Embodiment Construction

[0028] The torque limiting device has a stem 3 made of steel which has a projection or step 16 on which the first torque transmission body 1 is supported. The torque transmission body 1 , manufactured for example as a plastic injection-molded part, metal die-cast part, milled part, precision cast part, is connected in a rotationally fixed manner to the stem 3 and does not change its axial position relative to the stem 3 . The first torque transmission body 1 has a torque transmission tooth with an inclined side 4 and an opposite steep side 6 . In this exemplary embodiment, a washer 17 is supported on the step 16 , and the torque transmission body 1 is in turn supported on the washer 17 . The torque transmission body 1 has a cavity with a hexagonal inner contour that is open toward the washer 17 , in which cavity a hexagonal coupling disc 20 made of steel is accommodated. The hexagonal coupling disk has a polygonal inner contour which is filled by the polygonal outer contour s...

Abstract

The invention relates to a torque-limiting device having two torque transfer bodies (1, 2), which, as a consequence of oblique flank contact during relative rotation about an axis (A), can be moved relative to each other in the direction of said axis (A) against the restoring force of a spring element (8), which is supported on a shoulder (10) of an abutment (9), the position of which shoulder isset during calibration of a limiting torque. By means of a method according to the invention, the torque-limiting device is calibrated by applying a predefined force (F1) to the spring element (8). The resulting spring length defines the axial position of the shoulder (10) of the abutment (9), which axial position is irreversibly fixed.

Description

technical field [0001] The invention relates to a torque limiting device having two torque transmission bodies which, during relative rotation about an axis, are able to counteract a restoring force of a spring element by virtue of inclined sides abutting against a direction along the same axis. To move relative to each other, the spring element is supported on a shoulder of the support which defines the position when the limit torque is calibrated. [0002] Furthermore, the invention relates to a calibration method for calibrating a torque transmission device having two torque transmission bodies which, during relative rotation about an axis, bear against the The directions along the same axis are displaceable relative to each other counter to the restoring force of the spring element, which rests on a shoulder of the support that defines the position when the limit torque is calibrated. [0003] Furthermore, the invention relates to a plurality of screwing tools which each ...
