Linear Guide Systems

LM76 (E. Longmeadow, MA) offers the Speed Guides™, two series of high-speed, compact linear guide systems. The Speed Demon OSG type and Speed Demon SG type linear guide systems are ideal for used in X, Y, or Z axes, and are designed for speeds up to 10 m/sec., accelerations to 50 m/sec.2, and loads up to 5600 N. The OSG systems are available in five rail and block sizes. Rails feature pre-drilled mounting holes, dual RC60 steel shafting in lengths up to 4 meters, and can be cut to size. Each OSG block features 4 dual-contact roller bearings with two bearings on eccentric mounts. Running straightness is ±0.02 mm regardless of system length. Integral felt wipers, high angular dual contact bearings, and corrosion resistant materials permit installation in a broad range of adverse environments. Shafting options include RC60, 440C, and chrome plating.

Cable Assemblies

W.L. Gore & Associates (Elkton, MD) has introduced Gore™ Eye-Opener® DensiShield cable assemblies to transmit high-speed differential signals while reducing size and weight. A short cable exit and lightweight cable allow a tighter fit between the chassis panel and door. The high-speed cable incorporates ultra-low-dielectric materials.

Motion Control ICs

Performance Motion Devices (Lincoln, MA) released the Magellan™ family of motion control ICs. They provide smooth stop, abrupt stop, and system disable, and are available for DC brush, brushless DC, microstepping, and step motors. A hardware trace buffer can store four performance-related values chosen from over 28 recordable variables. Selectable variables include position servo lag, motor output, servo integral, and commutation angle, among others. Collected data can be analyzed to determine increases in machine wear or vibration, or whether other user-defined or performance-related conditions have occurred. Magellan’s automatic machine monitoring system handles conditions such as motion error, positive and negative limit switches, position breakpoints, and commutation monitoring. Other features include a programmable PID filter with velocity and acceleration feed forward, 32-bit position error, dual biquad filters, and multi-chip synchronization.

Rail System

From LEE Controls (Piscataway, NJ) and designed for automated production lines, CNC machines, power transmission, and other linear motion applications, the SBC Profile Rail System incorporates linear guide rails and blocks and is available in two ranges for high load capacity and two ranges for ultra-high-load applications. Rail lengths up to 4000 mm are available. A seal protects the ball bearings within the guide block and lubrication can be provided through a grease fitting. Available accessories include side grease fitting for obstructed applications, bellows to prevent dust and debris from impairing travel, and scrapers to remove contaminants from high-temperature machining operations.

Reciprocating Platform

Amacoil (Aston, PA) offers a reciprocating linear motion platform driven by a rolling ring drive that reciprocates automatically without requiring motor reversal. Designed for a PCB measurement/cleaning process, the assembly may also be used for scanning barcodes on parts and other applications requiring repetitive back-and-forth movement. Rolling ring bearings inside the drive assure a backlash-free motion. Smooth reversal is achieved with a modified reversal mechanism that dampens the reversal action, dissipating forward momentum at the reversal points.

Right-Angle Gear Drives

Torque Transmission (Fairport Harbor, OH) has introduced a line of right-angle gear drives housed in glass-reinforced nylon, and are available in two model groups: RAB (standard right-angle drive) and MAD (for miniature angle drives). Both models feature one or two inputs and 1:1 or 2:1 gear ratios. RAB gear drives measure 3-21/32 × 3-15/16 × 1-1/4" deep and weigh 12 ounces. They employ shielded, lubricated, hardened steel ball bearing and gears, and are rated at 1600 RPM and 1/3 horsepower maximum speed of 3000 RPM.

Control System Software

SERVOSHAFT motion system control software from Danaher Motion (Wood Dale, IL) enables users to run all three functions of a control system (SCADA function, PLC, and motion control) from their own computers. The software meets IEC standard 61131-3 and supports the SFC, FBD, LD, ST, and IL programming languages. An OPC server enables communication with each SCADA system, and the platform also supports data exchange with PROFIBUS and CANopen.
