Abstract (en)

[origin: US4510898A] A reciprocating piston internal combustion engine equipped with a vibration-damping balancing shaft that is rotatably supported in a bearing housing which in turn is secured at the cylinder crankcase by means of a threaded connection; in order to support the rotational forces of the balancing shaft between bearing housing and cylinder housing without play, at least one of the bolts of the threaded connection includes a conically shaped neck that cooperates with a corresponding chamfering in the bearing housing.
