ОСУЩЕСТВЛЕНИЕ ИЗОБРЕТЕНИЯ CARRYING OUT THE INVENTION
Заявленное решение относиться к рычажно-резьбовому креплению. На фигуре 1 показана система крепления передней крышки компрессора в разборе, которая включает в себя крышку 2 компрессора, присоединяемую к корпусу 1 компрессора, гайку 3 (обечайку), устанавливаемую на крышку 2 и рычажный элемент, расположенный на гайке 3. The stated solution refers to the lever-threaded fastening. Figure 1 shows a disassembled compressor front cover fastening system, which includes a compressor cover 2 attached to the compressor casing 1, a nut 3 (shell) mounted on the cover 2 and a lever element located on the nut 3.
На крайней радиальной части крышки, ближе к торцу, обращенном в сторону корпуса 1 компрессора и гайки 3, выполнен радиальный паз 11, предназначенный для установки гайки 3, а на самом торце крышки выполнено радиальное уплотнение 19 (уплотнительное кольцо), например, из резины, обеспечивающее дополнительную герметизацию по фланцевому соединению крышки и корпуса. On the extreme radial part of the cover, closer to the end facing the compressor casing 1 and the nut 3, a radial groove 11 is made for installing the nut 3, and at the very end of the cover there is a radial seal 19 (sealing ring), for example, made of rubber, providing additional sealing along the flange connection of the cover and body.
Крайняя часть внутренней поверхности гайки, направленной в сторону крышки, имеет радиальный выступ 12, предназначенный для взаимного соединения с радиальным пазом 11 крышки 2, причем их соединение выполнено подвижным (т.е. гайка может вращаться на крышке) На остальной части внутренней поверхности гайки 3 выполнена
резьба 13. The extreme part of the inner surface of the nut directed towards the cover has a radial protrusion 12 intended for interconnection with the radial groove 11 of the cover 2, and their connection is made movable (i.e. the nut can rotate on the cover) On the rest of the inner surface of the nut 3 completed thread 13.
На торце корпуса 1 компрессора, обращенном в сторону крышки, выполнена резьба 14 взаимосоответствующая резьбе 13 гайки 3. Резьба 13 гайки 3 имеет шаг, соответствующий шагу резьбы 14, выполненной на корпусе 1 компрессора. On the end of the compressor casing 1 facing the cover side, a thread 14 is made corresponding to the thread 13 of the nut 3. The thread 13 of the nut 3 has a pitch corresponding to the pitch of the thread 14 made on the compressor casing 1.
Для затяжки гайки 3, и соответственно крепления крышки 2 к корпусу 1 , используется рычажный элемент, расположенный на внешней поверхности гайки 3, состоящий из соединенных между собой рычага 4, регулирующего элемента 9 и штанги 10. To tighten the nut 3, and, accordingly, fasten the cover 2 to the body 1, a lever element is used, located on the outer surface of the nut 3, consisting of a lever 4, an adjusting element 9 and a rod 10 connected to each other.
Рычаг 4 выполнен, например, преимущественно вытянутой прямоугольной формы, представляет собой две вытянутые параллельные планки, расположенные на расстоянии друг от друга и соединенные между собой по краям более короткими поперечными элементами 5,6, с участками, выходящими за внешние боковые стороны параллельных планок, предназначенными для зацепления с упорами 7,8, выполненными на крышке 2 и на корпусе 1 компрессора. Lever 4 is made, for example, of a predominantly elongated rectangular shape, consists of two elongated parallel strips located at a distance from each other and connected to each other at the edges by shorter transverse elements 5,6, with sections extending beyond the outer lateral sides of the parallel strips intended for engagement with stops 7,8, made on the cover 2 and on the housing 1 of the compressor.
Регулирующий элемент 9 выполнен с внутренней резьбой, служащий, совместно со штангой 10, для регулировки силы затягивания рычага. Регулирующий элемент 9 имеет поперечную ось вращения 17, расположенную на рычаге, преимущественно по его середине. Если точнее, то ось вращения 17 регулирующего элемента может быть установлена в соосных друг другу отверстиях, выполненных в параллельных планках рычага или в дополнительных выступах 15 параллельных планок рычага. The regulating element 9 is made with an internal thread, serving, together with the rod 10, to adjust the tightening force of the lever. The regulating element 9 has a transverse axis of rotation 17 located on the lever, mainly in its middle. More specifically, the axis of rotation 17 of the adjusting element can be installed in holes coaxial to each other, made in the parallel arm strips or in additional projections 15 of the parallel arm strips.
Штанга 10 представляет собой стержень, на одном конце которого выполнена внешняя резьба для соединения с резьбой регулирующего элемента, на втором конце выполнено сквозное отверстие. The rod 10 is a rod, at one end of which an external thread is made for connection with the thread of the regulating element, at the second end a through hole is made.
На внешней поверхности гайки выполнены выступы 18, параллельно расположенные на расстоянии друг от друга, соединенные между собой осью вращения штанги 16, проходящей сквозь отверстие второго конца штанги. Т.е. штанга закреплена на данной оси с возможностью вращения вокруг нее. On the outer surface of the nut there are protrusions 18 located in parallel at a distance from each other, interconnected by the axis of rotation of the rod 16 passing through the hole of the second end of the rod. Those. the rod is fixed on this axis with the possibility of rotation around it.
