相关申请的交叉引用
本申请要求于2018年6月11日提交的题为“INCREASED DURABILITY LINEARACTUATOR”的临时专利申请号62/683,331的优先权，该申请以其所公开的全部内容通过参引并入本文中。
技术领域
本公开总体上涉及线性致动器。更特别地，本公开总体上涉及用于更改另一平台的坡度的线性致动器。
背景技术
常规的线性致动器包括由推力轴承支承的可移动轴。当轴将力施加至另一物体时，推力轴承支承轴抵抗轴向载荷。具有由梯形(acme)螺杆驱动的轴的线性致动器具有旋转推力轴承，当轴受到轴向压力时，该旋转推力轴承允许梯形螺杆旋转。
侧向载荷或在垂直于轴的纵向轴线的方向上施加力会导致推力轴承过早失效。在具有梯形螺杆驱动的轴的线性致动器中，推力轴承的失效会导致梯形螺杆失效以及线性致动器卡住。
诸如跑步机、椭圆机和健身自行车之类的锻炼系统使用线性致动器来调节系统的坡度或倾斜度，从而为用户提供不同的锻炼体验。由于用户期望锻炼例程的种类更多，并且锻炼系统由于越来越大的运动范围而经历更频繁的调整，因此，线性致动器在轴上承受较大量的侧向载荷。
发明内容
在一些实施方式中，线性致动器包括马达、轴和壳体。轴具有纵向轴线，并且轴可以通过马达沿着纵向轴线移动。壳体通过定位在轴的至少一部分与壳体的一部分之间的圆锥滚子轴承来支承马达和轴。
在一些实施方式中，锻炼系统包括：基部；框架，该框架以可移动的方式连接至基部；以及线性致动器，该线性致动器定位在基部的至少一部分与框架的至少一部分之间，以将力施加至框架并且使框架相对于基部移动。线性致动器包括马达、轴和壳体。轴具有纵向轴线，并且轴能够通过马达沿着纵向轴线移动。壳体通过定位在轴的至少一部分与壳体的一部分之间的圆锥滚子轴承来支承马达和轴。
在一些实施方式中，支承线性致动器的轴的方法包括：通过线性致动器的轴接收径向力；将径向力传递至梯形螺杆；以及通过梯形螺杆将扭矩施加至圆锥滚子轴承。
提供本发明内容是为了以简化的形式介绍一些概念，这些概念将在下面具体实施方式中进一步描述。本发明内容既不意在标识所要求保护的主题的关键特征或必要特征，也不意在用于帮助确定所要求保护的主题的范围。
附加的特征和优点将在下面的描述中阐述，并且部分地将通过描述而变得明显，或者可以通过本文中的教示的实践而获知。本发明的特征和优点可以借助于本发明的各实施方式中特别指出的器械和组合来实现和获得。本发明的特征将根据以下描述和各实施方式而变得更加完全明显，或者可以通过下文中阐述的本发明的实践而获知。

具体实施方式
在根据本公开的线性致动器的一些实施方式中，致动器可以包括圆锥滚子轴承，该圆锥滚子轴承支承轴以加强轴抵抗侧向载荷。例如，常规的线性致动器具有定位在轴的基部处的衬套，以支承轴抵抗施加至轴的轴向载荷。衬套或其他轴向支承件可以提供轴向支承，但当线性致动器受到施加至轴的侧向力时可能会过早磨损。
图1是根据本公开的线性致动器100的立体图。线性致动器100包括马达102，该马达102构造成使轴104沿着轴104的纵向轴线106轴向地移动。马达102通过壳体108和套筒110连接至轴104。壳体108可以容纳一个或更多个齿轮、带、线缆或其他扭矩传递装置，以将扭矩从马达102传递至套筒110中的梯形螺杆。该梯形螺杆可以与轴104上的互补的表面特征相互作用，使得随着梯形螺杆的旋转，轴104沿纵向轴线106的方向移动。
