Definitions
- the utility model relates to the field of transport engineering and can be applied in high-speed transmission shafts of a power transmission with hinges of equal angular speeds, moving in the axial direction.
- An analogue of the technical solution is a high-speed joint of equal angular velocity, containing a corrugated cover installed by a section of a larger diameter on the hinge body, and a section of a smaller diameter on the shaft.
- the corrugated cover contains two sections of corrugations, which are interconnected by a reinforced section to give strength to the cover in order to prevent excessive inflation in the middle part at high revolutions of the hinge.
- the corrugation connected to the portion of the larger diameter of the cover is made with an outer diameter exceeding the outer diameter of the hinge body.
- a known joint of equal angular velocity with a corrugated cover of a high-speed transmission shaft comprises a corrugated portion connected to sections of larger and smaller diameters mounted on the hinge and shaft body. A portion of a smaller diameter of the cover is connected to the corrugated portion by means of a radially inactive element. A section of a larger diameter of the cover is connected to the corrugated section by means of a radially inactive element. Corrugated section contains two corrugation, and each of the corrugations is made with an outer diameter not exceeding 0.058 m, on each of the hollows of the cover there is an amplifying tide facing the shaft (see patent RU N ° 2216661, MPK 7 F16C11 / 06, 2003).
- the disadvantage of this design is a significant deformation of the corrugations during axial movement of the shaft, which ultimately leads to a decrease in the reliability and durability of the cover and the hinge of the transmission shaft as a whole.

- the disadvantages of the technical solution are: the work of the cover with kinks and increased friction between the corrugations when using equal speed angular speeds on the hinges, since the hinges have the possibility of axial movement of its components - the housing and the shaft, as a result of factors such as a large angle of inclination forming one of the walls of each corrugation; the possibility of increased noise when the shaft and the hinge wall are in contact.
- a disadvantage of the known device is that in order to exclude significant movement of the shaft and the hinges relative to each other, two types of hinges of equal angular velocities of the movable and fixed types are used, which creates inconvenience during installation and does not allow using the fully high-speed capabilities of the hinge of the movable type.
- a disadvantage of the known device is that the drive shaft has a complex structure, and to prevent axial movement of the shaft, one of its ends is fixed in one of the hinge clips, which also complicates the design.
- a drive shaft of a vehicle comprising kinematically connected with the ends of the shaft hinges of equal angular speeds of a movable type and corrugated covers, each of which is connected to the hinge body and the shaft by sections of larger and smaller diameters, respectively, by means of axially inactive components, the shaft being made with its limitation longitudinal movement, (see German patent Ne 2927648, IPC 2 F16D 3/84, 1981) This decision is made as a prototype.
- the technical problem solved by the utility model: simplifying the design of the drive shaft while limiting the longitudinal mobility of the shaft, reliability, durability of the cover and the drive shaft hinge in general at high speeds.
- the problem is solved due to the fact that in the known drive shaft of the vehicle, which contains kinematically connected to the ends of the shaft hinges of equal angular velocities of the movable type and corrugated covers, each of which is connected to the hinge body and the shaft with sections of larger and smaller diameters, respectively, by means of semitransparent axial the direction of the elements, in accordance with the utility model, the corrugated covers have no more than two corrugations and are connected to the shaft and the hinge so that the distance between th larger diameter portion and a smaller diameter cover in the operating position of the drive shaft exceeds the specified distance between sections of the cover in a static state.
- Axially inactive elements of the cover are additionally fixed with clamps.
- the case is equipped with an annular insert that limits the axial movement of the hinge rollers.
- the technical result from the use of the utility model is that the execution of each corrugated cover with two corrugations and installed so that the distance between the section of a larger diameter and the section of a smaller diameter of the corresponding cover in the working position of the drive shaft exceeds the length of the cover in a static state, while ensuring the necessary drive shaft mobility to prevent critical longitudinal shaft movements and stabilize its operation.
- Figure 1 drive shaft with hinges and mounted on it corrugated covers, a longitudinal section.
- FIG. 2 is a view A of FIG. 1 on an enlarged scale.
