Description

多组永磁调速系统
技术领域
本实用新型涉及永磁调速技术领域，特别涉及一种多组永磁调速系统。 
背景技术
目前工业中广泛应用的联轴机构多为刚形连接，由于系统运行情况的复杂多变，无论怎样保证严格的两轴对中，设备运行一段时间后都会产生振动，从而加速磨损，缩短设备寿命，对于生产环境的不利影响越来越大，传统的刚性联轴器由于直接刚性连接产生噪音和摩擦且又需要润滑，已不能满足未来科技发展的需要，取而代之的是磁性耦合结构，由此永磁调速器应运而生。永磁调速系统大多用永磁体产生磁场，磁场穿过气隙把主、从动轴耦合在一起，可通过调节气隙或永磁体相对面积来调节耦合磁场大小实现调速。 
发明内容
本实用新型的目的是提供一种多组永磁调速系统，克服现有技术的不足，采用四组永磁体耦合，在固定气隙的情况下提高传递效率，减少损耗。 
为解决上述技术问题，本实用新型的技术方案是： 
多组永磁调速系统，包括输入轴、输出轴、永磁铁和调节装置，输入轴上同轴设有内支撑环和外支撑环，内支撑环外周和外支撑环内周分别对应设有永磁体一和永磁体二； 
输出轴端部设有筒形转子，筒形转子外周和内周分别对应设有永磁铁三和永磁体四； 
输入轴和输出轴同轴设置，永磁体一与永磁体四之间、永磁体二与永磁体三之间分别形成气隙； 
输出轴上设有调节装置，所述调节装置包括滚动轴承一、齿条、齿轮和摆杆，滚动轴承一内圈与输出轴之间设有内套，滚动轴承一外圈与齿条相连接，齿条与齿轮相啮合，齿轮与摆杆通过滚动轴承二外圈相连接，滚动轴承二内圈与定位轴相连接。 
所述永磁体一、永磁体二、永磁铁三和永磁体四中单体均为弧形，圆周均匀排列，数量相同且为偶数，N、S极交替放置。 
输入轴上的永磁体一和永磁体二与输出轴上的永磁铁三和永磁体四相对平行放置且充磁方向相同。 
与现有技术相比，本实用新型的有益效果是：采用四组永磁体耦合，通过控制输入轴与输出轴上的永磁体的相对面积大小的变化，在固定气隙的情况下提高传递效率和功率，减少损耗，进而改变转矩和转速，达到调速的目的。

图2是图1中A-A剖视图； 
图3是图1中B-B剖视图。

具体实施方式
下面结合附图对本实用新型的具体实施方式作进一步说明： 
见图1、见图2、图3，是本实用新型多组永磁调速系统实施例结构示意图，输入轴1上同轴设有内支撑环2和外支撑环3，内支撑环2外周和外支撑环3内周分别对应设有永磁体一4和永磁体二5； 
输出轴6端部设有筒形转子7，由销子19定位，防止筒形转子7沿轴向滑脱，筒形转子7外周和内周分别对应设有永磁铁三8和永磁体四9； 
输入轴1和输出轴6同轴设置，永磁体一4与永磁体四9之间、永磁体二5与永磁体三8之间分别形成气隙10； 
输出轴6上设有调节装置，调节装置包括滚动轴承一11、齿条12、齿轮13和摆杆14，滚动轴承一11内圈与输出轴6之间设有内套15，滚动轴承一11随内套15转动，内套15与输出轴6之间设有销轴18，内套15可沿输出轴6轴向移动，滚动轴承一11外圈与齿条12相连接，齿条12与齿轮13相啮合，齿轮13与摆杆14通过滚动轴承二16外圈相连接，滚动轴承二16内圈与定位轴17相连接。这样齿轮13便可以围绕定位轴17转动。驱动摆杆14便可以旋转齿轮13带动永磁铁三8和永磁体四9沿轴向移动，从而改变永磁体相对面积大小达到调速的目的。 
永磁体一4、永磁体二5、永磁铁三8和永磁体四9中单体均为弧形，圆周均匀排列，数量相同且为偶数，N、S极交替放置，此结构可大幅能提高系统效率。
