Cage of INA universal joint bearing service life

Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. According to the universal joint bearing installation, use, maintenance, maintenance of technical requirements, the operation of the INA bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. Installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. Bearing materials of metallurgical quality were the main factors influencing the premature failure of the universal joint bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still the INA bearing failure of one of the main influence factors. Select material adequacy is still bearing failure analysis factors must be considered. Bearing is zoning cage and keep two kinds of structure. One of the large bearing general requirements under high load, often without a cage, but full of rolling element between the inner and outer raceway. While most of the small and medium-sized rolling bearings are with cage. INA bearings in machining process, universal joint bearing outer ring, inner ring, rolling body and is how to a cage. Simply put, is to put the bearing inner and outer ring, inner ring pull over, and then put a rolling body ( On one side) , and then adjust the rolling body position, in the end, put the cage. Now we all know, in the process of bearing is a cage, so bearing cage main exactly is what effect? The role of the cage is: 1, lead and drive the roller in the correct roll on roll; 2, keep to separate rolling body equidistance, uniformly distributed in the race on the circumference of a circle in order to prevent the mutual collision and friction between the work roll body; 3, in the separated type bearings, the rolling body and a ring together, in order to prevent the rolling body fall off. Bearing called window, used to isolate and guide roller, the cage pocket hole clearance has certain activity in radial and axial, radial each. the called cage clearance. In roller cage has a variety of structural types, complicated shape. Keep on many equidistance hole, hole shape is spherical, tooth type, such as round, oval, rectangular, and its size is greater than the rolling body size, the difference between the two for the pocket hole clearance, sometimes part of the connection between the bearing cage window called the lintel, it ACTS as connection and increase strength of cage. INA bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished product universal joint bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. Analysis, the main task of the service life of INA bearings is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the universal joint bearing of sudden.
