钢绳在滑轮或卷筒上绕进或绕出时,通常都允许有一定的偏斜。就卷绕机构的构件而言,这种偏斜应限制得越小越好,这就要求构件的布置距离增大,但这同结构要求往往发生矛盾。反之,如果偏角过大,钢绳会碰擦绳槽侧边,引起钢绳擦伤以及槽口缺损,造成跳槽现象。如果是卷筒上的钢绳,还易于与邻槽的绳圈发生卡擦现象,使钢绳磨损加剧。上述的
When the rope is wound on or around pulleys or drums, it is usually allowed to have some deflection. In the case of the components of the winding mechanism, this deflection should be limited as small as possible, which requires an increase in the arrangement distance of the components, but this often contradicts the structural requirements. On the contrary, if the declination is too large, the steel cord will rub the side of the rope groove, causing the steel wire abrasion and the notch defect, resulting in the phenomenon of job-hopping. If it is a steel rope on the reel, it is also easy to wipe the rope ring with the adjacent groove, which aggravates the wear of the steel rope. abovementioned
