参阅图1及图2，实用新型一实施例中的往复传动组件10，至少能够消除偏摆角，消除偏向力摩擦做功，且往复传动组件10的结构简单，适用性好。具
体地，往复传动组件10包括转动套100、往复轴200及限位体300，转动套100绕自身轴线可转动；往复轴200穿设于转动套100内；限位体300定位于往复轴200的外壁与转动套100的内壁两者中的一者上，另一者上设有往复导轨，所述往复导轨的轨迹为绕转动套100轴线的闭合型曲线，且所述往复导轨的波峰与波谷沿转动套100的轴线间隔设置，限位体300与往复导轨导向配合，并能够沿着往复导轨的轨迹移动，以使往复轴200相对于转动套100沿着转动套100轴线方向往复移动。
在本实施例中，限位体300定位于转动套100的内壁上，往复导轨设置于往复轴200的外壁上。
一并参阅图3及图4，由于限位体300与往复导轨一者设置于转动套100的内壁上，另一者设置于往复轴200的外壁上，且由于往复导轨为绕传动轴轴线的闭合型曲线导轨，往复导轨的波峰与波谷沿转动套100的轴线间隔设置。往复轴200穿设于转动套100内，以使限位体300与往复导轨导向配合。进而当转动套100绕自身轴线转动时，使得限位体300在往复导轨的波峰与波谷之间移动。当限位体300定位在转动套100内壁上时，限位体300跟随转动套100转动，以通过限位体300与往复导轨的配合，使得往复轴200沿转动套100轴线往复移动的目的。上述往复传动组件10不存在偏摆角，也就不存在偏向力摩擦做功的问题；且结构简单，适用范围广，能够用于压缩机、泵体结构等需要往复移动的场合。
一实施例中，所述往复导轨的数量为至少两个，各个所述往复导轨沿着转动套100的轴线方向间隔设置，每一所述往复导轨均设置有至少一限位体300。在本实施例中，限位体300定位在转动套100上，则各个限位体300跟随转动套100同步转动。不同往复导轨上的限位体300相对于往复轴200可同步转动。
通过设置多个往复导轨，且每一往复导轨内均设置有至少一个限位体300配合传动，能够提高转动套100输出动力至往复轴200的功率，可以适用于大功率工作状态下。当然，在其他实施例中，往复导轨还可以为一个。
参阅图2至图4，一实施例中，往复导轨沿转动套100的周向的轨迹呈正弦曲线。当转动套100带动限位体300沿往复导轨的轨迹移动时，利用呈正弦曲线轨迹布置的往复导轨，保证限位体300在往复导轨上能够顺滑移动，保证往复轴200往复移动的平稳。
具体地，单个往复导轨沿转动套100的周向的轨迹包括至少两个完整且连续的正弦曲线周期，单个所述往复导轨上设有的限位体300的数量小于或等于所述往复导轨的正弦曲线周期数量，且单个往复导轨上的限位体300围绕转动套100的轴线均匀间隔设置。
例如，在本实施例中，往复导轨的轨迹包括两个正弦曲线，限位体300的数量也为两个，两个限位体300能够同时布置于往复导轨的两个正弦曲线的波谷位置或同时布置在两个正弦曲线的波峰位置，且此时的两个限位体300围绕转动套100的轴线均匀设置。通过均匀布置的限位体300与正弦曲线型的往复导轨的配合，能够进一步提高传动稳定性。
在其他实施例中，单个往复导轨绕转动套100的轴线的轨迹可以包括三个或其他数目个完整且连续的正弦曲线周期，对应的限位体300的数量可以为三个或其他数目个，且每一正弦曲线对应设置一限位体300，以保证往复轴200的稳定往复移动。
参阅图2及图3，一实施例中，往复导轨为往复槽400，往复槽400为绕转动套100轴线的闭合型曲线凹槽，限位体300穿设于往复槽400内并能够在往复槽400内移动。利用往复槽400实现对限位体300限位导向作用，保证限位
体300能够沿着往复槽400的轨迹稳定移动。
具体地，转动套100的内壁上开设有定位槽110；限位体300包括万向球，由于限位体300定位在转动套100上，则万向球的部分可滚动地设置于定位槽110内，另一部分穿设于往复槽400内。由于万向球可滚动，进而使得往复轴200相对于转动套100的往复移动是利用万向球的滚动摩擦实现，而非是往复轴200相对于转动套100的滑动摩擦，进一步保证传动效率。且通过设置定位槽110能够有效定位万向球在转动套100上的位置。
