Problems solved by technology

The rotation range of the flexible bearing with this notch structure limits its application in the actual demand for large rotation angles. For example, the range of motion of the bearing of the deployable mechanism is generally required to be greater than 90°, and the rotation range of some pendulum mirrors is required to be greater than 60°, etc.

Abstract

The invention discloses a compact flexible bearing with a large rotation angle range, which belongs to the technical field of flexible bearing design. The axes of the bushings coincide and are arranged at a certain distance in the axial direction. The two bearing bushes are placed opposite to each other and located inside the two bushings respectively; each set of spring pieces has the same structure, consisting of three spring pieces arranged in sequence horizontally, vertically and horizontally. The three leaf springs do not contact each other along the axial direction of the sleeve; the first bush and the first bearing bush are connected together through the first set of spring leaves; the first bearing bush and the second bearing bush are connected together through the second set of spring leaves; The second bearing bush is connected with the second bushing through the third set of spring sheets. The bearing has many advantages, such as compact structure, small size, convenient connection with other external parts, convenient mass production, simplified installation steps, and improved production and assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of flexible bearing design, in particular to a structural design of a flexible bearing with a compact structure and a large rotation angle range. Background technique [0002] As instruments and equipment require higher and higher precision for torsion positioning, flexible bearings have been more and more widely used in the field of precision positioning due to their characteristics of no gap, high motion sensitivity, and high resolution, such as light source synchrotrons, scanning Instruments, pendulum mirrors, read / write heads for optical discs or magnetic disks, measurement sensors, etc. In addition, the flexible bearing uses the deformation of the flexible spring to achieve relative motion, without lubrication, mechanical friction, and will not be stuck, so it can be used in harsh conditions such as vacuum, large temperature difference, and strong radiation. [0003] Most of the current flexible bearin...
