Description

采用空心杯电机结构的管状电机组件 技术领域
本发明属于电机设备技术领域,具体涉及一种采用空心杯电机结构的管状电机组件。
背景技术
随着机电行业的迅猛发展,电机已经广泛的应用在我们目前的生活中,例如, 管状电机作为驱动装置具有结构紧凑、转矩大、转速慢等优点,故管状电机越来越多地应用到电动完成升降运动的卷帘门窗、遮阳系统、投影屏幕等产品中。由于管状电机的电机轴转速过快,为了便于使用一般会在管状电机上设置减速器,从而使得输出轴的转速满足正常使用需要。现有的直流管状电机一般为普通稀土或铁氧体电机,即有转子铁芯、磁瓦贴于机壳等结构特点。现有的管状稀土或铁氧体马达存在着诸多不足,例如:1、有转子铁芯,转子铁芯质量大,使得转子在启动和停止时响应速度慢、能耗高、振动大,对零部件的损伤较严重,使得整机的寿命受到限制;其次,转子铁芯在磁场中会产生涡流,会导致马达发热、能耗高、效率低。2、磁瓦(永磁铁)固定在在机壳上,磁瓦(永磁铁)必须具备一定的厚度,在马达外经一定的情况下,马达转子的外经尺寸会受到很大的限制,从而使得马达的输出力矩受到很大限制。另外,现有的管状电机的减速器减速比无法满足需求,结构不够紧凑,传动过程稳定性差,这些问题都给现有管状电机使用时造成了极大的不便。
技术问题
为了解决现有技术存在的不足,人们进行了长期的探索,提出了各式各样的解决方案。例如,中国专利文献公开了一种管状电机行星减速器[200720184522.7],包括太阳齿轮、内齿端盖、内齿套和内齿套座,其特征在于内有:一级支架主体,上述一级支架主体上有三个支架销子,支架销子上有一级行星齿轮,下端有齿轮;二级支架主体,上述二级支架主体上有三个支架销子,支架销子上有二级行星齿轮,下端有齿轮;三级支架主体,上述三级支架主体上有三个支架销子,支架销子上有三级行星齿轮,下端是输出轴。上述方案在一定程度上解决了现有管状电机的减速器减速比无法满足需求的问题,但是该方案依然存在着普通稀土或铁氧体电机的诸多不足,同时,该方案依然存在着其他不足,例如,传动稳定性差等。

更进一步地,如图1-2及图6-13所示,本实施例中电机主体的传动结构主要包括如下内容,这里的电机主体9一端通过马达连接座91和一级齿圈1一端相连,且电机主体9的电机轴92和设置在一级齿圈1内的一级行星齿轮组件2相连,一级齿圈1另一端通过刹车外套8和具有相互连接的二级行星齿轮组件4和三级行星齿轮组件5的二三级齿圈3相连,一级行星减速组件通过位于刹车外套8内的刹车结构和二级行星齿轮组件4相连,且三级行星齿轮组件5连接有延伸至钢管体94一端外侧的输出轴6,钢管体94远离具有输出轴6的另一端通过限位环98和盖体99相连。这里的盖体99上设有与外部轴相连的固定孔,还可以设置与控制线路板96或供电电池97相连的充电接口和数据接口等。
优选地,这里的刹车结构包括通过周向定位结构设置在刹车外套8内的刹车芯轴83,刹车芯轴83一端具有呈筒状的刹车筒部831,且刹车筒部831上套设有刹车扭簧84,刹车外套8内穿设有相互同轴设置的刹车主动件81和刹车被动件82,刹车主动件81与一级行星齿轮组件2的输出端相连,刹车被动件82与二级行星齿轮组件4的输入端相连,刹车主动件81具有两个主动爪部811,且刹车被动件82靠近刹车主动件81的一端穿过刹车芯轴83且具有两个被动爪部821,主动爪部811和被动爪部821一一相互错位设置且任意一个主动爪部811位于任意一个被动爪部821一侧,主动爪部811和被动爪部821之间设有当刹车主动件81周向转动时能使刹车扭簧84周向膨胀且刹车被动件82随刹车主动件81同步同向转动或当刹车被动件82周向转动时能使刹车扭簧84周向收紧且使得刹车被动件82周向止动的刹车控制组件。
具体来讲,这里的刹车控制组件包括形成于刹车扭簧84两端且径向向外弯折的弯折脚部841,刹车被动件82的两个被动爪部821中任意一个被动爪部821位于两个弯折脚部841之间,且两个弯折脚部841中任意一个弯折脚部841位于被动爪部821和主动爪部811之间,且被动爪部821靠近刹车被动件82的一端两侧分别具有沿被动爪部821宽度方向向外延伸且与主动爪部811一侧相抵靠的台阶821a,且被动爪部821远离具有台阶821a的一端外侧和主动爪部811之间形成供弯折脚部841穿入的活动间隙821b。这里的刹车扭簧84的两个弯折脚部841沿刹车扭簧84中心线方向的间距大小大于被动爪部821远离具有台阶821a的一端的宽度大小。
优选地,这里的刹车芯轴83包括与刹车筒部831同轴相连的芯轴环体832,芯轴环体832和刹车筒部831连为一体式结构,芯轴环体832周向内侧和刹车筒部831周向内侧相互连通从而形成芯轴通道833,周向定位结构包括若干设置在刹车外套8一端周向内侧的定位槽85,且各个定位槽85周向均匀分别设置且均沿刹车外套8轴向延伸设置,芯轴环体832周向外侧具有若干分别和定位槽85一一对应的定位凸块86,定位凸块86分别卡设在定位槽85内。
