一种直齿锥齿轮啮合检测工装设计以及啮合分析

Design and meshing analysis of a spur bevel gear meshing detection fixture

设计这个工装的起因源于对于锥齿轮装配间隙的测量。直齿锥齿轮加工件单件检测有许多的检测项目,例如,齿形检测、公法线长度、齿厚、齿高、等等,但是对于另一些描述齿轮啮合的检测项目,没有办法通过单件检测进行测量,必须对锥齿轮进行配对后才能进行检查。所以,为了满足直齿锥齿轮在正式装配前的配对检测需要,我们需要设计一种简单易操作的齿轮啮合的检测工装,再配合一定的检测方法就可以对齿面啮合情况做出判断,例如齿面啮合的侧隙、齿顶间隙、接触斑点等等。

The design of this fixture originated from measuring the assembly clearance of bevel gears.There are many testing items for single piece inspection of straight bevel gear machined parts,such as tooth profile inspection,common normal length,tooth thickness,tooth height,and so on.However,for other detection items that describe gear meshing,it is not possible to measure them through single piece testing,and bevel gears must be paired before inspection can be carried out.So,in order to meet the pairing detection needs of spur bevel gears before formal assembly,we need to design a simple and easy to operate gear meshing detection fixture,and combined with certain detection methods,we can make judgments on the meshing situation of the tooth surface,such as the backlash,tooth tip clearance,contact spots,and so on.
