    摘要: The invention relates to a drive (1) comprising a piston machine in particular in the form of a combustion engine, said drive having a device for efficiently reducing alternating torques produced by rotational nonuniformities on the basis of the engine speed- and torque pulsation of the combustion engine and the mass forces created by the reciprocating motion of the piston and the connecting rod during operation. For this purpose, a crankshaft (2) of the combustion engine carries a sun wheel (3) of a planetary gearbox (4). In a per se known manner, the planetary gearbox (4) also comprises three planet gears (5, 6, 7) and a ring gear (8). In the embodiment shown, the planet gear (5) is used to drive a balancing shaft (9) which can be driven thereby in the opposite direction. In order to be able to drive, in addition to this balancing shaft (9), also another balancing shaft (10) in the same direction of rotation as the crankshaft (2), the ring gear (8) has, in addition to inner teeth (11) which engage with the planet gears (5, 6, 7), outer teeth (12) for a toothed wheel (13) which drives the second balancing shaft (10), wherein the number of teeth of the inner toothing (11) and of the outer toothing (12) match.

    摘要: A balance system for a single cylinder engine (10) is described. The single cylinder engine (10) generates forces, that if left unbalanced, cause significant vibrations or movement to the single cylinder engine (10) and devices driven by the single cylinder engine (10). The balance shaft includes a primary balance shaft (21) for a first type of forces and at least one secondary balance shaft (23) for a second type of forces. The secondary balance shaft (23) is driven directly by the primary balance shaft (21). In one example, only one secondary balance shaft (23) may be used, which may leave some forces unbalanced but is more space and cost effective. In another example, two or more secondary balance shafts may be included in a drive chain such that one secondary balance shaft drive the next secondary balance shaft.

    摘要: A rolling bearing of a balancer shaft device is positioned on an imaginary circle concentric with an axis of a shaft portion of a balancer shaft as viewed in a radial cross-section, and includes a cylindrical portion which covers the shaft portion. An outer circumferential surface of the cylindrical portion defines an inner ring raceway surface of an inner ring member on which a rolling element of the rolling bearing rolls. A part of the shaft portion of the balancer shaft, at a position on which the rolling bearing is disposed, has a cutout formed at a portion which does not contribute to offsetting of rotational vibration of a crankshaft.
