Description

无键联结发动机水泵
技术领域
本实用新型属于水泵的技术领域。具体的说是水泵轴与皮带轮的联结。
背景技术
目前，公知的发动机水泵构造是由前端盖，与前端盖连接构成泵体的后端盖，装在泵体内一端伸出前端盖的泵轴，装在泵体内泵轴上的叶轮，装在泵体外泵轴上的皮带轮等构成，皮带轮与泵轴间多采用键联结，但在使用的过程中，经常出现滚键现象，影响发动机水泵的质量和使用。从而造成发动机的损坏。
发明内容
为了避免滚键现象的发生，省略键及键槽的加工工序，降低成本，使皮带轮与泵轴的联结更可靠，本实用新型提供一种结构简单的无键联结发动机水泵。
本实用新型解决其技术问题所采用的方案是：无键联结发动机水泵，包括包括水泵壳体，连接在水泵壳体上的后端盖，装在水泵壳体内一端伸出泵体的泵轴，装在水泵壳体内泵轴上的叶轮，伸出水泵壳体的泵轴上压装有皮带轮，且皮带轮与泵轴过盈配合。
本实用新型的有益效果是，省略了键及键槽，同时也省略了键及键槽的加工工序，相对减小了轴径及皮带轮内园壁厚，降低了成本，联结可靠方便，不出现滚键现象。
附图说明
下面结合附图和实施例对本实用新型作进一步说明
附图是无键联结发动机水泵的剖视图；
图中：1、皮带轮，2、泵轴，3、轴承，4、水泵壳体，5、水封，6、水管接头，7、叶轮、8、水泵后盖、9、轴承、10、隔套、11、圆柱固持剂。
实施例
如图所示的无键联结发动机水泵，包括水泵壳体4，通过螺杆与水泵壳体4连接的水泵后盖8，通过轴承3和轴承9及中间隔套10装在水泵壳体4内一端伸出水泵壳体4的泵轴2，装在水泵壳体4内泵轴2上的叶轮7，装在水泵壳体4与泵轴2间的水封5，设在水泵壳体4上的水管接头6，泵轴2与叶轮7过盈配合，皮带轮1与泵轴2过盈配合、且过盈配合处涂有圆柱固持剂11。
