                          电玩城游戏大厅 同步带轮常见问题

                          带和同不带轮的结构


                          846


                          1.结构组成

                          顶胶,抗拉体,底胶和包布

                          2.截面型号:Y,Z,A,B,C,D,E

                          3.基本参数:

                          节宽bp,基准宽度bd,基准直径dd,基准长度Ld(指按带轮基准 直径dd 计算的数值)等.

                          4标记:

                          由截面代号和基准长度组成,

                          A1600表示A型V

                          基准长度为1600mm.

                          8.2.1 普通V带的结构和尺寸标准

                          8.2.2 普通V带轮的材料和结构

                          1.材料

                          铸铁:υ300

                          V带轮结构图

                          (a)实体结构;(b)腹板式;(c)孔板式; (d)轮副式

                          平带与V带的比较

                          σb2

                          带截面产生的应力包括三个部分:

                          1.由拉力产生的拉应力

                          2.由离心力产生的拉应力

                          3.由弯曲产生的弯曲应力

                          带的应力分布图

                          max=σ1+σb1+σc

                          由图可知,带上最大应力发生在带的紧边进入小带轮处
