Abstract
PURPOSE: To prevent a testing device from being destroyed owing to abnormal vibration, by measuring vibration by rotating an engine crank shaft at a rotational frequency lower than an idling frequency.
CONSTITUTION: Testing device 5 consists of frame 6, clamping device 7, engine weight 8, driver 9, the 1st and 2nd vibration measuring devices 10 and 11, etc. In this constitution, engine 2 is carried in by conveyor 1 and automatically positioned on palette 4 of setting table 12, and a prescribed limit switch and hydraulic cylinder set engine 2 at an inspection position fully automatically. Nect, motor 21 rotates crank shaft 28 via coupler 23 at 150W300r.p.m. first and vibration is measured by vibration sensors 32 and 34. If no abnormality occurs, it is measured at 600W800r.p.m. and then 1,300W2,000r.p.m. Consequently, since it is measured at the rotational frequency lower than an idling frequency, the destruction of the device due to abnormal vibration is prevented.
