                              电玩城游戏大厅 同步带常见问题

                              梯形齿同步带分单面有齿和双面有齿两种

                              同步带是以钢丝绳或玻璃纤维为强力层,外覆以聚氨酯或氯丁橡胶的环形带。带的内周制成齿状,使其与齿形带轮啮合。按齿形分为梯形齿和弧齿两类,弧齿又有3种系列:圆弧齿(H系列又称HTD带)、平顶圆弧齿(S系列又称为STPD带)和凹顶抛物线齿(R系列)。
                              梯形齿同步带分单面有齿和双面有齿两种,简称为单面带和双面带。双面带又按齿的排列方式分为对称齿型(代号DA)和交错齿型(代号DB)。
                              梯形齿同步带有两种尺寸制:节距制和模数制。我国采用节距制,并根据ISO5296制订了同步带传动相应标准GB/T 11361~11362-1989和GB/T11616-1989。
                              弧齿同步带除了齿形为曲线形外,其结构与梯形齿同步带基本相同,带的节距相当,其齿高、齿根厚和齿根圆角半径等均比梯形齿大。带齿受载后,应力分布状态较好,平缓了齿根的应力集中,提高了齿的承载能力。故弧齿同步带比梯形齿同步带传递功率大,比梯形齿高1.2~2倍,能防止啮合过程中齿的干涉,使用寿命较梯形齿更长。
                              同步带的耐油性、耐磨性、抗老化性、抗冲击性和抗振动性好,工作时噪声小,不需润滑,可用于有粉尘的恶劣环境。因此在设计上为常用选型,已在玻璃行业得到广泛应用。
