M.snecTlii.i eccentric couplings, containing iJUie leading and driven coupling half, in the bores of which are installed eccentrics.

The proposed clutch is known to be different in that it is equipped with an adjustment mechanism, made in the form of two levers-weights mirrored relative to each other, HiapiiiipHO mounted on the end of a lead, and it has coupling, which is external and connected to one another with concentrated gear located in the lead DnA, equipped with a finger, the entrance UUIM in the groove provided in the eccentric of the leading coupling half, sharnnrno connected with nolzun, podngno mounted in the groove, B1 (filled in the eccentric of the driven numping. Also oh polzui biased to WEDO roy polhmufte.

Such a coupling provides a shock-free coupling and disengagement of the shafts at various rotational speeds.

FIG. 1 shows the proposed coupling, the total vnd; in fig. 2 - sections according to BB and B-B on. one; in fig. 3-tmd on the arrow .A. I fig. one,

The eccentric muffler consists of a lead muffle /, which is connected to the leading parts of a monoste source and a cylinder shaped cylinder with an ilar surface. An eccentricity e vnolneplo otver2

This is an area in which the eccentric 2 is centered, which is made integral with the tweeter, forming a connection with the sliding ram 3, with the submersible spring 4. semi. coupling coaxially installed in the leading on. Muff. Since the ngipa axis is controlled; its eccentric 2 is located at a distance from its center, it is the same when the disconnected coupling coincides with the common axis of the half couplings / and 6.

The coupling mechanism consists of two mirrored, one-handed lever mechanisms and consists of weights 7, one end of which is connected with the leading half-sheave / and detachable by means of a spring 8, a disk 9 and 10. The disk 9 is coaxially mounted in the drive floor of the clutch / and has a finger, which is located in the groove of the exeaire 2, from which it forms a rocker mechanism. Consequently, when turning the disk 9 and a certain angle, the angle is equal to the rotation of the eccentric 2 relative to the leading half muff /. Wings W allow the mobile connection of loads 7 to the disk 9.

In the drawings, the clutch is shown in the disconnected nozhozhenin. I unplug the spring 8 holding the weights 7, simultaneously serving as levers in such a position that the finger of the disk turns the eccentric so that

The eccentric thorn axis 2 is aligned with the axle of the driven coupling half 6. The slider 3, which is associated with the clearance of the eccentric 2, is located in the groove of the eccentric 5, allowing the driven coupling coupling 6 to freely rotate relative to the driving floor of coupling I.

Upon reaching a certain speed and leading half coupling I in the loads 7, a centrifugal force arises, sufficient to overcome the force of the spring 8, as a result of which the loads diverge. The higher the rotational speed of the Veduid, it has the numflts 1, the more the radius of the cargo is diverted (in Fig. 3, the working position of one cargo is shown on the basis of the line), and in this case 10, in which, by virtue of a mirror, each is located from t g, a pair of forces arises, turning a certain angle of the dns 9, and consequently, an eccentric 2. At the same time, the eccentric 5 rotates at a certain angle, and the sliding edge 3, moving in a groove, compresses the external 4. In this case, the axis of the ilsha eccentric 2 does not coincide with the axis of the coupling half 6. Te Eph relative rotation iolumuft pronzoydet only rec nerehode polzu1ga 3 through the upper dead point. The stroke of the slider 3 depends on the angle of rotation of the eccentric 2. The greater the angle of rotation of the eccentric 2, the greater the stroke of the slider, and the stronger the spring 4 is compressed, creating a force directed through the axis of the eccentric and and the axis of the eccentric 2; Since the axis of the eccentric 2 in this case does not coincide with the axis of half coupling 1 1 6, a cool moment arises in it. As a result of the non-transfer of the moment of inertial removal of loads through the spring 4, the clutch ensures good elastic-dynamic properties.
