Spur ovoid gear range expanded with new models


torque rated models that feature ultra- polymer gears and 4-point mounting with ball race front and rear support bearings – for competitively priced, high performance and low-noise miniature power transmission and positioning applications. The new 312, 332 and 362


R


models offer output torques of 1.3Nm, 3.0Nm, and 5.0Nm respectively and combine to bridge the performance gap between Rotalink’s entry level spur-ovoid gearboxes and its advanced, higher power spur-planetary ovoid models. 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 well proven 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 polymer gear materials on steel


shaft offer a higher power density than steel gear equivalents. www.rotalink.com
