    A demountable pin for rotatably connecting together two elements of small axial dimension, consisting of a bolt with a frusto-conical under-head and an inner hexagonal through bore for tightening it by a key. The pin is locked between two frusto-conical flares of the elements by an end nut with a frusto-conical under-head and a washer with a frusto-conical surface of greater taper than the flares. The under-heads of the nut and the bolt cooperate with the flares.

    Fig 1
    The invention relates to mechanical engineering and can be used in other branches of the national economy, where reliable connection of parts subjected to alternating loads, in particular in the lever mechanisms of textile machines, is required.
    The purpose of the invention is to increase reliability.
    Figure 1 shows the elements of the joint, a general view; on tfig.2 - the same section; on fig.Z - connection assembly, incision; 4 shows the elements of the connection.
    The joint contains one of the connected parts, made as a plug with cheeks 1 and 2. Holes 3 and 4, respectively, are made in the cheeks by stamping, having surfaces 5 in the form of a truncated cone. Between the cheeks 1 and 2 is placed the second connecting piece 6, having a pivotal bore 3 and 4 bore 7. The bore 7 is equipped with a roller bearing 8, which has an inner ring with a double oppositely directed conical surface 9, the mating surfaces 5 of the bores of the forks. . The connecting element is designed as an axis 10c with an internal hexagonal hole 11 and a thread, nuts 12 and washers 13. The outer surfaces of the head of the axis 14, nuts 15 and washers 16 are tapered.
    The coupling is carried out as follows.
    Between the cheeks 1 and 2 forks install part 6, aligning the holes 3 and 4 forks with hole 7, parts 6, 8 and the combined holes install axis 10 with washer 13 put on it. Screw the nut 12 on the threaded section of the axis. In the process of screwing the washer 13 deforms, choose an angular gap of 2-3 ° between its conical surface and the counter surface of the opening 4 of the cheek 2,
    Performing a collapsible joint axis is constructively simple and economical,
    has axial dimensions that do not extend beyond the dimensions of the plug cheeks, and provides a reliable connection with alternating loads.

    Claims (2)
    [1]
    Claim 1. A split joint axis comprising two connected parts with coaxial holes, one of which is made in
    the shape of a fork, the openings in the cheeks of which are in the shape of truncated cones, with smaller bases facing one towards the other, a bearing is installed in the opening of another part, and a connecting axis placed in the bearing openings and plug cheeks, made in the form of a threaded rod, the ends of which are connected with two elements with conical outer surfaces, the first of which is made
    in the form of a nut placed in the mating hole of one of the plug cheeks, characterized in that, in order to increase reliability, it is provided with a washer made with an outer conical surface and an annular groove on the side of the larger base of the cone, which is formed by the groove and conical surface c has a thickness decreasing to the periphery, the angle of taper of the washer is greater than the angle of taper of the corresponding hole in the fork, the second element with a conical outer surface is made in one piece with the threaded rod, and the washer anovlena between the second tapered surface element and the respective fork opening.
    [2]
    2. The axis according to claim 1, from the fact that the washer with a frusto-conical shape surface is made of high-strength extruded steel.
    3.0cop.1, characterized in that the taper of the washer with the frustoconical shape of the washer exceeds the conicity of the conical holes on
    2-3 °.
