东风型内燃机车的主机油泵安装在柴油机的泵支承板上,它由柴油机下曲轴通过小弹性齿轮和用螺栓紧固在柴油机机体垂直端板上的主机油泵传动装置驱动。该传动装置的结构如图1所示。主机油泵传动装置中主机油泵传动轴的损坏,是东风型内燃机车多年来的惯性故障处所之一。该传动轴的故障多数发生在轴的 The main engine oil pump of the Dongfeng diesel locomotive is installed on the pump support plate of the diesel engine and is driven by the lower crankshaft of the diesel engine through a small elastic gear and a main oil pump transmission device bolted on the vertical end plate of the diesel engine body. The structure of the transmission shown in Figure 1. Main engine oil pump drive shaft damage in the main oil pump is Dongfeng diesel locomotive over the years one of the inertia failure. Most of the shaft failure occurred in the shaft
