  • Bearing gap measuring device and method
    Patent number: 11221275
    Abstract: A bearing gap measuring device can measure a gap of a bearing to judge whether the bearing is damaged. The bearing gap measuring device includes: a pressure generating device configured to selectively supply a positive pressure and a negative pressure, which have a certain pressure, to an interior of a cylinder; and a displacement measuring device penetrating a cylinder head and applying a force to pull or push a piston by a sequential generation of a positive pressure and a negative pressure in the cylinder. In particular, the displacement measuring device includes a probe rod to contact with an upper face of the piston such that the probe rod is moved in a longitudinal direction to measure a height change amount of the piston.
