Influence Of Performance Of Thrust Self-aligning Roller Bearing Material On Service Life

What is Self-aligning roller bearings

The self-aligning roller bearing has a double row of rollers, and the outer ring has a common spherical raceway, and the inner ring has two raceways and is inclined to an Angle relative to the bearing axis. This ingenious structure enables it to have automatic self-aligning performance, so it is not susceptible to the influence of the Angle between the shaft and the bearing box seat on the error or shaft bending. It is suitable for the occasion of Angle error caused by the installation error or shaft deflection. The bearing can bear radial load as well as axial load for bidirectional use.

Characteristics of Self-aligning roller bearings

Mainly bear radial load, and can bear small axial load.The axial displacement of the shaft is limited within the clearance limit, and it has the performance of automatic self-altering. It can work normally under the condition that the relative inclination of the inner and outer parts is not large. It is suitable for the parts where the coaxiality of the supporting seat hole cannot be strictly guaranteed.

Application of Self-aligning roller bearings

Paper making machinery, reducer, railway vehicle axles, rolling mill gear box bearing block, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, vertical self-aligning bearing with belt seat.

Influence of performance of thrust self-aligning roller bearing material on service life

Use factor mainly refers to the installation and adjustment, use and maintenance, maintenance and repair, etc. Whether to meet the technical requirements. According to the technical requirements of the installation, use, maintenance and maintenance of universal joint bearings, the load, speed, working temperature, vibration, noise and lubrication conditions of the bearings in operation shall be monitored and checked, and the causes shall be immediately found out if any abnormality is found, and the adjustment shall be made to make them return to normal. In the case of further need of impact resistance, chromium steel, chromium molybdenum steel and nickel chromium molybdenum steel are used as thrust self-altering roller bearing materials, and carbonized quenching is adopted to make the steel have a hardened layer from the surface to the appropriate depth. Carburized bearings with appropriate hardening depth, fine structure, appropriate hardness of the surface and core hardness, than the use of bearing steel thrust self-aligning roller bearings have excellent impact resistance, the general chemical composition of the steel used in carburized bearings.

The stamping cage is made of low carbon steel. According to the use of different, also use brass plate, stainless steel plate. Cages are cut from high strength brass, carbon steel, and also synthetic materials.

The manufacture of thrust self-aligning roller bearings generally requires forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of bearings. The heat treatment and grinding processes which affect the quality of the finished universal joint bearing are often more directly related to the failure of the bearing. In recent years, the research on the modification layer on the working surface of thrust self-aligning roller bearing shows that the grinding process is closely related to the surface quality of the bearing.

The main task of service life analysis of thrust self-aligning roller bearings is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures to extend the service life of bearings and avoid sudden early failure of thrust self-aligning roller bearings.
