Description

飞轮装置 技术领域
本发明是关于一种飞轮装置，尤其是一种于径向方向上具有不均等的重量配置的飞轮装置。
背景技术
请参照图1所示的一种现有技术的飞轮装置9，该飞轮装置9包含一轮盘91，该轮盘91中央开设一轴孔92，该轮盘92用以供结合一转动轴（图未绘示）。该飞轮装置9可以受该转动轴带动而旋转，其中，该轮盘91于该转动轴的径向方向上的重量分布均等，在该轮盘91转动时，将产生环绕该转动轴旋转的趋向，使得该飞轮装置9能够提供一扭力(torque)。
 技术问题
然而，受到制程公差影响，该轮盘91于该转动轴的径向方向上的重量分布无法完全均等，一旦该轮盘91的重心位置存在误差而偏离该轴孔92中心，在该轮盘91转动时将会产生偏心作用，致使该轮盘91形成不平衡的旋转，容易衍生轴向偏转(pitching)或震动(vibration)等情形，进而导致该飞轮装置9所能够提供的扭力随之下降。换言之，该飞轮装置9无法持续且稳定地提供扭力，造成该转动轴必须消耗更高的动力来维持该飞轮装置9的转速。
再者，该轮盘91为实心圆盘，因此该轮盘91的轴向截面将形成长方形，亦即，该轮盘91的轴向截面的有效截面积较大，使其具有较大的风阻系数，因而阻碍该轮盘91转动。据此，受到该轮盘91具有较大的风阻系数影响，该飞轮装置9的扭力输出可能会进一步降低。
有鉴于此，现有技术的飞轮装置9确实仍有加以改善的必要。
 技术解决方案
本发明提供一种飞轮装置，借助将一个轮盘沿一个圆周方向区分为八个区块，并且于各该区块设置一个凹槽，使各该区块具有不同的重量，以确保该轮盘能够平衡的旋转。
本发明的飞轮装置包含：一个轮盘，该轮盘中央设有一个轴接部，且该轮盘沿一个圆周方向区分为一个第一区块、一个第八区块、一个第三区块、一个第四区块、一个第九区块、一个第二区块、一个第七区块及一个第六区块，各该区块分别设有一个凹槽，且各该区块的凹槽的容积均不相等，使该第一区块、第二区块、第三区块、第四区块、第六区块、第七区块、第八区块及第九区块的重量比形成1：2：3：4：6：7：8：9。
如上所述的飞轮装置，其中，该第一区块、第八区块、第三区块、第四区块、第九区块、第二区块、第七区块及第六区块沿该圆周方向将该轮盘划分为放射状排列的八等分。
如上所述的飞轮装置，其中，该轮盘于该轴接部之径向方向上相对的任二区块的重量总和相等。
如上所述的飞轮装置，其中，该第一区块、第三区块、第九区块及第七区块与其各自二侧的区块的重量总和相等。
如上所述的飞轮装置，其中，该轮盘于该轴接部的一个轴向方向上具有呈相对的二个表面，各该区块的凹槽为盲槽，且各该区块的凹槽同时设置于该二个表面。
如上所述的飞轮装置，其中，该轮盘于该轴接部的径向方向上另区分为一个外环部及一个中央部，该中央部连接于该轴接部，该外环部环绕该中央部，且各该区块的凹槽设置于该中央部。
如上所述的飞轮装置，其中，另包含一个辅助转动模块，该辅助转动模块包含一个基座、一个调整件及一个磁性件，该调整件设置于该基座，该磁性件结合该调整件，该磁性件具有远离该基座的一个磁性面，该调整件用以使该磁性面与该基座的角度能够被略微调整，且各该区块的外周缘分别结合一个磁铁，各该磁铁具有远离该轮盘的一个磁性面，且各该磁铁的磁性面与该磁性件的磁性面具有相同的极性。
如上所述的飞轮装置，其中，当该磁性件未承受外力时，该磁性件的磁性面朝向该轮盘的外周缘，且当其中一个磁铁旋转接近该磁性件时，该磁性件将朝向与该磁铁相反的方向偏转，使得该磁性件的磁性面与该基座间形成一个夹角。
据由前述结构，本发明的飞轮装置可在各该区块设置容积均不相等的的凹槽，使各该区块具有不同的重量，即可使该轮盘的各个区块在旋转过程中的转动惯量不同，同时，通过适当排列各该区块可以使该轮盘受该转动轴带动而旋转时达到转动平衡的效果，使得该轮盘能够平衡的旋转而不会衍生轴向偏转或震动等情形，具有提升飞轮装置的扭力输出的功效。

 本发明的最佳实施方式
为让本发明的上述及其他目的、特征及优点能更明显易懂，下文特举本发明的较佳实施例，并配合所附图式，作详细说明如下：
