Description

Technical Field

[0001] The utility model relates to the technical field of transmission shafts, in particular to a high-efficiency transmission shaft for a speed reducer. Background Art

[0002] In the mechanical transmission system, the drive shaft of the reducer is one of the most critical components. The drive shaft transfers power from the power source, such as the motor, engine, etc., to other shafts or components inside the reducer, thereby realizing the effective transmission and distribution of power. During the transmission process, the drive shaft realizes its own rotation through the bearing, and drives the load-bearing shaft to rotate with the help of the engagement of the small gear and the large gear, and then, with the support of the bearing, the load-bearing shaft provides power to the external equipment.

[0003] During this connection process, bearing rotation and gear transmission will inevitably cause wear, which has a significant impact on the working efficiency of the transmission shaft. At present, the main method to solve the wear problem is to add a large amount of lubricating oil at one time to reduce the wear. However, when the reducer is in continuous operation, this lubrication method has obvious disadvantages:

[0004] For example, the lubricating oil added once can only provide lubrication for a very short time, which is difficult to meet the needs of long-term operation;

[0005] For another example, the centrifugal force generated when the machine rotates will cause a large amount of liquid lubricating oil to be thrown out, resulting in a large amount of lubricating oil waste.

[0006] In order to solve the above problems, the present application proposes a high-efficiency transmission shaft for a reducer. Utility Model Content

[0007] To solve the above technical problems, the embodiment of the present application provides a high-efficiency transmission shaft for a reducer, comprising a reducer lower chassis, an upper chassis fixedly connected to the reducer lower chassis, and a lubrication assembly movably mounted in the reducer lower chassis and the upper chassis, the lubrication assembly comprising an inlet pipe, a dispersion cylinder, a side outlet pipe, a front outlet pipe, an oil storage tank, a sealing gasket, a connecting rod, and a base plate;

[0008] The inlet pipe is fixedly connected to the lower chassis of the reducer, the inlet pipe is fixedly connected to the dispersion cylinder through the side outlet pipe, the front position of the dispersion cylinder is fixedly connected to the front outlet pipe, the oil storage tank is fixedly connected to the upper chassis, the sealing gasket is fixedly connected in the oil storage tank, the bottom plate is movably installed on the sealing gasket, and the connecting rod is fixedly connected to the bottom plate.

[0009] In some embodiments, bearing grooves are provided on the lower and upper chassis of the reducer, and a transmission shaft and a force-bearing shaft are movably installed in the lower and upper chassis of the reducer. Both sides of the transmission shaft and the force-bearing shaft are movably installed in the bearing grooves through bearings, and large and small gears of different diameters are fixedly connected to the force-bearing shaft and the transmission shaft.

[0010] In some embodiments, the lubrication assembly further includes an inclined hole groove and a plug connector. The inclined hole groove is opened on the lower chassis of the reducer, and the inclined hole groove and the bearing groove are connected to each other. The inlet pipe is fixedly connected in the inclined hole groove, and the outer end position of the side outlet pipe is fixedly connected with a plug connector, and the plug connector is plugged into the upper position of the inlet pipe.

[0011] In some embodiments, the lubrication assembly further includes a sealing ring, which is fixedly connected to the dispersion cylinder and is located between the oil storage tank and the dispersion cylinder.

[0012] In some embodiments, the lubrication assembly further includes a docking joint and an oil dripping hole. The docking joint is fixedly connected to the bottom surface of the oil storage tank. The docking joint is movably installed in the dispersion cylinder and is located in the sealing ring. Oil dripping holes are opened on the bottom surface of the docking joint and the sealing gasket. The sealing gasket is fixedly connected in the docking joint, and the bottom plate is movably installed in the docking joint.

[0013] In some embodiments, the lubrication assembly further includes an upper cover and a rotating shaft. The upper cover is clamped on the oil storage tank and is located on the upper chassis. The connecting rod is movably mounted on the upper cover through the rotating shaft.

[0014] In some embodiments, the lubrication assembly further includes a knob, which is fixedly connected to the upper end of the connecting rod, and a plurality of through holes are provided on the bottom plate.

[0015] The utility model has at least the following beneficial effects:

[0016] Through the provided lubrication component, the knob is turned to select the appropriate position on the bottom plate, so that different numbers of through holes appear in the oil dripping hole, and the speed of the lubricating oil dripping downwards is changed, so that the lubricating oil falls into the dispersion cylinder, and the oil body gathers in the dispersion cylinder. When the liquid level reaches the position of the side outlet pipe and the front outlet pipe, the oil body disperses and flows into the bearing position and the large and small gear transmission positions, lubricating the bearing rotation and gear transmission, reducing wear, and maintaining high working efficiency of the transmission shaft. In addition, by dripping the oil body, the lubricating oil addition process is slower, which effectively extends the lubrication time. At the same time, adding a small amount of lubricating oil makes the amount of lubricating oil on the surface of the mechanical components less, which is convenient for the machine to absorb in time and fully, and avoids throwing out excess or unabsorbed lubricating oil, causing waste.

[0026] 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.

[0027] Example 1:

[0028] See also Figures 1 to 6The utility model provides a technical solution: a high-efficiency transmission shaft for a reducer, comprising a reducer lower chassis 1, an upper chassis 2 fixedly connected to the reducer lower chassis 1, and a lubrication component 3. Bearing grooves 4 are provided on the reducer lower chassis 1 and the upper chassis 2. A transmission shaft 5 and a force-bearing shaft 6 are movably installed in the reducer lower chassis 1 and the upper chassis 2. Both sides of the transmission shaft 5 and the force-bearing shaft 6 are movably installed in the bearing groove 4 through bearings. Large and small gears with different diameters are fixedly connected to the force-bearing shaft 6 and the transmission shaft 5 respectively.

