技术领域
本发明涉及机械制造技术领域，特别涉及一种燕尾榫接的组合式叶轮结构。
背景技术
轮盘是旋转机械的重要组成部分，旋转机械在运行时，受到气动激振、机械激振等作用的影响，容易造成损坏，轮盘的整体加工是将一组叶片和叶片轮盘进行整体铸造，造价高，当某一部分损坏时，只能整体更换，维护困难且维护成本极高。
发明内容
本发明公开了一种燕尾榫接的组合式叶轮结构，属于机械制造技术领域，可解决旋转机械轮盘整体加工的不足以及维修不便的问题。
本发明解决其技术问题采取的技术方案是：一种燕尾榫接的组合式叶轮结构，包括轮盘瓣、辅盘，所述轮盘瓣包括燕尾式凸榫、榫槽、叶片、安装孔、轴孔凸起和轴孔，所述轮盘瓣的两侧分别设有燕尾式凸榫和榫槽，所述轮盘瓣之间通过所述燕尾式凸榫和所述榫槽相连接，所述辅盘包括连接孔和中心孔，所述中心孔套入所述轴孔凸起，所述连接孔通过螺纹连接与所述安装孔相连。
进一步地，所述辅盘的内径与所述轴孔凸起的外圆半径相同。
进一步地，所述轮盘瓣的个数若干，可根据具体情况进行调整。
进一步地，所述连接孔在所述辅盘均布，其个数与所述轮盘瓣的个数相同。
本发明的有益效果为：本发明的一种燕尾榫接的组合式叶轮结构，在每个轮盘瓣的两侧分别有燕尾式凸榫和榫槽，每个轮盘瓣的燕尾式凸榫均嵌入与之相邻的另一个轮盘瓣的榫槽中，榫接成为一个完整的中间带轴孔的叶片轮盘，并由辅盘进行固定，轮盘瓣具有互换性，可批量生产，与轮盘整体加工相比降低加工成本，解决了的维修不便的问题，从而延长了使用寿命。
