SWPF型大伸缩单型万向联轴器的共同特点是角向补偿量较大,不同结构型式万向联轴器两轴线夹角不相同,一般≤5°-45°之间。万向联轴器利用其机构的特点,使两轴不在同一轴线,存在轴线夹角的情况下能实现所联接的两轴连续回转,并地传递转矩和运动。万向联轴器的特点是具有较大的角向补偿能力,结构紧凑,传动。SWPF型大伸缩单型万向联轴器是一种   常用的联轴器。利用其结构的特点能使不在同一轴线或轴线折角较大或轴向移动较大的两轴等角速连续回转,并地传递转矩和运动。能广泛应用于冶金、起重、工程运输、矿山、石油、船舶、煤炭、橡胶、造纸机械及其它重机行业的机械轴系中传递转矩。

SWPF型大伸缩单型万向联轴器的主要特点为:

1. Has a large angle compensation capability.

2. The structure is compact and reasonable. The SWC type uses an integral fork to make the carrier more flexible.

3. Large carrying capacity.Compared with other types of couplings with the same rotating diameter, the torque transmitted by it is larger. This is superior to the range of matching mechanical equipment with restricted rotating diameter.

4. Transmission.Its transmission efficiency is 98-99.8%, which is used for high-power transmission and energy saving.

5. Stable transportation, low noise, easy assembly and disassembly and maintenance.

对严重冲击载荷或要求轴系扭转振动的传动,可选用轮胎式联轴器等具有高弹性的联轴器。SWPE型(有伸缩法兰长型)十字轴式万向联轴器的工作转速高低和引起的离心力大小。对于高速传动轴,应选用平衡精度高的联轴器,例如Diaphragm coupling等,而不宜选用存在偏心的滑块联轴器等。联轴器由两半部分组成,分别与主动轴和从动轴联接。一般动力机大都借助于联轴器与工作机相联接。

为克服双联十字轴万向联轴器的缺点,令图1中间轴的长度缩短为0,即取消中间轴,而将两十字轴相应变为十字轴和十字环的结构,则   环叉式等角速万向联轴器。为满足匀速运动特性,尚须增加一套分度机构,此机构类似于球笼式万向联轴器的杠杆式分度机构,这就达到了万向联轴器传力点的运动平面是主、从动轴的角平分面的等速传动条件。

分析得出当环叉式万向节存在分度误差时,对等角速性有   影响,但其影响很小,因而环叉式万向节的等角速性是   可以的。环叉式万向节的匀速性与RzEPPA型球笼式万向节接近。
