Abstract:
     The invention discloses the laser testing method of the roller bearing vibration displacement. Equip the bearing on the spin axis of the test bed; makes use of the reflection of the laser through the bearing surface to arrive the PSD sensor surface; the PSD position sensor gives the facula position. The internal loop and the main axis of the bearing can be viewed as the rigid body because the radial force carried by the external loop of the bearing. When the spin axis spins, the inner and the external loops and the roller bring about the vibration and reflect the displacement s of certain point of the bearing surface by the PSD sensor. The invention has simple structure, clear principle and high precision.
