摘要： A coaxial gear set comprising: a crankshaft which can be rotated about an axis of rotation and has at least one connecting rod bearing; and multiple, preferably at least three, pistons, each connected to the crankshaft by means of a connecting rod and which each have a toothing with at least one tooth on a first end face facing away from the axis of rotation. The coaxial gear set also comprises: a hollow shaft having internal toothing, wherein the pistons are located inside the hollow shaft when viewed in a plane normal to the axis of rotation; and a guide unit, wherein the pistons are each linearly guided in the guide unit and can be moved back and forth parallel to a radial direction normal to the axis of rotation, as a result of which the toothings of the first end faces of the pistons can be successively brought into meshing engagement with the internal toothing and out of meshing engagement with said internal toothing.

摘要： A cam transmission mechanism includes a rotary disk, a camshaft, contact members and a housing. The rotary disk has a periphery formed with equidistant projections, any two adjacent ones of which define an accommodating recess. The camshaft includes a shaft rod and a cam body that has at least one groove communicated with some of the recesses of the rotary disk. The groove and the recesses cooperate to form a plurality of confining spaces, within which the contact members are accommodated freely rollably for rotation transfer from the camshaft to the rotary disk. The housing is connected to the rotary disk for confining the contact members in the confining spaces, respectively.

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： The gearbox mechanism of the invention includes a plurality of cam-actuated gear block assemblies, which transfer power from a power shaft 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. In a preferred embodiment the interface surface comprises a plurality of projections or teeth which correspond to complementary projections or gear teeth on the output gear element. Each gear block assembly further includes a gear block, a rocker arm, cam followers and/or gear block tracking post, which connect or link the gear block to a cam assembly, which in turn is connected to a power source. The cam assembly includes about its circumference a unique pathway or groove for each cam followers and/or gear block tracking post of a particular gear block assembly so that the movement of the gear block may be controlled in two or three dimensions in accordance with a certain design parameter.

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).
