COUPLINGS TYPE MKO 2
MKO (lightweight compensating coupling) is a common industrial coupling, designed for widespread usage in machines and mechanisms for various purposes in all industries. It is characterized by simplicity of design and, respectively, minimum cost. The shape of the elastic element - "Ring".
In contrast to the standard all-metal couplings according to GOST 26455-96, the MKO coupling is structurally protected from mechanical sparking as well as from dangerous “overhang” of the removable middle part (spacer) in case of emergency destruction of the elastic element and at the same time it provides a short-term torque transmission (without saving compensating characteristics).
The standardized series of МКО couplings is coordinated in terms of torque and connecting dimensions with asynchronous electric motors for general industrial purposes..
As standard, the coupling is supplied with coupling halves “for boring” and for the typical distance between the ends of the shafts S , shown in the table. To order a coupling with a bore and keyways and (or) an individual distance S, you must fill in the questionnaire.

|Coupling nominal size||
Standard length of coupling half L, mm
|Coupling outer diameter D, mm||The minimum distance between the ends of the shafts Sme, mm||Bore diameter of half-couplings dmax, mm||Transmission unit weight||Weight of unbored coupling half standard, kg|
|At Sme, kg||+ΔS=10мм, kg|
*Transmission unit length S performed, starting from size Smin and more in steps ΔS = 10mm., other sizes depending on the distance between the shafts are available on request. Length of half couplings L may differ from the standard, subject to filling out the questionnaire. dimensions AT and t pockets for fastening the coupling half with a nut are provided upon request when filling out the questionnaire.
Note: To determine the mass of the coupling assembly, it is necessary to add the mass of the two coupling halves with the mass of the transmission unit.. If not specified, the size of the cylindrical bore of the half couplings is made with an accuracy of H7 and the keyways Js9 are made according to DIN standards 6885.
