To damping bearing, measurement plate, which is arranged above bearing holder (housing, cover) and with supporting plate front, to be close to, and damping bearing upper end is fixed with measurement plate
The lower face of connection, measurement plate is horizontal, and the supporting plate front is additionally provided with perpendicular to the positive rack of supporting plate, and rack, which is located at, to be surveyed
Below template.
Tooth height is that gear teeth the sum of is risen with height of teeth root, can also pass through measurement radius of addendum and root radius calculates two
Person's difference obtains.In the utility model device, gear is coaxially socketed on rack, traverse measurement plate drops to and gear
Upper top surface contact, measurement plate rises and declines in damping bearing effect rotate gear after a week, keeps stablizing, measure at this time
The lower face of plate and the outside circle of gear are tangent.Gear is pushed into rack bottom again, gear is made to be close to supporting plate front, makes gear
Tooth root it is face-up, the distance of root face to measurement plate lower face is tooth height at this time.
Preferably, one end that the measurement plate is close to supporting plate is equipped with longitudinal slot, standard quarter is plugged in slot
Spend plate.
Master scale plate can be plugged in longitudinal slot, master scale plate, which is drawn, normal line and upper and lower two error lines, marks
Directrix is reference addendum, and the range between up-down error line is to allow error range.It is filled before measurement according to gear under test model
If compatible master scale plate, the location of root circle the top vertex can determine that whether gear teeth height is marked by visual observation
It is quasi-.
Preferably, the rack is made of polished rod portion and threaded shank, supporting plate is equipped with screw hole compatible with threaded shank,
Polished rod portion is fixedly and coaxially connected with threaded shank and threaded shank one end connects tabula rasa portion, the other end extends back across the screw hole of supporting plate
And it is equipped in end and holds portion.Gear is installed in polished rod portion, and can be by being socketed rubber ring again in polished rod portion to enhance to gear
Fixed effect, by turn the portion of holding can drive threaded shank and polished rod portion rotate and to supporting plate it is mobile, more steadily.
Preferably, the polished rod portion and the junction of threaded shank are additionally provided with a snap-gauge.
Snap-gauge can be avoided the phenomenon that accidentally producing supporting plate in use, rack is caused to fall off threaded shank hair
It is raw.
The beneficial effects of the utility model are:
1) the utility model can directly measure whether it complies with standard to the measurement that tooth height is standardized；
2) single unit system structure novel, operation difficulty is low, precision is high.
