A speed reducer with a dustproof structure

Abstract

This utility model discloses a speed reducer with a dustproof structure, including a body and a vent integrated on one side of the body. An expansion seat, fixedly connected to the body, is integrated on the outer side of the vent. A splicing seat is fixedly connected to the outer wall of the expansion seat. A strip-shaped groove is formed on the side of the splicing seat away from the expansion seat. A driving component is fixedly connected to the outer wall of the splicing seat. In this application, the driving component drives a transmission rod to rotate. The transmission rod provides traction force to the screw sleeve and the sealing strip through screwing with the screw sleeve. The sealing strip slides along the smooth rod through a sliding sleeve at the bottom, gradually aligning with the corresponding strip-shaped groove until the groove is completely closed. This ensures stable heat dissipation of the body while allowing adjustment of the opening size of the strip-shaped groove according to usage requirements, or even direct closure of the groove to ensure dustproof performance when the speed reducer is not in use, thereby effectively improving the stability of the speed reducer.

Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer with a dustproof structure. Background Technology

[0002] A speed reducer is a power transmission mechanism that uses the speed conversion function of gears to reduce the speed of a motor while increasing the output torque. Its working principle is based on the meshing between a small gear on the input shaft and a large gear on the output shaft, thereby achieving the reduction of speed and the increase of torque.

[0003] Chinese Patent Publication No. CN221723375U, published on 20240917, discloses a turbine reducer with a dustproof structure, including a reduction gearbox. A dustproof mechanism is provided on the outside of the reduction gearbox. The dustproof mechanism includes a mounting plate. L-shaped plates are fixedly connected to the upper and lower parts of the outer side of the mounting plate. A connecting rod is slidably connected through the middle rear side of each L-shaped plate. Anti-detachment plates are fixedly connected to the ends of the two sets of connecting rods that are far apart from each other. Springs are fixedly connected to the outer periphery of the side wall of the two sets of anti-detachment plates that are close to each other. The other ends of the springs are fixedly connected to the side wall of the two sets of L-shaped plates that are far apart from each other.

[0004] Existing speed reducers, such as those mentioned above, often integrate heat dissipation windows and cooling fans on the machine body. In actual implementation, when the speed reducer is not in use, external dust can easily enter the machine body through the heat dissipation windows. As the amount of dust increases, it will affect the normal use of the speed reducer. Therefore, it is urgent to propose a speed reducer with a corresponding dustproof structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a speed reducer with a dustproof structure in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A speed reducer with a dustproof structure includes a body and a vent integrated on one side of the body. An expansion seat fixedly connected to the body is integrated on the outer side of the vent. A splicing seat is fixedly connected to the outer wall of the expansion seat. A strip-shaped groove is formed on the side of the splicing seat away from the expansion seat. A driving component is fixedly connected to the outer wall of the splicing seat. A sealing strip and a pushing component for horizontally pushing the sealing strip are integrated between the output end of the driving component and the interior of the splicing seat.

[0008] Preferably, the outer wall of the splicing base is fixedly connected with an insert, and the insert is detachably connected to the outer wall of the expansion base.

[0009] Preferably, the outer side of the insert is fitted with a retaining sleeve that is fixedly connected to the outer wall of the expansion seat, and a locking rod is screwed onto the inner wall of the retaining sleeve, with the open end of the locking rod abutting against the outer wall of the insert.

[0010] Preferably, the pushing assembly includes a transmission rod and a limiting part for limiting the axial position of the seal. The transmission rod is fixedly connected to the output end of the driving component, and a screw seat that is fixedly connected to the outer wall of the seal is screwed onto the outer wall of the transmission rod.

[0011] Preferably, the limiting part includes a smooth rod and a sliding sleeve that are fixedly connected to the inner wall of the splicing seat and the bottom of the seal respectively, and the inner wall of the sliding sleeve is slidably connected to the outer wall of the smooth rod.

[0012] Preferably, an elastic pad is fixedly connected to the front end face of the seal.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the driving component drives the transmission rod to rotate. The transmission rod provides traction force to the screw sleeve and the sealing strip by screwing with the screw sleeve. The sealing strip slides along the smooth rod through the bottom sliding sleeve. The sealing strip gradually overlaps with the corresponding strip groove until the strip groove is completely closed. This ensures that the heat dissipation process of the machine body is stable. At the same time, the opening size of the strip groove can be adjusted according to the usage requirements, or even the strip groove can be directly closed to ensure the dustproof effect when the reducer is not in use, thereby effectively improving the stability of the reducer.

