Embodiment Construction

[0010] The content of the present invention will be further described below in conjunction with it.

[0011] See attached figure 1 , the continuously variable constant speed transmission shown in this embodiment consists of a speed sensor A; a single-chip microcomputer or a computer B; a continuously variable transmission controller C; a continuously variable transmission D; an input shaft 1; 4; Outer center wheel 5; Center shaft 6; Umbrella wheel or other reversing mechanism 7; CVT input shaft 8; CVT output shaft 9. Wherein the output shaft 9 and the central shaft 6 are a shaft.

[0012] First, the external input is input through the input shaft 1, and then the input shaft 1 pushes the planetary gear 3 to revolve through the tie rod 2. The outer center wheel is driven by the planetary wheel 3 to rotate, and is connected to the input shaft 8 of the continuously variable transmission through the bevel wheel 7 . The rotation of the planetary gear 3 can be divided into two par...

Abstract

A stepless constant and variable speed gear and a method relate to a stepless speed regulating device and a realizing method, in particular to a device which adopts a differential gear train as well as stepless speed change to turn instable input into constant output. A shaft of an inner center wheel of the differential gear train is taken as an output shaft, a shaft in the differential gear train which is connected with a track rod is taken as an input shaft, the input shaft can drive a planetary wheel to rotate in virtue of the track rod; in order to achieve the purpose that the output shaft can constantly output rotating speed, the speed ratio of the relative rotation speed of the inner center wheel and an outer center wheel can be adjusted by a stepless speed variator according to the rotating speed of the input shaft to realize the constant speed output of the output shaft; furthermore, as the input shaft is connected with the output shaft in a transmission way by the planetary wheel, large-power output can be achieved. The differential gear train constant and variable speed gear designed according to the technical proposal can be applied to wind power generation, and the like, and has extremely wide application.

Description

technical field [0001] The content of the present invention belongs to the technical field of mechanical engineering, and relates to a stepless speed regulating device and its realization method, in particular to a device which utilizes a differential gear train to perform stepless speed change from an unstable input to a constant output. Background technique [0002] Currently, there are very few transmissions that change an unstable input into a stable output. [0003] Considering that the differential gear train has been used for continuously variable speed rotation, since this device can continuously and smoothly change the speed under load, and the mechanism is not complicated, it is widely used in industry. There is a 2K-H type mechanism in the differential gear train, which is composed of three basic structures of two center wheels (2K) and a tie rod (H). The mechanism has two degrees of activity, and it must have two original moving parts to determine the movement, ...
