LJ radial elastic pin coupling

The difference between the LJ radial elastic pin coupling and the elastic pin coupling is that it inserts several nylon cylindrical pins into the semi-cylindrical grooves on the flange end faces of the main and driven half couplings. In the radial cylindrical hole, the two halves of the coupling are difficult for the pin to transmit torque. Due to the large bearing area of ​​the pin, the bearing capacity is high and the performance is good.In order to prevent it from coming out, a stop circle is installed on the outer end of the pin.This kind of coupling has the ability of damping and buffering and compensating the relative displacement of the two shafts (x, y=1mm, =0.35°-1), the two halves of the coupling need not be moved when changing the pin, and the working environment temperature is- 35-85℃, its disadvantages are uneven force on each pin.

LJ radial elastic pin coupling calculation torque Tc: use the following formula to calculate 

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).
