(54) РОЛИК РОЛЬГАНГА(54) ROLLER ROLLER

1one

Изобретение относитс к промышленному транспорту, а именно - к приводным роликам .This invention relates to industrial vehicles, namely drive pulleys.

Известен ролик рольганга дл перемещени грузов с переменной скоростью, достигаемой путем измерени диаметра ролика {.A roller conveyor roller is known for moving loads with a variable speed achieved by measuring the roller diameter {.

Недостатком ролика вл етс необходимость применени специального приспособлени дл измерени его диаметра.The disadvantage of the roller is the need to use a special tool to measure its diameter.

Известен также ролик рольганга, содержащий приводной вал сц смонтированным на: нем корпусом, выполненным в виде сис«емы шарнирных т г, две из них присоединены к втулкам, одна из которых установлена на приводном валу на самотормоз щей резьбе, а втора - свободно 2J.Also known is a roller of the roller table, containing a drive shaft SC mounted on: a housing made in the form of a system of articulated joints, two of which are attached to bushings, one of which is mounted on the drive shaft on a self-braking thread, and the second is free 2J.

Этот ролик вл етс наиболее близким к изобретению по технической сущности н достигаемому результату.This video is the closest to the invention of the technical essence and the achieved result.

Недостатком такого ролика вл етс то, что дл его переналадки (увеличени и уменьшени диаметра) необходимо реверсировать- вращение ролика, что приводит . к снижению производительности из-за простоев ролика во врем его переналадки.The disadvantage of such a roller is that in order to change it (increase and decrease the diameter) it is necessary to reverse the rotation of the roller, which results. to decrease in productivity due to downtime of the roller during its changeover.

Целью изобретени вл етс повышение произБОдительностн рольганга.The aim of the invention is to improve the performance of the roller table.

Дл этого ролик снабжен дополнительным цепным приводом, звездочка которого жестко св зана с свободно установленной на валу втулкой.For this, the roller is provided with an additional chain drive, the sprocket of which is rigidly connected with a sleeve freely mounted on the shaft.

На чертеже схематически представлен ролик рольганга.The drawing schematically shows a roller conveyor.

Ролик содержит приводной вал 1, на котором установлены две втулки 2 и 3. Втулка 2 установлена на самотормоз щейс резьбе , а втулка 3 - свободно. Втулки 2 и 3 соединены между собой системой шарнирных т г 4, 5 и ,6. Т гн 4 и б имеют равную длину, а места их креплени к втулкам 2 и 3 отсто т от оси ролика на одинаковую величину. Поэтому т ги 5 оказыраютс параллельными оси ролика и всегда расположены в одной цилиндрической поверхности , образующей корпус ролика.The roller contains a drive shaft 1, on which two bushings 2 and 3 are mounted. Sleeve 2 is mounted on a self-braking cable, and sleeve 3 is free. Sleeves 2 and 3 are interconnected by a hinge system of r 4, 5 and 6. T n 4 and b are of equal length, and their attachment to the sleeves 2 and 3 are the same size from the roller axis. Therefore, the rods 5 are parallel to the axis of the roller and are always located in the same cylindrical surface forming the roller body.

Втулка 3 снабжена звездочкой 7 дополнительного привода. Втулка 3 зафиксирована от осевого перемещени вдоль вала 1 и может только вращатьс относительно него.The sleeve 3 is equipped with an asterisk 7 additional drive. The sleeve 3 is fixed against axial movement along the shaft 1 and can only rotate relative to it.

Ролик работает следующим образом.The video works as follows.

Claims

Shaft 1 and sleeve 3 rotates from their drives at the same angular velocity. (synchronously). This is the rotation of 4-6; and sleeve-2. Since the shaft I and the sleeve 2 rotate synchronously, the sleeve 2 does not move along the shaft threads. The load, which is on the hook 5, moves in the longitudinal direction ... If necessary, increase the speed of the load 19, turn off the drive shaft 1. The shaft t stops. The sleeve 2, which continues to rotate from the drive of the sprocket 7 atulkn 3, is screwed along the shaft thread to the left, moving farther from the axis of the roller thrust 5. The diameter of the roller will increase, which will increase its circumferential speed (this position is shown by a dotted line in the drawing). After reaching the desired diameter of the roller, the drive shaft 1 is turned on again, the shaft starts to rotate synchronously with sleeve 2, therefore axial displacement of sleeve 2 along the shaft stops. The load is now moving at a faster speed equal to the peripheral speed of the roller. Reducing the speed of movement of the cargo can be done in two ways. The first way. Do not stop the rotation of the shaft, disconnect the auxiliary drive of the sprocket 7. At the same time, the rotation of the sleeve 3, t g 4 -: - b § the sleeve 2 stops. Sleeve. 2 is screwed by the rotating shaft 1 to the right along the thread of the shaft, and the diameter of the roller decreases. Then turn on the drive of the sleeve 1S S again, the axial displacement of the sleeve 2 stops. The load is moved by the roller at a lower speed. The second way. In this way, the rotation of the sleeve 3 does not stop, the shaft drive I switches to another, increased rotation speed. The shaft ja4HHaeT rotates faster than sleeve 2 and screws it along the thread along the shaft axis to the right. The roller diameter decreases. Then the drive is switched again shaft 1 at the previous speed. Formula of the invention A roller roller assembly containing a drive shaft with a housing mounted on it, molded in the form of a system of hinge bars, of which are attached to bushings, one of which is mounted on the drive shaft with self-braking threads, and ra - free, characterized by the fact that, in order to improve the performance of the roller table, the roller is provided with an additional chain drive, the star of which is rigidly connected to a sleeve freely mounted on the shaft.Sources of information taken into account during the examination: 1.
