Right angle gearboxes are used throughout dozens of industries in hundreds of applications that require a reliable transfer of speed or power. They're versatile, but the name can be a bit of a misnomer — the “right” in "right angle" comes from their 90-degree angle — but they can be right- or left-facing. If your application demands a right angle gearbox, it’s important to know if your design calls for a left-hand or right-hand rotation.
Right-Hand or Left-Hand Rotation
The main differentiation between the right-hand and left-hand versions of right angle gearboxes is the rotation of the gear drives.
For example, a bottom gear in both left- and right-hand rotations turning clockwise would have the top gear turning counterclockwise for left-hand rotation, and clockwise in the right-hand rotation.
With many standard types and sizes are available, and the ability for specialty shaft configurations, ensuring the right angle gearbox for your application is key. Having multiple mounting options also helps simplify your design considerations.
