                              同步带轮挡圈的铆合工艺


                              同步带轮挡圈的铆合工艺


                              我厂近几年的新产品开发中,同步带传动正以它传动平稳、可靠性高、结构简单、制造方便和噪音低等优点广泛直用在新产品的机械传动中,并不断替代链条传动和齿轮传动,成为纺织机械中的一种新的传动形式。根据同步带传动的特点和使用要求,有些同步带轮的两边必须铆台挡圈(图1),以限制同步带在工作过程中的左右窜动。
                              我厂在进行同步带轮挡圈的铆合过程中,不断摸索和革新,在不增加任何专用设备的情况下.应用旋压工艺和技术,在普通卧式车床上使用旋压工具对挡圈进行旋压铆合,使其铆合质量和强度都超过设计要求。

                              一、挡圈铆台的工艺过程

                              1.挡圈铆合的现状

                              2.同步带轮的旋压铆台工艺
                              为了把挡圈牢固地铆台在同步带轮上,我们采取了在同步带轮两端面圆周上加工出9O的V型沟槽,作为旋压铆合的施压部位(图2)为了旋压铆合时使挤压金属产生均匀的塑性变形,达到牢固铆台挡圈的目的,一般选择V型沟槽深1.5ram,沟槽中心到外圆距离为2.5~3.5ram。为保证同步带轮与挡圈的配台问隙及铆台质量,一般选择它的配合形式为过渡配合。例如图1所选择的配合公差即为H8/js7。为了得到较好的旋压效果,使材料的组织结构及应力状态对变形有利,一般对中碳钢材料的同步带轮需进行调质处理,以达到既利于旋压变形,又可提高工件综合性目B的目的。

                              同步带轮的旋压转速与挡圈的铆合质量是密切相关的。过高的转速固然可以提高生产效率,但往往还会引起机床振动及工件的发热生温,过热的金属受压后往往会向同步带轮的轴线方向延伸和发生较大的塑性变形,并造成金属的疲劳和晶粒的破碎,使旋压铆台表面粗糙度恶化和铆台强度不够。
