For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of double-helical tooth centring error-tested method, after the complete left-hand teeth of finish-milling, the processing line of right-hand teeth drawn by milling machine and mills out right-hand teeth, by inspected number ball inspection left-hand teeth and right-hand teeth corresponding points straight line variation in the vertical direction on milling machine, its operating procedure is as follows:
1) cylindrical handle of inspected number ball is placed on the left-handed end face of gear, pommel and the left-hand teeth end profile of tooth of inspected number ball are tangent, carriage arbor establishes dial gauge, the external cylindrical surface of cylindrical handle is beaten with dial gauge, require that dial gauge is beaten in the maximum bus position in the cylinder left side, cylindrical handle garden or the right, write down jitter values;
2) above-mentioned inspected number ball is taken off be put into corresponding dextrorotation increment, cylindrical handle and the gear dextrorotation end face of inspected number ball are fitted, pommel and the right-hand teeth end profile of tooth of inspected number ball are tangent, then beat the maximum bus place in the left side or the face of cylinder, the right of cylindrical handle with dial gauge, write down jitter values;
3) according to step 1) and step 2) middle dial gauge jitter values, left-hand teeth and right-hand teeth straight line variation value in the vertical direction can be known, using the error of centralization of this deviate as left-hand teeth and right-hand teeth, determine the adjustment direction of feed next time, finish-milling right-hand teeth, by controlling within the scope of 0 ~ 0.01mm by the dial gauge jitter values of left-handed increment and dextrorotation increment two positions, can ensure that the double helical tooth error of centralization is less than or equal to 0.01mm.
A kind of inspected number ball, comprise cylindrical handle, pommel, neck bar, cylindrical handle is coaxially connected successively with neck bar and pommel, and described pommel diameter is 1.65 times of modules, cylindrical handle diameter 5 ~ 15mm larger than pommel diameter.
Compared with prior art, the invention has the beneficial effects as follows: inspected number spherical structure is simple, easily manufactured, use is flexible, for double-helical tooth centring error-tested, easy to operate, precision easily controls, and facts have proved the high accuracy centering requirement that can meet processing herringbone bear completely, effect is satisfactory.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
See Fig. 1, Fig. 2, it is a kind of double-helical tooth centring error-tested of the present invention view, on gear-hobbing machine after the complete gear left-hand teeth 1 of finish-milling, the processing line of right-hand teeth 2 drawn by gear-hobbing machine and mills out right-hand teeth 2, then on gear-hobbing machine, the deviation of linearity in the vertical direction of left-hand teeth 1 end and right-hand teeth 2 end is checked by inspected number ball 3, when linearity deviation is zero, think that double-helical tooth centring error is zero, the method is convenient to the centering that work in-process adjusts double helical tooth at any time, the inspected number ball 3 used in the method, comprise cylindrical handle 4, pommel 6, neck bar 5, cylindrical handle 4 is coaxially connected successively with neck bar 5 and pommel 6, pommel 6 diameter is 1.65 times of modules, cylindrical handle diameter 5 ~ 15mm larger than pommel diameter, this method of inspection operating procedure is as follows:
1) neck bar 5 side plane of the cylindrical handle 4 of inspected number ball is placed on left-hand teeth 1 side gear end face, the pommel 6 of inspected number ball is tangent with left-hand teeth 1 end profile of tooth, carriage arbor 8 is established dial gauge 7, the external cylindrical surface of cylindrical handle 4 is beaten with dial gauge, require that dial gauge 7 dozens is in the maximum bus position in the cylinder left side, cylindrical handle 4 garden or the right, the position of the relative carriage arbor 8 of dial gauge 7 is motionless, writes down jitter values;
2) above-mentioned inspected number ball 3 is taken off be put into right-hand teeth 2 end, neck bar 5 side plane and gear right-hand teeth 2 end face of the cylindrical handle 4 of inspected number ball 3 are fitted, the pommel 6 of inspected number ball is tangent with right-hand teeth 2 end profile of tooth, use the maximum bus place in the external cylindrical surface left side of dial gauge 7 dozens of cylindrical handles 4 or the right again, write down jitter values;
3) basis and step 1) and step 2) in twice jitter values of dial gauge 7, right-hand teeth 2 end and left-hand teeth 1 end linearity deviate in the vertical direction can be drawn, using this deviate as the error of centralization with right-hand teeth 2 of left-hand teeth 1, and then finish-milling right-hand teeth 2 revises deviate, as long as control within the scope of 0 ~ 0.01mm by the dial gauge jitter values of left-hand teeth 1 end and right-hand teeth 2 end two positions, can ensure that the double helical tooth error of centralization is less than or equal to 0.01mm.In processing, left-right rotary transverse tooth thickness can be processed by nominal size, and because transverse tooth thickness is all negative common difference, the processing one more feed of gear completes.Then detect with inspected number ball 3, determine the adjustment direction of next step finish-milling right-hand teeth 2 according to testing result.
