Use factors mainly refer to whether the installation, Life Of Koyo Bearing adjustment, use and maintenance, maintenance and repair meet the technical requirements. According to the technical requirements of Koyo bearing installation, use, maintenance and repair, monitor and inspect the load, speed, working temperature,
vibration, noise and lubrication conditions of the running bearing, find out the causes immediately and adjust them to make them return to normal. The installation condition is one of the primary factors in the use factors. The improper installation of the bearing often leads to the change of the stress state between the parts of the whole bearing.
The bearing operates in an Life Of Koyo Bearing abnormal state and ends its service life early. The internal factors mainly refer to the three factors that determine the bearing quality, such as structural design, manufacturing process and material quality.
The metallurgical quality of imported bearing materials was once the main factor affecting the early failure of rolling bearings. Life Of Koyo Bearing With the progress of Metallurgical Technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved.
The proportion of raw material quality factor in bearing failure analysis has decreased Life Of Koyo Bearing significantly, but it is still one of the main influencing factors of bearing failure. Proper material selection is still a factor that must be considered in bearing failure analysis.
The manufacturing of bearings generally goes through multiple processing processes such as forging, heat treatment, turning, grinding and assembly. The Life Of Koyo Bearing rationality, advanced nature and stability of all the processing technologies will also affect the life of bearings.
Among them, the heat treatment and grinding processes that affect the quality of finished bearings are often more directly related to the failure of bearings. In recent years, the research on the metamorphic layer on the working surface of bearing shows that the grinding process is closely related to the surface quality of bearing.
The main task of Koyo bearing service life analysis is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures, prolong the service life of the bearing and avoid sudden early failure of the bearing.
It is on the holder and in the cavity of the bearing cover, and forms a contour on the periphery of the Life Of Koyo Bearing rolling element. During this process, the bearing temperature rises rapidly due to the resistance of excess grease.
Although most of the excess grease is squeezed out at the initial stage of operation, and the grease squeezed in the accessories of the raceway may still be brought into the raceway by the rotating rolling element.
In the initial stage of bearing operation, most of the grease is quickly squeezed out of the Life Of Koyo Bearing raceway (less than one minute), and the accumulated grease is discharged in a small amount while circulating with the rotating body of the bearing.
At this time, the bearing Wendu continues to rise until all the excess bearing grease is discharged, which can be called the running in stage of grease. According to the quality and filling amount of grease in the bearing structure, this period may last for more than ten minutes or even several hours.
After the remaining Koyo bearing grease is completely discharged, the remaining small amount of grease forms a thin layer of grease film on the mutual contact surface of the rolling element, raceway and cage through the action of a wedge, so as to enter the normal operation stage of the bearing.
At this time, the temperature gradually decreases and reaches equilibrium. In other words, the Life Of Koyo Bearing long-term lubrication mainly depends on this layer of grease film. In addition,
it also plays a role in the long-term operation of the lubricating oil inlet and outlet part of the rolling frame, and it also plays a role in the long-term operation of the lubricating Life Of Koyo Bearing oil inlet and outlet part of the rolling frame.
Different bearing greases form different contours in the bearing. The contour must be formed. It is quite draft, the running in time is short, and the bearing temperature is low and stable in long-term operation. This is an ideal grease, so it is particularly important for the channelization of the grease.
Some so-called vortex type greases are not the case. They are not easy to form a contour. Even if the contour is formed, they are easy to collapse.
At this time, the excess grease returning to the raceway repeatedly is in the condition of forced stirring for a long time. The torque of Koyo bearing is large, the temperature is high, and it is unbalanced. It may also produce noise, and the grease is easy to deteriorate and lose.
