[0002] In the transmission systems of various mechanical equipment, the mating parts between rotating shafts and key components such as bearings and bushings are prone to wear failures due to long-term exposure to loads, high-speed relative motion, and friction. The lubrication status of these parts directly determines the operational stability, transmission efficiency, and service life of the equipment. Inadequate or untimely lubrication can easily lead to increased clearances, abnormal noises, overheating, and even jamming, potentially causing the entire transmission system to fail. Therefore, continuous, stable, and effective lubrication of the mating parts between rotating shafts and bearings / shoulders is a core element in ensuring the reliable operation of mechanical equipment. However, maintaining these lubrication points often presents challenges: Most equipment relies on manual, periodic replenishment of lubrication points using a grease gun. This method not only increases maintenance workload but is also highly susceptible to lubrication interruptions due to human negligence, forgetfulness, or improper replenishment, leading to serious malfunctions such as bearing dry friction and burnout. Therefore, an automatic lubrication replenishment structure for anti-wear shaft components is needed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic lubrication replenishment structure for anti-wear shaft components, including a bearing bracket 1, a bearing 101 installed inside the bearing bracket 1, a rotating shaft 102 installed in the middle of the bearing 101, a reciprocating thread groove 103 opened at the outer end of the rotating shaft 102 near the bearing 101, a ring plate 104 fixedly connected to the side end of the reciprocating thread groove 103 at the outer end of the rotating shaft 102, an oil storage component 3 for storing lubricating oil at the top of the bearing bracket 1, a switch component 4 for switching the oil storage component 3 to flow oil inside the oil storage component 3, a plurality of spring-loaded components 5 for automatically closing the oil storage component 3 at the side end of the switch component 4, and a pressing component 2 for pressing the switch component 4 to move and open. The bearing bracket 1 provides a stable mounting support for the bearing 101, ensuring stable operation of the bearing 101. The bearing 101 supports the rotating shaft 102 to achieve smooth rotation and reduce friction during the rotation of the rotating shaft 102. The reciprocating threaded groove 103 at the outer end of the rotating shaft 102 provides a transmission basis for the movement of the pressing component 2. The ring plate 104 can limit the travel of the pressing component 2 to prevent it from disengaging from the reciprocating threaded groove 103. The oil storage component 3 is responsible for storing lubricating oil to ensure the oil reserve for lubrication replenishment. The switch component 4 can control the opening and closing of the oil circuit of the oil storage component 3, and cooperate with the spring-loaded component 5 to realize the automatic closure of the oil circuit. The pressing component 2 can be driven by the rotation of the rotating shaft 102 to move, thereby pressing the switch component 4 to open the oil circuit. The whole system realizes automatic intermittent replenishment of lubricating oil without manual operation, which solves the problem of wear failure caused by easy interruption of manual replenishment.

[0023] As one implementation method in this embodiment, such as Figure 1As shown, the pressing component 2 includes a screw sleeve 201, which is threadedly connected to a reciprocating threaded groove 103. A connecting plate 202 is fixedly connected to the top end of the screw sleeve 201, and a pressing plate 203 is fixedly connected to the side end of the connecting plate 202. A limiting rod 105 is fixedly connected to the bottom side end of the bearing bracket 1. The limiting rod 105 is inserted into the bottom side end of the screw sleeve 201, and a limiting plate 106 is fixedly connected to the side end of the limiting rod 105. In practice, the screw sleeve 201 is threadedly engaged with the reciprocating threaded groove 103 of the rotating shaft 102. When the rotating shaft 102 rotates, under the limiting action of the limiting rod 105, the screw sleeve 201 will not rotate synchronously with the rotating shaft 102, but will move linearly back and forth along the reciprocating threaded groove 103. The connecting plate 202 fixes the screw sleeve 201 to the pressing plate 203, so that the pressing plate 203 moves synchronously when the screw sleeve 201 moves. The pressing plate 203 can press against the switch assembly 4 to make it move. The limiting rod 105 is inserted into the bottom of the screw sleeve 201 to play a guiding and limiting role, ensuring that the screw sleeve 201 moves smoothly. The limiting plate 106 can prevent the screw sleeve 201 from disengaging from the limiting rod 105, ensuring that the transmission of the pressing assembly 2 is stable and reliable.

