Abstract
The present invention relates to a line gear mechanism with variable-angle transmission, which consists of a line gear pair having intersecting shafts which includes a driving line gear and a driven line gear. The driving line gear and the driven line gear are each composed of a wheel body and a line tooth. Contact curves of the driving line gear and the driven line gear mesh according to a pair of space conjugate curves. One or more line teeth are provided on the driving line gear. The line tooth on the driven line gear is a line tooth that has a property of variable-angle transmission. During transmission, the mechanism may adjust a transmission angle of the line gear pair having the intersecting shafts, thus causing meshing points to form on different contact curves while a transmission ratio remains unchanged and the transmission is stable.
