Title:
HELICAL GEAR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2009233722
Kind Code:
A
Abstract:
To provide a method for manufacturing a helical gear by which the helical gear can precisely be manufactured.
In the method for manufacturing the gear, including a gear-cutting process for forming a roughly-processed gear by applying the gear-cutting to an outer circumferential surface of a blank and a tooth surface forming process for forming the tooth surface by pressing a form-rolling die to the roughly-processed tooth surface of the roughly-processed gear, the length (processed part length T) of the portion receiving a plastic deformation to the roughly-processed tooth surface with the form-rolling die is shorter than the length of the tooth width W on the roughly-processed tooth surface.
