Machine tool with telemetry monitoring system for tool shaft - uses sensor element attached to shaft and coupled to amplifier on outside of housing half shell enclosing shaft

摘要

The telemetry monitoring system uses a sensor element (3) attached to a reduced dia. shaft section (16), coupled to an amplifier and an antenna supported by the shaft, with a cooperating stationary transmission/reception antenna (8), coupled to an evaluation and display circuit. The larger and smaller dia. shaft sections (15, 16) are enclosed by a housing (28) comprising two half shells (29, 30) at a given distance from the sensor element. The amplifier is attached to the outside face of one of the shells. Both shells are balanced so that no imbalance force is exerted on the amplifier. USE/ADVANTAGE - For wear monitoring during machine operation. Suitable for relatively small machine tool rotating at high r.p.m.
