Helical bevel gearboxes sport cast-iron frames

The new IronHorse HBR series of helical bevel gearboxes from AutomationDirect combine a helical gearset with a bevel gearset to create an output that is perpendicular to the input. The gearboxes have a hollow shaft output and accept double or single shafts.

Dual and single output shaft kits are available from AutomationDirect.

Helical gears offer a smoother, quieter operation than most other gear types, the company says. The universally interchangeable compact design is said to ensure easy OEM replacement and provides flexible installation with C-face and TC-face inputs, perpendicular output and 6 mounting positions.

Five gearbox sizes support 56C up to 254/6TC NEMA motor frames and 6 ratios are available from 10:1 to 120:1.

The helical bevel gearboxes are sized to handle from 1 to 24 hp motors. The bevel gearboxes feature cast-iron (FCD45) one-piece housings and high hardness alloy steel (20CrMO) pinion and gears.
