Balance-adjustable high-speed rotating blade and balance adjustment test method

Abstract

The invention discloses a balance-adjustable high-speed rotating blade and a balance adjustment test method. The balance-adjustable high-speed rotating blade comprises a balancing device and a self-balancing blade; an outer ring of a balancing ring of the balancing device is fixedly connected with the test box body through bolts, and the self-balancing blade is mounted on an inner ring of the balancing ring of the balancing device; according to the balance-adjustable high-speed rotating blade and the balance adjustment test method, the position and the number of the adjusting bolts on the self-balancing rotary table are simply adjusted, dynamic balance adjustment is conducted on the self-balancing rotary table before and after work, and the amount of unbalance caused by machining and mounting precision factors is thoroughly eliminated; the whole blades are connected into a whole in a mechanical connection mode of bolt connection, the defect that the aviation aluminum alloy material is poor in welding capacity is overcome, meanwhile, the mass of the whole blades is reduced, and centrifugal inertia force is reduced.

Description

technical field [0001] The invention relates to an adjustable and balanced high-speed rotating blade, in particular to a self-balancing adjustable high-speed rotating rain-eroded blade structure and a balance adjustment test method. Background technique [0002] The existing rain erosion test device has a low rotational speed, which can only simulate the possible rainfall environment during transportation and use, and cannot simulate the impact of rain on the surface of the test piece when the test piece is moving at high speed; the blades of the existing rain erosion resistance test machine Due to high-speed rotation will generate a large centrifugal inertial force, resulting in unstable blade movement; on-site dynamic balance adjustment cannot ensure the smooth surface of the blade, and the blade is made of high-strength and lightweight aviation aluminum alloy material, which is not easy to weld, so it is necessary to Design a mechanically connected blade structure.
