The calculation results show that the automatic tensioner is to guarantee the pulling force of tension release in belt gearing and the non-automatic tensioner is to guarantee the pretension .

计算结果表明：自动张紧器保证的是 皮带 传动中松边拉力F2，而非自动张紧轮保证的皮带预紧力Fo。

When the sprocket or pulley shaft installed in the effort Chain / conveyor belt transmission mode can be intermittently Transmission Pipeline - automated machinery . gearing with the thread of a worm .

当链轮或皮带轮安装在出力轴上时，链/ 皮带传动的输送方式可间歇地 传动流水线式的自动化机器。

This thesis on research dynamical loads on rubber transmitting belts used in driving pumping unit with long-stroke especially the influence of the elasticity on rubber transmitting belts and work condition is discussed . Analysis on improving the SDJ - 150 rubber belt conveyer gearing

分析了长冲程抽油机传动胶带中的动载荷，重点讨论了胶带弹性及抽油机工况对动载荷的影响。SDJ-150型 胶带输送机 传动 装置的改进
