<p>#CMT# #/CMT# A watch movement has tensioned (30, 32) belt (20, 21) transmission between ball bearing mounted pulleys (150, 160, 170, 180) of the energy from several inclined barrels (15, 16, 17, 18) joined by a torque divider and charged by a mass (14) oscillating linearly between sprung stops. #CMT# : #/CMT# A watch movement has tensioned (30, 32) belt (20, 21) transmission between ball bearing mounted pulleys (150, 160, 170, 180) of the energy from several inclined barrels (15, 16, 17, 18) joined by a torque divider (40) and charged by a mass (14) oscillating linearly between sprung stops. Includes INDEPENDENT CLAIMs for the use of toothed belts and for the manufacture of the belts by moulding synthetic material on a metal substrate and for partial visibility of the belts through the watch face. Includes an INDEPENDENT CLAIM for a regulator that can be set before insertion in the watch. #CMT#USE : #/CMT# Watch movement for large watches with non planar shape. #CMT#ADVANTAGE : #/CMT# The use of pulleys avoids some disadvantages of gears including the ability to have inclined barrel axes without expensive conical gears and so use watches that do not have flat parallel faces. The inclined barrels allow a curved shape which can be useful for large watches. Avoids the need to set shaft axes relative to each other with great precision. Does not require lubrication or metal gear teeth. Can transmit movement across the mechanism without intermediate gears. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing is a perspective view of the mechanism. 14 : Linearly oscillating mass 15, 16, 17, 18 : Inclined barrels 20, 21 : Belts 30, 32 : Eccentric tensioners 150, 160, 170, 180 : Pulleys.</p> |
