Miniature planetary/spur gearbox bring exceptional price/performance levels to OEMs.

  • First planetary/spur gear combination in compact ovoid format offers massive torque.

June 16, Crewkerne, UK - - - Rotalink, a world-leader in the design and manufacture of miniature transmission products, has launched two highly cost-effective planetary/spur gearboxes. Fabricated from advanced materials, dedicated gear profiles enable these unique compact units to deliver a massive 10 Nm of flexible torque at a highly competitive cost, significantly enhancing market opportunities for original equipment manufacturers. Key to the massive torque available in the planetary output stage is Rotalink’s unique gear tooth design, which also minimises noise and backlash. Power transfer to the stainless steel output shaft is maximised by the wide choice of ratios available in the spur input stage - up to 12800:1 - coupled with low friction standard front ball race and nylon or steel ball race rear bearings. The zinc-plated pressed steel case’s standard 4-point fixing gives OEMs solid but flexible fixing options.

Gearboxes are the Type 230, delivering up to 5Nm through input ratios from 25:1 to 1000:1, and the 260 delivering up to 10Nm through input ratios from 50:1 to 2000:1, both with alternative input ratios available up to 12800:1.The units are rated at 80°C at the gear case and are available with ac, stepper or dc motors, single or dual line encoders are optional across the range. With the introduction of these miniature gearboxes, Rotalink has successfully used its state-ofthe- art design capability and strategic manufacturing and sourcing to deliver the compact, costeffective product essential to 21st century motion control, automation and system integration OEMs. Typical applications include peristaltic pumps, dispensing equipment, vending machines and similar dosing/metering systems where air and/or liquid valve control is required; analytical instrumentation, semiconductor manufacturing plant and other applications where low cost and maximum performance are required.
