Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, and specifically relates to a highly waterproof rotary speed reducer. Background Technology

[0002] A highly waterproof rotary reducer is a transmission device specifically designed for humid environments, primarily used in applications requiring low-speed, high-torque output and demanding high waterproof performance. Existing highly waterproof rotary reducers mainly employ multi-layer sealing designs, such as O-rings, lip seals, or labyrinth seals, installed at the joints of the input shaft, output shaft, and housing, effectively preventing moisture infiltration. The advantage of this approach is that the multi-layer sealing design significantly enhances the reducer's waterproof capability. In particular, structures like O-rings, lip seals, and labyrinth seals effectively prevent moisture from seeping into the interior from the joints of the input shaft, output shaft, and housing, ensuring normal operation in humid or underwater environments. However, its disadvantage is that while the multi-layer sealing design effectively prevents moisture ingress, the seals (such as O-rings and lip seals) will age and fail over long-term use due to wear or environmental factors (such as high temperature and chemical corrosion), thus reducing waterproof performance. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a highly waterproof rotary reducer to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a highly waterproof rotary reducer, comprising: a waterproof housing body, wherein a side plate one and a side plate two are respectively installed on the front and back of the waterproof housing body, and a waterproof groove is provided on the top of the waterproof housing body;

[0005] The bottom of the first side plate is glued with a sealing gasket, and the front of the first side plate is threaded with two waterproof caps. The back of the waterproof caps is glued with a sealing ring. The back of the second side plate is provided with several sets of air inlets, and a waterproof cover is welded to the outside of each set of air inlets.

[0006] In a preferred embodiment, a reducer body is installed inside the waterproof housing body. The reducer body is mounted on the top of the base plate below it by four sets of bolts. Mounting holes are provided at the four corners of the top of the base plate.

[0007] In a preferred embodiment, the bottom of the waterproof housing body is provided with four sets of fixing plates. The four sets of fixing plates are respectively connected and fixed to the mounting holes by a bolt. The shape of the waterproof housing body matches the shape of the reducer body. After the waterproof housing body is installed and fixed to the base plate, the sealing gasket is tightly squeezed on the bottom of the waterproof housing body and the top of the base plate, thereby waterproofing and sealing the gap between the waterproof housing body and the base plate.

[0008] In a preferred embodiment, a heat-conducting substrate is installed on the front side wall inside the reducer body, and a heat-conducting pad is installed on the front side of the reducer body in the area opposite to the heat-conducting substrate. Several sets of heat dissipation fins are installed on the front side of the heat-conducting pad.

[0009] In a preferred embodiment, the first side plate is fixed to the front of the waterproof outer shell body by four sets of screws, and the joint between the first side plate and the waterproof outer shell body is provided with sealant. The second side plate is installed in the same way as the first side plate.

[0010] In a preferred embodiment, two sets of mounting bases are installed on one front side of the side panel. The mounting bases are recessed to the rear to form mounting grooves. Negative pressure fans are installed inside the mounting grooves, and threads are provided on the outside of the mounting grooves. Air is introduced into the waterproof housing body through the two sets of negative pressure fans, thereby absorbing the heat from the surface of several sets of heat dissipation fins through the external air and finally expelling it from the outside of the waterproof housing body, thereby achieving the effect of heat dissipation and preventing overheating inside the waterproof housing body.

[0011] In a preferred embodiment, the inner side of the back of the waterproof cover is provided with an internal thread groove that matches the thread specification, and the front of the waterproof cover is provided with a waterproof mesh.

