No ballscrews or belts on new electric drive.A novel servo-electric plasticating and injection system for presses up to 250 tons reportedly delivers more power and higher injection speeds with faster acceleration than conventional ballscrew and timing-belt arrangements. Introduced at last fall's IPF (Itanium Processor Family) See Itanium. show in Tokyo, Japan, the High Power High Speed system from Moog Inc Moog, is a worldwide designer and manufacturer of motion and fluid controls and control systems for applications in aerospace, defense, industrial and medical device markets. ., Industrial Controls Div., East Aurora, N.Y., incorporates an unusual-looking actuator A mechanism that causes a device to be turned on or off, adjusted or moved. The motor and mechanism that moves the head assembly on a disk drive or an arm of a robot is called an actuator. See access arm. of a non-linear, low-friction design that uses no ballscrews nor belts, coupled with a high-torque, direct-drive AC servomotor ser·vo·mo·tor n. A motor that controls the action of the mechanical device in a servomechanism. [French servomoteur : Latin servus, slave + French moteur, motor . The actuator emits relatively little heat and allows for long hold times at high pressure with minimal power consumption. The closed-case design requires no lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of and is designed to operate for more than 30,000 hr (mean time between maintenance). The unit is designed for screw sizes of 50 or 56 mm diam. and accommodates injection strokes up to 200 mm. Maximum injection rate is 1478 m[m.sup.3]/sec or 600 mm/sec and max. injection pressure is 36,250 psi. Screw speed is up to 320 rpm. Acceleration response time is just 30 millisec. Injection power is rated at 400 hp. Tel: (716)-652-2000 * PT Direct: 715ZD [ILLUSTRATION OMITTED] |
