Standalone planetary reducers feature a floating sun gear and a ring gear around three planetary gears.
Features & benefits
Unlike planetary gears that are fixed in place, the sun gear has a toothed central spline loosely fitted onto the shaft spline, creating a floating sun gear
Primary advantage of floating sun gear is quieter operation; when clamped to the motor shaft, the sun gear rattles if tolerances vary at all, indicating that gearbox is out of tolerance
Standard configuration allows mounting to any motor with a NEMA 23 or 34 input flange
Standard design contains powdered metal gears; optional rugged design with steel gears withstands harsh conditions
