Description
Technical Field
The utility model relates to the technical field of gear machining.
Background
The gear is a mechanical element on the rim, which is continuously meshed by gear teeth to transmit motion and power, and for a gear transmission structure, the meshing precision between the gears directly influences the transmission efficiency of the transmission structure because the power transmission is realized through mutual meshing, and the precision of the gears needs to be detected after the gears are processed. For detection of gear accuracy, the value of M, namely the gear span, can be measured. The M value is an indirect parameter representing tooth thickness, two small round bars are clamped in opposite tooth grooves, the distance between the two small round bars is measured, namely a span bar distance M value, the small round bars are called measuring bars, and the diameter of the measuring bars is a standard value (similar to a standard gauge block). The value of the span M is a measurement index reflecting the tooth thickness of the gear reference circle. The measuring precision is higher, and the method is widely applied to production practice. The traditional measurement of the span bar distance M value does not have a related clamp, does not have a gear fixing device, and is low in measurement accuracy and efficiency through manual measurement.