图2图示了包括图1的线性致动器100的锻炼系统112。该锻炼系统112可以包括以可移动的方式彼此连接的基部114和框架116。线性致动器100可以以任何取向定向以通过机械联动装置来推动框架116、拉动框架116或向框架116施加力。基部114和框架116可以绕铰链118以枢转的方式彼此连接。在一些实施方式中，线性致动器100可以定位在基部114的至少一部分与框架116的一部分之间以在基部114与框架116之间施加力，从而改变框架116相对于基部114的坡度(或倾斜度)。在一些实施方式中，基部114和框架116可以具有包括0°、-5°、-10°、-15°或更小的下限值的运动范围，并且基部114和框架116的运动范围可以具有5°、10°、15°、20°、25°或更大的上限值。例如，基部114和框架116可以具有至少从0°至5°的运动范围。在其他示例中，基部114和框架116可以具有至少从-5°至15°的运动范围。在又一些其他示例中，基部114和框架116可以具有至少从-10°至20°的运动范围。在另外的示例中，基部114和框架116可以具有至少从-15°至25°的运动范围。在又一些另外的示例中，基部114和框架116可以具有至少-20°至25°的运动范围。
在一些实施方式中，锻炼系统112可以包括使用者可以通过其与锻炼系统112交互的一个或更多个计算装置120或其他接口。计算装置120与线性致动器100通信。例如，计算装置120可以允许使用者通过经由计算装置120手动选择坡度或倾斜度值来对框架116相对于基部114的运动进行控制。在其他示例中，计算装置120可以包含存储在其上的一个或更多个锻炼例程，所述一个或更多个锻炼例程在其中包括框架116相对于基部114的一个或更多个坡度值或倾斜度值。锻炼例程可以使计算装置120与线性致动器100通信，以使框架116相对于基部114移动并且改变框架116的坡度或倾斜度从而为使用者提供各种锻炼体验。
在一些实施方式中，计算装置120可以与具有特定于所选定的使用者的锻炼例程的用户简档进行通信或访问这些用户简档。可以与本文中所描述的原理兼容的用户简档数据库的示例包括可以通过www.ifit.com获得并且通过位于美国犹他州罗根市的ICON健康和健身股份有限公司(ICON Health and Fitness,Inc.)管理的iFit程序。在一些示例中，可以通过用户简档访问的用户信息包括使用者的年龄、性别、身体成分、身高、体重、健康状况、可以有助于确定用于使用者的合适的锻炼例程的其他类型的信息或其组合。此类用户简档信息能够通过iFit应用于计算装置120。
图3-1图示了根据本公开的线性致动器200的实施方式的侧视横截面图。该线性致动器200包括马达202，该马达202构造成通过梯形螺杆222使轴204沿着纵向轴线206移动。梯形螺杆222可以与位于梯形螺杆222与轴204之间的互补接合部224相互作用，使得当梯形螺杆222绕纵向轴线206旋转时，带螺纹的互补接合部224使轴沿着纵向轴线206并且相对于套筒210轴向地推进。尽管互补接合部224被示出为与轴204成一体，但是在其他实施方式中，互补接合部224可以定位在相对于轴204轴向地固定的螺母或其他中间部件上。梯形螺杆222由齿轮联动装置226驱动，齿轮联动装置226定位在壳体208内并且由马达202驱动。在其他实施方式中，从马达202到梯形螺杆222的联动装置可以包括用于将扭矩从马达202传递至梯形螺杆222的带、链、凸轮、杠杆或其他机构。
梯形螺杆222防止线性致动器200在使用期间反向驱动。特别地，锻炼系统、比如关于图2所描述的锻炼系统112在使用期间可能经受反复冲击，所述反复冲击可能会反向驱动滚珠丝杠。
在一些实施方式中，比如在关于图2所描述的锻炼系统112中，轴204可能经受在垂直于纵向轴线206的径向方向上施加的力228。通过力228施加至轴204的扭矩可以被传递至梯形螺杆222并且被传递至梯形螺杆222与壳体208和/或齿轮226的连接件。例如，力228可能通过在跑步机上跑步的使用者对锻炼系统(比如图2的框架116)的侧向冲击引起。在其他示例中，当锻炼系统以坡度或倾斜度定位时，力228可能通过由使用者和/或搁置在线性致动器200上的框架的重量施加的向下的力引起。
