纯滚动零压力角传动系统
技术领域
改变速比新方法通过轴向叠加的槽轮、 滚轴、 槽圏改变速比。
纯滚动零压力角传动系统涉及一种动力传递的新方法。 通过轴向叠加的槽 轮、 滚轴、 槽圏, 传递动力。 用这种新的传动系统, 可避免传统的齿轮传动过程 中出现的因压力角造成的径向分力及因重合度小造成的机构体积大的缺点。
背景技术
目前公知的动力传递方法: 可通过齿轮、 摆线轮、 蜗轮副 ... ...等机构实现。 纯滚动零压力角传动系统是对本人申请的专利申请号为 201010129285. 0;专利名 称为滚柱传动装置及专利申请号为 200910222392. 5;专利名称为滚动联轴器两项 发明的合并与改进。
发明内容
传统的动力传递方法可通过齿轮、 摆线轮、 蜗轮副……等机构实现。 所有这 些方法均不能实现动力传递过程中的, 纯滚动、 零压力角、 高重合度传动; 尤其 是需通过一级传动得到大传动比时, 高速旋转的输入轴需承受很大径向分力; 是 传统的动力传递方法无法解决的。 纯滚动零压力角传动系统通过解决以下问题可 实现一级变速得到大传动比, 可做得到动力传递过程中所有运动件的纯滚动、 高 重合度、 零压力角传递动力。
技术难题:
1.解决运动过程中的干涉。
2.实现多滚轴啮合。 3.实现滚轴在槽圏槽、 槽轮槽中运动时其运动方式为纯滚动。
4.实现小压力角, 甚至可做得到零压力角。 大幅度减小径向分力。
5.实现大扭矩传递。
6.完成对从槽轮到输出轴运动的纯滚动转换。
纯滚动零压力角传动系统通过以下六个措施解决以上技术问题。
1.通过在轴向错位安装的槽轮、 槽圈及弹性圏解决运动过程中的干涉。 滚轴 在槽轮槽、 槽圏槽中运动, 弹性圈施力于滚轴使槽轮槽中的滚轴有向半径增大方 向运动的趋势。 在输入轴偏心部及弹性圏作用下, 槽轮同时完成对槽圏中心公转 及槽轮的自转。 弹性圏使滚轴进入槽轮槽, 槽圈槽的共同作用下完成啮合, 而封 闭的槽轮槽又能使槽圈槽中即将脱离啮合的滚轴拉出槽圏。
2.只要在槽轮槽中心线与槽圏槽中心线交点处的滚轴均可正常啮合,适当地 选择相关参数可实现多滚轴啮合。 其重合度远大于齿轮啮合。
3.在外扭矩的作用下滚轴被夹持在槽轮槽壁与槽圈槽壁间,槽轮的运动使滚 轴作纯滚动。
4.因槽轮槽、 槽圈槽, 中心线与其槽壁的夹角为压力角。 当槽轮的槽壁平面 通过槽轮轴向中心线时压力角为零。 槽轮、 滚轴、 槽圈所构成的系统在槽轮压力 角为零时, 其扭矩传递过程中的径向分力为零。
5.金属抗剪切能力较抗拉抗压能力差, 沿轴向错位布置数个槽轮、 槽圈, 可 增加对滚轴的剪切截面。 多滚轴啮合加之对滚轴的多剪切截面所产生的效果是使 用槽轮、 滚轴、 槽圈运动副, 传递扭矩远比使用齿轮副所传递的扭矩大。
6.槽轮的运动为绕槽圏中心的平动与转动的合成, 驱动盘、 输出轴端面加工 有可安装带滚动体的保持架的孔, 带滚动体的保持架, 夹持孔盘两端凸起的驱动 块完成槽轮到输出轴运动的转换。
以上措施可实现一种全新的纯滚动、无径向分力、 高重合度、结构简单紧凑, 体积小、 高效率的传动系统。
因纯滚动零压力角传动系统输入轴无径向分力、体积小可直接与电机联接制 作大扭矩低速电机。
