Description
Technical Field
[0001] This utility model relates to the field of speed reducer technology, specifically a speed reducer housing structure that is easy to install. Background Technology
[0002] A speed reducer is a speed reduction transmission device that matches the speed and transmits torque between a prime mover (such as an electric motor or internal combustion engine) and a working machine or actuator. Prime movers usually have high speeds, while working machines often require lower speeds to operate normally. Speed reducers can convert the high-speed rotation of the prime mover into the low-speed rotation required by the working machine, thus meeting the speed requirements of different working scenarios.
[0003] The working principle of a speed reducer is mainly to change the speed and torque through the meshing of transmission components such as gears, worm gears, and planetary gear systems. Taking a common gear reducer as an example, it consists of multiple gears of different sizes. The speed reduction and torque increase are achieved through the gear ratio. When the driving gear (connected to the prime mover) rotates, it drives the driven gear (connected to the working machine) to rotate. Since the driven gear has more teeth than the driving gear, the speed of the driven gear will decrease, while the torque will increase.
[0004] In the existing installation process of reducer housings, a large number of bolts are often used for installation and fixation. This cumbersome and time-consuming process greatly affects the installation efficiency of reducers. Therefore, developing a reducer housing structure that is easy to install is of great practical significance. Utility Model Content
[0005] The purpose of this utility model is to provide a gearbox housing structure that is easy to install, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a gearbox housing structure that is easy to install, including a housing body and a connecting seat. A base is fixedly connected to the bottom of the housing body, and a positioning groove is provided at the bottom of the base. A positioning boss that matches the positioning groove is fixedly connected to the upper surface of the connecting seat. A fixing slot is provided on the outer side wall of the positioning boss, and a connecting component is fixedly connected to the outer side wall of the base.
[0007] Preferably, the connecting assembly includes a connecting plate fixedly installed on the outer wall of the base, and a mounting shell is fixedly connected to the side of the connecting plate away from the base, with a limit groove formed on the outer surface of the mounting shell.
[0008] Preferably, a movable block is slidably connected to the inner wall of the mounting shell, a movable rod is fixedly connected to the side of the movable block near the connecting plate, and a fixed insert is fixedly connected to the end of the movable rod away from the movable block.
[0009] Preferably, the size of the fixed insert block matches the size of the fixed slot, the connecting plate has a through hole to facilitate the sliding of the movable rod, and a connecting rod is fixedly connected to the outer surface of the movable rod.
[0010] Preferably, the outer wall of the connecting rod is slidably connected to the inner wall of the limiting groove, and a pull rod is fixedly connected to the end of the connecting rod away from the movable rod. Several anti-slip strips are fixedly connected to the outer surface of the pull rod.
[0011] Preferably, the movable block has an annular groove on the side away from the movable rod, and a return spring is inserted into the annular groove. The mounting shell has a threaded groove on the side away from the connecting plate.
[0012] Preferably, a threaded block is threadedly connected to the inner wall of the threaded groove, and a bottom cover is fixedly connected to one end of the threaded block. An annular groove two is opened on the side of the threaded block away from the bottom cover, and the annular groove two abuts against the end of the return spring away from the annular groove one.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the design of the connecting components makes the installation process simpler and faster. Workers only need to pull and release the lever to insert and remove the fixing block, thus completing the installation and disassembly of the base and the connecting seat, which greatly shortens the installation time and improves the installation efficiency. The return spring is installed in the mounting shell through the threaded block and the bottom cover. When the return spring is damaged or its elasticity is weakened, workers can easily remove the threaded block by rotating the bottom cover to replace the return spring, which improves the maintainability and service life of the structure.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Please see Figures 1-6 The present invention provides the following two preferred embodiments:
[0024] Example 1: A gearbox housing structure that is easy to install includes a housing body 1 and a connecting seat 3. The connecting seat 3 is fixed to the installation foundation, such as the ground or equipment frame, by bolts. A base 2 is fixedly connected to the bottom of the housing body 1. A positioning groove 7 is provided on the bottom of the base 2. A positioning boss 5 that matches the positioning groove 7 is fixedly connected to the upper surface of the connecting seat 3. A fixing slot 6 is provided on the outer side wall of the positioning boss 5. Through the cooperation between the positioning boss 5 and the positioning groove 7, the base 2 and the connecting seat 3 can be accurately positioned, providing an accurate position reference for subsequent installation. A connecting component 4 is fixedly connected to the outer side wall of the base 2.
