An engagement assembly, a drawer, and a refrigerator having same. The engagement assembly comprises a first engagement part matching the drawer and a second engagement part matching a refrigerator body; one of the first and second engagement parts is a gear, and the other one is a rack; the rack has a tooth surface that allows the gear to travel; the rack comprises a main rack and an extension rack; when the drawer is in a closed state, the tooth surface has a first stroke length; when the drawer is in an opening process, the extension rack moves to a travel path of the gear so that the tooth surface has a second stroke length; when the drawer is in a closing process, the extension rack is reset the first stroke length is smaller than the second stroke length. The length of the tooth surface increases in the opening process.

An intermediate steering shaft for a motor vehicle includes an elastic element arranged and formed (i) at least partially in a first recess and second recess formed in a receiving section of a profile shaft, and (ii) at least partially in a recess formed in a first guide rail and a recess formed in a second guide rail, in order to apply a pretension to a respective guide arrangement.

The invention relates to a magnetic bearing assembly for contactless linear displacement of a rigid body relative to another rigid body along a linear displacement path.

The invention also relates to a linear guideway assembly implementing one or more such magnetic bearing assemblies.

The invention aims to provide a solution for the above identified problems, allowing linear displacement of a rigid body relative to another rigid body along a linear displacement path and in particular allowing control of a translational degree of freedom of a rigid body relative to another rigid body, said magnetic bearing assembly comprising: at least one magnetic bearing module being mounted to one of said rigid bodies and consisting of at least: a ferromagnetic core; a first magnetic element positioned on a first side of said ferromagnetic core; a coil being wound around said ferromagnetic core; at least a first static back iron being mounted to the other one of said rigid bodies and positioned, during use, at some gap distance from said one bearing module.

A positioning stage employs a constraining plate having three contact elements fixed therein, each contact element protruding from the constraining plate providing a lower engagement surface and an upper engagement surface. A first plate has at least two slots aligned for a first axis of translation. The slots are engaged by the lower engagement surfaces the contact elements. A second plate has at least two slots aligned for a second axis of translation. The slots are engaged by the upper engagement surface of two of the contact elements, thereby providing two axes of motion for positioning.

In a substrate stage, when a Y coarse movement stage moves in the Y-axis direction, an X coarse movement stage, a weight cancellation device, and an X guide move integrally in the Y-axis direction with the Y coarse movement stage, and when the X coarse movement stage moves in the X-axis direction on the Y coarse movement stage, the weight cancellation device move on the X guide in the X-axis direction integrally with the X coarse movement stage. Because the X guide is provided extending in the X-axis direction while covering the movement range of the weight cancellation device in the X-axis direction, the weight cancellation device is constantly supported by the X guide, regardless of its position. Accordingly, a substrate can be guided along the XY plane with good accuracy.

A track member or a movable member constituting a motion guide device includes a rolling part formed of a metal material contacting with a plurality of rolling bodies and forming a rolling body rolling surface a, a mounting part formed of a metal material having a mounting hole for mounting an external member, and a track body or a movable body formed of FRP jointed with the rolling part and the mounting part and forming the track member or the movable member, and the mounting part and the track body or the movable body have joint holes, opened in a direction orthogonal to a lamination direction of FRP reinforced fiber sheets S forming the track body or the movable body at a time of the joint, and can be jointed using jointing means. An external member can be securely mounted to the motion guide device formed of FRP.

An assembly including an inner component; an outer component; a tolerance ring, comprising an annular band and a plurality of projections projecting radially from the annular band, the tolerance ring being disposed between the inner component and the outer component; and a low friction layer provided radially inside or radially outside the annular band so as to enable sliding movement in an axial direction between the inner component and the outer component, wherein at least one of the inner component or outer component is profiled to transmit a radial load between the inner component and the outer component to appreciably prevent collapse of the projections.
