Technical Field
[0001] The utility model relates to the technical field of speed reducers, and particularly relates to a speed reducer heat dissipation box body. Background Art
[0002] A speed reducer plays a role in matching speeds and transmitting torques between a prime mover and a working machine or an actuator, and is widely used in modern machinery. The speed reducer can be divided into two categories: general-purpose speed reducers and special-purpose speed reducers according to their uses. The design, manufacture, and use characteristics of the two are different. A speed reducer is an independent closed transmission device between a prime mover and a working machine, used to reduce speed and increase torque to meet the working requirements. In some cases, it is also used to increase speed, called a speed increaser. When selecting a speed reducer, factors such as the selection conditions of the working machine, technical parameters, performance of the prime mover, and economy should be considered. Compare the outer dimensions, transmission efficiency, load-bearing capacity, quality, price, etc. of different types and varieties of speed reducers to select the most suitable speed reducer. A speed reducer is a relatively precise machine, and the purpose of using it is to reduce speed and increase torque.
[0003] At present, during the long-term operation of a speed reducer, its internal components are prone to heat generation. The existing box bodies of speed reducers dissipate heat by setting a number of heat dissipation grooves. However, when the box body does not need to dissipate heat, dust easily enters its interior through the heat dissipation grooves, thus affecting the use effect of the speed reducer. Therefore, it is urgent to design a speed reducer heat dissipation box body that can block the heat dissipation grooves to solve the above problems. Summary of the Utility Model

There is a notch 4 between the two first grooves 2, and rotating shafts 5 are provided on both. Through holes 7 are opened on their side walls. One end of each of the two rotating shafts 5 is fixed with a first bevel gear 6, and the other ends are respectively fixed with a first transmission wheel 10 and a second transmission wheel 11. A round rod 8 is movably connected in the through hole 7. One end of the round rod 8 is located on the side of the box body 1 and fixed with a round plate 31, and the other end is located in the first groove 2 and fixed with a second bevel gear 9 that meshes and drives with the first bevel gear 6. A number of baffle plates 21 are fixed on the side of the round plate 31 for blocking a number of strip-shaped heat dissipation grooves 3; A driving motor 12 is also installed on the bottom end face of the box body 1. Its output end extends into the notch 4 and is connected with a third transmission wheel 13. The third transmission wheel 13 is connected with the first transmission wheel 10 and the second transmission wheel 11 through a first conveyor belt 15 and a second conveyor belt 14 respectively. By driving the third transmission wheel 13 to rotate through the output end of the driving motor 12, the third transmission wheel 13 drives the first transmission wheel 10 and the second transmission wheel 11 to rotate through the first conveyor belt 15 and the second conveyor belt 14 respectively. At this time, both rotating shafts drive the first bevel gear 6 to mesh and drive with the second bevel gear 9. Finally, both round plates 31 drive a number of baffle plates 21 to rotate to block a number of strip-shaped heat dissipation grooves 3, preventing external dust from entering the box body 1 when heat dissipation is not required. Using a speed reducer heat dissipation box body, a number of baffle plates 21 are provided to dissipate heat from a number of strip-shaped heat dissipation grooves 3, preventing dust from entering the box body 1 and thus affecting the use effect of the speed reducer. The design is reasonable and easy to promote.
[0021] Furthermore, the side wall of the first groove 2 is also connected with a ring 17 through a connecting rod 16. The ring 17 is slidably connected with the rotating shaft 5, and an annular chute 18 is opened on its inner wall. A sliding ring 19 located in the annular chute 18 is also fixed on the rotating shaft 5 for supporting the rotation of the rotating shaft 5 and ensuring that the first bevel gear 6 always meshes and drives with the second bevel gear 9.
[0022] Furthermore, a number of baffle plates 21 are uniformly distributed and have the same number as the strip-shaped heat dissipation grooves 3, so that the baffle plates can correspond to the strip-shaped heat dissipation grooves 3 one by one to block them, preventing external dust from entering the box body 1 when heat dissipation is not required and thus affecting the use effect of the speed reducer.
[0023] Furthermore, a box cover 28 is provided at the top of the box body 1, and clamping grooves 20 are opened on both inner walls. Its structural cross-section is as Figure 4As shown in the figure, straight groove openings 22 are provided at both ends of the top surface of the box cover 28.

Oblique clamping blocks 26 located in the clamping grooves 20 are fixed to the outer sides of their bottoms. Under the elastic action of the two springs 25, both slide plates 24 drive the oblique clamping blocks 26 to enter the clamping grooves 20, thus completing the installation of the box cover 28. When disassembly is required, the two handles 27 are moved inwards so that both slide plates 24 move inwards. At this time, both oblique clamping blocks 26 disengage from the clamping grooves 20, and finally the box cover 28 is removed to complete its disassembly.
[0024] Furthermore, columns 30 are fixed at the four corners of the bottom end of the box body main body 1 to support the box body main body 1 so as to have sufficient space to install the drive motor 12.
[0025] Furthermore, two handles 29 are fixed on the box cover 28 to facilitate the movement of the box cover 28.
[0026] The working principle of the present utility model is as follows: First, the drive motor 12 is started, and its output end drives the third transmission wheel 13 to rotate, so that the third transmission wheel 13 drives the first transmission wheel 10 and the second transmission wheel 11 to rotate through the first conveyor belt 15 and the second conveyor belt 14 respectively. At this time, both rotating shafts drive the first bevel gear 6 to mesh and drive with the second bevel gear 9, and both circular plates 31 drive a plurality of baffle plates 21 to rotate to correspondingly block a plurality of strip-shaped heat dissipation grooves 3 one by one, preventing external dust from entering the box body main body 1 when heat dissipation is not required, thus affecting the use effect of the speed reducer.
