Split type connecting rod |
摘要 |
A split type connecting rod is capable of prevent ing problems of peeling and falling at the time of fracturing and splitting, securing alignment accuracy after the fracturing, reducing a processing time necessary for processing the groove and improving the processing accuracy. This split type connecting rod 100 includes a valley 106 formed on the inner circumferential surface of a crank-pin hole 101d of a large end portion 101e. Fracture starting point grooves 105 are also formed at the base of the valley 106. |