- the high-speed drive shaft 1 is provided with symmetrical and kinematically connected hinges 2 of equal angular velocities of a movable type.
- the hinges 2 are protected by corrugated covers 3.
- Each of the covers 3 contains a corrugated section 4, consisting of two corrugations 4A, 4B.
- Each of the corrugations 4A, 4B is made with a specific outer diameter. A greater number of corrugations leads to an unjustified increase in the wall thickness of the cover in order to create a static stress state of the cover.
- Each of the covers 3 is connected to the housing 5 of the corresponding hinge 2 and the shaft 1 by sections of larger diameters and smaller diameters, respectively, by means of axially inactive ones elements 6.
- the immobility in the axial direction of the elements 6 is ensured by the fact that they are increased in size (have walls of greater thickness than the corrugations), are installed with an interference fit on the body 5 of the hinge 2 and on the shaft 1 and secured by additional devices, for example, clamps 7.
- a reinforcing casing 8 is installed behind the cover, additionally pressing the cover 1 to the hinge body 5 2.
- the cover 1 is equipped with an annular insert 9 installed in the cover with an interference fit, which is additionally pressed against the hinge body 5 by the cover 8.
- the hinge 2 comprises a hollow body 5 having raceways on an inner cylindrical surface. Inside the housing there is a shaft 1 with a clip 10 fixed on it, on which raceways are also made. The balls 11 located in the raceways are installed in the windows of the separator 12. An annular insert 9 installed in the cover 3 limits the axial movement of the balls 11 of the hinge 2 and prevents them from falling out of the housing 5 during axial displacement of the shaft 1.
- Corrugated case 3 is mounted on the shaft 1 and the hinge 2 in a stressed state (i.e. there is a spring effect). This effect is achieved due to the fact that in the working position of the shaft 1, the distance between the cover section For a larger diameter located on the hinge body 2 and the cover section Sv of a smaller diameter located on the shaft 1 is greater than the specified distance in the static position of the cover 3, that is, the cover stretched along its axis.
- the drive shaft and its elements can be manufactured using existing process equipment. Usage example.
- the hinges 2 are assembled with the shaft 1. Due to the mobility of the hinges 2 on the shaft 1, the hinges are moved along the shaft to its center and put on the open part of the hinge the 2nd section of the cover with the casing 8 installed on it, securing them with the clamp 7. When assembling, the distance between the sections of the cover of the larger Za and the smaller Sv diameters is equal to the size of the cover 3 in a static position. Next, the assembled shaft is installed on the car. When installing the shaft, the hinges 2 are moved along the shaft from the center to the periphery, stretching the covers 3 to a stressed state and increasing the distance between the sections Za and Zv of the cover.
- Corrugated cover 3 provides reliable protection of the hinge 2 from harmful factors (dirt, moisture, etc.) of the external environment in the entire range of operational characteristics of the high-speed drive shaft.
- An additional advantage of the proposed solution is that it increases the resistance of the cover to radial tearing. It was found that when the shaft 1 rotates with revolutions close to the nominal, there is a tendency to “inflate” the cover 3 from the action of centrifugal forces, i.e. corrugations 4a and 4c tend to open, which is aggravated by the presence of lubricant in their cavities, an increase in temperature from friction of the corrugations during operation of the hinge, as well as the movement (compression, stretching) of the corrugations, if the hinge is movable in the axial direction. This can lead to loss of stability of the cover 3 as a whole and its rupture.

