平衡配重

Balancing weights are precision components used to correct mass imbalances in rotating machinery like blade holders and rotors, ensuring smooth operation and preventing vibration.

技术定义与适配语境
典型 平衡配重 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

Balancing weights are specialized components designed to counteract mass imbalances in rotating assemblies such as blade holders and rotors. They are strategically placed to adjust the center of mass, minimizing centrifugal forces that cause vibration, noise, and premature wear. This is critical in high-speed applications like turbines, compressors, and fans to maintain operational stability, reduce mechanical stress, and extend equipment lifespan.

定义
Balancing weights are specialized components designed to counteract mass imbalances in rotating assemblies such as blade holders and rotors. They are strategically placed to adjust the center of mass, minimizing centrifugal forces that cause vibration, noise, and premature wear. This is critical in high-speed applications like turbines, compressors, and fans to maintain operational stability, reduce mechanical stress, and extend equipment lifespan.
工作原理
Works by adding or adjusting mass at specific radial positions on the rotating component to shift the center of mass toward the axis of rotation. This reduces the unbalance force (F = m × r × ω²), where m is mass, r is radius, and ω is angular velocity, thereby lowering vibration amplitudes to acceptable levels as per balancing standards.
材料
Typically made from high-density materials like leadsteel alloys (e.g.AISI 1018)tungstenor brass. Coatings such as zinc plating or powder coating may be applied for corrosion resistance. Material selection depends on required densityenvironmental conditionsand compatibility with the rotor material.
