Abstract

Tema ovog rada je konstrukcijska razrada kompaktnog mehanizma za dizanje, uz poseban zahtjev da se planetarni reduktor smjesti unutar volumena bubnja. Mehanizmi za dizanje sastoje se od motora, reduktora, kočnica, bubnja, faktorskog koloturnika te nosive konstrukcije. Vrsta reduktora je već definirana, pogon se standardno koristi elektromotorni, a bubanj jednoužetni s običnim faktorskim koloturnikom najvećeg prijenosnog omjera kako bi prijenosni omjer reduktora bio manji. Nadalje, potrebno je osmisliti kako će se planetarni reduktor učvrstiti na nosivu konstrukciju. Pritom je potrebno paziti da se osigura koncentričnost vratila i ležajeva na kojima će se bubanj uležištiti te mogućnost montaže. Planetarni reduktor se proračunava na temelju kinematske analize te se odabrani strojni dijelovi: zupčanici, vratila, ležajevi i spojke proračunavaju u skladu sa zadanim radnim karakteristikama koje mehanizam mora ispuniti.

Abstract (english)

The subject of this paper is to design compact lifting mechanism, with a special request
to place the planetary gear reducer within the drum volume. The lifting mechanism consists of
a drive unit, planetary gear reducer, brakes, drum, tackleblock and a support frame. Gear
reducer type is already assigned, the drive is electrial by deafult, single rope drum and
tackleblock is chosen with highest velocity ratio so that planetary gear reducer ratio is lower.
Furthermore, it is necessary to find a solution on how to fix a gear reducer on a support frame.
Also, it is necessary to ensure concentricity of the shaft and bearings on wich the drum will be
placed, as well as the possibility of mounting. Kinematic analysis of planetary gearbox is
performed to obtain expressions crucial for planetary gearbox calculations by means of which
other parts are selected and calculated
