Roller Pinion System (RPS) is a linear, or rotary, motion control drive. It is similar to conventional rack and
pinion; however, it surpasses traditional drives with a unique pinion
consisting of bearing-supported rollers.
The rollers are designed to engage with a specially engineered tooth profile. The function of the RPS is to convert rotary
motion to linear motion, or vice-versa.
It does this very efficiently, accurately, and with zero-backlash. Thus, it is attractive for many applications,
and can be used on any equipment requiring challenging motion control. In addition to providing unlimited length and
high-accuracy positioning, the RPS facilitates system integration and ensures
optimized performance. The ISO 9409
flange mount pinions can be directly mounted to a flanged gearhead (no shaft
bushing required) and the pinion preloader system includes everything needed to
properly integrate the RPS into a machine design (fasteners, adjustment device,
drawings, etc.). The components are all
pre-selected to work together. This
integrator-focused design simplifies the implementation process by reducing
components and ensuring proper application.
This frees up time for the engineer to focus on more important items. The
company says the RPS is the most
efficient rack and pinion on the market.
It's simple, fundamentally unique, and achieves its zero backlash
inherently with its design. At the core
are the bearing rollers and the engineered tooth profile; they create the
value. Furthermore, to help with
integration, the ISO 9409 pinions mount axially to the gearheads and transmit
their torque via friction. To complete
the package, the preloader system locates with counter-bores. As opposed to locating off the threads, the
counter bores ensure high precision.
