Title: High speed spindle with critical damping - gives indication when metallic contact occurs between shaft and bearings by amplified current initiating alarm
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: B65H54/74
Filed: 1979-08-31
Abstract: For critically damped bearings, the spindle is housed in the bearing part by interposition of elements with a low module of elasticity such as rubber. To avoid mounting and assembly faults, damage and wear of the flexible elements when spindles run at more than 3,000 meters per min. the spindle, e.g. winding synthetic fibres, stationary bearing part (11) are electrically isolated from one another, and form an electrical circuit in common with a voltage source and signal transmitter (20). Any metallic contact between shaft, roller bearing and bearing housing is immediately indicated,allowing the drive to be switched off. The coiling spindle (1) has its ends connected to an amplifier (20) through sliding contacts (15,16) and leads (21,23). The fixed mounting part (11) is coupled to the voltage source via lead (22) also connected toe amplifier (20). An output signal (24) appears when current flows through the leads (21,22,23). This occurs when the rubber elements (8,9,10) are wrongly mounted so that the drive slips or a metallic contact is established between the outer rings of the roller bearings (5,6,7) and the fixed section (11) by metallic impurities. This output signal (24) can be used to release an optical or acoustic alarm or operate a relay (29) and switch (30) for cutting out a drive roller motor (13).
