21. The winch drums were connected to the drive motor and the service brake by a gear train . 22. The gear train is like the skeleton. 23. For instance, a gear train is often characterised simply by its gear ratio, a SISO transfer function. 24. Cycle times of over 300, 000 have been observed with these gear trains showing virtually no wear. 25. The input gear in this gear train has 13 teeth and the idler gear has 21 teeth. 26. In a gear train , backlash is cumulative. 27. The planetary gear train also provides stability due to an even distribution of mass and increased rotational stiffness. 28. The pulse of electricity that drove the pendulum would also drive a plunger to move the gear train . 29. The load in a planetary gear train is shared among multiple planets, therefore torque capability is greatly increased. 30. Traction engine rotor is connected with a gear train through the rigid clutch ( rubber cord shell ).
