The invention discloses an abrasion-resistant diesel engine crankshaft. The abrasion-resistant diesel engine crankshaft comprises a crankshaft front arm and a crankshaft rear arm. A crankshaft journalis fixedly mounted on the outer surface of one side of the crankshaft front arm. A bonding pad is fixedly mounted on the outer surface of one end of the crankshaft journal. A high-manganese alloy pipe is arranged on the outer surface of the crankshaft journal in a sleeving mode. An alloy steel core is arranged in the middle of the interior of the crankshaft journal. A journal oil hole is fixedlyformed in the outer surface of one side of the crankshaft journal. A rear end shaft is fixedly mounted on the outer surface of one side of the crankshaft rear arm. A rear end shaft sleeve is fixedly mounted on the outer surface of one side of the rear end shaft. According to the abrasion-resistant diesel engine crankshaft, the high-manganese alloy pipe, the alloy steel core and the distribution oil hole are arranged, the abrasion degree of the crankshaft journal can be lowered, the strength of the crankshaft journal can be improved, the crankshaft journal can bear higher torque, the lubricating effect of the oil hole can be better, and the abrasion-resistant diesel engine crankshaft can adapt to different operations and has better application prospects.
