Abstract

一种电动自行车新型谐波减速机构，在电动自行车谐波减速机构基础上，将电动机转子直接固定在谐波发生器套筒外径成为一体，和谐波柔轮同时直接由自行车中轴支撑，省略了原谐波减速机构中的谐波柔轮套筒，本实用新型的有益效果是，省略谐波柔轮套轴增加了电动机径向空间，因此可以压缩电动机轴向尺寸，从而压缩了驱动机整体的轴向尺寸；省略谐波柔轮套轴使结构更加简单，结构刚性更好，安装更加方便，降低成本。

Description

电动自行车新型谐波减速机构
所属技术领域
本实用新型涉及一种电动自行车新型谐波减速机构。
背景技术
本发明人发明的《电动自行车谐波减速机构》于2005年8月3日获得授予专利权，专利号为ZL 2004 2 0020086.6。在实际应用中对该项设计进行试验改进后，谐波发生器、谐波柔轮同时直接由自行车中轴支持，省略了谐波柔轮套筒，提高了该机构性能。
发明内容
本实用新型的目的是提高原有电动自行车谐波减速机构的性能、简化结构、降低成本。
本实用新型所采用的技术方案是：在电动自行车谐波减速机构基础上，将电动机转子直接固定在谐波发生器套筒外径成为一体，与谐波柔轮和自行车中轴同在一个轴心，和谐波柔轮同时直接由自行车中轴支撑，谐波柔轮、谐波发生器分别由轴承支撑连接，同时在自行车中轴上运转，省略了原谐波减速机构中的谐波柔轮套筒。
本实用新型的有益效果是，省略谐波柔轮套轴增加了电动机径向空间，因此可以压缩电动机轴向尺寸，从而压缩了驱动机整体的轴向尺寸；省略谐波柔轮套轴使结构更加简单，结构刚性更好，安装更加方便，降低成本。
附图说明
下面结合附图对本实用新型进一步说明。
图1是新型谐波减速机构结构图，图中(1)电动机转子、(2)谐波发生器、(3)自行车中轴、(4)谐波柔轮。
图2是原谐波减速机构结构图，图中(5)谐波柔轮套轴，在本实用新型中被省略。
具体实施方式
在图1中，(1)电动机转子与(2)驱动谐波发生器一体，和(4)谐波柔轮同时直接在(3)自行车中轴上运转。
