摘　　要：根据液压凿岩机活塞的运动规律,建立了活塞运动微分方程,推导了其运动学参数的解析表达式。研究了液压凿岩机活塞与缸体间隙密封段的局部温升和能量损失,建立了其数学模型。根据该模型可以求得活塞与缸体之间合理的间隙范围。According to movement of piston in hydraulic rock drill, the deferential equation on piston was set up and its kinematic parameters' formula was deduced. Local temperature rising and energy loss in sealing gap between piston and hole was analyzed and its mathematic model was set up.Reasonable gap between piston and hole were extracted by means of this model.
