In this system, the final gear is connected to the gearbox output shaft by means of a friction assembly. In some cases, this device can be used for time adjustment or zero reset on timers. The standard torque setting is from: - 1.8 to 2.5 cm/kg for gearbox 810210 - 7 to 10 cm/kg for gearbox 810330 Principles Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected02/11/2015 www.crouzet.com This device, situated inside the gearbox, enables the output shaft to be rotated by an external force (manual or mechanical) independently of the final wheel of the gearbox. Description A specially shaped cam (1) is directly fitted on the gearbox output shaft. The final wheel (2) of the gearbox pivots freely on this shaft and has a housing into which the cam fits (1). Between the cam and final wheel two rollers are symmetrically located held in place under the pressure of two springs (4). When the geared motor is energised, it causes the final wheel (2) to rotate which, via the two rollers (3), in turn drives the output shaft. If, under external force, the output shaft is turned in the same direction as the final wheel but at a higher speed, the two rollers (3) release the final wheel and the shaft speed becomes independent of the speed of the final wheel. The rollers can be located according to whether the final wheel is rotating clockwise or anti-clockwise. Can be used with gearboxes 810210 and 810330. o Legend N Dimensions (mm) 823440 o Legend N 2 fixing holes 3.2 (pushed-in shaft) 3.5 across flat Fixing clip Dimensions (mm) Shaft 79200967 o N Legend (pushed-in shaft ) Dimensions (mm) Shaft 79200779 Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected
