Abstract
The invention relates to a high frequency vibration resistant beam used for a micro torque calibrating device. The high frequency vibration resistant beam comprises a calibration beam and a balancing block, and the calibration beam is connected with the balancing block through a hook and a thin steel band spring. The balancing block and the thin steel band spring are positioned in the plump heavy plane of the blade of the calibration beam, and are on a same line with the blade. The thickness of the thin steel band spring is 10mum or 20mum. The balancing block is adopted under the calibration beam without influencing the dynamic performance of the micro torque calibrating device, so the vibration problems of a gyroscope and a small and special electric machine of the micro torque calibrating device rotating at a test speed of (30000-80000)r/min are solved; and the high frequency vibration resistant beam has the advantages of simple structure, ingenious design and good stability.
Description
Technical field
The present invention relates to a kind of small torsion calibration device, particularly a kind of based on the indifferent equilibrium principle,
Can prevent the Standard Beam of High Rotation Speed small and special electric machine vibration.
Background technology
Small torsion calibration device is used for the torque calibration to components and parts such as gyroscope, micro motors.In Inertial navigation platform, little gyro is a core component, is the motor of a High Rotation Speed, the main shaft output torque the mNm level and below, some in addition in μ Nm level.In the modern torque calibration technology, more than the Nm level torque standard device is arranged, but international moment of torsion circle that is aligned in of mNm level and following small moment of torsion is still a difficult problem, the calibration difficulty is high.
During gyroscope work, with the speed rotation of (30000～80000) r/min.Therefore, in order to calibrate its torque characteristics, it is installed in carries out testing experiment on the small torsion calibration device.But in test because the gyroscope High Rotation Speed can produce dither, measuring equipment can't be worked.
Summary of the invention
The present invention will solve in the detection calibration process of gyroscope or the small moment of torsion of small and special electric machine, the technical matters that dither easily occurs, and provide a kind of anti-dither beam for small torsion calibration device, in the situation that do not destroy small torsion calibration device indifferent equilibrium, increase the quality of beam, thereby solved the problem that small torsion calibration device test high-speed electric expreess locomotive class test specimen produces dither.
For achieving the above object, technical scheme of the present invention is: a kind of anti-dither beam for small torsion calibration device, comprise calibration beam, balancing weight, and be characterized in: the calibration beam is by linking up with and being connected steel band shell fragment connection balancing weight.
Balancing weight and thin steel band shell fragment be positioned at the calibration beam blade vertical galassing face, and with blade on the same straight line.
Thin steel band shell fragment is thick to be 10
Or 20
Beneficial effect of the present invention is: in the situation that do not affect small torsion calibration device dynamic property, below the calibration beam, adopt counter weight device, solve small torsion calibration device test with gyroscope and the vibrative problem of small and special electric machine of the speed rotation of (30000～80000) r/min, had advantages of simple in structure, ingenious, the good stability of design.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is balancing weight and thin steel band shell fragment syndeton schematic diagram.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
Such as Fig. 1, shown in 2, the anti-dither beam for small torsion calibration device of the present invention comprises calibration beam 1, balancing weight 4, hook 3 and thin steel band shell fragment 2.
For preventing the counterweight counterweight hangar system of dither, Fig. 1 central bearing point 5 is the blade center, is the rotation center of beam, and blade is that line contacts with edge bearing, and all beams and Weighting system all wt all act on the fulcrum 5.
Fig. 1, in 2 balancing weight 4 weight " mg " by link up with 3 and thin steel band shell fragment 2 act on the calibration beam 1, key is also can rotate around fulcrum.This structural design scheme " mg " increases blade to the pressure of edge bearing, because the elasticity that thin steel band shell fragment 2 is very little, through blade same space line link to each other with device " mg " do not participate in the dynamic process of apparatus structure, so " mg " can not form loss to device performance, but increased the pressure of knife to edge bearing, effectively prevented the vibration interference.
The present invention should increase the quality of small torsion calibration device beam, can not affect the indifferent equilibrium of beam simultaneously.Gain in weight, increase does not misplace knife, edge bearing to edge bearing pressure to make blade, and device could work, and its principle is to make knife increase vibration proof to edge bearing pressure to disturb, and is that independently heavy burden weighs " mg " with 10 and install the constant design concept of original performance