На боковой стороне крышки выполнены упоры Г -образной формы, расположенные на расстоянии друг от друга и направленные в противоположные друг от друга стороны, причем на боковой стороне корпуса тоже выполнены упоры Г-образной формы, также расположенные на расстоянии друг от друга и направленные в противоположные друг от друга стороны и при этом расположенные параллельно упорам крышки. Упоры крышки и корпуса, направленные в оду сторону, образуют параллельные первые 7 и вторые 8 пары Г-образных упоров, за которые, при затягивании или расслаблении натяжной гайки 3, цепляются первый 5 или второй 6 поперечные элементы рычага (т.е. первая пара упоров, один из которых расположен на крышке, а другой на корпусе, направлена в одну сторону, а вторая пара упоров, один из которых также расположен на крышке, а другой на корпусе, направлена в другую противоположную сторону). L-shaped stops are made on the side of the cover, located at a distance from each other and directed in opposite directions from each other, and on the side of the body, L-shaped stops are also made, also located at a distance from each other and directed in opposite directions sides from each other and at the same time located parallel to the stops. The stops of the cover and the body, directed in one direction, form parallel first 7 and second 8 pairs of L-shaped stops, for which, when tightening or loosening the tension nut 3, the first 5 or second 6 transverse elements of the lever (i.e. the first pair stops, one of which is located on the cover, and the other on the body, is directed in one direction, and the second pair of stops, one of which is also located on the cover, and the other on the body, is directed to the other opposite side).
Работа системы крепления крышки заключается в следующем:
Крышка в собранном виде (т.е. на крышке установлена гайка с резьбой, на гайке установлен рычажный механизм) приставляют к резьбе корпуса компрессора, один конец с поперечным элементом рычага заводят за первую параллельную пару Г -образных упоров крышки и корпуса, путем воздействия силы давят на второй конец рычага (сверху-вниз по часовой стрелке), тем самым рычаг вращаясь вокруг оси первого поперечного элемента, упирающейся в первые выступы на корпусе и крышке, тянет за собой штангу через регулирующий элемент, опускаясь и прижимаясь к поверхности гайки, которая в это время одновременно накручивается на резьбу корпуса и затягивается. За счет увеличенной площади прижимаемых деталей крепления, по сравнению с известными аналогами, обеспечивается дополнительная конструктивная прочность соединения. The work of the cover retention system is as follows: The assembled cover (i.e. a nut with a thread is installed on the cover, a lever mechanism is installed on the nut) is attached to the thread of the compressor housing, one end with the cross member of the lever is wound behind the first parallel pair of L-shaped stops of the cover and housing, by force press on the second end of the lever (top-down clockwise), thereby rotating the lever around the axis of the first transverse element, abutting against the first protrusions on the body and the cover, pulls the rod through the regulating element, dropping and pressing against the surface of the nut, which in this time is simultaneously screwed onto the body thread and tightened. Due to the increased area of the pressed fastening parts, in comparison with the known analogs, additional structural strength of the connection is provided.
Для того чтобы ослабить гайку и снять крышку, необходимо не просто повернуть в обратную сторону рычаг, а в добавок перекинуть его на вторую пару параллельных Г - образных упоров. Т.е. необходимо снизу-вверх, приложив усилие на свободный конец рычага, поднять рычаг, вывести из первой пары Г - образных упоров первый поперечный элемент, расположенный на первом конце рычага, затем повернуть рычаг по оси вращения регулирующего элемента в противоположную сторону, завести второй поперечный элемент второго конца рычага за вторую пару Г - образных упоров корпуса и крышки, приложив усилие сверху-вниз на свободный первый конец рычага, потянуть рычаг против часовой стрелки, тем самым рычаг вращаясь вокруг оси второго поперечного элемента, упирающейся во вторую пару упоров на корпусе и крышке тянет за собой штангу через регулирующий элемент, опускаясь и прижимаясь к поверхности гайки, которая в это время одновременно откручивается с резьбы корпуса и ослабляет свое натяжение, после чего крышка снимается с корпуса компрессора. In order to loosen the nut and remove the cover, it is necessary not only to turn the lever in the opposite direction, but in addition to throw it onto the second pair of parallel L-shaped stops. Those. it is necessary from bottom to top, applying force on the free end of the lever, lift the lever, remove the first transverse element located at the first end of the lever from the first pair of L-shaped stops, then turn the lever along the axis of rotation of the regulating element in the opposite direction, start the second transverse element of the second the end of the lever for the second pair of L-shaped stops of the body and cover, applying force from top to bottom on the free first end of the lever, pull the lever counterclockwise, thereby the lever rotating around the axis of the second transverse element resting on the second pair of stops on the body and the cover pulls behind itself the rod through the regulating element, lowering and pressing against the surface of the nut, which at this time is simultaneously unscrewed from the thread of the housing and loosens its tension, after which the cover is removed from the compressor housing.
Крышка и корпус компрессора могут быть выполнены с оребрением. Упоры на корпусе могут быть выполнены заодно с оребрением корпуса.
The cover and the compressor casing can be made with ribbing. The stops on the body can be made in one piece with the ribbing of the body.
