保丽龙雕刻机主轴噪音大怎么办？
来源：http://www.jmycnc.com 时间：2021-12-06
下面就一起来看看开料机主轴噪音大原因及解决方法，希望对大家有所帮助
Let's take a look at the causes and solutions of high noise of the main shaft of the cutting machine, hoping to help you
主轴在工作时有噪音，有时没有，声音大小还不定，这个主要是数控开料机或木工雕刻机的零件外表的波纹度导致的，需要改进轴承滚道外表加工质量，改进轴与轴承座的精度装置办法。那么，在现实操作中，面对主轴发出的一些噪音，主要有以下四种：
When the spindle is working, there is noise, sometimes there is no noise, and the sound size is uncertain. This is mainly caused by the waviness of the part surface of the NC cutting machine or woodworking engraving machine. It is necessary to improve the processing quality of the bearing raceway surface and the accuracy of the shaft and bearing seat. Then, in real operation, there are mainly four kinds of noise emitted by the spindle:
一、淅沥淅沥的声音：由保持器与滚动体振动、冲撞产生，不管润滑脂种类如何都可能产生，承受力矩、负荷或径向游隙大的时候更容易产生
1、 Intermittent sound: it is generated by the vibration and collision between the retainer and the rolling element. It may occur regardless of the type of grease. It is more likely to occur when the bearing torque, load or radial clearance is large
解决方法：保持器精度、选用游隙小的轴承或对轴承施加预负荷、降低力矩负荷，减少安装误差、选用好的油脂
Solution: keep the accuracy of the retainer, select the bearing with small clearance or apply preload to the bearing, reduce the torque load, reduce the installation error, and select good grease
二、杂质音：由轴承或好的清洁度引起，发出一种不规则的异常音，声音时有时无，时大时小，在电机上发生频繁
2、 Impurity sound: it is caused by the bearing or good cleanliness. It emits an irregular abnormal sound, sometimes no, sometimes large and sometimes small, which occurs frequently on the motor
解决方法：选用好的油脂、注脂前的清洁度、加强轴承的密封性能、安装环境的清洁度
Solution: select good grease, the cleanliness before grease injection, strengthen the sealing performance of the bearing and the cleanliness of the installation environment
三、嗡嗡的声音：马达无负荷运转发出类似蜂鸣一样的声音，且马达发生轴向异常振动，开或关机时有嗡嗡声
3、 Buzzing sound: when the motor runs without load, it makes a sound similar to buzzing, and the motor has abnormal axial vibration. There is buzzing sound when it is turned on or off
解决方法：多出现在润滑状态不好，以及在冬天且两端用球轴承的马达，主要是轴调心性能不好时，轴向振动影响下产生的一种不稳定的振动
Solution: most motors with poor lubrication and ball bearings at both ends in winter are unstable vibration under the influence of axial vibration when the shaft centering performance is poor
四、哒哒的声音：声音频率随轴承转速而变化，零件表面波纹度是引起噪音的主要原因
4、 Clatter sound: the sound frequency changes with the bearing speed, and the surface waviness of parts is the main cause of noise
解决方法：改良轴承滚道表面加工质量，降低波纹度幅值、减少碰伤、修正游隙预紧力和配合，检查自由端轴承的运转，改良轴与轴承座的精度安装方法
Solution: improve the surface processing quality of bearing raceway, reduce the amplitude of waviness, reduce bumps, correct the preload and fit of clearance, check the operation of free end bearing, and improve the precision installation method of shaft and bearing seat
数控开料机加工时，主轴是重要组成部分，作用大，很容易出问题，有时会产生很大的噪音。如果在工作中产生嗡嗡的蜂鸣声，那就是主轴出现了问题，不能完成在负荷状态下的工作，建议是更换主轴或进行维修。
In NC cutting machine processing, the spindle is an important part and plays a great role. It is easy to have problems and sometimes produce a lot of noise. If there is a buzzing sound during work, it means that the spindle has a problem and cannot complete the work under load. It is recommended to replace the spindle or carry out maintenance.
