What is the manufacturing method of the circlip?
The manufacturing method of the circlip: In the mechanical design, the spring often bears the alternating load with impact, so the spring material should have high yield strength, fatigue strength, impact toughness and good heat treatment performance. Commonly used spring materials are high-quality carbon steel, alloy steel, and non-ferrous metal alloys.
The main functions of springs include: controlling movement or limiting positions, such as springs in cam mechanisms, clutches, valves, etc.; buffering and absorbing vibrations, such as vehicle springs, springs in spring-yellow couplings, etc.; storing energy, such as clocks and instruments Springs; measuring force and torque, such as springs in spring scales and dynamometers;
Circlip
The manufacturing process of the circlip mainly includes winding, hook making or both end surface processing, heat treatment and process performance test, and necessary strengthening treatments such as strong pressure or shot peening. There are two winding methods: cold rolling and hot rolling. Spring steel wire with a diameter of less than 8-10mm uses cold coils when manufacturing springs. Cold-coiled springs are mostly cold-drawn, high-quality carbon spring steel wires that have been heat-treated in advance. After coiling, they are only tempered at low temperature to eliminate internal stress. Hot coils are used for springs with larger diameter spring steel wires. According to the different diameters of the spring wires, the hot coil temperature is selected in the range of 800-1000℃, and quenching and tempering are required after coiling.
For important compression springs, in order to ensure that the bearing surfaces at both ends are perpendicular to the axis, the end rings should be ground on a special grinder to reduce the possibility of skew under load; for tension and torsion springs, in order to facilitate connection and Load, hooks should be made at both ends. In order to improve the load-bearing capacity of the spring, strong pressure, strong tension or shot peening can be carried out. The compression treatment of the compression spring is that after the spring is rolled, the spring is compressed until the turns of the spring are in contact with a load exceeding the elastic limit of the spring material, while maintaining 6-48h, so as to produce plastic deformation in the spring wire, and produce in the spring after unloading The residual stress. Because the direction of the residual stress is opposite to the working stress, the maximum stress of the spring during operation is smaller than that of the spring without strong pressure treatment, so the load-bearing capacity of the spring can be improved. The tension spring is subjected to strong tension processing. After the spring is subjected to strong pressure and strong tension, no heat treatment is allowed, and it is not suitable to work under high temperature 150-450℃ and long-term vibration, otherwise it will lose the above effect.
What material is the circlip made of?
The material is 65Mn (spring steel), the heat treatment hardness is HRC44～51HRC, and the surface is oxidized.
How to remove the retaining ring?
First remove the single-sided bearing. Although the outer ring of the bearing is the inner hole of the gear, the inner ring of the bearing and the cylindrical roller can be removed. Only after the single-sided bearing is removed can the retaining ring for the hole be removed with a circlip
