Chamfer for Gear Hobbing Tools
When hobbing helical spur gears with large diameters, the hobs cannot always be chosen long enough to cover the entire working area. To prevent excessive wear of the hob teeth in the approach area, the gear hob is produced with a tapered chamfer. For gears with double-helical teeth, two hobs with chamfer may be needed, if the distance between the two tooth rows is relatively small.
Depending on whether hobbing is by the climb or conventional method, the chamfer — generally 5 to 6 x module long and 5° to 10° angle of inclination — is situated on the entering- or leaving end of the cutter. Any more details on quality gear hobbing tools, please visit our new wbesite.
