Abstract

一种隔膜泵的曲轴，是涉及隔膜泵的曲轴结构的改进。本实用新型就是提供一种结构简单、易于加工制作的隔膜泵的曲轴。本实用新型包括直轴，其结构要点直轴上固定有中间偏心轮，中间偏心轮的两侧分别固定有具有齿轮的右偏心轮、具有齿轮的左偏心轮。

Description

一种隔膜泵的曲轴
技术领域：
本实用新型是涉及隔膜泵的曲轴结构的改进。
背景技术：
曲轴是隔膜泵的重要大型部件之一。现有的曲轴为一根直轴上具有三段偏心拐轴，其结构较为复杂，加工难度比较大。往往是由技术力量较强，设备更为完善的大型企业方可完成。
实用新型内容：
本实用新型就是针对上述问题，提供一种结构简单、易于加工制作的隔膜泵的曲轴。
本实用新型采用如下技术方案：本实用新型包括直轴，其结构要点直轴上固定有中间偏心轮，中间偏心轮的两侧分别固定有具有齿轮的右偏心轮、具有齿轮的左偏心轮。
本实用新型的有益效果：
由于本实用新型的直轴上固定有中间偏心轮，中间偏心轮的两侧分别固定有具有齿轮的右偏心轮、具有齿轮的左偏心轮；就可对中间偏心轮、右偏心轮、左偏心轮，分别制作加工，使加工制作简便的多，生产周期缩短；还可适合小型企业加工制作。
附图说明：
图1是本实用新型的结构示意图；
图2是图1的俯视图。
具体实施方式：
本实用新型包括直轴8，直轴8上固定有中间偏心轮4，中间偏心轮4的两侧分别固定有具有齿轮2的右偏心轮1、具有齿轮5的左偏心轮7。
左偏心轮7、右偏心轮1分别通过键6、键3固定于中间偏心轮4上。
使用时，左偏心轮7、右偏心轮1、中间偏心轮4分别通过连杆9上的轴10同介杆12上的十字头11相连；然后，分别通过介杆12、齿轮2、齿轮5将动作传动出去。
