Description

OcHOiBHofi is caused by noise in the watch mechanisms during their operation and is caused by the presence of mechanical clutches in the trigger mechanism of the clock, causing periodic impacts on the teeth of the ratchet wheel. In a number of cases of practice, it is necessary to achieve the standard operation of watch movements. In the device proposed according to the invention, the trigger mechanism operates on the magnetic magnetic engagement principle, due to which not only mediocre contact of the trigger parts in the arrangement is eliminated and it is possible to perform a great operation of the clock. The peculiarity of the proposed trigger mechanism is that the latter is made in the form of a rotating part made of magnetic material located in the field of a permanent magnet, between which pole ends of which is placed another part made of magnetic material associated with the master and swinging with it so that as a result of the unlikely HaMairiHH4HBaiHKH of these parts, the interaction between me and I wait for them, which determine the registration / lyration of the course.

FIG. Figures 1 and 2 show two variants of an exemplary embodiment of the proposed device.

Hollow iron drum J with fortified on letters: curved iron ribs 3 can rotate in the field of constant magnet 2 (one or more). The field is directed in such a way that the iron tip 4 of the tandem 5 placed between the pole tips has an explicit pole of the same sign. When swinging a tiller, this pole tends to remain closest to M on the outer face of rib 3 on drum 1. When a drum gear is applied to the axis of the drum through a corresponding gear, a rotating torque (a gear, a spring or an electric motor), the drum acquires a stepped motion By transferring to the tambour (when passing through the middle part of the n} t: -and) energy necessary to maintain normal fluctuations. This energy is transmitted by magnetic interaction, without causing mechanical friction and: without creating a shum.

FIG. The drum i has 12 curved ribs, which merge with the ends and form a non-concave (behind the 1C-curved) zigzag contour. From this sigil of this way, the rocking head of the LS head follows with its magnetized tip 5. If, for example, the period of natural oscillations is 2 seconds, then the drum turns at a speed of 1 rpm. in 2 seconds. At the same time, there is a gear transmission | 12:60 (1: 5); you get the axis of the second hand, giving 1 rpm, etc.

It should be noted that the shape of the edge is somewhat asymmetric to give the best result in the sense of completely eliminating noise, since. at the same time, the speed of the drum will be lower than (by the time it stops) more, nla;

To the right of the plate and to the left of the bitter, the pole lugs of the permanent magnet 2 are rigidly fixed. Thus, the core / can swing — in a vertical plane parallel to the axis of the plate, leaving unchanged.
