    In a drive shaft assembly particularly for agricultural implements, a pair of telescoping tubes which may be placed in torque transmitting engagement with each other are provided with a profiled hub on the outer tube at the end thereof where the inner tube is inserted, with the profiled hub consisting essentially of formed inserts in a number corresponding to a number of ribs provided on the inner tube, with contact faces being provided on both sides of the inserts in the circumferential direction to correspond to the shape of the ribs, the insert being held in rotationally fixed engagement with the outer tube.

    专利说明:

    The invention relates to mechanical engineering and can be used, for example, to connect the drive shaft of agricultural machines to the tractor's power take-off shaft.
    The purpose of the invention is to improve the manufacturability and assembly while reducing the cost of the device as a whole.
    Figure 1 shows a device with two shaped liners, a cross-section; Fig. 2 shows a circumferential tube with three shaped liners, a cross section, an embodiment; Fig. 3 shows a circumferential pipe, the end face of which inserts are made of a screw, longitudinal section, an embodiment; in FIG. 4 — a circumferential tube, the end of the liners of which is formed by two surfaces converging to the longitudinal axis of symmetry of the liners, a longitudinal section, an embodiment; FIG. 3 shows an embodiment of devices with the location of inserts in an intermediate connecting element.
    The device contains at least two telescopically connected pipes 1 and with means for transmitting a torque between them. These funds on the male pipe 2 are made in the form of radially directed longitudinal ribs 3, and on the female pipe 1 in the form of reciprocal cavities 4 formed by mutually reversed side surfaces of the shaped liners 5, which are made in the form of ring sectors that are rigidly fixed on the inner surface - neck pipe 1. Shaped inserts can be made by any known method, for example, forging, stamping, pressing from powders. Due to the small amount of material required for liners, more expensive materials can be used that have improved physicomechanical properties with respect to the pipe material without increasing or even reducing the cost of the device as a whole. The attachment to the surface of the pipe 1 can also be carried out by any known means including gluing, welding or by means of threaded elements. The number of shaped inserts 5 in the device corresponds to the number of ribs 3 and is selected by calculation.
    based on the magnitude of the torque generated.
    The following design options are provided for the device:
    - one of the ends of each insert 5 may be formed by converging
    to the longitudinal axis of symmetry of the insert 6 surfaces (Fig. 4); This implementation allows to automate the process of joining elements 1 and 2 due to the spontaneous orientation of the latter in the circumferential direction with relative axial movement;
    - one of the ends of each liner can be formed by a screw surface, and the direction of this surface for each insert is the same (Fig. 3), while the direction of the screw surface opposite to the direction of rotation does not reduce the area of the mating surfaces of the elements transmitting the torque;
    - the face surfaces of the insert can be displaced in the axial direction relative to the end of the pipe 1 located on the side of the last part (FIG. 4), which allows for the centering of the pipes 1 and 2 before their connection, simplifies the assembly process;
    -the device can be equipped with an intermediate connecting element 8, made in the form of a hollow cylinder rigidly connected to one of the pipes, and the insert is located inside the specified connecting element 8, with the device being differentiated and then connected to any shaft connected to it. funds;
    The gripping pipe 1 may be surrounded by a protective casing 9 with a feed in funnel 10.
    The expediency of using one or another variant, as well as their combinations, is determined by the specific conditions of operation of the device.
    The device works as follows.
    To connect the shafts, an axial movement of, for example, pipe 1 in the direction of the pipe 2 is carried out to ensure the interaction of the working surfaces of the coupling elements of the pipes. The center of this operation is the transmission of torque between the connected shafts.
