Abstract
A method of machining gears or other toothed articles wherein the workpiece feed rate and/or the tool shifting is varied so as to produce an irregular surface pattern on tooth surfaces with a resulting reduction in mesh noise. The method is particularly applicable to grinding spur and/or helical gears with a grinding worm.
Claims15
A method of grinding a toothed workpiece having at least one tooth surface wherein a threaded grinding wheel is moved relative to the tooth surface along a feed path extending in a direction along the tooth surface of the workpiece, said method comprising:
- bringing the tooth surface and the threaded grinding wheel into contact with one another and moving the threaded grinding wheel relative to the workpiece in the feed path direction along the tooth surface at a varying feed rate whereby the spacing of grinding micro scratches will be irregular along the tooth surface,
- wherein the varying feed rate comprises:
- defining a constant reference feed rate and defining a predetermined number of segments along the feed path, and
- moving the threaded grinding wheel through the number of tooth segments while providing a feed rate in each segment that varies from the reference feed rate.
