<p>This device comprises a spherical part (1) equipped with an inclined circular annular groove, and continuously rotationally driven by a shaft (3), and an annular part (2) equipped with dog points (8), possibly with a ball, engaged in the annular groove; this part is securely fastened to the shaft (4), which constitutes the output of the oscillatory motion. The assembly is enclosed in a sealed casing (5) which contains an oil bath and carries the roller-contact bearings (16) which support the rotary input shaft (3) as well as other roller-contact bearings which support the oscillatory output shaft. The casing (5) may possibly be eliminated, the oil bath being limited to the inside of the spherical part (1). <IMAGE></p> |
