LT type (formerly TL type) elastic sleeve pin coupling
Summary: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) on one end and is installed in the two halves In the flange hole of the shaft, to realize the coupling of the two halves of the coupling.
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 used to be my widely used coupling. The JB08-60 elastic ring pin coupling is our standard coupling.
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).
