or 20
.The present invention is not when affecting small torque calibration device dynamic property, counter weight device is adopted below calibration beam, solve gyroscope and the vibrative problem of small and special electric machine that small torque calibration device test rotates with the speed of (30000 ~ 80000) r/min, have structure simple, design advantage that is ingenious, good stability.
Description
Technical field
The present invention relates to a kind of small torque calibration device, particularly one is based on indifferent equilibrium principle,
The Standard Beam that High Rotation Speed small and special electric machine vibrates can be prevented.
Background technology
Small torque calibration device, for the torque calibration to the components and parts such as gyroscope, micro motor.In Inertial navigation platform, microthrust test is a core component, is the motor of a High Rotation Speed, and main shaft output torque is in mNm level and following, and some is even in μ Nm level.In modern torque calibration technology, have torque standard device above, but be still a difficult problem to international moment of torsion circle that is aligned in of mNm level and following slight torque in Nm level, calibration difficulty is high.
During gyroscope work, rotate with the speed of (30000 ~ 80000) r/min.Therefore, in order to calibrate its torque characteristics, being arranged in small torque calibration device and being carried out testing experiment.But in test due to gyroscope High Rotation Speed, can dither be produced, measuring equipment cannot be worked.
Summary of the invention
The present invention will solve in the detection calibration process of gyroscope or small and special electric machine slight torque, easily there is the technical matters of dither, and a kind of anti-dither beam for small torque calibration device is provided, when not destroying small torque calibration device indifferent equilibrium, increase the quality of beam, thus solve the problem that small torque 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 torque calibration device, comprises calibration beam, balancing weight, is characterized in: calibration beam is connected balancing weight by hook with thin steel band shell fragment.
Balancing weight and thin steel band shell fragment are positioned at the blade vertical galassing face of calibration beam, and with blade on same straight line.
Thin steel band shell fragment is thick is 10
or 20
.
Beneficial effect of the present invention is: when not affecting small torque calibration device dynamic property, counter weight device is adopted below calibration beam, solve gyroscope and the vibrative problem of small and special electric machine that small torque calibration device test rotates with the speed of (30000 ~ 80000) r/min, have structure simple, design advantage that is ingenious, good stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is balancing weight and thin steel band shell fragment syndeton schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, shown in 2, the anti-dither beam for small torque calibration device of the present invention, comprises calibration beam 1, balancing weight 4, hook 3 and thin steel band shell fragment 2.
Calibration beam 1 is connected balancing weight 4 by hook 3 with thin steel band shell fragment 2.Balancing weight 4 and thin steel band shell fragment 2 are positioned at the blade vertical galassing face of calibration beam 1, and with blade on same straight line.Thin steel band shell fragment 2 is thick is 10
or 20
.
For preventing the weights hangar system of dither, Fig. 1 central bearing point 5 is blade center, is the rotation center of beam, and blade and edge bearing are linear contact lay, and all beams and Weighting system all wt all act on fulcrum 5.
Fig. 1, in 2, balancing weight 4 weight " mg " is acted on calibration beam 1 by hook 3 and thin steel band shell fragment 2, and key is also can around fulcrum.This structural design scheme " mg " increases the pressure of blade to edge bearing, due to the elasticity that thin steel band shell fragment 2 is very little, through blade same space line be connected with device " mg " do not participate in the dynamic process of apparatus structure, so " mg " can not form loss to device performance, but add the pressure of knife to edge bearing, effectively prevent vibration from interfering.
The present invention should increase the quality of small torque calibration device beam, can not affect the indifferent equilibrium of beam simultaneously.Gain in weight, make that blade makes knife to the increase of edge bearing pressure, edge bearing does not misplace, device could normal work, and its principle makes knife increase vibration proof interference to edge bearing pressure, and the constant design concept of the original performance of device be independently heavy burden heavy " mg " with 10
or 20
thin steel band shell fragment, is connected with device through blade same linear space in the heavy face of blade vertical.
