RV Cycloidal Gearboxes
RV (Rotary Vector) cycloidal gearboxes use an eccentric input shaft that causes a cycloidal disc to orbit within a ring gear.This orbital motion is then converted into a high-torque, low-speed output rotation. The main components of an RV cycloidal gearbox are the eccentric input shaft, the cycloidal disc, the ring gear, and the output shaft.The eccentric input shaft causes the cycloidal disc to orbit within the ring gear, creating a high-torque, low-speed output rotation.The rolling contact between the cycloidal disc and the ring gear results in a smooth, low-vibration motion.

FAQs about this Reducers
- How to measure RV gearbox moment rigidity? Apply pure bending moment at output flange. Measure angular deflection with laser encoder. Rigidity = Moment / Deflection (Nm/arcmin). - Why does RV gearbox require two cycloidal discs? One disc creates unbalanced radial force. Two discs with 180° offset cancel vibration and double torque capacity. - Which lubricant suits RV cycloidal gearboxes? ISO VG 68 to 220 synthetic oil with extreme pressure additives. Oil viscosity depends on input speed and operating temperature. - How to calculate RV gearbox reduction ratio? Divide input helical gear teeth by output pin carrier teeth. Multiply by cycloidal stage ratio. Formula: Ratio = (Z_helical_in / Z_helical_out) × (Z_pins / (Z_pins - Z_lobes)).
