Abstract: In this paper, the engagement
of the rack and pinion steering gear with variable ratio is
emphatically discussed by means of conjugate theory. The method
and procedure are established to calculate the teeth flanks of
the rack. Meanwhile, a significant conclusion is drawn: the rack
and pinion remain in linear mesh regardless of the installation
angle and the ratio, and the teeth flanks of the rack are
developable. Furthermore, the machining mechanism is studied,
with some valuable results obtained.
Key words:
