Introduction

Advantages arising from use of Henfluid hydrodynamic couplings

Functioning

Henfluid hydrodynamic couplings havebeen developed and designed by em-

ploying the most up-to-date engineering

concepts resulting in a product of thehighest technical standard and excellent

operating performance. Carefully dimen-

sioned models were elaborated for proj-ects with power requirements from 02 to

2500 HP.

Start-up of electric motor under no-

load conditions, even when the machine

r ven s oa e or oc e ;

Immediate drop of motor start-up cur-rent;

Smooth acceleration of heavy loads

without use of overdimensioned motors.

The maximum motor torque is normallyrequ re a s ar -up, u an s o e

use of Henfluid hydrodynamic couplingsthe motor can be dimensioned based on

the power actually required by the ma-

chine driven;

Coupling reduces maximum torque

providing efficient protection of the motoras well as of the machine driven and the

product being manufactured, irrespec-

tively of the load to which the secondary

rotor (exit shaft) is subjected. While the

secon ary ro or may as muc as s a

(100% slippage) on account of the over-load, the primary rotor (entry shaft) will

go on urnng.

Adjustments of the maximum torque

transmitted are achieved by simply ad-us ng e vo ume o e o c arge;

Even load distribution among all themotors in case of multiple drive. Start-

up can be made to occur in sequence

thereby avoiding high peaks of power

consump on;

Complete protection against overheat-ing. In case of prolonged blocking of the

secondary rotor (stall), a fuse plug is trig-

gered emptying the coupling and thus

interrupting transmission;

Power transmission free from wear,

seeing that there is no mechanical con-tact between the driven and the driving

par s;

Great economy through protection of

all the electrical and mechanical drivee emen s, even w en ro a on commu a-

tion / reversal occurs at high frequency; In consequence of the above advantag-

es, Henfluid hydrodynamic couplings of-

fer a vast range of industrial applications,

suc as: conveyors, m nera ex rac on,

mineral processing, chemical and foodindustries, machines with great start-up

ner a, e c.

pump ro or an e o er one e ur nerotor, in addition to a plain carcass which

ou es as an o reservo r con a n ng einternal rotor.

Functioning

Idle position

The driving machine provides the energy to ac-celerate the working fluid so as to generate aound-about current. Due to the transmission ofhe kinetic energy by the fluid, the internal rotors put in motion.

The working fluid remains static inside the cou-ling.

uring normal operation only the torque requiredby the machine driven is transmitted by the cou-pling which is designed to absorb possible over-loads without passing these on to the drivingmachine.

Start-up Normal operation

The rotors are fitted one facing the otherwith a pre-determined clearance, without

any mechanical contact between them.

The Henfluid hydrodynamic couplingworks like a centrifugal pump and a

hydraulic turbine. By means of an en-try force (conventional electric motor or

electric ring motor), the kinetic energy is

transmitted by the oilfill inside the cou-pling. The oil is accelerated by the pump

rotor and through centrifugal force the

movemen s ransm e o e ur nerotor; the torque thus generated is trans-

mitted to the secondary hub and, conse-quen y, o e mac ne r ven.

Any one of the rotors can assume the

task of pump or turbine, depending onthe direction of assembly. Wear is practi-

cally inexistent as there is no mechanical

contact, and the efficiency of the systemis only dependent on the difference be-

tween the entry and exit rotation of thecoupling (slippage).

pensive electric induction motor Henfluid

hydrodynamic couplings offer a vast field

of applications, permitting start-ups with-

out acceleration resistance and reaching

operating rotation quickly and at a lowpower consump on, as oppose o sys-

tems without start-up protection.

At conclusion of the acceleration pro-

cess and keeping in mind the couplings

low slippage factor, only the torque effec-

tively necessary for the functioning of themachine driven will have been required

from the electric motor.

maximum start-up torque of up to 160%

of nominal torque. Configuration H-RR

is with elongated retarding chamber usedfor large inertia systems which require

limitation of maximum start-up torque by

up to 140% of nominal torque.

As shown in the graph, the resulting

positive acceleration torque is sufficient

or e e ec r c mo or o qu c y reac sasynchronous rotation and thus present

ideal conditions to help accelerating the

machine driven, job which is now taken

over by the coupling. Henfluid hydro-dynamic couplings also provide oil flow

simple or elongated and the operatingchamber by means of calibrated oil flow

mechanisms, permitting various combi-

nations of oil outflow x acceleration time

x torque limitation, optimizing the start-up conditions for all drive types.

They are used for belt conveyors, chain

conveyors, centrifuges, mills, machines

with great inertia, etc.