[0029] Furthermore, the lubrication assembly 3 is movably installed in the lower chassis 1 and the upper chassis 2 of the reducer. The lubrication assembly 3 includes an inlet pipe 302, a dispersion cylinder 303, a side outlet pipe 304, a front outlet pipe 306, an oil storage tank 308, a sealing gasket 311, a connecting rod 313 and a bottom plate 314. The inlet pipe 302 is fixedly connected to the lower chassis 1 of the reducer. The inlet pipe 302 is fixedly connected to the dispersion cylinder 303 through the side outlet pipe 304. The front position of the dispersion cylinder 303 is fixedly connected to the front outlet pipe 306. The oil storage tank 308 is fixedly connected to the upper chassis 2. The sealing gasket 311 is fixedly connected to the oil storage tank 308. The bottom plate 314 is movably installed on the sealing gasket 311.

[0030] The dispersion cylinder 303 is located in the area where the small gear is located on the transmission shaft 5. A small gear is provided on the transmission shaft 5, and a large gear is provided on the force-bearing shaft 6. The large gear is driven by the small gear to decelerate. The front outlet pipe 306 and the side outlet pipe 304 in the dispersion cylinder 303 are connected at the same height. The dispersion cylinder 303 is in a horizontal position. When the liquid level in the cylinder rises and exceeds the height of the side outlet pipe 304 and the front outlet pipe 306, the liquid immediately enters the side outlet pipe 304 and the front outlet pipe 306 for dispersion.

[0031] Furthermore, the lubrication assembly 3 further includes an oblique hole groove 301 and a plug connector 307. The oblique hole groove 301 is provided on the reducer lower chassis 1, and the oblique hole groove 301 and the bearing groove 4 are mutually conductive. The introduction pipe 302 is fixedly connected in the oblique hole groove 301. The outer end of the side lead-out pipe 304 is fixedly connected to the plug connector 307, and the plug connector 307 is plugged into the upper position of the introduction pipe 302.

[0032] The inclined hole groove 301 is tilted downward to facilitate the introduction of liquid lubricating oil into the bearing area. The introduction pipe 302 is connected to the introduction pipe 302 through the plug connector 307, making the dispersion cylinder 303, the side lead-out pipe 304 and other structures easy to disassemble and clean.

[0033] Furthermore, the lubrication assembly 3 further includes a sealing ring 305, which is fixedly connected to the dispersion cylinder 303 and is located between the oil storage tank 308 and the dispersion cylinder 303. The lubrication assembly 3 further includes a docking joint 309 and an oil dripping hole 310. The docking joint 309 is fixedly connected to the bottom surface of the oil storage tank 308, and the docking joint 309 is movably installed in the dispersion cylinder 303 and is located in the sealing ring 305. The oil dripping hole 310 is opened on the bottom surface of the docking joint 309 and the sealing gasket 311. The sealing gasket 311 is fixedly connected in the docking joint 309.

[0034] The liquid lubricating oil in the oil storage tank 308 flows downward into the dispersion cylinder 303 through the sealing gasket 311 and the oil dripping hole 310 of the joint 309. The dispersion cylinder 303 is connected to the oil storage tank 308 through the sealing ring 305, so that the oil body is not easy to flow out from between the two, thereby enhancing the sealing performance. When the height of the liquid therein exceeds the height of the connection between the side lead-out pipe 304 and the front lead-out pipe 306, the liquid flows out along the front lead-out pipe 306 and the side lead-out pipe 304. The side lead-out pipe 304 introduces the liquid into the inlet pipe 302, and finally introduces the liquid lubricating oil into the area where the bearing is located through the inclined hole groove 301 to lubricate the bearing. The front lead-out pipe 306 introduces the liquid into the position where the large and small gears are meshed with each other for transmission, thereby lubricating the large and small gears of the transmission, thereby reducing the wear during the rotation of the bearing and the gear. A small amount of addition is made through the oil dripping hole 310 to extend the lubrication time.

[0035] Example 2:

[0036] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 Based on Example 1, the present invention provides another technical solution: the connecting rod 313 is fixedly connected to the bottom plate 314, and the bottom plate 314 is movably installed in the docking joint 309. The lubrication assembly 3 further includes an upper cover 312 and a rotating shaft 316. The upper cover 312 is clamped on the oil storage tank 308 and is located on the upper chassis 2. The connecting rod 313 is movably installed with the upper cover 312 via the rotating shaft 316. The lubrication assembly 3 further includes a knob 315, which is fixedly connected to the upper end of the connecting rod 313. A plurality of through holes are provided on the bottom plate 314.

[0037] The bottom plate 314 is divided into several areas, each of which is provided with different through-holes or no through-holes. Corresponding markings are provided on the knob 315. The bottom plate 314 extends into the docking joint 309, squeezing the sealing gasket 311. The upper cover 312 is snapped into the upper position of the oil reservoir 308. By turning the knob 315, different numbers of through-holes or no through-holes appear in the oil dripping hole 310, and the oil dripping holes 310 of the docking joint 309 and the sealing gasket 311 overlap. In this case, the lubricating oil must first pass through the through-holes in the bottom plate 314 before entering the oil dripping holes 310 of the sealing gasket 311 and the docking joint 309. The different numbers of through-holes further control the dripping speed of the lubricating oil. Therefore, the lubricating oil is slowly introduced into the rotating bearing and gear rotating position through a slow dripping method, thereby achieving a longer effective lubrication time. The slow addition of lubricating oil prevents too much liquid from appearing on the surface of the mechanical components at the same time, avoiding the phenomenon of delayed absorption and excess lubricating oil being thrown away, thereby ensuring more effective lubricating oil utilization.
