The following balancing standards must be observed:
?Subassemblies and coupling parts are designed with standard balancing quality.
?Fine balancing and microbalancing are available to order.
?Higher balancing qualities are provided on request, after technical clarification.
?Hub parts without finished bore are not balanced.
?FLUDEX couplings are subject to special balancing standards.
?ARPEX couplings in standard balancing quality are unbalanced. The balancing quality of standard balancing is nearly always adhered to by steel components which are machined all round and precisely guided adapters.
?The number of balancing levels (single- or two-level balancing) is specified by FLENDER.
?Unless otherwise requested, the unit is balanced in accordance with the half parallel key standard. Balancing in accordance with the full parallel key standard must be specified in the product code.
Shaft-hub connections
The bore and the shaft-hub connection of the coupling is determined by the design of the machine shaft. In the case of IEC standard motors the shaft diameters and parallel key connections are specified in accordance with DIN?EN?50347. For diesel motors the flywheel connections are frequently specified in accordance with SAE?J620d or DIN?6288. Besides the very widely used connection of shaft and hub with parallel keys to?DIN 6885 and cylindrically bored hubs, couplings with taper clamping bushes, clamping sets, shrink-fit connections and splines to DIN?5480 are common.
The form strength of the shaft/hub connection can only be demonstrated when shaft dimensions and details of the connection are available. The coupling torques specified in the tables of performance data of the coupling series do not apply to the shaft-hub connection unrestrictedly.
In the case of the shaft-hub connection with parallel key the coupling hub must be axially secured e.g. with a set screw or end plate. The parallel key must be secured against axial displacement in the machine shaft.
All FLENDER couplings with a finished bore and parallel keyway are designed with a set screw. The exceptions are some couplings of the FLUDEX series, in which end plates are used. During assembly taper clamping bushes are frictionally connected to the machine shaft.
Assembly
Assembly, start-up, maintenance and servicing of the coupling are described in the operating instructions.
Contact protection
Couplings are rotating components which can pose a risk to the environment. FLENDER in the operating instructions prescribes fitting couplings with a suitable contact guard, also called a coupling guard. The contact guard must provide a firm cover to protect against contact with the rotating coupling. The coupling must also be protected against blows from objects striking it. The coupling guard must enable the coupling to be adequately ventilated. The following guidelines give information on designing the contact guard: 2006/42/EC EC Machinery Directive; EN?13463-1 Section?13.3.2.1; EN?13463-1 Section?7.4; EN?13463-1 Section?8.1.
Maintenance
All-steel membrane couplings of the ARPEX series require no maintenance. If the operating and mounting conditions have been adhered to, only regular visual inspection is required.
Elastomer elements, elastomer seals and lubricants are subject to wear through ageing and loads. To avoid damage to the coupling or failure of the drive, the ZAPEX, N-EUPEX, N-EUPEX DS, RUPEX, BIPEX, ELPEX, ELPEX-S, ELPEX-B and FLUDEX series must be maintained in accordance with the operating instructions.?
On gear couplings the lubricant must be changed at regular intervals.
On flexible or highly flexible couplings the torsional backlash or the torsion angle must be checked at regular intervals under load. If a limit value is exceeded the elastomer element must be replaced. It is very important to maintain couplings which are operated in a potentially explosive environment, as couplings which are not maintained can become ignition sources.
Corrosion protection
Depending on the environmental conditions, suitable corrosion protection must be specified for the coupling. Unless otherwise specified in the order, steel and cast iron surfaces are shipped with a simple preservative.
Ambient conditions
Because of the environment the coupling has to meet a large number of additional requirements. Couplings must be as suitable for use in a potentially explosive environment as for use at a high or low ambient temperature. The environment may be defined as chemically aggressive or be subject to laboratory conditions or requirements of food manufacture.
ATEX and EC Machinery Directive
Wherever a potentially explosive environment cannot be ruled out the machinery used must meet special conditions in order to prevent the outbreak of fire as far as possible. Within the European Union, Directive 94/9/EC applies to these applications. This directive, also called ATEX 95, harmonizes the individual states' legal requirements for explosion prevention and clearly defines the procedure for checking and circulating machines and parts.?
Whether or not a machine is used in a potentially explosive environment, the manufacturer is required under EC Machinery Directive 98/37/EC to assess and as far as possible prevent hazards which may arise from his product.
The operator has an obligation to ascertain whether an environment is potentially explosive. Details of this are laid down in Directive 1999/92/EC, also known as ATEX?137.
The manufacturer is responsible for ensuring that the product is safe as defined in the EC Machinery Directive and conforms to Directive 94/9/EC, if the EX requirement is specified by the operator.
The drive train mostly comprises individual pieces of equipment which are put together to form a subassembly. If the individual pieces of equipment, such as the motor, coupling, gear unit or driven machine, conform to Directive 94/9/EC, the manufacturer of the overall unit can limit the risk assessment to the additional hazards which arise from the combination of different individual pieces of equipment. The hazards which can arise from the individual pieces of equipment are assessed by the relevant suppliers.
All FLENDER couplings conform to the requirements of the EC Machinery Directive 98/37/EC.
The coupling series suitable for use in potentially explosive environments are marked EX.
Coupling behavior during overload conditions
Behavior under overload where the torque is considerably above the limits of use of the coupling concerned is determined by the engineering design of the coupling series.
The ZAPEX, ARPEX, N-EUPEX, RUPEX and BIPEX coupling series can withstand overloads until the breakage of metal parts. These coupling series are designated as fail-safe. Coupling types which can withstand overload, i.e. fail-safe types, are used e.g. in crane systems.
The N-EUPEX DS, ELPEX-B, ELPEX-S and ELPEX coupling series throw overload. The elastomer element of these couplings is irreparably damaged without damage to metal parts when subjected to excessive overload. These coupling series are designated as non-fail-safe. The types that fail can be fitted with a fail-safe device. This component enables emergency operation, even after the rubber element of the coupling has been irreparably damaged.
The fluid couplings of the FLUDEX series withstand a load for a short time. Persistent overload causes the FLUDEX coupling to heat up beyond limits, causing the fuse to operate and so emptying the coupling and interrupting the torque transmission.
Torsional and bending vibrations
On drives which are prone to torsional and bending vibrations, calculations such as natural frequency calculations, torsional vibration simulations or bending vibration calculations are necessary.
The drive train may, depending on complexity, be regarded as a two-mass vibration-generating system or N-mass vibration-generating system. The vibration-generating masses are defined by the rotating bodies and the couplings by the coupling stiffnesses and shaft stiffnesses. The effect of torsional vibration excitations on the behavior of the system is calculated.
Torsional vibration excitations may occur during the starting of an asynchronous motor, during a motor short circuit or in diesel engine drives. Bending vibrations may be critical, if the coupling is insufficiently balanced and/or at an operating speed close to the critical speed.
The details needed for calculating torsional vibration
?Dynamic torsional stiffness
?Damping (specification of the damping coefficient ψ or Lehr's damping D?=?ψ/4π).
?Mass moment of inertia of the coupling halves are specified in the coupling catalog.
