减速机技术资料：

减速机漏油的原因是什么？
1、减速机内外产生压力差：减速机运转过程中，运动副摩擦发热以及受环境温度的影响，使减速机温度升高，如果没有透气孔或透气孔堵塞，则机内压力逐渐增加，机内温度越高，与外界的压力差越大，润滑油在压差作用下，从缝隙处漏出。
2、减速机结构设计不合理
1）检查孔盖板太薄，上紧螺栓后易产生变形，使结合面不平，从接触缝隙漏油；
2）减速机制造过程中，铸件未进行退火或时效处理，未消除内应力，必然发生变形，产生间隙，导致泄漏；
3）箱体上没有回油槽，润滑油积聚在轴封、端盖、结合面等处，在压差作用下，从间隙处向外漏；
4）轴封结构设计不合理。早期的减速机多采用油沟、毡圈式轴封结构，组装时使毛毡受压缩产生变形，而将结合面缝隙密封起来。如果轴颈与密封件接触不十分理想，由于毛毡的补偿性能极差，密封在短时间内即失效。油沟上虽有回油孔，但极易堵塞，回油作用难以发挥。
3、加油量过多：减速机在运转过程中，油池被搅动得很厉害，润滑油在机内到处飞溅，如果加油量过多，使大量润滑油积聚在轴封、结合面等处，导致泄漏。
4、检修工艺不当：在设备检修时，由于结合面上污物清除不彻底，或密封胶选用不当、密封件方向装反、不及时更换密封件等也会引起漏油。