线性致动器200包括定位在轴204与壳体208之间的圆锥滚子轴承230。在一些实施方式中，圆锥滚子轴承230可以定位在梯形螺杆222的至少一部分与壳体208之间。例如，圆锥滚子轴承230可以定位在梯形螺杆222的肩部232与壳体208之间。轴204上的径向力228和/或轴向力可以传递至梯形螺杆222并且传递至圆锥滚子轴承230。圆锥滚子轴承230包括内座圈231、外座圈235以及定位在内座圈231与外座圈235之间的多个滚子233。
在一些实施方式中，圆锥滚子轴承230可以在纵向轴线206与圆锥滚子轴承230的轴承轴线236之间具有轴承角234。该轴承角234可以在以下范围内：该范围具有包括5°、10°、15°、20°、25°、30°、35°、40°、45°或其间的任何值中的任一者的上限值、下限值、或者上限值和下限值。在一些示例中，轴承角234可以大于5°。在其他示例中，轴承角234可以小于45°。在又一些其他示例中，轴承角234可以在5°与45°之间。在另外的示例中，轴承角234可以在5°与30°之间。在又一些另外的示例中，轴承角234可以是大约10°。圆锥滚子轴承230的轴承角234可以通过定向为接收相对于梯形螺杆222上的轴向力更多的径向力228或接收相对于径向力228更多的轴向力来影响线性致动器200的操作寿命。
线性致动器200可以包括相对于轴204在纵向上定位在圆锥滚子轴承230的另一边的第二轴承。例如，图3-1图示了滚珠轴承237，该滚珠轴承237定位在梯形螺杆222的越过齿轮226的末端端部处。当轴204经受侧向载荷时，滚珠轴承237可以为梯形螺杆222提供额外的支承。在其他示例中，圆锥滚子轴承230和滚珠轴承237可以互换，其中，滚珠轴承237邻近梯形螺杆222的肩部232。
在一些实施方式中，圆锥滚子轴承230能够支承以下范围内的轴向载荷：该范围具有包括500磅、750磅、1000磅、1250磅、1500磅、1750磅、2000磅或其间的任何值中的任一者的上限值、下限值或者上限值和下限值。例如，至少500磅的轴向力(即，沿纵向轴线206的方向)。在其他实施方式中，圆锥滚子轴承230能够支承700磅与2000磅之间的轴向力。在其他实施方式中，圆锥滚子轴承230能够支承1000磅与2000磅之间的轴向力。在其他实施方式中，圆锥滚子轴承230能够支承在1500磅与2000磅之间的轴向力。在其他实施方式中，圆锥滚子轴承230能够支承大约2000磅的轴向力。
在一些实施方式中，圆锥滚子轴承230具有小于1.5英寸的内径239。在其他实施方式中，圆锥滚子轴承230具有小于1.25英寸的内径239。在又一些其他实施方式中，圆锥滚子轴承230具有小于1.0英寸的内径239。在另外的实施方式中，圆锥滚子轴承230具有小于0.75英寸的内径239。在又一些另外的实施方式中，圆锥滚子轴承230具有小于0.5英寸的内径239。
在一些实施方式中，圆锥滚子轴承230在纵向方向(即，纵向轴线206的方向)上具有小于1.0英寸的长度241。在其他实施方式中，圆锥滚子轴承230具有小于0.9英寸的长度241。在又一些其他实施方式中，圆锥滚子轴承230具有小于0.8英寸的长度241。在另外的实施方式中，圆锥滚子轴承230具有小于0.7英寸的长度241。在又一些另外的实施方式中，圆锥滚子轴承230具有小于0.6英寸的长度241。在至少一个实施方式中，圆锥滚子轴承230具有小于0.5英寸的长度241。
