柱销联轴器与三爪联轴器区别

梅花联轴器由两个带凸爪形装的半联和一个硬度可以调整的梅花形弹性非金属元件组成，利用梅花形弹性元件嵌入两个半联之间实现联接，梅花弹性联轴器具有补偿两轴相对位移，减振缓冲，结构简单，无需润滑维护方便等特点。

星形弹性联轴器是以工程塑料作弹性元件，适用于联接两同轴线的传动轴系，星形联轴器具有补偿两轴相对偏移、缓冲、减震、耐磨性能，适应场合普遍，传递转矩20-35000.N.M,工作温度-35-+80摄氏度。星型联轴器聚氨脂弹性体由凸形爪块限制。

梅花形联轴器以聚氨脂塑料为弹性元件与二半联轴器主体紧密组合,主体以进口配方合金铝为主。梅花型联轴器中间聚氨脂塑料元件以独有配方配制,具有耐磨性高抗温性好韧性强,与一般普通塑胶件质量稳定耐用. 梅花型体有六瓣和八瓣,根据客户要求定制. 固定方式有键槽.

爪式联轴器结构简单、无需润滑、方便维修、便于检查、免维护，可连续长期运行。高强度聚氨酯弹性元件耐磨耐油，承载能力大，使用寿命长，安全可靠。工作稳定可靠，具有良好的减振、缓冲和电气绝缘性能。三爪联轴器具有较大的轴向、径向和角向补偿能力。结构简单，径向尺寸小，重量轻，转动惯量小，适用于中高速场合。

The plum-shaped flexible coupling is composed of two semi-couplings with convex claws and a plum-shaped flexible non-metallic element whose hardness can be adjusted. By embedding the plum-shaped flexible element into the two semi-couplings to realize the connection, plum couplings has the characteristics of compensating the relative displacement of the two axes, reducing vibration and buffering, simple structure and easy maintenance without lubrication.

柱销联轴器是利用一端套有弹性套（橡胶材料）的柱销，装在两半联轴器凸缘孔中，以实现两半联轴器的联接。

弹性柱销联轴器是一种结构简单制造容易，无需润滑，装拆弹性柱销便捷的传动基础件，利用两个带法兰孔的半联和置于起重的非金属弹性柱销来传递扭矩，适用于中低速和中低扭矩场合。

弹性柱销齿式联轴器采用非金属弹性柱销和两个带齿形半联以及一个外圈的齿形套环设计，利用非金属弹性的变形来传递扭矩同时缓冲减震，补偿角向位移。

弹性套柱销联轴器设计简单巧妙，适用性较广的联轴器，利用带弹性套的柱销联接两个带销孔的半联，实现扭矩传递的同时兼具较大的角向补偿，同时减震缓冲性能良好，可以用在速度较快的场合，无需润滑，销套更换便捷。

The pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement. The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions. The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, Pin and bush couplings has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
