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)).

I would like to introduce a video that explains, in a very clear and intuitive way, how a cycloidal gear with two disks operates. Cycloidal reducers are widely used in robotics, automation equipment, and various precision control systems, and this video offers an accessible look into their essential structure and working principles.

The video begins by outlining the basic components of a cycloidal gear. The system consists of a sturdy housing and an input shaft. Notably, the input shaft does not rotate the disk directly. Instead, an eccentric cam mounted on the shaft creates a slightly offset rotational motion. Because of this eccentricity, the disk does not rotate smoothly around its center; rather, it produces a characteristic wobbling motion. This oscillatory movement is then transformed back into a smooth rotational output through the internal mechanism, enabling the gear to deliver high torque and precise speed reduction.

A particularly helpful part of the explanation is why two cycloidal disks are used in most designs. The video makes it clear that this dual-disk configuration helps reduce vibration and minimize torque ripple. Torque ripple refers to uneven transmission of force similar to how a bicycle pedal feels harder to push when it is vertical and easier when it is horizontal. By arranging two disks symmetrically, the vibrations generated by each disk cancel one another out. As a result, the system produces a much more uniform output, which is crucial for applications that require smooth and accurate motion.

The video also briefly explains how the gear ratio is determined. The number of lobes on the cycloidal disk defines the reduction ratio, and the final output motion is generated through output pins that fit into holes in the disks. In the example shown, the input shaft must rotate 49 times for the output to rotate once, and the output turns in the opposite direction of the input. counterclockwise when the input rotates clockwise.

This video is an excellent resource for anyone wishing to understand the fundamentals of cycloidal gear mechanics, even without prior familiarity. If you are curious about how mechanical motion is transformed into high torque and stable rotational output, I highly recommend watching the video and following along with the explanation.

Recommended Reading

For those who would like a deeper understanding, I also recommend the article titled “Cycloidal Gearbox Design: Principles, Structure, and Working Mechanism.” It provides a more structured explanation of the design principles and structural characteristics of cycloidal reducers, and when viewed together with the video, it will help clarify the overall operating mechanism even further.
