Description

Elastic (ft

Yubrete Yeshv belongs to the country, in particular, to the facilities for transferring rotation from the main axis to the city of

(Efimer, from ezhuurodvshvgvpya to the pump or komsfeoooru at significant isirivlgoE1И5зх axis of installation of shaft or their unmaintainment.

It is known disk elastic, compensating glufga 1, for connecting shafts that are expansion with angular displacement, consisting of and driven by} 1u1ofts with flanges b / kzhtsu which {not mounted 1khbor of steel DISES. Boshi with nuts, the wheels hfkrepryakugsya chfes sffichvskie washers to the flanges.

The specified coupling requires special attention in the manufacture of disks, which affect the operation of the muffle Г | я1 in the manufacture of dasaks, it is necessary to accurately calculate their identity, select the material and heat treat. In overstatement of their thicknesses, the disks do not require excessive stiffness of the coupling that Eeyjpi leads to overload of bearings, or to increased flexibility of the coupling. Reduction of the drive drive leads to a quick destruction of the disks themselves. As for the zmichsky processing of the disks, it is necessary to have temperature conditions corresponding to the selected material.

The expansion joint is a compensated coupling 2, which can be angled with angular and radial displacement, sucked from the master and driven half couplings, between which there is a disc set, which is mounted on the flanges of the master and driven half couplings.

One of the great things about this mufga is the transmission of relatively small torques. Such increased complexity of manufacturing many spherical surfaces., As well as the complexity of the preparation of the discs themselves, as in the previously described coupling.

There is a large coupling 3, which contains two ostoyuyuhshnyh floor mzfgy, ramep eeshshy between them and an additional shaft and two pavovt psbkogo membranes with holes, which are connected in most cases with the same size and are completely unobstructed open; in the openings of the membranes and the shaNb with convex ends facing the end huvernoscopy of the membranes, the mutually inverted surfaces of which are made with an open-end gap in the form of a polymer composition and have mesh corrugations under a Е га ф ф по по по г.

Wherever this coupling is specified, its low manufacturability is due to the low coefficient of use of the membrane material. As a result, the coupling is relatively large. 1 Moreover, the specified coupling 1 for operation is preheated with cyclic hubs. As a result, the deformity membranes are sagging or tearing apart and need to be replaced, which makes it easier to complicate.

To eliminate the indicated drawbacks nocramisEia task is to create a cheaper elastic coupling with increased technolochism.

Dsh: solves the supply of the ECUZO1, and the coupling also, as well as the well-known, contains two coaxially mounted half-couplings, placed on top of them and packages of flexible membranes with holes that are connected to the base and connected to the coupling.

bases on smaller / diameter, and tops - on larger diameters. The base can still be performed in the arcs arched to the tops of the packet.

The indicated distinctive shchengs are associated with the technical peiyiibTaioM, aimeshu:

-packages of flexible membranes are made in the form of a three-pack. This makes it possible to increase the techno-simplicity of manufacturing by changing batch stamping with changing (changing the position of the workpiece. K | X) and, therefore, the rational rationalization of sheet or ribbon mvge | ial: hfi v uubke from several passets or special plates for packages;

-packages of flexible membranes are crisscrossed by shrinkage over a smaller diameter. Such a fastening ensured the transmission of great sensory moments. That is, in order to resize a large moment with a small diameter, it is necessary to pacqpe OTO4Hib the transmitted force and increase the number of iqpene Hbix elements, which is also a technical solution;

-the vertices of the packs of flimsy membranes are eFeshkna in larger diameter. Since the torsion moment is the same for both small and large diameters, and the shoulders are different, the package peaks are quite enough, the number of holes is less than that for oyuyvaniya;

- the base is made in a wad of arcs that are drawn to the top of the packet. This allows the elastic coupling to be made smaller in diameter and more compact in a flail.

The inventive coupling is illustrated by drawings.

In FIG. 1 shows b0 | ft with a shortened delivery rate.

W fig. Figure 2 shows a utfuga coupling with a bucket. The Ugfugaya contains two coaxially mounted sweat couplings 1, 2. They are equipped with a delivery unit 3, which can be of different lengths and shapes and packages 4 flexible membranes with openings underneath

ezhmeyaty 5, 6, sv5 I call 1 more tylumufty 1,2 with a shchkhggavka 3 through packages 4. Packages of 4 solid membranes are executed in all-time treugolshov. Closing the pacts evenly, with the base according to М1 more on the floor of the box with fastening elements 5, and the top - along the large diameter 1 with the fastening elements 6. In this case, the base of the packages is made in the form of zug, vogautyk to their vertices. In the event that the base is enviable on the teehaw, then the top is mounted on the coupling half (Fig. 2).

Utfuga coupling works speduoonm obrshom

The upper 1 (Fig. 1) transfers the moment to the spacer 3, through the fasteners 5 and the fixed bags 4 of flexible membranes 1 with a smaller diameter to noji / My Te 1. D |) Having seen the moment, the packages 4 transmit eix through 1 fepeye1kme1пъ1 b for the error 3. In this case, 1 are peppy & b are located in the top of the package 4, that is, with a large diameter. Gave a tough moment from location 3 is transmitted to the main floor / sleeve 2 through fasteners b, packages of 4 flexible membranes and fasteners 5.

In the same way, the flange coupling works (Fig. 2), when the torsional moment is transmitted to plate 3 through 4 flexible membranes, which are terminated with the baffle elements b on the drive psu couplings 1 with a larger diameter and the base igpeneaoEibiMH elements 5 on a smaller spacer 3 diameter. Dalge transmitted torque, load 3, through iqpeneiKHbe elements 6, but also 4 flexible membranes and {fixing elements 5, is transmitted to Beaois "floor coupling 2.

In this and in the other case; which requires the bending of the axis or misalignment of the installation of half-couplings, the four-membranes are assembled with four solid membranes, COMPLETE the role of the elastic elements, KOMneeciipyEOT mounting errors and mounting errors. So, for example, in the bench tests of uffugay 4f1a (Fig. 2), 72 hours worked with the previously specified axis curvature

the installation of the Lolum 3G |) and the revision of the clutch after the last, meg scolding, from the other fasteners to the package were in good condition, there were no tears and wires around their perimeter. Overshooting, both at the base and the top 1 peaks, also did not have HazQibmoB. Its membranes are not unfused. 1 In addition, the clutch is convenient for operation and repair; since the packages can be turned over, rearrangements from one package can be rearranged in a dock. Г |} and this1 by the number of plates in a packet, it is possible to control the magnitude of the transmitted torque, and the number of packets located on (guards and the diameter of the arrangement of the packets, it is possible to cover a larger range of transmitted torques, using the same type of size of elastic elements that determine the relative I will cheapen the last and the increased repairfigodostnost.

This new technology is new and very smart. OYEuIt is literally to improve the manufacturability and cost reduction of the well-known clutch Pb. The preparation of the claimed utfuga 1oofts is carried out on conventional machines and with a custom-made tool.
