Description

TECHNICAL FIELD

[0001] The utility model relates to a reduction gear technology field, concretely is a reduction gear with auxiliary air cooling structure. BACKGROUND

[0002] The reduction gear is a kind of independent component by gear drive, worm drive, gear-worm drive enclosed in rigid shell, commonly used as the speed reduction transmission device between prime mover and working machine. Between prime mover and working machine or actuator, it plays the role of matching speed and transmitting torque, and is widely used in modern machinery.

[0003] According to the reduction gear with the protection structure (announcement number: CN212985969U) disclosed, in the above application, the once heat dissipation effect is realized by being provided with the slot type heat dissipation structure, then, by being provided with the protection structure, the protection of overall structure is safer.

[0004] But the above-mentioned equipment in actual use process, the reduction gear relies on the heat dissipation slot set in the inside, increases the effective heat dissipation contact area between reduction gear and external environment, but such heat dissipation mode is relatively passive, and the common way of adding air cooling mechanism to reduction gear will face the problem that when external environment is relatively humid, humid air will enter the inside of reduction gear and condensate in the inside of reduction gear, so that the gear in the inside of reduction gear is prone to rust and damage. In view of this, we provide a reduction gear with auxiliary air cooling structure. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a reduction gear with auxiliary air cooling structure to solve the problems in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical scheme: a reduction gear with auxiliary air cooling structure, including machine body, the top of machine body is fixedly installed with fan, the bottom of machine body is provided with air inlet slot, the bottom center of air inlet slot is provided with air inlet, the inside of air inlet is provided with air guide assembly;

[0007] Among them, the air guide assembly includes inclined plate, the inclined plate is fixedly installed on the inner wall of air inlet, the inner wall of air inlet is fixedly installed with triangular belt, the both ends surface of triangular belt is fixedly installed with arc-shaped band, the inner wall of arc-shaped band is provided with leak hole, the upper surface of arc-shaped band is provided with arc-shaped groove, the left and right side inclined wall of triangular belt is provided with inclined hole.

[0008] Preferably, the air inlet slot is arranged in the shape of "X", and the air inlet is arranged at the intersection of the "X" shape.

[0009] Preferably, there are two sets of inclined plates, and the two sets of inclined plates are arranged in a mirror image on the left and right sides of the vertical central axis of the air inlet. The top of the inclined plate is inclined towards the center of the air inlet and the bottom is inclined away from the center of the air inlet.

[0010] Preferably, the triangular belt is disposed between the two sets of inclined plates, and the top of the triangular belt is disposed inside the air inlet on the side close to the center of the machine body, so that the airflow entering the air inlet can be guided by the triangular belt to flow to the left and right sides inside the air inlet, thereby preventing the airflow inside the air inlet from directly entering the machine body upward.

[0011] Preferably, the number of the arc-shaped belts is set in two sets, and the two sets of arc-shaped belts are mirror images of each other at the bottom edges of the left and right sides of the triangular belt. The end of the arc-shaped belt away from the triangular belt is inclined towards the inner wall of the machine body to guide the airflow at the edge of the triangular belt upward.

[0012] Preferably, the arc-shaped groove is shallow near both ends of the triangular belt and deep at the center of the triangular belt, so that the condensed water droplets that fall onto the outer surface of the triangular belt and slide down onto the arc-shaped belt can flow towards the center of the arc-shaped groove under the action of gravity and be discharged through the drain hole.

[0013] Preferably, the top inner wall of the inclined hole is horizontal, and the bottom inner surface of the inclined hole is inclined with a lower slope on the side closer to the center of the V-belt, so that the airflow entering the bottom center of the V-belt can be guided by the inclined hole to blow horizontally toward the surface of the inclined plate.

[0014] Compared with the prior art, this utility model provides a speed reducer with an auxiliary air-cooling structure, which has the following beneficial effects:

[0015] 1. This reducer with an auxiliary air-cooling structure is equipped with an air guide assembly. In conjunction with the V-belt, arc belt, and inclined plate, the air inlet is divided into four air intake channels. The V-belt obstructs the airflow entering the machine body through the air inlet, preventing it from entering directly. Instead, the airflow is guided by the V-belt and arc belt to contact the surface of the inclined plate. This allows the moisture in the air to condense into water droplets upon cooling and adhere to the inclined lower surface of the inclined plate. This eliminates the need for a separate drying structure, maintaining good dryness of the air entering the machine body for heat dissipation and preventing humid air from directly entering the machine body and causing rust and damage to the mechanical equipment.

[0016] 2. This reducer with an auxiliary air-cooling structure has oblique holes on the inner wall of the V-belt. The bottom inner surface of the oblique holes is set at a lower angle near the center of the V-belt. This allows the airflow entering the center of the bottom of the V-belt to be guided by the oblique holes and blown horizontally towards the surface of the inclined plate. This not only slows down the airflow between the inclined plate and the V-belt, but also ensures the amount of airflow entering the air inlet. This further increases the movement distance of the airflow in the air inlet, increases the condensation time of the airflow, reduces the humidity in the air, and prevents it from directly affecting the continuous and stable operation of the internal equipment.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a reducer with an auxiliary air-cooling structure, including a body 1, a fan 2 fixedly installed on the top of the body 1, an air inlet groove 3 opened at the bottom of the body 1, an air inlet 4 opened at the center of the bottom of the air inlet groove 3, and an air guide assembly 5 arranged inside the air inlet 4. The air guide assembly 5 includes an inclined plate 51, a triangular belt 52, an arc-shaped belt 53, a drain hole 54, an arc-shaped groove 55, and an inclined hole 56.

