Abstract
The invention discloses a sliding type universal shaft of a hairspring rolling mill, which comprises linkage balls at two ends, wherein a ball type rolling shaft and an inner spline type outer sleeve are connected between the linkage balls. The linkage ball body comprises a first linkage ball body and a second linkage ball body; the first connecting shaft sleeve is arranged in a spherical groove of the first linkage sphere, the spline shaft sleeve is arranged in another spherical groove of the first linkage sphere, the ball is arranged in a ball hole of the ball rolling shaft, the ball rolling shaft and the ball are simultaneously arranged in an inner hole of the spline shaft sleeve, the other end of the ball rolling shaft is arranged in a spherical groove of the second linkage sphere, and the second connecting shaft sleeve is arranged in another spherical groove of the second linkage sphere. The rolling mill has the advantages that the spherical crosshead shoes at the two ends and the ball rolling shaft in the middle can simultaneously slide in the spline housing, and the friction is reduced by the spherical sliding effect, so that the angular and axial deviations from the connecting shaft can be automatically eliminated, the running hardbanding is eliminated, the rotating gap is reduced, and the stable running of the rolling mill is realized.
Description
Technical field
The present invention relates to a kind of universal shafts；More particularly to a kind of universal sliding axis of balance spring milling train.
Background technique
High-quality balance spring is the elastic element of high-end watch machine core, and quality has the timing accuracy of wrist-watch very heavy
The influence wanted, balance spring and balance wheel cooperatively form a vibration period with definite value and stable, and this vibration period is
Wrist-watch time base, therefore accuracy when walking and stability all have direct relation with this vibration period, and influence vibration
One of critically important factor of mechanical periodicity is exactly the geometric dimension of balance spring, and the high precision rolling of balance spring is watch hairspring production
In critically important technical process, the run stability of balance spring rolling press largely decides the quality of balance spring, with
The continuous upgrading of product specification has a higher requirement to the raising of each parts precision of rolling equipment, balance spring during the rolling process, shadow
There are many factor for ringing Product Precision.Fig. 1 is the floor map of existing universal shaft coupling device；Universal shaft coupling device setting is in driving gear
In the middle part of case and roll support axis, the two is connected.Used at present be universal shaft coupling device is cross pin shaft and rectangular fixture block formula knot
Structure, the structure are related to flexibility ratio, angular torque and fixture block friction of axis knot etc., avoid rhabdion phenomenon from needing to reach flexibility ratio
Amplify each portion gap, but also will appear gyration aperture disadvantage bigger than normal, in addition, due to poor (the driving gearbox output shaft of axle position
With the center of roll support axis away from), bring is angularly hardened phenomenon with the rotation that is easy to produce of axial deviation, and above-mentioned factor can
Radial force wild effect of the roll in rotation is generated, cyclic fluctuation is generated, influences the stability operating of milling train.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of balance spring milling trains that milling train run stability is high.
The technical scheme adopted by the invention is that a kind of universal sliding axis of balance spring milling train, including, the linkage ball at both ends
Body is connected with bead type roller bearing and internal spline formula housing among through transport sphere.
The linkage sphere includes the first linkage sphere and the second linkage sphere；First connecting bushing is mounted on the first linkage
In the rounded channels of sphere, hub splines is mounted in another rounded channels of the first linkage sphere, and ball is mounted on ball roller bearing
In ball, the ball roller bearing is mounted in the inner hole of hub splines simultaneously together with ball, the ball roller bearing other end installation
In the rounded channels of the second linkage sphere, the second connecting bushing is mounted in another rounded channels of the second linkage sphere.
The linkage sphere is spherical cross sliding block.
The invention has the advantages that since both ends spherical cross sliding block and intermediate ball roller bearing can be simultaneously in spline housing
Sliding, spherical surface sliding effect reduce friction, therefore can eliminate automatically from angular, the axial deviation with connecting shaft, eliminate fortune
Turn scleroma and reduce gyration aperture, to realize the steady running of milling train.

Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description:
As shown in Fig. 2 a to Fig. 3, universal sliding axis of the present invention is fixedly mounted on the both ends of milling train gear-box and roll stand, shape
At the coupling part of the two.Universal sliding axis includes the linkage sphere at both ends, is connected with bead type roller bearing among through transport sphere
With internal spline formula housing, make in operating that bead type roller bearing can be free to slide in spline housing, plays automatic eliminate and come from and even
Angular, the axial deviation of spindle, the freedom degree of joint play the role of eliminating rotation scleroma and reduce gyration aperture；The linkage
Sphere is spherical cross sliding block, and the spherical surface sliding effect of spherical cross sliding block reduces friction, eliminates due to tilting tolerance band
The rotation scleroma phenomenon come.
The linkage sphere includes the first linkage sphere 2 and the second linkage sphere 6；First connecting bushing 1 is mounted on first
It links in the rounded channels of sphere 2, hub splines 3 is mounted in another rounded channels of the first linkage sphere 2, and ball 4 is mounted on ball
In the ball of pearl roller bearing 5, the ball roller bearing 5 is mounted in the inner hole of hub splines 3 simultaneously together with ball 4, the ball rolling
5 other end of axis is mounted in the rounded channels of the second linkage sphere 6, and the second connecting bushing 7 is mounted on the another of the second linkage sphere 6
In rounded channels.
The three-in-one structure of universal shaft of the present invention reach joint coordinate well, reduce friction, improve it is axial, through to and
Angular freedom degree effect, to reach the purpose of steady raising roll torque and stabilization roll radial force.
It is worth noting that protection scope of the present invention is not limited to above-mentioned specific example mode, it is according to the present invention
Basic fundamental design, it is also possible to which the purpose of the present invention may be implemented in basically same structure, as long as those of ordinary skill in the art
Creative work is needed not move through, the embodiment that can be associated all belongs to the scope of protection of the present invention.
