Use the utility model to measure bear vibration, can be divided into four steps: the first step is installed, measured bearing 8 is placed in the chuck 3, promoting platform 51 by loading and unloading cylinder 6 first moves, when platform 51 moved, measured bearing 8 was set on the air plug gauge 21 gradually, until platform 51 contacts with limit sensors 12, at this moment, measured bearing 8 has been in place.
Second step loads, and then unloads carrier gas cylinder 7 and discharges, and under the effect of loading spring 72, push rod 71 advances towards measured bearing 8, loads seat 716 and guarantees that the direction that push rod 71 advances is not offset.Push rod 71 advances in the process, and cylinder 713 passes the first through hole 33 on the chuck 3, holds out against the outer ring of measured bearing 8, realizes axially loading, and the loading force that axially loads is determined by loading spring 72.Then gauge head 9 descends, and contacts with the outer ring of measured bearing 8, and at this moment air plug gauge 21 starts, and drives the bearing inner race rotation, finishes the measurement of a point of bearing outer ring.
The 3rd step changed a little, finished after the measurement of a point, unloaded the loading of carrier gas cylinder 7, and piston rod is toward reclaiming slightly, so that the outer ring of cylinder 713 and measured bearing 8 is separated.Changed a little by air plug gauge 21 measured bearings 8 that rotarily drive own, change a little and controlled by the time.Thereby the rotation by means of stepper motor of comparing drives the rotation of axial thrust head and finishes changing a little of bearing, and structure is simplified greatly, also avoids loading spring to produce simultaneously and reverses, and has increased the stability that bear vibration is measured.Change to after the position that needs, unload carrier gas cylinder 7 and discharge, the cylinder continuation relies on the elasticity of loading spring to push against the outer ring of measured bearing, realizes axially loading, and then can finish again the vibration survey of a point.
The 4th step was changed face, after three point measurements on face of measured bearing are complete, unload the loading of carrier gas cylinder 7, piston rod is toward reclaiming, and then loading and unloading cylinder 6 is with platform 51 past recovery, drive measured bearing 8 and withdraw from air plug gauge 21, then change face cylinder 5 and start, drive chuck 3 Rotate 180 degree, while measured bearing 8 is the Rotate 180 degree also, repeat again the front first to third step, can finish the measurement of three points on another face of measured bearing.
All measure on two faces of measured bearing complete after, bear vibration is also just measured complete.
Referring to Fig. 6, the utility model unloads the piston rod of carrier gas cylinder 7 toward reclaiming when power cut-off, drive push rod toward reclaiming, so that cylinder 713 leaves the outer ring of measured bearing 8.Toward reclaiming, so that chuck 3 withdraws from air plug gauge 21, then drag hook 74 down rotates loading and unloading cylinder 6 with platform 51, the end of catching on web joint 714, and at this moment unloading carrier gas cylinder 7 can discharge.Because the effect of drag hook, thrust disc 712 can not recover and hold out against for a long time chuck 3 because of the elasticity of loading spring 2, the precision of avoiding changing the face cylinder is affected.
