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 for solving heating problem of double row deep groove ball bearing
Under normal circumstances, the temperature of double row deep groove ball bearing should be about 30 ° C, and the highest temperature should not exceed 70 ° C. Otherwise, it will be deformed because of the high temperature of the bearing. In serious cases, it will directly damage the jaw crusher, and even lead to the machine explosion. Therefore, it is more urgent to keep an eye on the bearing temperature of the jaw crusher, especially the coming of summer.
First, bearing wear or cage damage. Second, axial channeling of the tight set bushing occurs. Third, the bearing is broken or the oil is injected too much. Four. The position of the crusher flying groove wheel counterweight block is off track and the frame is jumping. Five, the oil hole is blocked, the oil cannot be added. 6. The bearing is not heated up, but the movable jaw sealing sleeve and the end cover are heated by friction or the double cover of the bearing seat of the frame is rotated with the spindle to generate friction and heat.
1. Keep the bearing clean and lubricated
Before checking the double row deep groove ball bearing, the surface of the bearing should be cleaned first, and then carefully check the oil seal of the bearing and its surrounding parts. If it has shown bad symptoms, be sure to replace it. The bad oil seal will cause damage and make the bearing cloud abnormal and cause the shutdown of the equipment.
2. Pay attention to cover exposed bearings
Do not expose double row deep groove ball bearings to contaminants or moisture when checking bearings. If the work is interrupted, the machine should be covered with oil-paper plastic film or similar materials. If the unmasked bearing is cleaned without disassembly and inspection may be performed, it shall be cleaned with a coating brush stained with petroleum solvent, and then dried with a non-pilling cloth or blown dry with compressed air (be careful not to allow the bearing assembly to start rotation).
