A small-sized finite linear motion guide unit is provided in which there is provided a rack-and-pinion arrangement to prevent any discrepancy between retainer plates to make sure of relative sliding movement of guideways. A rack is composed of teeth portions and a pair of connecting bars to fasten the teeth thereon. The connecting bars are different in widthwise length to form asymmetrical shapes. The grooves for a rack made on the guideway includes a middle groove to get the rack to mate with the pinion, and sidewise grooves lying on both sides of the middle groove and having the connecting bars different in widthwise length to make an asymmetric shape.

Embodiments of this disclosure are directed to devices that allow for adjusting of device parameters in a manner that does not involve power dissipation in an essential way. Thus, power demands when such devices are used in applications can be insignificant. This applies to both springs and inerters, which constitute basic lossless building blocks of mechanical device systems, and are analogues of inductors and capacitors in electrical circuits. Embodiments of this disclosure are also directed to a lossless adjustable 2-port transformer, and realization of mechanical translational and rotary transformers are set forth in the following. Embodiments of this disclosure allow for reduction of power demands in adjusting device parameters.

A removable winch handle assembly for engaging a winch gear within a gearbox comprises: a handle receiver having at least a portion thereof exposed outside the gearbox, a seal between the handle receiver and the gear box, an engagement mechanism in the gearbox, the engagement mechanism coupled to the handle receiver to rotate with the handle receiver, wherein rotation of the engagement mechanism engages the winch gear, and a winch handle selectively coupled to the handle receiver, wherein, rotation of the winch handle causes rotation of the handle receiver when attached, the winch handle detachable from the handle receiver, wherein the gearbox opening is sealed by the seal when the winch handle is detached from the handle receiver.

An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis and mounted in the housing for performing a pivoting about the second rotary axis. The driven shaft is coupled to the drive shaft by a gear mechanism having a scotch yoke mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The scotch yoke mechanism includes a cross slider receiving the drive pin and having a sliding support extending perpendicular to the first rotary axis. The cross slider is guided in the housing by at least two elastically deformable elements. The driven shaft is coupled to the cross slider by a pivotable crank arm, converting a rotary motion of the drive shaft into a reciprocating of the driven shaft.

A variable wobbler plate has a stub shaft and a pivot shaft. The pivot shaft has a smaller diameter portion and a larger diameter portion. The smaller diameter portion has a generally cylindrical outer periphery with a flat over a limited circumferential extent and a diameter to opposed portions of the generally cylindrical portion defining a first distance. A second distance is defined from an end of the smaller diameter portion spaced furthest from the stub shaft to an end of the larger diameter portion spaced closest to the stub shaft and measured along a central axis of the pivot shaft and defines a second distance. A ratio of the first distance to the second distance is between 0.60 and 0.75. An integrated drive generator and a method are also disclosed.

Robot includes an assembled component having a fixed member and a moving member. The moving member includes a multi-hole bar member and a multi-hole circular plate. The multi-hole bar member has a width four times longer than its thickness. The multi-hole bar member includes a set of connecting holes running through the multi-hole bar member along a thickness direction of the multi-hole bar member. The multi-hole circular plate has a central hole and fixed holes distributed around the central hole and arranged circumferentially. The fixed member includes a multi-hole plate and a multi-hole bent plate. The thickness of the multi-hole plate is the same as the thickness of the multi-hole bar member. A bent portion is formed by bending at least one end of the multi-hole bent plate. The fixed holes are arranged in a matrix on the multi-hole plate and distributed on the multi-hole bent plate in a matrix.
