Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball bearings, in particular to an impact-resistant deep groove ball bearing structure. Background Art

[0002] Deep groove ball bearings are suitable for high or even extremely high speed operation, and are very durable and do not require frequent maintenance. This type of bearing has a small friction coefficient, a high limit speed, and a variety of size ranges and forms. It is used in precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most widely used type of bearing in the machinery industry. It mainly bears radial loads and can also bear a certain amount of axial loads.

[0003] During the use of deep groove ball bearings, the deep groove ball bearings may be disturbed by the external environment or impacted, resulting in errors in the inner and outer rings of the deep groove ball bearings, and the rotation of the balls inside the inner and outer rings is hindered. Although existing deep groove ball bearings are provided with dust covers at the intersection of the inner and outer rings, the dust covers are interference-connected during installation. When impacted, the dust covers and the connection become loose, resulting in a decrease in the protection effect. Utility Model Content

The protective cover 3 can protect the fixing frame 4 at the intersection of the outer ring 1 and the inner ring 2, and a buckle 7 is provided at the intersection of the outer surface of the inner ring 2 and the protective cover 3. When the protective cover 3 is installed, the protective cover 3 is clamped with the buckle 7, so that the protective cover 3 is tightly clamped with the inner ring 2 and the outer ring 1 at the intersection. When the deep groove ball bearing is impacted, the protective cover 3 protects the internal fixing frame 4, and through the clamping of the buckle 7, when the protective cover 3 is slightly deformed, it will not fall off at the connection with the inner ring 2.

[0027] A groove 6 is provided at the position of the ball 5 in the outer ring 1, a slot is provided on the outer surface wall of the inner ring 2, and the rolling assembly is recessed in the groove 6. The rolling assembly includes a fixing frame 4 and a ball 5 arranged inside the fixing frame 4. The fixing frame 4 has two pieces in total, and connecting screws are screwed inside the two fixing frames 4. The ball 5 is placed inside the two fixing frames 4, and then the connecting screws are taken out. The two fixing frames 4 are connected by the connecting screws, so that the balls 5 inside the two fixing frames 4 can be tightly connected, and the ball 5 and the fixing frame 4 are in rolling connection.
