SQ37A型切叶丝机齿轮轴轴承密封和润滑的改进

2012-03-05

　　SQ37A型切叶丝机下排链齿轮轴轴承仅靠防尘垫片保护，在日常清洗排链时轴承内容易进水，导致润滑油劣化进而造成轴承损坏，从而影响排链输送系统的正常运行，影响切丝质量。
　　为此，对SQ37A型切叶丝机齿轮轴轴承的密封和润滑部分进行了改进：即改进了轴承座，使用油封代替原防尘垫片；设计了加油装置；选用新型耐水润滑脂代替原铝基润滑脂。
　　改进后应用效果表明，增强了齿轮轴轴承的密封防水能力，减少了进水对轴承的损害；实现了对轴承的周期性润滑，提高了润滑脂的可靠性。轴承的使用寿命由原来的6个月提高到18个月,，降低了轴承的更换频次，减小了维修工作量，降低了备件成本。
