HWB125包络减速机的蜗杆轴向截面齿廓为直线，故称其为直廓环面蜗杆（亦称球面蜗杆），与其他各种蜗杆减速器相同，为空间交错轴传动，承载能力和传动效率较高。HW系列包络减速机适用于重载、大功率、大转矩传动，如冶金、矿山、起重、运输、石油、化工、建筑等机械设备的减速传动。包括HWT、HWWT、HWB、HWWB型四种形式。HWB包络减速机工作条件：输入、输出轴交错角为90℃；蜗杆转速不超过1500r/min;蜗杆中间平面分度圆滑动速度不超过16m/s；蜗杆轴可正、反向运转；工作环境温度为-40℃~40℃。当工作环境温度低于0℃时，启动前润滑油加热到0℃以上，或采用低凝固点的润滑油；高于40℃时，采取冷却措施。HWB包络减速机标记示例HWB包络减速机标记HWB型减速机外形、安装尺寸及装配型式JB/T7936－1999HWB包络减速机结构图型号aB1B2B3C1C2Hd1l1b1t1L1HWB100100250220501009010028js660831220HWB1251252802606011510512535k6801038260HWB1601603803107015513016045k61101448.5340HWB2002004503608018515018055m61101659380HWB2502505404309022518020065m61401869460HWB28028064050011027021022575m61402079.5530HWB31531570053012028022525080m61702285590HWB35535575056013030024528085m61702290610HWB40040084062014031526031595m617025100660HWB450450930700150355300355100m621028106740HW***05001020760170400320400110m621028116790型号d2l2b2t2L2L3L4H1hd3油量/L重量/kgHWB10050k6821453.52202201203732516370HWB12560m682186424026014244530204132HWB16075m61052079.531032017756035248170HWB20090m61302595350380192655402413280HWB250110m616528116430440230800452821475HWB280120m616532127470530255910503527725HWB315130m6200321375005552609635535351030HWB355140m62003614853059030010826035481590HWB400150m62003615856065531012307042602140HWB450170m62404017964070536013757542852510HW***0180m624045190670775390151080421103370)