Аналогом технического решения является быстроходный шарнир равной угловой скорости, содержащий гофрированный чехол, установленный участком большего диаметра на корпусе шарнира, а участком меньшего диаметра - на валу. Гофрированный чехол содержит два участка гофр, которые связаны между собой армированным участком для придания чехлу прочности с целью предотвращения излишнего его раздувания в средней части при больших оборотах шарнира. Гофр, соединенный с участком большего диаметра чехла, выполнен с наружным диаметром, превышающим наружный диаметр корпуса шарнира. Обе стенки каждого гофра чехла выполнены почти параллельно друг другу, а одна из стенок гофра наименьшего наружного диаметра выполнена с плавным переходом ее в участок меньшего диаметра чехла, которым он установлен на валу (см. заявку PCT 93/06379, MПK 6 F16D 3/84, публикация 01.04.93 г.).An analogue of the technical solution is a high-speed joint of equal angular velocity, containing a corrugated cover installed by a section of a larger diameter on the hinge body, and a section of a smaller diameter on the shaft. The corrugated cover contains two sections of corrugations, which are interconnected by a reinforced section to give strength to the cover in order to prevent excessive inflation in the middle part at high revolutions of the hinge. The corrugation connected to the portion of the larger diameter of the cover is made with an outer diameter exceeding the outer diameter of the hinge body. Both walls of each corrugation cover are made almost parallel to each other, and one of the walls of the corrugation of the smallest outer diameter is made with its smooth transition into the section of the smaller diameter of the cover with which it is mounted on the shaft (see PCT application 93/06379, MPK 6 F16D 3/84 publication 04/01/93).
Недостатком такой конструкции является значительная деформация гофр при осевом перемещении вала, что в конечном итоге приводит к снижению надежности и долговечности чехла и в целом шарнира трансмиссионного вала.The disadvantage of this design is a significant deformation of the corrugations during axial movement of the shaft, which ultimately leads to a decrease in the reliability and durability of the cover and in general the hinge of the transmission shaft.
Известен шарнир равной угловой скорости с гофрированный чехлом быстроходного трансмиссионного вала. Чехол содержит гофрированный участок, соединенный с установленными на корпусе шарнира и вала участками большего и меньшего диаметров. Участок меньшего диаметра чехла соединен с гофрированным участком посредством малоподвижного в радиальном направлении элемента. Участок большего диаметра чехла соединен с гофрированным участком посредством малоподвижного в радиальном направлении элемента. Гофрированный участок содержит два
гофра, причем каждый из гофр выполнен с наружным диаметром, не превышающим 0,058 м, на каждой же из впадин чехла выполнен усилительный прилив, обращенный к валу (см. патент RU N°2216661 ,MПK 7 F16C11/06, 2003 г.). Недостатком такой конструкции является значительная деформация гофр при осевом перемещении вала, что в конечном итоге приводит к снижению надежности и долговечности чехла и в целом шарнира трансмиссионного вала.A known joint of equal angular velocity with a corrugated cover of a high-speed transmission shaft. The cover comprises a corrugated portion connected to sections of larger and smaller diameters mounted on the hinge and shaft body. A portion of a smaller diameter of the cover is connected to the corrugated portion by means of a radially inactive element. A section of a larger diameter of the cover is connected to the corrugated section by means of a radially inactive element. Corrugated section contains two corrugation, and each of the corrugations is made with an outer diameter not exceeding 0.058 m, on each of the hollows of the cover there is an amplifying tide facing the shaft (see patent RU N ° 2216661, MPK 7 F16C11 / 06, 2003). The disadvantage of this design is a significant deformation of the corrugations during axial movement of the shaft, which ultimately leads to a decrease in the reliability and durability of the cover and the hinge of the transmission shaft as a whole.
Известен шарнир равных угловых скоростей подвижного типа, содержащий защитный чехол с гофрированным участком, соединенным с установочными участками большего и меньшего диаметра, предназначенными для установки на корпус подвижного шарнира и вала соответственно (см. патент РФ N°28747 U, МПК 7 F16C11/06, 2003 г.).Known hinge of equal angular velocities of a movable type, comprising a protective case with a corrugated portion connected to mounting sections of a larger and smaller diameter, designed to be mounted on a housing of a movable hinge and shaft, respectively (see RF patent N ° 28747 U, IPC 7 F16C11 / 06, 2003).
