Technical Field
[0001] The utility model relates to the technical field of rotor counterweights, in particular to an aero-engine rotor balancing counterweight device. Background Art
[0002] An aviation rotary engine (usually referred to as a rotary engine or rotary engine) is a type of engine that uses a rotating piston. It is different from a traditional reciprocating piston engine. Its working principle is based on a triangular rotor rotating in an elliptical combustion chamber to complete the four stages of intake, compression, combustion and exhaust.
[0003] In rotary engines, rotor counterweighting is a crucial design consideration. Because rotary engines operate on different principles and structures than traditional reciprocating piston engines, the design of the rotor counterweight has a direct impact on the engine's balance, stability, and performance. During installation, the counterweight must be adjusted to the rotor's requirements and must be sufficiently stable. However, existing counterweights, when threaded into place, can easily loosen due to vibrations generated by the rotor's continuous rotation, resulting in unstable counterweight installation.
[0004] Therefore, it is necessary to design an aero-engine rotor balancing weight device to solve the above problems. Utility Model Content
