管式捻股机噪声源主要在筒体和齿轮箱体，其噪声控制筒体重点在筒壁厚度的设计、制造精度和使用时的维修质量；齿轮箱体内齿轮重点在制造精度和啮合质量，保证传动平稳；轴承重点在选择合适的轴承类型和精度，调整好间隙和预紧力。其余噪声源在三角皮带、链条传动等方面，提高其传动质量，才能有效地控制噪声源。 The main source of noise of tubular twisting machine is in cylinder and gear box. The focus of its noise control cylinder is on the design of tube wall thickness, manufacturing precision and quality of service during use. The gear in gear box focuses on manufacturing precision and meshing quality, To ensure a smooth transmission; bearing the focus in the selection of suitable bearing type and accuracy, adjust the clearance and preload. The remaining noise source in the V-belt, chain drive, etc., to improve its transmission quality, in order to effectively control the noise source.
