Abstract. Starting of an electric motor drive with hydrodynamic
coupling is a transient operation regime beginning with the start of a
driving electric motor and lasting to its steady-state operation. It is
important to explore this process as it can be used as the basis for evaluation
of relevant parameters used for the choice of the motor and power transmission
elements. This includes the calculation of starting intervals of a driving
motor (it has to be short enough) and an output operating device (it has
to be long enough), determination of the thermal and mechanical loading
of driving mechanism elements, etc. The paper contains, as an example,
a proposition for a short and sufficiently exact calculation procedure
of a hydrodynamic coupling starting regime.
Key words: power transmissions, hydrodynamic couplings, transient
operation regime
ZALET ELEKTROMOTORNOG POGONA PREKO HIDRODINAMIČKE
SPOJNICE
Zalet elektromotornog pogona preko hidrodinamičke spojnice je prelazni
režim rada od uključivanja pogonskog elektromotora da postizanja stacionamog
stanja. Zalet je važno proučiti, jer se iz njega mogu odrediti veličine
bitne za izbor elemenata izvora i prenosa snage. Analizom zaleta moguće
je odrediti vreme zaleta pogonskcg motora, tj. proveriti da li je one dovoljno
kratkc. Moguće je odrediti i vreme zaleta radnog uređaja, tj. da li je
one dovoljno dugo. Takođe je moguće odrediti toplotno opterećenje elemenata
pogona i njihovo mehaničko opterećenje. Primer jednostavnog i dovoljno
tačnog proračuna kojim se određuju režimi zaleta hidrodinamičke spojnice
dat je u ovom radu.
