摘　　要： 介绍新型带传动——弹性啮合与摩擦耦合带传动的结构、传动原理。在 PX- I型皮带传动试验机上 ,研究新型带传动的动力学性能 ,并与 O型 V带进行对比试验。结果表明 ,新型带传动的传动效率高于 O型普通 V带 ,有效拉力为 4 9N～ 98N时新型带传动效率稳定于 91 %～ 95% ;当预紧力达 2 2 .0 7N以上并且有效拉力在 0～ 1 0 7.0 8N范围内时 ,新型带传动的滑动系数稳定于 1 %～ 2 % ;当预紧力较小 ( 5.88N)时 ,新型带传动有效拉力达98N左右发生打滑 ;当达到临界预紧力值后新型带传动达到最大有效拉力 ,且保持相对稳定值 ;新型带传动的最大有效拉力明显大于 O型普通 V带的最大有效拉力。试验与理论研究结果一致。 A new type of belt transmission, elastic engagement and friction coupled belt transmission structure and transmission principles are introduced.On the belt test machine,type PX-I dynamics properties of the new type of belt transmission are studied, and compared to the type of common V-belt under the same test conditions. Test results show that the transmission efficiency of the new type of belt is greater than that of the type of common V-belt and is steady in 91~95% when effective pull force is in the range of 49~98N. When the pull force in advance is beyond 22.07N and the effective pull force is in the range of 0~107.08N, sliding coefficient of the new type of belt is steady in 1~2%. When the pull force in advance reaches to 98N, the new type of belt transmission loses effectiveness. When pull force in advance is beyond the critical value,the effective pull force of the new type of belt will reach to the greatest value and keep in stable value, and the greatest effective pull force of new type of belt transmission is obvious greater than that of type of common V-belt. Test and theoretical results are identical. The new type of belt transmission is inexpensive.