[0024] As one implementation method in this embodiment, such as Figure 2 and Figure 4 As shown, the oil storage assembly 3 includes a mounting box 301, which is fixedly connected to the top of the bearing bracket 1. The mounting box 301 has a mounting groove 302 inside. An oil outlet hole 303 is provided between the top of the mounting groove 302, the top of the bearing bracket 1 and the inside of the bearing 101. An oil storage pipe 304 is fixedly connected to the top of the mounting box 301. A threaded cap 305 is threadedly connected to the top of the oil storage pipe 304. Two side plates 306 are fixedly connected to the outer side of the mounting box 301. In practice, the mounting box 301 is fixed to the top of the bearing bracket 1, providing installation space for the switch assembly 4. The mounting groove 302 is adapted to the installation and movement of the switch assembly 4. The oil outlet 303 enables the precise delivery of lubricating oil from the mounting box 301 to the inside of the bearing 101, ensuring that lubrication reaches the high-wear area directly. The oil storage pipe 304 is used to store sufficient lubricating oil to meet the continuous lubrication needs. The threaded cap 305 facilitates subsequent replenishment of lubricating oil and can also seal the oil storage pipe 304 to prevent lubricating oil leakage. The side plate 306 provides a stable installation support point for the spring-loaded assembly 5, ensuring the stable operation of the spring-loaded assembly 5.

[0025] As one implementation method in this embodiment, such as Figure 2 and Figure 4As shown, the switch assembly 4 includes an oil-blocking plate 401, which is inserted into the mounting groove 302. A force-bearing plate 402 is fixedly connected to the side end of the oil-blocking plate 401. A through groove 403 is provided between the top and bottom ends of the oil-blocking plate 401. The oil-blocking plate 401 extends to the outer end of the mounting box 301. A second side plate 404 is fixedly connected to the side end of the oil-blocking plate 401 located outside the mounting box 301. The rebound assembly 5 includes a round rod 501, which is fixedly connected to the side end of the second side plate 404. The round rod 501 is inserted into the side end of the first side plate 306. A round plate 502 is fixedly connected to the side end of the round rod 501. A spring 503 is sleeved on the outer end of the round rod 501. One end of the spring 503 is fixedly connected to the side end of the round plate 502, and the other end of the spring 503 is fixedly connected to the side end of the first side plate 306. During implementation, the oil-blocking plate 401 is inserted into the mounting groove 302 and can move freely. Under normal conditions, the through groove 403 is misaligned with the oil outlet 303 to achieve oil circuit sealing and leak prevention. The force plate 402 is used to bear the pressing force of the pressure component 2, which drives the oil-blocking plate 401 to move, so that the through groove 403 is aligned with the oil outlet 303, opening the oil circuit. The second side plate 404 provides a fixed carrier for the round rod 501 of the rebound component 5. The round rod 501 is inserted into the first side plate 306 and serves as a guide. The oil-blocking plate 401 is used to ensure smooth movement of the oil-blocking plate 401. The circular plate 502 prevents the circular rod 501 from detaching from the side plate 306. The spring 503 is sleeved on the outer end of the circular rod 501 and is normally in an extended state. When the oil-blocking plate 401 moves, the spring 503 is squeezed and contracted. After losing the pressing force, the spring 503 rebounds and drives the oil-blocking plate 401 to reset, so that the through groove 403 and the oil outlet 303 are misaligned and sealed again, realizing the automatic closure of the oil circuit, ensuring intermittent replenishment of lubricating oil, and avoiding oil waste.

