滚珠丝杠副表面质量对噪声性能影响的试验研究

Experimental Study on Influence of Surface Quality of Ball Screw Pair on Noise Performance

针对滚珠丝杠副噪声测量试验给出了测量系统的组成和原理,在此基础上针对不同表面粗糙度和不同转速下的KD4032端塞式滚珠丝杠副进行了噪声测量试验。试验结果分析表明,滚道表面波纹度的激励频率计算值与噪声测量所得的主频基本一致且波纹度为噪声的主要来源,可以通过提高表面加工质量达到降低噪声、改善国产滚珠丝杠副高速性能的目的。

The composition and principle of the measurement system are given for the ball screw pair noise measurement test.On this basis,noise measurement experiments of KD4032 ball screw pair with different surface roughness and different speed are carried out.The analysis results shows that the calculated value of the excitation frequency of the raceway surface waviness is basically the same as the main frequency obtained from the noise measurement and the waviness is the main source of noise.By improving the surface processing quality,we can reduce noise and improve the high-speed performance of domestic ball screw pairs.
