进口铝合金顶丝式梅花联轴器 产品用途 Product use进口铝合金顶丝式梅花联轴器2.jpg

1.具有补偿两轴相对位移、减震、缓冲的功能,径向尺寸小、结构简单、不用润滑、承载能力高、维护方便 It has the functions of compensating the relative displacement, damping, and buffering of two shafts, with small radial size, simple structure, no lubrication, high bearing capacity, and convenient maintenance

2.工作环境温度-35~80℃ Working environment temperature - 35~80 ℃

3.主体采用高强度联轴器专用铝制成,中间弹性体采用聚氨脂制成,具体良好的耐磨性,耐油性和电气绝缘性 The main body is made of high-strength aluminum for couplings, and the intermediate elastomer is made of polyurethane, which has excellent wear resistance, oil resistance, and electrical insulation

4.通常用于伺服电机,步进电机连接 Usually used for servo motor and stepper motor connection


结构特点 Structural features

1.零回转间隙,适用于正反转 Zero swing clearance for forward and reverse rotation

2.中间弹性体可吸收振动,补偿径向,角向和轴向偏差 Intermediate elastomer absorbs vibration and compensates for radial, angular, and axial misalignment

3.可拆式设计,方便安装拆卸.定位螺丝紧固方式  Removable design for easy installation and disassembly. Fastening method of positioning screws
