Description

Technical Field

[0001] This utility model relates to the field of gear technology, specifically to a rust-proof gear equipped with an oil outlet device. Background Technology

[0002] Gears are often used as transmission components in mechanical structures, working in conjunction with other gears or racks to transmit power and torque. To reduce wear and corrosion of gears, it is often necessary to add lubricating oil to the gears during operation to create an oil film. However, most gears are lubricated externally, which often fails to reach the meshing tooth angles, thus affecting the effectiveness of the lubrication.

[0003] An existing patent (application number: CN202023000028.5) discloses an engine gear capable of automatic oil filling. This gear has a plug inside the oil outlet. When the engine gear rotates at high speed, the plug, under centrifugal force, compresses a telescopic spring, causing the plug to disengage and block the oil outlet. This facilitates timely oil filling during high-speed engine gear rotation, thereby reducing friction between the gears and extending their service life. However, this type of engine gear, which relies on the elastic deformation of the spring to adjust the plug's sealing of the oil outlet, is prone to unstable oil supply due to spring deformation or failure to be compressed by the plug.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2A rust-proof gear equipped with an oil outlet device may include two half-gear modules 10, two oil storage modules 20, an oil suction lubrication assembly 30, a sealing cap 40, and fasteners 50. The two half-gear modules 10 are symmetrically connected and fixed to each other by the fasteners 50 to form a complete gear. The two oil storage modules 20 are symmetrically arranged in the cavity between the two half-gear modules 10, and an inner cavity for holding lubricating oil is formed between the two oil storage modules 20. The oil suction lubrication assembly 30 is disposed in the cavity between the two oil storage modules 20, and the oil suction lubrication assembly 30 has multiple branches extending through the two oil storage modules 20 and reaching the root of the gear teeth. The oil suction lubrication assembly 30 can be made entirely of a high-molecular polymer fiber material with multiple microporous structures inside. After absorbing lubricating oil, it can use its multiple branches to guide the lubricating oil to the root of the gear teeth. An oil inlet is also formed on the oil storage module 20. The sealing cap 40 is used to seal the oil inlet under normal conditions, and lubricating oil can be added through the oil inlet after removal.

[0024] See Figure 3 The half-gear module 10 includes a disk 11 and a plurality of teeth 12 formed on the outer wall of the disk 11. A cavity 13 is formed in the middle of the disk 11, and the cavities 13 in the two half-gear modules 10 are used together to accommodate the oil storage module 20. A plurality of first connecting holes 15 are also formed on the inner wall of the cavity 13 to cooperate with fasteners 50, so that when the two half-gear modules 10 are assembled using fasteners such as bolts and nuts, the bolts can pass through the first connecting holes 15 and the nuts can be tightened to fix the two half-gear modules 10. A plurality of positioning blocks 16 are also formed on the inner wall of the cavity 13 for positioning and installation of the oil storage module 20. A plurality of first slots 14 are formed at the outer edge of the cavity 13, and each first slot 14 extends to the bottom of two adjacent teeth 12, through which branches of the oil suction lubrication assembly 30 can pass.

[0025] See Figure 4The oil storage module 20 includes a base 21 and a central reinforcing block 22 formed at the center of the base 21. An oil storage cavity 23 is formed between the base 21 and the central reinforcing block 22, and the oil storage cavities 23 in both oil storage modules 20 are used to contain lubricating oil. An oil inlet is also formed on the side of the base 21 facing the half gear module 10, which communicates with the oil storage cavity 23. An opening coaxially aligned with the oil inlet is also formed on the inner wall of the cavity 13. A sealing cap 40 is detachably fastened between the oil inlet and the opening of the cavity 13. Several positioning grooves 26 are formed on the central reinforcing block 22 to cooperate with the positioning block 16, so that the oil storage module 20 can be positioned during placement and assembly. Several second connecting holes 25 are formed on the central reinforcing block 22 to cooperate with the fasteners 50. The second connecting holes 25 can be coaxially distributed with the adjacent first connecting holes 15 so that the fasteners can pass through. Multiple second slots 24 are formed at the outer edge of the base 21, which communicate with the oil storage cavity 23. Each second slot 24 communicates with the adjacent first slot 14, so that the branches of the oil suction lubrication assembly 30 can pass through the second slot 24.

[0026] See Figure 5 The oil-absorbing lubrication assembly 30 includes an oil-absorbing section 31 and multiple outlet sections 32. The oil-absorbing section 31 is arranged in an annular shape between two oil storage chambers 23 and is used to absorb lubricating oil. The multiple outlet sections 32 are uniformly formed radially on the outside of the oil-absorbing section 31, forming multiple branches of the oil-absorbing lubrication assembly 30. Each outlet section 32 passes through an adjacent first slot 14 and second slot 24, and the outlet section 32 can fill the gap between two opposing second slots 24 to prevent lubricating oil from flowing out directly through the second slot 24. Instead, the lubricating oil is slowly and continuously discharged to the root region of the gear through the outlet section 32. The oil-absorbing lubrication assembly 30 can be made of, for example, polypropylene fiber material, which has hydrophobic and oleophilic properties, and the fiber surface is rough with a large number of micropores and grooves, which can adsorb and discharge lubricating oil through capillary action.