Power transmission is the result of the oilcircuit type and the volume of the opera-

ting chamber of HENFLUID hydrodyna-

mic couplings; these features determineconsumption of electricity during start-

up, minimum starting torque, torque evo-

lution during acceleration of the machinedriven and torque transmitted under nor-

mal operating conditions.

Features

This type features an elongated retarding

chamber and auxiliary start-up chamber.

When using type A auxiliary start-up

chambers, it is possible to remove at the

moment of start-up a significant quantity

of oil initially contained in the operating

chamber (rotors) of the hydrodynamic

coupling, facilitating acceleration of the

motor and providing for the system driv-

en a start-up torque limitation of between

95% and 120% of the electric motors

nominal torque.

pon conc uson o acce era on o e

electric motor, the RR elongated re-

tarding chamber restores to the workingchamber the oil volume previously re-

moved on start-up by the auxiliary cham-

ber A, re-establishing operating condi-

tions of the hydrodynamic coupling.

The oil outflow rate from the rotors to the

aux ary s ar -up c am er a e eg n-

ning of acceleration of the electric mo-

tor is many times higher than the outflow

provided by the passage valves; these

can be regulated through the combina-

tion of graduated apertures, in accor-

dance with the start-up conditions of ev-

ery equ pmen n par cuar.The principal function of the auxiliary

start-up chamber A is to provide maxi-

mum start-up torque relief for the drive

systems that use medium and high ten-

sion short circuit motors and cage rotors,

permitting that these motors accelerate

without load. Special attention should be

g ven o e ca egory s mp e cage ro or

electric motors which show high perfor-

mance in asynchronous rotation with low

initial start-up torque.

Type HLE-RRA Henfluid hydrodynamic

couplings are recommended for large in-

ertia drive systems, especially inclined or

no nc ne ong s ance e conveyors,

w s mp e or mu p e r ve, w ere e

effects of transient tensions of the beltsare to be eliminated; these tensions oc-

cur during the so-called transition period,

i.e. from the belts stationary position at

start-up to the complete acceleration of

the system. It is observed in practice that

a conveyor e s no a r g sys em or a

constant torque machine, in view of the

known profiles of speed variation during

its acceleration.

These variations are originated by the

generation of shock waves stemming

from the natural speed difference be-

ween e op an o om en o econveyor which work at deferred operat-

ing speeds due to the belt flexibility. The

frequency and magnitude of the shock

waves depends on the a/tu ratio, where

a s e orque vara on rans erre y

the drive during the acceleration period,

and u is the oscillation time of low belt

speeds (see figure below). Consider-

ing that u cannot be changed because

epen s on e e ype an eng ,

the frequency and intensity of the shock

waves is directly related to a, i.e. evo-

lution time of acceleration torque of the

system. Therefore, the longer the time of

start-up torque increase, the lower the ef-

fect of the shock waves on the system.

The Hydrodynamic Couplings Henfluid were projected and designed within the newest

concepts of engineering, which propitiated the conceiving of a high technical standardand excellent work performance. Dimensioned after meticulous researches,

many models were designed to attend projects with all ranges of need, from

p o p.

Combined with an induction electric motor, Henfluid offers a huge field of utili-

zation. Allowing starts with no resistance to its acceleration, rapidly achievingthe desired work rotation, with little power consumption if compared to sys-

tems with no protected starts.

The Henfel Roller Bearing Units were designed considering the most

critical mechanical and environmental factors of solicitation, resulting ina durable product which lasts for a long time.

Developed in many series, the roller bearing units are perfectly inter-

changeable with all units found in the market today, whether they are

manufactured in Brazil or other countries. Besides, it can also be used

in specific projects, considering the situations and the load that the

The Henfel Flexible Coupling HXP is a coupling equipped with flexible

elements which become twisting elastic. Due to this, it has a wide fieldo app ca ons an can e use n s ua ons a eman a re a etorque transmission.

The elastic elements are assembled axially, and this allows the cou-

pling to work with radial, axial and angular disarrangements. They also

allow the absorption of vibrations and shocks coming from the machine

wor ng.

With the philosophy of offering the best to our clients, Henfel has invested

constantly in its Tooling Department. These investments contemplate themodernization of the machinery as well as the training and capacitating of

e personne nvo ve n p ann ng, qua y c ec an opera ons.

Capable of producing 150 tons a month, the Henfel Foundry Department relies on a highly qualified

crew, who uses up to date production processes and has been able to achieve excellent results in

the manufacturing and developing of parts, which meet with the most demanding and controlled

specifications.

Aiming to supply the machinery and equipments sector with high quality parts, the foundry depart-ment is ready to serve a wide range of needs and specifications concerning the alloys used, enabling
