Description

Technical Field

[0001] This utility model belongs to the technical field of speed reducer devices, and in particular relates to an aluminum alloy housing for a speed reducer. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear and worm drives enclosed in a rigid housing. It is commonly used in speed reduction transmission devices between a prime mover and a driven machine.

[0003] According to the published patent CN218207700U, a reducer housing includes a main body, a top shell at the upper end of the main body, a shaft shell fixedly mounted on the side of the main body, a cover plate at the upper end of the shaft shell, a sponge block fixedly connected to the lower end of the cover plate, and a water inlet hole at the upper end of the cover plate. A sliding groove allows a fixing block to slide within the groove, while a fixing hole moves simultaneously with the fixing block. The fixed hole, once adjusted to its position, facilitates fixing the main body in different environments, which is beneficial for practical use. However, it still has the following shortcomings:

[0004] The aforementioned equipment is simply installed on the vehicle body or other equipment using bolts and other parts, resulting in poor stability of the device. Furthermore, the installation process requires tools such as wrenches, which is very inconvenient. At the same time, the reducer housing is directly exposed to the outside environment, and when the housing is subjected to external impacts, it may deform, affecting the transmission of the internal parts. Therefore, we propose an aluminum alloy housing for the reducer. Utility Model Content

[0005] The purpose of this utility model is to provide a reducer aluminum alloy housing. Through the positioning mechanism and the protective mechanism, it solves the problem that when the above-mentioned equipment is used, the reducer housing is simply installed on the vehicle body or other equipment by bolts and other parts, which makes the stability of the device poor. Moreover, the installation process requires the use of tools such as wrenches to assist in the installation, which is very inconvenient. At the same time, the reducer housing is directly exposed to the outside world. When the housing is subjected to external impacts or other factors, it may deform and affect the transmission of the internal parts.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an aluminum alloy housing for a speed reducer, including a mounting base. A protective cover is slidably connected to the outer wall of the mounting base, and the speed reducer housing is fixedly connected to the top outer wall of the mounting base. A positioning mechanism is provided on the inner wall of the mounting base.

[0008] The positioning mechanism includes a rotating shaft, the outer wall of which is rotatably connected to the inner wall of the mounting base. A worm gear is fixedly connected to the outer wall of the rotating shaft. Several limiting rods are fixedly connected to the inner wall of the mounting base near the worm gear. A worm is rotatably connected to the inner wall of the mounting base near the worm gear. The outer wall of the worm meshes with the outer wall of the worm gear. A rotating plate is fixedly connected to the outer wall of the rotating shaft. Several arc-shaped grooves are formed on the inner wall of the rotating plate. Fixed shafts are slidably connected to the inner walls of several arc-shaped grooves.

[0009] Furthermore, a top plate is fixedly connected to the outer wall of the fixed shaft, the outer wall of the top plate is slidably connected to the inner wall of the mounting base, and a protective mechanism is provided on the outer wall of the mounting base.

[0010] Furthermore, the protective mechanism includes several limiting plates, and the outer walls of the limiting plates are fixedly connected to the outer wall of the protective cover.

[0011] Furthermore, the inner wall of the mounting base near the limiting plate is provided with several sliding grooves, and the inner walls of the several sliding grooves are slidably connected with slide rails.

[0012] Furthermore, a number of telescopic rods are fixedly connected to the outer wall of the slide rail, and a number of springs are fixedly connected to the outer wall of the slide rail near the telescopic rods. The outer walls of the telescopic rods and the outer walls of the springs are all fixedly connected to the inner wall of the slide groove.

[0013] Furthermore, a slide plate is slidably connected to the inner wall of the slide rail, and several telescopic rods are fixedly connected to the outer wall of the slide plate.

[0014] Furthermore, a number of springs are fixedly connected to the outer wall of one end of the slide plate near the telescopic rod 2. The outer walls of the springs 2 and the outer wall of the telescopic rod 2 are both fixedly connected to the inner wall of the slide rail. A number of positioning holes are provided on the inner wall of the slide plate.

[0015] Furthermore, a rod is slidably connected to the inner wall of the positioning hole, and a spring is fixedly connected to the outer wall of the rod. The outer wall of the spring is fixedly connected to the outer wall of the limiting plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a worm gear on the rotating shaft, allows the mounting base with the reducer housing fixed to be installed on an external transmission device such as a vehicle seat when the equipment is needed. Rotating the worm will drive the worm gear to rotate, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft will drive the rotating plate to rotate, causing the fixed shaft to slide in the arc groove, thereby driving the fixed shaft to move. The movement of the fixed shaft will drive the top plate to slide in the mounting base, thus installing the top plate on the external device. This makes it easier for installers to install the reducer onto the external equipment more quickly and accurately. Moreover, the installation method of the device is simple and convenient, reducing the time for subsequent adjustments and calibrations, and improving the overall installation efficiency.

[0018] 2. This utility model incorporates telescopic rods within the slide rail. During equipment use, the top plate is installed on the external device, fixing the position of the mounting base. Multiple insert rods are pulled outward to align with the positioning holes. Subsequently, the limiting plate is placed on the slide plate, and then the insert rods are released. At this point, the springs, due to their own elasticity, cause the insert rods to return to their original position, thus inserting them into the positioning holes and fixing the position of the limiting plate. When the protective cover is subjected to external force and shakes, it effectively protects the reducer housing, preventing the housing from being deformed by external impacts, which could damage the internal transmission components and affect the normal operation of the reducer.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-6 As shown, this utility model is a reducer aluminum alloy housing, including a mounting base 1, a protective cover 101 slidably connected to the outer wall of the mounting base 1, a reducer housing 102 fixedly connected to the top outer wall of the mounting base 1, and a positioning mechanism 2 provided on the inner wall of the mounting base 1. The protective cover 101 can protect the reducer housing 102 and prevent it from being subjected to external forces, which could cause deformation and affect the normal transmission of the transmission parts inside the reducer housing 102.

