The main factors used for adjustment are installation, use and maintenance, maintenance, etc., which meet the technical requirements. According to the technical requirements for the installation, use, maintenance and maintenance of double row deep groove ball bearings, the operating Koyo bearings are monitored and inspected for contact load, Groove Ball Bearing speed, temperature, vibration, noise and lubrication status.
In case of abnormalities, immediately find out the causes and adjust them to make them return to normal. Groove Ball Bearing The installation condition is one of the factors for using the bearing. It is the primary factor of the load-bearing force that often causes the state change between various parts of the incorrect installation package, and the early termination of abnormal operation state and life. Internal factors mainly refer to structural design, manufacturing process and materials.
The situation I saw at the scene was amazing. It was good to use the double row deep groove ball bearing of needle roller series at this level. Because of this wear, the common relationship between bearing and shell, Koyo bearing and shaft was destroyed, resulting in the axis deviation from the accurate position and abnormal noise when the shaft was moving at high speed. When the bearing is tired, the metal on its surface will peel off, which will also increase the radial clearance of the bearing and make abnormal noise.
When disassembling the lower Koyo bearing for maintenance, first record the appearance of the needle roller bearing, confirm the residual Groove Ball Bearing amount of the smoothing agent, and wash the bearing after sampling the smoothing agent for reflection. As a cleaning agent, gasoline and petroleum are widely used. In order to judge whether the disassembled bearing can be used, it is necessary to reflect after the bearing is cleaned.
I don’t think these above are the primary reasons for the problems of double row deep groove ball bearings. I think this customer’s daily use Groove Ball Bearing of bearings is not well protected, so it leads to such a situation.
The rationality, advanced nature and stability of the treatment will also affect the service life of the bearing. Affecting the heat treatment and grinding process of Koyo bearing is often more directly related to the fault of bearing and related product quality. In recent years, the research on the deterioration of bearing surface layer shows that the grinding process is closely related to the bearing surface quality.
Centripetal thrust ball bearing is a precision part, so Groove Ball Bearing 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, and it is easy to damage the bearing. Therefore, pay attention to the following matters when using bearings:
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.
