Description

The compact design, especially when it comes to electric winch, is achieved so that the bottom drum serves only as a room for the electric motor, the rotary inductor of the latter, so that a motor is obtained in which both parts rotate, and the relative speed is necessary due to an inductor and a gear created by the gear mechanism installed on the non-bottom part. Existing designs of such a pneut have the disadvantage that the installation and removal of individual parts of the winch is inconvenient.

The present invention, concerning the construction of the electric winch of the above structure, is intended to enable free access, as well as convenient installation and removal of individual parts. According to the invention, this is achieved by a device mounted on a case of a ball or roller bearing of such diameter that an electric motor integral with the drum can be BIJHJT pz of the winch casing while pulling it out of this casing. In the same way, the measles and the transmission mechanism for the brake can be installed and removed.

In FIG. 1 shows a longitudinal section of the proposed electric winch; FIG. 2 is a cross-section of it.

FIG. 3 is a top view of it with the trigger removed, FIG. 4-9 details.

A drum 11 is also installed in the housing 20, which also serves as an electric motor inductor, and the bark 13 rotates inside this drum, to which current is supplied through wires 29, slip rings 28, brushes 26 and collector 25. Mounted on the core axis Gear 15 interlocks with a gear wheel 16 , connected in turn, by means of the Zubchatka 17, with the toothed rim 18, mounted on the casing of the drum P. At the free end of the drum is placed the brake 30, which is activated by the brake magvptom 32 using the levers 31. The ball cage The ball bearing or roller bearing 12 is sized such that the toothed rim 18 freely passes through the bore for this bearing, while the bearing 12 located on the other hand is sized so that the gear 15 can pass through it. Since the toothed the rim 18 is mounted on the casing of the drum 11, then, Boc.ie beats the cover 43 of the winch casing and releasing the bracket 58 retaining the bearing 12, the drum can be pulled out of the casing 20 without having to remove the winch from the pestle, and the toothed rim is simultaneously disengaged 18c for 17 and gear 15

with a wheel 16. To remove the core 13 from the drum P, the bearing 14 by the wheel 13 and the gear 15 has such a diameter that the gear 15 can freely pass through the hole for this bearing, and if the additional part of the drum 11 is separated, which contains contact rings 28 brushes 26, with a lifting part of the drum 11, it is possible to remove the measles 13, while the lifting drum 11 can be left inside the case 20, which in this case is not removed from the place of its installation. In accordance with this, gear 16, 17 is arranged. After removing the cover 43 located on this side of the casing 20, and releasing the flanges 54 by unscrewing the screws 55 through the holes 56 in the wheel 16, you can remove all the gear 16, 17 through the hole for the shoulder 21 and again, in the same way, put it in place, since the underside of 21 is of such a diameter that the gear 17 passes freely through the opening for it. The implementation of sub-bearings 21 in the form of plain bearings with sliding friction is not necessary; can be used, as in this place, and in all others, ball or roller bearings. The brake 30 is made in the form of an internal brake; the brake is installed in an additional part of the drum; a chuck that, but removing the retaining ring 58, can be removed from the drum, with fixed points of rotation 57 for the brake levers located on the safety ring 58, while the brake levers 31 with the brake magnate 32 are uncoupled by removal from the corresponding axle. Thus, separate removal of the brake becomes apparent when the drum is removed. The brake magnet is designed in such a way that its measles 33 is held in one final end and the springs 75, which creates independence from the effect of weight. This allows you to arbitrarily install the brake magnet in the casing of the chain hoist, i.e. for example, with a horizontal axis, and makes also indifferent, in which it is in each case to install the winch. Starting device 70 is hinged; frontal plate 71 of the casing, so that it can be folded down, similar to the cover ,, and at the same time opens access to the inside of the casing (Fig. 3). In this connection, the wires 72 are connected in such a way that they do not have to be separated when it is necessary to create access to the inside of the casing. To attach the winch when installing, the cover is provided with edges 60, and for hanging,. in the case of the winch being used as a nolvpasta, making a cutout 62 in the connecting rib 61, forming an eyelet.

The subject of the patent.

An electric winch, which is characterized by the combined use of: a) a drum 11, which serves as an inductor and forms together with a motor 13 inside it, a motor, which is a drum bearing 12 at one end of such dimensions that the drum and the toothed rim 18 can be freely removed through the hole for the specified bearing, and from the other end is supplied with a hollow pin, held by the bearing 12 and forming the underside 14 for the core bore 13, which in its dimensions allows passage, the gear 15 on the specified core axis, Secondly, due to this, the bottom of the drum can be freely removed, whereby the gear 15 engages by means of the gear wheel 16 and the gear 17 with the aforementioned gear rim 18; b) an internal brake 30 installed in the additional part of the drum 11 and the interlocking ring 58, which can be freely removed after the tire,. while simultaneously disconnecting the brake levers 31 secured in it with the electromagnet 32, the measles 33 of which are held in one final position by the springs 75 and c) in the trigger 70 ,. hinged on the frontal plank 71 of the casing 20, provided with edges 60- for fastening it, and a notch 62 in the connecting rib 61-for suspending the casing. in the case of using the winch as an electrical unit, 1 is disassembled.
