A high-torque speed reducer

Abstract

The present invention relates to the technical field of speed reducers, and specifically relates to a high-torque speed reducer, which mainly includes a speed reducer main body. A heat sink is fixedly installed on the top surface of the speed reducer main body. It also includes: a blowing mechanism, which is arranged above the speed reducer main body. The blowing mechanism includes an air outlet pipe located above the heat sink, and a moving plate is arranged above the air outlet pipe. A cooling mechanism is arranged on one side of the air outlet pipe. When the moving plate drives the fixed block and the push rod to move, the push rod drives the piston plate to reciprocate in the fixed box. Thus, after the fixed box sucks cooling water from the water tank through the connecting pipe, it sprays from the nozzle to the speed reducer main body and the heat sink through the second hose and the water spray pipe. Therefore, the speed reducer main body is cooled by the cooling water. In an environment with a relatively high temperature, the cooling water can still effectively cool the speed reducer main body, ensuring that the temperature of the speed reducer main body is not too high and damaged, and improving the service life.

Description

Technical Field

[0001] The present invention relates to the technical field of speed reducers, and specifically to a high-torque speed reducer. Background Art

[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or actuator.

[0003] Chinese Patent Publication No. CN221401577U discloses a high-torque speed reducer. By setting up a bracket, the speed reducer is placed inside the bracket, and a lead screw and a slide bar are arranged on the bracket to enable it to move up and down, so that its fixing method has diversification and it can be suspended and fixed. By arranging a dust-proof device above the heat dissipation mechanism, the structure is simple and the use is convenient. The dust-proof filter screen can, to a certain extent, prevent dust from falling on the heat dissipation mechanism and affecting the heat dissipation performance, thereby improving the working efficiency and service life of the device.

[0004] However, when this device is in use, the speed reducer body is cooled by a fan and heat sinks. In a high-temperature environment, it is difficult to quickly and effectively cool down the speed reducer body only by the fan blowing air to take away the heat on the speed reducer body. After long-term use, it is easy to cause damage to the speed reducer body and reduce its service life. Summary of the Invention

[0020] When the moving plate drives the fixed block and the push rod to move in the present invention, the push rod drives the piston plate to reciprocate in the fixed box. Thus, after the fixed box sucks cooling water from the water tank through the communicating pipe, it sprays from the spray head to the reducer main body and the heat sink through the hose two and the water spray pipe. Thus, the reducer main body is cooled by the cooling water. In an environment with a relatively high temperature, the cooling water can still effectively cool the reducer main body, ensuring that the temperature of the reducer main body is not too high and damaged, and improving the service life.

[0021] By setting the motor to drive the rotating shaft and the fan blades to rotate, the wind generated by the rotation of the fan blades is conveyed from the fixed box to the air outlet pipe through the hose one, and then blows from the air outlet head to the heat sink and the reducer main body. At the same time, the rotating shaft drives the fixed strip and the cylinder to rotate. The cylinder slides in the through groove and drives the moving plate to reciprocate. The moving plate drives the fixed column and the moving frame to reciprocate through the two inclined grooves. The moving frame drives the air outlet pipe and the air outlet head to reciprocate. Thus, the air outlet head blows and cools the reducer main body and the heat sink comprehensively, blowing away the heat on the reducer main body. Thus, the reducer main body is effectively cooled by heat dissipation, and the service life is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In this embodiment: Through the provided filter plate 203, the air entering the interior of the fixed box 202 is filtered to prevent sundries from entering the fixed box 202 and causing blockage. The provided motor 204 drives the rotating shaft 205 and the fan blade 206 to rotate, and the fan blade 206 generates wind power.

[0040] Specifically, as Figures 1 - 8 shown, two T-shaped grooves 207 are respectively opened on the bottom surfaces of the two support frames 201. A plurality of T-shaped blocks 208 are respectively slidably installed on the inner walls of the plurality of T-shaped grooves 207. Two moving frames 209 are fixedly installed on the bottom surfaces of the plurality of T-shaped blocks 208. There are two air outlet pipes 210.

[0041] In this embodiment: The T-shaped groove 207 is provided to limit the T-shaped block 208, thereby limiting the moving frame 209 and the air outlet pipe 210, so that the moving frame 209 drives the air outlet pipe 210 to move more smoothly.

[0042] Specifically, as Figures 1 - 8 shown, one ends of the two air outlet pipes 210 respectively fixedly penetrate through the sides of the two moving frames 209 and extend to the other side of the moving frames 209. Flexible hoses 212 are respectively fixedly installed at the air inlets of the two air outlet pipes 210. The other ends of the two flexible hoses 212 respectively fixedly penetrate through the bottom surface of the fixed box 202 and extend into the interior of the fixed box 202.

[0043] In this embodiment: Through the provided flexible hose 212, the air outlet pipe 210 can move freely without being affected.

[0044] Specifically, as Figures 1 - 8 shown, two limiting rods 213 are fixedly installed on the mutually adjacent sides of the two support frames 201. Limiting holes are penetratingly opened on the side surface of the moving plate 214. The outer walls of the two limiting rods 213 are respectively slidably connected to the inner walls of the two limiting holes.

[0045] In this embodiment: The moving plate 214 is limited by the provided limiting rod 213, and the provided inclined groove 215 drives the internal fixed column 216 to move, thereby driving the moving frame 209 to move.

[0046] Specifically, as Figures 1 - 8 shown, the lower end of the rotating shaft 205 rotates through the inner wall of the lower end of the fixed box 202 and extends below the fixed box 202. A fixed strip 217 is fixedly installed on the outer wall of the lower end of the rotating shaft 205, and a cylinder 218 is fixedly installed on the bottom surface of the other end of the fixed strip 217. A through groove 219 is formed through the top surface of the moving plate 214, and the outer wall of the cylinder 218 is slidably connected to the inner wall of the through groove 219.