[0025] The connecting assembly 4 includes a connecting plate 42 fixedly installed on the outer wall of the base 2. A mounting shell 41 is fixedly connected to the side of the connecting plate 42 away from the base 2. A limit groove 44 is formed on the outer surface of the mounting shell 41. A movable block 412 is slidably connected to the inner wall of the mounting shell 41. A movable rod 413 is fixedly connected to the side of the movable block 412 close to the connecting plate 42. A fixed insert block 43 is fixedly connected to the end of the movable rod 413 away from the movable block 412.
[0026] During use, when installing the main body 1 of the housing, the operator first aligns the positioning boss 5 of the connecting seat 3 with the positioning groove 7 of the base 2. The precise positioning and quick docking of the base 2 and the connecting seat 3 are achieved through the cooperation of the positioning boss 5 and the positioning groove 7. Then, the operator pulls the pull rod 45 by hand. The pull rod 45 drives the connecting rod 46 to move axially along the limiting slide groove 44. The movement of the connecting rod 46 drives the movable rod 413 and the fixed plug 43 to move into the mounting shell 41. During this process, the movable block 412 will compress the return spring 414, so that the return spring 414 stores elastic potential energy. When the positioning boss 5 and the positioning groove 7 are docked, the operator releases the pull rod 45. At this time, the return spring 414 releases the stored elastic potential energy and pushes the movable block 412 to move towards the connecting plate 42. The movable block 412 drives the movable rod 413 and the fixed plug 43 to move together, so that the fixed plug 43 is inserted into the fixed slot 6 on the outer wall of the positioning boss 5, thereby completing the quick installation of the base 2 and the connecting seat 3.
[0027] Example 2: The size of the fixing block 43 matches the size of the fixing slot 6, ensuring that the fixing block 43 can be accurately inserted into the fixing slot 6, realizing a stable connection between the base 2 and the connecting seat 3. The connecting plate 42 has a through hole to facilitate the sliding of the movable rod 413. The outer surface of the movable rod 413 is fixedly connected to the connecting rod 46. The outer wall of the connecting rod 46 is slidably connected to the inner wall of the limiting slide groove 44. The end of the connecting rod 46 away from the movable rod 413 is fixedly connected to the pull rod 45. The outer surface of the pull rod 45 is fixedly connected to several anti-slip strips, making it convenient for the staff to pull the pull rod 45, making the operation more labor-saving and less prone to slipping.
[0028] An annular groove 47 is provided on the side of the movable block 412 away from the movable rod 413. A return spring 414 is inserted into the annular groove 47. A threaded groove 48 is provided on the side of the mounting shell 41 away from the connecting plate 42. A threaded block 49 is threadedly connected to the inner wall of the threaded groove 48. A bottom cover 410 is fixedly connected to one end of the threaded block 49. An annular groove 411 is provided on the side of the threaded block 49 away from the bottom cover 410. The depth of the annular groove 47 and the annular groove 411 is greater than the wire diameter of the return spring 414 to prevent it from coming out. The annular groove 411 abuts against the end of the return spring 414 away from the annular groove 47. With this structure, the return spring 414 can provide elastic force for the fixed plug 43, so that it can automatically insert into the fixed slot 6 during installation. At the same time, when disassembly is required, the fixed plug 43 can be easily pulled out from the fixed slot 6. Moreover, the return spring 414 can be easily replaced by rotating the bottom cover 410, which improves the practicality and maintainability of the structure.
[0029] When the return spring 414 needs to be replaced after a period of use due to weakened elasticity or damage, the operator manually rotates the bottom cover 410. The bottom cover 410 drives the threaded block 49 to rotate, causing the threaded block 49 to disengage from the threaded groove 48 of the mounting housing 41. Then, the old return spring 414 is removed from the annular groove 1 47 and annular groove 2 411. One end of the new return spring 414 is inserted into the annular groove 1 47 of the movable block 412, and the other end is inserted into the annular groove 2 411 on the threaded block 49. Finally, the bottom cover 410 is rotated again, causing the threaded block 49 to be screwed into the threaded groove 48 of the mounting housing 41, thus completing the replacement of the return spring 414.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
