Abstract

Die Erfindung betrifft eine Sicherheitsbremseinrichtung für die über einen Motor (4) mit angeflanschtem Hubgetriebe (3) antreibbare Wickeltrommel (8) eines Hebezeuges, welche bei überhöhter Senkgeschwindigkeit durch einen konzentrisch mit der Wickeltrommel (8) umlaufenden, und mit dieser reibschlüssig verbundenen Bremsring (12) ruckfrei zum Stillstand abgebremst wird, sobald der an einer zylindrischen Bremsfläche (23) des Hebezeuges anliegende Bremsring (12) blockiert wird. Um mit geringem Aufwand an Material und Kosten das Einschleifen und Einstellen des im Abschaltfall der Wickeltrommel notwendigen Bremsmomentes vor der Montage des kompletten Hubwerkes vornehmen zu können, wird erfindungsgemäß vorgeschlagen, die Bremsfläche (23) für den Bremsring(12) am Außenumfang einer Hubgetriebe (3) und Wickeltrommel (8) konzentrisch verbindenden drehstarren Kupplung (10) vorzusehen, an die Hubgetriebe (3) und Wickeltrommel (8) lösbar angeschlossen sind.

Figure imgaf001
The invention relates to a safety brake device for the winding drum (8) of a hoist which can be driven via an engine (4) with a flanged lifting gear (3) which rotates at an excessive lowering speed by a brake ring (12) concentric with the winding drum (8) and frictionally connected thereto ) is braked smoothly to a standstill as soon as the braking ring (12) resting against a cylindrical braking surface (23) of the hoisting gear is blocked. In order to carry out the grinding and setting of the necessary in the shutdown of the winding drum braking torque before assembly of the complete hoist with little effort on material and costs, the braking surface (23) for the brake ring (12) on the outer circumference of a screw jack (3 ) and winding drum (8) concentrically connecting torsionally rigid coupling (10) to be provided to the lifting gear (3) and winding drum (8) are detachably connected.
