根据JB5513-2006标准 ，SWC-I和SWC型万向联轴器按下列方法选型。其它型号万向轴的选择请用户来电详询。

　　According to the JB5513-2006 standard, the SWC-I and SWC type universal joints are selected in the following manner.For other models of universal joint shaft, please call us for details.

　　1、万向联轴器应根据载荷特性、计算转矩、工作转速选用。

　　1. Universal coupling should be selected according to load characteristics, calculated torque and working speed.

　　2、计算转矩由式（1）、式（2）或式（1）、式（3）求出：

　　Tc=KT..........(1)

　　工作情况系数K

　　万向联轴器联接法兰 Flange Connections 

　　万向联轴器一般是通过两端外侧叉头的法兰与配套法兰轴套的法兰相联。叉头的法兰有下图所示四种结构型式，分别为纯螺栓孔连接法兰、端面键联接法兰、牙嵌式联接法兰和端面齿联接法兰。

　　The universal joint shagt is normally connected to the flange adapters at both ends by flanging and bolting the flange adapters.There are four types of flange connections as shown below.

　　万向联轴器通过高强度螺栓与螺母把两端法兰盘联接在其他相配配件上，两者都以止口定位加工，以保证联接起来后的同心度。The universal joint connects the flanges at both ends to other matching fittings through high-strength bolts and nuts, and both are positioned by the nozzle to ensure the concentricity after joining.

　　联接螺栓只能从相配件的法兰侧装入，螺母由万向轴侧预紧。螺栓10.9级，螺母10级。需从万向轴端装入螺栓时要预定注明。

　　The coupling bolt can only be inserted from the flange side of the phase fitting and the nut is pretensioned from the cardan shaft side.Bolt 10.9, nut 10. Be sure to specify when loading the bolt from the cardan shaft end.

　　配套法兰轴套的说明 Companion Flange Adapters

　　与万向联轴器配套的法兰轴套按用户要求单独提供。要求提供法兰轴套的用户，订货时应向我厂提供设计图纸，或提出明确要求由我厂代为设计。供设计法兰轴套所需的数据，请用户确定轴套型式（圆孔或扁孔）后，填入下表中传真给我厂。

　　The companion flange adapters are provided separately on request.Customers requesting flange adapters can either provide us with relevant drawings,or specify requirements for customized designing.If you need our assistance in companion flange designing,please determine the type of companion flange required (cylindrical bore or flat bore)，Fill in the form below and fax it to our factory.
