Spur Ovoid Gearbox

Rotalink has broadened its spur ovoid gearbox range with three new progressively sized and torque rated models that feature ultra-polymer gears and 4-point mounting with ball race front and rear support bearings for low-noise miniature power transmission and positioning applications. The new 312, 332 and 362 models offer output torques of 1.3 Nm, 3.0 Nm, and 5.0 Nm respectively. They offer users an increased and more flexible choice of standard range gearboxes with nominal ratios that range from 6:1 to around 800:1 depending upon the model. In particular the lower ratios suit applications where a moderate motor input speed is desirable with the benefit of lower noise and increased service life. The zinc plated pressed steel gearbox case used in the new models all feature Rotalink's characteristic and unique 4-hole fixing. This mounting arrangement provides higher output shaft stiffness and smoother speed than traditional 2-hole fixings which have a propensity to deflect or oscillate under load. The new models also feature high-strength and light-weight ultra-polymer gear materials on stainless steel shafts which contribute to a higher power density rating than steel gear equivalents, with the added benefit of low mechanical noise and extremely competitive pricing. Supported with large front and rear ball race bearings, the output shaft diameters are 6 mm, 8 mm and 10 mm.
