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.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
