Claims
- 1. A rack for burnishing toothed gears comprising: a unitary body of an elongated shape having leading and trailing ends and a toothed face extending therebetween; said unitary body having a flat mounting surface facing in the opposite direction as the toothed face; said unitary body also having a pair of parallel side walls that face in opposite directions away from each other and extend in a perpendicular relationship from the mounting surface to the toothed face; said toothed face having at least a leading section and a trailing section respectively located adjacent the leading and trailing ends of the unitary body; and one of said sections of the toothed face being slightly inclined with respect to the other section and the mounting surface in a lateral direction along the elongated length of the unitary body so as to provide each burnished gear tooth with accentuated axial crowns intermediate the axial ends of the tooth.
- 2. A rack as in claim 1 wherein the toothed face of the unitary body further includes an intermediate section located between the leading and trailing sections; and said intermediate section of the toothed face being slightly inclined in a lateral direction along the elongated length of the unitary body with an opposite inclination as said one section from said other section.
- 3. A rack as in claim 2 wherein the leading section of the toothed face extends parallel to the mounting surface; and the intermediate and trailing sections of the toothed face each being slightly inclined with respect to the leading section and the mounting surface in a lateral direction along the elongated length of the body with opposite inclinations as each other.
- 4. A rack as in claim 3 wherein the intermediate and trailing sections of the toothed face are each inclined with respect to the leading section thereof the same angular extent.
- 5. A rack for burnishing toothed gears comprising: a unitary body of an elongated shape including leading and trailing ends and a toothed face extending therebetween; said unitary body including a flat mounting surface that faces in an opposite direction as the toothed face and also including a pair of side walls that face in opposite directions away from each other and extend in a perpendicular relationship from the mounting surface to the toothed face in a parallel relationship to each other; said toothed face of the unitary body including a leading section extending parallel to the mounting surface at the leading end of the rack; the toothed face also including an intermediate section that is slightly inclined with respect to the leading section and the mounting surface in a lateral direction along the elongated length of the body at a location between the leading and trailing ends thereof; and the toothed face also including a trailing section that is slightly inclined with respect to the leading section and the mounting surface in a lateral direction along the elongated length of the body at the trailing end thereof and with an opposite inclination of the same angular extent as the intermediate section from the leading section.
