Method for assembling rotor of oil pump on crankshaft in engine of car, involves sliding rotary part with respect to longitudinal direction of conical element such that one or multiple portions of rotary part slide along conical element

摘要

The method involves placing a rotary shaft (200) in a central opening (311) of a rotary part (310) such that a rotation axis of the rotary part coincides with a rotation axis of the rotary shaft. A conical element i.e. assembly tool (100), is placed around the shaft and in the central opening. The rotary part is slid with respect to a longitudinal direction of the conical element such that one or multiple portions of the rotary part slide along the conical element and one or multiple portions of the rotary part come in contact with the shaft after sliding on the conical element.
