一、测定的意义和目的衬垫对钢绳的附着系数是摩擦传动机械的重要设计依据。提高附着系数是提高摩擦传动机械设备能力的一个多、快、好、省的途径。如包角为240°,附着系数为0.2和0.4时,钢绳紧边与松边张力比分别为1.0及2.31;当附着系数提高到0.6时,钢绳紧边与松边张力比可达12.33。或者说,当附着系数为0.3时,包角应为240°;如附着系数降低到0.2,则包角应为 First, the determination of the meaning and purpose Pad adhesion coefficient of the rope is an important friction transmission machinery design basis. Increase the adhesion coefficient is to improve the friction transmission machinery and equipment capacity of a more, faster, better, provincial way. When the wrapping angle is 240 ° and the adhesion coefficient is 0.2 and 0.4, the tension ratio between the tight side and the loose side of the steel cord is 1.0 and 2.31, respectively. When the adhesion coefficient is increased to 0.6, the tension ratio between the tight side and the loose side of the steel cord can reach 12.33 . In other words, when the adhesion coefficient is 0.3, the wrap angle should be 240 °; if the attachment coefficient is reduced to 0.2, the wrap angle should be
