摩擦式机械无级变速器结构设计
摘要
在某种控制的作用下，使机器的输出轴转速可在两个极值范围内连续变化的无级变速器传动随着机械、材质及加工工艺的高速发展和其需求量日益增多而得到广泛应用和发展。无级变速器的主动和从动两根轴通过传递转矩的中间介质（机械构件、流体、电磁流等）把两根轴直接或间接地联系起来并传递动力。当对主、从动轴的联系关系进行控制时，则两轴间的传动比发生变化（在两极值范围内连续而任意地变化）。用机械构件作为中间介质的为机械无级变速器，其包括摩擦式和脉动式。无级变速器与定传动比传动及有级变速传动（它只有有限的几种传动比）相比，其优点是能够根据工作需要在一定范围内连续变换速度，以适应输出转速和外界负载变化的要求，摩擦式机械无级变速器依靠传动元件之间的摩擦进行传动，钢材材质、加工工艺水平和润滑油料品质等因素是摩擦式机械式无级变速器不断发展的重要保证。本文通过查阅相关的诸多文献和书籍手册等进行钢环式无级变速器原理及其结构、变速原理的传动结构的实现的研究，并对摩擦式机械无级变速器进行结构设计，可直接作为设计文件或指导文件进行生产加工。

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.
