Note: 1. Allowable speed refers to the allowable speed within the range of 1 ° of angular compensation.
2. LD1~LD6 multi angle rubber elastic parts are hexagonal.
The LD7-LD11 multi angle rubber elastic parts are octagonal.
3. The combination types of coupling shaft holes include Y-J1, Y-Z, J1-Z1, Y-Y, J1-J1.
4. The instantaneous impact torque is greater than 2-3 times the nominal torque.
5. The moment of inertia and mass are approximate calculated values of the maximum values among various models.
