<p>#CMT# #/CMT# The mobile i.e. driving toothed wheel (1), has rigid tooth (4, 5) distributed into groups of consecutive tooth. The rigid tooth are formed with respective engaging flanks (10, 11) that are facing each other to permit the displacement of another clearance compensation mobile i.e. driving toothed pinion (2), in two directions. Spring plates (16) are intercalated between the groups, in spaces not receiving rigid tooth (3) of the later mobile. The spring plates extend beyond a head circle (Ca) of the tooth of the former mobile to cooperate with the later mobile. #CMT#USE : #/CMT# Clearance compensation mobile i.e. driving toothed wheel, for forming a gear i.e. gear with external tooth, with another clearance compensation mobile i.e. driving toothed pinion, in a time piece (all claimed) i.e. wrist watch. Can also be used for forming a gear with internal tooth. #CMT#ADVANTAGE : #/CMT# The rigid tooth of the wheel are formed with the engaging flanks that are facing each other to permit the displacement of the pinion in two directions, thus allowing the gear to work in two directions and have equal and better yield in the two directions. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial plan view of a gear. Ca : Head circle 1 : Driving toothed wheel 2 : Driving toothed pinion 3-5 : Rigid tooth 10, 11 : Engaging flanks 16 : Spring plates.</p> |
