Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically to a one-way clutch. Background Technology

[0002] One-way clutches are widely used components in the field of mechanical transmission, enabling the one-way transmission of power. They play a key role in many devices. With the advancement of the industrial revolution, various mechanical equipment are developing towards higher speeds and larger torques, making the demand for one-way clutch functions more urgent. Traditional methods are no longer sufficient to meet this demand. In the face of complex and ever-changing working conditions, and with the rapid development of new energy vehicles, one-way clutches are also constantly evolving to meet the changing market demands.

[0003] For example, CN221443145U discloses a one-way clutch, including a shaft body and a clutch gear. The clutch gear includes a gear body and a bearing support. The bearing support is sleeved with the gear body to form a plurality of track grooves evenly distributed in a ring array. The track grooves are arc-shaped, and needle rollers and elastic devices are installed in the track grooves. The elastic devices are disposed between the track grooves and the corresponding needle rollers. The shaft body is sleeved with the bearing support, and each needle roller abuts against the shaft body. This one-way clutch of the present invention makes the disassembly and assembly of the clutch gear more convenient, reduces the processing difficulty, improves the yield of the one-way clutch, and makes the clutch operation more reliable and smooth.

[0004] However, in traditional mechanical transmission systems, unidirectional motion is relatively simple to achieve, often relying on gravity or simple friction. This results in poor stability, susceptibility to fluctuations in operating conditions, insufficient precision, difficulty in adapting to precision transmission requirements, and limited load-bearing capacity, making it difficult to cope with medium- to high-load scenarios. More importantly, under long-term high-speed operation, the wear of core components will continue to accelerate, which can easily cause equipment jamming, interrupt continuous operation, and may even directly lead to component failure, shortening equipment lifespan and significantly increasing maintenance costs and downtime risks. Therefore, those skilled in the art provide a unidirectional clutch to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a one-way clutch that solves the problem of excessive friction in traditional one-way clutches, which leads to poor equipment stability.

[0006] This utility model provides the following technical solution: a one-way clutch, including a lubrication mechanism for transmitting power to a main component, wherein the outer wall of the lubrication mechanism is provided with a main component for bearing and positioning, and the inner wall of the lubrication mechanism is fixedly installed with a switching mechanism for closing the lubrication channel.

[0007] As a preferred embodiment of the above technical solution, the main body mechanism has an inner ring and an outer ring. The inner wall of the inner ring has an inner groove. A spring and a roller are provided in the inner groove. One end of the spring abuts against the side wall of the inner groove, and the other end abuts against the roller. The roller can rotate in the inner groove.

[0008] As a preferred embodiment of the above technical solution, the lubrication mechanism includes a rotating shaft with an insertion hole inside. The insertion hole has two slots. A sealing cover is slidably connected to the inner wall of the rotating shaft. Fixing blocks are fixedly connected to both sides of the outer wall of the sealing cover. Two elastic buckles are fixedly connected to the outer wall of the fixing blocks, and the elastic buckles engage with the slots.

[0009] As a preferred embodiment of the above technical solution, the rotating shaft has several guide grooves inside, and solid lubricating oil is installed inside the rotating shaft. The guide grooves are fitted to the inner wall of the inner ring.

[0010] As a preferred embodiment of the above technical solution, the rotating shaft has several pinholes inside, and the pinholes penetrate the slot.

[0011] As a preferred embodiment of the above technical solution, one end of the inner groove has a small opening and the other end of the inner groove has a large opening.

[0012] As a preferred embodiment of the above technical solution, the solid lubricating oil material is bentonite-thickened grease.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model is equipped with a lubrication mechanism. The rotating shaft is the core for stable power transmission. The elastic buckle of the sealing cover engages with the groove to tightly seal the lubrication channel and prevent the internal lubricant from leaking out. During maintenance, the buckle can be pressed to disassemble the device, which balances sealing performance and convenience. The guide groove inside the rotating shaft fits against the inner wall of the inner ring, which can accurately deliver the lubricating components released by the solid lubricating oil when heated to the friction point between the inner ring and the roller, reducing wear and avoiding lubrication waste, and ensuring the long-term stable operation of the main mechanism.

