Известна лебедка, содержащая редуктор и барабан, установленный на валу, связанном посредством зубчатой муфты с валом редуктора, причем в торце вала редуктора выполнена кольцевая проточка, в которой установлен сферический подшипник, охватывающий вал барабана и закрепленный на нем посредством торцевой шайбы [1].A known winch containing a gearbox and a drum mounted on a shaft connected by means of a gear coupling with the gearbox shaft, wherein an annular groove is made in the end of the gearbox shaft, in which a spherical bearing is installed, covering the drum shaft and fixed to it by the end plate [1].

Известная конструкция лебедки имеет тот недостаток, что наружная обойма зубчатой муфты закрывает доступ к подшипнику в период сборки, и, вследствие неизбежных перекосов наружного кольца подшипника, процесс сборки затруднен.The known design of the winch has the disadvantage that the outer race of the gear clutch blocks access to the bearing during assembly, and, due to the inevitable distortions of the outer race of the bearing, the assembly process is difficult.

Цель изобретения .— облегчение сборки лебедки.The purpose of the invention is to facilitate the assembly of the winch.

Цель достигается тем, что сферический подшипник снабжен кольцом, взаимодействующим с его наружной обоймой и закрепленным в барабане внутри зубчатой муфты соосно подшипнику с возможностью осевого перемещения.The goal is achieved in that the spherical bearing is provided with a ring interacting with its outer cage and fixed in the drum inside the gear coupling coaxially to the bearing with the possibility of axial movement.

На фиг. 1 показана лебедка, общий вид; на фиг. 2 — разрез А—А на фиг. 1 (по сое2 динению барабана с редуктором в период сборки; на фиг. 3 — то же (после сборки).In FIG. 1 shows a winch, a general view; in FIG. 2 — section A — A in FIG. 1 (by connecting the drum with the gear during assembly; in Fig. 3 - the same (after assembly).

Лебедка включает барабан 1 с валом 2, опирающимся на подшипники 3 и 4. Под5 шипник 4 установлен в кольцевой проточке, выполненной в торце вала 5 редуктора 6. Валы барабана и редуктора связаны между собой зубчатой муфтой 7. Подшипник 4 сферический, что позволяет компенсировать перекосы вала барабана. Внутри зубчатой муфты 7 установлено кольцо 8 с возможностью осевого перемещения посредством винтов 9.The winch includes a drum 1 with a shaft 2, supported by bearings 3 and 4. Pod5 bearing 4 is installed in an annular groove made in the end of the shaft 5 of the gearbox 6. The shafts of the drum and gearbox are connected by a gear coupling 7. The bearing 4 is spherical, which allows you to compensate for distortions drum shaft. Inside the gear clutch 7, a ring 8 is mounted with the possibility of axial movement by means of screws 9.

Лебедка работает следующим образом.The winch operates as follows.

При включении электродвигателя 10 кру15 тящий момент на барабан 1 передается через редуктор 6, вал 5, зубчатую муфту.7. При вращении барабана I происходит навивка каната.When the motor 10 is turned on, the torque to the drum 1 is transmitted through a gearbox 6, a shaft 5, a gear clutch. 7. When the drum I rotates, the rope coils.

Соединение барабана 1 с редуктором 6 ²⁰ при монтаже лебедки производят в следующей последовательности.The connection of the drum 1 with the gearbox 6 ²⁰ during the installation of the winch is carried out in the following sequence.

Сначала к торцу вала 2 крепят винтами базовую шайбу 11, которая служит опорой наружной обойме подшипника 4.First, the base washer 11 is fixed to the end of the shaft 2 with screws, which serves as a support for the outer race of the bearing 4.

Винтами 9 перемещают кольцо 8 в направлении подшипника 4. После соприкосновении кольца 8 с наружной обоймой подшипника 4 при дальнейшем его перемещении, оно переместит наружную обойму до е.е упора в шайбу 11. Поскольку шайба 11 ⁵ перпендикулярна валу 2, наружная обойма подшипника окажется правильно сориентированной относительно вала 2. Перед сборкой шайба 11 снимается и заменяется торцевой шайбой 12. ₁₀ Screws 9 move the ring 8 in the direction of the bearing 4. After the ring 8 is in contact with the outer race of the bearing 4, when it is moved further, it will move the outer race to the washer 11. Since the washer 11 ^{5 is} perpendicular to the shaft 2, the outer race of the bearing will be correct oriented relative to the shaft 2. Before assembly, the washer 11 is removed and replaced by an end washer 12. ₁₀

При этом все операции выполняются на барабане 1, когда он еще находится в стороне от редуктора 6.In this case, all operations are performed on the drum 1, while it is still away from the gear 6.

На фиг. 2 редуктор и барабан показаны в том положении, когда подшипник 4 находится у входа в кольцевую проточку, но is это чисто условно.In FIG. 2 the gearbox and drum are shown in the position when the bearing 4 is at the entrance to the annular groove, but is this is purely arbitrary.

Перемещая барабан 1 в направлении к редуктору 6, вводят подшипник 4 в кольцевую проточку вала 5 редуктора 6.Moving the drum 1 in the direction of the gear 6, enter the bearing 4 into the annular groove of the shaft 5 of the gear 6.

С помощью винтом 9 отводят кольцо 8 в правое крайнее положение и стопорят гайками 13.With the help of a screw 9, the ring 8 is taken to the right extreme position and locked with the nuts 13.

Дальнейшая сборка не вызывает трудностей и не требует специальной оснастки.Further assembly does not cause difficulties and does not require special equipment.
