减速机技术资料：

行星减速机是由蜗轮、蜗杆、铸钢机壳、平面压力轴承，锥度轴承以及油封组成，广泛的应用在工业制作，首要用于塔式起重机的反转组织。其行星减速机蜗杆也称为曲纹面圆柱蜗杆其中齿面通常为圆弧形凹面。那么行星减速机常见的缺陷有哪些呢?
1、行星减速机运用进程呈现噪音：因为疾速行星减速机多头蜗杆的分头不均匀，慢速呈现噪音的缘由是轴承的质量疑问。
2、行星减速机呈现温升过高以及卡死：减速机正常作业状态下最高温度不得跨过45摄氏度，如呈现高温应立即连续机器查看，通常呈现这种疑问的原由于选用此吨位的减速机偏小超负荷表象，或蜗杆以及蜗轮端盖协作压入过紧呈现的高温状况，输入转速也不清扫在外蜗轮减速机为黄油光滑，蜗杆轴最高转速不得跨过1000min/s，如输入转速过高也会呈现高位以及卡死等状况，高温的处置办法是下降输入转速、查看压盖的嵌入协作是不是过紧以及是不是行星减速机缺油表象。
3、减速机在正常的运用进程中出现振动： 行星减速机在运用进程中附加载荷后呈现的哆嗦缘由均为丝杠螺距不均匀、蜗杆分头不均匀、平面压力轴承以及锥度轴承质量不合格、丝杠的上下护套协作过紧，以及设备的不一样心疑问。
4、行星减速机运动障碍的剖析： 对行星减速机运动障碍性缺陷进行剖析的常用办法是，首先要查清缺陷发作的首要特征，尤其是缺陷翻开进程中发作的各种痕迹，再由痕迹剖析损害零件的受力联络，找出发作反常力的缘由，或许由缺陷特征联络有关部件的方案特征进行剖析，就可以抵达弄懂缺陷本源的意图。
5、由断口微观特征剖析零件的开裂缘由： 断口是指零件开裂后构成的天然外表。断口的微观剖析是指直接由人的视觉，或许仰仗放大镜查询零件断口的特征，依据这些特征，定性地区别零件发作开裂缺陷的缘由，从而为清扫缺陷作业的修补方案供应重要依据。
