Spherical gear and fluted disk mechanism

Abstract

The invention discloses a spherical gear and fluted disk mechanism comprising a continuous spherical gear and a discrete fluted disk. The continuous spherical gear is a hemispherical body, and the hemispherical surface of the continuous spherical gear is provided with a plurality of toothed slots; the discrete fluted disk is in a disk shape, and the disk body of the discrete fluted disk is provided with a plurality of convex teeth engaged with the toothed slots; and the continuous spherical gear can do spatial motion on the discrete fluted disk. One convex tooth of the discrete fluted disk ofthe spherical gear and fluted disk mechanism is inserted into one toothed slot of the continuous spherical gear, and three-degree-of-freedom motions of deflection, pitching and rotation around the axis can be achieved; and mutual transformation between planar motion and spherical motion can be achieved, and stable meshing transmission and no transmission principle error can be ensured through themeshing mode that the convex teeth of the fluted disk are inserted among concave spherical teeth.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a ball gear chainring mechanism. Background technique [0002] Ball gear transmission is a novel transmission form, which has unique advantages in changing the transmission direction of the mechanism. [0003] At present, the planar motion of most toothed discs is realized through the universal platform. Since the universal platform occupies a large space, it is not suitable for transmitting motion in a small space. A new type of ball gear transmission mechanism is urgently needed. On the other hand, it is necessary to meet the requirement of greatly reducing the space occupied by the universal platform device. Contents of the invention [0004] The purpose of the present invention is to provide a ball gear chainring mechanism to solve the above-mentioned problems in the prior art, so that the space occupied by the gear chainring mechanism is small, and it can ...