[0015] 2. In this application, the cooperation between the insert and the sleeve facilitates the quick alignment of the splicing base and the expansion base. At the same time, the insert is used to lock the rod and fix the sleeve, which ensures the ease of disassembly and assembly of the splicing base and the expansion base, thereby further improving the ease of use of the reducer with the dustproof structure.

[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 some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A speed reducer with a dustproof structure includes a body 1 and a vent integrated on one side of the body 1. An expansion seat 2 fixedly connected to the body 1 is integrated on the outside of the vent. A splicing seat 3 is fixedly connected to the outer wall of the expansion seat 2. A strip groove 5 is opened on the side of the splicing seat 3 away from the expansion seat 2. A driving component 4 is fixedly connected to the outer wall of the splicing seat 3. A sealing strip 9 and a pushing component for horizontally pushing the sealing strip 9 are integrated between the output end of the driving component 4 and the interior of the splicing seat 3.

[0025] The driving component 4 drives the transmission rod 10 to rotate. The transmission rod 10 provides traction force to the screw seat 11 and the sealing strip 9 by screwing it into the screw seat 11. The sealing strip 9 slides along the smooth rod 13 through the bottom sliding sleeve 12. The sealing strip 9 gradually overlaps with the corresponding strip groove 5 until the strip groove 5 is completely closed. This ensures that the heat dissipation process of the machine body 1 is stable. At the same time, the opening size of the strip groove 5 can be adjusted according to the usage requirements, or even the strip groove 5 can be directly closed to ensure the dustproof effect when the reducer is not in use, thereby effectively improving the stability of the reducer.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a insert 8 is fixedly connected to the outer wall of the splicing base 3. The insert 8 is detachably connected to the outer wall of the expansion base 2. A retaining sleeve 6, which is fixedly connected to the outer wall of the expansion base 2, is fitted on the outer side of the insert 8. A locking rod 7 is screwed onto the inner wall of the retaining sleeve 6. The open end of the locking rod 7 abuts against the outer wall of the insert 8. Through the cooperation of the insert 8 and the retaining sleeve 6, the splicing base 3 and the expansion base 2 can be quickly aligned. At the same time, the insert 8 fixes the locking rod 7 and the retaining sleeve 6, which ensures the convenience of assembling and disassembling the splicing base 3 and the expansion base 2, thereby further improving the ease of use of the reducer with the dustproof structure.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the pushing assembly includes a transmission rod 10 and a limiting part for limiting the axial position of the seal 9. The transmission rod 10 is fixedly connected to the output end of the drive member 4. The outer wall of the transmission rod 10 is screwed to a screw seat 11 that is fixedly connected to the outer wall of the seal 9. The limiting part includes a smooth rod 13 and a sliding sleeve 12 that are fixedly connected to the inner wall of the splicing base 3 and the bottom of the seal 9, respectively. The inner wall of the sliding sleeve 12 is slidably connected to the outer wall of the smooth rod 13. The drive member 4 drives the transmission rod 10 to rotate. The transmission rod 10 provides traction force to the screw seat 11 and the seal 9 by screwing it to the screw seat 11. The seal 9 slides along the smooth rod 13 through the sliding sleeve 12 at the bottom. An elastic pad is fixedly connected to the front end face of the seal 9, which does not affect the sliding of the seal 9 while ensuring the airtightness between the seal 9 and the inner wall of the splicing base 3.

[0028] Working principle: The drive component 4 drives the transmission rod 10 to rotate. The transmission rod 10 provides traction force to the screw seat 11 and the sealing strip 9 by screwing it into the screw seat 11. The sealing strip 9 slides along the smooth rod 13 through the bottom sliding sleeve 12. The sealing strip 9 gradually overlaps with the corresponding strip groove 5 until the strip groove 5 is completely closed. This ensures that the heat dissipation process of the machine body 1 is stable. At the same time, the opening size of the strip groove 5 can be adjusted according to the usage requirements, or even the strip groove 5 can be directly closed to ensure the dustproof effect when the reducer is not in use. This effectively improves the stability of the reducer. Through the cooperation of the insert 8 and the clamp 6, the splicing seat 3 and the expansion seat 2 can be quickly aligned. At the same time, the insert 8 is fixed to the locking rod 7 and the clamp 6, which ensures the convenience of disassembling and assembling the splicing seat 3 and the expansion seat 2, thereby further improving the convenience of using the reducer with the dustproof structure.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
