[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention provides a lubricated reducer. When the telescopic cylinder is in the extended state, the first gear block meshes with the inner side of the helical gear, and the second meshing gear meshes with the second meshing disc. At this time, the locking block leaves the locking groove, and the two sets of insert rods are inserted between the three sets of L-shaped rods to limit their movement. The input shaft drives the input transmission shaft to rotate, causing the helical gear to rotate and drive the second rotating shaft and the first rotating shaft. The first rotating shaft ultimately drives the first helical gear to rotate. When the first helical gear rotates, it drives the second helical gear and the gear ring to rotate. When the second helical gear rotates, it drives the output transmission shaft and the output shaft to rotate through the second meshing disc and the second meshing gear to achieve speed reduction. When it is necessary to reduce the speed and increase the torque, The retraction of the telescopic cylinder causes the locking block to insert into the locking groove to limit the gear ring. The two sets of insert rods disengage from the L-shaped rods. At this time, the first meshing gear meshes with the first meshing disc, and the output drive shaft meshes with the second fixed disc through the second tooth block. When the input shaft rotates, it drives the second helical gear to rotate through the input drive shaft, the first meshing gear, and the first meshing disc. When the second helical gear rotates, since the gear ring does not rotate, the first helical gear revolves around the second helical gear while rotating on its own axis. When the first helical gear revolves, the three sets of L-shaped rods drive the second fixed disc to rotate, which in turn drives the output shaft to rotate slowly through the output drive shaft, thus achieving the function of changing the transmission speed. The operation is simple.
[0017] 2. The present invention provides a lubricated reducer, in which lubricating fluid is delivered from the housing into the interior of a three-way pipe through a fluid delivery mechanism. When the input shaft rotates, the driven disc is driven to rotate through the driving disc and the second transmission belt. The driven disc drives the first transmission disc and the second transmission disc to rotate through spur gears. When the first transmission disc and the second transmission disc rotate, the lubricating fluid enters the connecting pipe through the three-way pipe and the bend pipe, and is finally sprayed out through the flow equalization plate and the nozzle. With the rotation of the first transmission disc and the second transmission disc, the spraying is more uniform, the lubrication effect is better, and the difference in the degree of wear of the gears is avoided.
[0018] 3. The present invention provides a lubricated reducer in which the output shaft drives the cam to rotate when it rotates. When the cam rotates, it drives the movable rod to reciprocate through the limiting groove. When the movable rod reciprocates, it causes the two sets of piston plates inside the piston cylinder to move closer or further apart. When the piston plates move further apart, the lubricating oil inside the housing is drawn into the temporal part of the piston cylinder through the inlet pipe under the action of the first one-way valve. When the piston plates move closer together, the oil is pumped into the interior of the three-way pipe under the action of the second one-way valve and the first one-way valve, reducing oil contamination. Once the equipment starts running, it can perform oil pumping for cooling and lubrication. Attached Figure Description

The other end of the second rotating shaft 2251 extends into the interior of the first fixed disk 226 and is fixedly connected to an end face gear 2252 that meshes with the helical gear 2261. An input drive shaft is movably disposed inside the first fixed disk 226. 227, and the input drive shaft 227 passes through the helical gear 2261. The input drive shaft 227 has a first tooth block 2271 evenly distributed on it. The inner side of the helical gear 2261 is provided with a groove corresponding to the first tooth block 2271. The end of the input drive shaft 227 near the second helical gear 216 is fixedly connected to the first meshing gear 2281. The outer side of the second helical gear 216 is fixedly connected to the first meshing disk 228 corresponding to the first meshing gear 2281. The side of the housing 1 is rotatably connected to the input shaft 229, and the input shaft 229 is slidably connected to the input drive shaft 227. The engagement assembly 23 includes a telescopic cylinder 231 fixedly connected to the inner wall of the housing 1. A square frame 232 is fixedly connected to the output end of the telescopic cylinder 231, and the input drive shaft 227 is rotatably connected to the square frame 232. A locking block 233 is fixedly connected to the inner side of the square frame 232, and the locking block 233 corresponds to the locking groove 213. A plug rod 234 is also fixedly connected to the square frame 232.
