Description

The invention relates to the field of mechanical engineering, in particular to the machine tool industry.

A cordless coupling is known, which comprises a hollow shaft, inside which is placed a razor | Pore; ny shchtok, which interacts with the sleeve jv aMH through, sch1rI K1 pru} {yny i.

Known: otsapl n coupling, /. soda (rzhascha leading body and slave-elements, installed on the hollow shaft with radial holes, in which the p-displacement of the balls, 1 vzaglmodeystuvu) with rmspyurnym mTQiKOM, installed ui “u | rival 1 and has thickening. c. avnymi mosi, and shch | ri1ki. podzhaty to flat springs with 1 cut. at about the other end, closed on the shaft of another “onts 2.

The disadvantages of an uncoupled coupling are high, low; M | Icheak load.a l / hr switch-on, arising during the impact HE1CT) LO (In iKopinyca with radial holes, extracted from the radial holes p, and the values are: 1 rod, as a result, the couplings have a low iqpOiK, and a low. reliability.

With the Purpose of Increasing C (service life and reliability, the proposed clutch is equipped with crackers, mounted, with charts, and an elastic element that presses the crackers to the shaft. .and rotation of the muff. teeth ,, sho-dprugi.; not "" to the middle of the grooves... they yus.

In the pentre of each 1paz there are teeth 4 installed using flat springs 3 that have 1znes; the key is pivotally hinged into radial grooves of the housing / coupler . The springs 3 keep teeth 4 in grooves 2 and excite (they luster “about the body”: neither with the tongues 5) to their original position

25 due to the fixing in the body of the teeth 4 perpendicular to their axis of symmetry. The ends of the spring 5 are mounted in the legs of the uprights 6 with the possibility of movement. The balls 5 are located in the radial holes 7 of the polo of the 30th shaft 8.
