Description

Изобретение относитс к машиностроению и может быть использовано в приводах канатных дорог, лифтов и других устройствах , осуществл ющих передачу крут щего момента с помощью гибкой т ги.The invention relates to mechanical engineering and can be used in drives of cableways, elevators and other devices that transmit torque using flexible traction.

Цель изобретени - повыщение долговечности щкива за счет устранени износа в соединении подвижный диск - ступица.The purpose of the invention is to increase the durability of the face by eliminating wear and tear in the joint between a movable disk and a hub.

На чертеже изображен канатоведущий шкив, общий вид, осевой разрез.The drawing shows a traction sheave, general view, axial section.

Шкив содержит ступицу 1, с которой св заны диски 2 и 3, имеющие обода 4, 5 с ребордами, образующими ручей под канат. Диск 2 жестко закреплен на ступице 1, а диск 3 установлен под углом к диску 2 и выполнен в виде упругой мембраны, жестко св занной с ободом 5 и со ступицей 1.The pulley comprises a hub 1, with which the disks 2 and 3 are connected, having rims 4, 5 with flanges forming a stream under the rope. The disk 2 is rigidly fixed to the hub 1, and the disk 3 is installed at an angle to the disk 2 and is made in the form of an elastic membrane rigidly connected to the rim 5 and to the hub 1.

На ступице 1 установлены также опорный диск 6, взаимодействующий с диском 3, и дистанционные кольца 7, фиксируемые вместе с дисками 3 и б на ступице 1 с помощью стакана 8 и болта 9.The hub 1 is also equipped with a supporting disk 6, which interacts with the disk 3, and distance rings 7, fixed together with the disks 3 and b on the hub 1 by means of a glass 8 and a bolt 9.

Канатоведущий шкив работает следую- образом.The traction sheave works as follows.

При вращении шкива с нагруженным канатом в местах набегани и сбегани каната ширина ручь , образуемого ободами 4 и 5 дисков 2 и 3, обеспечивает свободный вход в ручей и выход из него каната, зажиWhen the pulley rotates with the loaded rope in the places where the rope runs and runs down, the width of the stream formed by the rims 4 and 5 of the disks 2 and 3 ensures free entry and exit of the rope to the stream

маемого в ручье между ободами 4-и 5. При этом наклон обода 5 обеспечиваетс за счет деформации упругой мембраны диска 3. От чрезмерной деформации упругую мембрану предохран ет опорный диск 6. Посредством перестановки колец 7 осуществл ют изменение угла наклона обода 5 диска 3.The rim 5 is provided due to the deformation of the elastic membrane of the disk 3. The supporting disk 6 prevents the elastic membrane from over-deforming the elastic membrane. By reversing the rings 7, the angle of inclination of the rim 5 of the disk 3 is changed.

Claims

The invention relates to mechanical engineering and can be used in drives of cableways, elevators and other devices that transmit torque using flexible traction. The purpose of the invention is to increase the durability of the face by eliminating wear and tear in the joint between a movable disk and a hub. The drawing shows a traction sheave, general view, axial section. The pulley comprises a hub 1, with which the disks 2 and 3 are connected, having rims 4, 5 with flanges forming a stream under the rope. The disk 2 is rigidly fixed to the hub 1, and the disk 3 is installed at an angle to the disk 2 and is made in the form of an elastic membrane rigidly connected to the rim 5 and to the hub 1. On the hub 1 there are also installed a supporting disk 6 interacting with the disk 3, and spacer rings 7 fixed together with discs 3 and b on hub 1 with the help of cup 8 and bolt 9. The wheel drive pulley works in the following way. When the pulley rotates with the loaded rope in the places where the rope runs and runs down, the width of the stream formed by the rims 4 and 5 of disks 2 and 3 provides free entry into and out of the rope of the rope clamped in the stream between the rims 4 and 5. At the same time 5 is provided due to the deformation of the elastic membrane of the disk 3. The supporting disk 6 protects the elastic membrane from excessive deformation. By reversing the rings 7, the angle of inclination of the rim 5 of the disk 3 is changed. Invention formula. A traction drive pulley comprising a hub and two rims with rims having flanges forming a stream under the rope, the first of which is rigidly fixed on the hub and the second is mounted on the hub at an angle to the first one, characterized in that the second disk is made in the form of an elastic membrane rigidly connected to the rim and the hub, and the pulley is provided with a supporting disk mounted on the hub and interacting with the elastic membrane.

2. The pulley according to claim 1, characterized in that, in order to adjust the angle of inclination of the discs relative to each other, the pulley is equipped with a glass mounted on the hub with a bolt and a set of spacer rings securing the second and supporting discs as they axially move.
