Angle measuring device

Abstract

The invention relates to an angle-measuring device comprising a stator (1) and a rotor (2), wherein said rotor (2) is arranged rotatably relative to the stator (1) about an axis (A) in the circumferential direction (U). The rotor (2) comprises a shaft (2.1) on which a code disc (2.2) is mounted for rotation therewith. The stator (1) comprises a body (1.3, 1.3 ', 1.3 ") and a scanner (1.2) for scanning the code disc (2.2). For vibration damping, the angle-measuring device comprises a pendulum mass (1:42, 1:42 '; 1:42 ") connected with the body (1.3, 1.3', 1.3 '). The pendulum mass (1:42, 1:42 '; 1:42 ") is deflectable relative to the body (1.3, 1.3', 1.3") with a directional component parallel to the circumferential direction (U).

Description

technical field [0001] The invention relates to an angle measuring device according to claim 1 . Background technique [0002] Angle measuring devices, often also referred to as rotation generators, are used to measure the rotational movement of a rotatably mounted body via one or more revolutions. In this case, the rotational movement is detected incrementally or absolutely. In combination with a rack and pinion, or with a threaded spindle, linear motion can also be measured with an angular measuring device. [0003] Such angle measuring devices are often used in combination with electric motors. In order to compensate for alignment errors or axial misalignments between the mounted shaft of the angle measuring device and the associated electric motor, compensating couplings are often used. It can be arranged between the shaft of the angle measuring device and the electric motor, or it can be configured as a so-called stator coupling. A stator coupling elastically connec...
