产品描述
产品用途及特点:
LMX立式磨机专用系列减速器是吸收、消化国外MAAG、 Flender、住友等公司的技术,结合本公司多年积累的设计、制造硬齿面齿轮的经验推出的系列产品。最大功率达5000KW,可满足10000t/d新型干法水泥粉末设备要求。
 
技术特点:
1、广泛应用于建材、电力、冶金等行业。
2、结构:采用伞齿轮行星齿轮传动,减速机与磨机融为一体,输出法兰直接与磨盘相接来传递扭矩,同时承受来自
磨辊的压力。立磨压力通过轴向止推轴承及圆筒形对称的减速器箱体直接传递到基础上,安全可靠。
3、齿轮、轴、箱体为均衡设计。减速器箱体设计为圆筒形且作坚固加强,其加工精度极高,刚度分布均匀。其主要件进行了有限元分析。
4、伞齿轮副采用克林根贝尔格齿制,所有齿轮均采用优质高级合金钢制造并经渗碳淬火磨齿加工,太阳轮和行星轮采用修形技术和齿根强化喷丸处理。
5、全部齿轮在坯料阶段和精加工后均进行探伤检查。对箱体和行星架的主要焊缝均进行超声波探伤。运用先进的焊接设备和焊接工艺,确保箱体和行星架的高强度及高刚性
6、所有滚动轴承寿命均大于8万小时。
7、采用动静压、静压润滑系统,运转安全可靠。
8、采用非接触机械密封,不渗油,无须更换。
9、本系列减速机具有体积小、重量轻、效率高、噪声低、振动小、运行平稳、寿命长等特点。其主要技术指标均达到同类产品先进水平。