[0012] In a preferred embodiment, the waterproof cover is an arc-shaped structure tilted downwards at 60 degrees. The waterproof cover is welded to the outer edge of the air inlet, and a waterproof mesh is glued to the air inlet.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up a waterproof outer shell main body, side plate one, and side plate two, a waterproof groove is opened on the top of the waterproof outer shell main body. When water droplets fall on the top of the waterproof cover, they will gather inside the waterproof groove and be discharged downward along the left and right sides of the waterproof groove, thereby achieving a waterproof effect. A sealing gasket is glued to the bottom of the waterproof outer shell main body. When the waterproof outer shell main body is installed and fixed with the base plate, the sealing gasket is tightly squeezed between the bottom of the waterproof outer shell main body and the top of the base plate, thereby sealing the gap at the connection between the waterproof outer shell main body and the base plate. The connection between side plate one and the waterproof outer shell main body is provided with sealant, and the connection method of side plate two and side plate one is the same. A waterproof cover inclined downward at 60 degrees is welded to the outside of the air inlet hole opened on the back of side plate two, so as to prevent water droplets from entering the interior of the waterproof outer shell main body through the air inlet hole. Therefore, the waterproof outer shell main body, side plate one, and side plate two can waterproof the reducer body in all directions, significantly improving the waterproof effect of the reducer body.

[0014] 2. By setting heat dissipation fins and air inlets, the heat inside the reducer body is transferred to the gap between the waterproof housing body and the reducer body through the heat-conducting substrate, heat-conducting pad, and several sets of heat dissipation fins. Two sets of negative pressure fans introduce external air into the gap between the waterproof housing body and the reducer body through the air inlets. The air circulates between the several sets of heat dissipation fins, thereby achieving the effect of heat dissipation for the reducer body and preventing poor heat dissipation inside the waterproof housing body, which would affect its normal operation.

[0022] 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 one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4 A highly waterproof rotary reducer includes: a waterproof housing body 200, with a side plate 210 and a side plate 220 respectively installed on the front and back of the waterproof housing body 200, and a waterproof groove 201 opened on the top of the waterproof housing body 200.

[0024] Side panel 210 has a sealing gasket 214 glued to the bottom. Side panel 210 has two waterproof caps 212 threaded on the front. The waterproof caps 212 have a sealing ring 213 glued to the back. Side panel 220 has several sets of air inlets on the back. Each set of air inlets has a waterproof cover 221 welded to the outside.

[0025] The waterproof outer shell 200 houses the reducer body 100, which is mounted on the top of the base plate below it by four sets of bolts. Mounting holes are provided at the four corners of the top of the base plate.

[0026] The bottom of the waterproof housing body 200 is provided with four sets of fixing plates. Each of the four sets of fixing plates is connected and fixed to the mounting holes by a bolt. The shape of the waterproof housing body 200 matches the shape of the reducer body 100. After the waterproof housing body 200 is installed and fixed to the base plate, the sealing gasket 214 is tightly pressed on the bottom of the waterproof housing body 200 and the top of the base plate, thereby waterproofing and sealing the gap between the waterproof housing body 200 and the base plate.

[0027] A heat-conducting substrate is installed on the front side wall inside the reducer body 100. A heat-conducting pad is installed on the front of the reducer body 100 in the area opposite to the heat-conducting substrate. Several sets of heat dissipation fins 110 are installed on the front of the heat-conducting pad.

[0028] Side panel 210 is fixed to the front of the waterproof housing body 200 by four sets of screws, and sealant is provided at the joint between side panel 210 and the waterproof housing body 200. The installation method between side panel 220 and the waterproof housing body 200 is the same as that of side panel 210.

[0029] Two sets of mounting bases are installed on the front of the side panel 210. The front of the mounting base is recessed to form a mounting groove. A negative pressure fan 211 is installed inside the mounting groove. The outside of the mounting groove is threaded. The two sets of negative pressure fans 211 introduce air into the waterproof housing body 200. The heat on the surface of several sets of heat dissipation fins 110 is absorbed by the external air and finally discharged to the outside of the waterproof housing body 200, thereby achieving the effect of heat dissipation and preventing the inside of the waterproof housing body 200 from overheating.

[0030] The waterproof cover 212 has an inner thread groove on the back side that matches the thread specification, and a waterproof mesh is provided on the front side of the waterproof cover 212.

[0031] The waterproof cover 221 is an arc-shaped structure tilted downward at 60 degrees. The waterproof cover 221 is welded to the outer edge of the air inlet, and a waterproof mesh is glued to the air inlet.

