Description

与旋转器相关的装置
技术领域
本发明涉及一种与旋转器有关的方法。本发明还涉及一种与旋转器相关的装置。
背景技术
期望提供一种低构架或扁平的可靠的且功能可靠的旋转器。
发明内容
本发明的目的
本发明的目的是对于工作可靠性和支承有效性提供一种非常有利的解决方案。由于本发明包括的特征,本发明的目的被实现。根据本发明,提供了一种涉及旋转器的装置,所述旋转器用于由臂支撑的工作工具,其中所述旋转器包括定子和转子,其特征在于,所述装置包括用于附连工作工具的紧固环、在定子和转子之间的支承部以及设置在所述定子和所述紧固环之间的轴承,并且所述装置还包括驱动器,其设置在紧固环和转子之间的空间中并且与紧固环和转子接合,以用于将转子的旋转运动传递到紧固环和找到浮动位置从而消除支承部之间的应力干扰。
本发明的优点
根据本发明的装置涉及一种轴承(bearing),该轴承承受所有外部载荷的同时,位于所述旋转器定子和转子之间的普通轴承受到保护而免受外部载荷。这导致:当涉及传递例如径向力时,这两个轴承工作而不彼此干扰。本发明兼具技术和经济上的优点。
附图说明
图1是从上方所视的旋转器透视图。
图2是从下方所视的旋转器透视图。
图3示出了旋转器的第一竖直剖面。
图4示出了旋转器的第二竖直剖面。
图5和图6示出了根据本发明的驱动器的其他实施例。
具体实施方式
图1-4中所示的旋转器10包括定子20和转子30。转子30围绕旋转轴线A转动。
定子20包括定子上部20a、定子环20b和定子下部20c。这些部件20a-20c通过紧固件/螺钉21相互连接,如图4明显示出的。在使用旋转器10的过程中,根据上述目的定子20通过定子上部20a通常耦连至工作臂(未示出)或某一其他支撑部件。
转子30包括圆柱转子主体30a,圆柱转子主体30a设置在定子20的内部,如图3和图4明显示出。所示转子30是所谓的翼式转子,以便多个翼部件31布置成围绕转子主体30a的周边,以用于与定子环20和压力介质控制部件的相适应的内部形状相协作,从而使得转子30相对于定子20转动。用于该转子转动的作为转子支承部B、C的旋转支承表面设置在定子20的内部和转子30的外部之间。
所示旋转器10还包括旋转装置40,以用于将压力介质带到例如工作工具。旋转装置仅是示例性的,并没有详细描述,因为其是公知技术并且具有很多可能的实施方式。
根据本发明的外环/紧固环/固定板50安装在旋转器10的外部,如图1-4明显示出的。固定板50通过轴承D被定子20可转动地支撑,如图3和4最佳地示出的。轴承D在所示实例中的是由所谓的滚子轴承60构成的,其包括轴承内圈61和轴承外圈62,在这两者之间轴承滚珠63用于传递(impart)固定板50相对于定子20的转动。轴承内圈61通过紧固件/螺钉65锚固到定子上部20a,轴承外圈62通过紧固件/螺钉66锚固到固定板/外圈50。
固定板50设置成用于直接或通过中间紧固件(未示出)来支撑可转动的工作工具(未示出),因此多个固定孔51布置在固定板上以达到此目的。
轴承D的任务是传递作用在可转动工作工具(包括外部载荷)和定子20之间的力。因此以这种方式保护转子30免受这些主要有轴向特性的力。
所示的轴承D由滚柱轴承构成;然而,当然能理解的是,也能在本发明的框架内使用其它类型的轴承,例如滑动轴承。
根据本发明驱动环形式的驱动器80设置成用于将来自转子的旋转运动传递到固定板50。驱动器80包括用于驱动目的的两个外根部81、82和两个内根部83、84。驱动器80设置在固定板50和转子30之间的空间中,如图2-4明显示出的。外根部81、82分别与固定板50中的凹部91、92接合。内根部83、84分别与转子30中的凹部93、94接合。凹部91-94相对于相应的根部81-84具有一定的超出量尺寸,以便形成缝隙。这些缝隙使得驱动器80能横向于旋转器10的转动轴线A进行一定的横向运动,这使得旋转器能找到浮动位置,在该浮动位置发生旋转运动从转子30传递到固定板50,而不会产生引起不希望的支承力的横向力。根据本发明的驱动器的设置(其中驱动器是自动定心的)是非常有利的,因为这种驱动器的设置相对于旋转器的支承部之间的力的作用允许存在误差,以便支承部不彼此干扰。
两对根部81、82和83、84彼此呈直角设置,如图2所示,从而结合驱动器80的自动定心产生作用良好的力。
驱动器80消除了载荷从工作工具的固定板50传递到转子30,这使得转子30及其支承部(bearing)B、C的应力(stress)较小。即使在外部过载(例如,借助工作工具)的情况下,支承部B、C都受到保护而免受应力。
图5示出了关于驱动器180的一个简化的实施例,驱动器180安装在转子30的底部上。驱动器180包括指向外部的根部181,根部181配合在固定板50中的凹部内。在前面描述过的,在根部和凹部之间存在的缝隙即使在本例中也存在,以用于避免在转子和固定板之间传递径向力。
图6示出了驱动器280的另一个实施例,驱动器280附连到固定板50的底部。驱动器280包括向内指向的根部282,根部282配合在尺寸大的凹部内,这形成在转子30中的缝隙,从而使得转动力矩能被传递,同时消除径向力的传递。
根据本发明的驱动构件因此被设计成基于例如轴承间隙产生距离的径向变化。
本发明能通过替换功能上等同的部件而被容易地改变。
因此,本发明不局限于所示出和描述的,而是在以下权利要求的框架中能容易地做出修改和变型。
