Abstract: A balancing shaft unit for balancing inertia or torque in an internal combustion engine of a motor vehicle. The balancing shaft unit includes a housing part and at least one balancing shaft having at least one counterweight. The housing part is made in one piece and has at least two integrated bearing sections with a respective bearing opening. A respective cut-out is formed at longitudinal ends of the balancing shaft in which a respective bearing pin is arranged that is rigidly connected to the balancing shaft and which has a cylindrical bearing section that is supported in a respective one of the bearing openings.

Abstract: The invention relates to a balancing shaft unit for piston machines, in particular internal combustion engines, for installation in a housing with non-divided bearing seats. Said shaft unit consists of at least one balancing shaft, which is configured as one piece with its balancing weight or weights. To allow the shaft unit to be installed in a non-divided housing without any restrictions being placed on its bearing, at least one bearing of the balancing shaft is formed by a narrowing of the balancing shaft that acts as a bearing journal and by a sub-divided bearing ring that is fixed to the housing, whose external diameter is greater than the external diameter of the balancing weight or weights.

Abstract: A piston engine with a compensation shaft unit, wherein a window surrounded by a flange is provided on the crankcase thereof. The flange forms a separating surface to which the housing of the compensation shaft unit is fixed by means of screws. In order to ensure clean, toothed-wheel engagement for the compensation shafts, which are integrated into the housing, and easy assembly, the compensation shaft is provided with a toothed wheel, which protrudes through the window inside the crankcase, and which is driven by a toothed wheel, which is arranged on the crankshaft, and the housing of the compensation shaft unit has a separating surface, which can be displaced in order to adjust the amount of engagement clearance on the separating surface of the crankcase before the screws are tightened.
