Abstract
The present disclosure provides a speed reduction device, a joint servo and a robot. The speed reduction device includes a driving device, a first stage speed reduction assembly and a second speed reduction assembly. The first speed reduction assembly includes a power gear and a face gear. The second speed reduction assembly includes a sun gear that rotates coaxially with the face gear, a planet gear set driven to rotate by the sun gear, a fixed gear, an output gear for outputting power and a fixed shaft. The speed reduction device uses the first speed reduction assembly and the second speed reduction assembly for power transmission and is compact in structure and has a high single stage transmission ratio.
Claims10
A speed reduction device comprising:
- a driving device configured to provide power and comprising an output shaft for outputting the power;
- a first stage speed reduction assembly configured to change an output direction of the power, the first stage speed reduction assembly comprising a power gear that is mounted on the output shaft and rotates together with the output shaft, and a face gear that engages the power gear, and a rotation direction of the face gear being perpendicular to a rotation direction of the power gear, and
- a second stage speed reduction assembly securely mounted on a surface of the face gear that has gear teeth, the second stage speed reduction assembly comprising a sun gear that rotates coaxially with the face gear, a planet gear set that engages the sun gear and is driven to rotate by the sun gear, a fixed gear that is mutually engaged with the planet gear set and configured to prevent the planet gear set from idling, an output gear that is mutually engaged with the planet gear set and outputs the power, and a fixed shaft that passes through the face gear, the sun gear and the planet gear set in sequence and is fixed to the output gear.
