某矿1台20世纪80年代的JKM3.25×4(Ⅱ)型提升机,配用的是ZHD2R-140型减速器,该减速器高速齿轮轴的轴承是巴氏合金浇铸的滑动轴承,在生产运行中存在许多问题,严重影响了设备的安全运行。1滑动轴承在使用中的主要问题(1)为了提产达标,提升机满负荷连续运转,高速轴轴承发热严重,有时不得不停产降温,严重影响安全生产。(2)轴承使用寿命短,更换频繁,平均每副轴瓦使用3个月左右,最短时不到2个月就得更换。滑动轴承检修更换工艺复杂,技术要求高,更换轴瓦时的
A mine in the 1980s JKM3.25 × 4 (Ⅱ) type hoist with the ZHD2R-140 reducer, the reducer high-speed gear shaft bearings are Babbitt-cast bearings, in the There are many problems in the production and operation, seriously affecting the safe operation of the equipment. A sliding bearing in use the main problems (1) in order to raise production standards, hoist full load continuous operation, high-speed shaft bearing a serious fever, and sometimes had to stop cooling, seriously affecting the safety in production. (2) Bearing life is short, frequent replacement, the average use of each bearing about 3 months, the shortest time less than 2 months have to be replaced. Sliding bearing repair complex process replacement, technical requirements, the replacement of bushings
