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.

Abstract: A servo and a robot with the servo are provided. The servo comprises a power input apparatus with a first output shaft, a deceleration apparatus, and a power output mechanism. The deceleration apparatus comprises a first-stage deceleration mechanism and a second-stage deceleration mechanism. The power output mechanism comprises a second output shaft and an output bearing fixedly installed on the second output shaft, wherein the second output shaft is an external spline output shaft. Through the external spline output shaft and the output bearing disposed on the power output mechanism, the servo could directly connect with an exterior component through the external spline output shaft, and the strength is improved. As a result, the friction between the servo and the exterior component is reduced, and the lifetime is therefore increased.

Abstract: An overload protection assembly includes a first gear of a servo, a second gear of the servo, defining a receiving space; and a clutch configured to coaxially couple the first gear to the second gear and transmit torque between the first gear and the second gear. The clutch includes an elastic member arranged around the first gear and received in the receiving space. The elastic member includes a number of protrusions at a circumferential surface thereof, and a number of recesses are defined in a lateral surface of the receiving space. The protrusions are used to be respectively engaged with corresponding ones of the recesses so as to couple the firs gear to the second gear when a value of the torque is less than a preset value, and disengageable from the corresponding ones of the recesses so as to disconnect the first gear.
