Description
Technical field
The present invention relates to be used for the dampening arrangement of the balance pivot of timepiece movement.
The present invention relates more specifically to be used for timepiece movement, dampening arrangement in particular for balance pivot, this dampening arrangement comprises collet, this collet by spring remain in (shape) that be arranged on the fixing supporting member complementary bearing seat, and the jewel that forms end stone (endstone) is installed, wherein, this spring forms by being fixed into the bonding jumper of giving prominence to above supporting member, this bonding jumper extends in the sagittal plane of pivot, and form the arm that comprises stiff end and recline end, end abuts in vertically on the end stone collet is remained in the bearing seat of collet vertically thereby this reclines.
Background technology
In CH patent No.237 999, disclose and show such dampening arrangement especially.In this patent, the stiff end of spring arm is away from end stone, and must between the center section between end and the stiff end of reclining of the end face of batten and arm a space be set, so that allow this arm flexibly crooked around horizontal substantially axis.
Because bigger at the arm of force that reclines between end and the stiff end, be difficult to accurately to control by spring being applied to answer intensity of force on the end stone, this has increased difficulty for the such dampening arrangement of development.In addition, the answer intensity of force of spring has certain limitation, when hope changes the characteristic of restoring force, just must integrally change on whole length spring arm.
Summary of the invention
The objective of the invention is to overcome these defectives.
Therefore, the present invention proposes a kind of dampening arrangement of the above-mentioned type, it is characterized in that, from stiff end, thereby this arm comprises that overall is that straight line and the part radially that is parallel to pivotal axis, the elastic part that is shaped as annular section and overall the extension along the diametric(al) that is basically perpendicular to straight line portion form the part that reclines that reclines and hold.
The present invention also proposes a kind of timepiece movement that this device is installed.
Description of drawings
By reading with reference to the accompanying drawings and, can more being clear that other features and advantages of the present invention, in the accompanying drawings by the detailed description that non-limiting example provides:
-Fig. 1 is the schematically illustrated axial section that is equipped with according to the part of the timepiece movement of the dampening arrangement of instruction of the present invention;
-Fig. 2 is the vertical view of the dampening arrangement of schematically illustrated Fig. 1.
Embodiment
Fig. 1 and 2 illustrates the timepiece movement 10 of the dampening arrangement 12 that the pivot that is used for escapement 16 14 that instruction according to the present invention makes is installed partly.
Timepiece movement is fixed with the machine plate 18 of the supporting member 20 of escapement 16 on 10 particularly including its, and this supporting member will be called as batten or clamping plate 20, be known as " balance cock " sometimes.Escapement 16 can be installed between batten 20 and the machine plate 18 around its axis A1 rotatably by bottom pivot 15 and top pivot 14.
Batten 20 comprises crosswise fixed plate 22 on the end face 24 that is threaded in machine plate 18 and the apart transverse support plates 26 that projects upwards from fixed head 22, and this apart transverse support plates 26 limits axial space as the passage of escapement 16 with the end face 24 of machine plate 18.
Support plate 26 comprises the bearing seat 28 with hole 30, and this bearing seat is admitted the collet 32 of the bearing of the top pivot 14 that forms escapement 16.Bearing seat 28 is arranged in the intermediate member 34 that is fixed on the support plate 26.
Bearing seat 28 forms step vertically and comprises for example recessed shoulder of truncation, and this shoulder protrudes surface complementarity with the truncation that forms on the circumferential wall of collet 32.
Collet 32 is equipped with the jewel 36 of bottom of which has holes and forms the top jewel of end stone 38, and wherein bottom jewel 36 is used to admit the head portion of the top pivot 14 of escapement 16.Here end stone 38 comprises raised surface 40 a little.
Collet 32 flexibly remains in the bearing seat 28 by spring 42.Spring 42 is formed by flat bonding jumper, and this bonding jumper is fixed to above the support plate 26 of batten 20 outstanding.Spring 42 extends in the sagittal plane of pivot 14, and forms the arm 42 that comprises stiff end 44 and recline end 46.Thereby the end 46 that reclines abuts on the convex surfaces 40 of end stone 38 equilibrium position that collet 32 is remained on vertically in the bearing seat 28 vertically.
According to instruction of the present invention, from stiff end 44, thereby arm 42 comprises that overall is the part 48 of the radial direction of straight line and the axis A1 that is parallel to pivot 14, the part 46 that reclines that is shaped as the elastic part of annular section 50 and forms the end 46 that reclines generally along the diametric(al) extension that is basically perpendicular to straight line portion 48.
The state work down that annular section 50 reverses around the axis that is parallel to straight line portion 48 on the whole, this guarantees to control best the restoring force that is applied on the collet 32.For example can under the situation that does not change axial width, optimize this restoring force by the suitable radial thickness of selecting annular section 50.
According to an advantageous embodiment, the part that reclines 46 is extended and is comprised hole 52 from an end of annular section 50, this hole with the axis A1 of pivot 14 coaxial and in the sagittal plane, comprise crooked circumferential edge 54, this circumferential edge 54 limit at least three contact with the convex surfaces 40 of end stone 38 recline a little 56.
Preferably, the part 46 that reclines is stretched out a tongue-like part 58 in a side relative with annular section 50 along diametric(al).
Annular section 50 is in the angular range extension of---for example about 270 spend---more than or equal to 180 degree substantially.
Advantageously, straight line portion 48 totally extends along the tangential direction of the neighboring of end stone 38.
Annular section 50 with respect to straight line portion 48 in a side upper edge lateral offset relative with pivot 14.
According to shown in embodiment, stiff end 44 is by forming totally forming for the radial plate of rectangle of right angle with straight line portion 48.
Preferably, the bottom radial surface 60 of straight line portion 48 abuts on the relative radial surface of batten 20 vertically.This set guarantees that thereby arm 42 suitably abuts on the batten 20 annular section 50 and works best under twisting states.
According to the embodiment that illustrated just now, dampening arrangement 12 according to the present invention is arranged on batten 20 1 sides.According to a kind of alternative embodiment (not shown),, dampening arrangement 12 is associated with bottom pivot 15 thereby can being arranged on machine plate 18 1 sides.