图3-2图示了根据本公开的线性致动器300的另一实施方式的侧视横截面图。线性致动器300包括马达302，该马达302构造成通过梯形螺杆322使轴304沿着纵向轴线306移动。虽然本文中所描述的线性致动器的实施方式可以关于圆锥滚子轴承来描述，但是在其他实施方式中，线性致动器300包括定位在轴304与壳体308之间的角接触滚子轴承330。角接触滚子轴承330包括弯曲的内座圈331、弯曲的外座圈335以及定位在内座圈331与外座圈335之间的多个滚珠333。
在一些实施方式中，角接触滚子轴承330可以定位在梯形螺杆322的至少一部分与壳体308之间。例如，角接触滚子轴承330可以定位在梯形螺杆322的肩部与壳体308之间。轴304上的径向力328和/或轴向力可以传递至梯形螺杆322并且传递至角接触滚子轴承330。
图4-1和图4-2图示了线性致动器200从图4-1中的缩回状态移动至图4-2中的伸出状态的示例以及可以施加至轴204的相关联的径向力228。图4-1是处于竖向位置且处于缩回状态的线性致动器200的侧视横截面图。在锻炼系统的框架的运动期间，线性致动器200可以施加轴向伸出力以使框架的一部分从基部的一部分移动得更远。在缩回状态下，线性致动器200可以使轴204的一部分处于梯形螺杆222的第一端部238处或附近。轴204的纵向轴线206可以大致在重力的方向上。例如，轴204可以是大致竖向的。在此类实施方式中，框架或锻炼系统的使用者的重量可以仅在纵向轴线206的方向上施加轴向力。
图4-2图示了处于伸出状态的线性致动器200的示例。在基部与框架之间具有铰接连接的锻炼系统中(比如关于图2所描述的)，线性致动器200可以在使线性致动器200在缩回状态与伸出状态之间移动时改变取向。例如，当框架相对于基部的坡度增加时，铰接的框架和基部的弧形运动可以导致线性致动器200在取向上倾斜。换句话说，线性致动器200的纵向轴线206可以相对于重力方向形成非零角度。在一些实施方式中，纵向轴线206可以以相对于重力的2°、5°、10°、15°、20°、25°或30°的取向定向。随着相对于重力的取向的增加，径向力228施加至轴204的可能性增加。
框架可以连接至轴204的连接点240并且/或者向轴204的连接点240施加力。向下的力242可以具有径向力228分量。向下的力242可以包括框架的重力重量、使用者的重力重量、由使用者(例如，在跑步机上跑步期间)施加的任何向下的力或其组合。在一些实施方式中，由于使用者(例如，在跑步机上跑步期间)施加至框架的侧向力，轴204可能经受另一径向力228。此外，在比如图4-2中所图示的伸出状态下，轴204可以用作伸出杠杆，从而使通过径向力228施加至梯形螺杆222的扭矩的量增加。
常规的线性致动器仅在轴向应用中使用。圆锥滚子轴承230可以允许轴204和梯形螺杆222接收非轴向力(即，径向力228)而不会使线性致动器的推力轴承或其他部件过早磨损。径向力228可以向轴204和/或梯形螺杆222施加扭矩，该扭矩由圆锥滚子轴承230接收并且由圆锥滚子轴承230抵消，从而允许将根据本公开的线性致动器200的一个或更多个实施方式用于非轴向应用中，而无需重新设计周围系统、无需使用不同类型的致动器或不会使装置过早失效，从而降低了线性致动器和/或使用线性致动器的系统的设计、制造、维护和维修成本。
根据本公开的线性致动器的至少一个实施方式可以通过使由线性致动器从伸出状态移动至缩回状态而产生的力减小而进一步增加线性致动器的耐久性。例如，线性致动器可以产生比缩回力大的伸出力，以限制由线性致动器产生的热，从而限制在高占空比(比如大于50％的占空比)期间对线性致动器的热损坏。
