摩擦耦合器设计正文解析

摘要

本设计的题目——反馈控制轴向摩擦偶合器，是一个全新的课题，在国内外算得上是一种比较先进的产品，本设计是在无反馈轴向摩擦偶合器的基础上，为了获得更好的软启动效果而设计的一种新产品。同时，它具有与传统的硬启动相同的承载能力。因此本方案具有很好的发展前景。

本文的主要任务是整体结构的合理设计，包括摩擦元件的设计计算，各个传动部件的设计等。另外选择摩擦性能较好的摩擦材料对本次设计来说显得尤为重要，是关系到成败的关键因素。还要对各个传动和链接元件进行强度校核。从而使得该方案具有较好的可行性和实用性。

为了便于实现反馈控制，本方案采用主动级相对于反馈级对称布置的结构，主动级在两侧，中间是反馈级。在启动时采用离心式压紧，在径向均匀布置的带有锥面的离心块（与锥面摩擦盘配合）在主、从动机达到一定转速时将主动级和反馈级离心块甩出，产生径向位移的离心块同时在锥面间产生轴向位移，这样就将主动级机摩擦片和从动机摩擦片挤紧，主、从动机结合并传动。离心块采用圆柱螺旋压缩弹簧复位。个摩擦片和摩擦盘上带有花键槽。从动轴为花键轴，固定反馈级离心块的锥面圆盘可以在花键轴上滑动，使得其两侧的摩擦片分担相等的负载，杜绝了两边承载不均匀的现象。

Abstract

This design topic, feedback control axial frictional couplers, is a brand-new topic at home and abroad, is one of the more advanced product, the design is in no feedback axial frictional couplers, on the basis of the soft start to get better effect and design of a kind of new products. At the same time, it is the same with the tradition of hard start bearing capacity. Therefore, this scheme has the very good prospects for development.

This is the main task of the whole structure reasonable design, including friction components design calculation of various components of transmission, etc. Another choice friction properties of the friction material with good design, it is particularly important to the success of the relationship is the key factor. For each drive and links to check intensity components. So that this scheme has good feasibility and practicality.

In order to facilitate this scheme, realize the feedback control using active level relative level structure of feedback symmetrically arranged on both sides, active levels, feedback. CHKNTFS using centrifugal tightly in radial layout, the surface with centrifugal block (and cone friction disc in the Lord, with) from the motivation to certain speed will actively and feedback level and produce centrifugal blocks of radial displacement between cone simultaneously in centrifugal block axial displacement, this machine will be active and friction level from the motivation, friction slices crowded, motivation and transmission from. The centrifugal cylindrical helical compression spring return. A friction slices and friction plate with flowers keyways. The driven shaft for spline, fixed feedback level of centrifugal disk blocks in the surface, make the spline sliding friction slices

on both sides share equal load bearing, eliminate the uneven phenomenon on both sides.

Keywords：Friction couplers；Centrifugal；Friction slices；Surface friction disc；Reposition spring
