In case of space misalignment over different levels, but providing identical combinations (Z/Z or W/W) and identical angles, uniformity is guaranteed. For high speed transmissions, the equality of β1 and β2 angles should be checked, in order to limit the difference to 1° ¸ 1.5° max (n > 300 rpm). More important differences (2° ¸ 3°) may be accepted in case of slow speed transmissions only (n < 300 rpm). RESULTING ANGLE In case of misalignment over several levels, both the horizontal and the vertical angles should be taken into consideration to determine the angulation. βh = angle on the horizontal plane βv = angle on the vertical plane tg β1-2 = tg2 βv + tg2 βh CALCULATING THE MAXIMUM ANGLE In order to obtain a silent transmission, centrifugal forces in the central section shall not be allowed to rise over a given limit. Centrifugal forces depend on the moment of inertia of the central section of the universal shaft and on the product of the number of revolutions by the deflection angle. n = max number of revolution in operation β = max angulation See table 37 page 40. MAXIMUM SPEEDS In order to achieve silent and vibrationless operating conditions, make sure that the rotating speed is lower than the maximum permissible speed set as a critical bending limit as well as a dynamical limit mentioned earlier. For critical bending speed refer to table 36 page 39. For dynamical speed refer to table 37 page 40. LOADS ON THE BEARINGS While designing the size of a universal shaft, it is important to remember that certain operating conditions involve axial and radial forces. Such forces must be supported by the shaft bearings of the machines which are drivingly connected by means of the universal shafts. 34 - Axial Forces The axial forces occur during the length variations of the universal shaft under load. Such forces increase as the torque increases. Fa = Td ⋅ µ rm ⋅ cos β Fa = axial force Td = torque rm = average radius of the splined profile µ = friction coefficient. It depends on surface roughness and hardness. Tabulated values 0.11 ¸ 0.15 for steel against lubricated steel β = angulation - Radial Forces Torque transmission by means of a universal shaft causes bending moments to occur at the shafts, generating radial forces which are therefore proportional to the torque and the deflection angle. These forces are not constant: they vary periodically following a sinusoidal curve, twice every revolution of the universal shaft. ORGANI DI TRASMISSIONE SIZE SELECTION RATING CHARACTERISTICS OF UNIVERSAL SHAFTS SERVICE AND LIFE FACTORS MK TABLE 31 = Rating designed torque (kNm) It corresponds to the maximum allowable, static constant torque. Only unfrequent, minor load peaks are admitted. MDW = Alternating torque (kNm) It corresponds to the fatigue maximum limit torque for a shaft subject to alternating load σ min/σ max - 1 ¸ 0 (stress σD-1 per 2 ⋅ 106 cycles). MDSch = Pulsating torque (kNm) It corresponds to the fatigue maximum limit torque for a shaft subject to a pulsating load σ min/σ max 0 ¸ 1 (stress σD-1 per 2 ⋅ 106 cycles). Service factors SF Load type Constant torque CT With light shocks LS With medium shocks MS With high shocks HS With very high shocks VHS = Limit torque = 1.3 MK (kNm) It corresponds to the maximum static torque provided by the maximum permissible elastic limit, and it shall never be overcome. Such a stress level may only be reached just 5 times/h for 0.5 ¸ 1 sec. M H OPERATING PARAMETERS N = Maximum motor or brake absorbed power (kW). If absorbed power or calculating data are missing, consider the motor rated load multiplied by absorption percentage (0,75 ¸ 2,25) n = Rated rotation speed of universal shaft (rpm). Ks = Overload factor. Such factor, considering: inertia and connection times possible jammings - maximum short circuits - electric motor absorption, shall assess the existing ratio between the rating torque and the maximum or occasional torque. An indication of possible readings should be looked for within the 1.25 ¸ 10 range. For rolling mills the T.A.F. (Torque Amplification Factor) value should be considered (1,3 ¸ 2). Z = Distribution factor. Such factor is supposed to take into consideration the different torque distribution over several outputs controlled by just one generator. Some tabulated examples are provided, as follows: Two driven work roll stands = 0.5 ¸ 0.66 Three driven work roll stands = 0.66 ¸ 0.75 Roll flatteners = 0.75 ¸ 1 Feeding rolls =1 Pinch rolls = 0.5 ¸ 0.75 Rubber mixers = 0.5 ¸ 0.66 For single drives, always consider = 1 N ⋅ Z ⋅ 9.6 (kNm) n - Absorbed torque Td = - Maximum torque Tmax = Td ⋅ Ks (kNm) H 1.5 2 3 5 10 = On-going drive with low pickup torques and without reversals and/or throbs.

