Planetary transmission having a segmented ring

摘要

A planetary gear-set for continuously varying the output ratio between torque and rotational velocity, in which a central static sun-gear is considered as a reference to all other components. The structural aspects include a set of segments of a ring gear each such segment includes a linked couple of cogwheels. Another set of couples of linked cogwheels, is a sun-gear follower and the coupled member is output transfer cogwheel. A mechanism for changing the orientation of the output transfer cogwheel with respect to the sun-gear follower. A transient link connects between the above two separate systems of sets.

1. A planetary gear-set for continuously varying the output ratio between torque and rotational velocity, in which a sun-gear is considered as a reference to all other components, said system comprising:
a first set of segments of a ring gear, each such segment includes at least a permanently linked couple of cogwheels of which at least one cogwheel receives power and is capable of changing its distance from said sun gear its axle is not bound to a carrier, and at least another cogwheel that passes on power to a terminal collecting gear the axle of which power-passing cogwheel is bound to a carrier; a second set of couples of cogwheels, each such couple including also at least a link to permanently keep said couple of cogwheels constantly meshed, wherein in each such couple one cogwheel is a sun-gear follower and another is a ring engaging gear and wherein the axle of said ring engaging gear is not bound to a carrier; a mechanism for changing the distance of said ring engaging gear with respect to said sun-gear follower, and wherein power is received from a source at least through a carrier of said sun-gear followers.
