The installation of deep groove ball bearing load charge maintenance method

When the TIMKEN bearing rotation, TIMKEN bearing inner ring and outer ring raceway surface with rolling body is rolling contact, as the dark side, thus orbit trajectory are attached to the raceway surface does not belong to abnormal, the change can be learned that load conditions, so when remove the TIMKEN bearings, please keep close attention and observation on the surface of the raceway. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Can check if the bearing with accidents such as whether the load and the installation error of kingdoms, the cause of bearing damage and be investigated for clues. Correct installation of deep groove ball bearing is the assurance of its service life extension, many people do not have the professional knowledge at the time of installation is not particularly in place, easy to cause the bearing to improper installation, prone to mechanical operation accidents, as a professional mechanical maintenance engineers must know something of the bearing installation. In general bearing installation is in accordance with, deep groove ball bearing structure, size, and part of the installation, and to determine the nature of the cloud, at the time of installation note when pressure is directly in the ring on the surface, must be vertical pressure, not by turning to pressure roller bearings installed more general method is as follows: with shaft bearing ring with way more for transition fit, the bearing seat with bearing hole with more is clearance fit, such cooperation way in general are relatively easy to install, in the center axis of the bearing should be on the shaft fixed well, lest the circumferential relative weeks turn, lead to unnecessary wear and tear. Here bearing installation, rotating more some installation way, so that we can make inner ring can be more tight some axis. Bearing outer ring and bearing seat with relatively loose, the inner ring with shaft with relatively tight time, can use the installation of deep groove ball bearings use professional press to the bearing pressure on the shaft, then install with shaft, bearing to the bearing seat, at the time of pressure installation note on crossroads to the face of the bearing inner ring, then pad made of a soft metal casing, the material is copper or mild steel is ok, the assembling casing diameter is greater than the diameter of a journal, outside diameter is larger than that of inner ring gear side was a little child, avoid pressure in the rack. About the test results that can be used by bearing the judgement or master of bearing. Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, deep groove ball bearings shall not be used again, must be replaced. 1) Bearing parts of rupture and defects. 2) The raceway surface material on the surface of the rolling strip. Bearing fault identification method to remove the check, can identify or predict the bearing has a trouble-free operation, to increase productivity and efficiency is very important. Main recognition method is as follows: 1) Through the voice recognition through the voice recognition need to have a lot of experience. Must pass a fully trained to recognize voice bearing and deep groove ball bearings. Therefore, should as far as possible from staff to carry out the work. With listening gear or listening bar on the shell can be clearly heard the sound of the bearing. 2) Through the method which can identify working temperature comparison method of identification, is limited to use in place of running condition is not change. Therefore, must carry out continuous recording of temperature. Failure, temperature not only, also can appear irregular change. 3) Through the state of lubricant, and the recognition of lubricant sampling analysis, through its pollution degree is mixed with foreign bodies in the judgement or metal powder, etc. The method is to can't close to the observation of the deep groove ball bearings or large bearings are particularly effective.
