Problems solved by technology

[0002] At present, in space motion machines involving two degrees of freedom, such as robot motion arms, large-scale mechanical working arms, and solar tracking, the rotation axis is in the form of a two-degree-of-freedom single axis, that is, an axis and a bearing are set for each degree of freedom. The main problems of this two-degree-of-freedom rotating shaft and bearing are: 1. It takes up a lot of space and is not compact; 2. The mechanical strength is not very high, and it is not suitable for sandstorm environments; 3. The production and maintenance costs are high; therefore, it is necessary to Improvements to existing systems

Embodiment 1

[0015] see figure 1 , in an embodiment of the present invention, a vertically integrated two-degree-of-freedom omnidirectional rotating shaft and bearing assembly is composed of a vertically integrated bearing part, a tapered shaft, a fastening screw part and a shaft support seat part, and the vertically integrated bearing part includes a vertical connection Body longitudinal surface 1, vertical connecting body horizontal surface 2, vertical integrated longitudinal bearing body 3, vertical integrated horizontal bearing body 4, vertical integrated longitudinal bearing 5 and vertical integrated horizontal bearing 6, the tapered shaft and fastening screw part include longitudinal axis pressure Tightening inner hexagon 7, horizontal axis pressing inner hexagon 8, fastening shaft and support seat nut 11, vertical taper shaft 12, horizontal taper shaft 13, longitudinal shaft body 14 and horizontal shaft body 15, the shaft support seat part includes longitudinal Shaft support seat 9 ...

Embodiment 2

[0017] see figure 2 , in the two-degree-of-freedom rotary motion with high mechanical strength, this vertical integrated structure can be used. In this structure, the vertical connecting body longitudinal surface 1 and the vertical connecting body transverse surface 2 are a solid steel body.

Embodiment 3

[0019] see image 3 , in the two-degree-of-freedom rotational motion with greater mechanical strength, this vertical integrated structure can be used. In this structure, the thickness of the vertical surface 1 of the vertical connector or the horizontal surface 2 of the vertical connector is the vertical integrated longitudinal bearing body 3 or the diameter of the vertical integral horizontal bearing body 4; the longitudinal surface 1 of the vertical connecting body and the horizontal surface 2 of the vertical connecting body are processed by steel.

[0020] The working principle of the present invention is: the vertical integrated bearing part is a vertical bearing with different planes in space, and the centerlines of the two bearings are perpendicular to different planes in space; the two ends corresponding to each pair of bearings are tapered shafts, which are respectively fixed on their respective support seats; One end of the shaft is a tapered shaft surface, which has ...

Abstract

The invention discloses perpendicularly integrated two-degree-of-freedom omnibearing rotating shafts and bearings. A perpendicular connecting body longitudinal surface and a perpendicular connecting body transverse surface are intersected, wherein a perpendicularly integrated longitudinal bearing body and a perpendicularly integrated transverse bearing body are positioned on the two sides of the perpendicular connecting body longitudinal surface and the perpendicular connecting body transverse surface; perpendicularly integrated longitudinal bearings are positioned at the two ends of the perpendicularly integrated longitudinal bearing body; perpendicularly integrated transverse bearings are positioned at the two ends of the perpendicularly integrated transverse bearing body; fastening shafts and support seat nuts are arranged on longitudinal shaft bodies and transverse shaft bodies; longitudinal tapered shafts are positioned at the lower ends of the longitudinal shaft bodies; transverse tapered shafts are positioned at the lower ends of the transverse shaft bodies; the longitudinal shaft bodies are connected with longitudinal shaft support seats; the transverse shaft bodies are connected with the transverse shaft support seats; the longitudinal tapered shafts are inserted into the perpendicularly integrated longitudinal bearings; the transverse tapered shafts are inserted into the perpendicularly integrated transverse bearings. The perpendicularly integrated two-degree-of-freedom omnibearing rotating shafts and the bearings are simple and compact in structure and flexible in rotation, and the production and maintenance cost of the two-degree-of-freedom omnibearing rotating shafts and bearings can be effectively lowered.
