Motion transmitting devices

A two stage motion transmitting unit constructed from two motion transmitting devices each including:

• eccentric means,
• meshing means in the form of a series of linked but individually and independently movable meshing elements,
• wheel means formed with portions complementary to said meshing elements, and
• a series of individual movement-limiting means,
• wherein said eccentric means is disposed to cause said meshing elements individually and sequentially to wobble in and out of meshing engagement with successive said complementary portions, each of said individual movement-limiting means guiding in captive dependency always the same individual meshing element within specific limits of wobbling motion, said wobbling motion being in two degrees of freedom relative to each of said individual movement-limiting means, each of said devices having an input and an output, and wherein the output of one device is drivingly interconnected with the input of the other device.

A motion transmitting device including:

• wheel means,
• meshing means, and
• a series of individual movement-limiting means,
• wherein said meshing means is a series of linked but individually movable elements each caused to wobble in and out of contact with successive complementary to said meshing means portions formed at the circumference of said wheel means, while each of said elements is individually guided by the same individual movement-limiting means to have a substantially ovoidal motion relative to said same individual movement-limiting means.

A motion transmitting device including:

• a. eccentric means,
• b. meshing means in the form of a series of linked but individually and independently movable meshing elements,
• c. gear means formed with teeth defining a first pitch-circle about a first axis,
• d. a reaction element having a series of movement-limiting means all equidistantly arranged about a second axis, each of said movement-limiting means having a design center, all said design centers lying on a second pitch-circle;
• wherein each of said meshing elements is in captive dependency to one of said movement-limiting means but is free to have a wobbling motion in two degrees of freedom with reference to said one movement-limiting means;
• said first and second axes being parallel to one another and at a distance apart defining the eccentricity of said eccentric means, said eccentric means disposed to cause said gear means and movement-limiting means to rotate eccentrically with respect to one another, while at least one of said meshing elements drivingly interconnects one after the other of said teeth and one of said limiting means;
• said first and second pitch-circles intersecting one another.

A motion transmitting device including:

• a. a toothed disc rotatably journalled upon eccentric means on a rotating driving shaft;
• b. a reaction member having a series of substantially ovoidal apertures all equidistantly arranged about said driving shaft;
• c. a series of linked but individually movable meshing elements;
• wherein each such meshing element is in loose captive dependency to one of said apertures, but free to have a wobbling motion in two degrees of freedom with reference to said one aperture, whereby rotation of said eccentric means causes said meshing elements individually and sequentially to wobble, thereby drivingly interengaging tooth after tooth of said disc, thus transmitting an eccentrically rotating motion to said disc.

A motion transmitting device including:

• a. eccentric means;
• b. meshing means in the form of a series of linked but individually and independently movable meshing elements, said elements having pin means and each of said pin means having a geometric center;
• c. gear means formed with teeth means;
• d. a reaction member having a series of apertures each of said apertures having a design center and all said design centers lying on a circle;
• wherein each said pin means is in captive dependency to one of said apertures but free to have a wobbling motion in two degrees of freedom with reference to said one aperture;
• said eccentric means disposed to cause said gear means and reaction member to rotate eccentrically with respect to one another, while at least one of said meshing elements drivingly interconnects one after the other of said teeth means with one of said apertures;
• at any given moment the geometric centers of substantially half of said pin means lie on a semicircle, said circle and said semicircle intersecting one another at two points.
