Description

Technical Field

[0001] A transmission mechanism with lubrication and a transmission method of the present invention belong to the technical field of mechanical transmission mechanisms. Background Art

[0002] The power transmission between machines is simply referred to as transmission, which is commonly found in mechanical structures. According to different driving energy sources, transmissions can be divided into three categories: mechanical transmission, fluid transmission, and electric drive.

[0003] The power source of mechanical transmission is mechanical components, including both meshing transmissions such as gear transmission and chain drive, and friction transmissions such as friction wheel drive and belt drive; the power source of fluid transmission is liquid or gas, including hydraulic transmission relying on the action of liquid static pressure, hydrodynamic transmission relying on the action of liquid power, and pneumatic transmission relying on the action of gas pressure; the power source of electric drive is electric energy, which is converted into mechanical energy to drive transmission components.

[0004] Among various transmission structures, the mechanical transmission structure is the simplest, with the lowest cost and the most common. The chainring and chain on a bicycle are typical meshing transmissions. The characteristic of this transmission structure is that there is rigid contact between two mutually transmitting components, which is more prone to wear compared to other transmission structures.

[0005] Regarding the problems that the two components of meshing transmission have rigid contact on the surface, small contact area, and are more prone to mechanical wear, and that when the two components of meshing transmission are not precisely matched, they are prone to collision and cause component damage, the invention patent "Magnetic Gear Transmission Mechanism" with the application number 201510665847.6 provides a solution. A magnetic gear transmission mechanism is designed, which includes a pair of mutually meshing gears. The teeth of the gears are made of ferromagnetic material, and the inner part of the gear body contains circumferentially evenly distributed permanent magnets; each permanent magnet is magnetized radially along the gear, and the same poles of each permanent magnet are radially outward or radially inward in unison; this transmission mechanism can weaken the rigid contact and collision between the mutually meshing teeth, thereby improving the durability of the gear transmission mechanism.

[0006] It can be seen that through structural improvement, the mechanical wear of meshing transmission can be reduced. However, the methods for reducing the mechanical wear of meshing transmission are not limited to structural improvement.

[0007] When we maintain a bicycle, we often apply lubricating oil to the chain. It can be seen that applying lubricating oil can also reduce the mechanical wear of meshing transmission. However, the above-mentioned prior art does not have a lubricating function, so its performance still has room for further improvement. Summary of the Invention

[0008] In order to further reduce the mechanical wear of meshing transmission, the present invention designs a transmission mechanism and a transmission method with lubrication. Not only does it have a lubrication design, and the meshing part is lubricated while the non-meshing part is not lubricated, with high lubrication efficiency, so it can further reduce the mechanical wear of the meshing structure, but also it has a design for recycling lubricating oil, and at the same time it has the technical feature of being conveniently connected to an external transmission structure.

[0009] The object of the present invention is achieved as follows:

[0012] The two rotating tubes are respectively fixedly sleeved with the cylindrical gear and the inner core having a lubrication function. The magnetic outer tooth ring is fixedly sleeved on the cylindrical surface of the inner core, and the magnetic outer tooth ring is meshed with the cylindrical gear; the oil tank is arranged on the side wall of the outer shell, and lubricating oil is contained in the oil tank, and the lubricating oil can be conveyed to the meshing cylindrical gear and inner core through the fixed short tube;

The cover is arranged at the front opening of the outer shell, and the cover and the outer shell are fixedly installed through a plurality of screws. Two inner plates are fixedly installed inside the outer shell, and the inner plates are rotatably installed with the rotating tube.

[0015] For the above-mentioned transmission mechanism with lubrication, an oil collecting hopper is arranged at the bottom of the outer shell. A filling port for replenishing lubricating oil is arranged at the top of the oil tank. A threaded cap for sealing is threadedly installed at the top of the filling port. A first pump body is also installed at the top of the oil tank. The inlet of the first pump body is fixedly sleeved with a third tube body, and the third tube body is arranged inside the oil tank. The outlet of the first pump body is fixedly sleeved with a first tube body, and the first tube body is fixedly connected to the top wall of the fixed short tube and is communicated with the fixed short tube.

