本专利(美国专利№3958290)是一个能保证间歇运动的行星式传动机构。通过锥齿轮181、182(见图1和图2)将自动冷镦机主轴的回转运动传给中间轴20,而中间轴20借助于具有相同中心距的齿轮副21、31与22、32的传动与行星传动轴30相联系。齿轮21、31为非圆齿轮。齿轮21呈椭圆形,其回转中心与其轮廓的大圆弧的曲率中心相重合。齿轮31的轮廓曲线由两部分组成:一部分为曲率中心与回转中
This patent (U.S. Patent No. 3958290) is a planetary transmission that ensures intermittent motion. The slewing motion of the spindle of the automatic cold heading machine is transmitted to the countershaft 20 via bevel gears 181, 182 (see FIGS. 1 and 2), while the countershaft 20 is rotated by means of gear pairs 21, 31 and 22, 32 having the same center distance The drive is connected to the planetary drive shaft 30. The gears 21, 31 are non-circular gears. The gear 21 is elliptical, with the center of rotation coinciding with the center of curvature of the large arc of its profile. The profile of gear 31 consists of two parts: one part is the center of curvature and the one in rotation
