Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of bearings, in particular to a wear-resistant bearing ring. Background Art
[0002] Bearings are an important part of modern mechanical equipment. Generally, bearing rings are set on the outer periphery of bearings. Bearing rings are auxiliary parts used to fix bearings so that they can be correctly installed on shafts or seat plates. At the same time, bearing rings can also help bearings reduce wear and friction when rotating, and increase the durability and service life of bearings.
[0003] When traditional bearing rings are in use, the contact surfaces between the bearing rings and the bearings are often rubbed against each other, which makes the contact surfaces between the bearing rings and the bearings easily wear, resulting in a poor service life of the bearing rings. The prior art reduces the friction between the bearings and the bearing rings by arranging beads on the inner diameter side walls of the bearing rings and opening an oil storage tank in the bearing rings for adding lubricating oil. However, the beads are easily worn during use, so that the bearings directly rub against the bearing rings, causing damage to the bearing rings. Furthermore, the worn beads are not easy to remove from the bearing rings, making it inconvenient to replace the worn beads. Utility Model Content
[0004] In view of the above problems existing in the prior art, the utility model aims to provide a wear-resistant bearing ring in which the bearing does not immediately contact the bearing ring after the rotating ball is worn and the rotating ball can be quickly replaced.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wear-resistant bearing ring, including a bearing ring body, a liquid storage tank is formed in the bearing ring body, a plurality of rotating balls are rotatably arranged on the inner wall of the bearing ring body, any one of the rotating balls partially enters the liquid storage tank, a connecting rod is arranged on the rotating ball, a plurality of buffer blocks are also arranged on the inner wall of the bearing ring body, a fixing ring is respectively arranged at both ends of the bearing ring body, and a liquid inlet is arranged on the outer wall of the bearing ring body.
[0006] Preferably, the liquid storage tank is an annular groove, and a plurality of limit frames are fixed on the inner diameter side wall of the liquid storage tank. The limit frames are the same in number as the rotating balls and correspond one to one. The limit frames fit tightly with the rotating balls to limit the radial outward movement of the rotating balls.
[0007] Furthermore, the limiting frame is a curved cross, and the rotating ball is exposed in the liquid storage tank through the limiting frame. The structural setting of the limiting frame enables the rotating ball to contact the lubricating liquid in the liquid storage tank.
[0008] Preferably, a connecting hole is opened between the two axial ends of any of the rotating beads, and a socket is formed at a position corresponding to one end of the bearing ring body and any of the connecting holes. Any of the connecting rods passes through the corresponding socket and the connecting hole in sequence, and the rotating ball is restricted by the connecting rod to rotate with the connecting rod as the rotating axis.
[0009] Preferably, the number of the buffer blocks is the same as that of the rotating balls, and any one of the buffer blocks is located between two adjacent rotating balls. A portion of the buffer block is radially embedded in the bearing ring body, and another portion of the buffer block protrudes radially inward, and the inner protrusion length does not exceed the inner protrusion length of the rotating balls. Through the structural setting of the buffer block, the buffer block assists the rotating balls to avoid frictional contact between the bearing ring body and the bearing.
[0010] Preferably, snap-fitting protrusions are formed at both axial ends of any one of the buffer blocks, and a plurality of snap-fitting grooves matching the buffer blocks are formed on the side of any one of the fixing rings facing the bearing ring body, and the snap-fitting grooves correspond to the same number of buffer blocks one-to-one, and the buffer block is fixed relative to the bearing ring body through the snap-fitting protrusions and the snap-fitting grooves.
[0011] Preferably, a plurality of fixing holes are distributed in a circular array at both axial ends of the bearing ring body, and the same number of fixing bolts are penetrated through any one of the fixing rings.

