LT type (formerly TL type) elastic sleeve pin coupling detailed parameters
　　LT type (formerly TL type) elastic sleeve pin coupling (GB4323-2002 instead of GB4323-1984) elastic sleeve pin coupling uses a pin with an elastic sleeve (rubber material) at one end, which is installed in the two halves In the flange hole of the shaft, to realize the coupling of the two halves of the coupling.The elastic sleeve pin coupling was once the most widely used coupling in our country. The JB08-60 elastic ring pin coupling was the first standard coupling in my country.
　　Calculating torque Tc: Calculate with the following formula
　　Tc=KT
　　T=9550×Pw/n=7020×PH/n
　　Where T=theoretical torque Nm
　　K—working condition coefficient, please refer to JB/ZQ4383-86 "Coupling load classification and working condition coefficient" for selection.
　　Pw —drive power, Kw
　　PH—drive power, horsepower
　　n—speed, rpm

　　Determine the shaft diameter and the form of the key (or expansion coupling sleeve).
