1995年我矿检查提升机时发现减速器低速齿轮点蚀区域超限,齿面磨损严重.因无备件,只好将替换下来的旧齿轮重新装上使用,预计寿命在3年左右,而矿井寿命还有5年,是否再备一台减速器,一时难以确定.后见到介绍“天王星”抗磨节能剂可以延长设备使用寿命的资料,便决定在主提升机减速器上试用. In 1995, when I checked the hoist, I found that the low-speed gear pitting area of ​​the reducer exceeded the limit and the tooth surface was worn seriously, and the worn-out old gear had to be re-installed because of no spare parts and the life expectancy was about 3 years, Another five years, whether to prepare a reducer, for a time difficult to determine.After seeing the introduction of “Uranus” anti-wear energy-saving agent can prolong the service life of the equipment, they decided to try the main hoist reducer.
