Description

Technical Field

[0001] The utility model relates to the technical field of reducers, and in particular to a reducer with convenient heat dissipation. Background Art

[0002] The reducer is an independent component consisting of a gear drive, a worm drive, or a gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. The reducer plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is a relatively precise machine and is widely used in modern machinery.

[0003] A large amount of lubricating oil is added to the reducer chassis to reduce the friction resistance between the gear contact surfaces. The reducer generates heat when it is working. The longer it operates, the more heat it generates. The existing reducer has poor heat dissipation performance and cannot quickly dissipate heat inside the chassis. In the long run, it will cause the gears to be damaged, which will affect the service life of the reducer. Utility Model Content

[0004] The purpose of the utility model is to provide a speed reducer which is convenient for heat dissipation, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reducer with convenient heat dissipation, comprising a base plate and a chassis fixedly arranged above the base plate, characterized in that a heat dissipation assembly is provided on the base plate, and the heat dissipation assembly comprises an extension plate fixedly arranged on the right side of the base plate, a fan fixedly arranged above the extension plate, a heat conducting rod, a heat dissipation rod fixedly arranged on the right side of the heat conducting rod, and a connecting assembly, wherein the heat conducting rod is fixedly connected to the chassis through the connecting assembly, the heat conducting rod is located inside the chassis, the heat dissipation rod is located outside the chassis, a plurality of heat dissipation fins located directly below the fan are fixedly arranged on the heat dissipation rod, and a ventilation slot located directly below the heat dissipation fin is opened on the extension plate.

[0006] Preferably, the connecting assembly includes a sealing sleeve mounted on the heat conducting rod, a sealing disk fixedly arranged on the right side of the sealing sleeve, and a fixing disk fixedly arranged on the heat conducting rod. A socket is provided on the right side wall of the chassis, the sealing sleeve is located inside the socket and is abutted against the chassis, the sealing disk is located on the right side of the chassis, the fixing disk is located on the right side of the sealing disk, and the fixing disk is fixedly connected to the chassis.

[0007] Preferably, the left end of the sealing sleeve is located inside the chassis, and the connecting assembly further comprises a cable tie located inside the chassis, and the sealing sleeve is fixedly connected to the heat conducting rod via the cable tie.

[0008] Preferably, the heat dissipation assembly further comprises a plurality of elastic disks, a plurality of heat dissipation holes are formed on the top wall of the chassis, the elastic disks are fixedly arranged inside the heat dissipation holes, and a cross groove is formed on the elastic disks.

Since the heat conducting rod is located inside the chassis, and the heat dissipating rod is located outside the chassis, the heat conducting rod is fixedly connected to the heat dissipating rod. According to the principle of heat conduction, the lubricating oil will transfer the heat to the heat conducting rod, and the heat conducting rod will transfer the heat to the heat dissipating rod. Since the heat dissipating rod is fixedly provided with a plurality of heat dissipating fins located directly under the fan, the heat conducting rod will disperse the heat to the heat dissipating fins. By starting the fan to blow air to the heat dissipating fins and the heat dissipating rod to dissipate heat, the temperature of the heat dissipating rod can be quickly reduced. The heat dissipating rod and the heat conducting rod are thermally connected. Exchange can reduce the temperature of the heat conducting rod, and heat exchange between the heat conducting rod and the lubricating oil can reduce the temperature of the lubricating oil, which plays a role in facilitating heat dissipation; since the extension plate is provided with a ventilation slot located directly below the heat sink, the air circulation is accelerated; when the temperature inside the chassis rises, the air pressure will also rise. When the air pressure rises to a certain level, the hot air inside the chassis will lift up the elastic disk and be discharged outward through the cross groove, which plays a role in further heat dissipation; in summary, the utility model has the beneficial effect of facilitating heat dissipation, and solves the problem that the existing reducer has poor heat dissipation performance and cannot quickly dissipate the heat inside the chassis. In the long run, the gears are damaged, which affects the service life of the reducer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-3 As shown, the utility model discloses a reducer with convenient heat dissipation, including a base plate 1, a chassis 2 fixedly arranged above the base plate 1, a heat dissipation component is provided on the base plate 1, and the heat dissipation component includes an extension plate 3 fixedly arranged on the right side of the base plate 1, a fan 4 fixedly arranged above the extension plate 3, a heat conducting rod 5, a heat dissipation rod 6 fixedly arranged on the right side of the heat conducting rod 5, and a connecting component, the heat conducting rod 5 is fixedly connected to the chassis 2 through the connecting component, the heat conducting rod 5 is located inside the chassis 2, the heat dissipation rod 6 is located outside the chassis 2, a plurality of heat dissipation fins 7 located directly below the fan 4 are fixedly arranged on the heat dissipation rod 6, and a ventilation slot 8 located directly below the heat dissipation fin 7 is opened on the extension plate 3. When the utility model is used, the lubricating oil is poured into the inside of the chassis 2 so that the lubricating oil covers the heat conducting rod 5. When the reducer works for a long time, the temperature inside the chassis 2 will rise, and the temperature of the lubricating oil will also rise accordingly. Since the heat conducting rod 5 is located inside the chassis 2, and the heat dissipating rod 6 is located outside the chassis 2, the heat conducting rod 5 is fixedly connected to the heat dissipating rod 6. According to the principle of heat conduction, the lubricating oil will transfer the heat to the heat conducting rod 5, and the heat conducting rod 5 will transfer the heat to the heat dissipating rod 6. Since the heat dissipating rod 6 is fixedly provided with a plurality of heat dissipating fins 7 located directly below the fan 4, the heat conducting rod 5 will disperse the heat to the heat dissipating fins 7. When the fan 4 is started to blow air to the heat dissipating fins 7 and the heat dissipating rod 6 to dissipate heat, the temperature of the heat dissipating rod 6 can be quickly reduced, and the heat dissipating rod 6 and the heat conducting rod 5 are thermally exchanged. The heat transfer rod 5 can be exchanged to reduce the temperature of the heat transfer rod 5, and the heat transfer rod 5 can exchange heat with the lubricating oil to reduce the temperature of the lubricating oil, which plays a role in facilitating heat dissipation; since the extension plate 3 is provided with a ventilation slot 8 located directly below the heat sink 7, it plays a role in accelerating air circulation; when the temperature inside the chassis 2 increases, the air pressure will also increase. When the air pressure increases to a certain level, the hot air inside the chassis 2 will lift the elastic disk 14 and be discharged outward through the cross slot 16, which plays a role in further heat dissipation; in summary, the utility model has the beneficial effect of facilitating heat dissipation, and solves the problem that the existing reducer has poor heat dissipation performance and cannot quickly dissipate the heat inside the chassis 2. In the long run, the gears are damaged, which affects the service life of the reducer.