Недостатками технического решения являются: работа чехла с перегибами и повышенным трением между гофрами при использование на шарнирах равных угловых скоростей подвижного типа, т.к. шарниры имеют возможность осевого перемещения его составляющих - корпуса и вала, в результате таких факторов, как большого угла наклона образующих одной из стенок каждого гофра; возможность повышенного шума при соприкосновении вала и стенки шарнира.The disadvantages of the technical solution are: the work of the cover with kinks and increased friction between the corrugations when using equal speed angular speeds on the hinges, since the hinges have the possibility of axial movement of its components - the housing and the shaft, as a result of factors such as a large angle of inclination forming one of the walls of each corrugation; the possibility of increased noise when the shaft and the hinge wall are in contact.
Известен привод управляемого колеса, содержащий вал, на шлицевых концах хвостовых частей которого неподвижно закреплены шарниры равных угловых скоростей, внутренние полости которых защищены грязезащитными устройствами, закрепленными посадочными частями посредством хомутов на посадочных участках хвостовых частей вала и на корпусах шарниров (см. патент РФ NQ65431 U, МПК 8 B60K 17/30, 2007 г.).Known drive wheel drive containing a shaft, at the splined ends of the tail parts of which are fixedly fixed hinges of equal angular velocities, the internal cavities of which are protected by anti-dust devices, fixed by mounting parts by means of clamps on the landing sections of the shaft tail parts and on the hinge bodies (see RF patent NQ65431 U IPC 8 B60K 17/30, 2007).
Недостатком известного устройства является то, что с целью исключения значительного перемещения вала и шарниров относительно друг друга используется два типа шарниров равных угловых скоростей подвижного и неподвижного типов, что создает неудобства при монтаже и не позволяет использовать полностью высокоскоростные возможности шарнира подвижного типа.A disadvantage of the known device is that in order to exclude significant movement of the shaft and the hinges relative to each other, two types of hinges of equal angular velocities of the movable and fixed types are used, which creates inconvenience during installation and does not allow using the fully high-speed capabilities of the hinge of the movable type.
Известен приводной вал транспортного средства, содержащий
кинематически связанные с концами вала два шарнира равных угловых скоростей подвижного типа с установленными на шарнирах гофрированными чехлами (см. патент РФ NQ2027923, MПK 6 F16DЗ/26, 1995 Г.).Known drive shaft of a vehicle containing kinematically connected with the ends of the shaft, two hinges of equal angular velocities of the movable type with corrugated covers mounted on the hinges (see RF patent NQ2027923, MPK 6 F16DZ / 26, 1995).
Недостатком известного устройства является то, что приводной вал имеет сложную конструкцию, а для предотвращения осевого перемещения вала один из его концов фиксируют в одной из обойм шарниров, что также усложняет конструкцию.A disadvantage of the known device is that the drive shaft has a complex structure, and to prevent axial movement of the shaft, one of its ends is fixed in one of the hinge clips, which also complicates the design.
Известен приводной вал транспортного средства, содержащий кинематически связанные с концами вала шарниры равных угловых скоростей подвижного типа и гофрированные чехлы, каждый из которых соединен с корпусом шарнира и валом участками большего и меньшего диаметров соответственно посредством малоподвижных в осевом направлении элементов, причем вал выполнен с ограничением его продольного перемещения, (см. патент Германии Ne 2927648, МПК 2 F16D 3/84, 1981 г.) Данное решение принято за прототип.A drive shaft of a vehicle is known comprising kinematically connected with the ends of the shaft hinges of equal angular speeds of a movable type and corrugated covers, each of which is connected to the hinge body and the shaft by sections of larger and smaller diameters, respectively, by means of axially inactive components, the shaft being made with its limitation longitudinal movement, (see German patent Ne 2927648, IPC 2 F16D 3/84, 1981) This decision is made as a prototype.
Недостатком данного решения является сложность конструкции, наличие дополнительных элементов (пружин), обеспечивающих ограничение продольного перемещения вала.The disadvantage of this solution is the complexity of the design, the presence of additional elements (springs), providing a limitation of the longitudinal movement of the shaft.
Техническая задача. Задача, решаемая полезной моделью: упрощение конструкции приводного вала при обеспечении ограничения продольной подвижности вала, надежности, долговечности чехла и в целом шарнира приводного вала при высоких оборотах.The technical problem. The problem solved by the utility model: simplifying the design of the drive shaft while limiting the longitudinal mobility of the shaft, reliability, durability of the cover and the drive shaft hinge in general at high speeds.
