However, when lubricating the shaft, it is difficult to ensure that the lubricant fully contacts the shaft, which can easily cause excessive friction in certain parts of the shaft during operation, leading to excessive wear, high temperatures, and damage to the shaft. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a matching device for bearing lubrication and hydraulic systems, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a cooperating device for bearing lubrication and hydraulic device, comprising: an electric motor, a base fixedly mounted on the bottom of the electric motor, a rotating shaft rotatably mounted inside the electric motor, and a lubrication device, a limiting device and a protective device provided on the circumferential surface of the rotating shaft; The lubrication device includes a fixed housing, a lubrication device, a lubrication pipe, a sealing door, and a spiral plate. The fixed housing is fixedly installed at the front of the motor, the lubrication device is fixedly installed at the bottom of the fixed housing, one end of the lubrication pipe is fixedly installed at the bottom of the fixed housing, and the other end of the lubrication pipe is fixedly installed at the bottom of the lubrication device. The sealing door is rotatably installed at the bottom of the lubrication device, and the spiral plate is fixedly installed on the circumference of the rotating shaft. When the motor drives the rotating shaft to rotate, the rotating shaft drives the spiral plate to start rotating. The rotation of the spiral plate causes the lubricating fluid inside the fixed housing to move. The lubricating fluid moves through the lubrication pipe into the lubrication device, and then the lubricating fluid enters the fixed housing again through the lubrication pipe.

[0007] According to the above technical solution, the lubrication device further includes a fixed plate, an electric telescopic rod, and a support block. The fixed plate is fixedly installed on the surface of the lubrication equipment, the electric telescopic rod is fixedly installed at the bottom of the fixed plate, and the support block is fixedly installed at the output end of the electric telescopic rod. When the lubricating fluid moves through the lubrication pipe into the lubrication equipment, the lubrication equipment starts the electric telescopic rod, causing the electric telescopic rod to push the support block to start moving downward, and the support block moves downward to make full contact with the support surface.

[0008] According to the above technical solution, the spiral plate is in contact with the fixed outer shell, and the lubrication device is electrically connected to the electric telescopic rod. The contact ensures that the spiral plate can drive the coolant to move, and the electrical connection ensures that the lubrication device can start the electric telescopic rod.

[0009] According to the above technical solution, the limiting device includes a pressure rod, a slide rail, two inclined blocks, and a limiting rod. The pressure rod is fixedly installed on the right side of the support block, the slide rail is fixedly installed on the surface of the lubrication equipment, the two inclined blocks are slidably installed on the top of the slide rail, and the limiting rod is fixedly installed on the bottom of the inclined blocks. When the support block moves downward, it drives the pressure rod to move downward. The pressure rod moves and contacts and pushes the inclined blocks to move along the slide rail. The movement of the inclined blocks drives the limiting rod to move. The limiting rod moves and contacts the closed door and restricts it.

[0010] According to the above technical solution, the limiting device further includes an elastic telescopic rod, a limiting block, a fixing block, and a button. The elastic telescopic rod is fixedly installed on the side of the inclined block near another inclined block. The limiting block is fixedly installed on the top of the movable end of the elastic telescopic rod. The fixing block is fixedly installed on the side of the lubrication device near the slide rail. The button is slidably installed inside the fixing block. As the inclined block moves along the slide rail, it drives the elastic telescopic rod to move. The movement of the elastic telescopic rod drives the limiting block to move. The limiting block moves and contacts the fixing block and begins to move downward under the action of the inclined surface. The limiting block moves downward and, under continuous movement, enters the limiting groove opened on the fixing block and limits the inclined block.

[0011] According to the above technical solution, the side of the pressure rod that contacts the inclined block is set as an inclined surface, the side of the limiting block that contacts the fixing block is set as an inclined surface, and the slide rail surface is provided with a sliding groove. By setting the inclined surface, it is ensured that the pressure rod can smoothly push the inclined block when moving, the inclined surface is ensured that the limiting block can be smoothly pushed when moving, and the sliding groove is provided to ensure that the limiting rod can move normally.

