XinLan向大家介绍提高Drum gear coupling使用寿命的重要途径
提高鼓形齿式Coupling使用寿命的重要途径。齿宽系数影响轮齿的齿根弯曲强度和齿面接触强度,齿宽系数越大,这两项强度越大,齿宽系数影响重合度,在齿宽系数小于 值的范围时,其值的增大对重合度增加影响较大,而在大于这个 值时,器值的增大对重合度增加影响变小,对于圆弧鼓度曲线的鼓形齿式联轴器,齿宽还是确定鼓度圆半径也侧隙的参数,齿宽越大,鼓度圆半径越大,所需要的侧隙也越大,因此,需要以下亮点要求:在轴间倾角处于 大时不出现棱边接触现象;轮齿集中载荷越小越好,而齿面曲率与鼓度圆周率成正比,因此鼓度圆半径尽可能大。鼓度曲线曲率半径与内齿单侧减薄量成正比,因此鼓度圆半径应尽可能大。鼓度曲线曲率半径与内齿单侧减薄量成正比,即它与齿的啮合 有关,减薄量不足可能会造成干涉,减薄量过大会削弱齿的强度,且会侧隙很大。
