the small gear wear and tear caused by vibration
General design principle is that the
cement ball mill is weak and big gear ring, at the same time, small gear tooth number is less than the big gear ring, so they often appeared phenomenon is small a little gear surface corrosion phenomenon than the big gear ring and steps. So mill downtime is need on a regular basis to the pinion and the big ring gear tooth surface inspection, attention to the dynamic of tooth surface wear.
Personally think pinion and the
cement ball mill in four aspects: a, normal wear and tear, that is occurring in the process of normal use of wear and tear. Second, the improper lubrication, unreasonable mainly used lubricating oil, is vital for a device to select the correct lubricating oil. Three, lubricating oil, for a device to choose the suitable lubricating oil, still need to observe the change of the lubricating oil, when using six months or a year, according to the brand and work environment) has been a professional company to assay of oily, look to whether can meet the production requirement now. Fourth, the existence of stolen goods, this is open gear, such as sealing oil tools, such as not clean do bad or very easy to cause the goods inside, bring serious damage of pinion and big teeth.
When there is serious wear and tear or small gear pitting phenomenon, can lead to a backlash, a loud crash will be issued at the same time, the direct cause of tooth surface wear was accelerated. Usually treatment method is to use the pinion to turn over. In the process of being turned to ensure that the backlash in the design requirements, personally think that the importance of the backlash is greater than the tip clearance.
