规格型号:橡胶弹簧
产品类别:橡胶弹簧
产品介绍:
橡胶弹簧:橡胶弹簧有内摩擦阻力比钢丝弹簧大得多,因而采用橡胶弹簧的振动筛机启动通过共振区时,出现的振幅比螺旋弹簧振动筛机要小得多。采用橡胶弹簧的共振振动机,其振幅比较稳定,但耗能比钢丝弹簧要大。
橡胶弹簧是振动设备中不可缺少的原因有以下几点:
1、橡胶弹簧传递声音的阻力比钢丝弹簧大的多,所以隔音比较好,工作时相对噪音小。
2、可以将振动筛要使用的弹簧制成各种不同形状,尺寸的制品。这样可以让结构更紧凑,更能有效的利用空间。
3、因为橡胶的弹性系数远比金属的小,而且随硬度的变化在较大的范围内变化,所以改变橡胶硬度,可以使弹簧获得不同的刚度,即同一形状的橡胶弹簧,其刚度也可以在一定范围内选取。还有改变弹簧的内部结构(如改变其中心孔的尺寸等),也可以改变弹簧的刚度。
4、振动筛橡胶弹簧三个方向的刚度,可根据实际需要尺寸进行设计。此外橡胶弹簧也可以同时承受剪切变形和压缩变形。
