Description

Technical Field

[0001] The utility model belongs to the field of bearings and relates to a deep groove ball bearing, in particular to a high-load deep groove ball bearing. Background Art

[0002] Deep groove ball bearings are important components widely used in mechanical systems to support loads on rotating shafts. However, under conditions of long-term high-speed rotation or heavy loads, the lubricity of the balls in traditional deep groove ball bearings decreases, and the friction coefficient between the balls and the inner and outer rings of the bearings increases, which easily generates operating noise and reduces the performance and life of the bearings. Summary of the Invention

[0003] The purpose of the utility model is to provide a high-load deep groove ball bearing with self-lubrication and reduced friction coefficient to solve the above problems in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A high-load deep groove ball bearing, comprising a bearing inner ring, balls, a cage and a bearing outer ring, characterized in that the balls are located between the bearing inner ring and the bearing outer ring, and a load-bearing mechanism for reducing the ball friction coefficient and having self-lubrication is provided between the bearing inner ring and the bearing outer ring;

[0005] The outer wall of the bearing inner ring and the inner wall of the bearing outer ring are both provided with annular grooves for rolling movement;

[0006] The cross section of the ring groove is arranged in an arc structure and is movably connected with the ball;

[0007] The bearing mechanism includes a first wear-resistant ring and a second wear-resistant ring for improving the self-lubricating effect of the balls and reducing the friction coefficient of the balls;

[0008] The cross-sections of the wear-resistant ring 1 and the wear-resistant ring 2 are both arranged in an arc structure, and are symmetrically mounted in the ring grooves of the bearing inner ring and the bearing outer ring respectively;

[0009] A plurality of rolling bodies capable of reducing the ball friction coefficient are arranged on the corresponding side surfaces of the wear-resistant ring 1 and the wear-resistant ring 2, and the rolling bodies can be rollingly connected to the corresponding side walls of the wear-resistant ring 1 and the wear-resistant ring 2.

[0010] In the above-mentioned high-load deep groove ball bearing, a plurality of rolling elements are arranged in sequence along the inner circumferential wall of the first wear-resistant ring and the outer circumferential wall of the second wear-resistant ring in a circumferential direction and roll in contact with the balls.

[0011] In the above-mentioned high-load deep groove ball bearing, the rolling element may be a nano ball, and the rolling element may roll through the movement of the ball.

[0012] Compared with the existing technology, this high-load deep groove ball bearing has a simple structural design. Wear-resistant ring 1 and wear-resistant ring 2 are respectively embedded and installed in the ring grooves of the inner ring and outer ring of the bearing. The rolling elements on the wear-resistant ring 1 and the wear-resistant ring 2 fit in and roll with the balls, thereby reducing the friction coefficient. The rolling elements are nano-spheres, which have a self-lubricating effect and extend the performance and life of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 、 Figure 2 、 Figure 3 As shown, the high-load deep groove ball bearing includes a bearing inner ring 1, balls 3, a retainer 4 and a bearing outer ring 2. The balls 3 are located between the bearing inner ring 1 and the bearing outer ring 2. A bearing mechanism for reducing the friction coefficient of the balls 3 and having self-lubrication is provided between the bearing inner ring 1 and the bearing outer ring 2. An annular groove 8 for rolling activity is provided on the outer wall of the bearing inner ring 1 and the inner wall of the bearing outer ring 2. The cross-section of the annular groove 8 is arranged in an arc structure and is movably connected to the balls 3. The bearing mechanism includes a wear-resistant ring 1 5 and a wear-resistant ring 2 6 for improving the self-lubrication effect of the balls 3 and reducing the friction coefficient of the balls 3. The cross-sections of the wear-resistant ring 1 5 and the wear-resistant ring 2 6 are both arranged in an arc structure. The wear-resistant rings 1 and 2 are symmetrically mounted in the annular grooves 8 of the bearing inner ring 1 and the bearing outer ring 2, respectively. The corresponding sides of the wear-resistant rings 1 and 2 are provided with a plurality of rolling bodies 7 that can reduce the friction coefficient of the balls 3. The rolling bodies 7 can be rollingly connected to the corresponding side walls of the wear-resistant rings 1 and 2. The above-mentioned structure is simple in design. The wear-resistant rings 1 and 2 are respectively mounted in the annular grooves 8 of the bearing inner ring 1 and the bearing outer ring 2, and the rolling bodies 7 on the wear-resistant rings 1 and 2 are in contact with the balls 3 to reduce the friction coefficient. The rolling bodies 7 are nano-spheres, which have a self-lubricating effect and extend the bearing performance and life.

[0019] To elaborate further, a number of rolling bodies 7 are arranged in sequence along the inner circumferential wall of the wear-resistant ring 1 5 and the outer circumferential wall of the wear-resistant ring 2 6 in a circumferential direction, and roll in contact with the ball 3. The rolling body 7 can be a nano-ball, and the rolling body 7 can move through the ball 3, thereby rolling. The full name of the nano-ball is "atomic self-assembled nano-ball solid lubricant", which is an aluminum-based alloy component with an icosahedral atomic cluster structure and is processed using a unique nano-preparation process. It is a nano-scale lubricant and can reduce noise.
