Hi everybody. I have a electrical actuator that works with a simple worm gear as a gear box and has 3 types.but the siz of worm gear set is equivalant in all of them.the spepecifications are: Type 1: Input rpm 1500 Input torque 80 Nm Power 310 w Output rpm 18 Output torque 204 Nm Efficiency 44 Type 2. Input rpm 1500 Input torque 30 Nm Power 630 w Output rpm 48 Output torque 204 Nm Efficiency 54 If attention, in three of them output totque is equivalant. How can design this worm gear. Wich parameters are changed?pay attention the size must be constant.
