TRANSMISSION METHOD AND DEVICE FOR COAXIALLY OUTPUTTING AUTOROTATION AND REVOLUTION.

摘要

Disclosed are a transmission method and a device for coaxially outputting autorotation and revolution. The axis of a power output shaft (17) and the axis of a crank of a power input shaft (1) are coincided with each other. The power output shaft (17) revolves around the axis of a main shaft of the power input shaft (1), and the revolution speed equals to the rotation speed of the power input shaft (1). After the superposition of a transition gear train (A) and a K-H-V few-tooth-difference planetary gear train (B), a driving force of the power input shaft (1) enables the power output shaft (17) to generate the autorotation which has the same speed as that of the power input shaft (1) but in the opposite direction, and at the same time, a thrust bearing (19) coaxial with the power output shaft (17) is connected to a thrust bearing (18) coaxial with the main shaft of the power input shaft (1) in series to bear axial loads. The transmission device for coaxially outputting autorotation and revolution is mainly formed by the power input shaft (1), the transition gear train (A), the K-H-V few-tooth-difference planetary gear train (B), the thrust bearings (18, 19) connected in series, and the power output shaft (17), etc. The device can be combined with a plasticizing delivery device using an eccentric rotor and having pulsed volume deformation to form an extruder.
