反转技术在DTM350/600型磨煤机上的应用
摘要
分析钢球磨煤机长期使用后
大齿轮单边磨损严重
齿轮啮合恶化
传动部振动增大的问题
对其实施大齿轮反转技术改进
使大齿轮和小齿轮非工作面变为工作面
齿轮啮合情况趋好
乙侧小齿轮受力方向改变
传动平稳。反转技术的应用较大地延长了大齿轮使用寿命。
Abstract
The problem existing on ball mills after long-term operation
i.e.severe abrasion on single side of the large gear wheel
making the engagement between gear wheels to be worsened
and the vibration of driving parts to be increased
has been analysed.After implementation of retrofitting the large gear wheel by adopting the reverse rotation technology
the non-working surface on large and small gear wheels has turned into working surface
the engagement between gear wheels being perfected
stressed direction of small gear wheel at B side has been changed
the transmission being stable.The application of reverse rotation technology has greatly prolonged the service life of said large gear wheel.
