Description

单缸汽油机及风冷式柴油机的曲轴
技术领域
本实用新型涉及单缸汽油机及风冷式柴油机的曲轴,属机械动力设备的制造领域。
背景技术
单缸汽油机及风冷式柴油机的曲轴在回转中受到缸体交变的气体冲击力、往复惯性力和离心力以及由其所引起的弯矩、扭矩的作用。这些力不仅随曲柄转角变化,也随负荷变化。曲轴的形状复杂,截面变化多,刚性要求高,受力复杂,很容易造成疲劳破坏。现有曲轴臂的两个端面呈斜面状结构,扇形面与曲轴臂的连接也按各自的几何形状进行简单的连接,传统的改进方法主要是通过加工制造工艺的改善来进行提高,如:通过降低粗糙度来提高表面的质量,过渡圆角进行滚压来提高疲劳强度,虽然会有一定的效果,但效果有限。
实用新型内容
本实用新型为了能更有效的提高曲轴的强度,提供了一种单缸汽油机及风冷式柴油机的曲轴,通过改变结构,改善曲轴的强度。
本实用新型的技术方案是:
一种单缸汽油机及风冷式柴油机的曲轴,包括输入端、输出端、左扇形面、右扇形面和曲轴臂,所述的左扇形面与所述的输入端连接,所述的右扇形面与所述的输出端连接,所述的左扇形面、右扇形面通过所述的曲轴臂连接,其特征是:所述曲轴臂的两个端面呈球面状。
本实用新型具有结构简单、成本低、提升曲轴强度明显的有益效果。
附图说明
图1为本实用新型单缸汽油机及风冷式柴油机的曲轴的整体结构示意图。
图2为本实用新型单缸汽油机及风冷式柴油机的曲轴的侧视图。
具体实施方式
现结合附图对本实用新型作进一步的说明:
如图1、图2所示,一种单缸汽油机及风冷式柴油机的曲轴,包括输入端11、输出端12、左扇形面41、右扇形面42和曲轴臂3,左扇形面41与输入端11连接,右扇形面42与输出端12连接,左扇形面41、右扇形面42通过曲轴臂3连接,曲轴臂3的两个端面呈球面状31。
