Patent number: 10265777Abstract: A spacer for gear hobbing machine, a gear hobbing machine incorporating same, and an associated method are provided. The spacer includes a bore. One or more adjustment members are carried by the spacer and adjustable into and out of the bore. Adjustment of the adjustment members allows for varying the position of the spacer when mounted on an arbor of the gear hobbing machine.Type: GrantFiled: July 31, 2017Date of Patent: April 23, 2019Assignee: Bourn & Koch, Inc.Inventor: Loyd L. Koch

Patent number: 9067269Abstract: A gear shaping machine is provided. The gear shaping machine includes a pair of horizontally reciprocating gear shaping heads mounted to a column. Each gear shaping head includes a spindle assembly including an integral rotary drive for indexing the spindle. The spindle assembly is carried by a spindle slide. The spindle slide also carries a plurality of bearing blocks to allow for sliding movement of the gear shaping head relative to rails mounted on the column. A linear drive arrangement is operably coupled between each gear shaping head and the column. The linear guide arrangement allows for controlled linear translation of each gear shaping head independently of one another. Each gear shaping head also includes a back-off mechanism for independently moving the spindle assembly toward the workpiece during a cutting stroke and away from the workpiece during a return stroke of each gear shaping head.Type: GrantFiled: October 13, 2011Date of Patent: June 30, 2015Assignee: Bourn & Koch, Inc.Inventors: Loyd L. Koch, Hans Grass, Wayne Densmore

Patent number: 8985917Abstract: A cutting machine for gear shaping or the like is provided. The cutting machine includes a gear shaping head. The gear shaping head has a ram that is guided by and reciprocates along a linear guide mounted between a saddle of the gear shaping head and the ram. At least one linear motor reciprocates the ram along a stroke axis relative to the saddle. The ram also carries a rotary drive and a spindle that reciprocate in unison with the ram. The rotary drive directly drives the spindle to journal the spindle through incremental angular positions during gear shaping.Type: GrantFiled: April 21, 2010Date of Patent: March 24, 2015Assignee: Bourn & Koch, Inc.Inventors: Loyd L. Koch, Hans Grass, Wayne Densmore

Patent number: 7097399Abstract: A cutting machine includes linear electrical actuation for controlling linear reciprocating movement of a spindle and cutting tool. The cutting machine is suited for gear shaping cutting operations and the like. Linear electrical actuation may be used to control position of a hydraulic valve within the spindle, which controls hydraulic actuation and linear movement of the spindle. Linear electrical actuation may also be used to pivot the spindle to relieve the cutting and/or during the cutting stroke for gear crowning operations. A rotary actuator is also disclosed as incorporated into the pivoting saddle of such a cutting machine.Type: GrantFiled: August 20, 2004Date of Patent: August 29, 2006Assignee: Bourn & Koch, Inc.Inventors: Bob Winfough, Loyd L.
