Abstract

The invention discloses a flexible bearing for a symmetrical spiral crossed reed. The bearing comprises single ring-shaped reed bodies, spacers and cylindrical pins, wherein the spacers are arranged between the two single ring-shaped reed bodies; and the cylindrical pins penetrate through pin holes in the single ring-shaped reed bodies and the spacers. The cylindrical pins and the pin holes are matched with one another, so that the overlapped single ring-shaped reed bodies are connected with the spacers to form a whole body so as to form the flexible bearing for the symmetrical spiral crossed reed. The bearing is divided into a moving rigid body and a fixed rigid body through a first notch and a second notch. The bearing disclosed by the invention adopts a linear cutting machining technology, wherein a pre-forming body is firstly manufactured and then is locked by the cylindrical pins, and the notches, installing holes and output holes are machined. The single ring-shaped reed bodies with different numbers are overlapped with one another to form a flexible bearing with a four reed units, six reed units, eight reed units or the like.

Description

technical field [0001] The present invention relates to a flexible bearing, more particularly, to a flexible bearing with symmetrical helical cross reeds. Background technique [0002] Flexible bearings are now more and more widely used, and its working principle is to use the flexible unit to deform under the action of external force to generate relative rotation. Due to the advantages of no friction, no gap, self-centering, no lubrication, no maintenance, and vacuum application, flexible bearings are favored by researchers engaged in precision positioning, micro-motion platforms and other precision fields, and have been used in low temperature Spectrometers, light source synchrotrons, adjustment of meteorological satellite optics, adaptive field adjustment mechanisms on astronomical telescopes, alignment mechanisms for microwave antennas on spacecraft, etc. [0003] Because the angle range of the notched flexible hinge is too small, it is not suitable for the design of fl...
