Description

Technical Field

[0001] This utility model relates to the field of speed reducer cooling technology, specifically to a speed reducer cooling device. Background Technology

[0002] Nowadays, industrial development has become a top priority, resulting in a wide variety of mechanical equipment. Mechanical equipment is an indispensable part of industrial development. When a machine is in operation, some components or the main body of the device can perform different mechanical movements to achieve various purposes according to the needs of the operator. The speed reducer is one of many mechanical devices, and the speed reducer generates a lot of heat during operation. If the heat is not dissipated in time, it will affect the operation of the speed reducer.

[0003] According to application number 202420028768.9, a cooling device for a cable car reducer includes a reducer body and a pump body. The pump body is installed on the outside of the reducer body to provide pumping power for the oil. An oil delivery pipe is installed on the outside of the reducer body and is connected to the pump body to deliver the oil in the reducer body. A cooling pipe is connected above the oil delivery pipe and a return oil pipe is connected below the cooling pipe. The return oil pipe is connected to the reducer body so that the oil in the oil delivery pipe is cooled by the cooling pipe and then circulates into the interior of the reducer body. The cable crane reducer cooling device uses an oil supply pipe and a return pipe in conjunction with a pump to extract and circulate the oil from the reducer body. During oil extraction, cooling blades cool the oil, allowing for rapid heat dissipation from the reducer's internal structure—a more efficient method than surface cooling. However, the cooling blades are still driven by a drive mechanism to rotate during oil supply, meaning the cooling fan power cannot be adjusted based on the internal heat level. This results in significant energy consumption and waste, increasing the reducer's cooling cost. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for a speed reducer, comprising a speed reducer body, a base plate fixedly connected to the upper surface of the speed reducer body, and a cooling assembly mounted on the upper surface of the base plate. A mounting seat is provided on one side of the base plate, and a heating tube is fixedly connected to the lower end of the mounting seat.

One end of the liquid outlet pipe is fixedly connected to the reducer body. The upper end of the circulation pump is fixedly connected to a conveying pipe, and one end of the conveying pipe is fixedly connected to a cooling pipe. One end of the cooling pipe is fixedly connected to the upper surface of the reducer body, and the side surface of the cooling pipe is provided with a heat dissipation mechanism.

[0007] Preferably, the heat dissipation mechanism includes a heat dissipation shroud, which is fitted onto the side surface of the cooling pipe, and multiple heat dissipation plates are fixedly connected to the side surface of the heat dissipation shroud.

[0008] Preferably, the cooling assembly includes a support frame, and a rotating shaft is rotatably connected inside the support frame. A cooling fan blade is fixedly connected to one side surface of the rotating shaft, and a drive plate is fixedly connected to the other end of the rotating shaft. The drive plate is hinged to one side surface of the drive rod.

[0009] Preferably, the reset mechanism includes a support plate, which is fixedly connected to the side surface of the positioning tube. A movable plate is hinged to one end of the support plate, and a push rod is hinged to one end of the movable plate. One end of the push rod is hinged to the upper end of the drive rod.

[0010] Preferably, a push plate is hinged to the other end of the movable plate, and a piston I is hinged to one end of the push plate. A sleeve is slidably connected to the side surface of the piston I, and one end of the sleeve is fixedly connected to the side surface of the mounting base.

[0011] This invention provides a cooling device for a speed reducer. Compared with the prior art, it has the following advantages:

[0012] The drive plate, which is fixedly connected to one end of the shaft, and the piston II, which is connected to one side of the drive plate via a drive rod, cooperate with the heating tube, the mounting base, and the reset mechanism on one side of the drive rod. This avoids the need to consume electrical energy to cool the reducer, thus preventing the consumption of a large amount of electrical energy and avoiding the waste of electrical energy, while also reducing the cooling cost of the reducer.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a cooling device for a speed reducer, including a speed reducer body 1, a base plate 101 fixedly connected to the upper surface of the speed reducer body 1, a cooling component installed on the upper surface of the base plate 101, a mounting seat 301 provided on one side of the base plate 101, a heating pipe 3 fixedly connected to the lower end of the mounting seat 301, the heating pipe 3 being located inside the speed reducer body 1, a positioning pipe 302 fixedly connected to the upper end of the mounting seat 301, the heating pipe 3, the mounting seat 301 and the positioning pipe 302 being connected in communication, a piston II 3010 slidably connected inside the positioning pipe 302, a drive rod 303 hinged to the upper surface of the piston II 3010, the upper end of the drive rod 303 being connected to the cooling component, a reset mechanism provided on one side of the drive rod 303, and a circulation mechanism provided at the other end of the speed reducer body 1.

