INSTALALTION METHOD OF HERRING-BONE GEAR Russian patent published in 2010 - IPC B23P19/00 F16H57/02 

FIELD: machine building.

SUBSTANCE: method includes installation of left and right half-chevron for common shaft. Preliminarily in right half-chevron there are implemented openings for fitter bolts. For common shaft from both sides there are installed flexors, providing guaranteed tightness. Then half-chevrons are installed firmly into butt of membrane, implemented end block with common shaft with guaranteed tightness by external diametre of flexors and receiving of unit of herring-bone gear. On common shaft by means of pins from side of right half-chevron with clearance by bore diametre it is installed processing gear wheel, which with unit is fixed on rests of device, including rests, lever and production toothed wheel, left and right sensing elements. Then unit is turned over up to contact by left sensing element of tooth profile at reference diametre of left half-chevron and it is fixed position of common shaft relative to rests, and by means of processing gear wheel, lever and production toothed wheel it is turned over right half-chevron up to contact by right sensing element the same side of ring gear profile of right half-chevron, the same as of left half-chevron. Then unit is fixed from both sides, taken out from device, it is implemented joint-development piercing of left half-chevron and membrane of common shaft through openings for fitter bolts in right half-chevron, and into received through openings there are installed fitter bolts and they are tightened. Flexors can be implemented in the from of coatings or crease retenting crests.

EFFECT: reduction of wear of assembly gear wheels.
