ABSTRACT:
A ring gear burnishing machine is disclosed that has a pair of burnishing stations in which ring gear workpieces are burnished in an overlapping cycle that minimizes burnishing time. Each burnishing station consists of a support table which is coupled to an air cylinder spring and is vertically displaceable so that a burnishing gear is placed on the support table when it is in its lowered position, and burnishing takes place when the support table is in its raised position. Burnishing is accomplished by a pair of burnishing gears at each station. One of the burnishing gears of each pair is driven and the other burnishing gear of the pair is an idler gear. A gear engagement mechanism that includes a pivotable support holder and a pair of rollers which engage the periphery of the ring gear is designed so that the rollers, which do not distort the ring gear, push it into mesh first with one of the rotating burnishing gears, and then with the other burnishing gear of the pair. The rollers force the ring gear to move so the center axis of the ring gear, which is initially displaced from the center of the support table, is positioned to coincide with the center point of the support table. The ring gears are fed onto the support tables in an alternating manner by an oscillating shuttle arm which forces the ring gears onto the support tables. The operation of the support tables and the gear engagement mechanism are controlled by cam surfaces on a rotating cam which controls cam followers that are positioned on opposite sides of said cam and are maintained apart against the force of a third air cylinder spring.
