HBDLAS2555,此变速器由传动比i=25变到传动比证=40,是由输入与输岀轴同时反向旋转自动变速,又水泥管挤压机生产工艺允许,所以可用(2)校核热功率查表A6-表A8得:f1=1.15,1=0.94,∫=1.15,计算热功率P2为P2t=P2ff2f3=51×1.15×0.94×1.15≈63.5kW查表A4知:Pa=35.12kW>P2=63.4kW,满足热平衡要求。3)核算公称转矩T2是否满足要求查表8,40型公称转矩为:T=23520Nm,T2=39200Nm;实际负载转矩为12176Nm=9550P295525≈19482Nm因为T2’=19482Nm8000满足给定要求。(5)结论:选用HBDL40--55型变速器完全满足水泥管挤压机配套使用要求。JB6135-1992附录B变速器载荷分类(参考件)表BI载荷类别主机名称化工机械类搅拌机(液体)离心机(轻型)起重、传送运输机械类均匀载荷)吊杆起落齿轮装置、简式面粉传送机食品、塑料机械类灌注机、包裝机、塑料(薄膜、棒料)挤岀机、压光机建筑、起重机械类搅拌机(固体)、压平机、卷扬机(转臂式起重、机动铰车转向)、齿轮传动裝置、水泥管挤压机传送运输机械类(中等冲击载荷)平板式〔链条式、连杄式、螺旋式)、传送机、升降机矿山、冶金纺织机械类强磁选机、轧钢机滚道、织布机、洗涤机橡胶、造纸、石、瓷、机械类H密炼机、开炼机、压延杋、球磨机、搅浆机、挤压粉碎机、振动式运输机〔强冲击载荷)起重、传送运输、建筑机械类行走齿轮传动装置、筒式(带式)传送机、倾斜式卷扬机、活塞式压缩机附加说明本标准由机械电子工业部西安重型机械研究所提出并归口。本标准由湖南省机械硏究所负责起草。本标准主要起草人周干绪、龙爱华、李涛。閂中华人民共和国机械行业标准混合少齿差星轮变速器B/T6135-199机械科学研究院出版发行机械科学研究院印刷(北京首体南路2号邮编10004)开本88×123058印张2%字数680001992年10月第一版1992年10月第一次印刷印数0.001-500定价6.00元编号0795机械工业标准服务网:htp:/ww.JB.accn
