#CMT# #/CMT# The mobile part (1) has a board (2) toothed at its periphery and defining a sprocket. A toothed pinion (4) is arranged coaxial to the sprocket. An additional pinion (8) is provided with two portions (11, 12) along an axial direction, where the portions are provided with teeth. One of the portions is provided in a central hole (6) of the sprocket. The teeth are truncated such that the other portion is provided in a central bore (7) of the toothed pinion to assemble the toothed pinion with the sprocket. A shoulder (14) is formed between the portions of the additional pinion. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a mobile part for a horological movement. #CMT#USE : #/CMT# Mobile part i.e. timer, for a horological movement of a timepiece (all claimed). #CMT#ADVANTAGE : #/CMT# The design of the mobile part permits recycling of the additional pinion to form a connection unit between the board and new pinion with a single level, thus reducing the manufacturing cost of the mobile part. The mobile part can be manufactured in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified side sectional view of a mobile part. 1 : Mobile part 2 : Toothed board 4 : Toothed pinion 6 : Central hole 7 : Central bore 8 : Additional pinion 11, 12 : Portions 14 : Shoulder. |
