2 蜗轮磨损。蜗轮一般采用锡青铜，配对的蜗杆材料一般用45钢淬硬至HR5一55,还常用40C:淬硬HRC50一55，经蜗杆磨床磨削至粗糙度RaO. 8 fcm,行星减速机正常运行时，蜗杆就象一把淬硬的“锉刀”，不停地锉削蜗轮，使蜗轮产生磨损。一般来说，这种磨损很慢，象某厂有些行星减速机可以使用10年以上。如果磨损速度较快，就要考虑行星减速机的选型是否正确，是否有超负荷运行，蜗轮蜗杆的材质，装配质量或使用环境等原因。

变频器来说，都有一个正常的工作电压范围，当电压超过这个范围时很可能损坏变频器，常见的过电压有两类。输入交流电源过压这种情况是指输入电压超过正常范围，一般发生在节假日负载较轻，电压升高或降低而线路出现故障，此时断开电源，检查、处理。发电类过电压这种情况出现的概率较高，主要是电机的同步转速比实际转速还高，使电动机处于发电状态，而变频器又没有安装制动单元，有两起情况可以引起这一故障。当变频器拖动大惯性负载时，其减速时间设的比较小，在减速过程中，变频器输出的速度比较快，而负载靠本身阻力减速比较慢，使负载拖动电动机的转速比变频器输出的频率所对应的转速还要高，电动机处于发电状态，而变频器没有能量回馈单元，因而变频器支流直流回路电压升高，超出保护值，出现故障，而纸机中经常发生在干燥部分，处理这种故障可以增加再生制动单元，或者修改变频器参数，把变频器减速时间设的长一些。

按其结构，铸铁平板分为筋板式和箱体式，岩石平板分为凸缘式和无凸缘式按其用途分为检验平板、划线平板和压砂平板按其准确度级别分为、、3级平板，其中2级以上为检验平板，3级为划线平板。这样的划分进一步保证了高精度平板的工艺性能和内在质量。培养平板（cultureplat是被用于获得微生物纯培养的最常用的固体培养基形式，它是冷却凝固后的固体培养基在无菌培养皿中形成的培养基固体平面，常被简称为平板（plat。
