Problems solved by technology

[0003] The defect of the existing technology is that most of the current flexible angle bearings adopt the notch type design. The rotation range is limited by the size of the notch. The rotation range generally does not exceed ±30°, which limits its application in the actual demand of large rotation angles. More than 90°, and the rotation range of some pendulum mirrors is required to be greater than 60°. At present, the existing technology can only use the multi-stage series connection method of bushing-coupling-sleeve to achieve twice the time of ordinary notched angular bearings. range of motion

Abstract

The invention discloses a bearing and relates to a high-precision angle bearing and an angle adjusting method. The bearing consists of an internal plane cross spring and a cylindrical shell and provides high-precision angle rotation, low hysteresis and zero frictional loss. The bearing is compact in mechanism, small in size and convenient to mount, can realize high-precision angle positioning and is applied to aviation, spaceflight and high-precision positioning transmission equipment.

Description

technical field [0001] The invention belongs to the field of flexible bearing design and machinery, and in particular relates to a high-precision angle bearing and an angle adjustment method. Background technique [0002] At present, as the accuracy of torsional positioning of instruments and equipment is getting higher and higher, high-precision angular 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, oscillating mirrors, read / write heads for optical or magnetic disks, measurement sensors, etc. [0003] The defect of the existing technology is that most of the current flexible angle bearings adopt the notch type design. The rotation range is limited by the size of the notch. The rotation range generally does not exceed ±30°, which limits its application in the actual demand of large rotation angles. ...
