Assignee:

Dentsply International Inc. - York PA

International Classification:

A61C 1/12

US Classification:

433114, 433133

Abstract:

A dental handpiece includes a body having a first portion and a second portion, the first and second portions disposed at an ergonomic angle to each other. A drive gear extends from the second portion toward the first portion. The drive gear has a first axis of rotation and rotatably drives at least one driven gear having a second axis of rotation. The at least one driven gear is operatively connected to a bur disposed in the first portion to rotatably drive the bur about a third axis of rotation. The drive gear and the at least one driven gear do not include a taper gear or a face gear.

Abstract:

A burnishing gear or burnishing die has a plurality of spiral gashes formed within each one of the burnishing gear teeth at a predetermined angle with respect to a transverse plane so as to define shearing edges along side involute portions of the burnishing gear teeth. The shearing edges enable enhanced finishing or burnishing operations to be performed upon workpiece gears in order to effectively remove positive imperfections, irregularities, nicks, or the like from the workpiece gear teeth so as to finish the workpiece gear in accordance with desired tolerances. The burnishing gear may be incorporated within burnishing gear systems utilizing burnishing gears characterized by different operating pressure angles as well as within burnishing gear systems that have mechanisms for reciprocating the workpiece gear during a gear burnishing operation.
