Description

Technical Field

[0001] The utility model relates to the technical field of gear shaft center oil supply structures, in particular to a variable speed oil supply structure for a gear shaft center. Background Art

[0002] The automobile transmission is a key component in the automobile. Generally, each shaft of the transmission is connected to the housing through bearings. At present, the transmission on the market often uses splash lubrication of lubricating oil. The lubricating oil is thrown up by the rotation of the gears, or forms oil mist, to lubricate other gears and bearings in the transmission. The bearings generally do not have auxiliary lubrication mechanisms; Patent No. CN202020793103.9 discloses an oil collection and lubrication structure for the gear shaft of a front-wheel drive two-speed transmission, which can effectively collect the lubricating oil inside the transmission and introduce it into the inner hole of the output gear shaft, and then discharge the lubricating oil to the needle bearing through the oil drain hole, so as to achieve full lubrication of the needle bearing, greatly improve the lubrication performance of the parts in the transmission, and improve work efficiency; However, since the speed of the lubricating oil entering the center of the gear shaft cannot change with the speed of the gear shaft, it can only be supplied with oil at a constant rate. If the gear shaft rotates at a high speed, the supply rate of the lubricating oil is easy to fail to keep up with the speed of the gear shaft. To this end, we propose a variable speed oil supply structure for the center of the gear shaft. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a variable speed oil supply structure for the axis of a gear shaft.

[0004] The technical solution adopted by the utility model to solve the technical problem is a variable speed oil supply structure for the axis of a gear shaft, comprising a shaft body, a disc cover is rotatably mounted on the outer end of the shaft body, and a shell seat is mounted on the end of the disc cover away from the shaft body, a magnetic suction disc is rotatably mounted on the end of the shell seat close to the disc cover, and a magnetic suction ring is rotatably mounted on the end of the disc cover close to the shell seat, and the magnetic suction ring and the magnetic suction disc are both equipped with magnetic suction blocks that are magnetically attracted to each other, and there are multiple groups of magnetic suction blocks;

[0005] A piston chamber and a cavity are arranged on the inner side of the shell seat, and an impeller body for extracting lubricating oil is rotatably installed on the inner side of the piston chamber, a coupling which is transmission-connected to the impeller body is installed on the inner side of the cavity, and the coupling is transmission-connected to the magnetic suction cup.

[0006] By adopting the above technical solution, when the gear shaft is used, the impeller body in the piston chamber inside the housing seat can rotate and generate suction force, and the lubricating oil is extracted by the suction force, so that the lubricating oil can be transported into the axis of the gear shaft to facilitate lubrication;

[0007] When the gear shaft rotates, it drives the magnetic ring on the inside of the disc cover to rotate, and the magnetic block inside the magnetic ring and the magnetic block inside the magnetic cup on the outer wall surface of the shell seat are attracted to each other, and under the magnetic attraction of the two, the magnetic cup rotates with the rotation of the magnetic ring, and then the magnetic cup drives the impeller body to rotate through the coupling, and the impeller body changes with the rotation speed of the shaft, so that the oil supply rate also changes accordingly.

[0008] Specifically, a flow-guiding hose is arranged between the oil outlet of the piston chamber and the oil inlet of the disc cover.

[0009] By adopting the above technical solution, the hose can conveniently guide the lubricating oil entering the piston chamber, so that the lubricating oil can conveniently enter between the disc cover and the shell seat, and can conveniently pass through the hole in the magnetic ring and enter the axis inside the shaft body under continuous pressure.

[0010] Specifically, a filter ring is threadedly installed between the outer wall of the shell seat and the piston chamber.

[0011] By adopting the above technical solution, the filter ring can easily intercept metal debris and debris mixed in the lubricating oil, so that the impeller body in the piston chamber can operate more stably.

[0012] Specifically, one end of the filter ring located outside the shell seat is provided with a slot, and there are multiple groups of slots.

[0013] By adopting the above technical solution, the grooves on the surface of the filter ring make the filter ring easy to disassemble and replace.

[0014] Specifically, plugs are screwed onto the outer wall surface of the shell seat and the outer wall surface of the disc cover.

[0015] By adopting the above technical solution, the plug is easy to disassemble and assemble, and the internal structure of the shell seat and the disc cover is convenient to clean.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of the disc cover, the shell seat, the piston chamber and the impeller body. When the gear shaft is in use, the impeller body in the piston chamber inside the shell seat can rotate and generate suction force, and the suction force is used to extract the lubricating oil, so that the lubricating oil can be transported into the axis of the gear shaft to facilitate lubrication.

[0018] 2. The technical solution of the present application is designed with a coupling, a magnetic suction cup, a magnetic suction ring and a magnetic suction block. When the gear shaft rotates, it is convenient to drive the magnetic suction ring on the inner side of the disc cover to rotate, and the magnetic suction block inside the magnetic suction ring and the magnetic suction block inside the magnetic suction cup on the outer wall surface of the shell seat are magnetically attracted to each other, and under the magnetic attraction of the two, the magnetic suction cup rotates with the rotation of the magnetic suction ring, and then the magnetic suction cup drives the impeller body to rotate through the coupling, and the impeller body changes with the rotation speed of the shaft body, thereby changing the oil supply rate accordingly.

[0026] When the gear shaft is in use, the impeller body 6 in the piston chamber 4 inside the housing seat 3 can rotate and generate suction force, and the lubricating oil is extracted by the suction force, so that the lubricating oil can be transported into the axis of the gear shaft to facilitate lubrication;

[0027] When the gear shaft rotates, it is convenient to drive the magnetic ring 9 on the inner side of the disc cover 2 to rotate, and the magnetic block 10 inside the magnetic ring 9 and the magnetic block 10 inside the magnetic cup 8 on the outer wall surface of the shell seat 3 are mutually attracted, and under the magnetic attraction of the two, the magnetic cup 8 rotates with the rotation of the magnetic ring 9, and then the magnetic cup 8 drives the impeller body 6 to rotate through the coupling 7, and the impeller body 6 changes with the rotation speed of the shaft body 1, so that the oil supply rate also changes accordingly.

[0028] like Figure 1 and Figure 2 As shown, a fluid-guiding hose 11 is installed between the oil outlet end of the piston chamber 4 and the oil inlet end of the disc cover 2.

[0029] When in use, the hose 11 facilitates the diversion of the lubricating oil into the piston chamber 4, so that the lubricating oil can easily enter between the disc cover 2 and the shell seat 3, and can easily pass through the hole in the magnetic ring 9 and enter the axis inside the shaft body 1 under continuous pressure.

As the lubricating oil continues to enter, the lubricating oil can easily pass through the hole in the middle of the magnetic ring 9 and enter the axis inside the shaft body 1, so as to facilitate the oil supply to the axis, and the impeller body 6 can easily change with the rotation speed of the shaft body 1, so that the oil supply rate also changes accordingly. When the rotation speed of the shaft body 1 is fast, the oil supply efficiency is faster, and when the rotation speed of the shaft body 1 is slow, the oil supply efficiency will become slower.
