Blade balancing clamp and balancing method of blade interlocking rotor

Abstract

The invention discloses a blade balancing clamp and a balancing method of a blade interlocking rotor, the blade balancing clamp utilizes a balancing base and a balancing cover plate to axially limit and radially limit a whole disc of blades, and the adjacent blades are axially limited through a folded blade crown. According to the invention, the blades are prevented from moving axially and flying out in the radial direction when the unbalance amount inspection is carried out on the balancing machine, a wheel disc is not needed to carry out unbalance amount inspection, wheel disc balancing and blade balancing can be carried out separately and synchronously, a serial process is changed into a parallel process, the rotor assembling efficiency is improved, and when the positions of the blades need to be adjusted, the working efficiency is improved. And the positions of the blades can be directly changed on the balancing machine without using a whole-disc blade disassembling tool, so that the times of loading and unloading the balancing machine are reduced, the hoisting process of the rotor between the balancing machine and the assembling frame is also omitted, and the assembling efficiency of the blade interlocking rotor is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of rotor assembly, in particular, to a blade balancing fixture, and in particular, to a balancing method for a blade interlocking rotor, which adopts the above-mentioned blade balancing fixture. Background technique [0002] Large aero-engine turbines are usually made of blades and discs separately, which need to be balanced after being assembled into a rotor. The routine process is roulette assembly - roulette balance - blade roulette assembly - blade roulette balance. When assembling the roulette, you need to know the unbalance of the components on the roulette in advance, and stagger the light points according to experience; before the blade is assembled, measure the weight moment, Arrange multiple blades in four quadrants according to the weight moment to make the weight moment as uniform as possible. In fact, according to experience, the staggered light and key points and the four-quadrant cros...
