Simultaneously, by setting up a collection mechanism, the debris can be automatically collected and sealed, facilitating subsequent debris processing.

Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a double-supported radial force-resistant speed reducer housing structure. Background Technology

[0002] The double-support radial force-resistant reducer is a precision transmission device with a double-support structure. Its core design enhances the radial load resistance through the double-sided support of the planetary carrier or bearings, while optimizing the size, weight and transmission accuracy. To protect the normal use of the reducer, a suitable housing structure is generally provided on the outside, which plays a good role in heat dissipation, lubrication and protection. When lubricating, it is only necessary to immerse the gear part of the reducer in lubricating oil, and the oil is lubricated by the rotation of the gear.

[0003] In the existing gearbox structure, the lubricating oil used for lubrication will produce a certain amount of metal shavings after long-term use. Therefore, the lubricating oil needs to be replaced regularly to ensure that the metal shavings do not affect the operation of the gearbox. However, directly replacing the lubricating oil will result in waste, and subsequent recycling requires staff to manually separate the metal shavings, which is very inconvenient.

[0004] Therefore, those skilled in the art have provided a dual-support radial force-resistant reducer housing structure to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-supported radial force-resistant reducer housing structure, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-support radial force-resistant reducer housing structure, comprising a lower housing, wherein a movable mechanism is provided inside the lower housing, the movable mechanism comprising an electric telescopic rod fixedly connected to the center of the lower inner wall of the lower housing, an oil storage tank fixedly connected to the upper end of the electric telescopic rod, a connecting frame placed inside the oil storage tank, connecting rods fixedly connected to the four corners of the lower end of the connecting frame, the four connecting rods passing through the oil storage tank and connecting to the bottom surface of the lower housing, a filter screen provided on the connecting frame, and an L-shaped plate fixedly connected to the inner wall of the lower housing.

[0007] As a further technical solution of this utility model, the movable mechanism also includes an L-shaped plate fixedly connected to the inner wall of the lower box, a reciprocating screw rotatably connected to the L-shaped plate, a moving rod being driven by a threaded sleeve on the reciprocating screw, and an adsorption roller rotatably connected to the moving rod, the adsorption roller contacting the surface of the filter screen.

[0008] As a further technical solution of this utility model, the movable mechanism also includes a rack fixedly connected to the oil storage tank, and a gear is fixedly connected to one end of the reciprocating screw near the L-shaped plate, the gear being able to mesh with the rack.

[0009] As a further technical solution of this utility model, a support plate is fixedly connected inside the lower housing. The support plate is located above the reciprocating screw, and its initial position is partially located inside the oil storage tank.

[0010] As a further technical solution of this utility model, a collection mechanism is provided inside the moving rod. The collection mechanism includes a collection box installed inside the moving rod. A scraper is connected to the collection box by a spring column, and the scraper is in contact with the surface of the adsorption roller.

[0011] As a further technical solution of this utility model, the collection mechanism also includes a soft cloth fixedly connected to one side wall of the collection box and the scraper. Two soft cloths are provided, located above and below the spring column respectively.

[0012] As a further technical solution of this utility model, the front and rear ends of the lower housing are fixedly connected with mounting parts, and heat sinks are fixedly connected to the side of the lower housing.

[0013] As a further technical solution of this utility model, an upper box is installed at the upper end of the lower box, and a shaft hole is provided at the connection between the lower box and the upper box.

[0014] This utility model provides a double-supported radial force-resistant reducer housing structure, which has the following advantages compared with the prior art:

[0015] By incorporating a movable mechanism, when metal debris is present in the lubricating oil inside the gearbox, the lubricating oil and metal debris can be automatically separated. This prevents metal debris from remaining in the lubricating oil for extended periods, which could affect the operation of the reducer. Furthermore, after separation, the separated debris can be removed from the filter screen to prevent it from re-entering the lubricating oil. This process is highly convenient as it requires no manual intervention from staff and reduces the need for frequent lubricating oil changes, thus minimizing resource waste. Additionally, the collection mechanism automatically collects and seals the debris, facilitating subsequent processing. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution for a dual-support anti-radial force reducer housing structure: it includes a lower housing 1, and an active mechanism is provided inside the lower housing 1. The active mechanism includes an electric telescopic rod 5 fixedly connected to the center of the lower inner wall of the lower housing 1. An oil storage tank 6 is fixedly connected to the upper end of the electric telescopic rod 5. A connecting frame 8 is placed inside the oil storage tank 6. Connecting rods 7 are fixedly connected to the four corners of the lower end of the connecting frame 8. The four connecting rods 7 pass through the oil storage tank 6 and connect to the bottom surface of the lower housing 1. A filter screen 9 is provided on the connecting frame 8. An L-shaped plate 10 is fixedly connected to the inner wall of the lower housing 1. The oil storage tank 6 is filled with lubricating oil. A sealing ring is provided at the penetration point between the connecting rods 7 and the oil storage tank 6 to prevent lubricating oil from leaking from the inside of the oil storage tank 6.