[0024] In one embodiment of this utility model, the inclined plate 51 is fixedly installed on the inner wall of the air inlet 4, the inner wall of the air inlet 4 is fixedly installed with a triangular belt 52, the two ends of the triangular belt 52 are fixedly installed with an arc-shaped belt 53, the inner wall of the arc-shaped belt 53 is provided with a leakage hole 54, the upper surface of the arc-shaped belt 53 is provided with an arc-shaped groove 55, and the left and right inclined walls of the triangular belt 52 are provided with inclined holes 56.

[0025] Furthermore, the fan 2 is located directly above the body 1, and the fan 2 is connected to the internal cavity of the body 1. At the same time, the air inlet slot 3 is arranged in a "+" shape, and the air inlet 4 is located at the intersection of the "+" shape of the air inlet slot 3. Specifically, the ends of the air inlet slot 3 are connected to the side of the body 1 to ensure that there is sufficient air intake in the air inlet 4 when the fan 2 is started, so that the body 1 can generate an upward airflow to carry away the heat generated by the gear transmission inside the body 1, thereby cooling the reducer and maintaining its high stability of operation.

[0026] Meanwhile, two sets of inclined plates 51 are provided, and the two sets of inclined plates 51 are mirror images of each other on the left and right sides of the vertical central axis of the air inlet 4. The top of the inclined plates 51 is inclined towards the center of the air inlet 4, and the bottom is inclined away from the center of the air inlet 4. Specifically, a triangular belt 52 is provided between the two sets of inclined plates 51, and the top of the triangular belt 52 is positioned inside the air inlet 4 near the center of the body 1. This allows the airflow entering the air inlet 4 to be guided by the triangular belt 52 to flow towards the left and right sides inside the air inlet 4, avoiding... The airflow in the air inlet 4 enters the body 1 directly upwards. Furthermore, there are two sets of arc-shaped belts 53, and the two sets of arc-shaped belts 53 are mirror images of each other at the bottom edges of the left and right sides of the triangular belt 52. The ends of the arc-shaped belts 53 away from the triangular belt 52 are inclined towards the inner wall of the body 1 to guide the airflow at the edge of the triangular belt 52 upwards, so that it enters the gap between the triangular belt 52 and the inclined plate 51. Specifically, the inclined plate 51 can also effectively make the condensed liquid droplets drip downwards to the outside of the body 1.

[0027] In addition, there are multiple sets of leakage holes 54, and these multiple sets of leakage holes 54 are evenly distributed in a linear array on the inner wall of the arc-shaped belt 53. The arc-shaped groove 55 is shallow near both ends of the triangular belt 52 and deep at the center of the triangular belt 52. This allows the condensed water droplets that fall onto the outer surface of the triangular belt 52 and slide down onto the arc-shaped belt 53 to flow towards the center of the arc-shaped groove 55 under the action of gravity and be discharged through the leakage holes 54. This prevents water from accumulating at the air inlet 4 and affecting the subsequent drying air intake inside the machine body 1.

[0028] Meanwhile, the top inner wall of the inclined hole 56 is set to be horizontal, and the bottom inner surface of the inclined hole 56 is set to be lower on the side closer to the center of the V-belt 52, so that the airflow entering the bottom center of the V-belt 52 can be guided by the inclined hole 56 to blow horizontally towards the surface of the inclined plate 51. This not only slows down the airflow between the inclined plate 51 and the V-belt 52, but also ensures the amount of airflow entering the air inlet 4, further increasing the movement distance of the airflow in the air inlet 4, increasing the condensation time of the airflow, reducing the humidity in the air, and preventing it from directly affecting the continuous and stable operation of the internal equipment of the machine body 1.

[0029] In this invention, during use, the fan 2 is started simultaneously, allowing air from the external environment to enter the interior of the machine body 1 through the air inlet slot 3 and air inlet 4, and finally discharged outwards through the fan 2, thereby removing heat from the interior of the machine body 1 and achieving a cooling effect. At the same time, by setting up the air guide component 5, in conjunction with the triangular belt 52, the arc belt 53 and the inclined plate 51, the air inlet 4 is divided into four air intake channels. Furthermore, the triangular belt 52 blocks the airflow entering the machine body 1 through the air inlet 4, preventing it from entering directly. Instead, the airflow is affected by the triangular belt 52 and the arc belt 53 and comes into contact with the surface of the inclined plate 51. This allows the moisture in the air to condense into water droplets upon cooling and adhere to the inclined lower surface of the inclined plate 51. Without the need for a separate drying structure, the air entering the machine body 1 for heat dissipation can be kept dry, preventing humid air from directly entering the machine body 1 and causing rust and damage to the mechanical equipment.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