[0026] Working principle: This device is suitable for transmission systems of various mechanical equipment. Its core solution is to address the problem of wear failure at the joint between the rotating shaft and the bearing caused by easy interruption of manual lubrication.

[0027] First, initial setup is performed. Bearing bracket 1 provides a stable mounting base for bearing 101. Bearing 101 supports shaft 102, maintaining its stability. Sufficient lubricating oil is pre-stored in the oil storage pipe 304 of oil storage assembly 3, and threaded cap 305 is tightened to seal and prevent leakage. The oil blocking plate 401 of switch assembly 4 is inserted into the mounting slot 302 of mounting box 301. Under normal conditions, the through slot 403 on oil blocking plate 401 is misaligned with the oil outlet 303 connecting mounting box 301 and bearing bracket 1, achieving oil circuit sealing and leak prevention. (Rebound assembly...) Spring 503 of 5 is in a naturally extended state. It provides stable support for oil-blocking plate 401 through the cooperation of round rod 501, side plate 306 and side plate 404. The screw sleeve 201 of the pressing component 2 is threadedly connected to the reciprocating thread groove 103 at the outer end of the rotating shaft 102. The limiting rod 105 at the bottom of the bearing bracket 1 is inserted into the bottom of the screw sleeve 201 to prevent the screw sleeve 201 from rotating with the rotating shaft 102. The ring plate 104 and the limiting plate 106 respectively limit the movement range of the screw sleeve 201 to prevent it from disengaging from the reciprocating thread groove 103 or the limiting rod 105.

[0028] Then, the rotating shaft 102 rotates to drive the pressing action. When the mechanical equipment runs and the rotating shaft 102 rotates at high speed, the threaded sleeve 201, which is threadedly connected to the reciprocating threaded groove 103, will not rotate synchronously with the rotating shaft 102 under the limiting action of the limiting rod 105. Instead, it will move linearly along the reciprocating threaded groove 103. When the threaded sleeve 201 moves, it drives the pressing plate 203 to move synchronously through the connecting plate 202 at the top. Then, the switch assembly 4 is linked to supply oil. When the pressing plate 203 moves to contact the force plate 402 of the switch assembly 4 and continues to press, the force plate 402 drives the oil blocking plate 401 to move along the mounting groove 302. The side plate 404 at the extended end of the oil blocking plate 401 simultaneously pulls the round rod 501 of the rebound assembly 5 to move. The spring 503 at the outer end of the round rod 501 is squeezed and contracted to generate elastic force. At this time, the through groove 403 on the oil blocking plate 401 moves with the oil blocking plate 401 to align with the oil outlet 303. The lubricating oil in the oil storage pipe 304 flows into the bearing 101 through the through groove 403 and the oil outlet 303 in sequence to lubricate the mating part of the rotating shaft 102 and the bearing 101 and avoid dry friction wear.

[0029] Finally, the springback reset interrupts the oil supply. When the sleeving 201 moves to the end along the reciprocating thread groove 103, it begins to move in the opposite direction under the guidance of the reciprocating thread. The pressing plate 203 moves in the opposite direction with the sleeving 201 and gradually disengages from the force plate 402. At this time, the spring 503 of the springback assembly 5 releases its elastic force, pushing the round rod 501 to reset the side plate 404 and the oil blocking plate 401. The through groove 403 of the oil blocking plate 401 is misaligned with the oil outlet 303 again, the oil circuit is resealed, and the lubricating oil supply is interrupted. As the rotating shaft 102 continues to rotate, the sleeving 201 moves back and forth along the reciprocating thread groove 103, driving the pressing plate 203 to cyclically press against and disengage from the force plate 402, causing the switch assembly 4 to cyclically open and close the oil circuit. This ultimately achieves intermittent automatic replenishment of lubricating oil to the bearing mating area, eliminating the need for regular manual operation, avoiding lubrication interruptions caused by human negligence, and ensuring the transmission stability and service life of the equipment.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
