Description

一种将往复运动转换成连续转动的装置和方法及应用 技术领域
本发明涉及机械装备技术领域，更具体地说是涉及一种将往复运动转换成连续转动的装置和方法及应用。
 背景技术
固定翼飞机的效率较高，但在起飞和降落过程中，均需要较长的跑道，且不能悬停，机动性差，安全性也不高。直升机能垂直升降，但效率较低、结构复杂、操作难度大且安全性不高。
因此，提供一种设计合理、结构简单、便于操作、安全可靠、效率较高能为飞行器提供持续升力的将往复运动转换成连续转动的装置是本领域技术人员亟需解决的问题。
 技术解决方案
本发明旨在至少在一定程度上解决现有技术中的上述技术问题之一，为此，本发明的一个目的在于提供了一种设计合理、结构简单、便于操作、安全可靠、效率较高能为飞行器提供持续升力的将往复运动转换成连续转动的装置。
本发明的第二个目的在于提供了一种利用该装置将往复运动转换成连续转动的方法。
本发明的第三个目的在于提供了一种具有所述将往复运动转换成连续转动的装置的飞行器。
本发明的另一个目的在于提供了一种具有所述的将往复运动转换成连续转动的装置的水中机械。
本发明的另一个目的在于提供了一种具有所述的将往复运动转换成连续转动的装置的健身器材。
为了实现上述第一个目的，本发明采用如下技术方案：
一种将往复运动转换成连续转动的装置，包括：
中心轴，所述中心轴上设有与其转动连接的轴承；
转动盘，所述转动盘安装在所述轴承的圆周侧壁上，且所述转动盘与所述轴承同心布置；所述转动盘的圆周面上设有翼片，且所述翼片的一端安装在所述转动盘的圆周面上，翼片的展向与转动盘的径向同向；所述翼片的上翼面呈弧形且向上凸出，所述翼片的后缘比前缘尖锐；所述翼片有多个，多个所述翼片均匀布置在所述转动盘的周围，且多个所述翼片的前缘方向一致；所述翼片安装在所述转动盘上的安装角在－2度至4度之间。安装角即为翼片弦线与转动盘转动平面的夹角；翼片的前缘高于翼片的后缘时安装角为正，翼片的前缘低于翼片的后缘时安装角为负。
经由上述的技术方案可知，与现有技术方案相比，本发明公开提供了一种将往复运动转换成连续转动的装置，通过利用该装置中翼片的翼型结构及安装角的限定，能够实现该装置在沿中心轴轴向往复直线运动的过程中，保持翼片的转动方向不变，即始终保持翼片前缘在前，翼片后缘在后的转动方向进行转动。如果安装角的绝对值较大时，为方便起动该装置，可预先拨动翼片朝前缘方向转动。本发明的一种将往复运动转换成连续转动的装置，不仅设计合理，结构简单，而且操作简单，易于控制，效率较高，能够用作机械传动机构，将往复直线运动转变成圆周转动，也能够为飞行器提供持续的升力或为水中机械提供持续的转动，具有良好的应用前景。
进一步的，所述翼片采用的型号为NACA2412翼型或NACA0012翼型中的一种。
如果将上述装置的中心轴竖直放置，装置的往复运动即为上下运动，如使向下运动的速度比向上运动的速度快的话，采用上述技术方案产生的有益效果是，能够使该装置翼片在连续转动的过程中升阻比较大，转动过程中能够持续产生较大的升力，并且使得该装置中的翼片在转动过程中，能够减小翼片的迎风面积从而降低压差阻力，防止翼片上的气流在流经翼片上翼面时出现过早分离，造成升力损失，从而使该翼片具有良好的气动特性。
进一步的，所述翼片有三个，三个翼片互成120度布置，且三个所述翼片的前缘方向一致。
采用上述技术方案产生的有益效果是，能够使该装置的结构更加合理，三个翼片的设置使得该装置在不增加制造成本的基础上，能够在连续转动的过程中持续产生较大的升力。
进一步的，所述转动盘为两个，与两个所述转动盘对应布置的所述轴承有两个，两个所述转动盘通过轴承与所述中心轴相连，两个所述转动盘平行布置，且分别设于两个所述转动盘上的所述翼片的前缘方向相反。
采用上述技术方案产生的有益效果是，双层旋翼的设计不仅使得该装置的结构更加紧凑，还使得该装置在双层翼片的转动作用下能够产生更大的升力，同时，双层翼片的前缘方向相反的设置使得翼片在转动过程中能够抵消由于翼片转动带动轴承与中心轴的摩擦而作用于中心轴上的扭力。
