43、是一种动力传达机构，利用齿轮的速度转换器，将电机（马达）的回转数减速到所要的回转数，并得到较大转矩的机构。在目前用于传递动力与运动的机构中，减速机的应用范围相当广泛，几乎在各式机械的传动系统中都可以见到它的踪迹，从交通工具的船舶、汽车、机车，建筑用的重型机具，机械工业所用的加工机具及自动化生产设备，到日常生活中常见的家电，钟表等等.其应用从大动力的传输工作，到小负荷，精确的角度传输都可以见到减速机的应用，且在工业应用上，减速机具有减速及增加转矩功能。因此广泛应用在速度与扭矩的转换设备。减速机的作用主要有： 1） 降速同时提高输出扭矩，扭矩输出比例按电机输出乘减速比，但要注意不能超出减速机额定扭

44、矩。 2）减速同时降低了负载的惯量，惯量的减少为减速比的平方。大家可以看一下一般电机都有一个惯量数值。蜗轮蜗杆减速机分类：主要型号：WP系列蜗轮蜗杆减速机、WH系列蜗轮蜗杆减速机和CW系列蜗轮蜗杆减速机等。 1. WP系列蜗轮蜗杆减速机包括WPA/WPS/WPW/WPE/WPZ/WPD 2. WH系列蜗轮蜗杆减速机包括WHT/WHX/WHS/WHC 3. CW系列蜗轮蜗杆减速机包括CWU/CWS/CWO 4. RV系列蜗轮蜗杆减速机包括RV/NMRV/NRV蜗轮蜗杆减速机的常见问题及分析：1 减速机发热和漏油。2 蜗轮磨损。3 传动小斜齿轮磨损。4 蜗杆轴承损坏。1 减速机发热和漏油 为了提高

45、效率，蜗轮减速机一般均采用有色金属做蜗轮，蜗杆则采用较硬的钢材。由于是滑动摩擦传动，运行中会产生较多的热量，使减速机各零件和密封之间热膨胀产生差异，从而在各配合面形成间隙，润滑油液由于温度的升高变稀，易造成泄漏。造成这种情况的原因主要有四点，一是材质的搭配不合理；二是啮合摩擦面表面的质量差；三是润滑油添加量的选择不正确；四是装配质量和使用环境差。 2 蜗轮磨损 蜗轮一般采用锡青铜，配对的蜗杆材料用45钢淬硬至HRC4555，或40Cr淬硬HRC5055后经蜗杆磨床磨削至粗糙度Ra0.8m。减速机正常运行时磨损很慢，某些减速机可以使用10年以上。如果磨损速度较快，就要考虑选型是否正确，是否超负荷

46、运行，以及蜗轮蜗杆的材质、装配质量或使用环境等原因。 3 传动小斜齿轮磨损 一般发生在立式安装的减速机上，主要与润滑油的添加量和油品种有关。立式安装时，很容易造成润滑油量不足，减速机停止运转时，电机和减速机间传动齿轮油流失，齿轮得不到应有的润滑保护。减速机启动时，齿轮由于得不到有效润滑导致机械磨损甚至损坏。 4 蜗杆轴承损坏 发生故障时，即使减速箱密封良好，还是经常发现减速机内的齿轮油被乳化，轴承生锈、腐蚀、损坏。这是因为减速机在运行一段时间后，齿轮油温度升高又冷却后产生的凝结水与水混合。当然，也与轴承质量及装配工艺密切相关。 解决方法：1保证装配质量。可购买或自制一些专用工具，拆卸和安装减速

47、机部件时，尽量避免用锤子等其他工具敲击；更换齿轮、蜗轮蜗杆时，尽量选用原厂配件和成对更换；装配输出轴时，要注意公差配合；要使用防粘剂或红丹油保护空心轴，防止磨损生锈或配合面积垢，维修时难拆卸。 2润滑油和添加剂的选用。蜗齿减速机一般选用220#齿轮油，对重负荷、启动频繁、使用环境较差的减速机，可选用一些润滑油添加剂，使减速机在停止运转时齿轮油依然附着在齿轮表面，形成保护膜，防止重负荷、低速、高转矩和启动时金属间的直接接触。添加剂中含有密封圈调节剂和抗漏剂，使密封圈保持柔软和弹性，有效减少润滑油漏。 3减速机安装位置的选择。位置允许的情况下，尽量不采用立式安装。立式安装时，润滑油的添加量要比水平

48、安装多很多，易造成减速机发热和漏油。 4建立润滑维护制度。可根据润滑工作“五定”原则对减速机进行维护，做到每一台减速机都有责任人定期检查，发现升温明显，超过40或油温超过80，油的质量下降或油中发现较多的铜粉以及产生不正常的噪声等现象时，要立即停止使用，及时检修，排除故障，更换润滑油。加油时，要注意油量，保证减速机得到正确的润滑。蜗轮蜗杆减速机国家标准：TP型平面包络环面蜗轮减速机（JB/T9051-1999） CW系列圆弧圆柱蜗杆减速器（JB/T7935-1999） ZC1型双级蜗杆及齿轮-蜗杆减速器（JB/T7008-1993） SCW轴装式圆弧圆柱蜗杆减速机（JB/T6387-1992）
