Textile machine twine or spinning frame spindle has top-mounted vibration detector linked via a computer and electronic control system to correctional base bearing

摘要

A twine or spinning frame has a spindle surrounded by first and second concentric tubes that are separated at the neck by a bearing bush and electronic deflection measuring system. The electronic detector is coupled to an electronic control system that issues corrections to a piezo electric actuator associatediated with the spindle base bearing. A twine- or spinning frame has a bench with a spindle shaft supported by a central base bearing within a centring tube located within a second coaxial centring tube with reduced radius at half-length. The resulting shoulder supports a dampening spiral located between the centring tube and the spindle housing. A second dampening spiral is located below the shoulder in the annular gap between the first and second tubes and rests against the base bearing. The top end of the second spiral rests against the spindle housing neck bearing bush (9). An electronic measuring system (16) is located in the area below the bush neck bearing. The system detects the distance, frequency and deflections in this zone and converts these into electrical signals that are compared by a data processing system (15) with known target values. The differences are used as correctional values by the electronic control system (19) that is coupled to a piezo-electric actuator (14) associated with the base bearing (10) and acting on the spindle shaft (6).
