Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-strength wear-resistant bearing ring. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotation and reduce the friction coefficient during movement. Bearing rings are annular parts of radial rolling bearings with one or more raceways. Their production generally goes through forging, heat treatment, grinding and other processes. When installing bearing rings, special attention should be paid to the installation sequence. Precision bearings should also pay attention to the positive and negative ends. If installed upside down, it will cause dynamic imbalance and affect the performance of the bearing.

[0003] Most of the bearing rings currently used are two annular structures. After the ball is installed between the two rings, the positioning is completed by the clamping between the structures. Although this method can quickly install the bearing, the bearings are mostly exposed after installation, which will affect the service life of the bearing. When the bearing is used, lubricating oil needs to be added frequently to ensure the normal operation of the ball, which is inconvenient to use. Therefore, a high-strength and wear-resistant bearing ring is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a high-strength wear-resistant bearing ring, which aims to improve the problem in the prior art that the bearing ring causes the ball to be exposed after installation and requires regular lubrication during use.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-strength wear-resistant bearing ring, including ring one, ring one is slidably connected to ring two in the middle, an inner liner block is fixedly connected to the bottom of ring two, an upper groove is provided below the inner liner block, a lower groove is provided at the top of ring one, a ball rack is provided between the lower groove and the upper groove, a clamping block is fixedly connected to the outer side of the bottom of ring two, a clamping groove is provided at the inner bottom of ring one, and the clamping groove and the clamping block are engaged with each other.

[0006] As a further description of the above technical solution:

[0007] An oil injection cavity is formed inside the first and second ferrules after being assembled, and the ball carrier is located in the middle of the oil injection cavity.

[0008] As a further description of the above technical solution:

[0009] A connecting groove is provided at the outer bottom of the second ferrule, and a connecting block is fixedly connected to the outer bottom of the first ferrule, and the connecting block is snap-connected with the connecting groove.

[0010] As a further description of the above technical solution:

[0011] A guide block is fixedly connected to a middle edge of the ferrule.

[0012] As a further description of the above technical solution:

[0013] The inner and outer edges of the bottom of the lining block are both provided with raised parts.

[0014] As a further description of the above technical solution:

[0015] The outer edge of the bottom of the block is provided with an oblique angle, and the oblique angle is matched with the size of an inner edge of the ring.

[0016] As a further description of the above technical solution:

[0017] The first ferrule, the second ferrule and the inner liner block are made entirely of high-strength alloy steel.

[0018] The utility model has the following beneficial effects:

[0019] 1. In the utility model, after aligning the first ferrule and the second ferrule, the ball rack is installed in the middle of the oil filling chamber, and then the first ferrule and the second ferrule are squeezed inwardly. When the clamping block reaches the clamping groove position, the connection between the first ferrule and the second ferrule is completed due to the deformation of the metal, so that the ball rack can be quickly installed, and the operation is simple and fast.

[0020] 2. In the utility model, after the first and second rings are connected, the gap between the first and second rings forms an oil filling chamber. After the lubricating oil is loaded into the oil filling chamber, when the bearing is working, the lubricating oil is blocked by the guide block and the protrusion and is always located in the oil filling chamber, thereby reducing the consumption of the lubricating oil, thereby avoiding frequent filling of the lubricating oil, reducing production costs and increasing the service life of the bearing.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 3 The utility model provides an embodiment: a high-strength wear-resistant bearing ring, including a ring 1, a ring 2 slidably connected to the middle of the ring 1, an inner liner 3 fixedly connected to the bottom of the ring 2, an upper groove 6 is provided below the inner liner 3, a lower groove 7 is provided at the top of the ring 1, a ball rack 4 is provided between the lower groove 7 and the upper groove 6, a clamping block 9 is fixedly connected to the outer side of the bottom of the ring 2, a clamping groove 8 is provided at the bottom of the inner side of the ring 1, the clamping groove 8 and the clamping block 9 are engaged, and an angle is provided on the outer edge of the bottom of the clamping block 9, which is matched with the size of the inner edge of the ring 1; an oil injection cavity 14 is formed inside the ring 1 and the ring 2 2 after being assembled, and the ball rack 4 is located in the middle of the oil injection cavity 14;

[0028] Specifically, after the ball rack 4 is placed on the upper part of the lower groove 7, the ring 1 and the ring 2 2 are connected, and then the connection between the ring 1 1 and the ring 2 2 can be completed by mutual extrusion. Because the ring 2 2 and the inner liner block 3 are installed or made in one piece, when the ring 2 2 moves down, the inner liner block 3 can be driven to move synchronously, thereby realizing the installation of the ball rack 4, and when the clamping block 9 moves down, it will also be deformed by the oblique angle, and rebound when it reaches the position of the clamping groove 8, completing the clamping connection between the ring 1 1 and the ring 2 2. The installation is simple and very convenient, and the oil filling chamber 14 after installation is a relatively sealed space. After the lubricating oil is injected here, the lubricating oil will remain in the oil filling chamber 14 for a long time to lubricate the ball rack 4, thereby increasing the service life of the bearing.

[0029] Reference Figure 2-Figure 3 A connecting groove 12 is provided at the outer bottom of the second ferrule 2, a connecting block 11 is fixedly connected to the outer bottom of the first ferrule 1, the connecting block 11 and the connecting groove 12 are clamped, a guide block 13 is fixedly connected to the middle edge of the first ferrule 1, and a protrusion 10 is provided at the inner and outer edges of the bottom of the liner block 3. The first ferrule 1, the second ferrule 2 and the liner block 3 are made of high-strength alloy steel as a whole;

[0030] Specifically, the connecting groove 12 and the connecting block 11 will also be connected when the ring 1 and the ring 2 are snapped together, so that the upper gap after the ring 1 and the ring 2 are connected can be sealed, thereby further avoiding the leakage of lubricating oil and will not affect the normal operation of the bearing; the guide block 13 at the upper inner edge of the ring 1 and the raised portion 10 behind the bottom outer edge of the inner liner 3 can both reduce the space of the oil filling chamber 14 and extend the path connecting the oil filling chamber 14 with the outside, thereby further reducing the leakage of lubricating oil and thus improving the service life. The ring 1, the ring 2 and the inner liner 3 made of high-strength alloy steel can greatly improve the wear resistance of the bearing ring to adapt to special working environments.

[0031] Working principle: During assembly, first place the ball carrier 4 in the middle of the lower groove 7 on the upper part of the ferrule 1, and store lubricating oil in the middle of the oil filling chamber 14, then align the middle of the ferrule 2 with the middle of the ferrule 1, and then press the ferrule 2 toward the ferrule 1, and then the clamping block 9 enters the middle of the ferrule 1 under the action of the bottom bevel, and squeezes the middle of the ferrule 2, so that the structure of the ferrule 2 is slightly deformed. When the clamping block 9 reaches the position of the clamping groove 8, the clamping block 9 and the clamping groove 8 are plugged in under the action of the elastic deformation of the ferrule 2 itself, so that the bearing can be installed, the operation is simple, and the installation efficiency is greatly improved;

[0032] Secondly, after the lubricating oil is injected into the oil filling chamber 14, after the ring 1 and the ring 2 are snapped together, the oil filling chamber 14 is in a sealed state. At this time, when the bearing is working, the lubricating oil is lubricated in the oil filling chamber 14, and the lubricating oil is blocked by the guide block 13, which can reduce the flow rate entering the gap between the ring 1 and the ring 2, thereby reducing the leakage of the lubricating oil from the gap. Secondly, the protrusion 10 will also guide the lubricating oil to the middle part, so as to ensure the lubrication operation of the lubricating oil on the ball cage 4.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
