Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing technology, and in particular relates to a precision bearing structure that improves structural strength performance. Background Technology
[0002] Bearings are essential components in modern machinery, used to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. Based on the shape of the rolling elements, rolling bearings are divided into two main categories: ball bearings and roller bearings. In mechanical products, bearings are considered high-precision products.
[0003] Currently, after prolonged use, the lubricating oil on the surface of the bearing balls evaporates, leading to increased friction between the balls and the outer and inner rings of the precision bearing, thus affecting the bearing's service life. Therefore, we have proposed a precision bearing structure that improves structural strength. During operation, lubricating oil is applied to the surface of the balls to reduce friction between them and the outer and inner rings, extending the bearing's service life and increasing its strength.
[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this invention is to provide a precision bearing structure that improves structural strength. This solves the problem that after prolonged use, the lubricating oil on the surface of the bearing balls evaporates, leading to increased friction between the balls and the outer and inner rings of the precision bearing, thus affecting the bearing's service life.
[0006] To achieve the above objectives, this utility model proposes a precision bearing structure with improved structural strength performance. The structure comprises a precision bearing outer ring and a precision bearing inner ring, the inner ring being disposed inside the outer ring. A plurality of balls are uniformly rotatably connected between the outer and inner rings. Reinforcing rings are movably installed on both the left and right sides of the outer and inner rings. Two mounting rings are fixedly connected to one side of each reinforcing ring, and an oil-absorbing sponge ring is movably fitted inside each mounting ring.
[0007] In one example, a retainer is sleeved between the outer surfaces of several of the balls, and a limit ring is fixedly connected to both the inner and outer circular walls of the reinforcing ring.
[0008] In one example, the top and bottom surfaces inside the mounting ring are fixedly connected with retaining rings, and a circular groove is provided on one side of the mounting ring.
[0009] In one example, both the inner and outer circular walls of the oil-absorbing sponge ring are provided with slots, and the retaining ring is movably fitted into the slots.
[0010] In one example, both the inner wall surface of the outer ring of the precision bearing and the outer wall surface of the inner ring of the precision bearing are provided with grooves.
[0011] In one example, a number of through holes are provided on one side of the reinforcing ring.
[0012] In one example, one side of the oil-absorbing sponge ring is in contact with the outer wall of the ball.
[0013] The precision bearing structure proposed in this invention, which improves structural strength, can bring the following benefits:
[0014] Beneficial effects:
[0015] By installing reinforcing rings, the stability between the outer and inner rings of the precision bearing is increased when the two reinforcing rings are rotated and installed between them, thereby improving the structural strength between the outer and inner rings. When one side of the oil-absorbing sponge ring is in contact with the outer wall of the ball, the ball will come into contact with the oil-absorbing sponge ring during rotation. The lubricating oil in the oil-absorbing sponge ring can be applied to the surface of the ball, achieving timely lubrication of the ball. This reduces the friction between the ball and the outer and inner rings of the precision bearing, increases the service life of the ball, and improves the rotational performance of the bearing.
