Description

Technical Field

[0001] This utility model belongs to the field of mechanical transmission technology, specifically a self-lubricating transmission gear. Background Technology

[0002] In mechanical transmission systems, gear transmission is one of the most common forms. During the meshing process, gears generate friction and wear, which not only reduces transmission efficiency but also shortens the service life of the gears. To reduce friction and wear, traditional gear transmission systems require manual lubrication at regular intervals. However, this method has many drawbacks, such as wasting manpower and uneven lubrication. Therefore, it is particularly important to develop a transmission gear with self-lubricating function. Utility Model Content

[0003] To address the problems existing in the background art, this utility model provides a self-lubricating transmission gear.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a self-lubricating transmission gear, comprising a gear body, an oil storage cavity, an oil outlet, multiple pressing mechanisms, and multiple restoring mechanisms;

[0005] The gear body is provided with an oil storage cavity. There is an oil outlet hole between every two adjacent teeth on the gear body. Each oil outlet hole is connected to the oil storage cavity. Each oil outlet hole is provided with a pressing mechanism. Each pressing mechanism is slidably connected to two recovery mechanisms. Each recovery mechanism is fixedly connected to the inner wall of the oil storage cavity.

[0006] Each of the pressing mechanisms includes a pressing rod and a pressing plate;

[0007] The pressing rod is movably disposed in the corresponding oil outlet hole. The lower end of the pressing rod is fixedly connected to the upper surface of the pressing plate. The upper surface of the pressing plate is arc-shaped and is used in conjunction with the oil outlet hole. The pressing plate has two sliding holes, each of which is slidably connected to the corresponding recovery mechanism.

[0008] Each recovery mechanism includes a slide bar, a limit plate, and a spring;

[0009] The slide rod is slidably connected to the sliding hole on the pressing plate. One end of the slide rod is fixed to the inner wall of the oil storage cavity, and the other end of the slide rod is fixedly connected to the limiting plate. The spring is fitted on the slide rod, with one end of the spring fixedly connected to the lower end face of the pressing plate and the other end of the spring fixedly connected to the limiting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Effective lubrication: This device can automatically provide lubricating oil when gears mesh, ensuring that the gear meshing parts are adequately lubricated and reducing friction and wear.

[0012] 2. Reduced leakage: The design of this device, which seals the oil outlet after the pressing plate is reset, effectively prevents the leakage of lubricating oil in the non-engaging state, thus ensuring the effective use of lubricating oil.

[0013] 3. Extended service life: Because the gears receive adequate lubrication each time they mesh, wear between the gears is reduced, thus extending the service life of the gears.

[0014] 4. Improved work efficiency and stability: Improved lubrication makes the transmission system work more smoothly, improving work efficiency and stability, and reducing failures and downtime caused by friction and wear.

[0015] 5. Automatic lubrication mechanism: This device uses the pressure generated when the gears mesh to drive the movement of the pressing rod and pressing plate, achieving automatic lubrication without the need for an external power source or manual intervention.

[0016] 6. Compact structure: The device is compactly designed and integrated into the gear body, without taking up extra space, making it easy to install and maintain.

[0017] 7. High adaptability: This device can adapt to the needs of different working conditions and transmission systems, and can meet specific lubrication requirements by adjusting the type and amount of lubricating oil.

[0018] In summary, this utility model, through its unique design and automatic lubrication mechanism, achieves beneficial effects such as effective lubrication, reduced leakage, extended service life, improved work efficiency and stability, providing a strong guarantee for the reliable operation of the transmission system.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] This embodiment describes a self-lubricating transmission gear, including a gear body 1, an oil storage cavity 2, an oil outlet 3, multiple pressing mechanisms, and multiple restoring mechanisms;

[0023] The gear body 1 is provided with an oil storage chamber 2. There is an oil outlet hole 3 between every two adjacent teeth on the gear body 1. Each oil outlet hole 3 is connected to the oil storage chamber 2. Each oil outlet hole 3 is provided with a pressing mechanism. Each pressing mechanism is slidably connected to two recovery mechanisms. Each recovery mechanism is fixedly connected to the inner wall of the oil storage chamber 2.

[0024] Each of the pressing mechanisms includes a pressing rod 4 and a pressing plate 5;

[0025] The pressing rod 4 is movably disposed in the corresponding oil outlet 3. The lower end of the pressing rod 4 is fixedly connected to the upper end face of the pressing plate 5. The upper end face of the pressing plate 5 is arc-shaped and is used in conjunction with the oil outlet 3. The pressing plate 5 has two sliding holes, and each sliding hole is slidably connected to the corresponding recovery mechanism.

[0026] Each recovery mechanism includes a slide bar 6, a limiting plate 7, and a spring 8;

[0027] The slide rod 6 is slidably connected to the sliding hole on the pressing plate 5. One end of the slide rod 6 is fixed to the inner wall of the oil storage cavity 2, and the other end of the slide rod 6 is fixedly connected to the limiting plate 7. The spring 8 is fitted on the slide rod 6. One end of the spring 8 is fixedly connected to the lower end face of the pressing plate 5, and the other end of the spring 8 is fixedly connected to the limiting plate 7.

[0028] When using this invention, first install the device in the preset transmission system position. Through the pre-drilled hole on the gear body 1, use a lubricator or similar tool to inject an appropriate amount of lubricating oil into the oil storage chamber 2. After injection, seal the pre-drilled hole to prevent lubricating oil leakage. When the gear body 1 engages with other gears, the teeth of the other gears will contact the pressing rod 4 on the gear body 1 and generate pressure. Under this pressure, the pressing rod 4 will move along the oil outlet 3 into the oil storage chamber 2. Since the lower end of the pressing rod 4 is fixedly connected to the pressing plate 5, the pressing plate 5 will also move within the oil storage chamber 2. During this movement, the pressing plate 5 will slide along the sliding rod 6. At this time, the spring 8 mounted on the sliding rod 6 is compressed by the pressing plate 5, and the spring 8 stores elastic potential energy. When the engagement of the gear body 1 with other gears ends, the external force applied to the pressing rod 4 disappears. At this time, the compressed... Spring 8 releases its elastic potential energy, generating a reverse elastic force that pushes the pressing plate 5 along the slide rod 6 toward the oil outlet 3 to reset. During the reset process, the pressing plate 5 squeezes lubricating oil into the gap between the pressing rod 4 and the inner wall of the oil outlet 3. The lubricating oil is squeezed out through this gap and adheres to the tooth surface of the gear body 1. When the gear body 1 meshes with other gears again, the lubricating oil adhering to the gear body 1 will be transferred to the other gears meshing with it during the relative movement of the two gears, thereby achieving lubrication of the gear meshing parts. At the same time, since the pressing plate 5 will block the oil outlet 3 after reset, it can effectively prevent the lubricating oil in the oil storage chamber 2 from leaking in the non-meshing state, ensuring the effective use of lubricating oil, and ensuring that the gears can obtain an appropriate amount of lubrication each time they mesh, reducing friction and wear between gears, extending the service life of the gears, and improving the working efficiency and stability of the transmission system.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention.
