1、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。同步带传动时，传动比准确，对轴作用力小，结构紧凑，耐油，耐磨性好，抗老化性能好，一般使用温度-2080，v50m/s，P300kw,i10,对于要求同步的传动也可用于低速传动。同步带传动具有以下特点：（1）传动准确，工作时无滑动，具有恒定的传动比；（2）传动平稳，具有缓冲、减振能力，噪声低；（3）传动效率高，可达0.98，节能效果明显；（4）维护保养方便，不需润滑，维护费用低；（5）速比范围大，一般可达10，线速度可达50m/s，具有较大的功率传递范围，可达几瓦到几百千瓦；（6）可用于长距
