SEW減速机噪音问题该如何快速找到原因?

噪音是现在很多机器的通病,出现的比较的普遍,关键是要看我们怎麽去解决。SEW减速机使用时间长了或者出现了什麽故障,都会或多或少的出现壹些噪音问题,这个时候我们就该逐个去排查分析塬因到底出在了哪里。下面就由SEW减速机厂家来带着大家壹下壹些常见的问题点,以便用户能够及时的找出问题并处理。

Noise is now a common problem of many machines, the emergence of a more common, the key is to see how we solve. SEW reducer used for a long time or what fault will more or less appear some noise problems, this time we should have one by one to the investigation and analysis of the plateau exactly where. The following by the Shanghai SEW reducer manufacturers to bring you one of the common problems, so that the user can find out the problem and deal with.

1.SEW减速机内部齿轮误差影响:齿轮制造过程齿形误差、基节偏差、齿向误差和齿圈径向跳动误差是导致行星减速机传动噪声的主要误差。也是控制行星减速机传动效率的壹个问题点。现以齿形误差与齿向误差做简单说明。

1.SEW error: internal gear reducer gear manufacturing process of tooth profile and pitch deviation, tooth error and tooth ring radial runout error is the main error planetary gear transmission noise. It is also a problem to control the transmission efficiency of planetary reducer. The present paper gives a brief description of the tooth profile error and tooth direction error.

齿形误差小、齿面粗糙度小的齿轮,在相同试验条件下,其噪声比普通齿轮要小10dB。齿距误差小的齿轮,在相同试验条件下,其噪声级比普通齿轮要小6~12dB。但如果有齿距误差存在,负载对齿轮噪声的影响将会减少。

Under the same experimental conditions, the noise of the gear with small tooth profile and small tooth surface roughness is smaller than that of the conventional gear 10dB. Under the same experimental conditions, the noise level of the gear with small tooth pitch error is smaller than that of the conventional gear 6~12dB. However, if there is a pitch error, the effect of load on the gear noise will be reduced.

齿向误差将导致传动功率不是全齿宽传递,接触区转向齿的这端面或那个端面,因局部受力增大轮齿挠曲,导致噪声级提高。但在高负载时,齿变形可以部分弥补齿向误差。

The error of the tooth direction will cause the transmission power is not transmitted by the whole tooth width, and the end face or the end face of the contact area of the steering gear is increased, and the noise level is improved due to the increase of the local force. However, when the load is high, the tooth deformation can partly compensate the error of the tooth profile.

2. 装配同心度和动平衡:装配不同心将导致轴系运转的不平衡,且由于齿论嚙合半边松半边紧,共同导致噪声加剧。高精度齿轮传动装配时的不平衡将严重影响传动系统精度。

2 concentricity and dynamic balance of assembly: the assembly will not lead to the imbalance of the operation of the shaft, and because the tooth meshing half of the loose side of the tight, resulting in increased noise. The unbalance of high precision gear assembly will seriously affect the precision of the transmission system.

3.SEW减速机内部齿轮硬度:随着齿轮硬齿面技术的发展,其承载能力大、体积小、重量轻、传动精度高等特点使其应用领域日趋广泛。但为获得硬齿面采用的渗碳淬硬使齿轮产生变形,导致齿轮传动噪声增大,寿命缩短。为减少噪声,需对齿面进行精加工。目前除采用传统的磨齿方法外,又发展出壹种硬齿面刮削方法,通过修正齿顶和齿根,或把主被动轮的齿形都调小,来减少齿轮嚙入与嚙出冲击,从而减少齿轮传动噪音。

3.SEW gear reducer gear hardness: with the development of hard gear surface technology, its high bearing capacity, small volume, light weight, high precision transmission characteristics make it more widely applications. But to get hardened by carburizing and quenching hard gear deformation, resulting in gear transmission noise, shorten the life of. In order to reduce the noise, the tooth surface should be machined. At present, in addition to the traditional grinding method, and develop a hard skiving method by modifying the tooth top and root, or the tooth wheel are active and passive transfer of small, to reduce the gear meshing in and out of shock, thereby reducing gear transmission noise.

4.SEW减速机系统指标检定:在装配前零部件的加工精度及对零部件的选配方法(完全互换,分组选配,单件选配等),将会影响到系统装配后的精度等级,其噪声等级也在影响範围之内,因此,装配后对系统各项指标进行检定(或标定),对控制系统噪声是很关键的。

4.SEW reducer system index test: in the machining accuracy of parts before assembly and the selection method of spare parts (complete interchangeability, matching, matching, single etc.) will affect the precision grade to the system after the assembly, the noise levels also affect the scope, therefore, after the assembly for the calibration of the indicators system (or calibration) that is key to the noise control system.

通过以上的项目分析,大家是不是心里都该有个底了?下次碰到SEW减速机噪音问题,应该处理起来就会得心应手了。

Through the above analysis of the project, we are not in the heart of the end of the next encounter SEW reducer noise problems, it should be handled with ease.
