摘  要:
针对轴向柱塞泵配流副受力不均匀、配流盘承受偏载力矩、低压区摩擦润滑效果差等问题,提出对配流副低压区进行织构化。建立了配流副低压区织构化的分析模型。研究了微凹坑直径、深度、面积率对低压区的油膜承载力、补偿力矩的影响。结果表明:较大直径的微凹坑提供较大的承载力和补偿力矩;面积率的合适范围为12%~18%,微凹坑的深度对承载力和补偿力矩影响较大。

摘  要:
In order to deal with the problems in axial piston pump such as uneven loading of port plate pair,offset load moment of port plate and bad lubrication of port plate pair in low pressure area,textured port plate in low pressure area was studied.An analysis model was established to study the effects of diameter,depth and area ratio of micro-dimple on load carrying capacity and compensating torque.The results showed that the micro-dimples with greater dimple diameter could induce higher load carrying capacity and compensation torque.The optimum dimple area ratio was in the range of 12%~18% and the dimple depth gave an obvious affection on load carrying capacity and compensation torque.
