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：Two gears are made to mutually compress the component of gear lapping wheel gravity, to
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 larger moment of friction between belt and gear, and the moment of friction is final
To leading to the pressure generating the flank of tooth to gear lapping wheel.Therefore, which can ensure 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, and removal is ground to the flank of tooth of gear lapping wheel
Amount is also uniform.If there are larger 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, under the action of error is rerun a movie, larger circular pitch deviation also can be equal to the tooth ground by all participations
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) mechanism that diameter jumps deviation is corrected：The device gear diameter jumps reduction machine of the reduction mechanism with circular pitch deviation of deviation
It manages similar.When jumping larger tooth participation engagement to gear lapping wheel (A7, B17) diameter, the centre-to-centre spacing of two pairs of gear lapping wheels becomes larger, two pairs of gear lappings
The component of wheel gravity also has increased trend, and causing the normal pressure between the flank of tooth also has 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, larger diameter jumps deviation also can be by
All participations are homogenized the tooth ground and reduce.It, can be into one to grinding back-geared diameter jump error under the action of above two mechanism
Step reduces.
(4) mechanism of spiral deviation is corrected：Installation when the Gear Helix deviation is mainly by Gear Processing or measurement
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 reference plane 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 centre-to-centre spacing of two pairs of gear lapping wheels (A7, B17) is floated, there is small cunning relative to tilting table to gear lapping wheel
Action 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 guide-soft-band high point flatness error be 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, larger spiral deviation can also be reduced by all tooth homogenizing participated in grinding.Under the action of above two mechanism,
It can be further decreased to grinding back-geared spiral deviation.
(5) mechanism of total profile deviation is corrected：Since to gear lapping wheel (A7, the B17) flank of tooth, there are larger total profile deviations, right
Instantaneous angular velocity and angular acceleration during grinding between two gears can change, so as to cause in sliding process between the flank of tooth
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 reduced by all tooth homogenizing participated in grinding.
Under the action of above two mechanism, has the tendency that reduction to grinding back-geared total profile deviation.Due to gradually opening 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 that involute profile deviation measures.
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, only leans on the effect of flank of tooth force of sliding friction that cannot effectively reduce the tooth of gear instead
Wide deviation.

(1) each gear teeth for grinding gear A and B are numbered, and configures the lapping liquid of suitable particle size；
(2) the left flank of tooth first to the left flank of tooth of No. 1 tooth for grinding gear A or the right flank of tooth with No. 1 tooth of the B to gear lapping wheel or the right flank of tooth
Engagement, to gear lapping wheel automatic anti-backlash under gravity；
(3) after motor positive and inverse alternating is to grinding a period of time t, turn off motor；
(4) side connecting rod A or B are pulled out, two pairs of gear lapping wheels is made to be disengaged from, while being actively in driven pulley and loosening shape
State；
(5) any angle to one tooth of gear lapping wheel is rotated, connecting rod A or B are then put down, allows two pairs to grind gear A and B mistake one again
Tooth engagement, while two belt pulleys are in tensioning state；
(6) start motor, continue to grinding according to the operating method of step 3, it is ensured that every time to the time t that grinds with to grinding strategy one
It causes；
(7) step (4)-(6) are repeated, until completing one to grinding cycle T, i.e. a flank of tooth and to all homonymies of gear lapping wheel all
Participate in engagement；
(8) continue to repeat the above steps, it is the integer more than 1 to grinding period 2kT, wherein k to complete even number.
