Sub-assembly for movement of timepiece i.e. watch, has spacer for guiding movable element pivotally mounted on plate, and drive unit attached to movable element that slides relative to spacer with frolic

摘要

#CMT# #/CMT# The sub-assembly (10) has a spacer (2) for guiding a movable element (3) pivotally mounted on a plate (1). A drive unit (5) is attached to the movable element that slides relative to the spacer with a frolic (E) axially fixed between a collar (31) of the movable element and a front end face (24) of the spacer, and between an abutment surface (51) of the drive unit and a rear end face (25) of the spacer. The movable element includes a flange (31). A machining unit (37) cooperates with a complementary machining unit (61) having a display element (6) for fixing the movable element. #CMT# : #/CMT# Independent claims are also included for the following: (1) a timepiece movement (2) a timepiece (3) a method for assembly of the sub-assembly on a plate. #CMT#USE : #/CMT# Sub-assembly for a movement of a timepiece (all claimed) i.e. watch. #CMT#ADVANTAGE : #/CMT# The sub-assembly allows optimal transmission of permissible axial force to the plate or a support element for receiving a driven component in a reliable and accurate manner while avoiding the risk of permanent deformation of a wheel bridge. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a sub-assembly including a movable element mounted via a spacer.