Calculation methods, illustrated below, are based on the specifications of ISO 281 standards. Usually, the average life of bearings is approx 4 times longer than the calculated theoretical life. When it comes to drives characterized by important torque and/or rotating speed variations, in order not to oversize the universal shaft, the average torque and/or the average speed should be used to calculate the bearing life. In case the deflection angle is smaller than 3°, as the bearing oscillations are not important, no life dynamic test will be required. Only the static condition shall be checked, which will be deemed properly verified if meeting the following requirements: 3 MULTI-CYLINDER COMBUSTION ENGINE TABLE 34 < MDW for alternating torque drives < MDSch for pulsating torque drives Tmax < MCS for t = 0,5 ¸ 1 sec.

A proper surface protection coat normally realizes protection against corrosion on the flange machined surfaces. Different anticorrosion treatments shall be required in the order. Bearings and length compensator are pre-lubricated. Lift horizontally, using suitable nylon ropes. If handling in a vertical plane, secure the shaft in order to prevent the splined parts from separating, before lifting. For longer storage it is necessary to check the surface conditions and eventually cover with a new protection film. 1.10 For long storage (exceeding three months) relubricate bearings and length compensator, before installation. 2) ASSEMBLY 2.1 Remove the universal shaft from the packaging and check its conservation state. 2.2 Before assembling, flanges and companion flanges must be thoroughly cleaned to guarantee a perfect contact between each surface. 2.3 Balance weights should never be removed. 2.4 Splined parts must never be disassembled, to avoid interchanging, with consequent misalignment and unbalance of the unit. 2.5 The universal shaft yokes must be aligned. Check the arrow markings. Transport and store in horizontal position. The lifting equipment have to be selected according to the weights shown in our drawings or in our catalogue. 2.6 In the companion flanges, the coaxial tolerance of centering and the perpendicular position must be in a restricted range. Do not hang or transport in vertical position. For vertical transport it is necessary to require a special safeguard to keep the parts together. 2.7 Heat the companion flanges uniformly (100¸150 °C) for key fitting and (300¸350 °C) for shrink fitting before assembling onto the shafts. Wait for the complete cooling of companion flanges, before assembling the universal flanges. Ask for MAINA specification PFB 1202 (in case of shrink fitting) and PFB 1100 (in case of key fitting). 2.8 The companion flanges must be firmly fix and centered onto the shaft. Check that: - no backlash is present, - no end float is present, - keys or splined shafts have no clearance on their flanks. 1.6 Packings must be able to avoid any impact to the universal shafts and must protect them from any environmental event and from humidity and condensate. 1.7 Store preferably on suitable wooden frames. Avoid any kind of impact when handling and storing. Shocks and impacts, during transport and storage, could damage bearings, splined parts and their protective caps. 1.8 For long period of storage, machined parts should be protected against corrosion. 45 ORGANI DI TRASMISSIONE INSTALLATION, MAINTENANCE AND LUBRICATION 2.9 Check that the dimensions between shaft ends (minimum and maximum distances) are in accordance to MAINA drawings. NOTE: When installing fix length universal shafts, one of the units must be free to move, to compensate slight length variation, due to manufacturing tolerances or temperature changes. 3.2 - FIRST YEAR Every 200¸350 hours of actual operation time. - AFTER FIRST YEAR For normal applications every 2000¸3000 hours or every six months. For heavy duty applications every 500¸1000 hours or every two or three months. The intervals depend on: frequency of impacts, level of load, environmental conditions, rotating speed, reversing operation, operating angle, seal condition, frequency of shaft movements, length of stroke, movements under/no load. Particularly unfavourable working conditions may require shorter grease intervals. 2.10 WHEREVER PEOPLE OR MATERIAL COULD BE ENDANGERED BY OPERATING UNIVERSAL SHAFTS, SAFETY DEVICES MUST BE PROVIDED BY THE USER, FOLLOW APPLICABLE SAFETY CODES AND REGULATIONS. 