamping parts. Due to the better structure and accuracy of the spindle circlips, they are widely used in the manufacturing field. However, in the specific production process, the circlip lacks an axial positioning device and can only rely on the end face of the circlip and a specific tool for positioning. The specific operation is to move the tool to a fixed position set by the program, open the door of the machine tool to release the circlip, then pull the end face of the part to be processed until the tool surface fits, and then clamp the circlip of the spindle to close the machine door.

The current positioning method is complicated in operation and low in positioning accuracy, and cannot meet the accuracy of parts, the size of batches of parts vary greatly, and it cannot meet the rapid switching and processing of various types of parts in the production process.

Due to the addition of process holes, the circlip is easier to disassemble and assemble, but the protrusion at the installation process hole occupies a larger space, and there is a problem of occupying a large space whether it is for hole or shaft circlip.

Compared with the circlip, the elastic retaining ring has a multi-layer structure. The commonly used ones are 2 layers and 3 layers. There are no protrusions. The elastic retaining ring is very similar to the keychain. The difference is that the end of the retaining ring wire is reserved for The blessed corner cut will not interfere with other adjacent parts during assembly, so it is more convenient to use. Now for occasions that do not need to be disassembled frequently, the advantages of the elastic retaining ring are more obvious. In addition, the elastic retaining ring is formed by winding a flat wire, and after heat treatment and surface treatment, it has excellent elasticity and toughness.

In short: the cross-section of the elastic retaining ring is equal, the force is uniform, and the stress concentration phenomenon is reduced. The inner and outer edges are smooth and complete, there are no ear interference fittings, the inner and outer diameters are free of burrs, and it is convenient to disassemble and assemble. It can meet different needs by increasing or decreasing the number of layers. It does not need to make a mold. By changing the thickness of the material, it can be easily made for light load. Type, medium load type and heavy load type. The production cycle is short, and the materials available are wide. Spring steel, stainless steel, copper and other metal materials can be easily produced.
