Abstract

The invention belongs to the technical field of machining, and relates to a pitching motion transmission rocking frame device, in particular to a three-layer rocking frame device with two degrees of freedom. The three-layer rocking frame device comprises a left inner ring, a middle inner ring, a left intermediate ring, balls, an outer ring, a toothed arc, a right intermediate ring, a right inner ring and an electromagnet. The device is of a three-layer structure and has two degrees of freedom, high-low motion is achieved through two sorts of pitching transmission, and two motion layers can be integrated into one layer through an electromagnet projecting shaft.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a pitching motion transmission cradle device, in particular to a three-layer cradle device with two degrees of freedom. Background technique [0002] The cradle device is a large-scale bearing with a special structure that can simultaneously bear comprehensive loads such as axial load, radial load, and turning moment. It integrates multiple functions of support, rotation, transmission, and fixation. It is mainly used in pitching mechanical arm equipment. A general cradle device is usually a single-degree-of-freedom double-layer: it is composed of an inner layer and an outer layer, one layer is fixed to the body of the pitching mechanical arm equipment, and the other layer is connected with the mechanical arm to achieve pitching motion. This kind of cradle device can only realize pitching motion through a kind of transmission mode. Contents of the invention [0003]...
