Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a high-stability worm gear reducer. Background Technology

[0002] A worm gear reducer is a mechanical transmission device that utilizes a worm wheel and a worm, primarily used to reduce rotational speed and increase output torque. This type of reducer is very common in industrial applications, especially where it is necessary to reduce the speed of a high-speed motor or engine to a suitable operating level.

[0003] When using a worm gear reducer, the worm wheel and worm need to cooperate with each other. However, this cooperative driving method is prone to vibration, which can easily affect the stability of the worm gear reducer. Furthermore, when using the drive worm, the worm wheel needs to be rotated. If the worm is displaced, it will affect the overall stability of the reducer. Therefore, we propose a high-stability worm gear reducer. Utility Model Content

Detailed Implementation

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a high-stability worm gear reducer, including a reducer housing 1 and a mounting frame 2. The mounting frame 2 is fixedly installed at the bottom of the reducer housing 1. The surface of the reducer housing 1 and the top of the mounting frame 2 are fixedly connected by a reinforcing plate 25 made of rigid material. The inside of the reducer housing 1 is rotatably connected to a drive worm 4 through two sets of first fixed bearing seats 3. The inside of the reducer housing 1 is rotatably connected to a worm gear body 6 that meshes with the drive worm 4 through a second fixed bearing 5. Auxiliary positioning mechanisms 7 for secondary reinforcement of the reducer housing 1 are provided on both sides of the mounting frame 2. Two sets of worm gear limiting mechanisms 8 for supporting and limiting one end of the drive worm 4 are fixedly installed on one side of the reducer housing 1. Support mechanisms 9 for preventing deformation of the worm gear limiting mechanisms 8 are provided at the top and bottom of the worm gear limiting mechanisms 8.

[0018] The drive worm 4 can drive the worm wheel body 6 to rotate, thereby achieving coordinated drive. After the mounting bracket 2 is installed and fixed, the auxiliary positioning mechanism 7 can reinforce the entire device to prevent excessive shaking of the reducer housing 1. When the drive worm 4 rotates, the worm limit mechanism 8 can prevent the drive worm 4 from excessive displacement when driving the worm wheel body 6 to rotate. The support mechanism 9 can support and limit the worm limit mechanism 8 to prevent deformation of the worm limit mechanism 8.

[0019] Please see Figure 1 The auxiliary positioning mechanism 7 includes a connecting block 10, a positioning groove 11, a positioning frame 12, a positioning block 13, and a mounting groove 14. The connecting block 10 is fixedly installed on the side wall of the mounting frame 2. The connecting block 10 has a serrated positioning groove 11. The bottom of the positioning frame 12 is fixedly connected to the positioning block 13, which engages with the positioning groove 11. Both the mounting frame 2 and the positioning frame 12 have multiple sets of mounting grooves 14.

[0020] During the installation of the reducer body 1 and the mounting bracket 2, the locking screw is passed through the mounting groove 14 on the mounting bracket 2 to complete the installation and fixation of the reducer body 1. Then, the positioning block 13 on the positioning bracket 12 is inserted into the serrated positioning groove 11. Then, the locking screw is passed through the mounting groove 14 on the positioning bracket 12 to complete the fixation of the positioning bracket 12. In this way, the positioning block 13 and the positioning groove 11 can be used to complete the secondary auxiliary fixation of the reducer body 1.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The worm gear limiting mechanism 8 includes a limiting groove 15, a connecting frame 16, a fixing block 17, a limiting ball 18, and a fixing plate 19. The driving worm gear 4 has a limiting groove 15. The fixing block 17 is fixedly connected to one side of the connecting frame 16. The limiting ball 18, which fits against the inner wall of the limiting groove 15, is rotatably connected to one side of the fixing block 17. The fixing plate 19 is fixedly connected to the other side of the connecting frame 16. The fixing plate 19 is installed on the reducer housing 1 by multiple sets of locking bolts 20.

[0022] During installation, the connecting frame 16 is fixed to the gearbox housing 1 by multiple sets of locking bolts 20. After the connecting frame 16 is installed, the limiting ball 18 can fit into the inside of the limiting groove 15. The limiting ball 18 is rotatably connected to the fixing block 17. In this way, the limiting ball 18 can be used to support and limit one end of the drive worm 4 to prevent the drive worm 4 from displacing during use.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The support mechanism 9 includes a slide rail 21, a slider 22 and a support frame 23. The slide rail 21 is fixedly installed on the reducer housing 1, and the support frame 23 is fixedly installed on the connecting frame 16. A slider 22 that is slidably connected to the slide rail 21 is fixedly connected to one side of the support frame 23.

[0024] When installing the worm gear limiting mechanism 8, the slider 22 on one side of the support frame 23 can be slidably installed inside the slide rail 21. This arrangement facilitates the pushing of the limiting ball 18 into the limiting groove 15, and the support frame 23 can support the connecting frame 16, thereby preventing the connecting frame 16 from deforming during use.

[0025] Please see Figure 1 and Figure 2 The top of the reducer housing 1 is fixedly connected to a lifting ring 24, which facilitates the lifting and movement of the reducer housing 1.

[0026] In use, firstly, the drive worm 4 drives the worm wheel body 6 to rotate, thus achieving coordinated drive. After the mounting bracket 2 is installed and fixed, the auxiliary positioning mechanism 7 provides secondary reinforcement to the entire device, preventing excessive shaking of the reducer housing 1. When the drive worm 4 rotates, the worm limit mechanism 8 prevents excessive displacement of the drive worm 4 while driving the worm wheel body 6 to rotate. The support mechanism 9 supports and limits the worm limit mechanism 8, preventing deformation. When installing the reducer body 1 and the mounting bracket 2, the locking screw passes through the mounting groove 14 on the mounting bracket 2 to complete the installation and fixing of the reducer body 1. Then, the positioning block 13 on the positioning bracket 12 is inserted into the serrated positioning groove 11, and the locking screw is then passed through the mounting groove 14 on the positioning bracket 12 to complete the positioning of the reducer body 1. The fixing of the 2nd position allows for secondary auxiliary fixing of the reducer body 1 using the positioning block 13 and positioning groove 11. During installation, the fixing plate 19 of the connecting frame 16 is installed on the reducer housing 1 using multiple sets of locking bolts 20. After the connecting frame 16 is installed, the limiting ball 18 can fit against the inside of the limiting groove 15. The limiting ball 18 is rotatably connected to the fixing block 17, thus supporting and limiting one end of the drive worm 4 to prevent displacement of the drive worm 4 during use. When installing the worm limiting mechanism 8, the slider 22 on one side of the support frame 23 can be slidably installed inside the slide rail 21. This arrangement facilitates pushing the limiting ball 18 into the inside of the limiting groove 15, and the support frame 23 can support the connecting frame 16, thereby preventing deformation of the connecting frame 16 during use.

[0027] 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.
