¡öApplication scope£º

¡ñSWP series universal coupling mainly applies to steel rolling, lifting and transportation machinery and other heavy machinery. It connects transmission shaft system of two different axis. Its tactical diameter is 160-640mm£¬transmission rated torque is 16¡«125kN¡¤m£¬the axis folded angle is ¦Â¡Ü10¡ã¡£

¡öForms:

¡ñSWP universal coupling is divided into A¡¢B¡¢C¡¢D¡¢E¡¢F¡¢and G seven forms.

¡öThe selection of universal coupling:

¡ñCalculated according to computed torque Tc:

[T]¡ªallowed torque£¬N¡¤m£¬ selected according to standard, which is the theory calculated value under given condition.

i.e. the revolution of coupling is n=33.3r/min, service life Lh=5000h,axis folded angle¦Â=3¡ã and load stable value.

Ka¡ªload character coefficient

¡ñRegarding high revolution, big folded angle or the length out of the standard coupling, except for the above calculation, also should calculate its critical revolution and the possibility of flexible rotation. The possibility of flexible rotation is denoted by

n¦Â, usually n¦Â<1800.
