DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0022] The utility model provides Figure 1 to Figure 4 A high-efficiency single-head rotary reducer shown in the figure includes a reducer body 1, on which an output shaft 2 is arranged. Considering that the length of the output shaft 2 is generally fixed, it sometimes limits the docking installation with the actuator, which requires adjusting the installation position of the reducer body 1. Even after the adjustment, the problem still cannot be solved. In order to improve the applicability of the single-head rotary reducer, an extension shaft 4 is slidably arranged at one end of the output shaft 2 away from the reducer body 1. The extension shaft 4 is spline-matched with the output shaft 2, so that the extension shaft 4 can slide on the output shaft 2 to meet different docking lengths; at the same time, when the output shaft 2 rotates, it will drive the extension shaft 4 to rotate synchronously. The spline matching is an existing common technology and will not be described here.

[0023] The end of the extension shaft 4 away from the output shaft 2 is provided with a docking end 9, and a first protrusion 10 is fixedly connected to the outer wall of the docking end 9. When in use, the extension shaft 4 is docked and installed with the actuator through the docking end 9 and the first protrusion 10.

[0024] In order to adjust the position of the extended shaft 4, a ring sleeve 5 is rotatably connected to the extension shaft 4, and an adjustment component is arranged between the ring sleeve 5 and the outer shell of the reducer body 1. The adjustment component is arranged in two groups, and the two groups of adjustment components are symmetrically distributed about the extension shaft 4. The adjustment component includes a first threaded rod 6, a second threaded rod 7 and an adjustment sleeve 8. The first threaded rod 6 is fixedly connected to the outer shell of the reducer body 1, and the second threaded rod 7 is fixedly connected to the ring sleeve 5. One end of the adjustment sleeve 8 is threadedly connected to the first threaded rod 6, and the other end of the adjustment sleeve 8 is threadedly connected to the second threaded rod 7.

[0025] During operation, the adjusting sleeve 8 is rotated. Since one end of the adjusting sleeve 8 is threadedly connected to the first threaded rod 6, and the other end of the adjusting sleeve 8 is threadedly connected to the second threaded rod 7, the distance between the ring sleeve 5 and the outer shell of the reducer body 1 is adjusted, so that the extended shaft 4 can slide on the output shaft 2 to meet different docking lengths, thereby improving the applicability and installation efficiency of the single-head rotary reducer. At the same time, the cooperation between the first threaded rod 6, the second threaded rod 7 and the adjusting sleeve 8 can improve the rotation stability of the extended shaft 4.

[0026] The utility model provides structures such as an extension shaft 4, a ring sleeve 5 and an adjustment component, so that the extension shaft 4 can slide on the output shaft 2 to meet different docking lengths, improve the applicability and installation efficiency of the single-head rotary reducer, and the adjustment component can improve the rotation stability of the extension shaft 4.

[0027] Considering that the connector models of the actuators are different, when connected to the reducer body 1, the connectors often do not match, which causes great inconvenience in use. In order to further improve the applicability of the single-head rotary reducer, a spare part 14 is provided on the docking end 9. When used, spare parts 14 of more sizes can be provided, and flexible selection can be made according to specific use requirements to improve the use efficiency. The spare part 14 includes a second annular groove 13, a docking sleeve 15, a second protrusion 16 and a groove 17. The docking sleeve 15 is inserted into the outside of the docking end 9, and the groove 17 is provided on the inner wall of the docking sleeve 15. The groove 17 cooperates with the first protrusion 10. The second protrusion 16 is fixedly connected to the outer wall of the docking sleeve 15. The second annular groove 13 is provided on the outer wall of the docking sleeve 15. The second annular groove 13 is located at the end of the docking sleeve 15 close to the output shaft 2.

[0028] A first annular groove 3 is provided on the outer wall of the extension shaft 4. The first annular groove 3 is located at the end of the extension shaft 4 away from the output shaft 2. A threaded sleeve 11 is rotatably connected to the first annular groove 3. The threaded sleeve 11 can both rotate and slide on the first annular groove 3. A threaded groove matching the threaded sleeve 11 is provided on the outer wall of the second annular groove 13.

[0029] Specifically, select a spare part 14 of appropriate size, insert the docking sleeve 15 on the extension shaft 4, and the first protrusion 10 is clamped in the inside of the groove 17, rotate the threaded sleeve 11, and since the outer wall of the second annular groove 13 is provided with a threaded groove that cooperates with the threaded sleeve 11, the docking sleeve 15 and the threaded sleeve 11 are docked, so that the docking sleeve 15 and the extension shaft 4 form a whole, and then the docking sleeve 15 is docked and installed with the actuator.

[0030] By providing structures such as the spare component 14 and the threaded sleeve 11, a suitable spare component 14 can be flexibly selected according to specific usage requirements, thereby improving the docking installation efficiency.

[0031] In order to facilitate the rotation of the threaded sleeve 11 , a plurality of anti-slip grooves 12 are provided on the outer wall of the threaded sleeve 11 .