[0024] The moving mechanism also includes an L-shaped plate 10 fixedly connected to the inner wall of the lower housing 1. A reciprocating screw 11 is rotatably connected to the L-shaped plate 10. A moving rod 14 is connected to the reciprocating screw 11 via a threaded sleeve. An adsorption roller 15 is rotatably connected to the moving rod 14. The adsorption roller 15 contacts the surface of the filter screen 9. A sealing mechanism is provided at the notch between the moving rod 14 and the adsorption roller 15 to prevent lubricating oil from entering the interior of the moving rod 14.

[0025] The moving mechanism also includes a rack 13 fixedly connected to the oil storage tank 6, and a gear 12 fixedly connected to one end of the reciprocating screw 11 near the L-shaped plate 10. The gear 12 can mesh with the rack 13. When the rack 13 moves, it can drive the gear 12 to rotate, thereby rotating the reciprocating screw 11, and finally causing the moving rod 14 and the adsorption roller 15 to move on the surface of the filter screen 9 to achieve adsorption cleaning.

[0026] A support plate 4 is fixedly connected inside the lower housing 1. The support plate 4 is located above the reciprocating lead screw 11, and its initial position is partially located inside the oil reservoir 6. The support plate 4 is used for the installation of the reducer body, so that some parts of the reducer are located inside the oil reservoir 6, and the reducer parts are partially immersed in the lubricating oil.

[0027] The moving rod 14 is equipped with a collection mechanism, which includes a collection box 16 installed inside the moving rod 14. A scraper 18 is connected to the collection box 16 via a spring column 17. The scraper 18 is in contact with the surface of the adsorption roller 15. When the moving rod 14 moves under the action of the reciprocating screw 11, it can drive the adsorption roller 15 to rotate to clean the debris on the surface of the filter screen 9.

[0028] The collection mechanism also includes a soft cloth 19 fixedly connected to one side wall of the collection box 16 and the scraper 18. There are two soft cloths 19, located above and below the spring column 17 respectively. The soft cloths 19 will not affect the movement of the scraper 18, but will also block the collected debris.

[0029] Mounting components 20 are fixedly connected to the front and rear ends of the lower housing 1. Heat sinks 21 are fixedly connected to the side of the lower housing 1. The entire reducer can be installed through the mounting components 20. The heat sinks 21 are finned heat sinks, which have a good heat dissipation effect.

[0030] The upper box 2 is installed at the upper end of the lower box 1, and a shaft hole 3 is provided at the connection between the lower box 1 and the upper box 2.

[0031] The working principle of this utility model is as follows: After a period of use, some metal shavings will fall into the lubricating oil inside the oil storage tank 6 of the lower housing 1. At this time, the electric telescopic rod 5 is retracted, thereby moving the oil storage tank 6 downward. The connecting frame 8 and the filter screen 9, which are fixedly connected to the lower housing 1 by the connecting rod 7, will not move. Therefore, the filter screen 9 will gradually leak out of the oil storage tank 6, thus isolating the metal shavings inside the lubricating oil on the filter screen 9, preventing them from moving with the lubricating oil. When the filter screen 9 is completely removed from the oil storage tank 6, the gear 12 and the rack 13 are in perfect meshing contact. As bar 13 continues to move downwards along with oil storage tank 6, it drives gear 12 and reciprocating screw 11 to rotate. When reciprocating screw 11 rotates, moving rod 14 moves along filter screen 9, and under the action of friction, adsorption roller 15 rotates based on moving rod 14. The rotation of adsorption roller 15 will adhere metal debris on filter screen 9 to its own surface. At the same time, under the action of spring column 17, scraper 18 always makes full contact with the surface of adsorption roller 15, so that the metal debris adhering to its surface can be scraped into the collection box 16 for collection. During processing, simply remove moving rod 14 and pull out collection box 16.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
