发明名称 Damping rod receiving mechanism for spiral beam of time piece, has endstone whose surface is opposite to end surface of rod and makes contact with rod end surface made of curved surface protruding outside in convex manner
摘要 #CMT# #/CMT# The mechanism (1) has a damping plate (30) housing and supporting a frame (20) of a stone-cons pivot (17), and including a commitment part (36). A support fixation part (37) includes an external circumference supported by the commitment part, and an internal circumference pushing elastically an endstone (10) against the frame to hold the endstone. A surface of the endstone is opposite to a spherical end surface (12) of a rod supported by the mechanism, and makes contact with the rod end surface that is made of a curved surface protruding outside in a convex manner. #CMT# : #/CMT# The endstone is made of sphere. An independent claim is also included for a spiral beam. #CMT#USE : #/CMT# Damping rod receiving mechanism for a spiral beam of a time piece (all claimed). #CMT#ADVANTAGE : #/CMT# The surface of the endstone is opposite to the spherical end surface of the rod supported by the mechanism, and makes contact with the end surface that is made of the curved surface protruding outside in a convex manner, so that variation in operation of the spiral beam due to variation in a support state of a beam axis can be minimized, and a variation in the operation of the beam due to difference in attitude such as between top and bottom attitudes, and minimized while making the dimensions of the endstone in a highly precise manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a damping rod receiving mechanism. 1 : Damping rod receiving mechanism 10 : Endstone 12 : Spherical end surface 17 : Stone-cons pivot 20 : Frame 30 : Damping plate 36 : Commitment part 37 : Support fixation part.
