Analysis: Key technical processes for bearing surface treatment

    1. The main raw materials: ultra-high molecular polyester borane polymer resin; nano-molybdenum disulfide; anti-rust and oil-absorbing nano-group; trace polytetrafluoroethylene and other mixture of nano-powder. All the above raw materials are independently developed by our company and can be produced in small quantities in the laboratory.
    2. Uses: Improve the surface anti-rust ability of the bearing; reduce the surface friction coefficient; comprehensive performance of friction and wear resistance.
    3. Suggestions for use:
    1) Remove the oil from the bearing surface such as rust. 1. Mix with 1% to 3% of the industrial high-efficiency degreasing powder we developed, and put the bearing ring into the liquid to warm it to 70 degrees to 85 degrees. 30 minutes (intermittent stirring), stop heating and wait until the temperature is 40 degrees or so. Dip the bearing ring in water one by one and brush with the brush. In particular, the bearing work surface should be brushed several times. When brushing, the bearing ring can't leave the water surface. Note : This liquid can remove the oil beads floating on the water surface and reuse it once; 2. Rinse twice with water of about 40 degrees, the two rinse waters can be reused; when the oil is heavy, use 3% ratio and re-mixing Wash the liquid twice;
    2) Use LM-1198A super concentrated cleaning solution to remove the lubricating oil immersed in the micropores of the bearing phosphating layer, and let the resin be replaced by molybdenum disulfide. The specific method is 0.5%. Proportion and water with cleaning agent to warm to 85 degrees to 99 degrees (drip down the cleaning agent can be connected to cool, remove the floating oil on the surface after the oil beads can be reused once), soak the bearing workpiece in the cleaning agent with a brush, once Rinse twice with water at a temperature above 70 degrees.

Analyze the cause of defects in bearing surface grinding

During the grinding process, the working surface of the bearing is ground by a grinding wheel that rotates at a high speed. Therefore, if the equipment is not operated and adjusted according to the operation instructions during grinding, various defects will occur on the working surface of the bearing, thus affecting The overall quality of the bearing. When the bearing is in precision grinding, the roughening requirements are very high, and the grinding marks appearing on the working surface can be observed by the naked eye.

     Performance showing cross spiral traces

     The reason for this kind of trace is mainly due to the poor straightness of the busbar of the grinding wheel and the unevenness. When grinding, the grinding wheel and the workpiece are only partially in contact. When the workpiece or the grinding wheel reciprocates several times, the performance of the workpiece will reappear. The spiral is visible to the naked eye. The pitch of these spirals is related to the workpiece table speed and the workpiece rotation speed, and is also related to the grinding wheel axis and the table rail.

Key points for applying force when assembling and dismounting bearings

Core Tips: (1) The force of the force applied is as far as possible through the axis of the bearing, which requires that the point of application of force is evenly symmetrical and stable, and the force is applied through the spherical surface or parallel to the axis. (2) The size of the force should be smooth and uniform.
(1) The force of the applied force passes through the axis of the bearing as much as possible, which requires that the point of application of the force is uniformly symmetrical and stable, and the force is applied through the spherical surface or parallel to the axis.
(2) The size of the force should be smooth and uniform, and it is not suitable for impact. This requires the use of oil pressure or a tool that can apply a smooth pulling force or pressure. When it is necessary to use hammering, it must also be soft through a copper sleeve. It is buffered without falling metal, and the tapping force is as gentle as possible. It is best to use a copper rod or a copper hammer for hammering.
(3) Avoid applying force through the rolling element. This requires the force applied through the inner ring when the inner ring (shaft ring) is removed or removed, and the force is applied through the outer ring when the outer ring is assembled or removed.
(4) The drag force should be continued to the extent that it should be, for example, when installing the bearing, stop the force when the bearing is just in the correct position, and ensure that the end face of the ferrule (gasket) abuts against the seat hole or the shoulder end face of the shaft. Can not be squeezed too tightly, and can not be installed.

Possible causes of early damage to the bearing

Core Tips: 1. Improper installation (about 16%) 1. Use brute force during installation. Directly hitting the bearing with a hammer will cause the greatest damage to the bearing; it is the main cause of deformation. 2, Ann
First, improper installation (about 16%)
1. Use brute force during installation. Directly tapping the bearing with a hammer will cause the greatest damage to the bearing; it is the main cause of deformation.
2, the installation is not in place, the installation is biased or not installed to the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, causing disagreement.
    Recommendation: Select an appropriate or professional bearing installation tool, and use a special instrument to detect it after installation.
    Second, poor lubrication (about 50%)
    According to the survey, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: not adding lubricant or lubricating oil in time; lubricant or lubricating oil is not filled in place; improper selection of lubricant or lubricating oil; incorrect lubrication method, etc.
Recommendation: Choose the right lubricant or lubricant and use the correct lubrication method.
    Third, pollution (about 14%)
Contamination can also lead to premature bearing damage, which means that dust, metal chips, etc. enter the bearing. The main reasons include: opening the bearing packaging too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is not clean, and the working medium is polluted.
Recommendation: It is best not to disassemble the bearing before use; keep the installation environment clean during installation, clean the bearing to be used; and strengthen the bearing seal.
    Fourth, fatigue (about 34%)
Fatigue damage is a common way of damage to bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; improper maintenance; equipment aging.
Recommendation: Select the appropriate bearing type and replace the fatigue bearing regularly.
