Description

适用于内啮合减速传动的高压清洗机电机泵单元 技术领域
本发明涉及电机装置领域，具体地，涉及一种适用于内啮合减速传动的高压清洗机电机泵单元，尤其涉及一种用于内啮合减速传动的电机以及电机支架。

高压水射流清洗技术是一门高效节能的物理清洗技术，高压清洗机是目前世界上公认的最环保、最经济、最科学的清洁设备，在工业、商业、民用等领域应用非常广泛。以串激电机(或直流电机)为动力的高压清洗机电机泵单元由高压泵组件、油缸组件、高压清洗机电机泵单元等组成。高压清洗机电机单元输出端设置有小齿轮；油缸组件设置有大齿轮，齿轮轴、斜盘以及平面轴承；高压泵组件设置有柱塞、水封、单向阀等增压元件。工作时，电机小齿轮通过与大齿轮啮合减速后通过由斜盘支撑的推力轴承驱动泵的柱塞做往复运动，实现泵的增压功能。目前传统的减速装置采用的是外啮合传动。这种外啮合结构大小齿轮传动时两齿轮重合度小，传动连续性较差，噪音较高；同时，由于离心力的作用，外啮合的结构润滑脂容易受离心作用而甩离齿面导致，齿轮润滑变差、寿命变短。
专利CN201081005Y中公开了一种内啮合传动结构，以及一种外啮合结构，在内啮合方案中，由于其大齿轮是依靠推力轴承进行径向定位的，其定位精度低，会导致传动的不稳定---特别是在启动的瞬间。而其公开的外啮合方案由于齿轮属于外啮合，齿轮重合系数低，齿轮传动稳定性较差；而且外啮合两齿轮(也即电机与泵)的中心距相对内啮合方案的大，因此，外啮合方案不仅其电机支架本身需要更大的尺寸，其电机泵尺寸也会变大。
