shrink fit apparatus of fly wheel rotor having the multilayer ring and shrink fit method of fly wheel rotor having the multilayer ring using the same

摘要

An apparatus for forcibly inserting a flywheel rotor having a multilayer ring and a method therefor are provided to considerably reduce the machining error caused by the precise process for the boundary surface formed between rings by using a separate guide member. A certain penetration bore(d3) is formed in a jig member(400). A guide member(300) passes through the jig member. An oil-hydraulic press(500) applies the pressure on an upper part of the guide member. A control means(600) controls the driving of the oil-hydraulic press. An internal ring(200) having the second bore(d2) is arranged on an upper part of the guide member. The first bore(d1) of an outer ring(100) is gradually increased to a certain radius by the pressure. The guide member consists of an upper surface part(310), a lower surface part(320) and an inclined part(330). The oil-hydraulic press for providing the pressure to an upper part of the internal ring is formed on the upper part of the internal ring.
