Description

(54) ELASTIC PROTECTION CENTERS COOLED COUPLING

: NAL

Thereby, the latter are formed by longitudinal holes made in a thick-walled glass and connected on the one hand with outlet channels and on the other hand with an annular cavity, and the outlet channels are formed by longitudinal grooves made outwardly: the surfaces of thick-walled glasses and the inner surface of a thin-walled glass, and connected to the cavity of the body of the holes made in a thin-walled glass.

In addition, longitudinal ribs are made on the inner surface of the body.

FIG. 1 shows a coupling, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The centrifugally resilient-cooled is cooled and contains a carrier made in the form of a thick-walled cup covered by a thin-walled glass 1, fixed to two disks 3 by the ends, one of which is rigidly connected with a driving shaft 4, and the second is loosely mounted on the driven shaft 5. Flexible connections 6 covers the pulley 7, which is rigidly connected to the home shaft. The ends of the flexible connections are fixed to the rollers 8, which are freely mounted on the fingers 9. The rollers are placed in the cavity 10 of the thick-walled glass. In a thick-walled glass 2, a system of ventilation ducts is made, consisting of outlet ducts 11 formed by longitudinal grooves on a thick-walled glass and the inner surface of a thin-walled glass that covers the thick wall glass and has radial holes 12 for air release, as well as longitudinal holes 13, exit one end into the radial annular bore 14, made in the middle of the thick-walled glass, and the other end into the gaps 15 between the ends of the thick-walled glass and the disks 3, closing the thick-walled the first ends of the glass. Two impellers 10, which are located on both sides of the pulley and serve to counter-pump cooling air in an annular gap 16 between the pulley 7 and the thick-walled glass 2, are rigidly connected to the drive shaft 4.

When the drive shaft 4 rotates, the flaps 10 force air into the gap 16 on both sides. The air cools the friction surface and, passing through the system of ventilation channels, gives off some heat to the thick-walled glass 2. After it leaves the radial holes 12 from the carrier, it passes to the intercostal space housing 17 where it is further cooled. The cooled air is again pumped by the impellers into Zzzr 16, and the cycle is repeated.

 The use of the invention will expand the scope of application of elastic-inertial safety cooled sleeves with flexible couplings to machine units operating in an explosive environment under conditions of limited space for accommodating the coupling.
