The adjustment snap ring selected rule
Technical field
The utility model relates to a kind of measuring gage, and especially a kind of adjustment snap ring is selected rule.
Background technology
Because being assembled to, gear need carry out axial restraint to gear after axle is gone up; All adopt snap ring that it is carried out axial restraint in the general design, owing to adding up of dimension chain, the thickness of snap ring has three or four kinds at least usually; Reach kind more than ten at most; If the snap ring of selecting has approached, axial motion when then can cause gear operation causes vibrations, noise etc.; If the snap ring of selecting is thick, then can cause the snap ring card insecure, snap ring comes off during gear operation, the gear string is moving etc., causes serious accident.
Summary of the invention
Select the deficiency of rule in order to overcome existing snap ring, a kind of adjustment snap ring that provides of the utility model is selected rule.
The utility model solves the technical scheme that its technical matters adopted: a kind of adjustment snap ring is selected rule, it is characterized in that:
It is made up of adjustment snap ring selected rule left side branch, adjustment snap ring selected rule right side branch and straight hand lever;
The adjustment snap ring selected rule middle part is arranged one straight hand lever;
The adjustment snap ring selected rule both sides are selected rule left side branch and adjustment snap ring for the adjustment snap ring and selected rule right side branch;
The adjustment snap ring select middle and lower part that rule left side branch and adjustment snap ring selected rule right side branch respectively correspondence have several sections to measure stages.
The invention has the beneficial effects as follows: processing is simple, easy to operate, efficient is high, and snap ring thickness is selected accurately can mistake not select snap ring.
Below in conjunction with accompanying drawing and specific embodiment the present invention is done explanation further.
