本实用新型提供一种饼式电动机传动连接机构，设有电机转轴、轴套和工作轴，轴套和工作轴通过工作键连接，电机转轴设有内花键，轴套外设有外花键，内花键和外花键形成花键啮合连接，外花键为球齿式外花键。
优选地，外花键为球齿式渐开线花键。
优选地，花键啮合处均布设有润滑脂。
优选地，润滑脂通过密封条密封，密封条与轴套外周和电机转轴内周构成封闭空间密封润滑脂。
优选地，轴套外端设有轴端挡板，轴套通过轴端挡板及工作键固定在工作轴上。
优选地，电机转轴轴伸处设有安装盘，安装盘通过螺纹连接与电机转轴紧固。
本实用新型的有益效果是：
本实用新型采用球齿式渐开线花键，电机转轴与设备工作轴直联时，允许一定程度的偏摆，在不超过3°的偏摆时保持电动机运转平稳，延长电动机的使用寿命，同时能够承受较大的工作载荷；
本实用新型通过密封条形成润滑脂的密封，结构简单，密封效果好；