[0012] According to the above technical solution, a limiting groove is provided on the surface of the fixed block, and a spring is provided between the two inclined blocks. The limiting groove ensures that the limiting block is restricted, and the spring ensures that the inclined block can achieve self-reset.

[0013] According to the above technical solution, the protective device includes a connecting plate, a second elastic telescopic rod, a protective plate, a second inclined block, and a push rod. The connecting plate is fixedly installed at the bottom of the fixed housing. The second elastic telescopic rod is fixedly installed on the surface of the connecting plate. The protective plate is fixedly installed at the movable end of the second elastic telescopic rod. The second inclined block is fixedly installed on the side of the protective plate near the movable end of the second elastic telescopic rod. The push rod is fixedly installed at the bottom of the limiting rod. When the limiting rod starts to move, it drives the push rod to start to move. The push rod moves and contacts and pushes the second inclined block to start to move. The movement of the second inclined block drives the protective plate to start to move, and the protective plate moves outward.

[0014] According to the above technical solution, the protective device further includes an elastic telescopic rod three and a clamping plate. The elastic telescopic rod three is fixedly installed on the side of the guard plate near the inclined block two. The clamping plate is fixedly installed on the movable end of the elastic telescopic rod three. When the guard plate is impacted or squeezed during the outward extension of the guard plate, the guard plate moves towards the lubrication equipment and drives the elastic telescopic rod three to start moving. The movement of the elastic telescopic rod three drives the clamping plate to start moving. The clamping plate moves and contacts the lubrication pipe and fully clamps the lubrication pipe.

[0015] According to the above technical solution, the side of the push rod that contacts the inclined block 2 is set as an inclined surface, and the side of the clamping plate that contacts the lubrication pipe is set as an arc. By setting the inclined surface, it is ensured that the push rod can smoothly push the inclined block 2 when moving, and by setting the arc, it is ensured that the clamping plate can fully contact the lubrication pipe when moving.

[0016] This invention provides a matching device for bearing lubrication and hydraulic systems. It offers the following advantages: (1) The invention can increase the contact area between the lubricant and the shaft surface through the special structure of the spiral plate, thereby increasing the coverage of the lubricant film, which helps to reduce friction and wear, and thus extend the service life of the shaft. At the same time, the rotation or oblique design of the spiral plate can guide the lubricant to flow along a specific path, avoid the lubricant from stagnating in certain parts, ensure that the lubricant can be evenly distributed throughout the contact area, and effectively remove the heat generated on the shaft surface.

[0017] (2) The invention provides stable support for the lubrication device by moving the support block downward and making full contact with the support surface, ensuring that the lubrication system maintains a fixed position during operation, preventing the lubrication device from being displaced or damaged due to vibration or external force, which helps the lubrication system to operate stably for a long time. At the same time, it can effectively reduce the mechanical impact and vibration of the lubrication device and bearing system during operation, thereby reducing fatigue damage caused by long-term vibration and extending the service life of the bearing and lubrication system.

[0018] (3) The invention can effectively prevent the closed door of the lubrication equipment from opening accidentally during equipment operation by limiting the movement of the limiting rod to contact and restrict it. This avoids lubricant leakage or uneven lubrication caused by the sudden opening of the door, thereby reducing the risk of equipment failure or personal injury. At the same time, by preventing the door from opening accidentally, the possibility of lubrication system failure is reduced, thereby enhancing the long-term stability and reliability of the lubrication system.

[0019] (4) The invention restricts the inclined block by moving the limiting block downward and entering the limiting groove on the fixed block under continuous movement, thereby preventing the pressure rod from being damaged during operation and causing the inclined block to start moving and resetting under the action of the spring, so that the closed door is no longer restricted and the lubrication device is stably operated during operation.

[0020] (5) The invention can effectively prevent damage to the lubrication device caused by external objects or impacts and friction generated during operation by moving the guard plate outward, avoid other substances from contaminating or clogging the lubrication device, bearings and other components, ensure the stability of the lubrication effect, and effectively protect the lubrication device from contamination, reduce the cleaning frequency and maintenance difficulty of the equipment surface and components.

