Right Angle Bevel Gearbox
A right angle bevel gearbox is used when the drive has to change direction by 90°. Inside the housing, a bevel gear pair transfers rotation and torque from the input shaft to a perpendicular output shaft.
How it works
The input shaft turns the first bevel gear, which meshes with the mating gear on the output shaft, redirecting rotation by 90°. If a reduction ratio is built in, output speed decreases according to the ratio, and torque changes accordingly within the unit's ratings and the actual load.
Where you'll see them
Common placements include conveyors, packaging machines, and automation equipment where the motor axis and the driven axis need to sit at a right angle due to layout constraints.
Gear types
Right-angle sets may use straight, spiral, or Zerol bevel gears. Tooth form is typically chosen based on operating speed, load profile, and noise/vibration limits, along with the overall cost target for the machine.
What to check
Confirm rated torque (and allowable peak load), gear ratio, permitted input speed, shaft style (solid or hollow; keyed or clamping), mounting method, and lubrication requirements. Also verify motor/coupling interface dimensions and match the selection to the duty cycle and installation conditions.
