大修车床时,如何保证横向传动齿轮副尺寸链 a(见图示)是常见的问题。机修手册中,除介绍用“增加补偿环”和“移置溜板箱”的方法外,还介绍了用“变位齿轮”的方法,但怎样求得变位量,手册中无介绍。下面我介绍一种用测量车床横向传动齿轮副的中心距来求变位量的方法。 When overhauling the lathe, it is a common problem to ensure that the side chain a (see illustration) of the transverse drive gear. Machine repair manual, in addition to introducing the “increase compensation loop” and “displacement of the skateboard” approach, but also introduced the use of “variable gear” method, but how to find the displacement, the manual is not introduced. Now I introduce a method of measuring the amount of displacement by measuring the center distance of the lathe horizontal gear pair.
