Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and more specifically, to a high load-bearing deep groove ball bearing. Background Technology

[0002] Deep groove ball bearings are a type of rolling bearing widely used in various mechanical transmission systems. Their unique feature is the deep, continuous raceways on both the inner and outer rings, within which rolling balls (spherical rolling elements) are housed and secured by a cage. This design allows the balls to roll freely within the raceways, and because the raceway depth is close to the ball diameter, deep groove ball bearings can effectively withstand radial loads and also possess a certain axial load support capacity. Due to their low frictional resistance and high speed capability, deep groove ball bearings are widely used in automotive manufacturing, the motor industry, home appliances, machine tools, agricultural machinery, and many other industrial production equipment that primarily bear radial loads.

[0003] However, traditional deep groove ball bearings also face some challenges in practical applications. Since they primarily rely on internal balls to bear the load, under high load conditions, the balls may deform or wear more rapidly, leading to abnormal noise or malfunction. Furthermore, over time, dust, moisture, and other contaminants can penetrate the bearing, further exacerbating wear and fatigue, affecting its performance, and shortening its service life.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0010] Furthermore, in order to improve the bearing's load-bearing capacity and effectively prevent misalignment between the outer and inner rings, the retaining assembly includes a cage disposed between the two sets of balls, with limit rods provided at both ends of the cage. The retaining assembly also includes a first limit groove on one side of the first slide groove and a second limit groove on one side of the second slide groove, and both the first and second limit grooves cooperate with the limit rods.

[0011] Furthermore, in order to secure the protective shell and protect the bearing from direct impact and potential damage from external objects, the fixing assembly includes fixing grooves symmetrically opened on the outer circumference of the outer ring, and the fixing assembly also includes limiting holes symmetrically opened on the outer circumference of the protective shell, and the limiting holes and fixing grooves are engaged by fixing rods.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the high load-bearing deep groove ball bearing according to an embodiment of the present utility model includes an outer ring 1, an inner ring 2 is provided inside the outer ring 1, the outer ring 1 and the inner ring 2 are engaged by a plurality of balls 3, and the two sets of balls 3 are engaged by a retaining component 4; a protective shell 5 is provided on both sides of the outer ring 1, a sealing ring 6 is provided on the side of the protective shell 5 near the outer ring 1, and the protective shell 5 and the outer ring 1 are engaged by a fixing component 7.

[0027] By utilizing the above-mentioned technical solution of this utility model, through the cooperation of the protective shell 5 and the sealing ring 6, not only can impurities such as dust, water droplets and small particles be effectively prevented from entering the bearing, protecting the bearing from direct impact and potential damage from external objects, but also the grease inside the bearing can be prevented from leaking out, ensuring that the bearing always maintains a good lubrication state.

[0030] In one embodiment, the retaining assembly 4 includes a retainer 401 disposed between two sets of balls 3. Both ends of the retainer 401 are provided with limit rods 402. The retaining assembly 4 also includes a first limit groove 403 opened on one side of the first slide groove 8 and a second limit groove 404 opened on one side of the second slide groove 9.

The cooperation of the protective shell 5 and the sealing ring 6 effectively prevents dust, water droplets, and small particles from entering the bearing, protecting it from direct impact and potential damage from external objects, and also prevents the leakage of lubricating grease from the bearing, ensuring that the bearing always maintains good lubrication.
