Description

Изобретение относитс к подъемно- тран:спортному машиностроению, а именно к механизмам передвижени кранов.FIELD OF THE INVENTION The invention relates to lifting and transport machinery, in particular, to crane movement mechanisms.

Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.

/Механизм передвижени крана содержит с к;1ждой его боковой стороны балансир- ные тележки, ходовые колеса 1 и 2, одной из :оторых св заны с приводом их врааце- ни Ходовые колеса 3 и 4 другой тележки вл;1ютс холостыми. Колеса 1 к 2 через муфты 5 св заны с редуктором 6, соединенным через муфту 7 с электродвигателегп 8. Р едуктор б включает в себ последова- тел1но сопр женные зубчатые колеса 9-Г2, последнее из которых жестко соединено со своим валом 13. Колесо 9 свободно установлено на валу 14, а колеса 0 к 11 - на ос х 15 и 16. Валы 13 и 14 св заны с ходовыми колесами 2 и 1. Вал 17 св зан с электродвигателем 8 и несет центральную шесTepi/ The crane movement mechanism contains with k; 1 each side of it, the balance trolleys, travel wheels 1 and 2, one of which: they are connected with the drive of their rifle The travel wheels 3 and 4 of the other vehicle; Wheels 1 to 2 through couplings 5 are connected to gearbox 6, connected via coupling 7 to electric motor 8. Gear box b includes sequentially mated gears 9-G2, the last of which is rigidly connected to its shaft 13. Wheel 9 Freely mounted on the shaft 14, and the wheels 0 to 11 - on the axles 15 and 16. The shafts 13 and 14 are connected with the driving wheels 2 and 1. The shaft 17 is connected to the electric motor 8 and carries the central gear

При разных диаметрах ходовых колес 1 и 2 происходит перераспределение угловых скоростей валов 13 и 14. Механизм имеет относительно большие передаточные отношени , что позвол ет при большой грузоподъемности крана сн ть ограничение на чис- 10 ло полюсов электродвигател 8.shaft 14, and on the other via epicycle 21, disk 22, wheels 9-12 - shaft 13. Gear ratios from shaft 17 to shafts 13 and 14 are the same Shafts 14 and 13 vras, running wheels 1 and 2. For different diameters of the driving wheels 1 and 2, the angular velocities of the shafts 13 and 14 are redistributed. The mechanism has relatively large gear ratios, which makes it possible to remove the limitation on the number of poles of the electric motor 8 when the crane has a large lifting capacity.

Claims

Invention Formula

drove 20, made in one with the shaft 14. | Satellites 19 are coupled with an epicyclic 21, I with which the disk with 22 is rigidly and coaxially connected, made with teeth 23 on its inner surface, mated to the knees 9. Wheels 9 -11, satellites 19 and shafts 13 til 14 are mounted in self-aligning - spherical bearings 24. Shaft 17 can be mounted in non self-aligning bearings 25. Shaft 17 is installed, flax on one side in gearbox housing 6, and shaft end 17 freely located in the nest 26 of the shaft 14 from the side of the carrier 20.

MexaHH3iM works in the following way.

The power of the electric motor 8 is transmitted through the sixteen to the satellites 19, which on one side drove the turn of the 20 vras, ay

The mechanism for moving the crane contains, on each side of it, the balance trolleys, the running wheels of one of which are connected to the drives of their rotation, including an electric motor connected to the shaft carrying

20 central gear connected to the satellites mounted on the carrier and associated with the epicycle, and at least four gear wheels connected in series with each other, and shafts for coupling to the driving wheels arranged parallel to each other and bearing respectively

the first and fourth gears, the last of which is rigidly connected to its shaft, characterized in that, in order to increase reliability, it is provided with a disk,

with teeth on its inner surface fixed on the epicyclic coaxially with the last one and mated with the first gear wheel, freely mounted on its shaft, made in one with the said carrier and having on its side

:, with a socket, 3 of which is freely mounted the end of the shaft of the central gear, and the axes arranged parallel to the shafts and carrying the second and third gears, respectively.
