Abstract

본 발명은 메인베어링캡의 분할법에 관한 것으로, 제1단계로; 실린더블럭(1)과 메인베어링캡(2)을 일체성형하고, 제2단계로; 메인베어링과의 마찰을 줄이기 위하여 내경(3)을 가공하며, 제3단계로; 보울트(8) 체결할 수 있도록 체결구멍(4)을 형성하고, 제4단계로; 경계면 둘레를 따라 절단홈(5)을 형성하며, 제5단계로; 상·하 양측으로 인장력을 가하여 실리더블럭(1)과 메인베어링캡(2)을 분리한 후, 제6단계로;보울트(8)를 매개로 실린더블럭(1)에 메인베어링캡(2)을 재조립하도록 된 방법으로 되어, 엔진동작으로 인한 메인베어링캡의 진동이 억제됨으로써 엔진의 소음이 감소됨과 더불어, 부품의 파손이 억제되어지도록 된 것이다The present invention relates to a split method of the main bearing cap, the first step; The cylinder block 1 and the main bearing cap 2 are integrally formed, and in a second step; Processing the inner diameter 3 to reduce friction with the main bearing, in a third step; Forming a fastening hole 4 so as to fasten the bolt 8 and, in a fourth step; Forming a cutting groove 5 along the periphery of the boundary surface; Separating the cylinder block (1) and the main bearing cap (2) by applying a tensile force to the upper and lower sides, and in the sixth step; the main bearing cap (2) to the cylinder block (1) via the bolt (8) Is to be reassembled, the vibration of the main bearing cap due to the operation of the engine is suppressed to reduce the noise of the engine, and to prevent the breakage of parts.
