AI Technical Summary

Technical Problem

The installation of rotary brakes with magnetorheological media in limited space and difficult-to-access environments is often time-consuming.

Method used

A rotary brake design where the electrical contacting device automatically connects the stator-rotor assembly to the support structure during mechanical fastening, eliminating the need for separate electrical and mechanical fastening steps.

Benefits of technology

This design simplifies the installation process by allowing simultaneous mechanical fastening and electrical contacting, reducing installation time and complexity, especially in constrained environments.

Abstract

The invention relates to a rotary brake (1) comprising: a support structure (2); and a stator-rotor assembly (3) having a stator (4) and a rotor (5), wherein: an accommodating space (6) of the stator-rotor assembly (3) is formed between the stator (4) and the rotor (5) and a magnetorheological medium (7) is present in the accommodating space (6); the stator-rotor assembly (3) can be fastened, in a fastening position, to the support structure (2) by means of at least one fastening device (8, 9, 10) of the support structure (2) and, in the fastening position, the stator (4) is non-rotatably fastened to the support structure (2) and the rotor (5) is mounted for rotation relative to the stator (4); the stator-rotor assembly (3) comprises a coil (11) for generating a magnetic field (12) of variable field intensity and the rotary brake (1) comprises a contacting device (13) for bringing the coil (11) into contact with an electrical power supply (14); the fastening of the stator-rotor assembly (3), in the fastening position, to the support structure (2) necessarily establishes a connection position of the contacting device (13).