Поставленная задача решается за счет того, что в известном приводном вале транспортного средства, содержащем кинематически связанные с концами вала шарниры равных угловых скоростей подвижного типа и гофрированные чехлы, каждый из которых соединен с корпусом шарнира и валом участками большего и меньшего диаметров соответственно посредством малоподвижных в осевом направлении элементов, в соответствии с полезной моделью гофрированные чехлы имеют не более двух гофр и соединены с валом и шарниром таким образом, что расстояние между участком большего диаметра и участком меньшего диаметра чехла в рабочем положении приводного вала превышает указанное расстояние между
участками чехла в статическом состоянии.The problem is solved due to the fact that in the known drive shaft of the vehicle, which contains kinematically connected to the ends of the shaft hinges of equal angular velocities of the movable type and corrugated covers, each of which is connected to the hinge body and the shaft with sections of larger and smaller diameters, respectively, by means of semitransparent axial the direction of the elements, in accordance with the utility model, the corrugated covers have no more than two corrugations and are connected to the shaft and the hinge so that the distance between th larger diameter portion and a smaller diameter cover in the operating position of the drive shaft exceeds the specified distance between sections of the cover in a static state.

Технический результат от использования полезной модели заключается в том, что выполнение каждого гофрированного чехла с двумя гофрами и установленным так, что расстояние между участком большего диаметра и участком меньшего диаметра соответствующего чехла в рабочем положении приводного вала превышает длину чехла в статическом состоянии, позволяет при обеспечении необходимой подвижности приводного вала предотвратить критические продольные перемещения вала и стабилизировать его работу.The technical result from the use of the utility model is that the execution of each corrugated cover with two corrugations and installed so that the distance between the section of a larger diameter and the section of a smaller diameter of the corresponding cover in the working position of the drive shaft exceeds the length of the cover in a static state, while ensuring the necessary drive shaft mobility to prevent critical longitudinal shaft movements and stabilize its operation.
Кроме того, такая конструкция вала в сборе с чехлом и шарниром проста и технологична в изготовлении и при сборке, поскольку количество деталей сведено к разумному минимуму, отсутствуют сложные детали, при этом обеспечивается ограниченная подвижность вала, долговечность чехла и шарнира.In addition, this design of the shaft assembly with a cover and a hinge is simple and technologically advanced in manufacturing and during assembly, since the number of parts is minimized, there are no complex parts, while providing limited shaft mobility, durability of the cover and hinge.

Вариант осуществления заявленного изобретения.An embodiment of the claimed invention.
Быстроходный приводной вал 1 снабжен расположенными симметрично и кинематически связанными с ним шарнирами 2 равных угловых скоростей подвижного типа. Шарниры 2 защищены гофрированными чехлами 3. Каждый из чехлов 3 содержит гофрированный участок 4, состоящий из двух гофр 4а, 4в. Каждый из гофр 4а, 4в выполнен с определенным наружным диаметром. Большее количество гофр ведет к неоправданному увеличению толщины стенок чехла с целью создания статического напряженного состояния чехла.The high-speed drive shaft 1 is provided with symmetrical and kinematically connected hinges 2 of equal angular velocities of a movable type. The hinges 2 are protected by corrugated covers 3. Each of the covers 3 contains a corrugated section 4, consisting of two corrugations 4A, 4B. Each of the corrugations 4A, 4B is made with a specific outer diameter. A greater number of corrugations leads to an unjustified increase in the wall thickness of the cover in order to create a static stress state of the cover.
