Nexen Group's RPS Direct Mount Pinions and Preloader Systems

The 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.
