An Adaptive Installation Error Slip Ring Connecting Device

Abstract

The invention discloses a collector ring connection device adapted to installation errors by itself. The device comprises a collector ring, a universal joint and a revolving unit. The collector ring comprises a collector ring housing, a collector ring rotor shaft end, a keyway and a key. The collector ring rotor shaft end is connected with the universal joint through the keyway and the key. The universal joint is a two-section tight universal joint. A screw hole is formed in the upper section and lower section of the universal joint respectively. Two fastening screws are used to lock the collector ring rotor shaft end and the universal joint, and the revolving unit shaft end and the universal joint respectively. The revolving unit comprises a revolving body, a revolving unit shaft end, a keyway A and a key A. The revolving unit shaft end is a part of the revolving unit and is threaded with the revolving body, and is connected with the universal joint by the keyway A and the key A. By adjusting the fastening screws on the upper and lower sections of the universal joint, the distance error between the collector ring and the revolving unit can be compensated effectively, and by means of the deformation of the two-section tight universal joint itself, the angle error and the eccentricity error between the collector ring and the two-section tight unit can be compensated effectively.

Description

technical field [0001] The invention relates to the technical field of slip rings, in particular to a connection device for slip rings. Background technique [0002] At present, the foreign exchange ring and the rotary body at home and abroad generally adopt the connection form of shifting forks and grooves, which requires high precision for the distance, parallelism, and concentricity of rotation between the confluence ring and the rotary body, and poor manufacturability. [0003] The distance error will easily cause the extrusion or loosening of the shift fork and the groove, the angle error will cause the hidden danger of interference during the rotation process, and the severe eccentricity error will also lead to the destruction of the structure of the slip ring. [0004] Therefore, the industry needs a slip ring connection device that is self-adaptive to installation errors. Contents of the invention [0005] The present invention solves the problem of connection bet...
