2 2 FLEXIBLE COUPLINGS Orpex copings are ses compensation copings everywhere where an absotey reiabe torqe transfer is reqired. Orpex copings cover with their types a wide range of ses. With a tota of 26 sizes, copings are avaiabe for torqes from 200 to,300,000 Nm. The coping haves of the type consist of grey cast iron. With the type of stee it is possibe to se the coping with high speeds. With the convex eastic eements which can be moved in the hoes the bffers it is possibe to compensate for the shaft offsets in agar, radia anxia direction. Orpex copings damp torqe impacts and offer the possibiity of shifting critica speeds. Orpex copings are fai-safe p to the fractre moment of the meta parts, which is a mtipe of the permissibe impact moment, and ths offers the greatest possibe operationa safety. Orpex copings can be sed for both directions of rotation anre aso sitabe for reversing operation. The bffers can be expected to have a ong ife with correct design of the coping and correct aignment of the assemby. Orpex copings can aso be adapted in many ways to specia reqirement profies. A arge nmber TYPE > > of appications aready creatend triere avaiabe for this. Or Projects Department wod be peased to advise yo. Orpex copings have proven themseves over decades in a areas of mechanica engineering, especiay in the case of heavy-dty drives, as an absotey reiabe and practicay maintenance-free machine eement.

FLEXIBLE COUPLINGS 3 FUNCTIONING The positive torqe transfer is achieved by means of eastic eements sbjected excsivey to pressre which then deform easticay nder compression.

TECHNICAL DETAILS > Perfect transfer of the torqe and trobe-free fnctioning are ony garanteed when origina Orpex bffers are sed.

> Orpex copings are normay fitted with a feather key groove according to DIN 6885 part and set screw. Design with wedge groove according to DIN 6886, tightening from inside of hb, is possibe.

3 FLEXIBLE COUPLINGS 3 FUNCTIONING The positive torqe transfer is achieved by means of eastic eements sbjected excsivey to pressre which then deform easticay nder compression. The progressive spring characteristic and the exceent damping properties of the bffers conteract the dangeros bid-p of any rotary vibrations that occr. TECHNICAL DETAILS > Perfect transfer of the torqe and trobe-free fnctioning are ony garanteed when origina Orpex bffers are sed. > The arrangement of the coping parts of the types and on the shaft ends to be connected is discretionary. Both horizonta and vertica instaation is possibe. > Orpex copings are normay fitted with a feather key groove according to DIN 6885 part and set screw. Design with wedge groove according to DIN 6886, tightening from inside of hb, is possibe. Care mst be taken here to ensre that the maxi aowabe hoes ony amont to 60 % of the maxi aowabe hoes with key feather groove according to DIN 6885 part. Torsion spring strips and torsiona anges The optimised rond convex form of the bffers favors the compensatory fnction where angar or radia offsets are present and minimises restoring forces. The grond bots are fastened with no pay by means of a conica seat. This effectivey prevents any possibe widening of the ocating hoe and the deveopment of frictiona corrosion. The convex bffers of the Orpex copings can be monted by pgging in. It is possibe to repace the bots and bffers withot any axia dispacement of the motor or the machines. Uncoped machines can be dismanted radiay. The bffers can be set ambient temperatres of 30 C to +80 C. They are resistant by eectrica condction against oi and many other media. > Rotating parts mst be secred by the prchaser to prevent nintentiona contact. When prodcts are sppied to other contries the safety regations appying there mst be observed. > The shaft ends to be connected mst be stored iediatey in front of and behind the coping. > We are at yor service for design to DIN 740 part 2 and for vibration cacations. Vibration cacations can aso be ordered from Engineering Service. > With respect to the instaation and coissioning of Orpex copings the instaation and operating instrctions mst be observed.

Orpex copings absorb position deviations in the machines to be connected. When aignment is being performed the radia anngar offset of the shaft ends mst be kept as sma as possibe, since this wi engthen the service ife of the bffers nder otherwise identica operating conditions. The coping mst be assembenigned in accordance with or operating instrctions. The offset figres given as aowabe in the tabe are intended for genera gidance. PERMITTED SHAFT MISALIGNMENT The permitted shaft misaignment depends on the operating speed. As the speed increases, ower shaft misaignment vaes are permitted.
