Description

Technical Field

[0001] The utility model relates to the technical field of spherical plain bearings, in particular to a fiber-wound composite spherical plain bearing. Background Technique

[0002] A spherical plain bearing is a spherical sliding bearing with a variety of special process treatment methods, such as surface phosphating, flanging, padding, spraying, etc., to meet different mechanical motion requirements. The main feature of a spherical plain bearing is that its sliding contact surface consists of an inner spherical surface and an outer spherical surface, which allows it to rotate and swing at any angle during motion. This bearing design gives it characteristics such as large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, and good lubrication. Fiber-wound composite materials are applied to spherical plain bearings due to their high specific strength, high specific stiffness, lightweight, high production efficiency, low cost, and good corrosion resistance. Existing fiber-wound composite spherical plain bearings usually need to be regularly lubricated with oil to ensure normal operation. For spherical plain bearings with relatively frequent use, the frequency of adding lubricating oil is even higher, which is rather cumbersome and very inconvenient. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the utility model provides a fiber-wound composite spherical plain bearing to solve the problems presented in the above background technique.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: A fiber-wound composite spherical plain bearing, including a mounting seat, a buffer pad is fixedly connected to the top of the mounting seat, a bearing seat is fixedly connected to the upper surface of the buffer pad, an outer ring is fixedly connected to the inner surface of the bearing seat, an inner ring is arranged on the inner surface of the outer ring, a first screw hole is arranged at the top of the bearing seat, a second screw hole is arranged at the top of the outer ring, and an oil injection mechanism is arranged inside the first screw hole and the second screw hole. The oil injection mechanism includes an oil injection cylinder body, a sponge layer is arranged on the inner surface of the oil injection cylinder body, a fixing rod and a second guide plate are fixedly connected to the inner surface of the oil injection cylinder body, a first guide plate is fixedly connected to the top end of the fixing rod, and an oil passage port is arranged at the middle of the inside of the first guide plate.

[0005] Preferably, the first screw hole is arranged directly above the second screw hole, and the outer surface of the oil injection cylinder body is threadedly connected to the inner surfaces of the first screw hole and the second screw hole.

[0006] Preferably, the inside of the first screw hole is communicated with the inside of the second screw hole, and the buffer pad is made of rubber material.

[0007] Preferably, an oil injection port is arranged at the top of the oil injection cylinder body, and a top plug is arranged inside the oil injection port.

[0008] Preferably, the sponge layer is disposed directly above the first guide plate, and the first guide plate is disposed directly above the second guide plate.

[0009] Advantageous Effects

[0010] The present utility model provides a fiber-wound composite spherical plain bearing. It has the following advantageous effects:

[0011] (1) For this fiber-wound composite spherical plain bearing, through the oil injection mechanism, by utilizing the structure of the sponge layer and the first guide plate and the second guide plate with a gentle inclined upper surface, a relatively large amount of lubricating oil can be added into the oil injection cylinder each time, enabling the lubricating oil to enter between the outer ring and the inner ring at a slow flow rate and in a small amount. This can ensure continuous lubrication of the spherical plain bearing, and the lubricating oil is not likely to seep out, without causing waste. It is suitable for spherical plain bearings with relatively frequent use, can reduce the frequency of adding lubricating oil, and is more convenient.

[0012] (2) For this fiber-wound composite spherical plain bearing, through the provided buffer pad, the elasticity of the rubber material can be used to weaken vibrations, thereby reducing the vibrations received by the bearing housing, and thus extending the service life of the spherical plain bearing.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Embodiment 1:

[0019] As Figures 1-3As shown in the figure, the utility model provides a fiber-wound composite spherical plain bearing, which comprises a mounting seat 1. A buffer pad 2 is fixedly connected to the top of the mounting seat 1. A bearing seat 3 is fixedly connected to the upper surface of the buffer pad 2. An outer ring 4 is fixedly connected to the inner surface of the bearing seat 3. An inner ring 5 is arranged on the inner surface of the outer ring 4. A first screw hole 6 is arranged on the top of the bearing seat 3. A second screw hole 7 is arranged on the top of the outer ring 4. An oil injection mechanism 8 is arranged inside the first screw hole 6 and the second screw hole 7. The oil injection mechanism 8 comprises an oil injection cylinder body 81. A sponge layer 84 is arranged on the inner surface of the oil injection cylinder body 81. A fixing rod 85 and a second guide plate 87 are fixedly connected to the inner surface of the oil injection cylinder body 81. The top end of the fixing rod 85 is fixedly connected to a first guide plate 86. An oil through hole 88 is arranged in the middle of the first guide plate 86.

[0020] Specifically, the first screw hole 6 is arranged directly above the second screw hole 7. The outer surface of the oil injection cylinder body 81 is threadedly connected to the inner surfaces of the first screw hole 6 and the second screw hole 7.

[0021] Specifically, the inside of the first screw hole 6 is communicated with the inside of the second screw hole 7. The buffer pad 2 is made of rubber material.

[0022] Specifically, an oil injection port 82 is arranged on the top of the oil injection cylinder body 81. A top plug 83 is arranged inside the oil injection port 82.

[0023] Specifically, the sponge layer 84 is arranged directly above the first guide plate 86. The first guide plate 86 is arranged directly above the second guide plate 87.

[0024] The working principle and beneficial effects of the above embodiments.

[0025] During use, after initially installing the spherical plain bearing, lubricating oil is injected through the first screw hole 6 and the second screw hole 7 to lubricate the space between the outer ring 4 and the inner ring 5. The oil injection cylinder body 81 of the oil injection mechanism 8 is screwed into the first screw hole 6 and the second screw hole 7. After installing the oil injection mechanism 8, lubricating oil is injected into the oil injection cylinder body 81 from the oil injection port 82. Blocked by the sponge layer 84, the lubricating oil gradually passes through the gaps in the sponge layer 84 and falls on the first guide plate 86, then falls on the second guide plate 87 along the first guide plate 86, and then falls from the oil passage port 88 and enters the space between the outer ring 4 and the inner ring 5 along the oil injection cylinder body 81. The sponge layer 84 can slow down the flow rate of the lubricating oil by virtue of its internal structure. The upper surfaces of the first guide plate 86 and the second guide plate 87 are relatively gentle inclined planes, which can also slow down the flow rate of the lubricating oil. The inner diameters of the oil passage port 88 and the bottom of the oil injection cylinder body 81 are both small, which can reduce the flow rate of the lubricating oil, so that the lubricating oil enters the space between the outer ring 4 and the inner ring 5 at a slow flow rate and with a small flow rate. Only by regularly adding lubricating oil into the oil injection cylinder body 81 can the continuous lubrication of the spherical plain bearing be ensured, and the lubricating oil is not likely to seep out and no waste will be generated. By providing the buffer pad 2, when the spherical plain bearing is vibrated, the vibration is transmitted from the mounting seat 1 to the buffer pad 2, and the elasticity of the rubber material can weaken the vibration, thereby weakening the vibration received by the bearing seat 3.