[0016] By setting up an oil-absorbing sponge ring, when the operator fixes the oil-absorbing sponge ring inside the mounting ring and adds lubricating oil to the mounting ring, the oil-absorbing sponge ring absorbs the lubricating oil. Since the reinforcing ring is movably installed between the outer ring and the inner ring of the precision bearing, the operator can disassemble the reinforcing ring to replace the oil-absorbing sponge ring after long-term use, thus preventing the oil-absorbing sponge ring from wearing out after long-term use and failing to lubricate the balls in time.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] like Figures 1-4 As shown, this utility model proposes a precision bearing structure to improve structural strength, comprising a precision bearing outer ring 1 and a precision bearing inner ring 2. To improve the structural strength of the precision bearing, firstly, the precision bearing inner ring 2 is placed inside the precision bearing outer ring 1. A plurality of balls 3 are evenly rotatably connected between the precision bearing outer ring 1 and the precision bearing inner ring 2. Grooves are formed on the inner wall of the precision bearing outer ring 1 and the outer wall of the precision bearing inner ring 2 to facilitate the rolling of the balls 3 between the precision bearing outer ring 1 and the precision bearing inner ring 2. A retainer 4 is fitted around the balls 3, allowing the balls 3 to roll evenly. The balls 3 are fixed between the outer ring 1 and the inner ring 2 of the precision bearing to prevent them from falling out. At the same time, they prevent the balls 3 from colliding and rubbing against each other during operation, reducing the wear and heat generation of the balls 3, thereby extending the service life of the balls 3. Reinforcing rings 5 are movably installed on both the left and right sides between the outer ring 1 and the inner ring 2 of the precision bearing. The two reinforcing rings 5 can increase the stability between the outer ring 1 and the inner ring 2 of the precision bearing. Limiting rings 6 are fixedly connected to the inner and outer circular walls of the reinforcing rings 5. Several through holes are opened on one side of the reinforcing rings 5 so that the heat between the outer ring 1 and the inner ring 2 of the precision bearing can flow out through the through holes.
[0029] Specifically, two mounting rings 7 are fixedly connected to one side of the reinforcing ring 5. A circular groove is opened on one side of the mounting ring 7. The top and bottom surfaces of the mounting ring 7 are fixedly connected to retaining rings 8. An oil-absorbing sponge ring 9 is movably sleeved inside the mounting ring 7. One side of the oil-absorbing sponge ring 9 is in contact with the outer wall of the ball 3. When the operator fixes the oil-absorbing sponge ring 9 inside the mounting ring 7 and adds lubricating oil to the mounting ring 7, the oil-absorbing sponge ring 9 absorbs the lubricating oil. When the ball 3 rotates between the outer ring 1 and the inner ring 2 of the precision bearing, the ball 3 will come into contact with the oil-absorbing sponge ring 9 during the rotation. The lubricating oil in the oil-absorbing sponge ring 9 can be applied to the surface of the ball 3 to achieve timely lubrication of the ball 3, thereby reducing the friction between the ball 3 and the outer ring 1 and the inner ring 2 of the precision bearing and improving the service life of the ball 3.
[0030] Specifically, the inner and outer circular walls of the oil-absorbing sponge ring 9 are provided with slots 10. When the retaining ring 8 and the slot 10 are movably fitted together, the oil-absorbing sponge ring 9 can be fixed inside the mounting ring 7. At the same time, since the reinforcing ring 5 is movably installed between the outer ring 1 and the inner ring 2 of the precision bearing, the operator can disassemble the reinforcing ring 5 to replace the oil-absorbing sponge ring 9 after long-term use, so as to avoid the oil-absorbing sponge ring 9 from wearing out after long-term use and failing to lubricate the ball 3 in time.
[0031] Working Principle: To improve the structural strength of this precision bearing, two reinforcing rings 5 are first movably installed on the left and right sides between the outer ring 1 and the inner ring 2 of the precision bearing. This increases the stability between the outer ring 1 and the inner ring 3, thereby enhancing the structural strength between them. When the operator fixes the oil-absorbing sponge ring 9 inside the mounting ring 7 and adds lubricating oil to the mounting ring 7, the oil-absorbing sponge ring 9 absorbs the lubricating oil. During rotation, the ball 3 comes into contact with the oil-absorbing sponge ring 9, and the lubricating oil in the oil-absorbing sponge ring 9 can be applied to the surface of the ball 3, achieving timely lubrication of the ball 3. This reduces the friction between the ball 3 and the outer and inner rings of the precision bearing, thus improving the rotational performance of the bearing. Since the reinforcing rings 5 are movably installed between the outer ring 1 and the inner ring 2 of the precision bearing, the operator can disassemble the reinforcing rings 5 to replace the oil-absorbing sponge ring 9 after long-term use, preventing wear and tear on the oil-absorbing sponge ring 9 that would prevent it from failing to lubricate the ball 3 in a timely manner.