[0016] A second pump body is arranged inside the fuel tank. The output end of the second pump body is fixedly sleeved with a second pipe body. One end of the second pipe body away from the second pump body is fixedly communicated and installed with a three-way pipe. A one-way valve is fixedly sleeved on the upper port of the three-way pipe. The top end of the one-way valve is fixedly communicated and installed with the bottom of a fixed short pipe. A suction pipe is fixedly sleeved on the lower port of the three-way pipe. The bottom end of the suction pipe extends into the inside of the oil receiving hopper.

[0017] In the above-mentioned transmission mechanism with lubrication, an inner cavity is formed inside the cylindrical gear. The inner cavity is communicated and installed with the rotating pipe. A plurality of tooth blocks for meshing with the magnetic outer gear ring are arranged around the cylindrical gear. An oil outlet groove is formed on the tooth block. The oil outlet groove is communicated and installed with the inner cavity through a guide hole. A guide rod is slidably fitted in the guide hole. One end of the guide rod is fixedly connected with an iron block. The iron block is embedded in the oil outlet groove. A rubber pressing pad is fixedly installed on the iron block. A first spiral spring in a compressed state is sleeved on the guide rod. One end of the first spiral spring is fixedly connected with the inner wall of the inner cavity, and the other end is fixedly connected with the rod surface of the guide rod. A blocking seat is fixedly installed in the oil outlet groove.

[0018] In the above-mentioned transmission mechanism with lubrication, a first inner frame and a second inner frame are fixedly installed inside the rotating pipe. A rotating rod is rotatably installed in the middle of the first inner frame and the second inner frame. A worm gear and two cams are fixedly sleeved on the rotating rod. The worm gear is meshed with a worm. The worm is hermetically rotatably installed inside the rotating pipe. One end of the worm is fixedly installed with a rotating knob. The rotating knob is arranged outside the rotating pipe. A guide groove is formed on the pipe wall of the rotating pipe. A positioning block is fitted in the guide groove with a gap. A notch is formed at one end of the positioning block. A roller is installed in the notch. The roller is rotatably installed on the positioning block and contacts the cam. Side blocks are fixedly installed on both sides of the end of the positioning block close to the cam. A second spiral spring is arranged between the side block and the inner wall of the rotating pipe. One end of the second spiral spring is fixedly connected with the side block, and the other end is fixedly connected with the inner wall of the rotating pipe. An outer connector is hermetically sleeved on the outer wall of the rotating pipe. A positioning groove for inserting the positioning block is formed on the inner wall of the outer connector to realize the interaction between the outer connector and the rotating pipe.

[0019] A transmission method with lubrication includes the following steps:

[0020] Step a, connection

[0021] The external external connection part sealing sleeve is sleeved at one end of the rotating pipe, and the guide groove is aligned with the positioning groove. The positioning block on the rotating pipe does not protrude from the guide groove and is still located inside the rotating pipe. After the socket installation, by turning the rotating knob, the worm rotates. Through the meshing between the worm and the worm gear, the rotating rod rotates, and the cam rotates synchronously. Through the action with the roller, the positioning block protrudes from the guide groove and is inserted into the mounting hole position on the external connection part, realizing the installation; there is a self-locking function between the worm gear and the worm, which can prevent the second spiral spring from causing the positioning block to retract into the guide groove again, improving the connection reliability;

[0022] Step b, Transmission

[0023] When one rotating pipe rotates, the magnetic external gear ring or the cylindrical gear rotates. Through the meshing between the magnetic external gear ring and the cylindrical gear, the other rotating pipe rotates, thus completing the transmission;

[0024] Step c, Lubrication

[0025] The first pump body pumps the lubricating oil in the fuel tank into the fixed short pipe and the rotating pipe successively through the third pipe body and the first pipe body, and then enters the inner cavity. At the meshing part of the magnetic external gear ring and the cylindrical gear, the magnetic external gear ring magnetically attracts the iron block, causing the iron block to move, opening the oil outlet groove, and the lubricating oil flows out from the oil outlet groove to lubricate the meshing magnetic external gear ring and cylindrical gear; under the blocking action of the blocking seat, it is prevented that the iron block falls out of the oil outlet groove. The iron block drives the guide rod to move in the guide hole. At the non-meshing part of the magnetic external gear ring and the cylindrical gear, the first spiral spring in the compressed state causes the iron block to reset;