请参照图2所示，是本发明飞轮装置第一实施例，该飞轮装置包含一个轮盘1，该轮盘1中央设有一个轴接部10，且该轮盘1可以沿一圆周方向（例如：顺时针方向或逆时针方向）区分为八个区块，分别为一个第一区块11、一个第八区块18、一个第三区块13、一个第四区块14、一个第九区块19、一个第二区块12、一个第七区块17及一个第六区块16。其中，该轴接部10可以为轴孔或单向轴承，用以结合一转动轴；或者，该轴接部10可以为轮轴，所述轮轴可以经由连轴器等传动装置接合于一转动轴，本发明并不以此为限。该轮盘1为圆形，且该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19将该轮盘1划分为放射状排列的八等分。该第一至第四区块11、12、13、14分别设有一凹槽111、121、131、141，同理，该第六至第九区块16、17、18、19亦分别设有一凹槽161、171、181、191，且各该区块的凹槽的容积均不相等，使得该第一、第二、第三、第四、第六、第七、第八及第九区块11、12、13、14、16、17、18、19的重量比形成1：2：3：4：6：7：8：9。
更详言之，该第一区块11的凹槽111的容积最大，该第二区块12的凹槽121的容积次之，接着依序为该第三、第四、第六、第七及第八区块13、14、16、17、18的凹槽131、141、161、171、181，该第九区块19的凹槽191的容积则最小。据此，该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19将形成具有不同重量的八个区块，且通过设计，使该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19的凹槽111、121、131、141、161、171、181、191的容积具有适当差值，即可使该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19的重量比形成1：2：3：4：6：7：8：9，为本领域技术人员所能理解实施者。
其中，请一并参照图3所示，是该第一实施例的飞轮装置沿图2的剖线I-I的剖视示意图，该轮盘1于该轴接部10的一轴向方向X上具有呈相对的二表面1a、1b，其中，各该区块的凹槽可以为盲槽，且各该区块的凹槽可以设置于该轮盘1的其中一表面；或者，各该区块的凹槽可以同时设置于该轮盘1的二表面1a、1b。举例而言，如图3所示，在本实施例中，该第一区块11的凹槽111呈对称状地设置于该轮盘1的二表面1a、1b；同样地，其它七个区块的凹槽亦呈对称状地设置于该轮盘1的二表面1a、1b。但是，各该区块的凹槽也可以为贯穿该二表面1a、1b的穿槽，本发明并不加以限制。
借助上述结构，本发明飞轮装置第一实施例实际使用时，该轴接部10可供结合一转动轴，该转动轴受一动力源（例如：马达）驱动，使该轮盘1可以受该转动轴带动而旋转。注意到，虽然该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19为具有不同重量的八个区块，然而该轮盘1于该轴接部10的径向方向上相对的任二区块的重量总和均相等。更详言之，已知该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19的重量比形成1：2：3：4：6：7：8：9，且该第一及第九区块11、19、该第二及第八区块12、18、该第三及第七区块13、17与该第四及第六区块14、16分别于该轴接部10的径向方向上相对，因此，若该第一及第九区块11、19的重量总和为W，则该第二及第八区块12、18、该第三及第七区块13、17与该第四及第六区块14、16的重量总和均为W。再者，请续参照图2所示，该第一区块11及其二侧的区块（第六及第八区块16、18）的重量总和为1.5W；该第三区块13及其二侧的区块（第八及第四区块18、14）的重量总和为1.5W；该第九区块19及其二侧的区块（第四及第二区块14、12）的重量总和为1.5W；且该第七区块17及其二侧的区块（第八二及第六区块12、16）的重量总和同样为1.5W。换言之，于该圆周方向上分别相差90°的第一区块11、第三区块13、第九区块19及第七区块17与其各自二侧的区块的重量总和均相等。
