Abstract
The invention discloses a method for preparing double cross gear, belonging to mechanical process technology. Said double cross gear is formed with left-and-right involutes helicoids, the cross gear center is the cross point of left gear central line and the right one; if the two cross gear is the same phase, the cross gear center 3 on graduated cylinder gear 1 and cross center 4 on gear 2 are at the same bus wire; and if projected on gear graduated circumference, the two cross gear center 3 and 4 are at the same circumferential position; and if the cross gear center 3 and 4 are at different phase, the cross gear 1 and 2 are at the same phase, then s1 equals to s2, and the center distance of left gear and right gear of two cross gears are equal, 11=12; clamping double cross gear blank on digital control milling machine for preparation.
Description
Affiliated technical field
The present invention relates to a kind of processing method of double helical gear, belong to the Machining Technology field.
Background technology
At present, the processing method of herringbone bear is to process a side gear symbol figure of herringbone bear earlier, is that benchmark marks opposite side gear tool setting line by the tooth of having processed then, by the opposite side gear symbol figure of tool setting line tool setting gear hobbing herringbone bear.Because two herringbone bears on the same axle are to be scribed ss benchmark processing, the double helical tooth center same-phase precision of two herringbone bears that process like this is low, and phase error reaches 1mm.
Summary of the invention
Purpose of the present invention: in order to overcome the low deficiency of double herringbone gear in-phase precision that existing method processes, the invention provides a kind of synchronous processing method in double helical tooth center of new assurance double helical gear, be that left right-hand teeth centre-to-centre spacing equates in the same shaft section by controlling, come the phase difference of indirect controller's word gear centre.This method can be controlled two herringbone bear same-phase precision within 0.03mm, and method is simple, convenient.
Solution of the present invention is: herringbone bear by about revolve and gradually open spiral camber and form, the double helical tooth center is meant left-hand teeth center line and right-hand teeth center line intersection point; If two herringbone bear same-phases then are positioned on the same bus at the cog double helical tooth center 4 of 1 double helical tooth center 3 and gear 2 of gear compound graduation cylinder; Just project on the gear compound graduation circumference, the double helical tooth center 3 and 4 of these two herringbone bears is in identical circumferential position; Otherwise, between the double helical tooth center 3 and 4 of two herringbone bears on the gear compound graduation circumference, form phase angle, i.e. a phase error.
On the expanded view of double helical gear:
The left-hand teeth of herringbone bear 1 and right-hand teeth centre-to-centre spacing l
1For: l
1=2S
1/ tg β;
The left-hand teeth of herringbone bear 2 and right-hand teeth centre-to-centre spacing l
2For: l
2=2S
2/ tg β.
β in the formula---be helical angle.
Because herringbone bear 1 and herringbone bear 2 same-phases are so there is s
1=s
2, then the left-hand teeth of herringbone bear 1, herringbone bear 2 equates with right-hand teeth centre-to-centre spacing, i.e. l
1=l2; The double helical gear axis blank is clamped on the high-precision cnc boring and milling machine, when the processing double helical gear, on herringbone bear on the same shaft section 1 and herringbone bear 2 outside circles, bore four technology pin-and-holes, control technology pin-and-hole symmetry error is in allowing accuracy rating, and assurance herringbone bear 1 equates with the technology pin-and-hole centre-to-centre spacing of herringbone bear 2.Be that benchmark is drawn mill teeth tool setting center line, mill teeth made allowance with the technology pin-and-hole respectively.In the technology pin-and-hole, dial gauge is installed, beat the table look-up pin-and-hole and revolve flank of tooth relative error about adjacent, if error surpasses the scope that allows, by getting a tooth pulled out or going here and there the cutter adjustment, mill teeth again, transverse tooth thickness made allowance, again beat table look-up, revolving flank of tooth relative error about making pin-and-hole adjacent is zero, and the left-hand teeth of assurance herringbone bear 1 and herringbone bear 2 and right-hand teeth center line guarantee promptly that all by technology pin-and-hole center two herringbone bear phase errors are within allowed band.
The invention has the beneficial effects as follows: method is simple, convenient, the double herringbone gear in-phase precision height after the processing.
