Abstract

PURPOSE: To increase safety and reduce the weight of the device without enforcing parts by electrically detecting the unbalanced vibration of blowing vanes and automatically stopping the motor through breaking the circuit of the motor.
CONSTITUTION: A rotary shaft 8 is supported by a ball bearing 12 in its middle. A resistance wire strain gauge 16 as an electric detector is buried in the cylindrical metal 15 along the axial direction. When the unbalance of the blowing vanes 5 causes abnormal vibration, flexural deformation takes place in the rotary shaft 8 due to the whirling motion of the vanes 5 to cause related flexural deformation of the cylindrical metal 15 struck by the rotary shaft 8. Above deformation effects tension and pressure upon the resistance wire strain gauge 16 to increase or decrease the resistance value of the gauge 16. This resistance change is turned into electric change to operate a relay 19, cutting the power to the motor 4
