高转速轴向柱塞泵滑靴盘替代选材的研究
Study on Alternative Material Selection of Swash Plate for High Speed Axial Piston Pump
摘要
Abstract
The local temperature of the swash plate increases close to the tempering temperature of the material under the swash plate axial pistion pump slipper pair working condition of high speed and large load.As a result,the residual austenite phase transformation causes the material surface expansion,the formation of static pressure support oil film,the surface hardness and durability decrease and other problems.Based on the premise of improving the friction and wear performance of the axial piston pump friction pair under high speed operation.A comparative analysis between the substitute material and the finished sample through composition analysis,high temperature treatment,friction and wear experiments is conducted.The results show that the average surface hardness of B material is increased by 17.7%compared with the original finished material at room temperature.After being stored at 400℃for 10 h,the surface hardness of B material can still remain above 700 HV,the average maximum surface deformation of no more than 1 μm on the surface,and the average wear is reduced by 5.9%compared to the finished sample.The possibility of substitute material selection for swash plate axial piston pump under high speed operation is verified,which provides a reference for the follow-up research on material selection of swash plate axial piston pump.关键词
