Several Main Factors Are Considered In Radial Clearance Of Double Row Deep Groove Ball Bearing

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.

Maintenance measures for simple faults of thin-walled deep groove ball bearing

The radial clearance of double row deep groove ball bearing refers to the amount of movement of one ring fixed and the other ring moving from one extreme position to another extreme position perpendicular to the axis of double row deep groove ball bearing. Whether the selection of bearing clearance is correct or not has a great influence on the accuracy of mechanical operation, bearing life, friction resistance, temperature rise, vibration and noise, etc. If the selection of centripetal bearing clearance is too small, the number of rolling bodies under load will increase, the contact stress will be reduced, and the operation will be more stable, but the friction resistance will increase, and the temperature rise will also be improved. On the contrary, the contact stress increases, the vibration is large, and the friction resistance decreases, and the temperature rise is low. Therefore, it is of great significance to choose the most appropriate clearance value according to the service conditions of bearings. When selecting the actual bearing clearance, the following main factors must be fully considered:

1. The tightness of double row deep groove ball bearing with shaft and housing hole will lead to the change of bearing clearance value. Generally, the clearance value will be reduced after the installation of bearings.

2. During the operation of double row deep groove ball bearing, due to the different heat dissipation conditions between the shaft and the housing, the temperature difference between the inner ring and the outer ring will be generated, which will lead to the narrowing of clearance value.

3. Due to the difference of expansion coefficient between shaft and shell material, the clearance value will shrink or increase.
