Description
Technical Field
The invention relates to a gear transmission structure, in particular to a gear with an internal cooling lubricating system and a gear transmission mechanism.
Background
Engagement refers to a driving relationship between two mechanical parts, called engagement drive. Gear transmission is the most typical meshing transmission, and is also one of the most widely used transmission forms. According to different transmission principles, straight-tooth gear meshing transmission and helical gear meshing transmission are available. The gear meshing transmission has the characteristics of large application range, higher transmission efficiency, long service life, stable transmission, high reliability, capability of ensuring constant instantaneous transmission ratio, capability of realizing two-shaft transmission with various position requirements and the like, and is widely applied to modern mechanical transmission. It is composed of a driving gear, a driven gear and a frame. The motion and power of the driving wheel (shaft) are transmitted to the driven wheel (shaft) through the meshing action of the gears, and the required rotating speed and torque are obtained. Because of the advantages of high transmission efficiency, accurate transmission ratio, large power range and the like, the gear mechanism is widely applied to industrial products, and the design and manufacturing level of the gear mechanism directly influences the quality of the industrial products.
However, the problem of failure of gear meshing transmission after long-term use is mainly that: tooth breakage, tooth flank fatigue pitting, tooth flank wear, tooth flank gluing, tooth flank plastic deformation, wherein both tooth flank wear and tooth flank gluing are caused by unclean or insufficient lubricating fluid. The main forms of the gear meshing lubrication method include the forms of periodically and manually adding lubricating oil or lubricating grease, oil immersion lubrication or oil spraying lubrication and the like, so that the stability of gear transmission and the service life of the gear are ensured. And the heat that traditional gear engagement transmission friction produced mainly relies on lubricating oil etc. to solve, and the cooling effect is not very good in heavy load transmission in-process, and too high meshing area temperature also can influence the viscidity of lubricating oil, and then leads to the lubrication effect unsatisfactory.
