What is deep groove ball bearing
Deep groove ball bearing, formerly known as single-row centripetal ball bearing, is the most widely used rolling bearing. It is characterized by small friction resistance, high speed, can be used to bear radial load or radial and axial combined load at the same time on the machinery, can also be used to bear axial load on the machinery, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machinery, tools and so on.
Characteristics of deep groove ball bearing
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing, and can bear radial and axial combined load. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specification and size as deep groove ball bearings, this kind of bearings has small friction coefficient and high limit speed. But not impact resistance, not suitable for heavy load.
Application of deep groove ball bearing
Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, engineering machinery, roller type roller skates, yo-yo, etc.
Method of preloading to improve the rigidity of deep groove ball bearing
1. Surface strain of single row deep groove ball bearing: cutting abrasive particles were found in the ferrogram, and the abrasive particles were composed of non-ferrous metals.
2.Single row deep groove ball bearing journal surface corrosion: spectral analysis found that the concentration of iron element is abnormal, there are many iron submicron particles in the iron spectrum, lubricating oil moisture or acid value exceed the standard.
3.Bearing tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements is abnormal; There are many submicron wear particles of non-ferrous metal composition in ferrogram. Lubricating oil moisture, acid value exceed the standard.
4. Bearing pad back fretting wear: spectral analysis found that the iron concentration is abnormal, there are many iron component submicron wear particles in the iron spectrum, lubricating oil moisture and acid value is abnormal.
Under the condition of liquid lubrication, the sliding surface is separated from the lubricating oil without direct contact, which can greatly reduce the friction loss and surface wear, and the oil film also has a certain vibration absorption ability
5.Single row deep groove ball bearing journal surface strain: there are iron cutting abrasions or black oxide particles in the iron spectrum, and tempering color exists on the metal surface.
