Problems solved by technology
Due to its structural characteristics, deep groove ball bearings can withstand a certain radial load. However, once the radial load is too large, it will intensify the degree of wear between the rolling elements and the outer ring and inner ring, resulting in deformation of the rolling elements and eventually lead to The structure in which the rolling elements are stuck and the bearing is scrapped will cause damage to the equipment

Embodiment
[0025] A kind of anti-deformation deep groove ball bearing, refer to Figure 1-Figure 4 As shown, it includes outer ring 1, inner ring 2, cage 3 located between outer ring 1 and inner ring 2, and rolling elements 4 distributed on the cage 3 at intervals in the circumferential direction. The outer ring wall of the ring 2 is respectively provided with a main raceway that cooperates with the rolling body 4, and a dust cover 6 is fixed on both sides of the inner ring 2 to block the gap between the inner ring 2 and the outer ring 1, and the dust cover 6 is connected to the inner ring. The ring 2 is plugged and matched, and the position is limited by the limit mechanism. After the dust cover 6 is plugged with the outer ring 1, the gap fits to prevent dust.
[0026] For details on the cooperation structure between the dust cover 6 and the inner ring 2, refer to figure 2 As shown: there is a relief ring groove 21 recessed on both sides of the inner ring 2, an insert ring 62 interspe...

The invention relates to a bearing technology, and discloses an anti-deformation dustproof deep groove ball bearing. The anti-deformation dustproof deep groove ball bearing comprises an outer ring, an inner ring, a retainer and a rolling body, two sides of the inner ring are correspondingly and fixedly provided with a dustproof cover for blocking a gap between the inner ring and the outer ring, each dustproof cover is provided with a supporting structure, each supporting structure comprises an installation ring, inserting grooves and supporting bodies, wherein the installation ring extends on the inner wall of the dustproof cover, the inner ring wall of the installation ring is attached to the outer ring wall of the inner ring, the inserting grooves are formed in the outer ring wall of the installation ring in the circumferential direction at intervals, the supporting bodies are inserted and fixed into the inserting grooves, each supporting body comprises a supporting rod with the lower end partially inserted into the inserting groove, an elastic gasket located at the bottom of the supporting rod and a supporting ball located at the upper end of the supporting rod, an auxiliary roller path allowing the supporting ball to roll is arranged at the position, right opposite to the supporting ball, of the inner ring wall of the outer ring, and a lubricating mechanism for self-lubricating when the supporting ball is in sliding fit with the auxiliary roller path is arranged on the retainer. The bearing has double effects of preventing dust and remarkably increasing radial load, and the service life of the bearing can be effectively prolonged.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a deformation-resistant and dust-proof deep groove ball bearing. Background technique [0002] Deep groove ball bearings, also known as single row radial ball bearings, are the most widely used rolling bearings. They are characterized by small frictional resistance and high speed, and can be used on parts that bear combined loads acting in both radial and axial directions. It is also used on parts bearing axial load. [0003] Existing deep groove ball bearings generally include an outer ring, an inner ring, rolling elements and a cage. After the rolling elements are positioned on the cage, they are in rolling friction fit with the outer ring and the inner ring. Due to its structural characteristics, deep groove ball bearings can withstand a certain radial load. However, once the radial load is too large, it will intensify the degree of wear between the rolling elements and the ...
