因凿岩机往复共轭与回转共轭的工作条件特殊,必需进行专门的实验室试验,以查明这些零件的加荷规范和工作条件。在机器上对可动花键共轭和螺旋共轭所作的试验结果列举如下。摩擦表面之间润滑油的消耗量是14厘米~3/小时,就保证了共轭零件在临界摩擦下的工作。试验前,零件跑合运转3小时。然后,在一定位置上,测量花键厚度和花键共轭或螺 Due to the special working conditions of reciprocating conjugate and rotary conjugates of rock drills, special laboratory tests are required to ascertain the loading specifications and working conditions of these parts. Test results for movable spline conjugates and spiral conjugates on the machine are listed below. The consumption of lubricating oil between the friction surfaces is 14 centimeters to 3/hour, which ensures the work of the conjugate parts under critical friction. Before the test, the parts run for 3 hours. Then, in a certain position, measure the spline thickness and spline conjugate or screw
