Title:
LINEAR GEAR MECHANISM TRANSMITTING AT VARIABLE ANGLE
Document Type and Number:
WIPO Patent Application WO/2019/114452
Kind Code:
A1
Abstract:
A linear gear mechanism transmitting at a variable angle, in which a pair of linear gears having intersecting shafts constitutes a transmission pair, comprising a driving wheel (3) and a driven wheel (1), wherein the driving wheel (3) and the driven wheel (1) are each composed of a gear body and a line tooth; contact lines of a driving wheel line tooth (4) and a driven wheel line tooth (2) mesh according to a pair of spatial conjugate curves; one or more line teeth are on the driving wheel (3); the line tooth on the driven wheel (1) is a line tooth that has the property of transmitting at a variable angle, and during the transmission process, the mechanism may adjust the transmission angle of the gear pair which has intersecting shafts, thus causing engagement points to form on different contact lines while the transmission ratio remains unchanged and transmission is stable. The contact lines of the driving wheel line tooth (4) and driven wheel line tooth (2) of the linear gear mechanism are different at different transmission angles, and different meshing lines may cause the gear mechanism to have the same transmission ratio; thus, transmission at an continuously variable angle and a fixed transmission ratio between two shafts may be achieved.
