Abstract

The invention provides a circular guiding mechanism based on the Roberts mechanism, comprising: an outer connecting ring; an inner connecting ring, the inner connecting ring is coaxial with the outer connecting ring; There are a plurality of Roberts mechanisms connecting the outer connecting ring and the inner connecting ring as one. The circular guide mechanism based on the Roberts mechanism provided by the present invention is an integrated structure, without the need to process multiple parts for assembly, and can be completed by using the wire electric discharge cutting process, the processing is simple, and it is easy to achieve high processing accuracy, which is beneficial Improve guidance accuracy.

Description

technical field [0001] The invention relates to the technical field of a bearingless precision circular guide mechanism, in particular to an integrated flexible circular guide mechanism based on a Roberts mechanism. Background technique [0002] In equipment with precise circular motion such as radar antennas, theodolites, and precision instruments, it is often necessary to use a circular guiding mechanism to improve the accuracy of circular motion and reduce motion errors in non-moving directions. Commonly used circular guide mechanisms are rolling bearings and joint bearings. When these bearings are in use, lubricants are generally required, so that there is a possibility of chemical contamination in the equipment. When the bearing is running, the components in the bearing rub against each other, which makes it easy for particle pollution to mix into the equipment. Due to the construction principle of the bearing, there is a gap between the components in the bearing, whi...
