Problems solved by technology

Such a speed-up device has the following problems: the inner ring gear is difficult to process, especially when the diameter is large and helical, the requirements for processing equipment are very high, resulting in high manufacturing costs; between the first and second stage star wheels The coaxial connection will cause the parameters of the first and second two-stage transmissions to be related. For example, on the basis of ensuring the strength of the star wheel, increasing the speed ratio of the first stage will lead to an increase in the outer diameter of the second stage. The two-stage speed increase ratio will lead to an increase in the outer diameter of the first stage, which will bring difficulties to design, manufacture and assembly; in addition, the coaxial connection will also limit the structural arrangement and power output mode of the second-stage star gear transmission

Abstract

The invention relates to a gear transmission device and a wind motor increase gear, comprising adjacent 2-grade star gear transmission devices, wherein the first-grade star gear corresponds to the second-grade star gear and is connected with the second-grade star gear through a first torque transmission device; the rotation axis of at least one first-grade star gear and the corresponding second-grade star gear are non-collinear, and the first-grade star gear and the corresponding second-grade star gear, the rotation axis of which are non-collinear, are connected together through a universal shaft joint.

Description

technical field [0001] The invention relates to a gear transmission device and a wind power engine speed-up device, the gear transmission device includes adjacent two-stage star gear transmission devices and the wind power engine speed-up device includes a three-stage gear transmission device. Background technique [0002] Gear transmissions are widely used in various occasions, such as wind turbine speed increasing devices, which are used to amplify the speed of the impeller. The U.S. patent No. US6,420,808 B1 discloses a gear speed-up device for wind power engines, which includes a three-stage gear transmission device. In the first stage, that is, the low-speed stage, an internal ring gear is used to simultaneously drive a plurality of first stages. The first-stage starwheel rotates, the first-stage starwheel and the second-stage starwheel are connected through a transmission shaft and the rotation axes of the two are collinear, and the second-stage starwheel meshes with a...
