Linear Rail System

Haydon Kerk Motion Solutions, a division of AMETEK Precision Motion Control (Waterbury, CT), has introduced the BGS04 Linear Rail System designed for high-moment loads. The roll, pitch, and yaw moment load capability allows the system to maintain accuracy and repeatability in applications requiring significant cantilevered loading. The system features a Haydon™ linear actuator driving a Kerk® 303 stainless steel precision lead screw. The screw is coated with Black Ice® TFE coating, providing a permanent wear-resistant dry lubrication. The lead screw drives an anti-backlash nut embedded in a machined aluminum carriage mounted to a stainless steel ball rail. The linear rail is available with either the Size 11 (28mm) double stack or Size 17 (42mm) single stack hybrid linear actuator. Maximum roll, pitch, and yaw moments are 5.72 lb-ft, 4.88 lb-ft, and 5.68 lb-ft, respectively.

Factors to Consider When Selecting and Specifying LVDT Linear Position Sensors

Fitting the right type of linear position sensor to an application requires at least a working knowledge of the attributes of this electromechanical device. Starting with the basics, the LVDT (linear variable differential transformer) is a common type of linear position sensor widely used in electromechanical systems today. It consists of two basic elements: a stationary coil assembly and a movable core or armature. While most LVDTs are fundamentally AC-in/AC-out devices, some have electronics built-in to make them DC-in/DC-out devices. This gives rise to the terms “AC-LVDTs” and “DC-LVDTs”.

Connectors Enable Precise Movement of Lunar Robotic Tool Changer

NASA’s Langley Research Center in Hampton, VA hired Honeybee Robotics Spacecraft Mechanisms Corp. to develop a totally mechanical tool changer for the end of what Langley’s Lunar Surface Manipulation System (LSMS) team describes as a robot that could unload landers. Then, after the landers were unloaded, it could, in addition to doing base assembly, mate with tools to take science experiments. This robot could be likened to a crane, but with more dexterity.

Automation Control Platform

GE Intelligent Platforms (Charlottesville, VA) has announced the PACSystems® control and computing platform designed for the industrial Internet. It incorporates COM Express architecture with multi-core CPUs. The RXi platform offers high-speed interfaces, with multiple gigabit Ethernet and USB 3.0 ports. These features are coupled with GE’s PACSystems control engine. The controllers feature built-in redundant PROFINET interfaces, and can run HMI, Historian, and analytics applications at the machine, even in harsh environments.

Harmonic Gearhead

Nexen Group (Vadnais Heights, MN) has announced a harmonic gearhead that directly replaces much larger, high-ratio planetary gearheads utilizing the latest harmonic strain wave gearing technology. In addition to its compact size, the gearhead features high torque, true zero backlash, and positional accuracy. A gearing-forward design overlaps components and allows the gearing to be integrated into the same plane as the bearing, resulting in a short and rigid gearhead. This narrow, rigid design is combined with a large, rugged, crossed-roller output bearing, designed to handle all combinations of radial, axial, and overturning moment loads in a single, compact envelope. The gearhead can fit virtually any machine, and can operate in less than half the space of conventional planetary gearheads.

Helical Gearbox

GAM Gear (Mt. Prospect, IL) has introduced the SPH series inline planetary gearbox featuring helical gearing. It is designed for dynamic and cyclic motion control applications, and can be optimized for high-speed and continuous-duty applications. The gears are cut at an angle to help reduce axial forces associated with helical gearing, and then are ground for reduced noise levels and improved smoothness. The gear teeth are wider, allowing for larger permissible torques relative to the frame size, and heavy-duty taper roller bearings enable large loading capabilities.
