Counterbalance for an internal combustion engine

摘要

As a counterbalance for an internal combustion engine a counterbalanceweight (7) driven by a crankshaft (2) of the engine by means of a non slipping drive is pivoted on a shaft (6) and combined with the driven part (8) of the non slipping drive. As a stretching or tensioning arrangement for the transmission means (9) of the non slipping drive, the shaft (6) supporting the counterbalanceweight (7) is provided with an eccentrically arranged journal pin (10) pivoted and lockable in the housing (1) of the engine.
