2.工作环境温度-35~80℃ Working environment temperature - 35~80 ℃
3.以工程塑料作弹性元件,缓冲、减振、耐磨 Using engineering plastics as elastic elements for cushioning, vibration reduction, and wear resistance
结构特点 Structural features
尺寸紧凑,惯性小,承载能力高 Compact size, small inertia, high bearing capacity
具有补偿两轴相对位移、减震、缓冲的功能 It has the function of compensating the relative displacement of two shafts, damping, and buffering
两同轴线、启动频繁、正反转多变的轴系传动 Shaft transmission with two coaxial lines, frequent starting, and variable forward and reverse rotation
双部件双节式结构能补偿很大的安装偏差 Double component and double section structure can compensate for large installation deviation
阻尼振动,降低噪音 Damping vibration and reducing noise
偏差引起的力很小 The force caused by the deviation is very small