一实施例中，限位体300还包括限位座及多个滚珠，多个所述滚珠设置于所述限位座内，所述万向球部分穿设于所述限位座内并与所述滚珠抵接，所述万向球与所述滚珠均能够相对于所述限位座滚动，所述限位座设置于所述定位槽110内。当万向球在滚动时，利用多个滚珠实现万向球与限位座之间的滚动摩擦，进一步保证万向球滚动的稳定性，且避免了万向球与定位槽110内壁之间的直接接触。
在其他实施例中，限位座还可以省略，多个滚珠直接设置于定位槽110内，万向球穿设于定位槽110内并与滚珠抵接。
在其他实施例中，往复导轨还可以为往复凸起，往复凸起为绕转动套100轴线的闭合型曲线凸起，且曲线凸起的波峰与波谷沿转动套100的轴线间隔设置，限位体300上开设有凹槽，往复凸起穿设于凹槽内。只要能够保证限位体300沿着往复导轨的轨迹移动即可。
一实施例中，往复轴200的外壁直径与转动套100的内壁直径一致。例如往复轴200与转动套100之间可以过盈配合，避免往复轴200内壁与转动套100之间直接接触摩擦。在其他实施例中，往复轴200的外壁直径略大于转动套100的内壁直径，以保证往复轴200外壁与转动套100的内壁之间具有较小间隙。
一并参阅图5，在本实施例中，转动套100包括第一套部120及第二套部130，第二套部130穿设于第一套部120内，并限位于第一套部120上，定位槽110开设于第二套部130的内壁上，第一套部120能够带动第二套部130同步转动。由于第一套部120为转动动力传递部件，通过将定位槽110开设于第二套部130上，以便于保证第一套部120结构的完整性，进而保证转动传递的稳定性。
具体地，第一套部120的内壁上设置有限位凸起122，第二套部130的外壁上设置有配合凹槽132，限位凸起122能够穿设于配合凹槽132内，以保证第二套部130稳定地设置于第一套部120内。进一步地，限位凸起122的数量为至少两个，各个限位凸起122绕第一套部120的轴线均匀间隔设置，配合凹槽132的数量与限位凸起122的数量一致，每一限位凸起122对应穿设于一配合凹槽132内。
一实施例中，往复传动组件10还包括动力源；转动套100的一端设置有动力轴140，所述动力源连接于动力轴140，并通过动力轴140驱动转动套100转动。通过设置动力源便于将转动输出至转动套100，实现转动套100的转动。
在本实施例中，由于转动套100包括第一套部120及第二套部130，则第一套部120的一端设置有动力轴140；通过动力轴140与动力源，便于为第一套部120的转动提供动力。
具体地，第一套部120背向于动力轴140的一端开口，第二套部130及往复轴200由第一套部120的开口端穿设于第一套部120内。通过第一套部120上的开口端方便第二套部130及往复轴200设置于第一套部120内。
参阅图2至图4，一实施例中，往复传动组件10还包括输出轴500，输出轴500由转动套100背向于动力轴140的一侧连接于往复轴200。通过输出轴
500便于将往复轴200的往复移动通过输出轴500输出至其他部件。
一实施例中，往复传动组件10还包括壳体600，往复轴200及转动套100均设置于壳体600内。通过壳体600能够有效保护往复轴200与转动套100，保证往复轴200与转动套100之间传动的稳定性。
具体地，壳体600包括壳本体610及盖体620，壳本体610的一侧开口，往复轴200及转动套100由壳本体610的开口侧设置于壳本体610内，盖体620盖设于壳本体610上。
进一步地，壳体600的一侧壁上开设有输入孔630，相对的另一侧壁上开设有输出孔640，动力源通过输入孔630连接于转动套100的动力轴140，输出轴500穿设于输出孔640内。更进一步地，输入孔630与输出孔640分别开设于壳本体610及盖体620上。
一实施例中，往复传动组件10还包括平衡轴及平衡体，所述平衡轴穿设于所述转动套100内，并位于所述往复轴200的一侧，所述平衡轴的外壁与转动套100的内壁两者中的一者上定位有所述平衡体，另一者上设有与所述往复导轨间隔设置的平衡导轨，所述平衡导轨的轨迹为绕转动套100轴线的闭合型曲线，所述平衡体与所述平衡导轨导向配合，并能够沿着所述平衡导轨的轨迹移动，以使所述平衡轴与所述往复轴200相对或相背移动。当驱动转动套100转动时，平衡体沿着平衡导轨的轨迹移动，限位体300沿着往复导轨的轨迹移动，以使平衡轴与往复轴200沿转动套100的轴线方向相对或相背移动，进而使得平衡轴的加速度产生的力能够与往复轴200的加速度产生的力相互抵消，避免单独设置往复轴200而导致对转动套100产生轴向振动。通过平衡体与平衡轴的配合，能够避免往复轴200及转动套100的轴向振动，提高传动的稳定性。
