[0026] Reference Figures 1-3, according to an embodiment of a low-vibration speed reducer of the present utility model, it includes a chassis 11 and a speed reduction box 12 connected to the chassis 11. An input motor flange adapter plate 13 is provided inside the left side surface of the speed reduction box 12. When a motor is installed on the motor flange adapter plate 13, the output shaft in the speed reduction box 12 outputs with high torque and low speed.

[0027] In order to prevent the motor installed on the motor flange adapter plate 13 from vibrating, a supporting mechanism is provided on the chassis 11. The supporting mechanism includes a chute 14 provided inside the chassis 11. A sliding plate 15 is slidably connected left and right inside the chute 14. A bearing plate 16 is hinged to the upper side surface of the sliding plate 15. A stabilizing plate 17 is hinged to the upper end of the bearing plate 16. The stabilizing plate 17 is used to abut against and support the motor. A locking assembly for locking the angle of the bearing plate 16 is further provided on the upper side surface of the sliding plate 15. In addition, it includes a lower pressing plate 41. The lower pressing plate 41 is connected to the stabilizing plate 17 by bolts, and the lower pressing plate is located on the upper side of the stabilizing plate 17. The motor will be clamped and locked by the lower pressing plate 41 and the stabilizing plate 17;

[0028] Bolting holes for fixing the position of the chassis 11 are provided inside the chassis 11. There are four such bolting holes, which are distributed in two columns left and right. The left bolting holes are provided inside the lower side surface of the chute 14. Two through slots 31 are provided front and back inside the sliding plate 15. The two through slots 31 and the two bolting holes distributed front and back inside the chute 14 are in the same front-back position. A bolt is also included. When it is necessary to install the low-vibration speed reducer on an installation platform, the staff first adjusts the position of the sliding plate 15, and then passes the bolt through the through slot 31 and the bolting hole and tightens it. At this time, the sliding plate 15 is locked in position relative to the chassis 11, and the chassis 11 is fixedly installed.

[0029] In addition, in this embodiment, the locking component includes a support rod 19 mounted on the upper side of the sliding plate 15. The upper end of the support rod 19 is hinged with a support plate 20, and the support plate 20 is used to support against the bearing plate 16. It also includes a support mechanism for controlling the up and down position of the support rod 19. The support mechanism includes a sleeve plate 21 fixed on the sliding plate 15. An upwardly penetrating lifting groove 22 is provided in the sleeve plate 21. A lifting rod 26 is rotatably connected in the lifting groove 22. The lifting rod 26 is inserted upward and threadedly connected into the support rod 19. A rotating shaft 23 is rotatably connected to the side surface of the lifting groove 22. The rotating shaft 23 extends outside the sleeve plate 21, and a rotating handle is installed at the end of the rotating shaft 23. The rotating shaft 23 is connected to the lifting rod 26 through a bevel gear set. The staff can drive the rotation of the rotating shaft 23 by rotating the rotating handle. When the rotating shaft 23 rotates, it will drive the rotation of the lifting rod 26 through the bevel gear set, and further make the support rod 19 move up and down. When the stabilizing plate 17 abuts against the motor installed on the motor flange adapter plate 13, and the support plate 20 supports and adheres to the bearing plate 16, the motor can be supported and the vibration can be reduced.

[0030] It should be additionally noted that when rotating the rotating handle, the staff needs to control the support rod 19 and prevent it from rotating.

[0031] In addition, in order to prevent the rotating handle from loosening when the entire chassis 11 vibrates, a convex platform 24 is fixedly provided on the upper side of the sliding plate 15. An arc-shaped groove 25 for accommodating the rotating shaft 23 is provided in the upper side surface of the convex platform 24. A through first pin hole is provided in the rotating shaft 23, and a second pin hole is provided in the arc-shaped groove 25. A pin 32 is commonly inserted into the first pin hole and the second pin hole. After the pin 32 is inserted, it will be difficult for the rotating shaft 23 to rotate again.

[0032] In order to make the control more accurate, taking the axis of the arc-shaped groove 25 as the center, no less than three second pin holes are equiangularly arranged in the arc-shaped groove 25.

[0033] In order to prevent relative movement from occurring after the support plate 20 adheres to the bearing plate 16, a plurality of convex plates distributed left and right are provided in the side surface of the support plate 20 away from the support rod 19. A plurality of grooves are equidistantly arranged left and right in the side surface of the bearing plate 16 close to the support plate 20, and the grooves are adapted to the shape of the convex plates. The convex plates can be inserted into the grooves to lock the relative position of the bearing plate 16 relative to the support plate 20.

[0034] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