[0014] Based on the aforementioned beneficial effects, this utility model features a main structure that achieves unidirectional locking and transmission through the mechanical cooperation of a rotating shaft, rollers, and springs. This eliminates the need for complex electrical control components, reducing the risk of malfunctions and manufacturing costs. Furthermore, this structure offers high power transmission efficiency. When the rotating shaft rotates forward, it pushes the rollers towards the large groove, ensuring that the rotating shaft cannot drive the main structure to rotate. When the rotating shaft rotates in the reverse direction, the rollers quickly lock the rotating shaft and the main structure together, providing rapid response and strong component adaptability. The inner groove provides stable installation space for the rollers and springs, and the springs can adaptively adjust the roller position to compensate for minor assembly errors, effectively improving overall operational stability and service life.

[0017] 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.

[0018] Please see Figures 1-5 As shown, this utility model provides a technical solution: a one-way clutch, including a lubrication mechanism 1 for transmitting power to the main body assembly, a main body mechanism 2 for bearing and positioning provided on the outer wall of the lubrication mechanism 1, and a switching mechanism 3 for closing the lubrication channel fixedly installed on the inner wall of the lubrication mechanism 1.

[0019] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the main body mechanism 2 has an inner ring 21 and an outer ring 25. An inner groove 22 is formed on the inner wall of the inner ring 21. A spring 23 and a roller 24 are disposed within the inner groove 22. One end of the spring 23 abuts against the side wall of the inner groove 22, and the other end abuts against the roller 24. The roller 24 can slide and rotate within the inner groove 22 and can abut against the outer wall of the lubrication mechanism 1. In this embodiment, three inner grooves 22 are spaced apart, and each inner groove 22 contains a spring 23 and a roller 24.

[0020] As one implementation method in this embodiment, please refer to Figure 4 As shown, one end of the inner groove 22 is a small opening, and the other end of the inner groove 22 is a large opening. The small opening and the large opening of the inner groove 22 form a wedge-shaped space.

[0021] As one implementation method in this embodiment, please refer to Figures 2-5As shown, the lubrication mechanism 1 includes a rotating shaft 11, with an insertion hole 15 inside the rotating shaft 11. Two slots 14 are provided inside the insertion hole 15. A sealing cover 31 is slidably connected to the inner wall of the rotating shaft 11. Fixing blocks 32 are fixedly connected to both sides of the outer wall of the sealing cover 31. Two elastic buckles 33 are fixedly connected to the outer wall of the fixing blocks 32. The elastic buckles 33 engage with the slots 14.

[0022] The lubrication mechanism 1 uses the rotating shaft 11 as its core to transmit power. During operation, external power is input through the rotating shaft 11, driving the one-way clutch to rotate. At the same time, the rotating shaft 11 cooperates with the sealing cover 31 of the switching mechanism 3 through the internal insertion hole 15 to achieve the sealing and protection of the lubrication channel. During assembly, the sealing cover 31 is pushed into the inner wall of the rotating shaft 11, and the elastic buckle 33 on its outer wall is compressed and contracted. After the sealing cover 31 is fully in place, the elastic buckle 33 pops open and precisely engages with the slot 14 in the insertion hole 15 to fix the sealing cover 31. During this process, the sealing cover 31 fits tightly against the inner wall of the rotating shaft 11, blocking the lubrication channel from communicating with the outside world and preventing the internal lubricant from leaking out. When maintenance is required, press the elastic buckle 33 to disengage it from the slot 14, and the sealing cover 31 can be removed. This ensures smooth transmission and facilitates subsequent maintenance.

[0023] As one implementation method in this embodiment, please refer to Figure 3 and Figure 5 As shown, the shaft 11 has several guide grooves 13 inside, and solid lubricating oil 16 is installed inside the shaft 11. The guide grooves 13 fit the inner wall of the inner ring 21.