[0031] The positioning mechanism 2 includes a rotating shaft 201, the outer wall of which is rotatably connected to the inner wall of the mounting base 1. A worm gear 203 is fixedly connected to the outer wall of the rotating shaft 201. Several limiting rods 202 are fixedly connected to the inner wall of the mounting base 1 near the worm gear 203. The limiting rods 202 can limit the movement trajectory of the rotating plate 205, so that it can only rotate between the multiple limiting rods 202, preventing the top plate 208 from falling off due to excessive rotation of the limiting rods 202. A worm 204 is rotatably connected to the inner wall of the mounting base 1 near the worm gear 203. The outer wall of the worm 204 meshes with the outer wall of the worm gear 203. A rotating plate 205 is fixedly connected to the outer wall of the rotating shaft 201. Several arc-shaped grooves 206 are provided on the inner wall of the rotating plate 205. A fixed shaft 207 is slidably connected to the inner wall of the arc-shaped grooves 206. The arc-shaped grooves 206 can prevent the fixed shaft 207 from jamming during movement.

[0032] A top plate 208 is fixedly connected to the outer wall of the fixed shaft 207. The outer wall of the top plate 208 is slidably connected to the inner wall of the mounting base 1. A protective mechanism 3 is provided on the outer wall of the mounting base 1. The protective mechanism 3 includes several limiting plates 301. The outer walls of the limiting plates 301 are all fixedly connected to the outer wall of the protective cover 101. When the limiting plates 301 are fitted onto the sliding plate 306 and fixed by the insert rod 310, the position of the protective cover 101 can be limited. Several sliding grooves 302 are provided on the inner wall of the mounting base 1 near the limiting plates 301. Slide rails 303 are slidably connected to the inner walls of the sliding grooves 302. Several telescopic rods 304 are fixedly connected to the outer wall of the slide rails 303 near the telescopic rods 304. Several springs 305 are fixedly connected to the outer wall of the slide rails 303 near the telescopic rods 304. The telescopic rods 304 can limit the movement trajectory of the springs 305 to prevent the springs 305 from breaking during the extension and retraction process.

[0033] The outer walls of several telescopic rods 304 and the outer walls of springs 305 are fixedly connected to the inner wall of the slide rail 302. A slide plate 306 is slidably connected to the inner wall of the slide rail 303. Several telescopic rods 307 are fixedly connected to the outer wall of the slide plate 306. When the protective cover 101 moves, it drives the limiting plate 301 to move, thereby causing the slide plate 306 to move. By buffering and protecting the slide plate 306, the protective cover 101 can be protected to a certain extent. Several springs 308 are fixedly connected to the outer wall of the end of the slide plate 306 closest to the telescopic rods 307. The outer walls of the springs 308 and the outer walls of the telescopic rods 307 are all connected to the slide rail 303. The inner wall of the slide plate 306 is fixedly connected to the inner wall. Several positioning holes 309 are provided on the inner wall of the slide plate 306. The position of the insertion rod 310 can be fixed through the positioning holes 309. When the insertion rod 310 is inserted into the positioning hole 309, the limiting plate 301 can be fixed on the slide plate 306. The insertion rod 310 is slidably connected to the inner wall of the positioning hole 309. The outer wall of the insertion rod 310 is fixedly connected to the outer wall of the limiting plate 301. The spring 311 can always press against the insertion rod 310 through its own elastic force, so that it is inserted into the positioning hole 309, thereby preventing the limiting plate 301 from falling off by itself.

[0034] One specific application of this embodiment is:

[0035] When the operator needs to use the equipment, the mounting base 1, which secures the reducer housing 102, is installed on an external transmission device such as a vehicle seat. Rotating the worm gear 204 causes the worm wheel 203 to rotate, which in turn rotates the rotating shaft 201. The rotation of the rotating shaft 201 causes the rotating plate 205 to rotate, causing the fixed shaft 207 to slide within the arc-shaped groove 206. This movement of the fixed shaft 207 causes the top plate 208 to slide within the mounting base 1, thus installing the top plate 208 onto the external device and fixing the position of the mounting base 1. Multiple insert rods 310 are pulled outwards to align with the positioning hole 309. Then, the limiting plate 301 is placed on the sliding plate 306. The insert rods 310 are then released. At this time, the spring 311 will move the insert rods due to its own elasticity. 310 is reset, which allows the insertion rod 310 to be inserted into the positioning hole 309, fixing the position of the limiting plate 301. When the protective cover 101 is shaken by external force, it will drive the slide plate 306 to slide in the slide rail 303. At the same time, the slide rail 303 can slide in the slide groove 302. When the slide rail 303 moves, it will simultaneously stretch or compress the telescopic rods 307 and springs 308 on both sides. The movement of the slide rail 303 will drive the telescopic rods 304 and springs 305 on both sides to stretch or contract simultaneously. The springs 308 and 305 will drive the slide rail 303 and slide plate 306 to reset due to their own elasticity. This can provide a certain buffering effect for the protective cover 101, thereby preventing the protective cover 101 from hitting the internal transmission parts when it moves.
