METHOD FOR MANUFACTURING CAMS OF ABRAMOV VA WAVE GEAR GENERATORS Russian patent published in 2017 - IPC F16H57/00 F16H53/00 

FIELD: machine engineering.

SUBSTANCE: method for manufacturing cams of wave gear generators of the outer and inner circuits involves execution of the cam circuit with a cutting tool or an electroerosive machining. The circuit is determined by setting two pairs of circular arcs. One of these pairs of circular arcs with centers located on the major axis of the ellipse equal to 2a, from the vertices of the ellipse to the center has a radius

.

Another pair of circles is located on the minor axis of the elliptical profile equal to 2b, and has a radius R = (I+G) / (2). Circular arcs with radius r are conjugated with circular arcs with radius R. I is the square of the difference between the lengths of the semiminor axis b and the focal parameter p of the cam ellipse, G is the product of the sum and difference of the lengths of the semimajor axis a and the semiminor axis b of the cam ellipse.

EFFECT: improved manufacturability.
