Problems solved by technology

Due to factors such as gear installation and manufacturing eccentric error, gear machining accuracy and other factors, the load may not be completely evenly distributed, so the characteristics of power splitting cannot be fully reflected, and it will also cause vibration and noise of the system and affect the service life.

Abstract

The invention discloses a flexible gear ring and a planetary gear system with the flexible gear ring. The flexible gear ring is of a wavy structure, and the wavy structure is used for adjusting the flexibility of the flexible gear ring. The planetary gear system with the flexible gear ring comprises a sun gear and a planet gear. The planetary gear system is characterized by further comprising a flexible gear and a sleeve, the flexible gear is connected with the sleeve, the flexible gear is engaged with the planet gear, and meanwhile the planet gear is engaged with the sun gear; and the flexible gear is of a wavy structure, and the wavy structure is used for adjusting the flexibility of the flexible gear ring. The flexible gear ring and the planetary gear system with the flexible gear ring are widely applied to planet gear transmission in the fields of helicopter main retarders and inner reduction gearboxes of aircraft engines, and meet the requirements for low weight and high reliability of aircraft products. The structure of the flexible gear ring is adjustable to adapt to needs for structures with different flexibilities, uniform load of the planetary gear system and damping of the system are facilitated, and the reliability and the stability of the planetary gear system are improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, in particular to a flexible ring gear and a planetary gear train with the flexible ring gear. Background technique [0002] Planetary gear transmission is widely used in various transmission fields such as aviation, ships, automobiles, wind turbines and heavy machinery. Compared with ordinary gear transmission, planetary gear transmission has unique advantages such as large transmission ratio, compact structure, high transmission efficiency, large carrying capacity and stable transmission. But to realize these advantages, the planetary gear load distribution should be as even as possible. Due to factors such as gear installation and manufacturing eccentric error, gear machining accuracy and other factors, the load may not be completely evenly distributed, so the characteristics of power splitting cannot be fully reflected, and it will also cause vibration and noise of the system,...
