| 目的 研究微沟槽织构对采油液力马达定转子配副表面摩擦学性能的影响，为减小液力马达螺旋副的摩擦阻力矩，从而解决大庆油田某型号液力驱动螺杆泵采油系统停机后启动困难的问题提供设计方向。方法 根据螺杆马达螺旋副，建立金属-橡胶平板往复摩擦模型，在金属试件表面加工出不同织构角度和深度的矩形微沟槽，采用正交试验方法，研究不同织构参数对液力马达螺旋副摩擦性能的影响规律，最后再对比分析橡胶试件摩擦磨损试验前后的表面形貌，以掌握织构存在对橡胶定子使用寿命的影响规律。结果 织构角度一定时，除90-5号试件以外，其余各组试件的摩擦因数表现出随织构深度的增加而增加的现象。织构深度一定时，各组试件的摩擦因数随织构角度的增大而表现出先增大后减小的现象。织构角度是摩擦因数的主要影响因素。相同试验条件下，0—5号试件的摩擦因数比未织构试件降低了20.2%。结论 在液力马达定转子这种金属-橡胶接触对中，织构的减摩机理主要是通过微沟槽输送润滑介质，改善润滑条件。织构参数设计合理的试样，在不缩减液力马达使用寿命的条件下可以有效减小摩擦副的摩擦因数，有利于液力驱动螺杆泵采油系统顺利启动。 |

| The work aims to study the influence of micro-groove texture on the surface tribological properties of the stator and rotor pairs of oil extraction hydraulic motors, in order to reduce the frictional resistance torque of the screw pair of the hydraulic motor and solve the problem of difficulty in starting the oil production system of a certain type of hydraulic drive screw pump in Daqing Oilfield after shutdown, it provides a design direction. According to the screw pair model of the screw motor, a metal-rubber flat plate reciprocating friction model was established, and rectangular micro grooves with different texture angles and depths were machined on the surface of the metal specimen. Using the orthogonal test method, carry out the research on the influence of different texture parameters on the friction performance of hydraulic motor spiral pair. Finally, the surface morphology of the rubber specimen before and after the friction and wear test is compared and analyzed to grasp the effect of texture on the service life of the rubber stator. When the texture angle is constant, the friction coefficient of each group of specimens was increased with the increase of texture depth except for the 90-5 test piece; when the texture depth is constant, the friction coefficient of each group of specimens was increased first and then decreased with the increase of texture angle; texture angle is the main influencing factor of friction coefficient. Under the same test conditions, the friction coefficient of the 0—5 specimens was reduced by 20.2% compared with the untextured specimens. In the metal-rubber contact centering of the stator and rotor of the hydraulic motor, the texture reduction mechanism is mainly to transport the lubricating medium through the micro groove to improve the lubrication conditions. The sample with reasonable texture parameter design can effectively reduce the friction coefficient of the friction pair without reducing the service life of the hydraulic motor, which is beneficial to the smooth start of the hydraulic drive screw pump oil extraction system. |
