A spiral retaining ring is a circular part fixed on the bearings, which can prevent other parts installed on the shaft from moving and axial tightness.
The spiral retaining ring is made of flat metal wire rolls. It is treated and treated with heat, and has good elasticity and toughness. The split shaft is used for axial positioning, double-circle, and multi-circle.
There are many materials for making elastic spiral retaining rings, such as spring steel, stainless steel, copper, and other metal materials. At present, the elastic spiral retaining ring materials commonly used in the market are 65mm, stainless steel 304, 316, 17-7PH, and 17-7PH. Some special elastic spiral retaining rings use copper alloy and high-temperature alloy materials.
From the perspective of appearance, there is a big difference:
Card springs usually have two craft holes for the blessing of calipers, and there are two obvious protrusions at the crafthole, while the spiral retaining ring does not protrude.
Double turn spiral retaining ring is very similar to the keychain. The difference is that the end of the wiring wire is used to bless the corner. As the crafthole is added, the script is more convenient for disassembly, but the space occupied by the protrusion at the installation process hole is large. Both the holes and the axis shaft have a large problem of occupying space.
Compared to the scripture, the spiral retaining ring has no process holes. It is not as convenient as the deck, but the installation space occupied by the spiral retaining ring is smaller, more concise, and beautiful. For occasions that do not require disassembly frequently, the advantages of the spiral block are more obvious.
So what is the difference between a deck and an elastic spiral retaining ring? Simply put, it plays a role in preventing axial movement on the shaft or in the hole.
Card springs are an important part. It belongs to a small equipment and components set, and the specifications are generally very small. The shape of the deck is generally round, but there is a gap at one end. Put the stuck spring on the equipment that needs to be fixed, and then lock the gap with the screw to keep the equipment stable. This is the role of the deck. On the CNC lathe, the main shaft deck is commonly used as a fixture holding part. Due to the good structure and accuracy of the spindle deck, it is widely used in the manufacturing field. However, in the specific production process, the device lacks an axial positioning device, which can only be located by the deck end surface and specific tools. The specific operation is to move the tool to a fixed position set by the program. Open the machine tool door to release the deck springs, then pull the end surface of the processing parts to the tool surface, and then clamp the main shaft card spring to close the machine tool door.
The current positioning method is complicated, and the positioning accuracy is low. It cannot meet the accuracy of the parts; the size of the batch parts is large; and it cannot meet the rapid switching and processing of a variety of parts in the production process.
As the crafthole is added, the script is more convenient for disassembly, but the space occupied by the protrusion at the installation process hole is large. Both the holes and the axis shaft have a large problem of occupying space.
Compared to the scallion, the elastic spiral retaining ring is a multi-layer structure. It is commonly used in 2 and 3 layers. There is no protrusion at all. It is used for blessing angles. It does not interfere with other adjacent components during assembly, so it is more convenient to use. Now that there is no need to disassemble frequently, the advantages of the elastic spiral retaining ring are more obvious. In addition, Lisheng Spring’s spiral retaining ring is formed by flat wires. After heat treatment and surface treatment, elasticity and toughness are excellent.
In short, the elastic spiral retaining ring section is equal, and the stress concentration is reduced. The inner and outer edges are smooth and complete, with no ear interference and matrix, inner and outer diameter-free edges, and easy to disassemble. You can meet different needs through the increase or decrease of the number of layers and do not need to make molds. By changing the thickness of the material, it can be convenient to make a light load, medium-load, or heavy load. The production cycle is short, and the optional materials are widely produced. Spring steel, stainless steel, copper, and other metal materials are convenient to produce.
