这个行星齿轮的减速比是多少？电机8齿，行星轮全部是15齿，大轮带动下一级行星的齿轮是12齿好像，外圈齿轮是42齿这样算对吗：一级(15/8)*(42/15)=5.25二级 (42/15) *(15/12)=3.5三级(15/12) *(42/15)=3.5总和=64

计算多麻烦，你全部装好，转小电机，看看小电机转多少圈主轴才转一圈不就行了
齿轮的传动速度比，只跟初级齿数和最后一级齿数有关，中间的都没有起到变速效果，除非是双层齿轮（多层）。所以这个就不言而喻了。看你这个还有个双层齿轮，把这个双层的比例再乘上去就OK了。没太明白你的描述，但是觉得第一个式子好像不对，单考虑单层的行星齿轮的话，外层的转速就等于外层齿数和电机齿数的比值，跟中间的那三个小齿轮无关，这就是我说的对于单层齿轮只考虑初级末级的道理。这样你再看一下，应该差不多。
这样算也对，其实可以把行星齿轮去掉（只是过渡用），电机=&大圈、小圈=&大圈、小圈=&大圈，1：64的加力减速，空转时还是电机的速度，负载加上时会自动减速。
好东西啊，有金属齿轮吗？
减速比与行星齿数无关。1级：（8+42）/82级：（12+42）/123级：（12+42）/12总的减速比：3级相乘。
楼主的电动螺丝刀质量怎么样，能不能介绍介绍，我正打算淘宝买个
:楼主的电动螺丝刀质量怎么样，能不能介绍介绍，我正打算淘宝买个 ( 18:51) 还凑合吧 其实是3节电池的 我后来加了一节，就是电池不耐用 别的没问题 实惠
:楼主的电动螺丝刀质量怎么样，能不能介绍介绍，我正打算淘宝买个 ( 18:51) 看我以前帖子就行，50块 不要买那种头很多的 都没啥用处
