                            高压锅不松动手把的研究与设计

                            2013/5/23 14:16:57

                            前高压锅手把与连接块之间没有导向定位结构,仅靠旋紧螺钉产生的力来得到固定,且在倾斜锅体时仅靠
                            摩擦力传递扭矩,这种结构容易产生松动。在对传统高压锅手把的工作原理及缺点进行大量分析研究后,研
                            制了一种新型高压锅不松动手把,通过啮合力代替摩擦力,以增大扭矩,并对其进行综合性能实验,实验结果
                            表明,该新型手把是一种不易松动、寿命长、适用性强的高压锅手把。1 引言

                                    常温下,由于存在预紧力,螺钉的紧边始终紧贴连接块内螺纹向外的边,而松边与连接块内螺纹向里的边有间隙; 高温下,由于螺钉、连接块、手把的材质不同,其热膨胀系数也不相同。如果螺钉的热膨胀系数大于连接块的热膨胀系数,螺钉的紧边与连接块内螺纹向外的边会贴的更紧,同时螺钉的松边与连接块内螺纹向里的边之间的间隙更小,甚至接触,这种情况下,螺钉在高温下会拧得更紧; 如果螺钉的热膨胀系数小于连接块的热膨胀系数,螺钉的紧边与连接块内螺纹向外的边之间的压力会变小,但松边与连接块
                            内螺纹向里的边之间的接触压力会增大,这种情况会使螺钉在高温下变松。在由高温到低温的过程中,无论是螺钉、连接块,还是手把都不可能回到原始的状态,因而,第一种情况下,螺钉的预紧力会小于高温下的预紧力,第二种情况下,螺钉的预紧力会小于原始
                            常温下的预紧力。无论是哪种情况,螺钉在使用过程中都会变松。
