| Summary: | On the basis of the analysis on the circular-arc-tooth-trace cylindrical gear， the geometrical parameters of involute elliptic-arc-tooth-trace cylindrical gear are expounded. It can be concluded that the tooth profiles remain the same involute on any vertical axis section， its tooth thickness is equal to the slot width on the different vertical axis section of the gear teeth， and pressure angle at the reference circle is equal， the expanded tooth trace on reference cylinder is a symmetrical elliptical arc. The equations of tooth surface， transverse tooth profile and contact curve are derived. Meantime， the tilting rotary cutter processing method is proposed. The models of the gear special cutters are established in VERICUT. The elliptic-arc-tooth-trace cylindrical gear machined by the tilting rotary cutter processing method is carried out by VERICUT machining simulation. The contact curve characteristics of the gear pair are analyzed by using the gear models obtained from the simulation. The results show that the elliptic-arc-tooth-trace cylindrical gear pair can achieve full tooth width curve contact， which verifies the feasibility of the machining method. It provides the basis for the machining and application of the involute elliptic-arc-tooth-trace cylindrical gear. |
