Description

Technical Field

[0002] The reducer gearbox is an important device widely used in the field of mechanical transmission. In industrial production, many equipment need to convert the high-speed, low-torque power of the prime mover (such as electric motors, internal combustion engines, etc.) into a low-speed, high-torque output suitable for specific working requirements.

If this heat is not dissipated in time, the temperature inside the box will continue to rise, causing the gears to wear more severely and reduce their service life. Some components will also deform due to heat, affecting their accuracy and normal operation. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figure 1-Figure 4 As shown, this embodiment provides a speed reducer gearbox, including a box body 1. The existing speed reducer gearbox needs power input from the input shaft when in use, and the output shaft rotates through the meshing transmission of gears of different sizes and numbers of teeth. During the rotation process, the friction heat generated by the meshing of the gears causes the connected bearings and other components to heat up. If the heat is not dissipated in time, the temperature inside the box body will continue to rise, causing the gears to wear more and reduce their service life. Some parts will also be deformed due to heat, affecting their accuracy and normal operation. Therefore, a heat dissipation component 2 is provided on the left side of the box body 1. The heat dissipation component 2 is used to reduce the temperature inside the box body 1. A dust cleaning component 3 is provided on the left side of the box body 1. The dust cleaning component 3 is located at the bottom of the heat dissipation component 2 and is used to clean the dust on the surface of the heat dissipation component 2, wherein:

[0024] The heat dissipation component 2 includes a connecting frame 21 fixed to the left inner wall of the box body 1, and a thermally conductive silicone pad 24 is fixedly connected to the inner cavity of the box body 1. A plurality of heat sinks 23 are tightly fitted on the left side of the thermally conductive silicone pad 24. The heat sink 23 is used to absorb the heat on the surface of the thermally conductive silicone pad 24, and the heat generated by the operation of the box body 1 is absorbed by the thermally conductive silicone pad 24. Since the heat sink 23 is connected to the thermally conductive silicone pad 24, the heat sink 23 can absorb the heat of the thermally conductive silicone pad 24 to reduce the temperature inside the box body 1. The device is generally installed in a production workshop with a lot of dust. The cleaning component 3 is arranged at the bottom of the heat sink 23 to clean the surface of the heat sink 23.

[0025] The improvement of this embodiment is that:

[0026] Considering that the existing reducer gearbox needs power to be input from the input shaft when in use, the output shaft rotates through the meshing transmission of gears of different sizes and numbers of teeth. During the rotation process, the friction heat generated by the meshing of the gears causes the connected bearings and other components to heat up. If the heat is not dissipated in time, the temperature inside the box will continue to rise, causing the gears to wear more severely and reduce their service life. Some parts will also be deformed due to heat, affecting their accuracy and normal operation. Therefore, through the close cooperation between the heat sink 23 and the thermal conductive silicone pad 24, the heat can be quickly and evenly dissipated, so that the temperature of each part in the box body 1 remains relatively balanced, avoiding local overheating from causing excessive pressure on specific parts, and further extending the service life of the overall equipment. The cleaning component 3 can clean the dust on the surface of the heat sink 23 in time to ensure that the heat dissipation efficiency of the heat sink 23 will not decrease due to dust accumulation, thereby maintaining good heat dissipation performance for a long time and reducing the maintenance cost and frequency of the equipment.

[0027] In order to arrange the heat sink 23 inside the connecting frame 21, a support frame 22 is fixedly connected to the surface of the heat sink 23, and the upper and lower ends of the support frame 22 are fixedly connected to the inner wall of the connecting frame 21. The surface of the heat sink 23 is located inside the connecting frame 21. The support frame 22 is fixed to the inner wall of the connecting frame 21, so that the heat sink 23 can be located inside the connecting frame 21. At this time, the heat sink 23 can be attached to the left side of the thermal conductive silicone pad 24 to dissipate heat inside the box body 1.

[0028] In order to prevent the heat sink 23 from being installed on the outside of the box body 1 for a long time and having a lot of dust piled on the surface, which will affect the heat dissipation effect of the heat sink 23, the dust cleaning component 3 includes an air suction frame 31 fixedly connected to the left side of the box body 1, and the top of the air suction frame 31 is fixedly connected with an air suction port 32, and the front of the air suction frame 31 is fixedly connected with an air exhaust port 33, and the air suction port 32 is located at the bottom of the heat sink 23. Through the operation of the air suction frame 31, the air circulation at the top of the air suction port 32 can absorb the heat from the surface of the heat sink 23, and the dust on the surface of the heat sink 23 can also be adsorbed into the inside of the air suction frame 31 and discharged from the air exhaust port 33, so as to absorb dust and help the heat sink 23 to reduce the temperature.

[0029] In order to enable the heat dissipation component 2 to absorb the temperature inside the box body 1, an input shaft 111 is extended from the inner cavity of the box body 1 by rotation, a connecting shaft 110 is connected to the inside of the box body 1 by rotation, and an output shaft 11 is extended from the inside of the box body 1 by rotation. The connecting shaft 110 is connected to the input shaft 111 and the output shaft 11 by gear meshing transmission. The input shaft 111, the connecting shaft 110 and the output shaft 11 are close to the left side of the box body 1. The heat dissipation component 2 is arranged on the left side of the box body 1, and can absorb the heat generated when the box body 1 rotates.

[0030] In order to allow the interior of the box body 1 to be repaired when a fault occurs, a maintenance cover 12 is rotatably connected to the top of the box body 1 using a hinge. The maintenance cover 12 is arranged above the input shaft 111. The maintenance cover 12 is pulled to separate it from the box body 1, and the input shaft 111 and the like can then be repaired.

[0031] When the reducer gearbox of the utility model is used, power is transmitted to the input shaft 111, and the output shaft 11 rotates the connecting shaft 110 and the output shaft 11 through the gears on the surface. The output shaft 11 can be transmitted by rotating it, and the heat generated by the input shaft 111 when working can be absorbed by the thermal conductive silicone pad 24 fixed to the inner cavity of the box body 1, and the heat sink 23 attached to the surface of the thermal conductive silicone pad 24 can be used to conduct heat out, and the air circulation at the top of the suction port 32 can absorb the heat on the surface of the heat sink 23 through the operation of the suction frame 31, and the dust on the surface of the heat sink 23 can also be adsorbed into the suction frame 31 and discharged from the exhaust port 33, so as to absorb dust and help the heat sink 23 to reduce the temperature.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
