Abstract:
System and apparatus for moving a tubular between a substantially horizontal position and an upward angled position, e.g. substantially vertical position. The apparatus comprises a base, and a boom pivotally attached to the base about a horizontal boom pivot axis between a substantially horizontal position and an upward angled position, e.g. substantially vertical position. A boom pivot drive is mounted on said base and adapted to pivot the boom. A tubular gripper is attached to the boom and adapted for gripping the tubular. The boom pivot drive comprises a central gear wheel that is rotatable mounted on the base about a central gear wheel axis parallel to the horizontal boom pivot axis, which central gear wheel is connected directly or via a transmission to the boom. One or more drive gear members are each rotatable mounted on the base and each rotatable about a corresponding drive gear member axis, meshing with the central gear wheel. One or more motors connect to said drive gear members and allow to pivot the boom.
Abstract:
Die Erfindung betrifft einen Antrieb zur motorischen Verstellung eines Verstellelements (1) eines Kraftfahrzeugs mit einem Antriebsmotor (2) und einem dem Antriebsmotor (2) nachgescltalteten Vorschubgetriebe (3) zur Erzeugung von Antriebsbewegurtgen, wobei der Antriebsstrang (4) des Antriebs nicht selbsthemmend ausgestaltet ist, so dass der Antrieb im montierten Zustand eine manuelle Verstellung des Verstellelements (1) erlaubt, der der gesamte Antriebsstrang (4) weitgehend schlupffrei folgt. Es wird vorgeschlagen, dass im Antriebsstrang (4) des Antriebs eine Überlastkupplung (5) angeordnet ist, so dass im montierten Zustand eine manuelle Verstellung des Verstelleleznents (1) bei einer Betätigungskraft auf den Antrieb oberhalb einer Grenz-Betätigungskraft das Auskuppeln der Überlastkupplung (5) auslöst.
Abstract:
A pusher for a movable furniture element, in particular a revolving door, a piece of furniture having a body (1) with at least one wall (2) or a plurality of walls (2-6), is characterised in that the pusher is designed in such a way that it can be integrated into one of the walls (2-6) of the piece of furniture.
Abstract:
The invention relates to a drive unit for automatically actuating a vehicle door, especially the tailgate of a motor vehicle. The inventive drive unit (4) can be connected to the vehicle door (1) or a transmission device (6) via an output shaft (5), said transmission device (6) performing a pivoting movement that corresponds to the pivoting movement of the vehicle door (1). The drive unit (4) comprises at least one first sensor unit (7) that can be connected to an electronic evaluation unit (21) and detects the respective angular position of the vehicle door (1). The aim of the invention is to make use of the advantages of an incremental measurement of the position of the vehicle door (1) without having to wait for the vehicle door (1) to reach its final position to be able to recalibrate following a power outage. Said aim is achieved by dividing the entire pivot angle (α) of the vehicle door (1) into at least three successive zones (pivot angle ranges) (α1-α4), the individual pivot angle ranges (α1-α4) being determined by a first sensor unit (7) that detects absolute values. The pivot angle of the vehicle door within the individual zones (α1-α4) is then detected with the aid of a second sensor unit (8) which encompasses at least one incremental measuring transducer.
Abstract:
The invention relates to a drive mechanism comprising a drive shaft (6) which can be connected to a motor and swivels a vehicle door or vehicle hood (2) that is connected in a torsion-proof manner to a hinge loop (3) about a hinge pin (4). In order to arrange the drive mechanism and the hinge loop (3) in a very compact manner, a planetary gear that is integrated into the hinge loop (3) is used as a drive mechanism (5). The drive shaft (6) of the drive mechanism (5) is formed by the support shaft of the sun wheel (7) while the internal gear (12) of the planetary gear (5) is formed by the end of the hinge loop (3), which is located on the side facing the hinge pin. The support shafts (18) of the planet wheels (10) are mounted inside at least one support element (14, 15) that is placed lateral to the hinge loop (3) and can be connected in a fixed manner to the vehicle body. Preferably, the at least one support element (14, 15) is embodied as a bearing block (13) upon which the hinge loop (3) is pivotally arranged.
Abstract:
Die vorliegende Erfindung betrifft eine Sensoreinheit (1) zur Positionsbestimmung eines motorisch angetriebenen Tores, mit einem Positionssensor (6) und einer Getriebestufe zur Verbindung des Positionssensors (6) mit der Antriebswelle (3) des Tores, wobei die Sensoreinheit (1) ein eigenes Gehäuse (4,14) aufweist, so dass sie unabhängig von der Antriebseinheit (2) des Tores montiert werden kann.
Abstract:
Actuator has drive shaft (11) connected to bonnet and connected by transmission to rotor (27) of electric drive motor. Drive shaft can also be driven by stored power source independently from motor. Transmission has gear (35) with meshing gear (37). One part of circumference of first gear has no teeth to allow free movement in which auxiliary power source is connected. Auxiliary power source can be coil spring (39).
