Crossed Axis Gearboxes

Click image to enlarge
Cross axis gearboxes, also called helical gearboxes, feature helical cut gear teeth that mesh simultaneously and distribute the load evenly, reducing wear on individual teeth.  The angled teeth also create a smoother transition for reduced noise and vibration, even at high speeds and loads.
 
Crossed axis helical gearboxes are a common type of gearbox for vehicle and equipment transmissions. These devices use bearings to support the thrust load, enabling them to generate large amounts of thrust. When mounted to perpendicular shafts, helical gearboxes can be used to adjust the rotation angle by 90°.

Precision Helical Gear Reducers Built for High Performance

Ondrives.US has been designing, engineering, and manufacturing high performance crossed axis helical reduction gearboxes for decades. Our compact crossed axis gearboxes produce an output at 90° from the input, and are manufactured with anodized aluminum housings, hardened alloy steel input gears, and hardened alloy steel or aluminum-bronze output gears (varies by model). Precision manufacturing ensures superior helical gearbox performance and reliable service in even the most demanding applications.

High-Efficiency, Low Backlash Crossed Helical Gears

Our reliable, high-performance E Series right angle helical gear boxes are available in numerous sizes and configurations to meet your application requirements. E Series 90-degree crossed helical gears deliver output torque values as high as 62 Nm, with minimal backlash.
 
E Series right angle helical gear boxes (E and EA models) come with a variety of gear ratios (1:1 to 40:1) and input/output shaft sizes, making it easy to find the right model for your needs. All crossed axis gearboxes provide high efficiency (up to 94% at 1,000 RPM) and low backlash (as little as ≤30 arc minutes).
