    Disclosed is a motorized chain saw, comprising: a handle-housing member including at least one handle for carrying the saw; at least one crankcase member; and at least one means including a vibration-damping elastic member for providing a shock absorbing connection between the housing member and the crankcase member. The elastic member is laterally expandable and includes at least one axial expansion opening for accepting a selectively insertable means for expanding the rubber elastic member.

    (5) CHAIN MOTOR SAW
    The invention relates to devices for sawing wood and can be used in the logging industry.
    Chain motor saws are known that contain an active block having a crank mechanism, a casing with control handles and cylindrical rubber shock absorbers connecting the active block with the casing.
    A disadvantage of the known chain saws is the difficulty of mounting shock absorbers in an active unit.
    The purpose of the invention is to simplify the installation of shock absorbers.
    The goal is achieved by the fact that the active unit has holes, and the shock absorbers are located in these holes, made in the form of bushings, provided with spacer elements for securing the bushings in the active block and fixed to the casing by means of screws.
    In addition, the sleeve and the screws are aligned.
    i The ends of the sleeves are made with shoulders.
    In this case, lids are located in the openings of the active unit. 5 In addition, the spacers can be made in the form of dowels and spacer screws on the side surface of the casing or in the form of spring rings.
    10 FIG. 1 shows a chain saw, a longitudinal section; FIG. 2 - the location of the shock absorbers in the saw; in fig. 3 spacer, made in the form of dowels)
    15 in FIG. j - the same, in the form of a tapered bushing; in fig. 5 the same, in the form of a spring ring.
    The chain saw contains an active block-motor 1 with a housing

    Claims (3)
    [1]
    20 2 crank mechanism crankshaft 3, connecting rod 4, piston 5. Casing 6 is located in the middle part of the active unit and has a rear 7 and front (not shown) control handles. Shock absorbers 8 are located between the active unit and the casing 6, which are tightly attached to the casing 6 by the ends, and fixed in it by means of screws 9. To increase the reliability of the connection, the shock absorbers 8, which are made in the form of rubber bushings, have metal shoulders 10. Whether on the engine 1 and the casing 6 in the case of the destruction of the rubber bushings, the height of the head of each screw 9. Including the height of the shoulders 10, is greater than the gap between the engine 1 and the casing 6. The shock absorbers on the engine are creased by means of a spacer elements that can be made in the form of dowels 11, having on the side surface on the side opposite the engine 1, grooves 12, B. Opening 13 of each dowel 11 is screwed in the spacer screw 1, which at the same time spreads a part of the d 11 and slots 12 and the dowel 11 in turn spreads the rubber sleeve, pressing the latter against the walls of the hole 15 in the engine 1. Moreover, the spacer elements can be made in the form of spring rings 16 inserted into the rubber sleeves, which they press hole surfaces 15. Possible but execution of the expansible element and a cone-shaped sleeve 17 fixed by a ring 18. The apertures 15 in the engine 1 are closed lid 19 mi thereby eliminating contamination of these holes. The disassembly of the shock absorbers 8 is carried out as follows. The covers 19 are removed, the spacers are removed from the sleeves, the screws 9 are unscrewed and the rubber sleeves are removed from the openings 15. This shock absorbers design and their fastening means eliminate S4 direct contact of the active engine block, i.e. oscillation source, with a case on which the control handles are fixed. Claim 1. Chained saw, containing an active block with a crank mechanism, a casing with control handles and connecting. An active block with a casing, cylindrical rubber shock absorbers, distinguished by the fact that, in order to simplify the installation of shock absorbers, the active block has holes, The shock absorbers are located in these openings, are made in the form of bushings, are equipped with retaining elements for fixing the bushings in the active unit and are fixed to the casing by means of screws.

    2. The saw POP.1 is different because the sleeves and screws are aligned.
    [3]
    3. The saw according to claim 1, characterized in that the ends of the bushings are made with shoulders. k. Saw on PP. 1-3, which is equipped with covers located in the openings of the active unit. 5. A saw according to claim 1, characterized by the fact that the spacer elements are made in the form of dowels and spacer screws having slots on the side surface from the casing side. 6. Pyla POP.1, characterized in that the spacer elements are made in the form of spring-loaded xxx rings. Sources of information, rintye taken into account in the examination 1.
