Description

Technical Field

[0001] The utility model relates to the technical field of rod end joint bearings, in particular to a rod end joint bearing which has good stability and is easy to assemble. Background Art

[0002] Rod ends are spherical plain bearings. The basic type consists of inner and outer rings with spherical sliding contact surfaces. Rod ends are mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, and can withstand large loads.

[0003] However, in actual use of the above-mentioned equipment, the existing rod end joint bearings generally use traditional rings. Traditional rings are prone to deformation after long-term use, and are not very stable and difficult to install. In view of this, we propose a rod end joint bearing with good stability and easy assembly. Utility Model Content

[0004] The purpose of the present utility model is to provide a rod end joint bearing with good stability and convenient assembly, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a rod end joint bearing with good stability and easy assembly, comprising a bearing outer ring, a washer fixedly connected to the inner wall of the bearing outer ring, a spherical center movably connected to the inner wall of the bearing outer ring, a threaded rod fixedly connected to the lower end of the bearing outer ring, an oil inlet hole formed on the outer wall of the bearing outer ring, and a fixing assembly disposed inside the bearing outer ring, the fixing assembly comprising:

[0006] A card slot is provided on the outer wall of the bearing outer ring, and a latch is provided on the inner wall of the card slot. One end of the latch located inside the bearing outer ring is fixedly connected to an inclined block, and a push block is fitted on the inclined surface of the inclined block;

[0007] The rolling ball is movably connected to the inner wall of the push block, the outer wall of the push block is fixedly connected to the limit plate, the outer wall of the limit plate is fixedly connected to the spring, and the inner wall of the outer ring of the bearing is provided with a ball outlet.

[0008] Preferably, the portion of the ball located inside the push block is larger than the portion of the ball located outside the push block, and the portion of the ball located outside the push block passes through the ball outlet and contacts the center of the ball, so that the ball can rotate freely in the push block and will not fall out of the push block.

[0009] Preferably, the inclined block is provided with an inclined surface at one end close to the push block, and the push block is provided with an inclined surface at one end close to the inclined block that fits with the inclined surface on the inclined block, and the push block passes through and is slidably connected to the ball outlet, so that when the pin is inserted into the slot, the inclined block pushes the push block out through the fit between the inclined surfaces, so that the rolling ball on the push block contacts the center of the contact ball.

[0010] Preferably, the end of the spring away from the limit plate is fixedly connected to the inner wall of the outer ring of the bearing, and the initial state of the spring is a contracted state, so that when the pin leaves the slot, the push block is reset by the spring, so that when the ball center is not installed, the ball can be received on the inner wall of the outer ring of the bearing, thereby preventing the ball from being damaged easily.

[0011] Preferably, there are two groups of the fixing components, which are mirror-imaged at both ends of the bearing outer ring, so that when the pin is inserted into the slot, the balls at both ends can clamp the ball center while promoting its rotation.

[0012] Preferably, the shapes of the pin and the slot are both set to be arc surfaces, and the curvature of the arc surfaces of the pin and the slot is consistent with the curvature of the edge of the bearing outer ring. After the pin is inserted, the axial bearing capacity is increased, making the bearing more effective.

[0013] Compared with the prior art, the present invention provides a rod end joint bearing with good stability and convenient assembly, which has the following beneficial effects:

[0014] 1. This rod end joint bearing has good stability and is easy to assemble. Insert the pin into the slot so that the inclined block can push the push block out through the fit between the inclined surfaces, so that the rolling ball on the push block contacts the contact ball center. The rolling ball and the ball center are both spheres, so the friction generated by the contact between the two is small, making the rotation of the ball center smoother, thereby improving the smoothness of the bearing steering. At the same time, the pin increases the axial bearing capacity, and the fixing components are distributed at both ends of the bearing outer ring, so that the rolling balls at both ends can clamp the ball center while promoting the rotation of the ball center, so that the ball center is better fixed inside the bearing outer ring.

[0015] 2. The rod end joint bearing has good stability and is easy to assemble. The initial state of the spring is a contracted state. When the pin leaves the slot, the push block pulls the limit plate through the spring, thereby resetting the push block. When the ball center is not installed, the ball can be stored on the inner wall of the bearing outer ring, so that the ball is not easily damaged and is convenient for next use.

[0023] In one embodiment of the present invention, a slot 61 is provided on the outer wall of the bearing outer ring 1 , and a latch 62 is provided on the inner wall of the slot 61 . One end of the latch 62 located inside the bearing outer ring 1 is fixedly connected to a bevel block 63 , and a push block 64 is fitted on the bevel surface of the bevel block 63 .

[0025] In addition, the portion of the ball 65 located inside the push block 64 is larger than the portion of the ball 65 located outside the push block 64, and the portion of the ball 65 located outside the push block 64 passes through the ball outlet 68 and contacts the ball center 3, so that the ball 65 can rotate freely in the push block 64 and will not fall out of the push block 64. The ball 65 and the ball center 3 are both spherical, so the friction generated by the contact between the two is small, making the rotation of the ball center 3 smoother.

[0026] In the embodiment of the present utility model, an inclined surface is provided at one end of the inclined block 63 close to the push block 64, and an inclined surface is provided at one end of the push block 64 close to the inclined block 63 that fits with the inclined surface on the inclined block 63, and the push block 64 passes through and is slidably connected to the ball outlet 68, so that when the pin 62 is inserted into the slot 61, the inclined block 63 pushes the push block 64 out through the fit between the inclined surfaces, so that the rolling ball 65 on the push block 64 contacts the contact ball center 3, making the movement of the ball center 3 smoother, thereby improving the smoothness of the bearing steering.

[0027] In an embodiment of the present utility model, one end of the spring 67 away from the limit plate 66 is fixedly connected to the inner wall of the bearing outer ring 1. The initial state of the spring 67 is a contracted state, so that when the pin 62 leaves the slot 61, the push block 64 is reset by the spring 67, so that when the ball center 3 is not installed, the ball 65 can be stored on the inner wall of the bearing outer ring 1, so that the ball 65 is not easily damaged and is convenient for next use.
