Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a servo motor with planetary gear set, including servo motor 1, fixed mounting has a shell 2 on the lateral wall of 1 one of them side of driving motor, servo motor 1's output runs through and extends to in the shell 2 and sun gear 3 of fixedly connected with, it is provided with a driving shaft 4 to be the form of encircleing about sun gear 3 on servo motor 1's the lateral wall, the fixed cover in inside of shell 2 has connect a bearing 5, the inside cover of bearing 5 is equipped with three planetary gear 6, the one end that servo motor 1 was kept away from to sun gear 3 runs through and extends to in the shell 2 and meshes with three planetary gear 6 mutually.

The axes of the servo motor 1, the sun gear 3, the driving shaft 4, the bearing 5 and the shell 2 are overlapped.

Wherein, the centers of the three planet gears 6 are arranged in a superposition shape with the axial lead of the sun gear 2.

Specifically, when the utility model is used, the sun gear 3 can be driven to rotate by the servo motor 1, the sun gear 3 can drive the three planetary gears 6 to operate by meshing with the three planetary gears 6, so that the driving shaft 4 and the bearing 5 can be driven by the three planetary gears 6, and the bearing 5 can drive the external driving shaft, thereby improving the output torque of the servo motor 1 when the servo motor 1 operates, further precisely controlling the output precision of the servo motor 1, avoiding the additional connection of the servo motor 1 into a speed reducer, reducing the volume of external equipment of the servo motor 1, and facilitating the use of the servo motor 1.