[0023] The output assembly 24 includes a second fixed ring 241 fixedly connected to the other side of the first helical gear 214. A second bearing 242 is fixedly connected to the inner side of the second fixed ring 241. An L-shaped rod 243 is fixedly connected to the inner side of the second bearing 242. The other ends of the three sets of L-shaped rods 243 are fixedly connected to a second fixed disk 244. An output drive shaft 246 is movably arranged in the middle of the second fixed disk 244, and the output drive shaft 246 is rotatably connected to the square frame 232.
[0024] On the outer wall of the output drive shaft 246, second tooth blocks 2462 are evenly distributed between the second fixed disk 244 and the second helical gear 216, and the interior of the second fixed disk 244 is provided with grooves corresponding to the second tooth blocks 2462. A second meshing gear 2461 is fixedly connected to one end of the output drive shaft 246 near the second helical gear 216. A second meshing disk 245 corresponding to the second meshing gear 2461 is fixedly connected to the other outer wall of the second helical gear 216. An output shaft 247 is rotatably connected to the other side of the housing 1, and the output shaft 247 is slidably connected to the output drive shaft 246. Telescopic cylinder 23... When 1 is in the extended state, the first tooth block 2271 meshes with the inner side of the helical gear 2261, and the second meshing gear 2461 meshes with the second meshing disc 245. At this time, the locking block 233 leaves the locking groove 213, and the two sets of insert rods 234 are inserted between the three sets of L-shaped rods 243 to limit them. The telescopic cylinder 231 retracts, causing the locking block 233 to insert into the locking groove 213 to limit the gear ring 212. The two sets of insert rods 234 leave the L-shaped rods 243. At this time, the first meshing gear 2281 meshes with the first meshing disc 228, and the output drive shaft 246 meshes with the second fixed disc 244 through the second tooth block 2462.
[0025] Specifically, when the telescopic cylinder 231 is in the extended state, the first tooth block 2271 meshes with the inner side of the helical gear 2261, and the second meshing gear 2461 meshes with the second meshing disc 245. At this time, the locking block 233 leaves the locking groove 213, and the two sets of insert rods 234 are inserted between the three sets of L-shaped rods 243 to limit them. The input shaft 229 drives the input transmission shaft 227 to rotate, causing the helical gear 2261 to rotate and drive the second rotating shaft 2251 and the first rotating shaft 2231. The first rotating shaft 2231 ultimately drives the first helical gear 214 to rotate. When the first helical gear 214 rotates, it drives the second helical gear 216 and the gear ring 212 to rotate. When the second helical gear 216 rotates, it drives the output transmission shaft 246 and the output shaft 247 to rotate through the second meshing disc 245 and the second meshing gear 2461 to achieve deceleration. When it is necessary to reduce the speed and increase the torque, the speed is reduced by... The retraction of the telescopic cylinder 231 causes the locking block 233 to insert into the locking groove 213 to limit the gear ring 212. The two sets of insert rods 234 disengage from the L-shaped rod 243. At this time, the first meshing gear 2281 meshes with the first meshing disc 228, and the output transmission shaft 246 meshes with the second fixed disc 244 through the second tooth block 2462. When the input shaft 229 rotates, it drives the second helical gear 216 to rotate through the input transmission shaft 227, the first meshing gear 2281, and the first meshing disc 228. When the second helical gear 216 rotates, since the gear ring 212 does not rotate, the first helical gear 214 revolves around the second helical gear 216 while rotating on its own axis. When the first helical gear 214 revolves, the three sets of L-shaped rods 243 drive the second fixed disc 244 to rotate, which in turn drives the output shaft 247 to rotate slowly through the output transmission shaft 246, thus achieving the effect of changing the transmission speed.
[0026] To address the technical problem of uneven wear on planetary gears due to some gears being located in the upper part of the housing, thus affecting service life, the following measures were taken: Figures 9-11 As shown, the following preferred technical solutions are provided: The lubrication mechanism 3 includes a transmission assembly 31 and a liquid dispensing assembly 32. The transmission assembly 31 includes a triangular frame 311 fixedly connected inside the housing 1. A first transmission disk 312 is rotatably connected to the upper part of the interior of the triangular frame 311, and a second transmission disk 313 is rotatably connected to both sides of the lower part of the interior of the triangular frame 311.
