A QFB(Quasi-Flexible Body) gear is composed of a main body and each tooth body. Each tooth body is connected to the main body by a Spherical joint and Bushing force
Gear geometries are created from the parameters of ISO standards. The tooth profile is represented by multiple arcs. The sprocket tooth geometry data is:
•Created from a predefined data file
•Edited from a predefined data file
•Exported from a predefined data file
•Imported from a predefined data file