[0026] Step d, Recycling

[0027] The lubricating oil flowing out from the oil outlet groove, after lubricating the meshing magnetic external gear ring and cylindrical gear, flows into the oil receiving hopper. Through the suction of the second pump body, the lubricating oil in the oil receiving hopper enters the suction pipe and flows into the fixed short pipe through the one-way valve or enters the second pipe body through the three-way pipe and then returns to the fuel tank, realizing the recycling;

[0028] Step e, Disassembly

[0029] By reversely turning the rotating knob, the worm rotates reversely. Through the meshing between the worm and the worm gear, the rotating rod rotates reversely, and the cam rotates synchronously in the reverse direction. The second spiral spring in the compressed state causes the positioning block to retract into the guide groove again, canceling the positioning of the rotating pipe and the external connection part. At this time, the external connection part is disassembled from the rotating pipe.

Specific Embodiment Six

[0068] The following are the specific implementation manners of the lubricating transmission method of the present invention.

[0069] The lubricating transmission method under this specific implementation manner includes the following steps:

[0070] Step a, connection

[0071] The external outer connector 39 is sleeved on one end of the rotating tube 3 in a sealed manner, and the guide groove 701 is aligned with the positioning groove. The positioning block 7 on the rotating tube 3 does not extend out of the guide groove 701 and is still located inside the rotating tube 3. After the sleeve installation, by turning the rotating knob 5, the worm 33 rotates. Through the meshing between the worm 33 and the worm gear 32, the rotating rod 31 rotates, and the cam 35 rotates synchronously. Through the interaction with the roller 36, the positioning block 7 is extended out of the guide groove 701 and inserted into the installation hole position on the external connector, realizing the installation; there is a self-locking effect between the worm gear 32 and the worm 33, which can prevent the second spiral spring 38 from causing the positioning block 7 to be retracted into the guide groove 701 again, improving the connection reliability;

[0072] Step b, transmission

[0073] When one rotating tube 3 rotates, the magnetic outer gear ring 20 or the cylindrical gear 18 rotates. Through the meshing between the magnetic outer gear ring 20 and the cylindrical gear 18, the other rotating tube 3 rotates, thereby completing the transmission;

[0074] Step c, Lubrication

[0075] The first pump body 9 pumps the lubricating oil in the oil tank 8 into the fixed short pipe 6 and the rotating pipe 3 successively through the third pipe body 24 and the first pipe body 10, and then enters the inner cavity 1801. At the meshing position of the magnetic external gear ring 20 and the cylindrical gear 18, the magnetic external gear ring 20 magnetically attracts the iron block 28, causing the iron block 28 to move, opening the oil outlet groove 25, and the lubricating oil flows out from the oil outlet groove 25 to lubricate the meshing magnetic external gear ring 20 and cylindrical gear 18; under the blocking action of the blocking seat 40, it is prevented that the iron block 28 falls out of the oil outlet groove 25, and the iron block 28 drives the guide rod 27 to move in the guide hole 26. At the non-meshing position of the magnetic external gear ring 20 and the cylindrical gear 18, the first spiral spring 29 in the compressed state causes the iron block 28 to reset;

[0076] Step d, Recycling

[0077] The lubricating oil flowing out from the oil outlet groove 25, after lubricating the meshing magnetic external gear ring 20 and cylindrical gear 18, flows into the oil receiving hopper 21. Through the suction of the second pump body 23, the lubricating oil in the oil receiving hopper 21 enters the suction pipe 17, flows into the fixed short pipe 6 through the one-way valve 16 or enters the second pipe body 14 through the three-way pipe 15, and returns to the oil tank 8 for recycling;

[0078] Step e, Disassembly

[0079] By reversely screwing the rotating knob 5, the worm 33 rotates reversely. Through the meshing between the worm 33 and the worm gear 32, the rotating rod 31 rotates reversely, and the cam 35 will rotate reversely synchronously. The second spiral spring 38 in the compressed state causes the positioning block 7 to be retracted into the guide groove 701 again, canceling the positioning of the rotating pipe 3 and the external connecting member 39. At this time, the external connecting member 39 is disassembled from the rotating pipe 3.

[0080] It should be noted that the above is only the specific implementation manner of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