在一些实施方式中，线性致动器可以产生伸出力以使框架和/或使用者的质量抵抗重力移动。线性致动器可以产生较小的缩回力，并且利用重力使框架和/或使用者的质量高效地移动。例如，线性致动器可以产生由图5的上部曲线表示的伸出力244。当使线性致动器沿伸出方向246朝向伸出状态移动时，可以产生伸出力244。线性致动器可以产生由图5的下部曲线表示的缩回力248。当使线性致动器沿缩回方向250朝向缩回状态移动时，可以产生缩回力248。
线性致动器可以具有由伸出力244与缩回力248之间的比率限定的效率比。在一些实施方式中，效率比在整个运动范围内可以大致恒定。在其他实施方式中，效率比可以在缩回状态与伸出状态之间的运动期间改变。
在一些实施方式中，效率比可以大于1.0。在其他实施方式中，效率比可以在1.0与10.0之间。例如，伸出力244可以是1000磅的力，而缩回力248可以是至少100磅的力。在又一些其他实施方式中，效率比可以在1.0与5.0之间。例如，伸出力244可以是1000磅的力，而缩回力248可以是至少200磅的力。在另外的实施方式中，效率比可以在1.0与4.0之间。例如，伸出力244可以是1000磅的力，而缩回力248可以是至少250磅的力。在又一些另外的实施方式中，效率比可以在1.0与2.0之间。例如，伸出力244可以是1000磅的力，而缩回力248可以是至少500磅的力。
应当理解的是，线性致动器可以在与本文中所描述的方向相反的方向上定向，其中，线性致动器构造成在朝向缩回状态移动时使框架和/或使用者的质量抵抗重力移动。换句话说，线性致动器可以向上“拉动”框架和/或使用者，而不是向上“推动”框架和/或使用者。在此类实施方式中，由于缩回力可能大于伸出力，因此效率比可能反转。
图6是图示了支承线性致动器的方法352的流程图。方法352包括在354处通过轴接收径向力，并且在356处将径向力传递至支承轴的梯形螺杆。然后在358处，传递至梯形螺杆的力可以向圆锥滚子轴承施加扭矩。圆锥滚子轴承可以支承梯形螺杆抵抗径向力，同时允许梯形螺杆相对于轴旋转。方法352可以可选地包括在360处继续使梯形螺杆旋转，以通过伸出力使轴朝向伸出状态移动。此外，方法352可以可选地包括在362处通过缩回力使轴朝向缩回状态移动，其中，缩回力相比于伸出力具有不同的大小。
在一些实施方式中，缩回力的大小可以小于伸出力的大小。例如，缩回力的大小可以小于伸出力的大小的一半。在其他示例中，缩回力的大小可以小于伸出力的大小的三分之一。在又一些其他示例中，缩回力的大小可以小于伸出力的大小的四分之一。在另外的示例中，缩回力的大小可以小于缩回力的伸出的五分之一。
工业适用性
总体上，本发明涉及在横向加载期间或在向轴施加径向力期间对线性致动器的轴进行支承。常规的线性致动器包括推力轴承或衬套，以支承轴和/或支承对轴进行支承的梯形螺杆。在包括施加至轴的侧向力或径向力的应用中，通常不使用线性致动器，因为在这种应用中的线性致动器的典型操作寿命会变短。
在根据本公开的一些实施方式中，线性致动器可以包括圆锥滚子轴承，该圆锥滚子轴承支承轴和/或支承对轴进行支承的梯形螺杆。线性致动器可以包括构造成使轴沿着轴的纵向轴线轴向地移动的马达。该马达可以通过壳体和套筒连接至轴。壳体可以容纳一个或更多个齿轮、带、线缆或其他扭矩传递装置，以将扭矩从马达传递至套筒中的梯形螺杆。梯形螺杆可以与轴上的互补表面特征相互作用，使得随着梯形螺杆的旋转，轴沿纵向轴线的方向移动。
梯形螺杆可以由定位在壳体内并且由马达驱动的齿轮的联动装置驱动。在其他实施方式中，从马达至梯形螺杆的联动装置可以包括用于将扭矩从马达传递至梯形螺杆的带、链、凸轮、杠杆或其他机构。
在一些实施方式中，轴可能经受在相对于纵向轴线(即，垂直于纵向轴线)的径向方向上施加的力。通过径向力施加至轴的扭矩可以被传递至线性致动器的梯形螺杆或其他部件，并且传递至梯形螺杆或其他部件与壳体和/或齿轮之间的连接件。例如，径向力可能通过在跑步机上跑步的使用者对锻炼系统的侧向冲击引起。在其他示例中，当锻炼系统以坡度或倾斜度定位时，该力可能通过由使用者和/或搁置在线性致动器上的框架的重量施加的向下的力引起。