Каждый из чехлов 3 соединен с корпусом 5 соответствующего шарнира 2 и валом 1 участками большего За и меньшего Зв диаметров соответственно посредством малоподвижных в осевом направлении
элементов 6. Малоподвижность в осевом направлении элементов 6 обеспечивается тем, что, они увеличены в размерах (имеют стенки большей толщины, чем гофры), установлены с натягом на корпусе 5 шарнира 2 и на валу 1 и закреплены дополнительными устройствами, например, хомутами 7. Со стороны участка большего диаметра За чехла установлен усиливающий кожух 8 дополнительно прижимающий чехол 1 к корпусу 5 шарнира 2. Чехол 1 снабжен кольцевой вставкой 9, установленной в чехле с натягом, которая дополнительно прижимается к корпусу 5 шарнира 2 кожухом 8. Шарнир 2 содержит полый корпус 5, имеющий дорожки качения на внутренней цилиндрической поверхности. Внутри корпуса расположен вал 1 с неподвижно закрепленной на нем обоймой 10, на которой также выполнены дорожки качения. Расположенные в дорожках качения шарики 11 установлены в окнах сепаратора 12. Кольцевая вставка 9, установленная в чехле 3, ограничивает осевое перемещение шариков 11 шарнира 2 и предотвращает их выпадение из корпуса 5 при осевом смещении вала 1.Each of the covers 3 is connected to the housing 5 of the corresponding hinge 2 and the shaft 1 by sections of larger diameters and smaller diameters, respectively, by means of axially inactive ones elements 6. The immobility in the axial direction of the elements 6 is ensured by the fact that they are increased in size (have walls of greater thickness than the corrugations), are installed with an interference fit on the body 5 of the hinge 2 and on the shaft 1 and secured by additional devices, for example, clamps 7. On the side of the larger diameter section, a reinforcing casing 8 is installed behind the cover, additionally pressing the cover 1 to the hinge body 5 2. The cover 1 is equipped with an annular insert 9 installed in the cover with an interference fit, which is additionally pressed against the hinge body 5 by the cover 8. The hinge 2 comprises a hollow body 5 having raceways on an inner cylindrical surface. Inside the housing there is a shaft 1 with a clip 10 fixed on it, on which raceways are also made. The balls 11 located in the raceways are installed in the windows of the separator 12. An annular insert 9 installed in the cover 3 limits the axial movement of the balls 11 of the hinge 2 and prevents them from falling out of the housing 5 during axial displacement of the shaft 1.
Гофрированный чехол 3 установлен на валу 1 и шарнире 2 в напряженном состоянии (т.е. имеется эффект пружинения). Данный эффект достигается за счет того, что в рабочем положении вала 1 расстояние между участком чехла За большего диаметра, расположенном на корпусе шарнира 2 и участком чехла Зв меньшего диаметра, расположенном на валу 1 , больше указанного расстояния в статическом положении чехла 3, то есть чехол растянут вдоль своей оси. Приводной вал и его элементы могут быть изготовлены с использованием существующего технологического оборудования. Пример использования.Corrugated case 3 is mounted on the shaft 1 and the hinge 2 in a stressed state (i.e. there is a spring effect). This effect is achieved due to the fact that in the working position of the shaft 1, the distance between the cover section For a larger diameter located on the hinge body 2 and the cover section Sv of a smaller diameter located on the shaft 1 is greater than the specified distance in the static position of the cover 3, that is, the cover stretched along its axis. The drive shaft and its elements can be manufactured using existing process equipment. Usage example.
Сборка и установка вала осуществляется в следующей последовательности. На каждый конец вала 1 устанавливают чехлы 3 и закрепляют участокAssembly and installation of the shaft is carried out in the following sequence. At each end of the shaft 1, covers 3 are installed and a section is fixed
Зв меньшего диаметра чехла 3 хомутом 7 в месте его рабочего положения. Затем производят сборку шарниров 2 с валом 1. За счет подвижности шарниров 2 на валу 1 , шарниры перемещают вдоль вала к его центру и
надевают на открытую часть шарнира 2 участок За чехла с установленным на нем кожухом 8, закрепляя их посредством хомута 7. При сборке расстояние между участками чехла большего За и меньшего Зв диаметров равно размеру чехла 3 в статическом положении. Далее собранный вал устанавливают на автомобиле. При установке вала шарниры 2 перемещают вдоль вала от центра к периферии, растягивая чехлы 3 до напряженного состояния и увеличивая расстояние между участками За и Зв чехла.Sv of a smaller diameter of the cover 3 with a clamp 7 in the place of its working position. Then, the hinges 2 are assembled with the shaft 1. Due to the mobility of the hinges 2 on the shaft 1, the hinges are moved along the shaft to its center and put on the open part of the hinge the 2nd section of the cover with the casing 8 installed on it, securing them with the clamp 7. When assembling, the distance between the sections of the cover of the larger Za and the smaller Sv diameters is equal to the size of the cover 3 in a static position. Next, the assembled shaft is installed on the car. When installing the shaft, the hinges 2 are moved along the shaft from the center to the periphery, stretching the covers 3 to a stressed state and increasing the distance between the sections Za and Zv of the cover.
