It is with to be measured output shaft lateral location relative with side that described observation group is arranged on thermovacuum case top; Described observation group comprises observation camera lens and view window; Described observation camera lens is arranged on view window, and described observation camera lens comprises eyepiece, graticule, object lens, and described graticule is arranged between eyepiece and object lens, described graticule has the scale mark that two parallel.
Described thermovacuum case also comprises case lid and casing, and described casing is sealed by case lid, and described magnetic fluid seal driving axle is through case lid
Method of testing of the present invention is:
1, under normal temperature non-vacuum environment, by be measured clamping on the heavy type adjustment platform regulating support, to be measured output shaft and magnetic fluid seal driving axle are passed through spline joint.
2, adjust the observation camera lens of thermovacuum box top and side, make it possible to the output shaft observing to be measured clearly, then regulate observation camera lens respectively, in graticule two parallel scale marks are overlapped with output shaft sideline, just as the benchmark of subsequent adjustment.
3, the rotating shaft of rotating lever device, the gear driven tooth bar in rotating shaft moves, and by the plectrum on tooth bar, spline housing is allocated to transmission shaft side, throws off to be measured the connection between output shaft and transmission shaft and makes it be in free state.
4, seal thermovacuum case, test again when it reaches and tests temperature required and vacuum environment.
5, after temperature plateau, the deforming displacement amount of to be measured output shaft is observed by observation camera lens.
6, at thermal vacuum tank inner rotary lift adjustment screw rod or Level tune screw rod, movement and the rotation of heavy adjustment platform is controlled, to adjust the locus of to be measured.
7, keep the invariant position of scale mark in graticule, coordinate and regulate support move or rotate to be measured, until the distance between two scale marks to output shaft two sidelines is equal, now can think the dead in line of to be measured output shaft and magnetic fluid seal driving axle
8, the rotating shaft of rotating lever device, is allocated to be measured output shaft side by spline housing, reconnect to be measured output shaft and magnet fluid sealing axle, carry out follow-on test.
9, repetitive operation step 2 is to 8, can carry out to be measured performance test under different temperatures.
Mentality of designing of the present invention and advantage show:
By the impact of hot vacuum environment, to be measured can produce irregular deformation, thus has influence on the connection of to be measured output shaft and the outer proving installation of tank.
The present invention adopts observation camera lens observe and record the position of to be measured output shaft, and employing deflector rod device controls the de-conjunction between to be measured output shaft and magnetic fluid seal driving axle, adjusts to be measured the locus in thermal vacuum tank by regulating support.Therefore, the initial position of shot record to be measured output shaft is observed under normal temperature environment, then the connection of itself and magnetic fluid seal driving axle is thrown off by deflector rod device, allow to be measured Free Transform under hot vacuum environment, after temperature plateau, coordinate adjustment support by observation camera lens, to be measured output shaft is overlapped again with the axis of magnetic fluid seal driving axle, connect to be measured output shaft and magnetic fluid seal driving axle by deflector rod device again, carry out follow-up test.Also can be thrown off the connection of to be measured output shaft and magnetic fluid seal driving axle after to be measured loading is completed by deflector rod device, conveniently carry out the test of no-load characteristic.
Deflector rod device have employed the design concept of rack-and-pinion, rotate the rotating shaft be drawn out to outside thermal vacuum tank to move by the gear driven tooth bar in rotating shaft, plectrum is vertically mounted on tooth bar, and therefore, the rotary steerable of thermal vacuum tank outer shaft heats the movement of plectrum in vacuum tank.To be measured output shaft and magnetic fluid seal driving axle are set with splined shaft, spline housing is sleeved on splined shaft, plectrum is positioned at the both sides of spline housing, plectrum moves and drives spline housing to move toward magnetic fluid seal driving axle side, the connection between spline housing and to be measured output shaft upper spline axle can be thrown off, thus to be measured output shaft is freely discharged; In like manner, rotating shaft drives plectrum to move and drives spline housing to move toward to be measured output shaft side, spline housing can be engaged again with the splined shaft on to be measured output shaft.Deflector rod device can realize to be measured output shaft and throws off between magnetic fluid seal driving axle and be connected.
Support is regulated to realize five degree of freedom.To be measured is fixed on heavy adjustment platform, and setting to be measured output axial direction is x-axis, and direction and the vertical direction of vertical heavy adjustment platform are y-axis.In the lifting of thermovacuum case inner rotary lift adjustment screw rod lifting controllable adjusting screw(rod), three lift adjustment screw rods cooperatively interact and can realize support platform along the movement of y-axis, rotation around x-axis and z-axis;
Heavy adjustment platform is pressed in support platform by Action of Gravity Field, can realize the adjustment to heavy type adjustment platform by support platform.Heavy adjustment platform side is provided with two Level tune screw rods along the z-axis direction, rotates the flexible of Level tune screw rod controllable levels adjusting screw(rod), and two Level tune screw rods cooperatively interact and can realize the movement of heavy adjustment platform along z-axis, the rotation around y-axis.
To be measured along x-axis distortion and the connection not affecting splined shaft and spline housing around the rotation of x, therefore can not consider the distortion recurrence in this direction.
Lift adjustment screw rod is connected by self-aligning bearing with between support platform, and therefore rotating single lift adjustment screw rod by the impact of other two lift adjustment screw rods, just can not can adjust a plane by 3.Level tune screw rod adjusts platform by the oscillating bearing that two axis perpendicular are installed with heavy type and is connected, and oscillating bearing is sleeved on the axis of guide, therefore has and more regulates remaining.
Output shaft in thermovacuum case cannot carry out the demarcation of center line, therefore must adopt aid.The position of to be measured output shaft clearly can be observed by the observation camera lens of thermovacuum case top and side, two parallel scale marks are made in graticule just to overlap with output shaft sideline under normal temperature environment, the center of to be measured output shaft can be recorded, to be measured output shaft is generally rule distortion, therefore, after to be measured distortion completes, to be measured motion is controlled by regulating support, until in observation camera lens two parallel scale marks to output shaft sideline between distance equal, remain unchanged with the axial centerline under normal temperature original state under making output shaft hot vacuum environment.Cooperatively interacting of two observation camera lenses, the change in Observable to be measured output shaft four degree of freedom directions, meets and regulates requirement.
