Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a speed reducer with self-lubricating function. Background Technology

[0002] A speed reducer is a mechanical transmission device used to reduce speed and increase torque. It mainly consists of gears, a housing, bearings, and other key components, enclosed within a rigid casing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. Speed ​​reducers play a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and are widely used in various industrial and civil equipment to meet the needs of different driven machines.

[0003] The shaft of a speed reducer generates a large amount of heat during high-speed rotation, typically requiring lubrication for cooling. Existing speed reducers require manual, continuous addition of lubricating oil during operation, resulting in low efficiency. Furthermore, the maintenance cover is usually secured with multiple sets of bolts, necessitating tool disassembly and reassembly in case of malfunction, further complicating the process. Therefore, we propose a speed reducer with self-lubricating capabilities. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a speed reducer with self-lubricating function, which solves the problems of low work efficiency caused by the need for manual and continuous addition of lubricating oil during the operation of the speed reducer, and the low work efficiency caused by the need for tools to disassemble and reassemble the cover plate which is usually installed and fixed with multiple sets of bolts when the speed reducer fails.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-lubricating speed reducer includes a mounting plate. A speed reducer body is fixedly connected to the top of the mounting plate. A fixing ring is mounted on the outer side of the speed reducer body. An oil reservoir is fixedly connected to the outer side of the fixing ring. Fixing blocks are fixedly connected at equal intervals to the inner wall of the fixing ring. An oil guide pipe is fixedly connected to one side of each fixing block. The oil guide pipe communicates with the oil reservoir via a connecting pipe. Brush bristles are provided at equal intervals at the bottom of the oil guide pipe. A cover plate is provided on the top of the speed reducer body. A fixing seat is fixedly connected to the top of the cover plate. A sliding plate is symmetrically slidably connected inside the fixing seat. Insert blocks are fixedly connected at equal intervals to one side of the sliding plate. Limit seats are symmetrically fixedly connected to the top of the speed reducer body. Slots for engaging with the insert blocks are provided at equal intervals inside the limit seats. Lubricating oil enters the oil guide pipe through the connecting pipe and is then applied to the shaft of the speed reducer body by the brush bristles, eliminating the need for continuous manual addition of lubricating oil.

[0007] Preferably, the top of the oil reservoir is threaded with a sealing cap, which facilitates opening the oil reservoir and adding lubricating oil into the reservoir.

[0008] Preferably, the inner wall of the fixed base is symmetrically slidably connected with a slider, and the outer side of the slider is symmetrically rotatably connected with a connecting rod. The connecting rod is rotatably connected to the sliding plate. The movement of the slider drives the connecting rod to rotate, and the rotation of the connecting rod drives the sliding plate to move.

[0009] Preferably, the slider is in contact with the inner wall of the fixed base, and its movement can be limited by the contact between the slider and the inner wall of the fixed base.

[0010] Preferably, the fixed base is internally rotatably connected to a bidirectional lead screw, the slider is threadedly connected to the bidirectional lead screw, and a knob is fixedly connected to one end of the bidirectional lead screw. The knob drives the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw drives the slider to slide.

[0011] Preferably, anti-slip protrusions are fixedly connected at equal intervals on the outer side of the knob. The anti-slip protrusions can increase the friction and facilitate the rotation of the knob.

[0012] This invention provides a speed reducer with self-lubricating function. Compared with the prior art, it has the following advantages:

[0013] 1. This self-lubricating speed reducer achieves the function of applying lubricating oil to the shaft of the speed reducer body by setting a retaining ring, oil reservoir, sealing cover, connecting pipe, oil guide pipe and brush bristles, eliminating the need for continuous manual addition of lubricating oil and resulting in high working efficiency.