据此，该第一实施例借助使该轮盘1于该轴接部10的径向方向上相对的任二区块的重量总和相等，并且使于该圆周方向上分别相差90°的第一区块11、第三区块13、第九区块19及第七区块17与其各自二侧的区块的重量总和均相等，可以使该轮盘1受该转动轴带动而旋转时达到转动平衡的效果。其中，由于该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19具有不同重量，因此该轮盘1的各个区块在旋转过程中的转动惯量不同。以该轮盘1朝向该圆周方向旋转为例，该第九区块19的重量大于与其相邻的第二区块12的重量，使该第九区块19具有较高的转动惯量，当该第九区块19朝向该第二区块12的位置旋转时，该第九区块19能够迫使该第二区块12一并转动，使得该轮盘1能够稳定旋转。换言之，若将该第九区块19与第二区块12的转动过程以行进波函数分析时，该第九区块19的前进波大于该第二区块12地接收波，因此该第九区块19能够稳定朝向该第二区块12的位置旋转。类似的效应亦存在于该轮盘1的其它区块。
由此可知，本发明飞轮装置第一实施例利用该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19具有不同重量，使该轮盘1的各个区块在旋转过程中的转动惯量不同，并且通过适当排列各该区块可以使该轮盘1受该转动轴带动而旋转时达到转动平衡的效果。相较前述现有技术的飞轮装置9的轮盘91需要于径向方向上使重量形成均等分布，容易受到到制程公差影响使该轮盘91的重心位置存在误差，因而在该轮盘91旋转时衍生轴向偏转(pitching)或震动(vibration)等情形，本发明飞轮装置第一实施例使该轮盘1的各个区块具有不同重量，换言之，该轮盘1的各个区块的重量已预先存在差值，因此使该轮盘1不易受到制程公差影响。据此，本发明飞轮装置第一实施例的轮盘1在转动时不易产生偏心作用，该轮盘1能够平衡的旋转而不会衍生轴向偏转或震动等情形，使得该飞轮装置的能够持续且稳定地提供扭力，具有提升飞轮装置的扭力输出的功效。
再者，请续参照图3所示，本发明飞轮装置第一实施例借助于该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19亦分别设置一凹槽111、121、131、141、161、171、181、191，使该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19形成具有不同重量的八个区块。于该轮盘1的各个区块开设凹槽将可缩减该轮盘1的轴向截面的有效截面积，换言之，相较现有技术飞轮装置9的轮盘91的轴向截面形成长方形，本发明飞轮装置第一实施例利用于该轮盘1设置凹槽，能够缩减该轮盘1的有效截面积，以降低该轮盘1的风阻系数，具有近一步提升飞轮装置的扭力输出的功效。
为了凸显本发明飞轮装置第一实施例相较现有技术飞轮装置9确实具有较高的扭力输出，请一并参照图1及2所示，以旋转半径r为180mm且总重量为30kg的一轮盘1进行测试，并且采用旋转半径r’为180mm且总重量同样为30kg的现有技术飞轮装置9的轮盘91作为对照。以一马达作为动力源驱动该轮盘1旋转，该马达采用东元电机公司框号132M/额定电压220V/马力10HP/输出功率7.5kW的产品，该马达需消耗1.18kW的功率来带动该轮盘1以1800rpm的转速旋转；相对地，该马达需消耗1.4kW的功率才能带动现有技术的飞轮装置9的轮盘91以1800rpm的转速旋转。由此可知，在旋转半径r、r’及总重量相等的条件下，本发明飞轮装置第一实施例的轮盘1在旋转过程中所消耗的能量明显较低，足以显示该轮盘1相较现有技术的飞轮装置9的轮盘91能够较为稳定地旋转，因此本发明飞轮装置第一实施例能够持续且稳定地提供扭力，确实具有提升飞轮装置的扭力输出的功效。
根据上述第一实施例可知该轮盘1沿该圆周方向区分为八个区块，分别为一个第一区块11、一个第八区块18、一个第三区块13、一个第四区块14、一个第九区块19、一个第二区块12、一个第七区块17及一个第六区块16，该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19的重量比形成1：2：3：4：6：7：8：9。然而，该轮盘1为圆形，因此本发明所属领域中具有通常知识者根据该第一实施例可知，该轮盘1亦可沿该圆周方向区分为八个区块，分别为一个第一区块11、一个第六区块16、一个第七区块17、一个第二区块12、一个第九区块19、一个第四区块14、一个第三区块13及一个第八区块18，所述形式的轮盘1同样属于该第一实施例的范畴。
