Mechanical maintenance of bearing maintenance

1. Bearing maintenance.
Mechanical equipment, bearing failure occurs, in the bearing is removed for maintenance, to record the appearance of the bearing, check the bearing lubricant inside the residual stock, to save lubricant sampling, kerosene or gas bearing for easy cleaning.Clean the bearing of removed, advanced coarse fine clean after cleaning.Place the bearing placed on the container, do the bottom metal mesh, avoid bearing directly remove the dirt at the bottom of the container.
For coarse when cleaning, avoid bearing rotating along with dirt, avoid the damage of bearing rolling surface.
Use the brush to remove adhesive content and grease, into the fine cleaning steps.Bearing in place to clean oil, while rotating cleaning, clean the dirt on the oil, to change in time, ensure the fine cleaning effect.Can continue to use to judge the bearing of the disassembly, need in the bearings cleaning after the completion of the inspection.
Foreign body of bearing inspection projects including: bearing, bearing clearance, bearing abrasion of dimensional accuracy, bearing frame, cooperate with the state, rolling surface, raceway surface state, the running state of the ball or roller, etc.
For non separation of small ball bearing to the bearing inner ring with one hand flat, identified by rotating outer bearing can smooth operation.On the external ring of conical roller bearings to raceway surface and rolling body check.

2. The bearing maintenance and matters needing attention.
(1) bearing installation.
In the process of mechanical maintenance, bearing maintenance to install has higher requirements.Due to the bearing in appearance does not have evident in the external features, either forward or reverse can be installed, the phenomenon of extremely easy to appear.In the process of bearing assembly, maintenance personnel of the bearing structure and installation requirements have fully understand, be familiar with the safety technology main points, according to the design requirements, installed correctly.
Conical bearing including "back-to-back" and "face to face" installation method, if the installation error will cause the axial channeling dynamic and cannot be adjusted;If the structure of bearing and install a lack of understanding, in the face of the plane bearing ring and loose circle, easily installed backwards, leading to dysfunctional after assembly, the mechanical equipment to produce much more failure.
(2) bearing its own defects.
Mechanical maintenance process, to the bearing code and model of equipment to fully understand the technical indicators, such as information, try to rotate the original model to avoid using the substitution model.
In practice, some equipment often replace the bearing, and bearing after the replacement is very likely to burn out, this is usually due to bearing model is different, use alternative bearing, bearing own existence that are a direct result of quality defects.
Due to sell on the market of bearing quality and time not neat, there is the phenomenon of shoddy, long-term use of inferior bearing parts, to do long-term mechanical equipment wear and tear, reduces the service life of the equipment.
Rotate bearing to avoid mechanical maintenance, long-term inventory of accessories, for the bearing appearance inspection, testing functions, to ensure the quality of the bearing.
Bearings are important for mechanical operation, by keeping lubrication, avoid foreign bodies in, avoid overload overspeed, can prolong service life.For bearing maintenance, to analyse the reason of breakage, take targeted measures, to ensure the quality of maintenance, improve equipment operation efficiency.