[0020] As a technical optimization of this utility model, the circulation mechanism includes a circulation pump 204, one end of which is fixedly connected to an outlet pipe 205, and one end of the outlet pipe 205 is fixedly connected to the reducer body 1. The upper end of the circulation pump 204 is fixedly connected to a conveying pipe 203, one end of which is fixedly connected to a cooling pipe 2, and one end of the cooling pipe 2 is fixedly connected to the upper surface of the reducer body 1. The side surface of the cooling pipe 2 is provided with a heat dissipation mechanism. The coolant inside the reducer body 1 can be circulated and conveyed through the circulation pump 204, the conveying pipe 203 and the outlet pipe 205.

[0021] As a technical optimization of this utility model, the heat dissipation mechanism includes a heat dissipation cover 201, which is sleeved on the side surface of the cooling pipe 2. Multiple sets of heat dissipation plates 202 are fixedly connected to the side surface of the heat dissipation cover 201. The heat dissipation cover 201 and the heat dissipation plates 202 can quickly absorb the temperature of the coolant inside the cooling pipe 2. The heat dissipation mechanism blows away the heat of the heat dissipation plates 202, thereby cooling the coolant.

[0022] As a technical optimization of this utility model, the cooling assembly includes a support frame 102, a rotating shaft 105 is rotatably connected inside the support frame 102, a cooling fan blade 104 is fixedly connected to one side surface of the rotating shaft 105, and a drive plate 103 is fixedly connected to the other end of the rotating shaft 105. The drive plate 103 is hinged to one side surface of the drive rod 303. The cooling assembly can cool the coolant inside the cooling pipe 2 and cool the reducer body 1 after the coolant flows into the reducer body 1.

[0023] As a technical optimization of this utility model, the reset mechanism includes a support plate 305, which is fixedly connected to the side surface of the positioning tube 302. One end of the support plate 305 is hinged to a movable plate 306, and one end of the movable plate 306 is hinged to a push rod 304. One end of the push rod 304 is hinged to the upper end of the drive rod 303, and the other end of the movable plate 306 is hinged to a push plate 307. One end of the push plate 307 is hinged to a piston I 308, and a sleeve 309 is slidably connected to the side surface of the piston I 308. One end of the sleeve 309 is fixedly connected to the side surface of the mounting base 301, and the sleeve 309 communicates with the mounting base 301. Through the cooperation of the piston I 308, the sleeve 309, the support plate 305, the movable plate 306, the push rod 304, and the push plate 307 in the reset mechanism, the piston II 3010 can be pushed to reset, compressing the gas inside the heating tube 3, so that the piston II 3010 reciprocates.

[0024] In use, the operator starts the reducer body 1 normally. After a period of use, the coolant inside the reducer body 1 will be heated. At this time, the operator starts the circulation pump 204. The circulation pump 204 will circulate the coolant inside the reducer body 1 through the delivery pipe 203. Simultaneously, the heating pipe 3 inside the reducer body 1 will be heated. The air inside the heating pipe 3 will push the piston II 3010 inside the positioning pipe 302, and at the same time, it will also push the piston I 308 inside the sleeve 309 to move. When piston II 3010 moves upward via drive rod 303, piston I 308 pushes push rod 304 to deflect via movable plate 306 and push rod 304, thereby driving drive plate 103 to rotate. At this time, drive plate 103 drives shaft 105 to rotate, thus shaft 105 drives cooling fan blade 104 to rotate, thereby cooling the heat sink 201 and heat sink 202 on the side surface of cooling pipe 2. At this time, heat sink 201 and heat sink 202 will carry away the temperature cooled inside cooling pipe 2, and then the coolant returns to the inside of reducer body 1 to cool reducer body 1.
