Description

1 90647 sahkttinen nostolaite1 90647 electric hoist

Esilia oleva keksintd kohdistuu sShkOiseen nosto-laitteeseen, joka kasittaa kannatinrunkoon sijoitetun rum-« 5 mun, ja sahkOmoottorin, joka on asennettu kannatinrunkoon ja kytketty kytkimen vaiitykselia planeettapyttrSstttdn, jonka kotelo on sijoitettu kokonaan rummun sisåån. Laitet-ta voidaan kayttaa tavarankasittelykoneissa.The present invention relates to a mobile lifting device for a drum housed in a support frame, and to an electric motor mounted on a support frame and connected by a switch-like planetary gun, the housing of which is located completely inside the drum. The device can be used in goods handling machines.

Ennestaan tunnettu kaapelin rumpukayttdlaite kasit-10 taa koteion sisaan sijoitetun planeettapyOrastttn, joka on kytketty sahkOmoottoriin, joka on asetettu kannatinrunkoon asennetun rummun paatypinnan eteen, joka on kytketty pla-neettapydrastOiin sen viimeisen portaan kantaosan avulla. Kotelo on kiinnitetty rumpuun laipoilla (DE-patenttijul-15 kaisu 26 012 244).A previously known cable drum drive device comprises a planetary gear housed inside a housing and connected to an electric motor placed in front of the end face of a drum mounted on a support frame, which is connected to the planetary gear by means of a base of its last stage. The housing is fastened to the drum by flanges (DE patent publication 15 012 244).

Taman tunnetun kayttdlaitteen haittapuolina ovat sen suhteellisen pieni luotettavuus, mika johtuu jaykasta kytkennasta planeettapyOrastdn vaiilia, ja rummun ylimi-toituksen tarpeesta, jonka maaraa sahkOmoottorista tule-20 van vaantttmomentin vaiitysarvo planeettapyOrastOn ensim-maiseen portaaseen.Disadvantages of this known drive device are its relatively low reliability due to the rigid coupling of the planetary valves, and the need for overdrive of the drum, which is determined by the silence value of the torque coming from the electric motor to the first stage of the planetary motor.

Esilia olevan keksinnttn yleisena tavoitteena on siten aikaansaada sahkttinen nostolaite, jonka rumpukayt-tttlaite on luotettavampi ja jonka rakenne on sellainen, 25 etta metallin ominaiskulutus on pienempi.It is therefore a general object of the present invention to provide an electric hoisting device which is a more reliable drum drive device and which has a structure such that the specific consumption of metal is lower.

Tama tavoite saavutetaan sahkttiselia nostolaitteel-la, jolle keksinndn mukaan on tunnusomaista, etta kotelo on rummun kanssa kinemaattisessa kytkennassa hammaslevyn ja rumpuun kiinteasti kytketyn hammaskehan vaiitykselia, 30 ja kannatinrunko on liitetty kytkinakselin vaiitykselia ' planeettapydJrastdSdn.This object is achieved by an electric lifting device, which according to the invention is characterized in that the housing is in kinematic engagement with the drum by means of a toothed plate and a toothed ring fixedly connected to the drum, and a support body is connected to the coupling shaft.

Esilia olevan keksinndn mukaisen sahkOisen nosto- laitteen etuina ovat sen lisaantynyt luotettavuus, mika johtuu lahtOakselin ja kannatinrungon vaiisesta voiman- 35 siirtoakselin avulla aikaansaadusta elastisesta kytken- 2 90647 nasta, ja rummun pienentyneesta kokonaiskoosta, mika joh-tuu sahkOmoottorin akselin ja planeettapyOrastOn ensim-maisen portaan vaiisesta kinemaattisesta kytkennasta.The advantages of the electric hoisting device according to the present invention are its increased reliability due to the silent coupling provided by the output shaft and the support frame by means of a resilient transmission shaft, and the reduced overall drum size of the drum. silent kinematic coupling.

Esilia olevan keksinnOn paremmaksi ymmartamiseksi 5 viitataan mukana seuraavaan piirustukseen, jossa esite-taan keksinnOn mukaisen sdhkOisen nostolaitteen osittainen poikkileikkauskuva.For a better understanding of the present invention, reference is made to the accompanying drawing, which shows a partial cross-sectional view of a sdhkO hoist according to the invention.

SahkOinen nostolaite kasittaa koteion 2 sisaan si-joitetun planeettapyOrastOn 1, joka on kytketty kytkimen 3 10 avulla sahkOmoottoriin 4, joka asetettu kannatinrunkoon 6 sijoitetun rummun 5 paatypinnan eteen. Tama kannatinrunko 6 on kytketty planeettapyOrastOOn 1 viimeisen planeetta-portaan 8 kantaosan 7 avulla. Kotelo 2 on kytketty rumpuun 5 hammaslevyn 9 ja hammaskehan 10 avulla. Kantaosa 7 on 15 kytketty lahtOakselin 11, voimansiirtoakselin 12 ja ura-liitosten 13 ja 14 avulla kannatinrunkoon 6. Hammaskeha 10 on kiinnitetty kiinteasti rumpuun 5, joka on sijoitettu laakerien 15 avulla kannatinrunkoon 6.The electric hoist handles a planetary gear 1 located inside the housing 2, which is connected by means of a switch 3 10 to an electric motor 4 placed in front of the end surface of the drum 5 placed in the support frame 6. This support frame 6 is connected to the last planetary stage 8 of the planetary structure 1 by means of a base part 7. The housing 2 is connected to the drum 5 by means of a toothed plate 9 and a toothed ring 10. The base part 7 is connected to the support body 6 by means of a camshaft 11, a transmission shaft 12 and groove connections 13 and 14. The toothed ring 10 is fixedly attached to a drum 5 which is placed by means of bearings 15 in the support body 6.

Esilia olevan keksinnOn mukainen sahkOinen nosto-20 laite toimii seuraavasti:The electric hoist-20 device according to the present invention operates as follows:

SahkOmoottorin 4 vaantOmomentti vOlitetaan kytki-men 3 ja planeettapyOrastOn 1 portaiden avulla koteloon 2 ja sielta hammaslevyn 9 kautta hammaskehaile 10. Koska kantaosa 7 on kytketty uraliitosten 13 ja 14 seka voiman-25 siirtoakselin 12 avulla kannatinrunkoon 6, vastaanottaa rumpu 5 tasaisen pyOrimisliikkeen.The pitch torque of the electric motor 4 is transmitted by means of the steps of the switch 3 and the planetary gear 1 to the housing 2 and from there through the toothed plate 9 to the gear frame 10. Since the base part 7 is connected to the support frame 6 by the groove connections 13 and 14
