Description

Safety clutches to prevent breakage of the prly1 here) 5 if it is modified ogioiapha ppmsmskmpshnli nla lomuipphgch organizatyu, naiii) shear hlie, cyxapeii, etc., mn jo frpkg | Ea ln are used breaking orgN) 1, which is impossible to exactly oiri; (ellt nonelichngu of the torque limit of the safety projectile and depends on the quality of its material, and on the duration of the prefuser. the inaccuracy of determining the predggnogo moment, depended on the gfs on the coefficient, its training for the borrowing of one part and their mutual pressure.

The proposed safety clutch is made in the form of a plapetartuged reducer, in which the screw1; atot11; T1g mommett transmitted by the reactionTininoMy;) lem, e (yyiaunoiiciiniiJaeTcn) with an emphasis, loaded HjiOT iB; iotsom.

The radius of the flywheel and the gearbox teeth) 7; (; forests of the first water stream are transmitted to a 1 drive shaft 2, a coupling, and an H.

Shaft 2, on which the swapodio vrap1, ats drive gear 1, is equipped with one or several cranks 5, u: f of which each bears the planetarp gear 6, comboil: uuus with one the sides with the solar side 4, and on the other side with the gear ring gear 1.

When the wheel 1 rotates on the shaft 2 the shetern 6 rolls along the pipodvI / k1UY gear 4. The moment transmitted at the dead shaft 3, ypa BiioiieniHisa occurs with the rest of the stop 7 through the significant transfer by the load 8.

Hn KHiiit the end of the unor 7 is located between two levers 9 p 10, which are co-spliced by two toothed sectors 11. The lever 9 is connected by a 12 niapnnpiio pull to the crank lever 13, which rotates the axle pivot 14. On the shoulder of the lever 13 is placed an adjustable load 8,

On fpg. 1 point display with a lever arm with weight 8 when it is thrust resistant 7 under the action of the coupling transmitted by the clutch, exceeding its limit defined by the size and weight of load 8. When deflected, load lever 13 loads 8, passed through the vertical, shown 110 points, the position remains in it and the levers 9 and 10 do not stop the rotation of the wire 7 with the shaft 3 and the solar gay sensor 4. After this, the Jester 6 can rotate on its axis, le turning the curve ) 5, and wrap: Eee from J5edy tsego cogwheel 1 to Vedo. the shaft is not transmitted.

Thanks to the design of the levers 9 and 10, the clutch works independently of the direction of the traveling and driving organs of the clutch.

Ifpiiinunt, n the proposed coupling limit can be ns yuzlovap d.ch 3ajnTCi velpchi) and, 1 transmitted mo memit (Fig. 2).

The trunnion 15 on the DTOII php-gur corresponds to the trunnion 14 in FIG. I. Cargo 16 nodvengen on vertical 17, which is connected with ukreilenpa at the end of the nidro.ippo T1odvp} 1t1 gop 19. 19. Tarah 19 is attached to the karandati 20, which is in contact with the paper tape on the drum 21, driven in real time mehantgzlgom. When the deviation of the dialer 7 (Fig. 1), causing the rotation of the 15 of the payload, the load 16 (php. 2) deviates to the left and the gate 18 will move 19 of 19 with a carat 20, which will produce the corresponding record on the drum 21.

Subject invention

The fuse clutch for automatism of the overload transfer switch, characterized in that it is made in the form of a planetary gearbox, in which the rotating shaft of the rm of the reactive element is equilibrated with a wior, counterbalance.
