Position datum level is coplanar；The centre of gyration of two pairs of gear lapping wheels floats, and center is away from the deviation situation automatic fine tune according to meshing gear
It is whole.
(2) to the method for grinding
It is a kind of improve Gear Processing precision to the method for grinding, the rotation of a motor is transported by precision friction wheel (1,9)
It is dynamic to be divided on two opposite belt pulleys (2,11) of direction of rotation, then by V belt translation respectively drive two it is intermeshing right
Gear lapping wheel (A7, B17), and ensure that the transmission ratio of two-way V belt translation is consistent with the transmission ratio to gear lapping wheel, the opposite of transmission ratio is missed
Difference is as follows to operating procedure is ground no more than 2%:
(1) each gear teeth of gear lapping wheel (A7, B17) are numbered, and configures the lapping liquid of suitable particle size；

Loose state；
(5) rotate one tooth of any pair of gear lapping wheel angle, then put down connecting rod (4 or 13), allow two pairs of gear lapping wheels (A7,
B17) wrong a tooth engagement again, while two belt pulleys are in tensioning state；
(6) start motor, continue according to the operating method of step 3 to grinding, it is ensured that every time to the time t ground with to grinding strategy
Unanimously；
(7) step (4)-(6) are repeated, until completing one to cycle T is ground, i.e. a flank of tooth with to all same of gear lapping wheel
Side is involved in engagement；
(8) continue to repeat the above steps, complete even number to period 2kT is ground, wherein k is the natural number greater than 1.
For etc. parameters master gear for, the positions of commutative two pairs of gear lapping wheels (A7, B17) repeats above-mentioned to grinding behaviour
Make, to be homogenized the error generated by the difference of position and transmission ratio.
Master gear is first worked by teeth grinding method to 2~3 grades of economic accuracy, then patent through the invention in practice
The raising Gear Processing precision of proposition to grinding device with to the method for grinding, the machining accuracy of gear is improved into 1 class precision again, will be dropped
The production cost of low 1 class precision master gear, and improve the production efficiency of 1 class precision master gear.
(3) drift correction mechanism
(1) mechanism of production of grinding pressure: mutually compressing two gears the component of gear lapping wheel gravity, thus
Generate the pressure between the flank of tooth.In addition, due to friction pulley (1,9), belt pulley 2,11) and to the radial circle of reference of gear lapping wheel (A7, B17)
The presence of the diameter mismachining tolerance of cylinder, it cannot be guaranteed that the transmission ratio of two-way V belt translation is completely the same.Due to two pairs of gear lapping wheels
(A7, B17) is in meshing state, and two pairs of gear lapping wheel speeds can be forced in the same size.Under the action of this mechanism, one can be made
Side belt pulley generates small slipping phenomenon, and then makes to generate biggish moment of friction between belt and gear, and the moment of friction is final
To the pressure caused generating the flank of tooth to gear lapping wheel.Therefore, which can guarantee to grind under the action of above two mechanism
The generation of pressure can generate grinding removal under the opposite sliding to gear lapping wheel (A7, B17) flank of tooth.
(2) mechanism of circular pitch deviation is corrected: if two pairs of gear lapping wheels (A7, B17) do not have circular pitch deviation, then in the device
In the case that the transmission ratio of two-way V belt translation is constant, the pressure between the flank of tooth is also constant, to gear lapping wheel flank of tooth grinding removal
Amount is also uniform.If there are biggish circular pitch deviations for two pairs of gear lapping wheels, even if the transmission ratio of the device two-way V belt translation is permanent
Fixed, the face pressure to gear lapping wheel is also variation.The big flank of tooth grinding removal amount of pressure also becomes larger, and eventually results in the flank of tooth
Circular pitch deviation reduce.In addition, biggish circular pitch deviation also can be equal to the tooth ground by all participations under the action of error is rerun a movie
Change and reduces.Under the action of above two mechanism, to grinding back-geared circular pitch deviation, including single circular pitch deviation and tooth pitch it is tired
Product total deviation can further decrease.
(3) amendment diameter jumps the mechanism of deviation: the device gear diameter jumps reduction machine of the reduction mechanism with circular pitch deviation of deviation
It manages similar.When jumping biggish tooth to gear lapping wheel (A7, B17) diameter and participating in engagement, the centers of two pairs of gear lapping wheels is away from becoming larger, two pairs of gear lappings
The component of wheel gravity also has the tendency that increase, and the normal pressure between the flank of tooth is caused also to have the tendency that becoming larger.Therefore in the work of the mechanism
Has the tendency that reduction with causing the diameter of the tooth to jump deviation.In addition, under the action of error is rerun a movie, biggish diameter jumps deviation also can be by
It is all to participate in that the tooth ground is homogenized and is reduced.It, can be into one to back-geared diameter jump error is ground under the action of above two mechanism
Step reduces.
(4) mechanism of spiral deviation: installation when the Gear Helix deviation is mainly by Gear Processing or measurement is corrected
Caused by beat.As long as improving the axially mounted benchmark accuracy of gear, the machining accuracy of the Gear Helix will be improved.The invention
The gear mesh grinding device of proposition, workbench working face is from the horizontal by 70 °~80 ° angles, under gravity, to gear lapping wheel
The axially position datum level of (A7, B17) and the working face of tilting table are adjacent to, it is ensured that two pairs of gear lapping wheel shafts are to positioning datum
Precision.Since the center of two pairs of gear lapping wheels (A7, B17) is away from floating, there is small cunning relative to tilting table to gear lapping wheel
Movement is used.Polytetrafluoroethylene (PTFE) guide-soft-band is pasted on the working face of tilting table, and carries out accurate scraping and milled processed,
On be machined with oil groove, and ensure the flatness error of guide-soft-band high point less than 1 μm.During to grinding, to grinding gear tooth width
The area preference of high point contacts, and grinding removal is participated in, to reduce the spiral deviation of gear.In addition, the work rerun a movie in error
Under, biggish spiral deviation also can be participated in reducing the tooth homogenizing ground by all.Under the action of above two mechanism,
It can be further decreased to back-geared spiral deviation is ground.
(5) mechanism of total profile deviation is corrected: since there are biggish total profile deviations to gear lapping wheel (A7, the B17) flank of tooth, right
Instantaneous angular velocity and angular acceleration during grinding between two gears can change, so as to cause between the flank of tooth in sliding process
Generate dynamic force.Under the action of frictional force between dynamic force and the flank of tooth, the opposite high point between the flank of tooth can be removed preferentially.In addition,
Under the action of error is rerun a movie, the total profile deviation of gear lapping wheel (A7, B17) can be participated in reducing the tooth homogenizing ground by all.
Under the action of above two mechanism, has the tendency that reduction to back-geared total profile deviation is ground.Due to gradually opening to being changed after grinding
The direction of line flank of tooth Micro texture makes it along the measurement direction of flank profil involute, this, which is more advantageous to, reduces tooth-face roughness pair
The influence of involute profile deviation measurement.
When two gear-profile deviations are smaller, the dynamic force between gear can also reduce, due between the flank of tooth from tooth root to
The size of tooth top force of sliding friction is variation, cannot only effectively reduce the tooth of gear instead by the effect of flank of tooth force of sliding friction
Wide deviation.
