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.
  • 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).
  • 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.
