Timken bearing is a precision part of mechanical equipment. The system realizes the optimization of workshop asset efficiency and maintenance work for the decision Timken Bearing During Use support of mechanical service, preventive maintenance means, condition monitoring and a series of maintenance work.
Therefore, Timken bearing plays a vital role in some industries. When the deep groove ball bearing has the following conditions, please do not continue to use it, Timken Bearing During Use and replace it with a new bearing immediately. Avoid unnecessary accidents:
(1) There are cracks or notches on any one of the inner ring, outer ring, rolling element and cage of Timken bearing; (2) Timken Bearing During Use The inner ring inner diameter surface or outer ring outer diameter surface of deep groove ball bearing has obvious creep; (3) The raceway surface, retaining edge and rolling element of the bearing are significantly jammed; (4) Obvious discoloration caused by heat;
(5) There is rust and damage on the raceway surface and rolling element of the bearing; (6) There are serious indentations and scratches on the raceway surface and rolling element of the bearing; (7) Timken Bearing During Use Any one of the bearing rings and rolling elements is broken; (8) The cage of the bearing is significantly worn or the rivet is significantly loose.
the force application point shall be uniform, symmetrical and stable. Timken Bearing During Use The force shall be applied through the spherical surface or parallel to the axis, and the resultant force shall pass through the axis of Timken bearing as far as possible.
Second, use oil pressure or tools that can apply stable tension or pressure. The force should be stable and uniform without impact. If necessary, hammer can be used. When hammer is used, Timken Bearing During Use it should be buffered by soft metal such as copper sleeve without chip falling, and the knocking force should be as light as possible. Hammer with a copper rod or hammer.
Third, when installing and removing the inner ring (shaft ring), apply force through the inner ring, and when installing and removing the outer ring, apply force through the outer ring to avoid applying Timken Bearing During Use force through the rolling element.
Fourth, when installing Timken bearing, stop applying force when the bearing is just installed in the correct position, and ensure that the end face of the ferrule (washer) is against the seat hole or the shoulder end face of the shaft. Timken Bearing During Use It can not be squeezed too tightly or installed in place, and the drag force should continue to the due degree.
so it is required to be quite cautious in use, that is, it uses high-performance bearing. If it is not used properly, it can not achieve the expected performance effect, Timken Bearing During Use and it is easy to damage the bearing. Therefore, pay attention to the following matters when using bearings:
However, under some special operating conditions, the centripetal thrust ball bearing can obtain a longer life than the traditional calculation, Timken Bearing During Use especially under light load. These special operating conditions are the surface damage that may be caused when the rolling surface (track and rolling parts) is effectively separated and limited by a lubricating oil film. In fact, under ideal conditions, the so-called permanent bearing life is possible.
Grease lubrication includes the sealing method of filling grease in the sealed bearing in advance, and the filling grease supply method of filling an appropriate amount of grease in the shell and replenishing or replacing it at regular intervals. In addition, the centralized grease supply mode with pipes connected to each lubrication point is also adopted for the machinery with multiple centripetal thrust ball bearings that need lubrication.
Grease lubrication can be filled with grease for a long time without supplement, and the structure of its sealing device is simple, so it is widely used. Oil lubrication is relatively simple. The installation and disassembly method of centripetal thrust ball bearing shall be determined according to the structure, size and matching nature with bearing components.
The pressure of installation and disassembly shall be directly added to the end face of the tight fitting retaining ring, and the pressure cannot be transmitted through the rolling element, because it will cause indentation on the working surface of the bearing, affect the normal operation of the bearing, and even damage the bearing. The cage, sealing ring, dust cover and other parts of the bearing are easy to deform, and the pressure for installing or removing the bearing cannot be added to these parts.
