Abstract

The invention relates to the technical field of internal combustion engine mechanism drive systems, in particular to a diesel engine transmission gear. The diesel engine transmission gear comprises an intermediate gear and a middle support. The intermediate gear is fastened to the middle support through a nut and a second gasket. A first spacer and a second spacer are oppositely arranged at the joint of the middle support and the side face of the intermediate gear. The middle support is sleeved with the first spacer, and the second spacer is frozen in an inner hole of the intermediate gear. The two ends of the second spacer are sleeved with check rings, and the outer side of the second spacer is sleeved with a rolling bearing. The first spacer is annular, an oil groove is formed in the inner diameter portion of the first spacer, and two small oil outlets are formed in the oil groove. The second spacer is annular, the inner diameter of the second spacer is adaptive to that of the first spacer, and the outer diameter of the second spacer is in interference fit with the inner hole of the intermediate gear. By adding axial locating measures for the gear and the rolling bearing, the stress state and lubrication state of the gear are improved, and faults of the intermediate gear are reduced.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine mechanical transmission systems, in particular to a diesel engine transmission gear. Background technique [0002] The 240 type diesel engine is mainly installed on Dongfeng 4 series diesel locomotives. Due to the failure of the transmission gear, the transmission performance of the diesel engine was affected, and the diesel engine could not work normally. In 2012, many locomotives were returned to the factory for repair, which had a great impact on the normal production of CSR Qishuyan Locomotive Co., Ltd. The gear transmission system does not work properly, which may cause greater failure of the diesel engine. Therefore, it is very urgent to systematically analyze the cause of transmission gear failure and take necessary measures to completely solve the quality problem. Contents of the invention [0003] In order to overcome the deficiencies of the existing technology, acc...
