双点冲床偏心套偏心距超差的补救

Remedy of Eccentricity Errors of an Eccentric Bushing in Double-point Press

一对偏心套偏心距超差的补救,除采用选配法、投料法、修配法外,还可采用"借镗"中心孔的方法。"借镗"中心孔将导致偏心套上的齿圈变成"偏心齿轮",影响齿轮啮合时的重合度和齿侧间隙,但通过计算可知,只要"借镗"量控制在一定范围内,可满足齿轮的正确啮合条件。

In order to repair the eccentricity errors of an eccentric bushing, a new ＂re-processing center hole of the eccentric bushing＇remedy has been put forward in the text besides the traditional remedies including Matching, Reproduction and Repair.Though this remedy will cause the gear of eccentric bushing change into eccentric gear which affects the contact ＆ overlap ratio and teeth side clearance. By computation results, conditions of gears meshing can be met when the value of rcmediation is controlled within a certain range.
