Product introduction A：爪型齿状联轴器的设计 A: Design of a claw type rack coupler 三件一体的联轴器设计包括了带有曲面设计的轴毂和弹性体 The three - piece coupling is designed to include a shaft hub and an elastomer with a curved surface. ，用有限元素分析法设计的轴毂安全. 可靠. 运行平稳，轴毂可 The axle hub designed with the finite element analysis method is safe, reliable, smooth running, and the hub hub is available. 按客户的不同要求由合金铁、钢、铝、铸铁或球墨铁制成。不同硬度的聚氨酯弹性体能够弥补一定范围的角向、轴向和径向的位移。简洁的三件一体设计也更方便了设备安装。爪型齿状联轴器有绝缘免维护等特性，而且也不需任何润滑。弹性体的独特设计在即使是在破损的情况下都能保持正常工作状态（失效安全设计）。 It is made of alloy iron, steel, aluminum, cast iron or ductile iron according to the different requirements of the customer. The hardness of the polyurethane elastomer can compensate for a certain range of angular, axial and radial displacement. The simple three - piece design is also more convenient for the installation of the equipment. The claw shaped gear coupling has the characteristics of insulation and maintenance, and no lubrication is required. The unique design of the elastomer can maintain normal working condition (failure safety design) even if it is damaged. 两个轴毂的曲线爪在圆周方向上相互错开半个齿距，在其间装入一个渐开线的曲线爪型弹性体，弹性体的渐开线弧面能有效避免应力集中，补偿纠正由安装所引起的径向、轴向和角向的偏差。由于爪型联轴器的弹性体在运转时只承受压力，因而能够承受更大的负荷和扭矩，而且耐磨性能更好，寿命更长。 The curve claw two hub are offset in the circumferential direction on the half pitch, in which elastic claw type curve in an involute involute arc body, the elastic body can effectively avoid the stress concentration caused by the installation of compensation to correct the radial, axial and angular deviation. Because the elastic body of the claw coupling is only subjected to pressure when running, it can withstand greater load and torque, and has better wear resistance and longer life. 爪型弹性体材料（见右图） Claw elastomer material (see right) 产品提供四种爪型弹性体设计。具有高弹性、抗磨损和缓冲性能强的特性。一系列具有不同硬度的弹性体也可满足客户对产品扭矩. 缓冲性能和抗化学污染等不同要求。其中，92SHA硬度的弹性体（白色或黄色）为标准型，有最佳的扭矩传输能力.标准型弹性体为中空状，允许传动轴之间有较小间隙。所有的标准型爪型弹性体的额定工作温度为80°C。（详情请查ZS型弹性体温度适用标
