    The invention relates to mechanical engineering and can be used in other fields of national economy for connecting covered and female parts. The purpose of the invention is to increase strength with decreasing dimensions. The sleeves 8 are mounted on the shaft 1, fixed with their end sections in the holes of the drive elements 2 and 3. In the installation zone of the drive elements there are support sleeves 11, 12 and 13, which are hydraulically expanded together with element 1 and the ends of the sleeves 8 in said holes of the drive elements . The latter can be made with a rigid connection connecting two adjacent drive elements. The support sleeve 8 is located in the element 1 and has a length not less than the width of the coupled drive element. 12 hp ff. 3 ilsls

    Claims (13)
    [1]
    The shaft is a continuous tubular element 1, on which individual drive elements 2 and 3 are rigidly fixed, made in the form of cams displaced relative to each other, and the drive element 4. made in the form of two bodies rigidly interconnected 5 and b, representing for example, cams. The rigid connection between bodies 5 and 6 is made in the form of a sleeve 7. Reinforcing sleeves 8 are installed on the shaft between the drive elements, the diameter of which is larger than the diameter of the tubular element 1. The sleeves 8 at the ends in the installation area of the cams 2-4 are made with areas of smaller diameter 9 and 10 and are located in the openings of the drive elements. Two adjacent sleeves 8 with each of the sections 9 are contacted in the opening of the cams 2 and 3. The length of the section 9 is approximately half the width of the cam 2 and 3. The length of the sections 10 of the sleeve 8 located in the hole of the double cam 4 is equal to the width of the bodies 5 and 6. Inward tubular element in the installation area of the drive elements are placed. support sleeves 11-13, hydraulically expanded together with element 1 and sections 9 and 10. Due to the presence of sleeves 11-13, the wall thickness of the tubular element 1 and cylinder 8 can be reduced. The dual cam 4 is made with cavities 14 to reduce its weight or holes 15. The tubular element 1 can be made with slips 16-19 on the outer diameter. The tubular element 1 can be expanded in the area of thickening with the formation of extensions 20, contributing to the shortening of the element 1 and the closer fit of the sleeves 8 to the end surfaces of the drive elements 2 and 3. Between the tubular element 1 and the sleeves 8 are provided annular cavities 21 and 22 connected between a channels 23 for lubrication. Cavities can be filled with damping material 24. Claim 1. Gathering shaft with drive elements, containing a tubular member with specified drive elements rigidly attached to it, is characterized by the fact that, in order to increase strength with decreasing dimensions, the shaft is provided with sleeves fixed between two adjacent drive elements, sleeves
    made step, and one of the steps has a diameter greater than the diameter of the tubular element, and two end steps of the sleeve have an inner diameter equal to the outer diameter of the tubular
    element, and the outer diameter equal to the inner diameter of the drive elements, with steps of smaller diameter rigidly fixed between the tubular element and welded elements.
    [2]
    2. A shaft according to claim 1, in accordance with the fact that between the tubular element and the two drive elements connected by a common connection, the portions of the sleeve with a smaller diameter in the axial direction are equal
    the width of the drive elements, the common connection being a sleeve rigidly connected to each of the drive elements.
    [3]
    3. Val according to claim 1, characterized in that. that areas of the liner with a smaller diameter.
    located between the tubular and the drive elements, in the axial direction are equal to half the width of the drive element, with two adjacent sleeves in contact with the ends of the steps of smaller diameter between the mutually inverted surfaces of the tubular and drive elements.
    [4]
    4. Val on PP. 1-3. characterized in that the outer surface of the sleeves partially protrudes beyond the outer surface of the drive elements having a non-circular shape ..
    [5]
    5. Val on PP. 1-4, characterized in that it is provided with support sleeves,
    placed in a tubular element in the installation zone of the drive elements, the sleeves being longer than the width of the drive elements, and the sleeves themselves are rigidly connected to the tubular element.
    [6]
    6. Val on PP. 1-4. characterized in that the tubular element is made with thickening of the walls on the outer diameter, located in the installation area of the drive
    elements, and the lengths of the thickened zones are greater than the Shirins. drive elements.
    [7]
    7.Val on PP. 1-6, characterized in that the tubular element and the support sleeves are made of steel.
    [8]
    8.Val on PP. 1-7, characterized in that the drive elements are made in the form of cams of cast material.
    [9]
    9.Val on PP. 1-6, about tl and h and yushchi and with. the fact that the liner is made of titanium.
    [10]
    10. Shaft on PP. 1-6, characterized in that the sleeves are made of a carbon-fiber composite material.
    [11]
    ,eleven. Val Lo nn. 1-6. This is due to the fact that the sleeves are made of aluminum.
    [12]
    12, Val on PP. 1-11, which is based on the fact that annular cavities are formed between the tubular element and the sleeves, which are interconnected by channels.
    made in the form of longitudinal grooves on the sleeves, in the transition zone of diameters in contact with the end surfaces of the drive elements.
    [13]