本发明的第二方面还提出了一种利用上述装置将往复运动转换成连续转动的方法，其步骤如下：
（1）将该装置置于气体中或液体中，采用动力驱动该装置中心轴的一端使该装置沿中心轴的轴向朝向一个方向做直线运动，此时，由于气体或液体对翼片的作用使翼片运动，在该装置上的翼片带动转动盘进行转动，且转动方向为翼片前缘向前，翼片后缘在后的方向；
（2）驱动该装置的中心轴的另一端使该装置朝向与（1）中的相反方向做直线运动，此时，该装置上的翼片带动转动盘继续进行转动，且转动方向为翼片前缘向前，翼片后缘在后的方向。
进一步的，在步骤（1）和（2）中，该装置翼片的转动方向相同，当翼片的上、下两个表面的凸度不对称时或者直线运动的往复速度不相同时或者翼片的安装角大于零时，该装置能产生恒定方向的升力。
根据本发明的将往复运动转换成连续转动的方法，通过利用根据本发明第一方面所述的将往复运动转换成连续转动的装置，能够实现使装置产生持续的升力、结构简单且效率较高，运用此结构的方法使装置能够将往复运动转换成翼片的连续转动，从而产生恒定方向的升力或推力。
本发明的第三方面还提供了一种飞行器，所述飞行器包括根据本发明的第一方面所述的将往复运动转换成连续转动的装置。
根据本发明的飞行器通过利用根据本发明的第一方面所述的将往复运动转换成连续转动的装置，能够实现该飞行器在起降和巡航过程中产生持续向上的升力，并在飞行器机身两侧均安装该装置或在飞行器机身的上方安装一个或多个该装置，为飞行器在空中平稳飞行提供持续的基本稳定的升力，从而有效节省了发动机的能量消耗，使得飞行器的结构更加简单、操作方便、易于控制，降低了飞行器的运行成本。
本发明的第四方面还提供了一种水中机械，所述水中机械包括根据本发明的第一方面所述的将往复运动转换成连续转动的装置。
根据本发明的水中机械通过利用根据本发明的第一方面所述的将往复运动转换成连续转动的装置，能够实现水中机械在行驶过程中产生向上的举力或用来发电。
本发明的第五方面还提供了一种机械传动机构。
根据本发明的机械传动机构通过利用根据本发明的第一方面所述的将往复运动转换成连续转动的装置，应用于机械传动机构中，用水或油作为介质，翼片在密闭容器中的水中或油中运动，作用是将往复直线运动的输入动力转换为圆周转动的输出动力。比曲轴连杆机构更简单高效。

 本发明的最佳实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
本发明公开了一种将往复运动转换成连续转动的装置，包括：
中心轴1，中心轴1上设有与其转动连接的轴承2；
转动盘3，转动盘3固定连接在轴承2的圆周侧壁上，且转动盘3与轴承2同心布置；转动盘3的圆周侧壁上设有翼片4，且翼片4的一端设于转动盘3的圆周面上，并与转动盘3固定连接，翼片4为上翼面41呈上凸弧形的翼型，且翼片4的前缘厚实，后缘尖锐。翼片4安装在转动盘3上的安装角在－2度至4度之间。安装角即为翼片4的弦线与转动盘3转动平面的夹角；翼片4的前缘高于翼片4的后缘时安装角为正，翼片4的前缘低于翼片4的后缘时安装角为负。
如图1所示，根据本发明的一个可选实施例，翼片4有三个，三个翼片4互成120度布置，且三个翼片4的前缘方向一致；具体地，翼片4采用的型号为NACA2412翼型，从而不仅能够使该装置的结构更加合理，而且使得该装置在不增加生产成本的基础上，保证翼片在连续转动的过程中持续产生较大的升力。
如图3所示，根据本发明的一个可选实施例，转动盘3为两个，与两个转动盘3对应布置的轴承2有两个，两个轴承2均匀布置在中心轴1上，两个转动盘3平行布置，且分别设于两个转动盘3上的翼片4的前缘方向相反，双层旋翼的设计不仅使得该装置的结构更加紧凑，还使得该装置在双层翼片的转动作用下能够受到更大的升力，同时，双层翼片中前缘方向相反的设置使得翼片在转动过程中能够抵消由于翼片转动而作用于中心轴上的扭力。