[0027] A first transmission belt 314 is fitted between the first transmission disc 312 and the two sets of second transmission discs 313. The transmission assembly 31 also includes a drive disc 315 fixedly connected to the input shaft 229. A driven disc 317 is rotatably connected to the inner wall of the front end of the housing 1 via a shaft. A second transmission belt 316 is installed between the driven disc 317 and the drive disc 315. A spur gear 318 is fixedly connected to the rear of the driven disc 317, and the spur gear 318 meshes with the outer wall of the first transmission disc 312. When the input shaft 229 rotates, the drive disc 315 drives the second transmission belt 316 to rotate, which in turn drives the driven disc 317 to rotate. The driven disc 317 drives the first transmission disc 312 to rotate via the spur gear 318, which in turn drives the two sets of second transmission discs 313 to rotate via the first transmission belt 314.
[0028] The liquid dispensing assembly 32 includes a three-way pipe 321 disposed inside the front of the housing 1. The other end of the three-way pipe 321 is fixedly connected to a bend pipe 322. The inner wall of the bend pipe 322 is rotatably connected to a connecting pipe 324 through a sealed bearing 323. The three sets of connecting pipes 324 are respectively fixedly connected to the first transmission disc 312 and the two sets of second transmission discs 313.
[0029] The connecting pipe 324 passes through the first transmission disc 312 and the second transmission disc 313 and is fixedly connected to the flow equalization plate 325. The nozzles 326 are distributed on the other side of the flow equalization plate 325. The first transmission disc 312 and the second transmission disc 313 rotate, which drives the connecting pipe 324, the flow equalization plate 325 and the nozzles 326 to rotate.
[0030] Specifically, the lubricating fluid in the housing 1 is delivered into the interior of the three-way pipe 321 through the infusion mechanism 4. When the input shaft 229 rotates, the driven disc 317 is driven to rotate through the active disc 315 and the second transmission belt 316. The driven disc 317 drives the first transmission disc 312 and the second transmission disc 313 to rotate through the spur gear 318. When the first transmission disc 312 and the second transmission disc 313 rotate, the lubricating fluid enters the connecting pipe 324 through the three-way pipe 321 and the bend pipe 322, and is finally sprayed out through the flow equalization plate 325 and the nozzle 326. Under the rotation of the first transmission disc 312 and the second transmission disc 313, the spraying is more uniform.
[0031] To address the technical problem of needing a separate oil pump to deliver lubricating oil during the lubrication process, and the potential for oil sludge in the lubricating oil to clog the pump, such as... Figures 12-15 As shown, the following preferred technical solutions are provided: The infusion mechanism 4 includes a linkage component 41 and an infusion component 42.

A square hole 4121 is provided on the limiting shaft 412, and the limiting shaft 412 is slidably connected to the square rod 4132 through the square hole 4121. A second sliding groove 4133 is provided below the movable rod 413. The output shaft 247 drives the cam 411 to rotate, causing the movable rod 413 to swing back and forth through the movement inside the limiting groove 4111.
[0033] The infusion assembly 42 includes a piston cylinder 423 fixedly connected to the lower part of the housing 1. Piston plates 422 are slidably connected to both sides of the piston cylinder 423.

An outlet pipe 426 is fixedly connected to the side of the piston cylinder 423. The other end of the outlet pipe 426 is connected to the three-way pipe 321. A second one-way valve 427 is provided on the outlet pipe 426. When the movable rod 413 swings back and forth, the two sets of piston plates 422 move or move away from each other inside the piston cylinder 423, ultimately delivering the coolant inside the housing 1 into the three-way pipe 321 and spraying it out through the nozzle 326 to achieve lubrication.
[0034] Specifically, when the output shaft 247 rotates, it drives the cam 411 to rotate. When the cam 411 rotates, it drives the movable rod 413 to reciprocate through the limiting groove 4111. When the movable rod 413 reciprocates, it causes the two sets of piston plates 422 inside the piston cylinder 423 to move closer or further apart. When the piston plates 422 move further apart, under the action of the first one-way valve 425, the lubricating oil inside the housing 1 is drawn into the temporal part of the piston cylinder 423 through the liquid inlet pipe 424. When the piston plates 422 move closer together, under the action of the second one-way valve 427 and the first one-way valve 425, the oil is pumped into the interior of the three-way pipe 321 to reduce oil contamination. Once the equipment starts running, it can perform oil pumping for cooling and lubrication.
