Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a lubrication device for bearings. Background Technology

[0002] Bearings are key mechanical components that provide support and reduce friction during mechanical transmission. A bearing mainly consists of an inner ring, an outer ring, rolling elements, and a cage. The inner ring rotates in close contact with the shaft, while the outer ring is fixed to the equipment and remains stationary. The rolling elements roll in the raceways to reduce friction, while the cage maintains the spacing between the rolling elements, prevents collisions, guides their proper rolling, and ensures smooth bearing operation. Bearings are widely used in numerous fields, playing a vital role in support and friction reduction.

[0003] A bearing lubrication device is a specialized device designed to provide lubricating media to bearings, ensuring their proper operation under optimal lubrication conditions. Its core function is to ensure a sufficient and continuous supply of lubricating media between the relatively moving contact surfaces during bearing operation. This lubrication effectively reduces the coefficient of friction between contact surfaces, minimizes wear, prevents overheating damage caused by excessive frictional heat, and also provides rust prevention and vibration damping. However, in existing bearing lubrication devices, manually added lubricant has poor flowability, making it difficult to distribute evenly and quickly to all contact surfaces requiring lubrication in complex bearing structures and areas requiring precise lubrication. This can easily lead to insufficient localized lubrication, affecting the overall lubrication effect of the bearing. Utility Model Content

[0032] Specifically, the device uses a fixed shell 1 as a base, with a rotating shaft 3 supporting a cover plate 4 for opening and closing. When the motor 5 is working, it transmits rotational power to the hydraulic rod 7 through an adjusting rod 6, changing its angle and position. The hydraulic rod 7 swings and the working medium is transmitted through a conduit 8. A connecting pipe 9 ensures the connectivity of the hydraulic system. The rotation of the adjusting rod 6 is stabilized by a support frame 10, and the movement of the hydraulic rod 7 is guided by a rotating ring 11 and a connecting rod 12, achieving stable and orderly swinging and extension. The rotating ring 11 and the connecting rod 12 work together to control the movement trajectory of the hydraulic rod 7, precisely adjusting its position and adding lubricating oil to meet the lubrication requirements of complex bearing structures and improve the overall lubrication effect. A clamping mechanism 2 is fixedly connected to the middle of the inner wall of the fixed shell 1. The clamping mechanism 2 is used to clamp and fix the bearing. Threaded rods 13 are fixedly connected to the four corners at the bottom of the fixed shell 1. The threaded rods 13 are not only firmly fixed to the shell to facilitate precise adjustment of the foot pads 14, but each threaded rod 13 is also connected to the foot pads 14, ensuring the stability and durability of the entire structure.

[0033] Reference Figure 1 , Figure 2 and Figure 5The clamping mechanism 2 includes a spring 201, which is fixedly connected to the middle of the inner wall of the fixed shell 1. A fixed plate 202 is fixedly connected to the top of the outer wall of the spring 201. Multiple support plates 203 are fixedly connected to the middle of the inner wall of the fixed shell 1. A clamping plate 204 is rotatably connected to the top of the outer wall of the multiple support plates 203. A spring 205 is fixedly connected to the side of the outer wall of the clamping plate 204 away from the front. A pressing plate 206 is fixedly connected to the front side of the outer wall of the front clamping plate 204. A fixing ring 207 is fixedly connected to the middle of the inner wall of the multiple clamping plates 204. The other end of the connecting pipe 9 is connected to the feed hopper 15.

[0034] Specifically, one end of spring 201 is fixed to the inner wall of the fixed shell 1, and the other end is connected to the fixed plate 202. In the initial state, the spring is extended, applying elastic force to the fixed plate 202 and maintaining its initial position. Under the action of external force, the spring is compressed to store energy, and the fixed plate 202 moves in the direction of the external force; after the external force is removed, the restoring force of the spring causes the fixed plate 202 to return to its original position. Multiple support plates 203 are connected to the inner wall of the fixed shell 1. The support plates 203 are rotatably connected to the clamping plate 204, and the clamping plate 204 can be opened and closed by changing its angle. A second spring 205 is connected to the outer side of the clamping plate 204 to keep the clamping plate 204 in an open state. When an external force causes the clamping plate 204 to approach, the second spring 205 stretches and stores energy. After the external force disappears, the restoring force of the second spring 205 causes the clamping plate 204 to return to its original open state. A pressing plate 206 is fixed to the outer side of the front clamping plate 204 to facilitate the operator to apply force. The pressing plate 206 makes the clamping plate 204 overcome the elastic force of the second spring 205 for clamping. A fixing ring 207 is fixed in the middle of the inner wall of the clamping plate 204 for positioning and fixing the installation parts. The other end of the connecting pipe 9 is connected to a feeding hopper 15 to facilitate the user to add lubricant and increase the convenience of operation. A dust cover 16 is rotatably connected to the top of the outer wall of the feeding hopper 15 to prevent dust from entering. A wear-resistant sleeve 17 is installed on the front side of the outer wall of the pressing plate 206. The top of the outer wall of this wear-resistant sleeve 17 has anti-slip texture 18 to increase friction and prevent slippage during operation.