本发明中的一种将往复运动转换成连续转动的装置，通过利用该装置中翼片的翼型结构，及安装角的限定，能够实现该装置在往复直线运动的过程中，始终保持翼片的转动方向不变，即始终保持翼片前缘在前，翼片后缘在后的转动方向进行转动，从而为该装置持续提供恒定方向的升力。如果安装角的绝对值大于1度时，为方便起动该装置，可预先拨动翼片朝前缘方向转动。本发明的一种将往复运动转换成连续转动的装置，不仅设计合理，结构简单，而且操作简单，易于控制，效率较高，能够为飞行器提供持续的升力或为船舶航行提供持续的推力，具有良好的应用前景。
下面描述本发明的一种如上述实施例中将往复运动转换成连续转动的方法，其步骤为：
（1）拉动该装置中中心轴的一端使该装置朝向一个方向做直线运动，此时，在装置处于的环境中的介质（空气或水）的作用下翼片运动，该装置上的翼片带动转动盘进行转动，且转动方向为翼片前缘向前，翼片后缘在后的方向；
（2）拉动（1）中该装置的中心轴的另一端使该装置朝向与（1）中的相反方向做直线运动，此时，该装置上的翼片带动转动盘继续按照（1）中的方向转动，即转动方向为翼片前缘向前，翼片后缘在后的方向。
根据本发明的一个可选实施例，在步骤（1）和（2）中，翼片的上表面凸度大于翼片下表面的凸度，直线运动的往复速度不相同，向下直线运动是采用动力驱动的，速度较快，向上直线运动是由于翼片的高速转动产生的升力作用的结果，上行速度较慢，该装置翼片的转动方向相同，这样该装置产生向上的升力。
本发明中的一种将往复运动转换成连续转动的方法，通过利用根据本发明上述实施例中的将往复运动转换成连续转动的装置，能够实现结构上使装置产生持续的升力、结构简单且效率较高，运用此结构的方法使装置能够将往复运动转换成翼片的连续转动，还能产生恒定方向的升力或推力。
下面描述本发明的飞行器，所述飞行器包括根据本发明上述实施例的将往复运动转换为连续转动的装置。
本实施例中的飞行器机身两侧均安装有上述实施例中所述的将往复运动转换为连续转动的装置，且上述装置对称设置在机身两侧，且使上述装置连接有动力源，在飞行器起飞的过程中，通过上述装置沿飞行器机身向外侧做类似半转机构运动，从而使得上述装置沿飞行器机身做公转运动的同时进行自转，自转过程中翼片快速旋转，从而使飞行器受到持续向上的升力，带动飞行器离地起飞；在飞行器升至空中进行平飞的过程中，在飞行器机身两侧产生向前和向后的气流，从而带动上述装置的翼片进行高速旋转，进而为飞行器产生持续向上的升力；在飞行器降落的过程中，上述装置受到向上的气流的作用，从而带动上述装置的翼片旋转，进而持续为飞行器提供向上的升力，保持飞行器能够平稳降落。
根据本发明实施例的飞行器通过利用根据本发明第一方面实施例所述的将往复运动转换成连续转动的装置，能够实现该飞行器在起飞、平飞和降落的过程中产生持续向上的升力，并在飞行器机身两侧均安装该装置，为飞行器在空中平稳飞行提供持续稳定的升力，从而有效节省了发动机的能量消耗，使得飞行器的结构更加简单、操作方便、易于控制，降低了飞行器的运行成本。
下面描述本发明的水中机械，所述水中机械为船舶，该船舶包括根据本发明上述实施例的将往复运动转换为连续转动的装置。
本实施例中的船舶机体两侧均安装有上述实施例中所述的将往复运动转换为连续转动的装置，且上述装置对称设置在机身两侧，且使上述装置连接有动力源，在船舶航行的过程中，通过上述装置沿船舶机体向外侧倾斜呈一定角度做类似半转机构运动，从而使得上述装置沿船舶机体做公转运动的同时进行自转，自转过程中翼片快速旋转，从而使船舶受到持续斜向前上方的推力，带动船舶快速行驶，且能够保持船舶在快速航行过程中的机身平稳。
根据本发明实施例的船舶通过利用根据本发明的第一方面实施例所述的将往复运动转换成连续转动的装置，能够实现船舶在行驶过程中产生向上和向前的推力，并在船舶机体两侧均安装该装置，为船舶保持平稳运行提供持续稳定的推力，从而有效节省了发动机的能量消耗，使得船舶的结构更加简单、操作方便、易于控制，降低了船舶的运行成本。
