Description

动力装置及其组装方法 技术领域
本发明涉及一动力装置，特别涉及一动力装置及其组装方法。
背景技术
发动机是工农业生产中最常见的动力装置之一，发动机在以自身动力运转之前，必须要借助外力带动才能实现旋转，而起动电机正是扮演着这个角色。起动电机将蓄电池中的电能转变为机械能，进而带动发动机以一预定的转速运转，以顺利地启动发动机。起动电机操作方便、起动迅速、可以重复起动，并且可以远距离控制，因此被广泛地应用于中小功率的发动机。
现有的动力装置100P包括一发动机10P、一起动电机20P以及一飞轮壳30P，其中所述发动机10P和所述起动电机20P分别被安装于所述飞轮壳30P，并使得所述起动电机20P被保持于所述发动机10P的一侧，且所述发动机10P被可驱动以转动地连接于所述起动电机20P，所述起动电机20P能够带动所述发动机10P运转。
具体来说，所述发动机10P包括一发动机主体11P和一发动机缸体12P，其中所述发动机主体11P被设置于所述发动机缸体12P，其中所述发动机缸体12P具有多个装配孔121，其中所述起动电机20P包括一电机主体21P和一安装部22P，所述安装部22P具有多个安装孔221P，所述飞轮壳30P具有一发动机穿孔301P、一电机穿孔302P、多个发动机限位孔303P和多个电机限位孔304P，多个所述发动机限位孔303P环绕地分布于所述发动机穿孔301P周围，多个所述电机限位孔304P环绕地分布于所述电机穿孔302P周围；所述飞轮壳30P以所述发动机穿孔301P对应于所述发动机主体11P的一端，且所述发动机限位孔303P对应于所述发动机10P的所述发动机缸体12P的所述装配孔121的方式安装于所述发动机10P，所述发动机主体11P的一端穿过所述飞轮壳30的所述发动机穿孔301P；所述起动电机20P以所述安装部220的所述安装孔221P对应于所述飞轮壳30P的所述电机限位孔304P的方式安装于所述飞轮壳30P，且所述发动机主体11P的一端穿过所述飞轮壳30P的所述电机穿孔302P。进一步地，所述动力装置100P包括多个连接组件40P，部分的所述连接组件40P被安装于所述飞轮 壳30P的所述电机限位孔304P和所述发动机10P的所述发动机缸体12P的所述装配孔121P，进而藉由所述连接组件40P将所述飞轮壳30P固定于所述发动机10P，部分的所述连接组件40P被安装于所述飞轮壳30P的所述发动机限位孔303P和所述起动电机20P的所述安装部22P的所述安装孔221P，进而藉由所述连接组件40P将所述起动电机20P固定于所述飞轮壳30P，并使得所述起动电机20P被保持于所述发动机10P的一侧。进一步地，所述发动机主体11P穿过所述飞轮壳30P的所述电机穿孔302P的部分被可驱动地连接于电机主体21P穿过所述飞轮壳30P的所述电机穿孔302P的部分，进而所述电机主体21P能够带动所述发动机主体11P旋转。但是，现有的所述动力装置100P在组装和使用的过程中存在不少问题。
首先，通常通过增加所述飞轮壳30P的重量来保障所述飞轮壳30P具有足够的强度和刚性以支撑所述起动电机20P，并保证所述起动电机20P在运转过程中能够稳定地被保持于所述发动机10P的一侧。这样，所述飞轮壳30P的重量增加了所述动力装置100P的整体重量，使得所述动力装置100P难以实现轻量化。
其次，端面轴向定位的方式降低了所述动力装置100P的稳定定性能。具体来说，所述起动电机20P的所述安装部22P靠近电机主体21P的端部，所述起动电机20P的所述安装部22P的所述安装孔221P的延伸方形平行于电机主体21P的轴向方向，所述连接组件40P以平行于电机主体21P的轴向方式将所述起动电机20P固定于所述飞轮壳30P，比如说，利用一螺栓依次穿过所述飞轮壳30P的所述电机限位孔304P、所述起动电机20P的所述安装孔221P、一平垫圈和一弹簧垫圈，再藉由一螺母锁紧固定。并且，所述起动电机20P的所述安装孔221P靠近于所述起动端机20P的端部，所述起动电机20P通过端部轴向定位的方式被安装于所述飞轮壳30P。这样，所述飞轮壳30P支撑所述起动机20P的支撑面靠近所述起动电机20P的一侧端面，所述起动电机20P的中心远离所述起动电机20P的被支撑面，且所述起动电机20P的大部分结构处于悬空状态，容易造成所述起动电机20P的重心远离所述起动电机20P的被支撑面，进而造成所述起动电机20P在带动所述发动机10P转动的过程中，以及所述发动机10P在后续以预定速率运转的过程中，所述起动电机20P会产生剧烈震动。长期的剧烈震动会造成所述连接组件40P的连接出现松动，严重的可能导致所述连接组件40P脱离所述飞轮壳30P的所述电机限位孔304和所述起动电机20P的所述安装孔221P，进 而所述起动电机20P和所述发动机10P分离，造成所述动力装置100P无法正常作业。
另外，所述发动机主体11P和电机主体21P均需要穿过所述飞轮壳30P后才能够被连接，这样，增长了所述发动机主体11P和电机主体21P的长度，进而增大了所述动力装置100P的体积，不利于所述动机装置100P小型化。