线性致动器包括定位在轴与壳体之间的圆锥滚子轴承。在一些实施方式中，圆锥滚子轴承可以定位在梯形螺杆的至少一部分与壳体之间。例如，圆锥滚子轴承可以定位在梯形螺杆的肩部与壳体之间。
轴上的径向力和/或轴向力可以传递至梯形螺杆且传递至圆锥滚子轴承。在一些实施方式中，圆锥滚子轴承可以在纵向轴线与圆锥滚子轴承的轴承轴线之间具有轴承角。轴承角可以在以下范围内：该范围具有包括5°、10°、15°、20°、25°、30°、35°、40°、45°或其间的任何值中的任一者的上限值、下限值或者上限值和下限值。在一些示例中，轴承角可以大于5°。在其他示例中，轴承角可以小于45°。在又一些其他示例中，轴承角可以在5°与45°之间。在另外的示例中，轴承角可以在5°与30°之间。在又一些另外的示例中，轴承角可以是大约10°。圆锥滚子轴承的轴承角可以通过定向成接收相对于梯形螺杆上的轴向力更大的径向力或接收相对于径向力更大的轴向力来影响线性致动器的操作寿命。
在一些实施方式中，线性致动器可以在伸出方向和缩回方向(即，“推动”和“拉动”方向)上产生不同的力。例如，线性致动器可以构造成在伸出方向上比在缩回方向上施加更大的力。在其他示例中，线性致动器可以构造成在缩回方向上比在伸出方向上施加更大的力。在一些应用中，线性致动器可以使一个或更多个物体在一个方向上抵抗重力而升起，而重力可以辅助物体在相反方向上的运动。线性致动器可以在通过以较低的力产生和/或以更有效的模式操作而移动“辅助方向”时减少或限制产生的热和消耗的能量。因此，线性致动器可以具有效率比，该效率比限定为线性致动器在第一方向上相对于在第二方向上所产生的力的相对量。
在一些实施方式中，效率比可以大于1.0。在其他实施方式中，效率比可以在1.0与10.0之间。例如，伸出力可以是1000磅的力，而缩回力可以是至少100磅的力。在又一些其他实施方式中，效率比可以在1.0与5.0之间。例如，伸出力可以是1000磅的力，而缩回力可以是至少200磅的力。在另外的实施方式中，效率比可以在1.0与4.0之间。例如，伸出力可以是1000磅的力，而缩回力可以是至少250磅的力。在又一些另外的实施方式中，效率比可以在1.0与2.0之间。例如，伸出力可以是1000磅的力，而缩回力可以是至少500磅的力。
与常规的线性致动器相比，通过圆锥滚子轴承减小摩擦并且提高效率以减少热产生可以允许线性致动器具有增加的占空比。例如，根据本公开的线性致动器可以具有至少50％、至少75％、至少85％、至少95％的占空比或连续的占空比。在至少一个示例中，根据本公开的线性致动器可以具有在20分钟的持续时间内至少70％的占空比。
在一些实施方式中，根据本公开的线性致动器可以用于各种锻炼系统中。例如，线性致动器可以用于对跑步机、椭圆机、健身自行车、划船机、踏步机或可以包括在锻炼系统中的其他锻炼机器的坡度或倾斜度进行调节。线性致动器可以由使用者通过与线性致动器通信的计算装置或其他接口来手动地控制(例如，使用者可以自己选择坡度或倾斜度)，或者使用者可以在与线性致动器通信的计算装置中选择锻炼例程。
在一些实施方式中，计算装置可以与具有特定于所选用户的锻炼例程的用户简档进行通信或访问这些用户简档。可以与本文中所描述的原理兼容的用户简档数据库的示例包括如上所述的iFit程序。在一些示例中，可以通过用户简档访问的用户信息包括使用者的年龄、性别、身体成分、身高、体重、健康状况、可能有助于确定用于使用者的适当的锻炼例程的其他类型的信息或其组合。此类用户简档信息能够通过iFit程序应用于计算装置。
