    A support structure for a crosshead slide bearing of a reciprocating engine, comprising a frame (1) having a pair of vertical inner walls (4) each supported at at least one point across their width by a web structure (6) of the frame, and strengthening walls (14) extending over substantially the whole height of the slide bearing between the outer edges (15) of the vertical inner walls (4) and the web structure (6). By this means a rigid structure may be provided which does not suffer from stress peaks as occur in previous such structures using horizontal cross-ribs. <IMAGE>

    (54) STANDING PISTON MACHINE
    one
    The invention relates to units and parts of machines, namely, frames, pistons, matsshn, mainly piston machines with a crosshead.
    The known stand for reciprocating machines, containing side and end walls, one side of which is connected in its middle part with the side walls, and the part, with a rim, is designed as a crosshead guide 1,
    The disadvantage of this rack is low rigidity and reliability of construction.
    The aim of the invention is to increase the reliability of the structure by increasing its rigidity.
    This is achieved by the fact that the proposed rack of a piston machine, comprising side and end walls, one side of which is connected in its middle part with side walls and part of the other is made in the form of a crosshead, provided with vertical stiffeners connected to the ends of the end walls and installed at an acute angle to the side walls, and between the side walls of the rack, in the area of attachment of stiffeners, set
    The reinforcing ribs are fins, the height of the reinforcing ribs and the ribs being equal to the height of the crosshead guides. The surface of the part of the end walls, made in the form of crosshead guides, may have a coating, for example a self-lubricating material.
    FIG. 1 shows the rack Porsche 0 nevy machine, general view; in fig. 2 a section A – D in FIG. one.
    The stand contains side walls 1, to which the end walls 2 are fastened by a middle part of the pri1B, the opposite side of the latter being made in the form of guides 3 of the cross-head 4, Vertical stiffening ribs 5 are connected to the ends of the torus 20 walls 2 and are installed at an acute angle to the side walls 1 ... Between the side walls 1, in the zone of attachment of the ribs 5, reinforcing distance ribs 6 are installed.
    25 The height of the ribs 6 and the ribs 5 is equal to the height of the crosshead 3 of the cross-head 4. Part of the surface of the end walls 2, made in the form of guides 3 of the cross-head 4, has a coating 7, for example 30, of self-lubricating material, which can be pressed or glued ,.
    During the operation of the piston machine, the forces from the crosshead 4 are transmitted by the guides 3 of the end wall 2. The stiffening ribs 5. are distributed over the entire height of the guides 3, therefore the forces of the side walls 2 are transmitted evenly over the entire height, which prevents the occurrence of stress peaks and ensures better rack stiffness.