[0032] Example 1: Please refer to Figures 1 to 4 In actual use, the accelerator body is installed on the base plate below it by four sets of bolts. The base plate has mounting holes at the four corners of the top. The bottom of the waterproof outer shell 200 has four fixing plates, which are connected and fixed to the mounting holes by bolts. A sealing gasket 214 is glued to the bottom of the waterproof outer shell 200. After the waterproof outer shell 200 is installed and fixed to the base plate, the sealing gasket 214 is tightly squeezed between the waterproof outer shell 200 and the base plate, thereby sealing the connection between the waterproof outer shell 200 and the base plate and preventing water droplets from entering. A waterproof groove 201 is opened on the top of the waterproof outer shell 200. When water droplets fall from above, they are collected by the waterproof groove 201 and discharged from the left and right sides of the waterproof groove 201, thereby achieving a waterproof effect.

[0033] Side plate 1 210 and side plate 220 are respectively installed on the front and back of the waterproof housing body 200 by screws. The connection between side plate 1 210 and side plate 220 and the waterproof housing body 200 is sealed with sealant. Side plate 1 210 has two mounting bases on its front. Negative pressure fan 211 is installed inside the mounting base. A waterproof cover 212 is provided on the front of the mounting base. A waterproof mesh 1 is glued to the front of the waterproof cover 212 to prevent water droplets from entering the interior of the waterproof cover 212. The waterproof cover 212 is connected to the mounting base by threads. After the threaded connection is completed, the sealing ring 213 glued to the back of the waterproof cover 212 will be tightly squeezed between the back of the waterproof cover 212 and the front of side plate 1 210, thus preventing water from entering. Side plate 220 has several sets of air inlets on its back for the negative pressure fan 211 to introduce outside air into the interior of the waterproof housing body 200. A waterproof mesh 2 is glued to the inside of the air inlets to prevent water from entering the interior of the waterproof housing body 200 through the air inlets.

[0034] A waterproof cover 221 is welded to the outer edge of the air intake. The waterproof cover 221 is an arc-shaped structure that tilts downward at a 60-degree angle. When water droplets fall downward, they can be blocked by the waterproof cover 221 to prevent water droplets from entering the air intake. Since the waterproof housing body 200, side plate one 210 and side plate two 220 are all independently installed on the outside of the reducer body 100, they are easy to disassemble. Even if the sealing gasket 214 and sealing ring 213 age due to environmental factors, they can be quickly replaced. Therefore, the final effect is that the waterproof housing body 200, side plate one 210 and side plate two 220 can provide all-round waterproofing for the reducer body 100, which significantly improves the waterproof effect of the reducer body 100.

[0035] Example 2: Please refer to Figures 1 to 4 A heat-conducting substrate is installed on the front side wall inside the reducer body 100, and a heat-conducting pad is installed in the area opposite to the front of the reducer body 100 and the heat-conducting substrate. Several sets of heat dissipation fins 110 are provided on the front of the heat-conducting pad. Through the heat-conducting substrate, the heat-conducting pad and the several sets of heat dissipation fins 110, the heat inside the reducer body 100 can be guided to the area between the waterproof housing body 200 and the reducer body 100. At this time, two sets of negative pressure fans 211 can be started. After the negative pressure fans 211 are working, they introduce external air into the waterproof housing body 200 from the air inlet. After the air enters, it absorbs the heat on the surface of the heat dissipation fins 110 and then exhausts it through the two sets of negative pressure fans 211, thereby achieving the effect of heat dissipation.

[0036] It should be noted that when the reducer body 100 operates in a humid environment, the air will inevitably contain some moisture. This moisture enters the waterproof housing 200 through the air inlet and participates in heat dissipation. Large water droplets in the environment will be intercepted by the waterproof cover 221 and the waterproof mesh inside the air inlet, allowing the moisture-containing air to enter. The reducer body 100 itself has a certain sealing performance, so the moisture in the air is negligible. The final effect is to dissipate heat inside the waterproof housing 200, preventing poor heat dissipation after the reducer body 100 is installed inside the waterproof housing 200, which would affect its normal performance.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
