Coaxial-output rotation and revolution transmission method and device

Abstract

The invention relates to a coaxial-output rotation and revolution transmission method and device. The axis of a power output shaft and the axis of a crank of a power input shaft coincide; the power output shaft performs revolution around the axis of a spindle of the power input shaft, and the revolution speed is equal to the rotating speed of the power input shaft. Main power of the power input shaft is subjected to superposition of a transition gear train and a K-H-V small-tooth-difference planetary gear train, so that the power output shaft performs rotation movement which is equal to the power input shaft in speed and opposite to the power input shaft in direction; meanwhile, a rotation-revolution thrust bearing coaxial with the power output shaft and a thrust bearing coaxial with the spindle of the power input shaft are connected in series to bear axial loads. The coaxial-output rotation and revolution transmission device is mainly composed of the power input shaft, the transition gear train, the K-H-V small-tooth-difference planetary gear train, the series thrust bearing set, the power output shaft and the like. The device can form an extruder by being combined with an eccentric-rotor volume pulsation deformation plasticized transport device.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a transmission method and device for coaxial output rotation and revolution. Background technique [0002] Modern mechanical transmission is widely used in mechanical engineering, mainly referring to the use of mechanical means to transmit power and motion. At present, most mechanical transmission mechanisms are single-input and single-output transmissions. However, in some special fields of mechanical engineering, the actuator is required to achieve coaxial rotation and revolution. For example, in the field of petrochemical industry, volumetric fluid conveying machinery mostly adopts a positive displacement pump structure, which uses the rotation and revolution of the rotor in the inner cavity of the stator to realize the volumetric fluid conveying process; in the field of polymer material processing machinery, some plasticizing conveying The motion device requ...

AI Technical Summary

Problems solved by technology

[0003] In traditional mechanical engineering devices, the rotor often needs to achieve rotation and revolution at the same time, but this rotation and revolution is caused by the coordinated movement of the actuator stator and rotor, while the transmission system of the construction machinery device is only composed of universal couplings. The device passively accepts the compound motion of the rotor shaft, but cannot actively output the rotation and revolution

When the traditional universal coupling-based transmission mechanism is connected to the rotation and revolution movement actuator, it can only rely on the meshing of the rotor and the stator to passively realize the revolution movement, and most of the axial load generated during transportation requires The stator and rotor bear the burden, and the overall stability of the transmission system is low, causing problems such as unstable operation of the rotor, wear and deformation of the inner cavity of the rotor and the stator, etc.

At present, there is no transmission device that coaxially outputs rotation and revolution and can bear axial load
