A torque transmission shaft is configured having increased coupling strength between end joints and a cylindrical member to achieve high transmission torque. Misalignment and disengagement of outer collars (connection members) is effectively prevented in the step of press fitting the torque transmission shaft to another component, such as a constant velocity joint. Circlips are fitted in annular grooves formed in the end joints. The circlips abut and lock the outer collars. The outer collars each include a smaller diameter portion, and an end surface of the smaller diameter portion includes a plurality of hollow portions.

The present invention relates to transferring torque between a first unit, such as a mobile machine or a robot, and a second unit, such as a fixed or stationary machine. The units are arranged such that a drive coupler of the first unit designed for delivering torque about a drive axis can engage the driven coupler, which belongs to the second unit and has a driven axis, along an engagement direction that is nearly perpendicular to the direction of the driven axis. A lateral displacement mechanism of the first unit achieves a first-order coaxial alignment between the drive and driven axes. Additional measures are provided for improving engagement, coupling and reducing the level of axial misalignment. The invention further pertains to a dual-mode torque delivery apparatus tolerant of imprecise alignment.

A safety device for a curtain controller is provided. The safety device comprises a base, a bead chain wheel, and a cover. A shaft sleeve having a conical shape is disposed in a through hole of the base to connect a shaft's terminal and thus be fixed in a sleeving hole, having a shape to fit the shaft sleeve, of the bead chain wheel, so that the motions of the shaft sleeve and the bead chain wheel are linked. A bead chain is wound on the bead chain wheel. When the bead chain is pulled down, the shaft sleeve can drive the rotation of the bead chain wheel. The upper part of the cover is pivotally connected to the base, and the lower part of the cover buckles the base. Therefore, when the bead chain is instantly pulled down, the cover can be opened to drop the bead chain wheel.

Flexurally mounted kinematic coupling with improved repeatability

Номер: US20140133897A1
Автор: Micheal Brendan O Ceallaigh
Принадлежит: Individual

A kinematic coupling apparatus where mating between two objects occurs at six contacting elements, each located and oriented in compliance with the laws of kinematic design, and where each mating surface is constrained in its normal direction while having relatively high compliance in the other five degrees of freedom. The contact surfaces are preferably planar. Each coupling element is mounted on a five degree of freedom flexure, known as a stud. For maximum stiffness in three orthogonal axes, the couplings are arranged in pairs, with each pair being parallel to its twin, and orthogonal to the other two pairs. For maximum torsional rigidity, each mating pair of mating surfaces is arranged at equal and maximum distance from the center of gravity of the object being located. For highest repeatability, a positive fluid pressure is applied between the mating surfaces immediately prior to the opposing surfaces making mating contact. The precise location of the contact surfaces can be controllably adjusted to sub-nanometer accuracy by means of a linear actuator in series and collinear with the central axis of each stud.
