Изобретение относитс к машиностроению и может быть использовано в различных агрегатах, содержащих передачи с гибкой св зью.The invention relates to mechanical engineering and can be used in various aggregates containing flexible coupling transmissions.
Известно нат жное устройство передач с гибкой св зью, содержаш,ее корпус, установленный в корпусе шток, св занный, с нат жным элементом, воздействуюш,ую на шток 1 установленную соосно с последним рабочую пружину сжати , механизм фиксации штока и пружинный демпфер.A flexible tensioning gear device is known to contain its body, a stem mounted in the body, associated with a tensioning element acting on the rod 1 mounted coaxially with the last compression spring, the stem locking mechanism and the spring damper.
Механизм фиксации жестко закреплен в корпусе, а пружинный демпфер расположен в теле штока 1 .The locking mechanism is rigidly fixed in the housing, and the spring damper is located in the body of the rod 1.
Недостатками данного устройства вл ютс мала величина хода нат жного элемента и непосто нство усили нат жени .The disadvantages of this device are the small value of the tension of the tension element and the inability of the tension force.
Цель изобретени - расширение функциональных возможностей нат жного устройства путем увеличени хода штока с нат жным элементом.The purpose of the invention is to enhance the functionality of the tensioning device by increasing the stroke of the rod with the tensioning element.
Поставленна цель достигаетс тем, что в нат жном устройстве передач с гибкой св зью, содержащем корпус, установленный в корпусе шток, св занный с нат ж-ным элементом, воздействующую на штокThe goal is achieved by the fact that, in a tensioning device, transmissions with a flexible coupling, comprising a housing, a stem mounted in the housing, coupled with a tension element, acting on the stem
и установленную соосно с последним рабочую пружину сжати , механизм фиксации штока и пружинный де.мпфер, механизм фиксации штока выполнен в виде подвижных в осевом направлении клиньев, 5 взаимодействующих с рабочей пружиной сжати , охватывающей клинь обоймы и расклинивающего узла, а пружинный демпфер установлен между корпусом и обоймой.and a compression spring installed coaxially with the latter, a stem locking mechanism and a spring damper, a stem locking mechanism is made in the form of axially movable wedges, 5 interacting with a compressive operating spring covering the wedge of the yoke and a proppant, and a spring damper is installed between the body and clip.
На чертеже изображено нат жное уст10 ройство, общий вид, осевой разрез.The drawing shows a tension device, a general view, an axial section.
Устройство содержит корпус 1, установленный в корпусе 1 шток 2, св занный с нат жным элементом 3, рабочую пружину 4 сжати , воздействующую на шток 2, и установленный соосно с ним механизм 5 фиксации щтока 2, содержащий подвижные в осевом направлении клинь 6, взаимодействующие с рабочей пружиной сжати , охватываемые обоймой 7, и расклинивающий узел 8, состо щий из втулки 9, 20 взаимодействующих с ней щтанг 10, воздействующей на последние гайки 11 и резьбовой втулки 12. Между корпусом 1 и обоймой 7 установлен пружинный демпфер 13, обеспечивающий кроме гашени колебаний гибкой св зи прижатие обоймы 7 к клинь м 6.The device comprises a housing 1, a rod 2 mounted in the housing 1, connected with the tension element 3, a compression spring 4 acting on the rod 2, and a clamping mechanism 5 of the shaft 2 which is axially movable and interacting with a compression spring, covered by a yoke 7, and a wedging unit 8, consisting of a sleeve 9, 20 interacting with it, a bolt 10, acting on the last nuts 11 and a threaded sleeve 12. A spring damper 13 is installed between the case 1 and the yoke 7, providing besides quenching the vibrations of the flexible connection, pressing the holder 7 against the wedge m 6.
В корпусе 1 установлена ограничительна втулка 14, охватывающа шток 2.In the housing 1 there is a limiting sleeve 14, which covers the stem 2.
Устройство работает следующим образом .The device works as follows.
Рабоча пружина 4 сжати воздействует на клинь 6 механизма 5 фиксации и упирает их обойму 7, вследствие чего происходит заклинивание щтока 2 и смещение его в направлении нат жени . Нат жение происходит до упора клиньев 6 в ограничительную втулку 14. При необходимости дальнейщего нат жени посредством гайки 11, штанг 10 и втулки 9 воздействуют на обойму 7, производ расклинивание щтока 2, и перемещают последний в направлении нат жени на требуемое рассто ние. Расклинивающий узел 8 при этом удерживаетс ot смещени за счет соединени гайки 11 с резьбовой втулкой 12. После перемещени штока 2 на требуемое рассто ние механизм 5 фиксации вновь соедин етс со штоком 2, и рабоча пружина 4 сжати , воздейству на последний, осуществл ет нат жение. 1 I ТThe compression spring 4 acts on the wedge 6 of the fixing mechanism 5 and rests against the clip 7, resulting in the wedging of the brush 2 and its displacement in the direction of tension. Tensioning takes place all the way against the wedges 6 into the limiting sleeve 14. If further tension is necessary, by means of the nut 11, the rods 10 and the sleeves 9, act on the yoke 7, wedging the rod 2, and moving the latter in the direction of tension for the required distance. The proppant unit 8 is kept ot offset by connecting the nut 11 with the threaded sleeve 12. After the rod 2 is moved for the required distance, the fixing mechanism 5 is again connected to the rod 2, and the compression spring 4 acts on the latter . 1 I T
Использование изобретени позвол ет сократить габариты устройства и повысить надежность нат жени гибкой св зи.The use of the invention makes it possible to reduce the dimensions of the device and to increase the reliability of the tension of the flexible connection.
