Zero-Max Counter-Rotating 90-Degree Gearboxes

Counter-Rotating Gearboxes have a T-style design with two output shafts on the same axis and one input shaft at 90° from the outputs. Counter-Rotating Gearboxes are unique in that the two output shafts rotate in opposite directions simultaneously. This creates an ideal counterbalance and offers a different rotational direction than standard 90-degree gearboxes. We also offer a line of IP65 Rated Counter-Rotating Right-Angle Gearboxes for applications in wet and/or corrosive environments.
Zero Max’s counter-Rotating Spiral Bevel Gearboxes can be used in any power transmission application to change axis of rotation, improve load efficiency and reduce wear on mechanical components. Our skilled engineers can customize Counter-Rotating gearboxes to meet your specific application requirements. Additional benefits of Counter-Rotating Gearboxes include higher outputs and performance with smoother operation. The Crown design allows for changes in axis of rotation along with minimal backlash.

Counter-Rotating Vs. Standard 3-Way 90-Degree Gearboxes

While Counter-Rotating Gearboxes offset slightly more vibration than standard 3-Way gearboxes, the primary benefit of Counter-Rotating Spiral Bevel Gearboxes is that they offer two output shafts with different rotational directions – unlike the standard 3-way gearbox where the output shafts are physically connected together. See the Crown Drive Catalog for a rotational diagram.

Counter-Rotating Gears Deliver Smooth, Quiet, and Dependable Power

Counter-Rotating 90 degree Mitre gearboxes are designed to improve the efficiency and longevity of mechanical components and allow for increased output. The counterbalanced rotating gearbox helps offset vibrations to provide improved stability in mechanical drive systems. The fully enclosed design ensures that the internal gears can’t get out of alignment, jam up or become contaminated by debris. Additionally, the compact cast aluminum housing of Crown Gear gearboxes is designed for maximum strength and heat dissipation.

Counter-Rotating Right Angle Gearboxes feature premium hardened spiral bevel gears and non-magnetic stainless-steel shafts. The spiral bevel gears that Zero-Max uses offer superior strength and durability compared to straight bevel gears. Spiral bevel gears also allow for Counter-Rotating Gearboxes to deliver smooth, quiet, dependable power.
