Description

Technical Field

[0001] The utility model relates to the technical field of gearbox gears, in particular to a planetary gearbox gear. Background Art

[0002] The variable gears generally used in the gearbox body are called gearbox gears. Gearbox gears often work under high speed, high load, and constant alternation of speed and load.

[0003] For example, the patent (CN216279271 U) discloses a self-lubricating gearbox gear, including a gear body with an external tooth portion, an axial hole is opened in the central part of the gear body, annular grooves are opened at both end faces of the gear body, an oil storage ring cavity for storing lubricating oil is opened in the gear body, a plurality of oil filling holes are opened at the bottom of the annular groove on one end face of the gear body, a plurality of oil passages connected with the tooth bottom of the external tooth portion are opened on the inner peripheral wall of the oil storage ring cavity, an oil outlet assembly for unidirectional outflow of lubricating oil is arranged in the oil passage at one end of the tooth bottom of the external tooth portion, and the oil outlet assembly is composed of a limit member, a return spring and a protrusion for limiting the return spring.

[0004] When using the above technology, it was found that the following technical problems exist in the prior art: the prior art uses the centrifugal force rotation to drive the return spring to contract. At this time, the gap and the gap generated by the boss and the protrusion are used to allow the lubrication inside the oil channel to seep out, which results in only a small amount of lubricating oil seeping out. In addition, the prior art does not have a filter, which is not convenient for screening the solids in the lubricating oil, resulting in the blockage of the oil outlet. For this reason, we design a planetary gearbox gear to provide another technical solution to the above technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide a planetary gearbox gear to address the above technical problems. The lubricating oil is poured into the oil storage tank. When the device rotates rapidly, the centrifugal force generated drives the lubrication mechanism to disengage from the mounting groove, thereby forming a gap. The lubricating oil flows into the inner side of the oil chamber along the mounting groove and the gap. As the centrifugal force of rotation moves, the lubricating oil flows into the inner side of the oil outlet along the direction of the annular guide plate, which is convenient for lubricating the meshing teeth when they mesh with the external gears.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] As a preferred embodiment of the planetary transmission gear provided by the utility model, the lubrication mechanism includes a support frame, an annular recessed block is fixed at one end of the mounting groove close to the oil storage tank, a support frame is fixed on the inner side of the mounting groove, a sliding rod is slidably connected inside the support frame, a circular baffle plate is fixed at one end of the sliding rod, one end of the circular baffle plate is slidably connected to the annular recessed block, a sealing block is fixed to the other end of the sliding rod, the outer side of the sealing block is slidably connected to the mounting groove, and a spring is sleeved on the outer side of the sliding rod.

[0009] As a preferred implementation of the planetary transmission gear provided by the utility model, one end of the spring is fixed to the circular baffle convex plate, and the other end of the spring is fixed to the support frame.

[0010] As a preferred embodiment of the planetary transmission gear provided by the utility model, a filter plate is fixed to one end of the annular recessed block close to the oil storage tank.

[0011] As a preferred embodiment of the planetary gearbox gear provided by the utility model, protective covers are fixed to the top and bottom ends of the annular mounting block, the main body and the shaft hole, and oil filling holes and oil outlet holes are opened at the top and bottom ends of the protective cover, and the inner sides of the oil filling holes and the oil outlet holes are respectively threadedly connected with A sealing bolts and B sealing bolts.

[0012] As a preferred embodiment of the planetary transmission gear provided by the utility model, there are three annular guide plates and three mounting grooves, a sealing gasket A is fixed to the outside of the sealing block, and a sealing gasket B is fixed between one end of the circular baffle convex plate and the annular concave block.

[0013] It can be seen without a doubt that the above-mentioned technical solution of the present application can definitely solve the technical problem to be solved by the present application.

[0014] At the same time, through the above technical solutions, the utility model has at least the following beneficial effects:

[0015] The utility model provides a planetary transmission gear, which filters the lubricating oil in the oil storage tank through a filter plate to prevent solids in the lubricating oil from clogging the oil outlet, and the centrifugal force generated by rapid rotation drives the lubrication mechanism to separate from the mounting groove, so that the lubricating oil flows out along the mounting groove, the annular guide plate and the oil outlet through the gap, and then when the meshing teeth are meshed with the external gears, a certain lubrication effect is achieved, the friction between the meshing teeth and the external gears is reduced, and the service life of the device is increased.

When the device rotates rapidly, the centrifugal force generated drives the lubricating mechanism to separate from the mounting groove 9, thereby forming a gap. The lubricating oil flows into the inner side of the oil chamber 15 along the mounting groove 9 and the gap. With the centrifugal force of rotation, the lubricating oil flows into the inner side of the oil outlet 4 along the direction of the annular guide plate 7, so as to play a certain lubricating effect when the meshing teeth 3 are meshed with the external gear.

When not in operation, the elastic force of the spring 19 drives the circular baffle convex plate 17 to seal with the annular concave block 16, and the slide rod 21 to seal with the mounting groove 9;

[0031] One end of the circular baffle convex plate 17 is slidably connected to the annular concave block 16, a sealing block 20 is fixed to the other end of the slide rod 21, the outer side of the sealing block 20 is slidably connected to the mounting groove 9, a spring 19 is sleeved on the outer side of the slide rod 21, one end of the spring 19 is fixed to the circular baffle convex plate 17, and the other end of the spring 19 is fixed to the support frame 18, and a filter plate 14 is fixed to the end of the annular concave block 16 close to the oil storage tank 8;

At this time, the annular concave block 16 is separated from the circular baffle plate 17, and a gap is generated to form an oil passage. At this time, the lubricating oil in the oil storage tank 8 passes through the inside of the filter plate 14 and flows into the oil chamber 15 along the inner side of the mounting groove 9;

At this time, the annular recess 16 is disengaged from the circular baffle convex plate 17, and a gap is generated to form an oil channel. At this time, the lubricating oil inside the oil storage tank 8 passes through the inside of the filter plate 14 and flows into the oil chamber 15 along the inner side of the mounting groove 9.
