Description
本申请要求于2018年11月30日提交中国专利局、申请号为CN201811448487.4、申请名称为差动减速机“”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
背景技术：工业应用领域的减速机。利用这种结构达到机械传动的减速与力矩提升。
发明内容：利用相互连接的两个大小齿轮，通过大齿轮咬合固定件里面的环形齿轮，小齿轮咬合运动件里面的环形齿轮，大小两个齿轮的“齿”数不一样而转动圈数一样来达到“差动减速机”的运转。
这种减速机结构简单，制造容易，同时具备精度高使用寿命长的优点，可以广泛应用工业领域，完全可以解决与替代谐波减速机出力小使用寿命短的弱点。比摆线针减速机结构简单安装方便。下面以里面有三个“大小齿”的减速机来说明“差动减速机”的结构和工作原理。
下图为里面有三个“大小齿”的减速机结构图与构件名称。
(具体看说明书中的图1至图6)
主要构件说明如下。
1.电机齿轮(1个)用键固定在电机轴上面。
2.星形齿轮(三个)同时和电机齿轮与外壳内壁下面的环形齿轮咬合，固定在此轮连杆上。
3.“大小齿”(三个)内有轴承，穿在轴承连杆上面。“大小齿”的下面齿轮与外壳内
壁上面环形齿咬合，“大小齿”上面齿轮与“上旋转盖板”的内壁环形齿咬合。
4.齿轮连杆(三根)通过轴承穿在“一体结构件”里面。
5.“上旋转盖板”(一个)通过上下两个轴承扣在外壳里面。内有固定环形齿轮。
6.“外壳”使用时固定不动。内壁固定有上下两个环形齿轮。
7.“一体结构件”上下两个圆盘带轴承，下面扣在“外壳”上，上面扣在“上旋转盖板”上。
(具体看说明书附图中的图1至图6)
根据“差动减速机”的结构，我们假设“大小齿”大齿轮的“齿”数是C2，“大小齿”小齿轮的“齿”数是C4，C5＝C2-C4。当“大小齿”的大齿轮在“外壳”的上环形齿上转动一圈的时候，与此同时小齿轮也转动一圈，但是这个时候“上旋转盖板”只转动C5。这样就达到了减速的目的，同时力矩也得到提升。就是说“差动减速机”是利用相互连接的两个大小齿轮，通过大齿轮咬合一个环形齿轮，小齿轮咬合另外一个环形齿轮，利用大小两个齿轮的“齿”数不一样而转动圈数一样来达到两个环形齿轮的相对较小的运转。
制作“差动减速机”的时候，“大小齿”的齿数与“大小齿”咬合的“环形齿环”的齿数是要遵循公式的。
下面举几个例子。环形大齿轮内圈周长C1表示，环形小齿轮内圈周 长C3表示，“大小齿”的大齿轮周长C2表示，“大小齿”的小齿轮周长C4表示，(周长取齿轮“齿”高度的中间线)。C1-C3＝a。用N表示“差动减速机”里面环形大齿轮的半径是“大小齿”大齿轮半径的倍数，且这四个齿轮的“齿”大小一样那么齿的个数如下。
C1＝2E.C2＝2E/N＝2F C3＝2E-a＝2b C4＝2E/N-a＝2C且是两个“大小齿”减速机还是两个“大小齿”减速机但a＝1 N＝3 C1＝2E C2＝2E/N＝2F C3＝2E-a＝2b C4＝2E/N-a＝2C表格如下
