Process Design Input Analysis
Part Functional Assignment Description
A shaft is a part of a machine designed to transmit torque and perceive active forces from the parts and supports located on it.
The main purpose of the shaft is to transmit torque. Actuating surface of shaft is working stages with key slot on which gear wheel is based by means of key joint.
Defining Primary and Secondary Design Bases
Description of Basic and Auxiliary Design Bases
1. The main design bases - the common axis of the cylindrical surfaces ∅30????, 6 a double guide hidden base, deprives the part of 4 degrees of freedom; the end of the shaft berth is a support base, deprives the part of 1 degree of freedom .
2. Auxiliary design bases - the axis of symmetry of key slots is a support hidden base, deprives 1 degree of freedom.
