一、概述在内燃机车液力传动装置中,轴与轮毂(如齿轮,法兰等)的联接普遍采用锥度静压配合。这种联接的特点是,轴的外径大于轮毂孔的内径(即具有过盈量)、并在其配合表面具有相同的锥度1∶50,把油压入轴和轮毂的配合面之间,使轮毂孔稍许扩大,同时从轴向推压,轮毂即可逐渐向锥面大端移动。此时,油也作为润滑剂使配合面不发生接触、从而避免
First, an overview In the diesel locomotive hydraulic transmission device, the shaft and the hub (such as gears, flanges, etc.) commonly used taper joint static pressure. This coupling is characterized by the shaft having an outer diameter greater than the inner diameter of the hub bore (i.e., having an interference) and having the same taper of 1:50 at its mating surface, pushing oil into the mating face of the hub and hub, So that a slight expansion of the hub hole, while pushing from the axial, the hub can be gradually moved to the big end of the cone. In this case, the oil also acts as a lubricant to prevent the mating surfaces from contacting each other
