moment of inertia of the system increasing the performance or power capacity of the system as shown in fig7 a 7 b 8 a and 8 b a drive link 59 connects the input shaft 29 to the masses 33 by way of a drive yoke 53 so that when the input shaft 29 rotates the masses 33 rotate about the offset sprockets 35 an alternate method of input drive is shown in fig1 15 and 16 the input drive assembly 53 b is a drive box that replaces the drive yoke 53 see fig1 this configuration of input drive is a more compact design the shape of the drive box 53 b is shown as a simple rectangle for ease of presentation the shape or geometry of the drive box could be a cylinder such as in a torque tube or some other shape components of the drive box typically include a plate on each end and a coupling component between the plates referring to fig1 the drive bars 65 are mounted in a slightly elongated slot 55 alignment bars 67 can be spring loaded to create tension on the drive bars and thus tension on the timing belts or chains 63 when the transmission is not rotating this creates a more compact design and allows the springs to preload the timing belts or chains 63 so that the teeth on the sprockets 33 45 maintain position on the timing belts when the transmission is not spinning this spring loading also allows for less precise manufacturing tolerances and a simplified design fig1 a through 12f show an end view of.