[0012] Preferably, the liquid inlet is communicated with the liquid storage tank, the inner wall of the liquid inlet is threaded, a sealing bolt is threadedly connected along the inner wall of the liquid inlet, and the liquid storage tank is opened or sealed by the sealing bolt.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The rotating ball is assisted by the buffer block on the inner wall of the bearing ring body. When the surface of the rotating ball is worn, the bearing and the buffer block are in friction contact, so that the bearing does not directly contact the bearing ring body. The rotating ball and the buffer block are replaced according to the wear condition to continuously maintain the friction between the bearing ring and the bearing. The bearing ring is highly durable, and the buffer block and the rotating ball are detachably connected to the bearing ring body through a connecting rod and a fixed ring, which is convenient for replacing worn buffer blocks and rotating balls and is easy to use.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example 1
[0025] like Figures 1 to 4 As shown, it includes a bearing ring body 1, a liquid storage tank 7 is formed in the bearing ring body 1, five rotating balls 6 are rotatably arranged on the inner wall of the bearing ring body 1, and any one of the rotating balls 6 partially enters the liquid storage tank 7. A connecting rod 13 is arranged on the rotating ball 6, and five buffer blocks 3 are also arranged on the inner wall of the bearing ring body 1. A fixing ring 2 is respectively arranged at both ends of the bearing ring body 1, and four fixing holes 11 are distributed in a circular array on the axial ends of the bearing ring body 1. Four fixing bolts 4 are penetrated and arranged on any one of the fixing rings 2. The four fixing bolts 4 are threadedly connected to the four fixing holes 11 in a one-to-one correspondence. A liquid inlet 14 is arranged on the outer wall of the bearing ring body 1, and the liquid inlet 14 is connected to the liquid storage tank 7. The inner wall of the liquid inlet 14 is threaded, and a sealing bolt 5 is threadedly connected along the inner wall of the liquid inlet 14.
[0026] The liquid storage tank 7 is an annular groove surrounding the circumference of the bearing ring body 1. Five limit frames 8 are fixed on the inner diameter side wall of the liquid storage tank 7. Any one of the limit frames 8 is a curved cross. The limit frame 8 bends along the surface of the rotating ball 6 toward the inside of the bearing ring body 1. The five limit frames 8 correspond to the five rotating balls 6 one by one. The two corresponding limit frames 8 are tightly fitted with the rotating balls 6 to limit the radial outward movement of the rotating balls 6. The rotating balls 6 are exposed in the liquid storage tank 7 through the limit frames 8.
[0027] A connecting hole 15 is opened between the axial ends of any rotating ball 6, and a plug hole 12 is formed at a position corresponding to one end of the bearing ring body 1 and any connecting hole 15. Any connecting rod 13 passes through the corresponding plug hole 12 and the connecting hole 15 in sequence to limit the rotating ball 6 to rotate with the connecting rod 13 as the rotating axis.
[0028] The buffer block 3 is made of rubber, and the number of the buffer blocks 3 is also five. Any one of the buffer blocks 3 is located between two adjacent rotating balls 6. A portion of the buffer block 3 is embedded in the bearing ring body 1 radially outward, and another portion of the buffer block 3 protrudes radially inward, and the inner convex length does not exceed the inner convex length of the rotating ball 6. The buffer block 3 is embedded in the bearing ring body 1 at both axial ends to form a snap-in protrusion 9. Any one of the fixed rings 2 has five snap-in grooves 10 that fit with the buffer block 3 on its side facing the bearing ring body 1. The five snap-in grooves 10 correspond one-to-one to the five buffer blocks 3. The buffer block 3 is fixed relative to the bearing ring body 1 through the snap-in protrusion 9 and the snap-in groove 10 to avoid direct contact between the bearing ring body 1 and the bearing.
[0029] The implementation principle of the embodiment 1 of the present application is as follows: when the bearing ring is used, the sealing bolt 5 is first taken out, the lubricating liquid is injected into the liquid storage tank 7 along the liquid inlet 14, and then the sealing bolt 5 is reinserted, and the bearing ring body 1 is rotated so that the lubricating liquid contacts the five rotating balls 6 under the action of gravity, and then the bearing ring is directly sleeved on the bearing surface, and the outer wall of the bearing contacts the five rotating balls 6 movably, and when the bearing rotates, the rotating balls 6 rotate around the connecting rod 13, thereby increasing the friction between the bearing and the bearing ring;
[0030] When the surface of the rotating ball 6 is worn, the bearing will tilt toward the worn part and make frictional contact with the buffer block 3 in that direction. The buffer block 3 prevents the bearing from directly contacting the bearing ring body 1 before sufficient frictional loss occurs, and the bearing ring body 1 is not easy to wear.
[0031] When it is necessary to replace the rotating ball 6 and the buffer block 3, first take out all the fixing bolts 4 to release the fixing rings 2 at both ends from the bearing ring body 1. After taking out the fixing ring 2, the buffer block 3 is also released relative to the bearing ring body 1 and can be directly replaced, and one end of the clamping protrusion 9 is exposed outside the bearing ring body 1. Further pulling out the clamping protrusion 9 allows the rotating ball 6 to move radially between the limit frame 8 and the axis, thereby replacing the rotating ball 6. Re-insert the clamping protrusion 9, the fixing ring 2 and the fixing bolts 4 to fix the buffer block 3 and the rotating ball 6 again. The replacement process is simple and easy to use.
[0032] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the basic features of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
