Description

内凹类圆台形齿轮
技术领域:本发明属于一种机械传动技术，齿轮传动领域，具体涉及一种异形齿轮。
背景技术:目前传动齿轮有多种，直齿轮、斜齿轮、锥齿轮、曲齿、弧齿轮、蜗杆涡轮和非圆齿轮，利用其自身形状属性实现传动目的。
发明内容:为了实现齿轮形状传动属性，将一段圆弧线在圆台实体上，以圆台的实体轴线为中心轴，旋转一周，构建一个内凹类圆台实体，在内凹类圆台实体曲面上建齿，形成齿轮，以实现齿轮外的某一点，到齿轮纵向圆弧齿的各个点，距离相等的目的，将此形状传动属性应用到，一种齿轮传动的无级变速器上。
本发明的技术特点是：在内凹类圆台实体的内凹类圆台实体曲面环上，用曲线将曲面环分成若干个等份的等腰类梯形曲面；等腰类梯形曲面的两个腰，一侧是齿，另一侧是齿道，形成一个等腰类梯形曲面齿域，等腰类梯形曲面齿域上的每条齿平行排列，被腰的另一侧齿道切断，齿道末端截断部形成斜面导域，在斜面导域部分建曲率偏移导域，来进行曲率偏移调整；两个等腰类梯形曲面齿域依次连接时有效组合，使两个等腰类梯形曲面齿域成为一个整体，若干等腰梯形曲面齿域依次首尾排列，在内凹类圆台实体上旋转一周形成内凹类圆台形齿轮。

具体实施方式：
如图1图2图3所示，在等腰类梯形曲面沿一条腰上平行建弧形齿2，弧形齿2被等腰类梯形曲面另一条腰上的齿道4切割，在齿道4的切割面侧，建曲率偏移导域3与平行的弧形齿连接，构成等腰类梯形曲面齿域1，将若干个等腰类梯形曲面齿域1在内凹类圆台实体5上，旋转排列一周，构成内凹类圆台形齿轮。
