摘要： A reduction gear has pins that extend across and contact a first swing body and a second swing body and are swung by the first swing body and the second swing body. A first radial direction groove forming body has radial direction grooves formed in the same number (Za) as the pins to allow the pins to slide in a radial direction. A second radial direction groove forming body has radial direction grooves formed in the same number as the pins to allow the other ends of the pins to slide in the radial direction. A wave shape depressed portion forming body has wave shape depressed portions contacting the pins formed along a circumferential direction (Zb). Then, the difference between Za and Zb is 1.

摘要： A lens barrel includes a stationary barrel, a rotary barrel, and a movable barrel. The movable barrel includes a cam follower fitted to a straight groove in the stationary barrel and a cam groove in the rotary barrel. The surface of the cam follower to be in contact with the inner wall surface of the cam groove and the surface of the cam follower to be in contact with the inner wall surface of the straight groove have an arc shape convex toward the outside, and the cam follower is in point contact with the inner wall surfaces of the cam groove and the straight groove. The cam follower includes a first slit that is cut in from the distal end toward a proximal end thereof in parallel to an axis and a second slitcut in from an outer peripheral portion of the cam follower toward an inner peripheral portion.

摘要： A ball type speed reducer includes: an eccentric disk cam rotating in synchronization with an input-side rotating body; a shaking body fitted relatively rotatably to an outer circumference side of the eccentric disk cam to be shaken; balls rollably housed in a ball holding portion of the shaking body; and a fixing member having a first side face portion facing one side face of the shaking body. Radial grooves for radially guiding the balls are formed in the first side face portion. An output-side rotating body has a second side face portion facing the other side face of the shaking body. An annular corrugated groove for guiding the balls circumferentially in an undulating manner is formed in the second side face portion. The balls are engaged with the radial grooves and the corrugated groove and are rolled inside the radial grooves and the corrugated groove as the shaking body is shaken.

摘要： The retainer is provided so as to be prevented from being rotatable with respect to the rotary shaft, and rotation of the input-side rotary member is reduced in speed and transmitted to the output-side rotary member through intermediation of the balls which engage with both of the ball engagement grooves. A raceway center line of the second ball engagement groove is formed of a wave-shaped curve. When a speed reduction ratio of the speed reducer is represented by “i”, the wave-shaped curve has such a shape that the balls which engage with the first ball engagement groove engage with the second ball engagement groove at a given rotation angle (θ) of the input-side rotary member in a state in which the output-side rotary member is at a rotation angle (iθ).

摘要： A harmonic pin ring gear system comprises an input shaft, an output shaft, two outer gears each with internal toothing and a single inner gear with external toothing. The inner gear is arranged concentrically to a first outer gear and in axial direction inside the first outer gear. A drive means extends between the two outer gears and the inner gear and comprises a pin-retaining ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in axial direction from the pin-retaining ring. A rotary transmitter lifts the drive means off the external toothing of the inner gear and presses the drive means into the internal toothing of the outer gears.

摘要： The improved motorized gearbox mechanism of the present invention includes a plurality of cam-actuated gear block assemblies, which transfer power from an integral rotor and stator assembly contained in a cam/rotor assembly, to a secondary or output gear element. Each gear block assembly includes a gear block having a surface that periodically interfaces with a secondary or output gear element. When energized, the stator assembly interacts with the rotor assembly inducing the cam/rotor assembly to rotate about its central axis, thereby driving the output gear element via the plurality of cam-actuated gear block assemblies. The motorized gearbox mechanism may be powered electrically, hydraulically, pneumatically or by steam, or any conventional power source that can be adapted to use an integral stator/rotor assembly configured in the cam assembly body to generate rotative power in the cam/rotor assembly.
