MALLISTO
GC GEAR COUPLINGS The gear coupling is a torsionally rigid coupling, which can transmit a relatively high torque when compared to its physical size. The crowned gearing can compensate for small angular and radial misalignments between the shafts, and even long axial strokes can be achieved by altering the gearing length. The gear coupling is thus considered a flexible coupling. Torque is typically transmitted from the shaft to the coupling by a keyway and a fitted bore joint, and from the hub to the sleeve by the gearing. Torque is then transferred between the two coupling halves and thus from the driving machine to the driven unit by a flange joint. The gear coupling has a very long lifespan, when correctly dimensioned, and it is easy to tailor to fit almost any drive. MFG's GC gear coupling line-up covers shaft sizes 20-1000 mm, and torques up to 16 000 000 Nm. The smaller sizes are made in Finland, and the larger sizes from GC-400 and up are made in Germany. Modern and flexible manufacturing methods make it possible for MFG to supply customized solutions with a quick delivery time. Special materials and heat treatments are available on request.

DPC METAL DISCPACK COUPLINGS The metal discpack coupling is a torsionally rigid and backlash-free shaft coupling, which can compensate for relatively large angular and radial misalignments between the connected shafts. The all-metal construction is not susceptible to heat, and is maintenance free, so the coupling is especially well suited for drives where traditional rubber element couplings can not be used due to heat or high drive torque. A correctly installed and dimensioned discpack coupling's lifetime is at least as long as that of the connected machines, and it requires no maintenance apart from visual inspection. The discpack can be inspected when the machines are running with a strobe light. The MFG DPC metal discpack coupling line-up covers shaft diameters 20-135 mm, but larger sizes are available on request. The DPCC version allows for a short distance between shaft ends (DBSE), and is equipped with a split spacer so that the machines do not need to be moved when changing the discpacks. The DPCC may also be used to replace a gear coupling, if maintenance free operation is desired.

KKT CLAMP COUPLINGS A clamp coupling is a simple, rigid coupling for joining to machines together, or to be used as a shaft extension. The most common applications are overhead cranes and different drives in the saw mill industry, and also vertical mixers. The DIN standard clamp coupling is made of cast iron and is relatively large, where as the MFG clamp coupling is made of steel. This steel coupling is backlash free and much smaller than the DIN standard coupling, so it is especially well suited for drives with space limitations or high rotation speeds. The coupling can be installed and disassembled without moving the machinery, and is maintenance free. The MFG clamp coupling line-up covers shaft sizes 30-150mm, but larger models are available on request. Different materials, such as stainless steel, are also available. Vertical drives can be equipped with the KKT3, which is fitted with a limiter plate inside the coupling.

TK TAPPIKYTKIMET Tappikytkin on hyvin tunnettu ja hyväksi todettu, erittäin varmatoiminen akselikytkin, joka sallii verrattain suuria poikkeamia akseleiden välillä, sekä tasoittaa vääntövärähtelyä. Erityisesti kaivosteollisuudessa suositun tappikytkimen kestoikä on yleensä vähintään yhtä pitkä kuin liitettyjen koneiden, eikä se vaadi huoltoa silmämääräisiä tarkastuksia lukuun ottamatta. Joustoelementit ovat vaihdettavissa purkamatta kytkintä, ja niiden materiaalivalinnalla voidaan vaikuttaa kytkimelle sallittuun käyttölämpötilaan. MFG:n tappikytkinmallisto kattaa koot aina 1000mm halkaisijaan saakka, ja helposti räätälöitävä rakenne mahdollistaa myös erikoisversiot esimerkiksi koeajopaikkojen tarpeisiin. Tappikytkin on yleisin SPC-murtosokkakytkimeen yhdistetty kytkinmalli. TKR malli on varustettu aksiaalisliikkeen rajoituksella, jotta sitä voidaan käyttää liukulaakeroitujen sähkömoottoreiden kanssa.

SPC SHEAR PIN COUPLINGS The SPC coupling is actually a part of a coupling, which can be integrated with another type of coupling, such as a gear coupling. The purpose of the shear pin coupling is to quickly disengage the driving and driven machine from one another, in case of a sudden problem such as a short circuit. The shear pin can be customized to provide different shearing torques, which should always be some what higher than the highest maximum operating torque of the drive during start-up, for example. The most common application for the SPC shear pin coupling are different test benches, where unexpected disturbances are common. The SPC coupling line-up covers shear torques of 5-140 knm, but higher torques are available on request. The SPC unit is comprised of MFG's standardized parts and bearings, so that the same spare parts and pins can be used in different couplings.