请参照图4所示，是本发明飞轮装置第二实施例，与前述第一实施例相异之处在于：该轮盘1于该轴接部10的径向方向上另区分为一外环部1c及一中央部1d，该中央部1d连接于该轴接部10，该外环部1c环绕该中央部1d，且第一至第四区块11、12、13、14与第六至第九区块16、17、18、19的凹槽111、121、131、141、161、171、181、191设置于该中央部1d。借此，该第一至第四区块11、12、13、14与第六至第九区块16、17、18、19于该外环部1c不会开设任何凹槽，使得该轮盘1的外围（邻近该外环部1c）的重量较重，且该轮盘1的中央（邻近该中央部1d）的重量较轻，能够进一步提升该轮盘1的旋转稳定性。
请参照图5所示，是本发明飞轮装置第三实施例，在本实施例中，该飞轮装置另包含一辅助转动模块2，该辅助转动模块2包含一个基座21、一个调整件22及一个磁性件23，该调整件22设置于该基座21，该磁性件23结合该调整件22，该磁性件23具有远离该基座21 一磁性面231。此外，该轮盘1的第一至第四区块11、12、13、14与第六至第九区块16、17、18、19的外周缘分别结合一磁铁3，各该磁铁3具有远离该轮盘1的一磁性面31，且各该磁铁3的磁性面31与该磁性件23的磁性面231具有相同的极性（例如：同为N极）。该调整件22可以为枢轴、滑座或弹簧等调整构造，用以使该磁性面231与该基座21的角度能够被略微调整。其中，当该磁性件23未承受外力时，该磁性件23的磁性面231较佳朝向该轮盘1的外周缘。
请参照图6所示，该第三实施例实际使用时，该轮盘1仍然受该转动轴带动而旋转，该辅助转动模块2用以辅助该轮盘1旋转。更详言之，以该轮盘1的第八区块18朝向该辅助转动模块2的位置旋转为例，请参照图7所示，该当该第八区块18旋转接近该磁性件23时，该第八区块18的外周缘所结合的磁铁3与该磁性件23之间将产生一斥力，由于该磁性件23结合于该调整件22，因此该磁性件23受到该斥力影响将略微朝向与该磁铁3相反的方向偏转，使得该磁性件23的磁性面231与该基座21间形成一夹角θ。此时，该磁铁3的磁性面31与该磁性件23的磁性面231的接触面积将会缩小，因此该斥力不会对该轮盘1的转动造成阻碍。
接着，请参照图8所示，当该第八区块18持续旋转至该辅助转动模块2的位置时，该磁铁3的磁性面31与该磁性件23的磁性面231的接触面积将会变大，且该磁性件23的磁性面231与该基座21间形成一夹角θ，因此该磁铁3与该磁性件23之间所产生的斥力能够辅助将该第八区块18沿着其旋转方向推动，以辅助该第八区块18继续朝向远离该辅助转动模块2的方向旋转。最后，请参照图9所示，当该第八区块18持续旋转而远离该辅助转动模块2后，由于该磁性件23不再承受任何外力，故该磁性件23的磁性面231将恢复朝向该轮盘1的外周缘。本发明飞轮装置第三实施例借助增设该辅助转动模块2，能够辅助该轮盘1旋转，确保该轮盘1能够稳定地旋转。
综上所述，本发明各实施例的飞轮装置借助将一轮盘1沿一圆周方向区分为八个区块，并且使各该区块具有不同的重量，即可使该轮盘1的各个区块在旋转过程中的转动惯量不同，同时，通过适当排列各该区块可以使该轮盘1受该转动轴带动而旋转时达到转动平衡的效果，使得该轮盘1能够平衡的旋转而不会衍生轴向偏转或震动等情形，确实具有提升飞轮装置的扭力输出的功效。
另一方面，本发明各实施例的飞轮装置于该轮盘1的各个区块分别设置一凹槽，使各该区块形成具有不同的重量。于该轮盘1之各个区块开设凹槽将可缩减该轮盘1的轴向截面的有效截面积，以降低该轮盘1的风阻系数，确实具有近一步提升飞轮装置的扭力输出的功效。
虽然本发明已利用上述较佳实施例揭示，然其并非用以限定本发明，任何熟习此技艺者在不脱离本发明的精神和范围之内，相对上述实施例进行各种更动与修改仍属本发明所保护的技术范畴，因此本发明的保护范围当视申请专利范围所界定的为准。