При работе и соответственно возможном осевом смещении вала 1 в любую сторону чехлы 3, находящиеся в напряженном состоянии (т.е. создающие эффект пружинения) оказывают сопротивление перемещению вала - возвращая его в исходное положение. Чехлы 3 удерживают вал в исходном положении усилием сжатия (для вала усилием растяжения).During operation and, accordingly, the possible axial displacement of the shaft 1 in any direction, the covers 3, which are in a stressed state (i.e., create the effect of springing), resist the movement of the shaft - returning it to its original position. Cases 3 hold the shaft in its original position by compressive force (for the shaft by tensile force).
Гофрированный чехол 3 обеспечивает надежную защиту шарнира 2 от вредно влияющих факторов (грязь, влага и т.д.) внешней среды во всем диапазоне эксплуатационных характеристик быстроходного приводного вала.Corrugated cover 3 provides reliable protection of the hinge 2 from harmful factors (dirt, moisture, etc.) of the external environment in the entire range of operational characteristics of the high-speed drive shaft.
Дополнительным преимуществом заявляемого решения является то, что повышается устойчивость чехла к радиальному разрыву. Установлено, что при вращении вала 1 с оборотами, близкими к номинальным, имеется тенденция к "раздуванию" чехла 3 от действия центробежных сил, т.е. гофры 4а и 4в стремятся раскрыться, что усугубляется наличием в их полостях смазки, увеличением температуры от трения гофр при работе шарнира, а также перемещением (сжатием, растяжением) гофр, в случае, если шарнир является подвижным в осевом направлении. Это может привести к потере устойчивости чехла 3 в целом и его разрыву. Выполнение заявляемой конструкции приводного вала с установкой чехлов 3 в напряженном состоянии, с определенным количеством гофр (один или два гофра), а также определенное конструктивное выполнение малоподвижных в радиальном направлении элементов 6 и наличие кожуха 8 предотвращает как осевое смещение вала до возможного контакта с шарниром, так и "раздувание" чехла при вращении вала 3 с оборотами, близкими к номинальным, и обеспечивает надежность, долговечность чехла и в целом шарнира трансмиссионного вала, а также упрощает конструкцию приводного вала по сравнению с конструкцией приводного вала прототипа.
An additional advantage of the proposed solution is that it increases the resistance of the cover to radial tearing. It was found that when the shaft 1 rotates with revolutions close to the nominal, there is a tendency to “inflate” the cover 3 from the action of centrifugal forces, i.e. corrugations 4a and 4c tend to open, which is aggravated by the presence of lubricant in their cavities, an increase in temperature from friction of the corrugations during operation of the hinge, as well as the movement (compression, stretching) of the corrugations, if the hinge is movable in the axial direction. This can lead to loss of stability of the cover 3 as a whole and its rupture. The implementation of the inventive design of the drive shaft with the installation of covers 3 in a stressed state, with a certain number of corrugations (one or two corrugations), as well as a certain structural design of the radially inactive elements 6 and the presence of a casing 8 prevents axial displacement of the shaft until it can come into contact with the hinge, as well as the "inflation" of the cover during rotation of the shaft 3 with revolutions close to the nominal, and ensures the reliability, durability of the cover and the hinge of the transmission shaft as a whole, and also simplifies the design when water shaft in comparison with the design of the drive shaft of the prototype.
