Gear construction method and digital apparatus

摘要

The present invention relates to a gear construction method, including the steps of: i) setting gear parameters and an XYZ coordinate system; ii) according to the gear parameters, creating a first curve (1) associated with an involute of a tooth profile of a target tooth in an XZ plane, and creating a second curve (2) associated with the involute of the tooth profile of the target tooth in a YZ plane; iii) combining the first curve (1) with the second curve (2) to form a third curve (3) and projecting the third curve (3) onto an XY plane to obtain the involute (4) of the target tooth; and iv) constructing a tooth profile of the target tooth and form a solid model of the entire gear by using the involute (4). The present invention also relates to a digital apparatus associated with the above gear construction method.