其中,一级行星齿轮组件2通过主动爪部811和被动爪部821传动至二级行星齿轮组件4,然后再通过三级行星齿轮组件5和输出轴6相连,这样提高了传动稳定性,同时,可以在刹车外套8内设置一个刹车芯轴83,刹车芯轴83上套设有刹车扭簧84,刹车扭簧84分别作用于主动爪部811和被动爪部821,这样实现在一级行星齿轮组件和二、三级行星齿轮组件之间设置刹车的目的。
具体来讲,如图14所示,当刹车主动件81周向转动时无论是正向还是反向转动均带动主动爪部811一起转动,主动爪部811均先与刹车扭簧84的一个弯折脚部841先接触,主动爪部811推动弯折脚部841时使得使刹车扭簧84周向膨胀,刹车扭簧84内径变大,使得刹车扭簧84与刹车芯轴83松开,当主动爪部811继续转动时带动弯折脚部841在活动间隙821b内移动,进一步将刹车扭簧84内径变大直至主动爪部811一侧抵靠在被动爪部821的台阶821a上,实现刹车扭簧841处于膨胀状态下主动爪部811带动被动爪部821同步转动,实现动力向下一级转动,当刹车被动件82周向转动时无论是正向还是反向转动均带动被动爪部821一起转动,在被动爪部821的台阶821a未与主动爪部811一侧接触前,被动爪部821先带动刹车扭簧84内径变小,使得刹车扭簧84与刹车芯轴83抱紧,刹车扭簧84与刹车芯轴83之间产生很大的摩擦力,实现整个刹车过程,从而使得动力不会向刹车主动件81传递。
其中,本实施例中的刹车部分,刹车芯轴83与刹车外套8固定不动。刹车扭簧84与刹车芯轴83过盈配合,刹车主动件81和刹车被动件82各有两个角,在转动时,电机轴92的力矩通过一级行星齿轮组件2传递给刹车主动件81,不论是顺时针旋转还是逆时针旋转刹车主动件81都会使得刹车扭簧84内径变大,使得刹车扭簧84与刹车芯轴83松开,从而使得力矩传递给被动件82进而传递给二级行星齿轮组件4和三级行星齿轮组件5,最终由输出轴6传递出去。而当力矩从输出轴6传递给二级行星齿轮组件4和三级行星齿轮组件5进而传递给刹车被动件82,不论是顺时针旋转还是逆时针旋转,刹车被动件82都会使得刹车扭簧84内径变小,使得刹车扭簧84与刹车芯轴83抱紧,刹车扭簧84与刹车芯轴83之间产生很大的摩擦力,因刹车芯轴83固定不动从而使得力矩不能继续传递到一级行星齿轮组件2,故而起到刹车的效果。
其中,这里的刹车主动件81包括通过第一转动轴承815同轴转动设置在刹车外套8一端周向内侧的主动芯轴812,且主动芯轴812一端具有主动件连接孔8121,另一端同轴连接有主动环体813,且主动爪部811分别对应设置在主动环体813的周向外侧,在主动环体813远离主动芯轴812的一端同轴连接有转动筒体814。
进一步地,这里的刹车被动件82包括通过第二转动轴承827同轴转动设置在刹车外套8远离主动芯轴812的一端周向内侧的被动芯轴822,被动芯轴822一端具有被动件连接孔8221,另一端贯穿于芯轴通道833内且同轴连接有被动筒体823,且被动爪部821分别对应设置在被动筒体823的一端周向外侧,且被动筒体823一端具有供转动筒体814插入的转动孔824,另一端具有限位环体825,且刹车筒部831周向内侧具有与限位环体825相抵靠的环形限位台阶826。
其中,一级行星齿轮组件2包括一端具有与主动件连接孔8121相连的一级行星输出轴211的一级行星架21,一级行星架21周向均匀设置三根一级行星滚针22,且一级行星滚针22上均具有一级行星轮23,且一级行星轮23周向均匀分布且均与电机主体9的电机轴92相连,且一级齿圈1周向内侧具有若干和一级行星轮23相啮合的一级齿牙24,且一级齿牙24和一级行星轮23均为斜齿结构。
同样地,这里的二级行星齿轮组件4包括一端具有二级行星输出轴411的二级行星架41,二级行星架41另一端周向均匀设置三根二级行星滚针42,且二级行星滚针42上均具有二级行星轮43,二级行星轮43周向均匀分布且均与和被动件连接孔8221相连的二级中心轮44相啮合,且二三级齿圈3周向内侧具有若干和二级行星轮43相啮合的二三级齿牙45。
这里的三级行星齿轮组件5包括一端具有输出轴6的三级行星架51,三级行星架51另一端周向均匀设置三根三级行星滚针52,且三级行星滚针52上均具有三级行星轮53,三级行星轮53周向均匀分布且均和二级行星输出轴411上的小齿轮啮合,且二三级齿圈3周向内侧的二三级齿牙45分别和各个三级行星轮53相啮合。
为了实现将一级齿圈1和二三级齿圈3分别定位在刹车外套8两端,这里的刹车外套8通过周向固定结构7设置在一级齿圈1和二三级齿圈3之间。优选地,周向固定结构7包括设置在刹车外套8一端周向外侧的第一凹凸定位组件71,一级齿圈1一端周向内侧设有与第一凹凸定位组件71相对应的第一凹凸配合组件72,第一凹凸定位组件71和第一凹凸配合组件72相互卡接且周向定位,刹车外套8另一端周向外侧的第二凹凸定位组件73,二三级齿圈3一端周向内侧设有与第二凹凸定位组件73相对应的第二凹凸配合组件74,第二凹凸定位组件73和第二凹凸配合组件74相互卡接且周向定位,优选地,这里的第一凹凸定位组件71、第一凹凸配合组件72、第二凹凸定位组件73和第二凹凸配合组件74可以采用定位齿结构,通过齿和齿的相互插接实现周向定位。
