Pure electric swing cylinder

Abstract

The utility model belongs to swing cylinder technical field discloses a kind of pure electric swing cylinder.The pure electric swing cylinder includes: cylinder body, cylinder body includes the first inner ring gear and second inner ring gear of connection arrangement, and the inner wall of first inner ring gear is equipped with inner tooth;Output shaft, output shaft is coaxially rotationally connected in one end of first inner ring gear;Electric drive component, electric drive component is built into second inner ring gear, and electric drive component includes motor output shaft, and motor output shaft drives output shaft rotation;Speed reduction component, speed reduction component is built into first inner ring gear, and speed reduction component is arranged between motor output shaft and output shaft;Speed reduction component includes several speed reduction gear sets, and the torque of several speed reduction gear sets is gradually increased in turn, and the speed reduction gear set of minimum torque is close to motor output shaft setting.The utility model improves the stability of torque output and the overall life of swing cylinder by optimizing the design of speed reduction part, increasing the number of planetary gear, improving brake system and control system, so that swing cylinder action is more stable.
