    A gear wheel driven air compressor that is constructed as a piston compressor, the drive gear wheel of which, on the air compressor crankshaft, meshes with a gear wheel on the camshaft of the internal combustion engine. With drives of this type, the negative torque of the air compressor, which is produced once the upper dead center position of the air compressor piston has been reached, leads to a sudden flank change in the tooth mesh, which is associated with an unpleasant noise. In order to reduce this noise, it is known to make the meshing flank clearance as small as possible. However, clearances which are too small lead to increased rotational bending strain on the air compressor crankshaft and the camshaft. In order to prevent this, a sinusoidal meshing flank clearance change is proposed, which is obtained via a specific eccentricity of the air compressor drive gear wheel, which is associated with the upper dead center position of the air compressor piston.

    专利说明:

    The invention relates to mechanical engineering, in particular to actuators of internal combustion engines for compressors.
    An auxiliary drive of an internal combustion engine for an air compressor is known, comprising a drive gear mounted on the engine output shaft, an intermediate gear wheel mounted on the engine camshaft and kinematically coupled to the drive gear wheel, a driven gear mounted on the crankshaft of a piston compressor, engaged with an intermediate gear wheel.
    A disadvantage of the known device is the occurrence of shock noise arising in gearing.
    The purpose of the invention is to reduce the noise level of the side surfaces of the teeth, in particular in the area of the top dead center.
    FIG. 1 shows an auxiliary drive for an air compressor: FIG. 2 — an assembly of fastening the driven gear with a clamping sleeve; in fig. 3 is a graphical dependence of the magnitude of the normal lateral clearance between the teeth of the intermediate gear mounted on the camshaft and the teeth of the driven gear mounted on. to the crankshaft of the compressor, depending on the angle of rotation of the crankshaft of the compressor.
    The air-assisted drive of the internal combustion engine of the air compressor contains a drive gear installed on the output shaft of the engine (not shown), an air compressor with cylinder 1i in which is placed a piston 2 connected by a connecting rod 3 to the crankshaft 4.
    On the crankshaft 4 of the compressor, a driven gear 5 is installed, the axis 6 of rotation of the driven gear 5 is installed, with a certain displacement (eccentricity) e relative to the axis 7 of rotation of the crankshaft 4. The driven gear 5 engages with the intermediate gear 8 mounted on the camshaft of the internal combustion engine. The gap between the precise gear 8 is kinematically connected with the driving gear mounted on the output shaft of the internal combustion engine.
    The maximum eccentricity e, which is the distance between the axes of rotation 6 and 7, is ensured when the piston 2 is in the top dead center, when the axes 6, 7 and the axis of rotation of the intermediate gear wheel 8 lie on one
    straight 9. At the same time between the axis 10 of cylinder 1 and straight 9 a certain angle is formed
    Driven gear 5 is fixed
    on the crankshaft 4 by means of a clamping sleeve 11, which enters the holes 12 and 13, made respectively in the end contact surfaces of the driven gear 5 and the crankshaft 4.
    The clamping sleeve 11 is inserted into the hole 13 of the crankshaft 4 and then the driven gear 5 is installed on the sleeve 11 by means of the hole 12. A screw is installed in the OTBepCTMie sleeve 11.
    (not shown), which during its tightening presses the sleeve 11 to the seating surfaces.
    The auxiliary drive of the internal combustion engine for an air compressor operates as follows.
    The rotation of the drive gear of the output shaft of the internal combustion engine is transmitted to the intermediate gear wheel 8, which, in turn,
    transmits the torque to the driven gear 5 and the crankshaft 4 of the air compressor.
    The piston 2 receives a reciprocating motion from the crankshaft 4 through the connecting rod 3.
    Installing the driven gear 5 with eccentricity about the axis of rotation of the crankshaft 4 reduces the lateral clearance between the teeth
    gears 5 and 8 at the desired time, i.e. in the area of the piston, in the upper dead point.
    Practically, when the crankshaft 4 rotates 360 °, a sinusoidal
    the change in the size of the side gap (Fig. 3). On the ordinate axis there is a lateral clearance (in mm) and on the abscissa, degrees of rotation of the crankshaft 4. The indicated graphical dependence is valid for
    eccentricity e 0.15 mm.
    The eccentric installation of the gear 5 relative to the axis 7 of the crankshaft 4 reduces noise and improves bearing performance.
