Angle measuring device

Abstract

The invention relates to an angle measuring device with a stator (1) and a rotor (2), wherein the rotor (2) is relative to the stator (1) around an axis (A) along a circumferential direction (U ) are rotatably arranged. The rotor (2) has a shaft (2.1), on which a code disc (2.2) is fastened in a rotationally fixed manner. The stator (1) has a body (1.3; 1.3'; 1.3'') and a scanning device (1.2) for scanning the code disc (2.2). For vibration damping, the angle measuring device has a pendulum mass (1.42; 1.42'; 1.42'') connected to the body (1.3; 1.3'; 1.3''), the pendulum mass with a A direction component parallel to the circumferential direction (U) is deflectable relative to the body (1.3; 1.3'; 1.3'').

Description

Technical field [0001] The invention relates to an angle measuring device according to claim 1. Background technique [0002] Angle measuring devices, often also called rotation generators, are used to measure the rotational movement of a rotatably supported body via one or more revolutions. Here, the rotational movement is detected incrementally or absolutely. Combined with rack and pinion, or combined with threaded spindle, linear motion can also be measured using an angle measuring device. [0003] This angle measuring device is often used in combination with an electric motor. In order to balance the alignment error or axial misalignment between the supported shaft of the angle measuring device and the associated electric motor, compensation couplings are often used. It can be arranged between the shaft of the angle measuring device and the electric motor, or be configured as a so-called stator coupling. A stator coupling elastically connects the stator of the angle measuri...
