举一反三
- 如图所示,已知:n1=1450r/min;Z1=18;Z2=87;Z3=28;Z4=20;Z5=84。求:i15=?
- 图示手摇提升装置,z1=20,z2=50,z′2=15,z3=15,z′3=1,z4=40,z′4=18,z5=54,则传动比i15= 。[img=455x476]1803be1b2a961fb.png[/img]
- 如图所示轮系,已知z1=15,z2=25,z2’=15,z3=30,z3’=15,z4=30,z4’=2(右旋),z5=60,z5’=20,m=4mm。若n1=500r/min,求齿轮5的速度n5。
- 如图所示,已知z1=24, z2=28, z3=36, z4=20, z5=80, z6=24, z7=32, z8=24, z9=36,i19=。https://p.ananas.chaoxing.com/star3/origin/0fe106f4796f18e469f5eefa94509939.jpg
