With the inventive method, tooth root-tip clearance is optimized and the contact ratio is maximized while avoiding root-tip interference between mating gear members. | 01-31-2013 |
20120328383 | CONTINUOUS METHOD FOR MANUFACTURING FACE GEARS - A continuous method of manufacturing a face gear utilizing a tool, representing a plane which can be oriented to a face gear workpiece under an angle equal to the pressure angle of the mating pinion member of the gear set (e.g. the face gear set), and, which can be rotated around a virtual pinion axis to generate a tooth flank on the workpiece. The tool is a face cutter which performs a continuous indexing motion with equal hand of rotation of cutter and workpiece (e.g. face gear) thereby describing a hypocycloid path of motion and an indexing ratio of two cutter rotations during one workpiece gear rotation which will produce straight lines along the face width of the face gear. | 12-27-2012 |
