Abstract

The invention discloses a one-way rotation damping bracket. The one-way rotation damping bracket comprises a support outer frame, a support inner frame and a damping mechanism; the support outer frame includes a support outer cylinder, and an annular support top plate fixed at the top of the inner wall of the support outer cylinder; the support inner frame includes a support inner cylinder, and an annular support baseplate fixed at the bottom of the outer wall of the support inner cylinder; the support outer cylinder, the support top plate, the support inner cylinder and the support baseplate surround an annular closed cavity; the support baseplate is provided with a damping oil inlet hole and a damping oil discharge hole; damping oil is filled in the annular closed cavity; the damping mechanism includes multiple damping paddles; the multiple damping paddles are fixed in the annular closed cavity, and are arranged in the peripheral direction; the length direction of the damping paddles is perpendicular to the support baseplate; and the multiple damping paddles are dipped in the damping oil. The one-way rotation damping bracket has the following advantages: a certain rotating damping is provided by using the moving damping of the damping paddles in the annular closed cavity, so that the shake caused by sudden stop after rotation of a stepper motor is effectively prevented.

Description

technical field

[0001] The invention relates to the technical field of steering damping mechanisms, in particular to a one-way rotation damping bracket. Background technique

[0002] In the field of automatic control equipment such as robots, especially for some high-precision mobile manipulators, in order to precisely control the rotation angle, a high-precision stepping motor with low starting current and small reluctance is generally used for rotation control; however Because the number of sensors and controllers on the manipulator is large, and the self-weight is large, the stepper motor with low reluctance will shake back and forth in a small range due to excessive inertia after it rotates and stops suddenly, which will affect the movement of the equipment. precision. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a one-way rotating damping bracket to avoid the phenomenon of shaking...
