Description

Technical Field

[0002] A gearbox is a mechanical device used to transmit power and speed. It consists of multiple gears and transmits power through the meshing and rotation of the gears, and changes the speed and torque of the input shaft.

[0003] The gearbox is connected to the motor, and the output torque of the motor can be changed through the gearbox. The motor acts as a power source to provide energy for the system, and the gearbox efficiently converts the power of the motor into the required speed and torque through its sophisticated gear transmission.

[0004] 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 gear 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. For this reason, we propose a lubrication device for a motor gearbox. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The utility model provides Figure 1-Figure 3 A lubrication device for a motor gearbox is shown.

[0039] Embodiment 1: It includes a gearbox body 101, an oil storage mechanism, an oil spraying mechanism and an oil filling mechanism. The oil storage mechanism is arranged inside the gearbox body 101, the oil spraying mechanism is arranged at the bottom of the oil storage mechanism, and the oil filling mechanism is arranged inside the oil storage mechanism. The oil filling mechanism is used to spray the lubricating oil in the oil storage mechanism from the oil spraying mechanism. The lubricating oil is stored inside the gearbox body 101 through the oil storage mechanism. When the gears in the gearbox need to be lubricated, a small part of the lubricating oil in the oil storage mechanism is sprayed from the oil spraying mechanism onto the gears through the oil filling mechanism to lubricate the gears. Therefore, there is no need to add oil from the outside every time lubrication work is performed, which improves the convenience of gearbox lubrication operation.

[0040] Among them, the oil storage mechanism includes a box body 201 and a partition plate 202. The box body 201 is fixedly connected to the top of the inner wall of the gear box body 101. An oil inlet mechanism is arranged on one side of the box body 201. The partition plate 202 is fixedly connected to the inner wall of the box body 201. The inner cavity of the box body 201 is divided into an oil storage cavity 203 and an oil filling cavity 204 through the partition plate 202. The oil filling mechanism is arranged inside the oil filling cavity 204. A large amount of lubricating oil is stored inside the oil storage cavity 203.

[0041] Among them, the oil injection mechanism includes a connecting hole 301 and an atomizing nozzle 302. The connecting hole 301 is opened at the bottom end of the box body 201, and the atomizing nozzle 302 is installed inside the connecting hole 301. Through the cooperation of the oil injection mechanism, a small amount of lubricating oil in the oil injection chamber 204 is sprayed toward the gears in the gear box body 101 through the atomizing nozzle 302, and the atomizing nozzle 302 will spray the lubricating oil in an atomized form, so that the lubricating oil can be more evenly covered on the gears in the gear box body 101, thereby improving the lubrication effect.

[0042] Among them, the oil injection mechanism includes a one-way valve 402, a piston block 401 and an operating mechanism. The one-way valve 402 is installed at the bottom end of the partition plate 202, the outer wall of the piston block 401 is slidably connected to the inner wall of the oil injection chamber 204, and the operating mechanism is arranged at the top of the piston block 401. By moving the piston block 401 upward, the space below the piston block 401 in the oil injection chamber 204 is in a negative pressure state, so that the lubricating oil in the oil storage chamber 203 enters the bottom of the piston block 401 through the one-way valve 402, and then the piston block 401 moves downward, and the lubricating oil can be sprayed out through the atomizing nozzle 302 for lubrication.

[0043] Among them, the operating mechanism includes a movable rod 502, a movable hole 501, a circular hole 601, a pull ring 602 and an extrusion piece. The bottom end of the movable rod 502 is fixedly connected to the top of the piston block 401. The movable hole 501 is opened at the top of the gear box body 101. The outer wall of the movable rod 502 is movably connected with the inner wall of the movable hole 501. The circular hole 601 is opened at the end of the movable rod 502. The pull ring 602 is inserted into the inner wall of the circular hole 601. The extrusion piece is arranged inside the oil filling chamber 204. By pulling the pull ring 602 above the gear box body 101, the movable rod 502 can be moved. The movement of the movable rod 502 can drive the piston block 401 to move, thereby improving the convenience of the oil filling mechanism.

[0044] Among them, the extrusion part includes an extrusion spring 701, which is arranged at the top of the piston block 401, and the extrusion spring 701 is sleeved on the outer wall of the movable rod 502. When the piston block 401 is pulled upward, the extrusion spring 701 is compressed, which can make the piston block 401 always have a tendency to move downward, so that the piston block 401 can automatically move downward to spray the lubricating oil below it through the atomizing nozzle 302, further improving the convenience of operating the oil injection mechanism.

[0045] Embodiment 2: Compared with Embodiment 1, the oil inlet mechanism includes an oil inlet pipe 801 and a sealing cover 802. One end of the oil inlet pipe 801 is fixedly connected with the outer wall of the box body 201, and the other end of the oil inlet pipe 801 passes through the inner wall of the gear box body 101 and extends to the outside of the gear box body 101. The sealing cover 802 is threadedly sleeved on the outer wall of the oil inlet pipe 801. When the lubricating oil in the oil storage chamber 203 is insufficient, the sealing cover 802 is unscrewed, and oil can be added to the oil storage chamber 203 through the oil inlet pipe 801, so that the oil storage chamber 203 can store a large amount of lubricating oil, and then the gear box can be lubricated multiple times through the oil filling mechanism.
