Abstract
Изобретение относитс к машиностроению и может быть использовано дл электроэрозионной притирки клапанов. Цель изобретени - повышение качества притирки. Клапану 5 задают вращение относительно седла головки 9 и периодическое возвратно-поступательное его перемещение с приложением нагрузки. На клапан от источника посто нного электрического тока подают отрицательный, а на головку - положительный потенциалы. В процессе притирки воздействуют на сопр гаемые поверхности клапана 5 и головки 9 возбуждаемым между ними электрическим разр дом. Плотность тока притирки определ етс из соотношени I*9893,4 - 56,3P - 1,3 V, где I - плотность тока притирки, кА/м2 The invention relates to mechanical engineering and can be used for electroerosive lapping of valves. The purpose of the invention is to improve the quality of lapping. The valve 5 set the rotation relative to the seat head 9 and its periodic reciprocating movement with the application of the load. Negative voltage is applied to the valve from the constant current source, and positive potentials to the valve head. In the process of lapping, the mating surfaces of the valve 5 and the head 9 are excited by an electric discharge between them. The lapping current density is determined from the ratio I * 9893.4 - 56.3P - 1.3 V, where I is the lapping current density, kA / m 2
P - удельное давление клапана на головку, МПаP - valve specific pressure per head, MPa
V - скорость вращени посадочного по ска клапана, м/мин. 1 ил., 1 табл.V is the speed of rotation of the valve landing speed, m / min. 1 ill., 1 tab.