在本实施例中，所述平衡体与所述限位体300的结构一致，所述平衡导轨
的结构与往复导轨的结构一致。
具体地，所述平衡导轨沿转动套100的周向的轨迹呈正弦曲线，所述平衡导轨的波峰与所述往复导轨的波谷相对，所述平衡导轨的波谷与所述往复导轨的波峰相对，所述平衡体与所述限位体300沿着所述转动套100的轴向相对设置。当限位体300在往复导轨上沿一个方向移动时，以便于使得平衡体500能够在平衡导轨上沿相反方向移动，进而实现往复轴200与平衡轴沿不同方向移动。
一实施例中，所述平衡导轨与所述往复导轨均设置于转动套100的内壁上。限位体300定位于往复轴200的内壁，平衡体定位于平衡轴的内壁上。使得限位体300与平衡体能够同步相对于转动套100相对或相背运动，进一步使得转动套100受到的限位体300与平衡体的力能够相互抵消。
在另一实施例中，所述平衡导轨还可以设置于平衡轴的外壁上，往复导轨设置于往复轴200的外壁上。限位体300与平衡体均定位于转动套100的内壁上，且沿着转动套100的轴线方向间隔设置。
如图6至图8，在本实施例中，限位体300定位于往复轴200的外壁，往复导轨设置于转动套100的内壁上。往复导轨跟随转动套100转动时，实现限位体300跟随往复轴200同步移动的目的。
在本实施例中，与上述实施例中记载的方案的区别在于：
一实施例中，往复导轨的数量为至少两个，各个所述往复导轨沿着转动套100的轴线方向间隔设置，在本实施例中，限位体300定位在往复轴200上，各个限位体300能够跟随往复轴200同步移动。不同往复导轨上的限位体300相对于转动套100可同向移动，能够提高转动套100输出动力至往复轴200的功率。
参阅图7至图9，在本实施例中，定位槽110开设于往复轴200的外壁上。通过定位槽110将限位体300定位于往复轴200上，以实现限位体300与往复轴200的同步移动。
具体地，往复轴200包括传动轴210及传动套220，传动套220套设于并限位于传动轴210上，定位槽110开设于传动套220的外壁上。由于传动轴210输出往复移动，进而通过在传动套220上开设定位槽110，能够保证传动轴210的结构完整，保证动力输出的稳定。
如图7所示，在本实施例中，转动套100的一端设置有动力轴140，动力源连接于所述动力轴140，并通过动力轴140驱动所述转动套100转动。
在本实施例中，转动套100包括第一拼接部150及第二拼接部160，第一拼接部150与第二拼接部160均为半圆柱形结构，第一拼接部150与第二拼接部160相对接以使往复轴200位于第一拼接部150与第二拼接部160之间。通过设置第一拼接部150与所述第二拼接部160拼接，便于设置往复轴200，且便于使得限位体300与往复导轨导向配合。具体地，便于使得限位体300穿设于往复槽400内。
具体地，动力轴140包括第一拼接轴142及第二拼接轴144，第一拼接部150与所述第二拼接部160相对接后，第一拼接轴142与第二拼接轴144对接形成动力轴140。
在其他实施例中，转动套100还可以为一体式结构。
如图2及图7所示，上述往复传动组件10，动力源驱动转动套100转动时，往复轴200沿着转动套100的轴线往复运动，并利用万向球实现往复轴200与转动套100之间的滚动摩擦，且利用均匀布置的至少两个万向球，使得往复轴200受到均匀的往复推力，不会受到偏向力的影响。往复轴200的往复过程只有
沿着转动套100的轴线方向的移动轨迹及推力，可实现双向做功的目的，提高传动效率。
一实施例中，动力机构包括上述任一实施例中往复传动组件10。例如动力机构可以为压缩机，压缩机的活塞可以连接于往复轴200。或者动力机构可以为柱塞泵，柱塞泵的柱塞连接于往复轴200。或者动力机构可以为电锤，电锤的缸体连接于往复轴200。在其他实施例中，动力机构还可以为其他需要往复动力的部件。

在本实用新型中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本实用新型中的具体含义。
在本实用新型中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
