[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1-Figure 3 The utility model provides an embodiment: a reducer that is easy to maintain, including a reducer body 1, a first flange 3 is fixedly connected to the front side of the reducer body 1, a second flange 4 is arranged on the front side of the first flange 3, the second flange 4 is connected to the first flange 3 by bolts, an input rod 5 is fixedly connected to the front side of the second flange 4, a mounting ring 6 is fixedly connected to the middle part of the input rod 5, a plurality of extension columns 7 are fixedly connected to the front side of the mounting ring 6, a contact rod 8 is rotatably connected to the outer wall of the extension column 7, an adjustment block 13 is rotatably connected to the adjacent side of the plurality of contact rods 8, a positioning ring 9 is rotatably connected to the left end of the front side of the mounting ring 6, a screw 10 is rotatably connected to the top of the positioning ring 9, a rotating block 15 is threadedly connected to the outer wall of the screw 10, a first rotary disk 11 is rotatably connected to the front side of the rotating block 15, a plurality of locking blocks 14 are fixedly connected to the front side of the first rotary disk 11, a second rotary disk 16 is fixedly connected to the front side of the locking block 14, a plurality of limit sleeves 12 are rotatably connected to the rear side of the second rotary disk 16, and a quick release assembly is arranged on the right side of the reducer body 1.
[0030] In order to improve the connection applicability of the output heads of different motors, for the motor output head with a diameter larger than the connecting pipe of the reducer body 1, the output head can be placed at the center position of the second flange 4 first, and then the screw 10 is rotated to make the rotating block 15 gradually approach the positioning ring 9 along the threaded connection. In the process of the movement of the rotating block 15, the first rotating disk 11 and the second rotating disk 16 are driven to rotate, and then the plurality of contact rods 8 are pushed to move to the adjacent side through the set limit sleeve 12. The inner walls of the plurality of adjustment blocks 13 are provided with a rubber anti-slip layer, and the adjustment block 13 is crescent-shaped, and then the adjustment block 13 is tightly attached to and fixed to the motor output rod. When used subsequently, the rotation of the motor output rod can drive the input rod 5 connected to the mounting ring 6 to rotate, and then realize its deceleration function through the output end of the reducer body 1.
[0031] The contact rod 8 is slidably connected to the inner wall of the limiting sleeve 12. When the first rotary disk 11 rotates, the limiting sleeve 12 can be driven to move by the rotation, thereby changing the moving direction of the contact rod 8 to achieve the clamping and fixing function.
[0032] The multiple adjustment blocks 13 are slidably connected to each other, and the narrowest distance between the multiple adjustment blocks 13 is limited by the slidably connected therebetween.
[0033] A plurality of limiting sleeves 12 are rotatably connected to the front side of the first rotary disk 11 , and the positions of the limiting sleeves 12 are limited by the first rotary disk 11 and the second rotary disk 16 .
[0034] The quick-release assembly includes a third flange 17 slidably connected to the right side of the reducer body 1 , a surrounding shell 2 is fixedly connected to the middle of the right side of the third flange 17 , and a plurality of hand-tightening bolts 18 are threadedly connected to the right side of the third flange 17 .
[0035] The surrounding shell 2 can be removed from the reducer body 1 by turning a plurality of hand-tightening bolts 18 in sequence, thereby the inside of the reducer body 1 can be debugged and maintained. After the operation is completed, the surrounding shell 2 can be placed on the corresponding fixed position of the reducer body 1, and the third flange 17 and the reducer body 1 can be fixed by hand-tightening the bolts 18 in sequence, thereby achieving the effect of convenient maintenance.
[0036] The hand tightening bolt 18 passes through the third flange 17 and is threadedly connected to the right side of the reducer body 1 .
[0037] Working principle: When the staff needs to install and maintain the reducer, they can remove the enclosure 2 from the reducer body 1 by sequentially rotating multiple hand-tightening bolts 18, so as to facilitate the debugging and maintenance of the reducer. After the operation is completed, just put the enclosure 2 back to the corresponding fixed position of the reducer body 1, and tighten the bolts in sequence to make the third flange 17 firmly connected to the reducer body 1 to ensure the convenience of maintenance.
[0038] In daily use of the reducer, in order to enhance the adaptability to the connection of different motor output heads, the motor output head with a diameter larger than the connecting pipe of the reducer body 1 can be placed in the center of the second flange 4. Subsequently, by rotating the screw 10, the rotating block 15 gradually approaches the positioning ring 9 along the threaded connection. In this process, the movement of the rotating block 15 will drive the first rotating disk 11 and the second rotating disk 16 to rotate, and then push the multiple contact rods 8 to move toward the center through the limit sleeve 12. These contact rods 8 tightly fit and fix the adjustment block 13 to the motor output rod. In the subsequent use process, the rotation of the motor output rod will drive the input rod 5 connected to the mounting ring 6 to rotate, and the deceleration function is realized through the output end of the reducer body 1.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
