Abstract

Die Erfindung betrifft einen Halter (21) für einen Schraubendreher-Einsatz (6).The invention relates to a holder (21) for a screwdriver insert (6).

Erfindungsgemäß findet in dem Halter (21) ein Antriebsteil (1) Einsatz, bei dem ein Torsionsabschnitt (7) gebildet ist mit einer kurvenförmigen oder teilkreisförmigen Kontur, über die ein gleichmäßiger Spannungsverlauf ohne Spannungsspitzen und eine Herbeiführung einer gewünschten Torsionssteifigkeit gewährleistet werden kann. Der Schraubendreher-Einsatz (6) sowie das Antriebsteil (1) sind jeweils von einem Endbereich eines Aufnahmeteils (25) aufgenommen. Eine Außenhülse (27) ist derart mit dem Aufnahmeteil (25) verbunden, dass zumindest eine axiale Position der Außenhülse (27) gegenüber dem Aufnahmeteil (25) gesichert ist. Zwischen dem Torsionsabschnitt (7) und dem Übertragungsquerschnitt (5) ist ein zylindrischer Teilbereich (9) angeordnet. Die Außenhülse (27) besitzt einen Endbereich, der einen kleinen Spalt (36), eine Spiel- oder eine Übergangspassung mit der Mantelfläche (35) des zylindrischen Teilbereichs (9) bildet. Auf diese Weise erfolgt eine Abstützung der Außenhülse gegenüber dem Antriebsteil (1).

Figure imgaf001
According to the invention, a drive part (1) is used in the holder (21) in which a torsion section (7) is formed with a curved or part-circular contour, via which a uniform voltage curve can be ensured without voltage peaks and a desired torsional stiffness is achieved. The screwdriver insert (6) and the drive part (1) are each received by an end portion of a receiving part (25). An outer sleeve (27) is connected to the receiving part (25) such that at least one axial position of the outer sleeve (27) relative to the receiving part (25) is secured. Between the torsion section (7) and the transmission cross section (5) a cylindrical portion (9) is arranged. The outer sleeve (27) has an end portion which forms a small gap (36), a play or a transition fit with the lateral surface (35) of the cylindrical portion (9). In this way, a support of the outer sleeve relative to the drive part (1).
