Description

Technical Field

[0001] The utility model relates to the technical field of gear boxes, in particular to a gear box for a high-speed motor. Background Art

[0002] The gearbox of a high-speed motor is a transmission device used to adjust the motor's output speed and torque. It typically consists of multiple gears, bearings, a housing, and a lubrication system. Its core function is to achieve speed reduction or acceleration through gear meshing, while also improving transmission efficiency and stability.

[0003] When the gears in the gearbox rotate, friction will occur between the contact surfaces. In order to reduce the friction, the gearbox needs to be lubricated regularly. The lubricating oil forms a protective film on the contact surface of the gears to reduce the friction coefficient. However, when adding lubricating oil regularly, it is necessary to inject oil into the gearbox from the outside, which is inconvenient. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The utility model provides Figure 1-4 The gearbox of a high-profile motor shown in the figure includes a gearbox body 1, an oil storage box 2, a partition 3, an oil inlet mechanism 5 and a lubricating mechanism 6. The top of the inner wall of the gearbox body 1 is fixedly connected to the oil storage box 2, and the partition 3 is fixedly connected to the inside of the oil storage box 2. The partition 3 is used to separate the oil storage box 2 into two cavities. A one-way valve 4 is embedded in the inside of the partition 3. The one-way valve 4 is used to connect the two cavities. The oil inlet mechanism 5 is provided on the gearbox body 1 for adding lubricating oil to the oil storage box 2. The lubricating mechanism 6 is provided inside the oil storage box 2 for limiting the loosening of the oil inlet mechanism 5 and adding lubricating oil. The oil storage box 2 is divided into two cavities by the partition 3, one for storing oil and the other for delivering oil, so that the transmission gear inside the gear box body 1 can be directly added with lubricating oil through the lubricating mechanism 6, so that there is no need to add oil from the outside every time lubrication work is performed, which improves the convenience of gear box lubrication operation. After the lubricating oil is used up, the sealing cover 52 in the oil inlet mechanism 5 can be opened to add oil, and after refueling, the sealing cover 52 is limited by the limit ring 67 in the lubricating mechanism 6, thereby ensuring the stability of the oil inlet mechanism 5 and facilitating use.

[0036] Specifically, the oil inlet mechanism 5 includes an oil inlet pipe 51 and a sealing cover 52. The oil inlet pipe 51 is fixedly connected to the gear box body 1. The outer wall of the oil inlet pipe 51 is provided with an external thread. The sealing cover 52 is threadedly connected to the oil inlet pipe 51. The sealing cover 52 can be opened by rotating to expose the top of the oil inlet pipe 51, so that lubricating oil can be added to the interior of the oil storage box 2 from the outside. There is no need to add oil from the outside every time lubrication work is performed, which improves the convenience of gear box lubrication operation.

[0037] Specifically, the lubrication mechanism 6 includes a piston plate 61, a pull rod 62, a compression spring 63 and an oil filling assembly 64. The piston plate 61 is arranged between the oil storage box 2 and the partition plate 3. One end of the pull rod 62 is fixedly connected to the piston plate 61, and the other end of the pull rod 62 is slidably and interlaced with the gear box body 1. The cross-section of the pull rod 62 is T-shaped, and the compression spring 63 is sleeved on the outside of the pull rod 62. One end of the compression spring 63 is fixedly connected to the piston plate 61, and the other end of the compression spring 63 is fixedly connected to the top of the inner wall of the gear box body 1. The compression spring 63 always provides a stable elastic force to the piston plate 61, so that the piston plate 61 can be kept inside a smaller oil delivery cavity. When the piston plate 61 is pulled by the pull rod 62, the lubricating oil inside the oil storage cavity can be extracted through the one-way valve 4, so that the gears inside the gear box body 1 are lubricated through the oil filling assembly 64. The oil filling assembly 64 is arranged at the bottom end of the oil storage box 2, and is used to add lubricating oil to the inside of the gear box body 1.

[0038] Furthermore, the lubricating mechanism 6 also includes a rotating plate 65, a limiting rod 66 and a limiting ring 67. The rotating plate 65 is rotatably sleeved on the outside of the pull rod 62. The top of the gear box body 1 is symmetrically provided with a limiting hole, and the inner wall of the limiting hole is provided with an arc groove. The limiting rod 66 passes through the limiting hole and is slidably connected with the inner cavity of the arc groove. The cross-section of the limiting rod 66 is T-shaped, and the limiting ring 67 is fixedly sleeved on the outside of the rotating plate 65 to limit the loosening of the sealing cover 52. The compression spring 63 provides a stable downward elastic force to the pull rod 62 through the piston plate 61, so that after the limiting rod 66 passes through the limiting hole, the rotating plate 65 is used to rotate 90°, so that the limiting rod 66 can be penetrated into the inside of the arc groove. At this time, the limiting ring 67 just rests on the top of the sealing cover 52, avoiding the possibility of the sealing cover 52 loosening due to the vibration generated by the operation of the gear box, which is convenient for use.

[0039] Furthermore, a groove is symmetrically provided at the top of the rotating plate 65, and an anti-slip texture is provided on the inner wall of the groove. The provision of the anti-slip texture increases the friction between the operator and the inner wall of the groove, allowing the operator to better rotate and pull the rotating plate 65 by pinching the rotating plate 65 with his fingers.

[0040] Furthermore, the oil filling assembly 64 includes an oil filling pipe 641 and an oil filling nozzle 642. The oil filling pipe 641 is fixedly connected to the bottom end of the oil storage box 2. A through hole is opened at the bottom end of the oil storage box 2 for the circulation of lubricating oil. The oil filling nozzle 642 is equidistantly fixedly connected to the bottom end of the oil filling pipe 641. During the reciprocating vertical displacement of the piston plate 61, the lubricating oil inside the oil storage cavity can be pumped into the interior of the oil filling pipe 641 through the through hole, and the gears can be lubricated by the oil filling nozzles 642 arranged at equal intervals.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
