Abstract
A piston rod-less linear drive having a drive part adapted for motion in the longitudinal direction of the housing, such drive part being kinematically coupled by way of an entraining member running in a longitudinal slot in the housing with a guide slide arranged externally on the housing for sliding movement. For the connection between the entraining member and the guide slide a force transmitting part is provided which has a coupling socket in which the entraining member interlockingly fits by means of a coupling section in the longitudinal direction of the housing.
Claims15
A piston rod-less linear drive comprising an elongated housing which defines a receiving space for a drive part adapted to run in the longitudinal direction of the housing and being kinematically coupled by way of an entraining member with a guide slide, such entraining member extending through a longitudinal slot, such slide being arranged to be moved on a linear guide, which is attached to the housing, in the longitudinal direction of the housing, wherein the entraining member has a coupling section, which is formed by its outer end section, fitting between the guide slide and a force transmitting part attached to it, the entraining member being engaged, without any direct attachment to the guide slide by way of a plug connection, in an interlocking manner with a coupling socket, such coupling socket being formed on the inner side, facing the guide slide, of the force transmitting part.
