The structure design of CVT machine of friction type
Abstract:
Under the action of some kind of control which can make the output of the machine spindle speed in two extreme CVT within the framework of the continuous variation of the transmission with the high-speed development of machinery, materials and processing technology and its demand is growing and is widely used and CVT transmission of the driving and driven by passing two shaft torque in the middle of the medium (mechanical components, fluid, electromagnetic flow, etc.), the two shaft linked directly or indirectly, and transfer power.When were related to the Lord, driven shaft to control, is the ratio between the two axis change (within the scope of the two extreme consecutive and arbitrarily change).With mechanical components as a medium for mechanical CVT, among which include friction and pulsation.CVT and constant transmission ratio transmission and continuously variable transmission (it's only a limited number of transmission ratio), compared to its advantage is the ability to work according to the need to continuous transformation rate within a certain scope, to adapt the demand of output speed and external load, the friction type CVT depend on mechanical transmission device for transmission, the friction between the steel material, processing technology level and the quality of lubricating oil is factors such as friction type mechanical stepless transmission the important guarantee of continuous development.This article through the consult literature and books, manuals, etc for the steel ring type stepless transmission principle and structure, the realization of the principle of variable speed drive structure research, and the friction type mechanical CVT structure design, can be directly as a guide for design documents or files for production and processing.
