The main materials of our company's flattened wire retaining rings are 65Mn, SWRH72B, SWRH82A, 60Si2Mn, etc. We can choose wires of different materials for processing according to the use environment of the retaining rings, and we can also design different materials according to the requirements of the provided drawings.

The forming process of the flattened wire retaining ring mostly adopts sheet punching or wire winding. Among them, the functional cross-section of the retaining ring made by the sheet punching process is conical, and it is mostly "linear contact" after assembly; while the wire winding forming process is made by punching excess materials, and its cross-section is a regular rectangle, and it is "surface contact" after assembly.

Our company uses the wire winding forming process to process this type of flattened wire retaining ring to increase the contact surface between the retaining ring and the groove to form "surface contact", so that it has a greater radial clamping force to meet the requirement that the transmission shaft will not fall out when it rotates.

Our company's manufacturing process is: winding → heat treatment → forming → vibration grinding → surface treatment → packaging. According to the different sizes and grouping requirements of the thickness of the parts, grinding, laser engraving and other processes will be added; according to the different use environments of the parts, the surface treatment can be divided into anti-rust oiling, oxidation blackening, phosphating, ultrasonic cleaning and other processes, among which ultrasonic cleaning can meet the use environment of DCT, AT and new energy box types with higher cleanliness requirements.

Due to the superiority of the wire winding molding process, relatively good quality and performance can be achieved. At present, some of our company's parts of this type can reach a maximum speed of 20,000r/min without falling out, meeting the high speed requirements of new energy high-speed motors, AT, and DCT gearboxes.

The specifications and sizes of flattened wire retaining rings are varied to meet the needs of different mechanical devices. Common specifications and sizes include nominal diameter, height, thickness, etc., and specific sizes can be customized according to actual needs.

For customers who are not familiar with the matching dimensions, you can also choose according to the automotive industry standards of QC/T 344 "Flattened wire retaining rings for holes", QC/T345 "Flattened wire retaining rings for shafts", or GB/T 305 "Rolling bearings, radial bearing retaining grooves and retaining rings, dimensions, product geometric technical specifications (GPS) and tolerance values".

For use environments with strict matching dimension requirements, parts can be processed into different thickness groups by grinding, and the parts can be used to adjust the shaft tooth clearance. At present, the minimum thickness requirements that our company can meet are t±0.015mm (diameter Φ25~100mm, thickness above 1.5mm), t±0.025mm (diameter Φ20~200mm), and t±0.05mm (diameter Φ20~400mm).

Flattened wire retaining rings are widely used in various mechanical devices, such as automobiles, aerospace, ships, machine tools, etc. They play an important axial limiting role in these fields, ensuring the normal operation and safety of mechanical devices.
