Processing Process Steps Of 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.

Processing process steps of deep groove ball bearing

1. Processing of tube billet: the bearing steel is heated to 1150℃ ~ 1200℃ in a heating furnace, and the heated tube billet is perforated with a perforating machine to produce capillary tubes.

2.Spheroidizing annealing: the capillary spheroidizing annealing, annealing after the hardness range of the capillary HRB88 ~ 94.

3. Hot rolling of tube billet: send the annealed tube into the heating furnace for secondary soaking; After the second soaking, the capillary tube is rolled to form a waste pipe by reducing diameter, reducing wall and extending.

4. Pipe blank shaping and cutting: the pipe passes through the sizing unit for sizing and shaping, and then straightening and cutting to form the kit.

5.Recrystallization annealing: the kit for recrystallization annealing treatment, eliminate work hardening, so as to facilitate the implementation of cold rolling.

6. Soft grinding kit: Soft grinding suite of double end face, and then soft grinding cylindrical suite, first double end face grinding, cylindrical grinding, cylindrical is through grinding, between material and material through the transverse joint together to carry on the processing, ensure parts outside diameter surface and plate in the same plane, ensure outer diameter taper under control, adjustment of double end face grinding of the Angle between the grinding wheel, control end face parallel to the poor, The precision of the end surface is used as the datum of the subsequent processing. The outer circle is processed by centerless grinding.

7. Kit hole: drill the stop plug hole and oil hole on the surface of the kit, and rough the surface of the inner hole of the kit to prepare for the surface of the inner hole of the cold rolling.

8. Cold rolling kit: for cold rolling of deep groove ball bearing ring raceway, there are 6 stages of core roll feed speed in the cold rolling process, the speed range is 0.4mm/s ~ 1.0mm/s, and the speed curve is fast, slow, slow, until stop within a processing cycle. The rolling time is between 6s and 14s, and the rolling pressure is 80kN.

9.Turning kit: the kit for car chamfering, sealing groove.

10.Fine grinding kit: fine grinding kit, improve the surface accuracy of the kit.

11.Bearing installation: put the ball between the rings, install the cage, inject grease, install the seals, and complete the assembly of the deep groove ball bearing.