[0021] (6) The invention, by moving the clamping plate to contact the lubrication pipe and fully clamping the lubrication pipe, ensures that the lubrication pipe will not break or loosen when the guard plate is hit or squeezed, thereby ensuring the normal operation of the lubrication system. At the same time, it can effectively enhance the connection strength between the lubrication pipe and other components. Especially in the case of external impact or vibration, it can prevent the lubrication pipe from twisting or detaching due to excessive pressure, and maintain the stability of the overall device.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8 One embodiment of the present invention is: a bearing lubrication and hydraulic device, comprising: an electric motor 1, a base 2 fixedly mounted on the bottom of the electric motor 1, a rotating shaft 3 rotatably mounted inside the electric motor 1, and a lubrication device provided on the circumferential surface of the rotating shaft 3; The lubrication device includes a fixed housing 4, a lubrication device 5, a lubrication pipe 6, a sealing door 7, and a spiral plate 8. The fixed housing 4 is fixedly installed at the front of the motor 1, the lubrication device 5 is fixedly installed at the bottom of the fixed housing 4, one end of the lubrication pipe 6 is fixedly installed at the bottom of the fixed housing 4, and the other end of the lubrication pipe 6 is fixedly installed at the bottom of the lubrication device 5. The sealing door 7 is rotatably installed at the bottom of the lubrication device 5, and the spiral plate 8 is fixedly installed on the circumferential surface of the rotating shaft 3. Through the special structure of the spiral plate 8, the contact area between the lubricant and the surface of the rotating shaft 3 can be increased, thereby improving the coverage of the lubricant film, helping to reduce friction and wear, and thus extending the service life of the rotating shaft 3. At the same time, the rotation or oblique design of the spiral plate 8 can guide the lubricant to flow along a specific path, avoiding the lubricant from stagnating in certain parts, ensuring that the lubricant can be evenly distributed throughout the contact area, and effectively carrying away the heat generated on the surface of the rotating shaft 3.

[0026] The lubrication device also includes a fixed plate 9, an electric telescopic rod 10, and a support block 11. The fixed plate 9 is fixedly installed on the surface of the lubrication equipment 5, the electric telescopic rod 10 is fixedly installed at the bottom of the fixed plate 9, and the support block 11 is fixedly installed at the output end of the electric telescopic rod 10. The support block 11 moves downward and makes full contact with the support surface, providing stable support for the lubrication device, ensuring that the lubrication system maintains a fixed position during operation, preventing the lubrication device from being displaced or damaged due to vibration or external forces, and contributing to the long-term stable operation of the lubrication system. At the same time, it can effectively reduce the mechanical shock and vibration of the lubrication device and bearing system during operation, thereby reducing fatigue damage caused by long-term vibration and extending the service life of the bearing and lubrication system.

[0027] The spiral plate 8 contacts the fixed housing 4, and the lubrication device 5 is electrically connected to the electric telescopic rod 10. The contact ensures that the spiral plate 8 can drive the lubricant to move, and the electrical connection ensures that the lubrication device 5 can start the electric telescopic rod 10.

[0028] When this embodiment is working: Before the servo motor starts working, professional personnel place it in the designated working area and then inspect the entire servo motor assembly. After confirming everything is in order, the personnel start the motor 1, causing it to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the components to start working. Simultaneously, the rotating shaft 3 drives the spiral plate 8 to rotate. The rotation of the spiral plate 8 moves the lubricating fluid inside the fixed housing 4. The lubricating fluid then enters the lubrication device 5 through the lubrication pipe 6, and subsequently re-enters the fixed housing 4 through the lubrication pipe 6. The special structure of the spiral plate 8 increases the contact area between the lubricating fluid and the surface of the rotating shaft 3, thereby improving the coverage of the lubricating fluid film, helping to reduce friction and wear, and extending the service life of the rotating shaft 3. Furthermore, the rotational or oblique design of the spiral plate 8 can... The lubricant is guided to flow along a specific path, preventing it from stagnating in certain areas and ensuring its even distribution throughout the contact area. It effectively removes heat generated on the surface of the rotating shaft 3. Simultaneously, as the lubricant moves through the lubrication pipe 6 into the lubrication device 5, the device activates the electric telescopic rod 10, which pushes the support block 11 downwards. The support block 11 moves downwards and makes full contact with the support surface, providing stable support for the lubrication device. This ensures the lubrication system remains in a fixed position during operation, preventing displacement or damage due to vibration or external forces. This contributes to the long-term stable operation of the lubrication system and effectively reduces mechanical shock and vibration during operation of the lubrication device and bearing system, thereby reducing fatigue damage caused by long-term vibration and extending the service life of the bearings and lubrication system.

