A bearing ring is an annular part of a radial rolling bearing with one or more raceways. The bearing ring is divided into an inner ring and an outer ring, wherein the bearing outer ring is the bearing ring on the inner surface of the raceway. Today, Langche Bearing will talk about the bearing outer ring.
Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling body and cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role.
1. NitroMax steel (high nitrogen stainless steel); 2. Standard bearing steel; 3. Ceramic.
The performance required by the bearing ring material: high rolling fatigue strength, high hardness and high wear resistance.
Due to the performance requirements of rolling bearing rings, all countries have formulated special bearing steel materials. Most of the bearings use high carbon complex bearing steel. .
1. Forging: Over-burning, overheating, and internal cracking into reticulated carbides will reduce the toughness and strength of the ferrule during the forging process. Therefore, it is necessary to strictly control the processing temperature, cyclic heating and post-forging heat dissipation conditions (such as spray cooling), etc., especially after the final forging of larger varieties of ferrules, the temperature is above 700 ℃, and they should not be stacked and placed.
2. Heat treatment: Close monitoring of heat treatment equipment is an important work in the workshop. Monitoring equipment reliability. Important temperature control equipment such as instruments and thermocouples must be closely monitored to ensure accurate and reliable measurement data; those with errors exceeding the standard should be replaced in time, and it is strictly forbidden to operate with illness.
3. Monitoring of grinding process. The finished imported bearing ring is not allowed to have grinding burns and grinding cracks, especially the matching surface of the inner ring screwdriver must not have burns. If the ferrule is pickled, it should be fully inspected, and the burnt products should be excluded. Those with severe burns that cannot be repaired or those that fail to be repaired should be scrapped. The ferrules with grinding burns are not allowed to enter the assembly process.
4. Identification management. After the steel is stored in the warehouse and before the ferrule grinding, each process must be strictly managed, and the two different materials and products of GCR15 and GCR15SIMN are strictly distinguished.
