The Bearing Is A Mechanical Component Aug 23, 2017


The bearing is a component that fixes and reduces the load friction coefficient during mechanical transmission. It can also be said that when other parts in the shaft relative to each other when the relative movement, used to reduce the power transmission process of friction coefficient and maintain the axis of the central position of the fixed parts. Bearing is a contemporary mechanical equipment in a pivotal component. Bearings Its main function is to support the mechanical rotating body, to reduce the equipment in the transmission process of the mechanical load friction coefficient

Bearings can be divided into a variety of, rolling bearings, radial bearings, ball bearings, thrust bearings and so on.

The role of it should be support, that is, literal interpretation of the shaft, Bearings but this is only part of its role, to support its essence is able to bear the radial load. It can also be understood that it is used to fix the shaft. It is fixed shaft so that it can only achieve rotation, and control its axial and radial movement.

The motor does not have the consequences of bearing is simply can not work. Because the shaft may move in any direction, Bearings and the motor requires that the shaft only be rotated when working.

Theoretically speaking, it is impossible to achieve the role of transmission, not only that, the bearing will affect the drive, in order to reduce the impact of high-speed shaft bearings must achieve good lubrication, Bearings and some bearings themselves have lubrication, called pre-lubricated bearings, and Most of the bearings must have lubricants, responsible for high-speed operation, because the friction will not only increase energy consumption, Bearings more terrible is easy to damage the bearings.

Although many types of bearings and varieties, and have their own inherent characteristics, but compared with the sliding bearing, but has the following common advantages:

1) bearing friction coefficient is small, so the friction resistance and start friction torque is small, Bearings less power consumption;

2) Dimensions have been international standardization, serialization, generalization, Bearings suitable for mass production, interchangeability, easy to install, disassemble and repair;

3) bearing internal clearance is very small, high precision, can be applied by preload to improve bearing rigidity, which is very important for precision machinery;

4) bearing drive high efficiency, less heat, easy lubrication and maintenance, saving lubricant;

5) load, speed and operating temperature range of a wide range of working conditions, Bearings a small amount of changes in the performance of the bearing has little effect;

6) In general, most types of bearings can simultaneously bear radial and axial loads, can simplify the structure.