[0029] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a limiting device and a protective device are provided on the circumferential surface of the rotating shaft 3.

[0030] The limiting device includes a pressure rod 121, a slide rail 122, two inclined blocks 123, and a limiting rod 124. The pressure rod 121 is fixedly installed on the right side of the support block 11, the slide rail 122 is fixedly installed on the surface of the lubrication equipment 5, the two inclined blocks 123 are slidably installed on the top of the slide rail 122, and the limiting rod 124 is fixedly installed on the bottom of the inclined blocks 123. By moving the limiting rod 124 to contact and restrict the closed door 7, the closed door 7 of the lubrication equipment 5 can be effectively prevented from opening accidentally during equipment operation. This avoids lubricant leakage or uneven lubrication caused by the sudden opening of the door, thereby reducing the risk of equipment failure or personal injury. At the same time, by preventing the door from opening accidentally, the possibility of lubrication system failure is reduced, thereby enhancing the long-term stability and reliability of the lubrication system.

[0031] The limiting device also includes an elastic telescopic rod 125, a limiting block 126, a fixing block 127, and a button 128. The elastic telescopic rod 125 is fixedly installed on the side of the inclined block 123 near another inclined block 123. The limiting block 126 is fixedly installed on the top of the movable end of the elastic telescopic rod 125. The fixing block 127 is fixedly installed on the side of the lubrication device 5 near the slide rail 122. The button 128 is slidably installed inside the fixing block 127. By moving downward through the limiting block 126 and continuously moving, it enters the limiting groove opened on the fixing block 127 and limits the inclined block 123. This prevents damage to the pressure rod 121 during operation, which would cause the inclined block 123 to start moving and resetting under the action of the spring, so that the closed door 7 is no longer restricted, ensuring the stable operation of the lubrication device during operation.

[0032] The sides of the pressure rod 121 that contact the inclined block 123 are both set as inclined surfaces, the side of the limiting block 126 that contacts the fixing block 127 is set as an inclined surface, and the slide rail 122 has a groove on its surface. By setting the inclined surfaces, it is ensured that the pressure rod 121 can smoothly push the inclined block 123 when it moves, and the limiting block 126 can be smoothly pushed when it moves. By setting the groove, it is ensured that the limiting rod 124 can move normally.

[0033] A limiting groove is provided on the surface of the fixed block 127, and a spring is provided between the two inclined blocks 123. The limiting groove ensures that the limiting block 126 is restricted, and the spring ensures that the inclined block 123 can achieve self-reset.

[0034] The protective device includes a connecting plate 131, a second elastic telescopic rod 132, a guard plate 133, a second inclined block 134, and a push rod 135. The connecting plate 131 is fixedly installed at the bottom of the fixed housing 4. The second elastic telescopic rod 132 is fixedly installed on the surface of the connecting plate 131. The guard plate 133 is fixedly installed at the movable end of the second elastic telescopic rod 132. The second inclined block 134 is fixedly installed on the side of the guard plate 133 near the movable end of the second elastic telescopic rod 132. The push rod 135 is fixedly installed at the bottom of the limiting rod 124 and extends outward through the movement of the guard plate 133. It can effectively prevent damage to the lubrication device from external objects or impacts and friction generated during operation, avoid other substances from contaminating or clogging the lubrication device, bearings, and other components, ensure the stability of the lubrication effect, and effectively protect the lubrication device from contamination, reducing the frequency of cleaning and maintenance of equipment surfaces and components.

