In addition, there are also some deficiencies in the connection method between the shaft connecting the load and the rotating shaft of the speed reducer. The connection process is often complex, the installation efficiency is low, and the firmness and reliability of the connection also need to be improved. Content of the Utility Model

A convex block corresponding to the chute is fixedly connected to the outer wall of the slip ring 34. The inner wall of the adjusting ring 31 is rotatably connected to a threaded sleeve 36, the inner wall of the threaded sleeve 36 is threadedly connected to a threaded rod 33, a slide block 37 is fixedly connected to the outer wall of the threaded rod 33, the outer wall of the threaded sleeve 36 is in contact with the outer wall of the installation frame 2, and the outer wall of the ring 35 is rotatably connected to the inner wall of the fixed shell 32.

[0023] The outer wall of the slide block 37 is slidably connected to the inner wall of the installation frame 2, the outer wall of the installation frame 2 is slidably connected to the outer wall of the adjusting ring 31, and the outer wall of the slip ring 34 is slidably connected to the outer wall of the rotating shaft 5. By sliding the slip ring 34 on the rotating shaft 5, the wheelbase can be changed. The fixing component 4 includes a threaded column 41, a limiting sleeve 42 is threadedly connected to the outer wall of the threaded column 41, and a soft sleeve 43 is fixedly connected to the outer wall of the threaded column 41.

[0024] A positioning block 44 is fixedly connected to the outer wall of the soft sleeve 43, and the positioning blocks 44 are arranged in a circular array along the central axis of the soft sleeve 43. One end of the threaded column 41 away from the limit sleeve 42 is fixedly connected to the outer wall of the slip ring 34. The outer wall of the soft sleeve 43 is slidably connected to the inner wall of the limit sleeve 42. By squeezing the soft sleeve 43 with the limit sleeve 42, the soft sleeve 43 can fix the connecting shaft.

[0025] Working principle:

[0026] During use, first install the mounting frame 2 on the reducer body 1 through bolts. It should be noted that when fixing the mounting frame 2, the pitch-changing component 3 needs to be aligned with the groove on the rotating shaft 5 and the pitch-changing component 3 is installed on the rotating shaft 5. Then the mounting frame 2 can be fixed on the reducer body 1. After the mounting frame 2 and the pitch-changing component 3 are installed, the connecting shaft of the load can be aligned with the center of the fixing component 4, and the connecting shaft is connected to the rotating shaft 5 through the fixing component 4.

[0027] When installing the pitch-changing component 3, only need to slide the slip ring 34 onto the rotating shaft 5. It should be noted that the convex block on the slip ring 34 is aligned with the groove on the rotating shaft 5, so as to fix the slip ring 34 on the rotating shaft 5. When pitch change is required, only need to rotate the threaded sleeve 36 to make the threaded sleeve 36 release the extrusion of the mounting frame 2, so as to release the locking of the adjusting ring 31. Then drive the adjusting ring 31 to slide by sliding the threaded rod 33. Since the adjusting ring 31 is connected to the circular ring 35 through the fixed shell 32, the slip ring 34 can be driven to move through the circular ring 35, so as to change the distance of the slip ring 34 on the rotating shaft 5.

[0028] When the position of the slip ring 34 is changed, only need to rotate the threaded sleeve 36 in the reverse direction to make the threaded sleeve 36 abut against the mounting frame 2. Since the threaded rod 33 slides in the mounting frame 2 through the slider 37, the mounting frame 2 is squeezed by the threaded rod 33 and the threaded sleeve 36 in both directions, so as to fix the threaded rod 33 on the adjusting ring 31, and then lock the position of the slip ring 34.

[0029] When using the fixing component 4, only need to slide the connecting shaft into the soft sleeve 43, and then rotate the limit sleeve 42 to make the limit sleeve 42 squeeze the soft sleeve 43, so as to squeeze the positioning block 44 on the soft sleeve 43 against the connecting shaft. After the positioning block 44 contacts the connecting shaft, rotate the limit sleeve 42 again to fix the connecting shaft and the threaded column 41.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Structures, devices, and operation methods not specifically described and explained in the present utility model shall be implemented by conventional means in the art without special instructions and limitations.
