The invention discloses a balance block for flexible rotor dynamic balance and a de-weight balance method. The balance block is wholly in a hollow thin-wall shaft structure, and comprises a connectionsection for fixing to a transmission shaft and a de-weight section subjected to de-weight processing to meet dynamic balance requirement of the transmission shaft. The de-weight section comprises four arc teeth uniformly distributed in the circumferential direction. A U-shaped groove is formed between two adjacent arc teeth. The arc teeth and the U-shaped grooves are uniformly and alternately distributed in the circumferential direction of the balance block. The balance block is simple in structure and convenient to use, can realize quick assembly and disassembly with the transmission shaft;after de-weight processing of the de-weight section of the balance block, the balance block can meet balance requirement of a rotor; and the balance block is suitable for a rotor shaft subjected to surface treatment, is simple to debug, and is high in processing and installation efficiency.
Description
technical field [0001] The invention relates to the field of rotor dynamics, in particular to a balance weight used for dynamic balancing of a flexible rotor. In addition, the present invention also relates to a weight-removing and balancing method using the above-mentioned balancing weight. Background technique [0002] The rotor of an aero-engine is an important part of an aero-engine. An unbalanced aero-engine rotor will cause engine vibration, generate noise, accelerate bearing wear, shorten the service life of the engine, and cause destructive accidents in severe cases. For this reason, the rotor must be balanced so that the amplitude of the mechanical vibration it generates falls within the allowable range. [0003] The new generation of aero-engines pursues high performance and high thrust-to-weight ratio, and the speed can reach more than 20,000 rpm. The requirements for dynamic balance of flexible rotors are getting higher and higher. Patent CN 105867307A disclose...
