Description
Technical field
What the present invention relates to is numerical control machine for lapping spiral bevel gear, particularly be that a plurality of grinding points have the method for same backlash on numerical control machine for lapping spiral bevel gear.
Background technology
When on numerical control machine for lapping spiral bevel gear, grinding the contact zone of a pair of intermeshing spiral bevel gear; Need on the gear lapping machine, confirm the coordinate figure of each grinding point; Ben is backlash values, must be set by experienced gear lapping technology person, and gear lapping technology person whenever provides grinding point tooth depth direction coordinate figure Y1 and grinds a some tooth length direction coordinate figure X1; Will provide a backlash values Z1; When grinding point tooth depth direction coordinate figure Y1 and grinding point tooth length direction coordinate figure X1 variation, backlash values Z1 also will and then change, and debugging bothers very much.
Said backlash values is meant: a pair of spiral bevel gear withdraws from certain distance after doing the engagement of no gap again, make between two gears and produce certain clearance, and the size in this gap is exactly a backlash values.The effect of backlash values is exactly: will spray abrasive sand when grinding a pair of spiral bevel gear, this backlash values is exactly the abundant infiltration for abrasive sand, so that produce better grinding effect, backlash values is identical if each grinds point, and grinding effect can be better.
Fig. 1 is a gear lapping machine drive mechanism floor map in the prior art.
As shown in Figure 1, prior art gear lapping machine drive mechanism comprises: Z1-Z1 axle servomotor 39; Being contained on the Z-Z axle servomotor 39 is Z1-Z1 axle shaft coupling 43 1 ends, and Z1-Z1 axle shaft coupling 43 other ends connect Z1-Z1 axle ball-screw 40; Be fitted in the existing driven pedestal 44 on the existing driven shaft 32; Existing driven pedestal 44 connects existing driven shaft 32 and Z1-Z1 axle ball-screw 40 respectively; Existing driven spiral bevel gear 36 is housed on the existing driven shaft 32.
Existing driven shaft 32 is also done the grinding campaign of X1-X1, Y1-Y1, three directions of Z1-Z1 respectively except that rotating, and said three directions ultimate range movably; Only ± 2.5mm; Driving and having driven shaft 32 now is big roller boxs 37 at the device of X1-X1, Y1-Y1, three directions motions of Z1-Z1, and advancing and retreating by hydraulic cylinder of big roller box 37 drives completion, and advancing of big roller box 37 is that existing driven spiral bevel gear 36 and existing active spiral bevel gear 35 are detected by jettron; Do the engagement of no gap; Therefore, big roller box 37 advances and makes existing driven spiral bevel gear 36 and existing initiatively spiral bevel gear 35 only have a point to do the engagement of no gap, and this point all is set in standard locating distance place usually; Rather than the grinding point, real backlash values of grinding point is set by experienced gear lapping technology person.
The existing driven shaft that X1-X1, Y1-Y1 and Z1-Z1 represent existing driven spiral bevel gear 36 respectively among Fig. 1 along move horizontally, existing driven shaft along vertical move and existing driven shaft mobile vertically.
There is following defective in above-mentioned prior art gear lapping machine:
Because the restriction of structure; Connect leading screw by servomotor and drive mechanical part and can not move three directions of Z1-Z1 vertically along the vertical Y1-Y1 of moving, existing driven shaft and do on a large scale and move along moving horizontally X1-X1, existing driven shaft, especially can not satisfy the amount of movement that moves the Z1-Z1 direction at existing driven shaft vertically, can not satisfy and on the flank of tooth, can both do not have the gap and mesh the grinding point of any amount at existing driven shaft; Each grinds point all will bit by bit go to try to look for backlash values by gear lapping technology person; Thereby can not guarantee that each grinding point all has identical backlash values, so not only efficient is low, complicated in mechanical structure; Adjustment is inconvenient, and has influenced the gear lapping effect.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art; Provide a kind of and drive the structure and the automatic backlash values of measuring of realization that driven wheel of differential moves along the Z-Z direction on a large scale by servomotor; And it is superimposed with theoretical backlash values; Generate new backlash values, realize that each grinding point of numerical control machine for lapping spiral bevel gear has same backlash device and control method.

8). begin the grinding stage:, directly enter into this stage if not generating code does not for the first time then carry out sideshake and detects; Driven spiral bevel gear (136) adds braking torque, and initiatively spiral bevel gear (135) is by speed of setting and direction rotation; Three tooth depth direction coordinate figure X that grind point are given with grinding some tooth length direction coordinate figure Y, and three sideshake coordinate figures that grind point are respectively: R80+R811+R60; R80+R821+R60; R80+R831+R60 is: sideshake difference+theoretical backlash values is a little ground at standard locating distance+standard locating distance place therewith, carries out the grinding of contact zone according to three coordinates that grind point respectively;
9). grind and finish: grind and finish, driven spiral bevel gear (136) loads to be removed; Initiatively spiral bevel gear (135) stops operating; Driven spiral bevel gear (136) returns to original position with active spiral bevel gear (135).
