AI Technical Summary

Technical Problem

The existing rotary motion system is costly and has complex control in complex motion control, making it difficult to achieve complex cycloidal motion, and the terminal motion coverage is limited, making it difficult to be suitable for applications such as monitoring systems and radar systems.

Method used

Using a non-orthogonal universal joint mechanism, the rotation angular velocities of the first and second parts are different through the driving assembly. Combined with the bevel gear assembly and the limit frame, complex cycloidal movement is achieved, and only a single motor is required to drive and the terminal platform is moved. Wide coverage.

Benefits of technology

It realizes the guidance of complex cycloidal motion, reduces costs, improves the reliability of motion, and has a wide range of motion coverage of the terminal platform, which is suitable for applications such as monitoring systems and radar systems.

Abstract

A motion guide device, comprising a base (P), a first component (10), a second component (20) and a driving assembly, wherein the first component (10) is rotationally connected to the base (P), such that the first component (10) can rotate around a first rotating shaft (R1) relative to the base (P); the second component (20) is rotationally connected to the first component (10), such that the second component (20) can rotate around a second rotating shaft (R2) relative to the first component (10); an included angle between the first rotating shaft (R1) and the second rotating shaft (R2) is defined as a, where 0°＜a＜90°; and the driving assembly makes a rotational angular velocity of the first component (10) relative to the base (P) not equal to a rotational angular velocity of the second component (20) relative to the first component (10). The motion guide device uses a simple non-orthogonal universal joint mechanism, and provides a guide for a complex cycloid motion, such that the device has low costs, and provides a high motion reliability.
