齿形联轴节外齿轴套的齿顶是半径为R(?)的球面形(图1),但因这种结构安装倾角较小(30＇),实际使用中安装困难,润滑效果差,使用寿命短,所以目前在冶金设备中,尤其在轧钢设备中,采用了弧形齿面的外齿轴套的齿形联轴节(图2),安装倾角可达4°～5°,便于安装,润滑效果好。我厂在无专用设备条件下,采用普通滚齿机加工弧形齿轮效果较好,现介 Tooth-shaped coupling outer gear sleeve tooth tip is a radius of R (?) Spherical (Figure 1), but because of this structure to install a small angle of inclination (30 ’), the actual use of the installation difficult lubrication effect is poor , The service life is short, so at present in the metallurgical equipment, especially in the rolling equipment, the use of curved gear tooth gear sleeve coupling (Figure 2), the installation angle of up to 4 ° ~ 5 °, Easy to install, good lubrication effect. I plant in the absence of special equipment conditions, the use of ordinary gear hobbing arc gear better, now
