METHOD AND DEVICE FOR MEASUREMENT OF STICKING INTENSITY AT CONNECTED PART

PURPOSE:To measure the sticking intensity at a connected part, by applying the exciting force inclreasing with the time lapses to give vibrations to the connected part, measuring the degree of distortion caused to a memeber and detecting a sudden displacement. CONSTITUTION:When the rotary frequency of a variable speed motor 8 is gradually increased, the momentum transmitted through a flexible shaft 7 increases to increase the vibration of an exciter 6. Accordingly, a connected shaft 2 vibrates, and a connected part 3 also vibrates. The degree of distortion of a plate 1 which is caused by the vibration of the part 3 is detected by an attached semiconductor distortion gauge 10, and the output of detection is displayed at a meter 9 via an amplifier 11 and a rectifier 12. A sudden change of the degree of distortion at the part 3 emerges in the form of a change of the degree of distortion of a component member. This degree of distortion becmes an index that shows tha sticking intensity of the part 3. At the same time, the output signal of the gauge 10 is amplified and supplied to a synchro scope 21 to be displayed in the form of a load waveflorm. Thus backlash can be decided for the connected part.
