摘要:
Ein Kugelgewindetrieb umfasst eine Spindelmutter (21), eine Gewindespindel und ein Halteelement (23). Das Halteelement (23) ist durch eine die Gewindemutter (21) in einem Endbereich aussen umgreifende Vorkragung (24) formschlüssig spielfrei mit der Gewindemutter (21) verbunden. Die Gewindemutter (21) und das als Kraftübertragungsglied fungierende Halteelement (23) werden bei der Fertigung zunächst positionsgenau angeordnet und anschliessend durch eine formschlüssige, insbesondere spielfreie, Verbindung, insbesondere durch Verstemmen, Verpressen, Clinchen oder andere Verformprozesse, verbunden.

A nut (110) and lead screw (104) assembly is disclosed. The nut (110) includes a plurality of flexible fingers (112) for adjusting the engagement of a threaded or unthreaded portion of the nut with corresponding threads (106) of a lead screw. The engagement between the nut (110) and the lead screw (104) is adjusted by installing at least one radial compression member (114) into a circumferential groove (116) formed in the outer surface of the flexible fingers (112).

The invention concerns a desmodromic mechanism comprising: a) means for transmitting (13) motion connected to an intermediate element (4, 5) and supported by it; b) a primary cam (2) in permanent contact with each of the transmitting means (13); and c) a secondary cam (11, 12) in permanent contact with each of the transmitting means (13). This mechanism is characterised in that the transmitting means (13) have smooth contact surfaces with the cams (2; 11, 12) in such a way that they ensure a permanent and simultaneous contact with the primary (2) and secondary (11, 12) cams; the primary cam (2), the secondary cam (11, 12) and the intermediate element (4, 5), are assembled to one another so as to compulsorily move in rotation and/or linearly relative to one another and at differential speeds invariable for all the positions of the mechanism.

Herein disclosed is a motion transforming apparatus, comprising first and second rotation shafts (51, 52) each formed with crank shaft portions (53-55, 56-58), a plate assembly (60) constituted by rotation plates (61A, 61B, 61C) each formed with teeth (62a) and cranked through bores (61e, 61f) respectively having the crank shaft portions of the rotation shafts (51, 52) received therein, a toothed rail (70) having teeth (72a), and a plate assembly housing (80) relatively movable along the toothed rail (70), wherein the first rotation shaft (51) is driven to rotate the rotation plates (61A-61C), and each of the rotation plates has an untoothed portion (68) connected to the toothed portion (62) of each rotation plate (61A - 61C) to be spaced from the toothed portion (72) of the toothed rail (70) and to have the toothed portions of the rotation plates closer to the second rotation shaft (52) than the first rotation shaft (51). The toothed portion (62) of each rotation plate is thus deviated from the second rotation shaft (52) and held in mesh with the toothed rail (70) in the vicinity of the first rotation shaft (51), thereby reducing a moment which tends to rotate the plate assembly housing (80) around the first rotation shaft (51) so as to lift up the leading end of the plate assembly housing (80).