[0047] In this embodiment: The provided rotating shaft 205 drives the fixed strip 217 to rotate, and the fixed strip 217 drives the cylinder 218 to rotate on the inner wall of the through groove 219, thereby driving the moving plate 214 to reciprocate.

[0048] Cooling mechanism 3, the cooling mechanism 3 is arranged on one side of the air outlet pipe 210. The cooling mechanism 3 includes a water spray pipe 310 located on one side of the air outlet pipe 210. A fixed box 304 is arranged above the water spray pipe 310. A piston plate 306 is slidably installed on the inner wall of the fixed box 304. The cooling mechanism 3 is used to spray water to cool the main body of the reducer 1.

[0049] Specifically, as Figures 1 - 8 shown, support bars 301 are respectively fixedly installed on both sides of the fixed box 202. Two water tanks 302 are respectively fixedly installed on the top surfaces of the plurality of support bars 301. Water filling ports 303 are respectively arranged on the top surfaces of the two water tanks 302. Connecting pipes 305 are respectively fixedly installed through the side surfaces of the two water tanks 302 in a penetrating manner.

[0050] In this embodiment: The provided water tank 302 is used to hold cooling water and provide cooling water for the device.

[0051] Specifically, as Figures 1 - 8 shown, there are two fixed boxes 304 and two piston plates 306. The bottom surfaces of the two fixed boxes 304 are fixedly connected to the top surface of the support frame 201 on one side. The other ends of the two connecting pipes 305 respectively penetrate through the top surfaces of the two fixed boxes 304 and extend into the fixed boxes 304. One-way valves I are respectively fixedly installed on the two connecting pipes 305.

[0052] In this embodiment: Through the provided fixed box 304 and piston plate 306, the piston plate 306 slides on the inner wall of the fixed box 304, thereby sucking cooling water from the water tank 302 into the fixed box 304 through the connecting pipe 305. The provided one-way valve I can only suck cooling water from the fixed box 304 and cannot transport it in the reverse direction.

[0053] Specifically, as Figures 1 - 8As shown in the figure, push rods 307 are respectively and fixedly installed on the sides of the two piston plates 306. The other ends of the two push rods 307 respectively slide through the inner wall of one side of the fixed box 304 and extend to the outside of the fixed box 304. Fixed blocks 308 are respectively fixedly installed at the other ends of the two push rods 307. The bottom surfaces of the two fixed blocks 308 are fixedly connected to the top surface of the moving plate 214.

[0054] In this embodiment: By providing the fixed blocks 308, when the moving plate 214 moves, the piston plates 306 are driven to move through the fixed blocks 308 and the push rods 307, so as to suck and discharge the cooling water.

[0055] Specifically, as Figures 1 - 8 shown in the figure, there are two water spray pipes 310. A plurality of spray nozzles 311 are respectively and fixedly installed through the outer walls of the lower ends of the two water spray pipes 310. Two fixing sleeves 309 are respectively fixedly installed on the outer walls of the two water spray pipes 310. The sides of the plurality of fixing sleeves 309 are respectively fixedly connected to the sides of the two moving frames 209. The water inlet ends of the two water spray pipes 310 are installed with a second one-way valve and a second hose 312. The other ends of the two second hoses 312 respectively fixedly penetrate through the sides of the two fixed boxes 304 and extend into the fixed boxes 304.

[0056] In this embodiment: By providing the water spray pipes 310 and the spray nozzles 311, the cooling water is sprayed onto the main body 1 of the speed reducer and the heat sink 101, so as to effectively cool the main body 1 of the speed reducer. The second one-way valve is provided to make the fixed box 304 only discharge the cooling water from the second hose 312 and cannot suck the gas and the cooling water.

[0057] The specific solution of this scheme is as follows: Start the motor 204 to drive the rotating shaft 205 and the fan blade 206 to rotate. The wind generated by the rotation of the fan blade 206 is transported from the fixed box 202 to the air outlet pipe 210 through the first hose 212, and then blown from the air outlet head 211 to the heat sink 101 and the main body of the speed reducer 1. At the same time, the rotating shaft 205 drives the fixed strip 217 and the cylinder 218 to rotate. The cylinder 218 slides in the through groove 219 and drives the moving plate 214 to reciprocate. The moving plate 214 drives the fixed column 216 and the moving frame 209 to reciprocate through two inclined grooves 215. The moving frame 209 drives the air outlet pipe 210 and the air outlet head 211 to reciprocate. Thus, the air outlet head 211 blows air comprehensively to cool the main body of the speed reducer 1 and the heat sink 101, and blows away the heat on the main body of the speed reducer 1, thereby effectively cooling the main body of the speed reducer 1, improving its service life. At the same time, the moving frame 209 drives the water spray pipe 310 and the nozzle 311 to reciprocate. When the moving plate 214 reciprocates, it drives the fixed block 308 and the push rod 307 to move. The push rod 307 drives the piston plate 306 to reciprocate in the fixed box 304. Thus, after the fixed box 304 sucks cooling water from the water tank 302 through the connecting pipe 305, it sprays the cooling water from the nozzle 311 to the main body of the speed reducer 1 and the heat sink 101 through the second hose 312 and the water spray pipe 310. Thus, the main body of the speed reducer 1 is cooled by the cooling water. In an environment with a relatively high temperature, the cooling water can still effectively cool the main body of the speed reducer 1, ensuring that the temperature of the main body of the speed reducer 1 does not become too high and get damaged, and improving its service life.

[0059] The present invention aims to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