[0035] Reference Figure 1 , Figure 2 and Figure 3 An operating table 19 is fixedly connected to the top of the outer wall of the cover plate 4. A display screen 20 is provided on the top of the outer wall of the operating table 19. A fixing frame 21 is fixedly connected to the top of the inner wall of the cover plate 4. Bolts 22 are threadedly connected to the four corners at the bottom of the fixing frame 21. A handle 23 is fixedly connected to the front side of the outer wall of the cover plate 4. Anti-slip texture 24 is provided on the top of the outer wall of the handle 23.

[0036] Specifically, an operating table 19 is fixedly connected to the top of the outer wall of the cover plate 4 for user operation and control. A display screen 20 is provided on the top of the outer wall of the operating table 19 so that users can view relevant information. A fixing bracket 21 is fixedly connected to the top of the inner wall of the cover plate 4. Bolts 22 are threadedly connected to the four corners of the bottom of the fixing bracket 21 to ensure the stability of the motor 5. In addition, a handle 23 is fixedly connected to the front of the outer wall of the cover plate 4 to facilitate the user to close the cover plate 4 and improve work efficiency. The top of the outer wall of the handle 23 is specially designed with anti-slip texture 24 to provide a better grip and ensure the safety of the user during use.

[0037] Working Principle: The entire device uses a fixed shell 1 as its basic structure. A rotating shaft 3 on the rear side of its outer wall supports a cover plate 4, allowing the cover plate 4 to rotate around the shaft 3, thus opening and closing. When the motor 5 is powered on, it transmits its rotational power to the fixedly connected adjusting rod 6, causing the adjusting rod 6 to rotate. The rotation of the adjusting rod 6 drives the connected hydraulic rod 7. Due to the rotating connection, the rotation of the adjusting rod 6 changes the relative angle and position of the hydraulic rod 7, causing it to swing within a certain range. The swing amplitude and direction are circular. The conduit 8 at the bottom of the hydraulic rod 7 is part of the hydraulic system, used to transmit the hydraulic working medium. The connecting pipe 9 ensures the continuity of the hydraulic rod 7. When the hydraulic rod 7 changes its angle under the influence of the adjusting rod 6, the hydraulic system adjusts its position according to internal pressure changes and hydraulic oil flow. The hydraulic rod 7 supplies lubricating oil, and the support frame 10 through which the adjusting rod 6 passes plays a role in stabilizing and supporting the adjusting rod 6. The rotating ring 11, which is rotatably connected to the front and rear sides of its inner wall, can rotate around the corresponding position. The rotating ring 11 is connected to the left and right sides of the outer wall of the hydraulic rod 7 through the connecting rod 12. During the rotation of the adjusting rod 6, it will drive the rotating ring 11 to rotate. The rotation of the rotating ring 11 will further constrain and guide the movement of the hydraulic rod 7 through the connecting rod 12, making the swing and extension movements of the hydraulic rod 7 more stable and orderly. At the same time, according to the linkage relationship between the rotating ring 11 and the connecting rod 12, the movement trajectory of the hydraulic rod 7 can be precisely controlled to achieve more accurate position adjustment and lubrication, realize automated lubrication, and deal with some complex bearing structures and fine lubrication parts. It can evenly and quickly distribute the lubricant to all contact surfaces that need lubrication, meet the situation of local lubrication, and improve the overall lubrication effect of the bearing.

[0038] One end of spring 201 is fixedly connected to the middle of the inner wall of the fixed shell 1, and the other end is fixedly connected to the fixed plate 202. In the initial state, spring 201 is in a certain naturally extended state. The bearing applies a certain elastic force to the fixed plate 202, so that the fixed plate 202 is maintained in the corresponding initial position. When an external force is applied to the fixed plate 202, the bearing applies a downward force, and spring 201 will be compressed accordingly according to the magnitude of the external force, storing elastic potential energy. At the same time, the fixed plate 202 will move downward along the direction of the external force. When the external force is removed, spring 201 will... The elastic restoring force of the plate itself will push the fixing plate 202 back to its original position, thereby fixing and compressing the fixing plate 202 in the vertical direction. Multiple support plates 203 are fixedly connected to the middle of the inner wall of the fixing shell 1. These support plates 203 serve to support and position the plate. The top of their outer walls is rotatably connected to the clamping plate 204, allowing the clamping plate 204 to rotate about the support plates 203 and their connection points, changing its angle and thus achieving opening and closing actions. This provides power to the subsequent clamping bearings. A second spring 205 is fixedly connected to the opposite side. The elastic force of the second spring 205 keeps the clamping plates 204 in a relatively open state, with gaps between adjacent clamping plates 204. When an external force pushes the clamping plates 204 to rotate inward, bringing them closer together, the second spring 205 is stretched, storing elastic potential energy. Once the external force disappears, the second spring 205, relying on its own elastic restoring force, pulls the clamping plates 204 back to their original relatively open position, restoring their initial state and achieving convenient free adjustment. The outer wall of the front clamping plate 204 is fixed at the front side. A pressing plate 206 is fixedly connected, providing an easy point for the operator to apply force. When the clamping plate 204 needs to perform a clamping action, the operator can press the pressing plate 206 to transfer external force to the clamping plate 204 connected to it, so that the clamping plate 204 overcomes the elastic force of the spring 205 and rotates inward around the connection point of the support plate 203, thereby clamping the object placed between them. A fixing ring 207 is fixedly connected to the middle of the inner wall of the multiple clamping plates 204, which serves to position and fix the installation components.