[0019] Preferably, the connection assembly includes a sealing sleeve 9 sleeved on the heat-conducting rod 5, a sealing disk 10 fixedly arranged on the right side of the sealing sleeve 9, and a fixed disk 11 fixedly arranged on the heat-conducting rod 5. A plug hole 12 is provided on the right side wall of the chassis 2. The sealing sleeve 9 is located inside the plug hole 12 and is in contact with the chassis 2. The sealing disk 10 is located on the right side of the chassis 2. The fixed disk 11 is located on the right side of the sealing disk 10. The fixed disk 11 is fixedly connected to the chassis 2. Since the sealing sleeve 9 is sleeved on the heat-conducting rod 5, the sealing sleeve 9 is located inside the plug hole 12 and is in contact with the chassis 2, which plays a sealing role; since the sealing disk 10 is located on the right side of the chassis 2, the fixed disk 11 is located on the right side of the sealing disk 10, and the fixed disk 11 is fixedly connected to the chassis 2, the fixed disk 11 will press the sealing disk 10 between the chassis 2 and the fixed disk 11, which plays a role in preventing the sealing sleeve 9 from sliding.

Since the sealing sleeve 9 is fixedly connected to the heat conducting rod 5 via the cable tie 13, it prevents the lubricating oil from leaking from the connection between the heat conducting rod 5 and the sealing sleeve 9, and further enhances the sealing performance.

[0021] Preferably, the heat dissipation assembly further includes a plurality of elastic disks 14, a plurality of heat dissipation holes 15 are formed on the top wall of the chassis 2, the elastic disks 14 are fixedly arranged inside the heat dissipation holes 15, and a cross groove 16 is formed on the elastic disks 14. Since the elastic disks 14 are fixedly arranged inside the heat dissipation holes 15, and the cross groove 16 is formed on the elastic disks 14, the air pressure will also increase when the temperature inside the chassis 2 increases. When the air pressure increases to a certain level, the hot air inside the chassis 2 will lift up the elastic disks 14 and be discharged outward through the cross groove 16, thereby further dissipating the heat.

[0022] Preferably, an elastic pad 17 is fixedly arranged below the bottom plate 1, and a mounting plate 18 is fixedly arranged below the elastic pad 17. Since the elastic pad 17 is fixedly arranged below the bottom plate 1, a buffering and shock absorbing effect is played.

[0023] Preferably, an observation window 19 is provided on the top wall of the chassis 2, and a transparent plate 20 is fixedly arranged inside the observation window 19. Since the transparent plate 20 is fixedly arranged inside the observation window 19, it is convenient to observe the oil amount inside the reducer and to replenish the oil in time.

[0024] Preferably, a plurality of heat conducting sheets 21 are fixedly arranged on the heat conducting rod 5, and the heat conducting rod 5, the heat dissipating rod 6, the heat dissipating sheet 7 and the heat conducting sheet 21 are all made of copper. Since a plurality of heat conducting sheets 21 are fixedly arranged on the heat conducting rod 5, the heat is quickly absorbed; since the heat conducting rod 5, the heat dissipating rod 6, the heat dissipating sheet 7 and the heat conducting sheet 21 are all made of copper, they have excellent thermal conductivity.
