A new series of RTX precision
planetary gearheads from Sterling Instrument feature high torque design and are offered in standard NEMA sizes
60 and 90. These 36 gearheads are identified as the S9160AMRTX and the S9190AMRTX Series and feature single, double and triple gear stage
configurations, optimized gear geometry, high torsional stiffness, captive,
bearing supported input pinion and they are sealed to extend service life.
Each of the two NEMA sizes is offered
in gear ratios ranging from 4:1 to 700:1 and their maximum input speed is 6500
rpm. Their single stage, double stage and triple stage minimum efficiencies are
95, 90 and 85 percent respectively. Operating temperatures range from -40 to
+121C. The housings are made of stainless steel, with anodized aluminum
mounting flanges. The output shafts are made of stainless steel and the gears
are made of alloy and stainless steel.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
