Description

Technical Field

[0001] The utility model relates to the field of roller bearings, in particular to a compression-resistant and crack-resistant roller bearing component. Background Art

[0002] A roller bearing is a bearing that can withstand large axial loads, radial loads and overturning moments at the same time. Each roller bearing can withstand a load corresponding to the width of the outer ring. Different types of roller bearing components are used according to the needs of the equipment. Existing roller bearing components, during use, use rolling elements to roll between the inner and outer rings to reduce friction between mechanical parts. Since the lubricant is applied to the ball bearing through a syringe or lubricant reservoir each time, its lubricating permeability is not strong, which affects the friction of the internal ball bearing and causes it to crack and damage. Therefore, we have proposed a pressure-resistant and crack-resistant roller bearing component to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that the existing roller bearing parts, since the lubricant is applied to the ball bearings through a syringe or a lubricant reservoir each time, the lubricant penetration is not strong, which affects the friction of the internal ball bearings.

[0004] The technical solution of the utility model is: a pressure-resistant and crack-resistant roller bearing component, comprising an inner ring, an outer ring, a rolling cage, balls, guide blocks and a reinforcement sleeve; the outer side of the inner ring is sleeved with a rolling cage for retaining and separating balls, the outer side of the rolling cage is sleeved with an outer ring for supporting the rotation of the internal rolling cage, the outer side of the outer ring is surrounded by a guide block for maintaining the guide rotation, and a reinforcement sleeve for reinforcing the roller bearing against pressure is circumferentially arranged between the inner ring and the rolling cage.

[0005] Preferably, as the rolling cage drives the internal ball to rotate, the flow hole is connected to the reinforcement sleeve column, and the lubricating oil can quickly pass through the penetration hole, the slideway and the flow hole, thereby increasing the overall rapid lubrication and the mutual friction. When an external force impacts, it first passes through the anti-collision ring for isolation, then passes through the reinforcement sleeve column for shock absorption, and finally passes through the anti-sway ring on the ball sleeve for anti-sway protection, forming a three-stage protection operation to enhance the overall pressure resistance effect.

[0006] Preferably, a sleeve hole is provided in the middle of the inner ring, and connecting through holes for oil flow are provided around the inner wall of the sleeve hole. Anti-collision rings for protecting the inner ring are provided at both ends of the sleeve hole. An inflow hole for oil to enter is provided in the middle of the reinforcement sleeve column. When the integral bearing component stops being disassembled, the filling operation is performed directly through the inflow hole on the reinforcement sleeve column.

[0007] Preferably, a central reinforcement ring is provided in the middle of the rolling cage, and ball sleeves for carrying balls are provided around the edges on both sides of the rolling cage. A spherical groove is provided in the middle of the ball sleeve. As the rolling cage drives the ball to rotate, the ball is located in the spherical groove of the ball sleeve for limited rolling.

[0008] Preferably, an anti-sway ring is provided at the opening of the spherical groove, and flow holes are evenly distributed on the bottom of the spherical groove. The flow holes are connected to the reinforcement sleeve column, and the lubricating oil can quickly pass through the penetration holes, slideways and flow holes to increase the overall rapid lubrication.

[0009] Preferably, an access channel is opened at the outer end of the central reinforcement ring, and multiple groups of access channels are arranged around the outer end of the central reinforcement ring. When the integral roller bearing rotates, the oil is directly dripped onto the outer ring, gradually penetrates downward through the penetration hole, and passes through the slideway, ball sleeve, flow hole and connecting through hole in turn, gradually lubricating the whole.

[0010] Preferably, the inner wall of the outer ring is provided with a slideway for the rotation of the rolling cage, and the outer wall of the outer ring is provided with penetration holes. There are multiple groups of penetration holes, which are distributed around the outer wall of the outer ring. The oil passes through the annular penetration holes and enters the interior in multiple directions for rapid lubrication.

[0011] Preferably, multiple groups of guide blocks are provided, and the multiple groups of guide blocks are circumferentially distributed along the two side edges of the outer ring. The outer wall of the guide block is covered with a shock-absorbing rubber layer, and the interior of the shock-absorbing rubber layer is provided with a shock-absorbing damper. As the overall outer ring rotates, the guide blocks are driven to rotate, which facilitates external observation of whether the roller bearing is deviated, thereby reducing the damage of the deviation to the internal friction.

[0012] Beneficial effects of the utility model:

[0013] 1. Different from the previous method of applying lubricant to the ball bearing directly by using a direct syringe or lubricant reservoir, the reinforced sleeve can directly guide the lubricating oil into the roller bearing through the inflow hole, thereby increasing the overall lubricity. As the rolling cage drives the internal balls to rotate, the flow hole is connected to the reinforced sleeve, and the lubricating oil can quickly pass through the penetration hole, the slideway and the flow hole, thereby increasing the overall rapid lubricity, increasing the mutual friction, and greatly improving the overall crack resistance.

[0014] 2. As the overall outer ring rotates, the guide block is driven to rotate as well, making it easier to observe from the outside whether the roller bearing is deflected, thereby reducing the damage caused by deflection to the internal friction. The ball sleeve rotates along the slideway, increasing the guide rotation stroke and providing rolling limit protection for the ball. When external force impacts, it is first separated by the anti-collision ring, then shock-absorbing by the reinforced sleeve column, and finally anti-sway protection by the anti-sway ring on the ball sleeve, forming a three-stage protection operation to enhance the overall pressure resistance.

The outer wall of the guide block 201 is coated with a shock-absorbing rubber layer, and a shock-absorbing damping is provided inside the shock-absorbing rubber layer. As the outer ring 2 rotates, the guide block 201 is driven to rotate, which is convenient for external observation of whether the roller bearing is deflected, thereby reducing the damage of the deflection to the internal friction.

[0023] See also Figure 2-3 In this embodiment, a sleeve hole is provided in the middle of the inner ring 1, and a connecting through hole 101 for oil flow is provided around the inner wall of the sleeve hole, and anti-collision rings 104 for protecting the inner ring 1 are provided at both ends of the sleeve hole, and an inflow hole 103 for oil to enter is provided in the middle of the reinforcement sleeve column 102.

A spherical groove is provided in the middle of the ball sleeve 301. As the rolling cage 3 drives the balls 4 to rotate, the balls 4 are located in the spherical grooves in the ball sleeve 301 for limited rolling.

[0024] See also Figure 3-4 In this embodiment, an anti-sway ring 305 is sleeved at the opening of the spherical groove, and flow holes 304 are evenly distributed at the bottom of the spherical groove. The flow holes 304 are connected to the reinforcement sleeve 102, and the lubricating oil can quickly pass through the penetration holes 202, the slideway 203 and the flow holes 304, thereby increasing the overall rapid lubrication.

[0028] When external force impacts, it is first blocked by the anti-collision ring 104, then transmitted to the reinforcement sleeve column 102, and finally protected by the anti-sway ring 305 on the ball sleeve 301.

When an external force impacts, it first passes through the anti-collision ring 104 for isolation, then passes through the reinforcement sleeve 102 for shock absorption, and finally passes through the anti-sway ring 305 on the ball sleeve 301 for anti-sway protection, forming a three-stage protection operation to enhance the overall pressure resistance effect.
