A pinion to be fitted on a turbine axis of an internal combustion engine, wherein said pinion is made in a single piece, equipped with an axial thread to screw it on said axis of the turbine, wherein an axial end of the pinion integrates/defines a disc spring.

A self-locking nut includes a main-nut body and a deformable-nut body. The main-nut body has a recess leading into an interior threaded bore forming x turns of an internal thread therein. The deformable-nut body has an outer flange and an interior threaded nore forming y turns of an internal thread therein. The outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess. A ratio of x:y is about 2:1.

A fixing device has two threaded rings (10, 12), and aa membrane (14) held between them that is an integral part of this pair of rings (10, 12) and is kept at a distance from the rings (10, 12) by introduced slots (16, 18, 24, 26), rectilinear in a unmounted state. The slots open to the outside. By resting against only partially annularly extending webs (20, 22) and having a clamping bolt (30) usable to adjust the axial distance between the and passing through the membrane (14) between two adjacent webs (20, 22), in the unmounted state the membrane is oriented in an undeformed manner in parallel to the rings (10, 12) and in a mounted state it is moved between the webs (20, 22) in a deformed state in the direction of at least one of the rings to at least partially form a slanted or arc course, as soon as the distance (a) between a pair (10, 12) of rings (10, 12) is reduced by the clamping bolt. The clamping bolt (30) passes through adjacent slots (16, 18, 24, 26) separated from the membrane (14).

A robot hand to hold a substrate, which includes a base body, a blade defining a holding position for holding the substrate and attached at a base part to the base body, and a differential screw having a center axis perpendicular to a principal surface of the substrate existing at the holding position and configured to attach the base part of the blade to the base body. The differential screw includes a first threaded part having a first pitch, a second threaded part having a second pitch different from the first pitch, and an intervening member coaxially having a third threaded part to be threadedly engaged with the first threaded part, and a fourth threaded part to be threadedly engaged with the second threaded part. The first threaded part is provided to the base body, and the second threaded part is provided to the base part of the blade.

A self-locking nut includes a main-nut body and a deformable-nut body. The main-nut body has a recess leading into an interior threaded bore forming x turns of an internal thread therein. The deformable-nut body has an outer flange and an interior threaded bore forming y turns of an internal thread therein. The outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess. A ratio of x:y is about 2:1.
