All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
As shown in fig. 1, the compact gyro dynamic calibration table according to the embodiment of the present invention includes a base 8, the base 8 is fixedly connected with a bearing inner support 10 through a bolt, the bearing inner support 10 is fixedly connected with a support bearing assembly 5 through a lock nut 11, the base 8 is fixedly connected with a stator of a motor 7 through a bolt, a rotor of the motor 7 is fixedly connected with a motor rotor base 1 through a bolt, an upper end of the motor rotor base 1 is fixedly connected with a table top transition piece 2 through a bolt, an upper end of the table top transition piece 2 is fixedly connected with a table top 6 through a bolt, and a lower end of the table top 6 is provided with an encoder 3.
In the present invention, the inner support 10 of the bearing is fixed to the base 8 by bolts, and the inner ring supporting the bearing assembly 5 is seated on the step of the inner support 10 of the bearing and fixed by the lock nut 11. The outer ring of the support bearing assembly 5 is pressed against the motor rotor base 1 via the table transition piece 2. The rotor of the motor 7 is fastened with the motor rotor base 1 through bolts, and the stator of the motor 7 is fixed on the base 8 through bolts. Wherein the back-to-back mounted angular contact ball bearings 5 comprise a pair of back-to-back mounted angular contact ball bearings, the so-called back-to-back mounting being the two thicker sides of the angular contact ball bearings are close together, the angular contact ball bearings have the advantages of back-to-back use: the load lines of the back-to-back paired bearings are separated from the bearing axis, and when the bearings are installed back to back, the load action center is positioned outside the central line of the bearings. The span of the force action point is larger, so the rigidity of the cantilever end is larger, when the shaft is heated and elongated, the clearance of the bearing is increased, and the bearing cannot be stuck and damaged; back-to-back mounted bearings provide a relatively rigid bearing arrangement and can withstand overturning moments. Can bear axial loads acting on two directions; the component force of the right bearings arranged back to back is upper right (lower right), and the component force of the left bearings is upper left (lower left), so that the two bearings are separated and can resist axial force in two directions without moving; the back-to-back installation can bear 2 times of radial component force, the intersection point of the two component forces is relatively close, the requirement on the deflection of the shaft is relatively low, and the shaft is not easy to deform under stress. The motor is arranged on the periphery of the bearing, namely, the motor is positioned in an inner space formed by the table top 6, the base 8 and the motor rotor seat 1, so that the size of the device is greatly reduced, the device can be used as a portable testing and calibrating device, and meanwhile, the compact structure ensures the advantages of quick start and quick stop of the gyro calibrating table.
The table-board transition piece 2 is fixed on the motor rotor base 1 by bolts, and the table-board 6 is fixed on the table-board transition piece by bolts. An encoder lock 4 is arranged in the center of the table top for connecting the encoder 3 and the table top 6 together for real-time feedback of the position state of the load.
When the testing system is used specifically, the angular rate gyroscope is fixed on the table top 6, the motor 7 is started, the motor rotor base 1, the table top transition piece 2 and the table top 6 rotate together with the rotor of the motor 7 as a whole, and the testing system can test the angular rate gyroscope at the moment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