[0014] 2. This self-lubricating reducer features a knob, a two-way lead screw, a slider, a connecting rod, a sliding plate, a plug, a limit seat, and a slot, enabling quick disassembly and assembly of the cover plate. This facilitates internal maintenance of the reducer body and makes operation convenient. Attached Figure Description

A fixing ring 2 is mounted on the outer side of the speed reducer body 7. An oil reservoir 9 is fixedly connected to the outer side of the fixing ring 2. Fixing blocks 11 are fixedly connected at equal intervals to the inner wall of the fixing ring 2. An oil guide pipe 8 is fixedly connected to one side of the fixing block 11. The oil guide pipe 8 is connected to the oil reservoir 9 through a connecting pipe 12. Brush bristles 10 are provided at equal intervals at the bottom of the oil guide pipe 8. A cover plate 3 is provided on the top of the speed reducer body 7. A fixing seat 5 is fixedly connected to the top of the cover plate 3. A sliding plate 16 is symmetrically slidably connected inside the fixing seat 5. Brush bristles 10 are fixedly connected at equal intervals to one side of the sliding plate 16. The top of the reducer body 7 is symmetrically and fixedly connected to the insert block 19 and the limiting seat 6. The limiting seat 6 has slots 20 that are equidistantly opened inside to cooperate with the insert block 19. According to the working time required by the reducer body 7, the appropriate amount of lubricating oil is added to the oil reservoir 9. The lubricating oil enters the oil guide pipe 8 through the connecting pipe 12 and the shaft of the reducer body 7 is coated with lubricating oil by the brush 10. There is no need for manual continuous addition of lubricating oil, which has high working efficiency. The insert block 19 is moved by the sliding plate 16, so that the insert block 19 moves into or out of the slot 20, which facilitates the quick disassembly and assembly of the cover plate 3 and facilitates the internal maintenance of the reducer body 7.

[0024] Furthermore, the top of the oil reservoir 9 is threaded with a sealing cap 13, which facilitates the opening of the oil reservoir 9 and the addition of lubricating oil into the oil reservoir 9.

[0025] Furthermore, the inner wall of the fixed base 5 is symmetrically slidably connected with a slider 15, and the outer side of the slider 15 is symmetrically rotatably connected with a connecting rod 18. The connecting rod 18 is rotatably connected to the sliding plate 16. The movement of the slider 15 drives the connecting rod 18 to rotate, and the rotation of the connecting rod 18 drives the sliding plate 16 to move.

[0026] Furthermore, the slider 15 is in contact with the inner wall of the fixed base 5, and its movement can be limited by the contact between the slider 15 and the inner wall of the fixed base 5.

[0027] Furthermore, the fixed base 5 is internally rotatably connected to a bidirectional lead screw 17, and the slider 15 is threadedly connected to the bidirectional lead screw 17. A knob 4 is fixedly connected to one end of the bidirectional lead screw 17. The knob 4 drives the bidirectional lead screw 17 to rotate, and the rotation of the bidirectional lead screw 17 drives the slider 15 to slide.

[0028] Furthermore, anti-slip protrusions 14 are fixedly connected at equal intervals on the outer side of the knob 4. The anti-slip protrusions 14 can increase the friction and make it easier to rotate the knob 4.

[0029] Working principle:

[0030] During use, add the appropriate amount of lubricating oil to the oil reservoir 9 according to the required working time of the reducer body 7. The lubricating oil enters the oil guide pipe 8 through the connecting pipe 12, and the shaft of the reducer body 7 is coated with lubricating oil by the brush 10. There is no need for manual continuous addition of lubricating oil, which has high working efficiency. When the reducer body 7 needs to be inspected, turn the knob 4. The knob 4 drives the double-acting screw 17 to rotate. The rotation of the double-acting screw 17 drives the slider 15 to slide along the inner wall of the fixed seat 5. The movement of the slider 15 drives the connecting rod 18 to rotate. The rotation of the connecting rod 18 drives the sliding plate 16 to move. The sliding plate 16 drives the insert block 19 to move, so that the insert block 19 moves into or out of the slot 20, which facilitates quick disassembly and assembly of the cover plate 3 and facilitates internal inspection of the reducer body 7. The operation is convenient.
