Description
Technical field
The present invention relates to gear measurement technology, and in particular to a kind of tooth thickness measuring tool of ring gear.
Background technology
Involute variable tooth thickness gear, abbreviation variable tooth thickness gear.It belongs to a kind of involute gear, perpendicular to each of axis
Tooth form in individual end section is all involute, and the modification coefficient in only each section is different.According to Chinese patent literature
In the tooth thickness measuring tool of a kind of low-angle tooth-thickness-changing gear disclosed in CN102353312A and its background technology of measuring method
Record：For the transverse tooth thickness measurement of involute variable tooth thickness gear, can not be detected with conventional tool and method because being difficult to be accurately positioned
It is very difficult in the transverse tooth thickness of machine accurate measurement variable tooth thickness gear during gear tooth thickness, particularly on-line machining.
For the transverse tooth thickness measurement for becoming transverse tooth thickness ring gear, there is presently no special tooth thickness measurer, however it remains above-mentioned
It is difficult.At present, when carrying out transverse tooth thickness measurement using ring gear tooth thickness measurer, on the one hand, the measuring instrument volume is excessive, individually matches somebody with somebody
Put, generally require to take gear ring to ring gear tooth thickness measurer up, in-convenience in use；On the other hand, for change transverse tooth thickness internal tooth
Circle, it is necessary to measure the location parameter of multiple directions, excessive movement makes the transverse tooth thickness certainty of measurement of change transverse tooth thickness ring gear reduce, operation
Process is again complicated, is not suitable for measuring in on-line machining.
The content of the invention
Problem is measured for the transverse tooth thickness for becoming transverse tooth thickness ring gear, the technical problems to be solved by the invention are just to provide in one kind
The tooth thickness measuring tool of gear ring, it many occasions can quickly, accurate measurement become transverse tooth thickness ring gear transverse tooth thickness, and operation letter
It is single, it is easy to carry.
The technical problems to be solved by the invention are realized by such technical scheme, it include dial gauge dial plate,
End face positioning element, spiral micrometer mechanism and length bar are arranged on the top of spiral micrometer mechanism away from measuring mechanism, dial gauge dial plate,
End face positioning element is located at the middle part of spiral micrometer mechanism, and length bar is installed on the bottom of spiral micrometer mechanism away from measuring mechanism.
Use process of the invention is：The beam support on end face positioning element both sides is placed on an end face of gear ring,
Fixed gauge head of the length bar away from measuring mechanism and mobile gauge head are stretched over most long status in the presence of back-moving spring under nature；
Regulation spiral micrometer mechanism, by gauge head accurate movement of the length bar away from measuring mechanism to the cross section of the flank of tooth to be measured of ring gear,
Distance value H of the measurement point away from end face is obtained, locking screw micrometer mechanism measures the ring gear flank of tooth to be measured with length bar away from measuring mechanism
Cross section on length bar away from, on percentage dial plate read length bar away from value, i.e. M values.
Because the present invention is used for measuring ring gear transverse tooth thickness, using very table and spiral micro-measuring structure, certainty of measurement is high；This
The crucial free degree of invention is few and the rigidity of structure is larger, and certainty of measurement is further improved.The present invention becomes transverse tooth thickness internal tooth in measurement
During circle, it is only necessary to which the base of end face positioning element is leaned against the end face of ring gear, gauge head is adjusted highly, it is possible to directly exist
The length bar on the section is read on dial gauge away from efficient and convenient.
So the solution have the advantages that：Energy is quick, the transverse tooth thickness of accurate measurement change transverse tooth thickness ring gear, and simple to operate,
It is easy to carry.
