Measurement hub sleeve to monitor the loading on machine shafts, and the like, is in two half-shells with flanges and fitted with the data transmission unit, to be fitted rapidly and easily to the shaft without force flow interruption

摘要

The hub (1), to measure the loading on shafts (4) and the like, is a sleeve composed of two half-shells (1a,1b;2a,2b) locked together in a release fitting to lock at the measured machine component. The hub carries monitors (7a-7c) to register torque and bending strains, for their values to be transmitted to an external evaluation unit The measurement sleeve and flanges (2a,2b) are divided centrally. The flanges are attached to the measurement sleeve by release mountings. The measurement sleeve has at least one slip ring to transfer the measurement data, or it has fittings (9,11,12) for telemetric data transmission. The measurement sleeve has slits bisecting the circumference at a zone near one of the flanges. The measurement sleeve has expansion measurement strips (7a-7c) to react to different conditions at the measurement point.
