Problems solved by technology

However, the traditional notch-type flexible hinge has a small range of motion, and it is difficult to adapt to some occasions with large corners.
Although the range of motion of the ordinary reed flexible hinge is improved, the center of rotation drifts seriously, and it is difficult to improve its rotation accuracy in the case of large deformation.

Abstract

The distributive leaf shaped rotary flexible hinge is manufactured with one cylinder and through integral machining in a linear cutting machine, and has one through hole, three pairs of leaf shaped reeds, three inner arms, and three outer installation holes. The present invention has symmetrically distributed flexibility design of curved reeds, high axial rigidity and radial rigidity, increased rotation range and small rotation axis drift. As one kind of excellent rotary flexible hinge with great deformation, the present invention is suitable for use in great stroke precise control mechanism.

Description

technical field [0001] The present invention relates to a flexible hinge, more particularly to a distributed blade-shaped rotating flexible hinge, and the international patent classification belongs to F16C11 / 00. Background technique [0002] Flexible hinge refers to a kinematic pair structure that uses elastic deformation of materials to generate relative motion under the action of external force or moment, which is very different from the structure of traditional rigid kinematic pairs. A flexible hinge is a typical flexible element in a flexible mechanism. Compared with traditional rigid hinges (mechanisms), flexible hinges and flexible mechanisms have many advantages: (1) can be integrated (or integrated) design and processing, so it can simplify the structure, reduce volume and weight, and avoid assembly; (2) There is no gap and friction, and high-precision movement can be realized; (3) It is free from wear and long life; (4) It is free from lubrication and pollution; (...
