friction plates 38 if the drive mechanism of the present system is configured to comprise a pinion gear 16 and a driven gear 18 it may be desirable to quiet noise generated by driven gear 18 and driving gear 16 this gear noise typically being most predominant at low load conditions the solution to this problem is to maintain positive tooth engagement between the two gears by applying a controlled drag torque on driven gear 18 in the present system as disclosed the drag torque is a function of an annular ring friction interface similar to that used in the drive torque limiter as with that mechanism the drag torque provided by the drag plate of the present system is a function of the annular ring drag surface radii the friction coefficient of the interface and the bias or spring force used in biasing the drag plate toward the driven gear use of a drag plate such as the one disclosed in the present system allows highly reproducible torque to be achieved by the system while also allowing use of low cost low precision gears which are noisy without a backlash quieter but which can be quieted in a highly controlled manner in a long life system through the present drag plate accordingly the present system comprises a drag plate 28 comprising a substantially rigid plate a hole 54 is located.
