Method has several, and distance over bar M values are to react a thick measurement index of gear compound graduation knuckle-tooth, because measurement accuracy is higher, in reality
It is widely used in the production of border.
Gear tooth thickness can be controlled by modes such as measuring tooth thickness and distance over bar, and specific metering system is as follows：Due to reference circle
Circular tooth thickness is not easy to measurement, so the transverse tooth thickness deviation generally said is evaluated with reference circle chordal tooth thickness.Measure reference circle string tooth
The conventional gear tooth vernier calliper measurement of thickness, its advantage is easy to carry, easy to use.Because chordal tooth thickness measurement is using outside circle as base
Standard, the accuracy and concentricity of tip cylinder will directly affect its measurement result, thus direct measurement transverse tooth thickness be difficult to reach compared with
High measurement accuracy.The transverse tooth thickness of gear controlled using the distance over bar of amount post method prototype gear, it is to avoid position error, relatively measured
Transverse tooth thickness sensitivity is high, measurable high class gear, and therefore, most common method is prototype gear across rod in gear measurement
Away from.
At present, " amount post method " measurement distance over bar is generally adopted by, this method can reach accurate measurement, still
Also there are some limitations：Present parts are all batch machinings, when will consume substantial amounts of using length bar, outside micrometer measurement
Between, because each part will high-volume rod, then miking；Every is wanted circumference to measure respectively at 3 points, and so get off every need
The time of measuring for wanting 2-3 minutes, is not suitable for the demand of mass production checkout procedure, can not meet enterprise to high efficiency
It is required that, meanwhile, this measuring method is affected by factors, can also cause measurement data inaccurate：As length bar abrasion, thousand points
Chi abrasion, placement location etc..
