Problems solved by technology

However, these solutions only address the imbalance between different types of gears. There are not many solutions to the imbalance of the herringbone gear itself. The current solution is to improve the machining accuracy or assembly accuracy.

Embodiment Construction

[0020] Embodiments or embodiments of a variety of different implementation techniques disclosed will be disclosed. In order to simplify the disclosure, specific examples of each component and arrangement are described below. Of course, these are only examples, which are not limited to the scope of the invention. For example, the first feature described in the specification is formed above or above or above, and may include the first and second features to be formed by direct contact, or may be formed between the first and second features. Additional features of the additional feature thus can be contacted directly between the first and second features. Additionally, these disclosures may repeat the reference numerals and / or letters in different examples. This repetition is for the sake of brief and clear, it does not represent the relationship between the embodiments and / or structures to be discussed. Further, when the first element is described in connection with the second e...

Abstract

The invention aims at providing a fan engine, a star gearbox and a herringbone gear device. Rigidity of connection of a middle transition segment of teeth on the two sides of a herringbone gear is changed, flexible connection is achieved, and the aim of overcoming unbalance loading is achieved. A herringbone gear device comprises a first gear, a second gear and a gear shaft. The first gear is combined on the first shaft segment of the gear shaft through an elastic element, the second gear is combined on the second shaft segment of the gear shaft through the elastic element, the first gear and the second gear are axially fixed through the fastening part, the first gear and the second gear are axially spaced on the gear shaft and are combined to form the herringbone gear, and through deforming of the elastic element, the first gear and the second gear can rotate by a certain angle.

Description

Technical field [0001] The present invention relates to a human graphical gear. Background technique [0002] At present, each engine manufacturing company is competing to study gear transmission fan engines. It is mainly characterized by adding a set of stars to the booster gearbox between the fan and the boosting compressor, so that the fan and the boost compressor can be different. The speed of the speed is greatly improved the work efficiency of the engine. The core of this configuration is the planetary gearbox, which is mainly composed of a star wheel, a sun gear and a ring. In order to improve the intensity of the gear and the effect of impact load, in order to counteract the axial force, each gear is designed to teeth. At present, the human-character teeth of the gearbox are designed with both side tooth, that is, the corresponding retracting grooves or disconnected spacings in both side wheels, both sides of the gear rigidity. However, the rigid connection of the two-lat...