[0035] The protective device also includes a flexible telescopic rod 136 and a clamping plate 137. The flexible telescopic rod 136 is fixedly installed on the side of the guard plate 133 near the inclined block 134. The clamping plate 137 is fixedly installed on the movable end of the flexible telescopic rod 136. The clamping plate 137 moves to contact the lubrication pipe 6 and fully clamps the lubrication pipe 6, ensuring that the lubrication pipe 6 will not break or loosen when the guard plate 133 is impacted or squeezed, thereby ensuring the normal operation of the lubrication system. At the same time, it can effectively enhance the connection strength between the lubrication pipe 6 and other components. Especially under external impact or vibration, it can prevent the lubrication pipe 6 from twisting or detaching due to excessive pressure, maintaining the stability of the overall device.

[0036] The surfaces of the push rod 135 and the inclined block 134 that come into contact with each other are both set as inclined surfaces, while the surface of the clamping plate 137 that comes into contact with the lubrication pipe 6 is set as an arc. The inclined surfaces ensure that the push rod 135 can smoothly push the inclined block 134 when moving, and the arc shape ensures that the clamping plate 137 can make full contact with the lubrication pipe 6 when moving. When this embodiment is working: As the support block 11 moves downward, it drives the pressure rod 121 to move downward as well. The pressure rod 121 moves and contacts the inclined block 123, which then moves along the slide rail 122. The movement of the inclined block 123 drives the limiting rod 124 to move, which then contacts and restricts the closed door 7. This effectively prevents the closed door 7 of the lubrication equipment 5 from opening accidentally during operation, thus avoiding lubricant leakage or uneven lubrication caused by sudden door opening. This reduces the risk of equipment failure or personal injury. At the same time, by preventing accidental door opening, the possibility of lubrication system failure is reduced, thereby enhancing the long-term stability and reliability of the lubrication system. As the inclined block 123 moves along the slide rail 122, it also drives the elastic telescopic rod 125 to move. The movement of the elastic telescopic rod 125 causes the limiting block 126 to move. The limiting block 126 moves and contacts the fixed block 127 and begins to move downward under the action of the inclined plane. The limiting block 126 moves downward and enters the limiting groove on the fixed block 127 under continuous movement, thus limiting the inclined block 123. This prevents the pressure rod 121 from being damaged during operation, causing the inclined block 123 to move and reset under the action of the spring, so that the closed door 7 is no longer restricted. This ensures the stable operation of the lubrication device during operation. When it is necessary to release the restriction at the end of the operation, the operator manually presses the button 128, which pushes the limiting block 126 to move downward. The limiting block 126 moves and disengages from the limiting groove on the fixed block 127, thus releasing the restriction on the inclined block 123.

[0037] As the limiting rod 124 begins to move, it drives the push rod 135 to move as well. The push rod 135 moves and contacts and pushes the inclined block 134 to move. The movement of the inclined block 134 drives the guard plate 133 to move. The guard plate 133 extends outward, effectively preventing damage to the lubrication device from external objects or impacts and friction generated during operation. It also prevents other substances from contaminating or clogging the lubrication device, bearings, and other components, ensuring the stability of the lubrication effect. At the same time, it effectively protects the lubrication device from contamination, reducing the frequency of cleaning and maintenance of equipment surfaces and components. During the outward extension of the guard plate 133, the guard plate 133 is subjected to... Upon impact or compression, the guard plate 133 moves toward the lubrication device 5 and drives the elastic telescopic rod 136 to move. The movement of the elastic telescopic rod 136 drives the clamping plate 137 to move. The clamping plate 137 moves to contact the lubrication pipe 6 and fully clamps the lubrication pipe 6, ensuring that the lubrication pipe 6 will not break or loosen when the guard plate 133 is impacted or compressed, thereby ensuring the normal operation of the lubrication system. At the same time, it can effectively enhance the connection strength between the lubrication pipe 6 and other components. Especially under external impact or vibration, it can prevent the lubrication pipe 6 from twisting or detaching due to excessive pressure, maintaining the stability of the overall device.
