GEOMETRIC AND GENERATION PARTICILARITIES OF THE TOOTH WITH HYPOCYCLOIDAL CURVED FLANKS
Journal Title: Proceedings in Manufacturing Systems - Year 2012, Vol 7, Issue 1
Abstract
The hypocycloidal flanks of the cylindrical gear teeth have the flank lines defined by lengthened or shortened hypocycloid and the involute profile. The curved and bulged flanks have some advantages, among them being the increased strength in bending and controlled positioning of the contact imprint. The tooth flank generation has on the basis the application of the technological process of milling using a cutting tool with multi-cutters by rolling with mobile line and continuous division. The paper deals with basic aspects regarding kinematics, construction, and running of the multiple cutters milling head for processing teeth with involute profile and hypocycloid at flanks in cylindrical gears. The two curves that define the flank, the involute and hypocycloid, are kinematically and simultaneously generated by rolling. The gears processed by means of the milling head had errors corresponding to the precision steps 8 and 9. The calculation relations and numerical data in the paper contain the basic parameters that define the construction and the adjustment of the tool, generation motions and geometry of the processed teeth.
