Locking system for a rotatable part

摘要

The invention relates to a locking system for a rotatable part, in particular in arrangements in which two parts which can be rotated in relation to each other, for example a die and a punch in a stamping apparatus, have to be aligned exactly in relation to each other. In order to provide a positionally accurate mechanical locking system with a simple design, the invention proposes that a gearwheel (3) having an end-side and/or axially effective toothing system (4) is connected to the rotatable part (2) fixedly in terms of rotation, and that at least one toothing segment (5a-5f) which can move to and fro in the direction of the axis of rotation and/or parallel to the axis of rotation of the gearwheel is arranged over the circumference of the gearwheel, wherein the teeth or gaps between the teeth of the toothing segment and gearwheel can be brought into engagement without play.

主权项

1. A locking system for a rotatable part, comprising:
a gear wheel having a tooth system and an axis of rotation, the gear wheel being one of connected and connectable to the rotatable part, the tooth system having a pitch; and a plurality of toothed segments arranged along a periphery of the gear wheel, each of the plurality of toothed segments is movable toward and away from the tooth system in a direction that is one of toward and away from the axis of rotation and parallel to the axis of rotation, wherein teeth and tooth spaces of e h of said plurality of tooth segments are engageable with the tooth system without play, wherein a first toothed segment of the plurality of toothed segments engages the tooth system at a first position of the gear wheel and each of the others of the plurality of toothed segments are engageable with the tooth system of the gear wheel at positions of the gear wheel that are offset from the first position by different non-whole number fractions of the pitch, and wherein each toothed segment of the plurality of toothed segments is adjustable in a circumferential direction around the axis of rotation of the gear wheel and is fixable in the selected position, whereby the offset between each of the plurality of toothed segments is adjustable.