[0024] When the clutch is in operation, the solid lubricating oil 16 in the rotating shaft 11 slowly releases lubricating components with the heat generated by the rotation of the rotating shaft 11. These components flow in a direction through several guide grooves 13. Because the guide grooves 13 are in contact with the inner wall of the inner ring 21, the lubricating material can be accurately delivered to the contact area between the inner ring 21 and the roller 24, ensuring that the lubricating material evenly covers the friction surface, reducing wear when the inner ring 21 and the roller 24 move relative to each other, while avoiding waste of lubricating material and ensuring the long-term stable operation of the main mechanism 2.

[0025] As one implementation method in this embodiment, please refer to Figure 5 As shown, the rotating shaft 11 has several pinholes 12 inside, and the pinholes 12 pass through the slot 14.

[0026] The pinhole 12 penetrates the slot 14 and mainly serves as an auxiliary tool for opening the cover. When opening the sealing cover 31, a tool is inserted through the pinhole 12 to help the elastic buckle 33 compress and disengage from the slot 14, thus completing the opening action. Lubricant can be added. If there is misalignment during assembly, a thin rod can also be inserted through the pinhole 12 to push the elastic buckle 33 back to its original position and engage precisely, preventing the buckle from being misaligned and causing the sealing cover 31 to loosen. At the same time, the pinhole 12 can balance the internal air pressure of the rotating shaft 11, preventing temperature changes from affecting the sealing performance of the sealing cover 31 due to the internal and external pressure difference, and ensuring the stability of the overall structure.

[0027] Solid lubricating oil 16 is composed of bentonite-thickened grease.

[0028] Solid lubricating oil 16 uses bentonite-thickened grease. When the clutch is running, the rotating shaft 11 heats up, causing the grease to slowly release lubricating components. These components flow through the guide groove 13 to the contact point between the inner ring 21 and the roller 24. The bentonite thickener ensures that the grease does not melt or run off at high temperatures, continuously forming an oil film to reduce friction and ensure stable and smooth one-way clutch operation.

[0029] Working principle: During the operation of the one-way clutch, the main body mechanism 2, as the core locking and transmission component, dynamically switches its working state according to the direction of power transmission. by Figure 2 Taking the state shown as an example, when the rotating shaft 11 rotates in the forward direction (rotating shaft 11 rotates clockwise), the outer wall of the rotating shaft 11 will push the roller 24 towards the large slot, and the spring 23 will be compressed. At this time, the roller 24 cannot be located in the small slot and lock the outer wall of the rotating shaft 11. The rotating shaft 11 cannot lock with the main body mechanism 2. The rotating shaft 11 can only rotate freely in the inner ring 21 and cannot transmit power to the main body mechanism 2.

[0030] When the shaft 11 rotates in the reverse direction, the spring 23 naturally relaxes, pushing the rollers 24 towards the small groove, causing each roller 24 to lock against the outer wall of the shaft 11. At this time, the shaft 11 and the main body mechanism 2 are locked together, and the shaft 11 can drive the main body mechanism 2, rollers 24, and spring 23 to rotate as a whole. That is, the shaft 11 can only drive the main body mechanism 2 to rotate together when rotating in the reverse direction, thereby realizing unidirectional power transmission.

[0031] In the lubrication mechanism 1, the solid lubricating oil 16 in the rotating shaft 11 releases lubricating components with the heat of operation and is accurately delivered to the friction point between the inner ring 21 and the roller 24 through the guide groove 13. The sealing cover 31 of the switching mechanism 3 is engaged with the slot 14 through the elastic buckle 33 to seal the lubrication channel in the insertion hole 15. The pinhole 12 assists in the disassembly and assembly of the buckle and the observation of its status, which not only prevents the loss of grease but also facilitates maintenance and ensures stable operation of the whole.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
