摘要： Methods and systems are provided for an oil pump mounting structure that provides accessibility and removal of the oil pump without removing a balancer shaft. While periodically servicing or replacing the oil pump may be necessary throughout the lifetime of an engine, it is desirable to allow for easy removal of the oil pump without removing and reassembling other engine components. To provide alignment and a rigid connection between the oil pump and engine frame while allowing for removal of the oil pump without removing other components, dowel bolts with unthreaded, threaded, and dowel portions are used to mount the oil pump to the engine frame.

摘要： The present invention relates to balancing of a rotating anode. In order to provide a facilitated balancing of a rotating anode allowing balancing also in a state where the rotating anode disk is mounted inside an X-ray tube, an adjustment device (54) for balancing a rotating anode disk in an operating state is provided. The adjustment device comprises at least a first plurality (72) of balancing elements (74), wherein the balancing elements are attached to at least one circular ring structure (76), and wherein the balancing elements each comprise a balancing portion (80) mounted to the circular ring structure via a bending portion (82). The bending portions are configured to be heated to a bending temperature to allow a radial pivoting movement (84) of the balancing portion from a first state (86) into a second state (88) caused by centrifugal forces upon rotation, wherein in the first state, a centre of mass of the balancing portion is closer to a centre (90) of the circular ring structure than the second state.