2.11 Before fitting the joint flanges, their surfaces have to be accurately cleaned. They must be free from grease, coat or rust. 2.12 Complete flange bolting sets are available on request. MAINA normally provide: 3.3 - hexagon or cylindrical headed bolts (in accordance to DIN 931 - 12.9 or 10.9) 3.4 NOTE: a) When regreasing, use a compatible lubricant. b) Grease nipples must be cleaned before greasing. c) Do not lubricate with too high pressure: MAXIMUM PERMISSIBLE GREASE PRESSURE 6 BAR. d) Pump the grease in the bearings until the old lubricant flows out of seals or relief valves. NOTE: DO NOT LUBRICATE THE BOLTS OR NUTS WITH LUBRICANTS CONTAINING MoS2. e) Spacer side containing the splined shaft must be completely filled with grease. Lubricate in the minimum length compensation position. Do not pump more grease than required in the drawing. After lubricating make the spline slide with opened plugs once or twice. 2.13 Bearings and length compensator have been prelubricated at our workshop and do not require lubrication before installation in case of short period of storage. See section "LUBRICATION" for types of tube and intervals of lubrication. 2.14 If the setting at work takes place three months later than the assembly, check the conditions of universal shafts and relubricate. The lubrication points of standard universal shafts are placed respectively: - in the centre of journal cross or on each bearing bottom, to lubricate the bearings - on the spacer and on the cover to lubricate the length compensator. - self-locking nuts (according to DIN 980 - 10 or 8). The bolts are to be tightened with a dynamometrical wrench or another similar device, in accordance to the torque table of page 30 or our drawings. The self-locking nuts lose their features and must be replaced, after a certain period of operations (about 5 screwings and unscrewings). Normally the bolts are inserted from the companion flange side, fitting the tightening nuts on the flanges of the universal shaft. In special cases it is also possible to insert the bolts from the joint side or to use stud bolts. MAINA recommend the following lubrication intervals: 4) LUBRICANTS 4.1 For normal applications MAINA recommend mainly lithium thickened greases. 4.2 For temperature ranges from +90 to -30°C, use grease with Penetration 1 or 2, according to DIN 51804. Please contact MAINA if the temperature is outside this range. 3) LUBRICATION 3.1 46 The performance and working life of universal shafts greatly depend on a lubrication programme. Do not let the spline slide before lubricating it. ORGANI DI TRASMISSIONE INSTALLATION, MAINTENANCE AND LUBRICATION 4.3 For very important heavy duties MAINA recommend the following specification of lubricant: Thickener lithium Worked penetration 315¸325 possible 265¸295 Dropping point 174¸193°C possible 165°C Thickener percentage 7% Mineral oil 75% Oil viscosity at 40°C 1000¸1500 cSt Oil viscosity at 100°C 60¸100 cSt Addition agents EP type 2% MoS2 mineral addendum 5¸10% Timken EP OK load 18 kg Corrosion negative 5) MAINTENANCE 5.1 To ensure a trouble-free life of the universal shafts, a maintenance schedule and a lubrication programme are essential. The following should be taken as a guide, the frequency of inspections depending on working conditions and type of equipment the universal shafts are installed on. 5.2 INITIAL INSPECTION 1st check after approx 1 week 2nd check after approx 2¸3 weeks 3rd 5.3 MAINA recommend the following greases for universal shaft size equal to or bigger than size 39 and for heavy duty conditions (rolling stand): CASTROL CASTROL MOLUB-ALLOY 870 WULKEN MOLUBROL W/PA10 OPTIMOL LONGTIME PD2 KLUBER KLUBERLUB BE41-1501 MOBIL MOBILUX EP111 SIGNAL MOLYVIS GLA SPECIAL 1) Bolts Tighten when necessary. 2) Wear Check the following: - radial clearance of bearings - end float of the journal cross - radial clearance of the slip stub shaft - torsional clearance of the slip stub shaft 3) Noise/Nibration Any unusual sound or excessive vibrations should be located and corrected immediately. 4) Temperature Make sure that bearings do not exceed the ambient temperature by more than 35¸40°C. 5) Position of the companion flanges Check that the supports have not yielded because of base settlements or deformations. 6) Lubrication Check that no grease dripping i s p r e s e n t , d u e t o centrifugation or other causes, i.e. wear or breakage of seals, wear or loss of grease nipples, plugs or relief valves. - contain oxidation inhibitors - be water-repellent - have a good thermal stability. 4.4 For high operation speed (>500 rpm), the addition agents must have a good resistance to centrifugation. 4.5 For moderate industrial services MAINA recommend the following greases: BP ENERGREASE LS2 ESSO BEACON EP2 SHELL ALVANIA EP2 MOBIL MOBILUX 2 TEXACO MULTIFAK EP2 REGULAR INSPECTION Every 1000¸2000 working hours or, at least, once a year for light applications and every six months for heavy duty applications. The periodical checks are to be carried out as follows: Greases must also: - be free of alkalis, acids, impurities check after approx 4¸6 weeks Synthetic greases may also be used. 4.6 The right type of grease to employ is shown in the drawing. For grease quantity see page 41.
