Abstract

The invention relates to a gyro wheel rotation speed testing device and an air blowing system thereof. The air blowing system comprises an air blowing air path for blowing air on a gyro wheel to be tested to drive the gyro wheel to rotate. The air outlet end of the air blowing air path is provided with Laval nozzle structure. In the present invention, the air outlet end of the blowing air path adopts the Laval nozzle structure, because the Laval nozzle structure can effectively increase the high-pressure airflow to a higher rotational speed by using its own shrinking tube structure and expanding tube structure, so that it can be obtained High-speed airflow, which can reduce the requirements for the air supply source and reduce the cost. Moreover, the Laval nozzle structure can greatly increase the airflow speed, thereby expanding the speed test range of the speed test device using the air blowing system and improving its general test. performance.

Description

technical field [0001] The invention relates to a gyro wheel rotational speed testing device and an air blowing system thereof. Background technique [0002] The airfoil gyroscope of a certain product is a pneumatic gyroscope. When it is blown by high-pressure air, the gyroscope rotates rapidly. If the dynamic balance is not good, the gyroscope will generate a certain centrifugal force, which will drive the collision and friction between the mechanical structures, which will affect the product. performance indicators. [0003] In the dynamic balance test of the gyro wheel, the airfoil gyroscope needs to adjust the dynamic balance at a certain fixed speed, which requires the accuracy and reliability of the speed test. For example, in the measurement of the rotational speed of the airfoil gyroscope recorded in "Measuring and Testing Technology", Vol. 34, No. 9, 2007, most of the surface of the airfoil gyroscope is painted with white paint, and only a small part is painted wit...
