A crankshaft is a part of the main engine components and plays critical role in car performance. The component consists journals, pins, flange that experience induction hardening treatment to increase their hardness. Hardness case depth represents important hardness criteria achieved by process. This paper aims evaluate quality analyzing measurement. control chart shows results, which presents ...

Abstract The Crankshaft Full-automatic Measuring Machine (CFMM) features high accuracy, efficiency and complete measurement parameters, represents the forefront of a geometric crankshaft accuracy measuring instrument. One its core technologies is high-precision radial following connecting rod journal measurement. In this paper, an independent probe design scheme combining flexible dual-complex ...

The opposed-power reciprocating pump has the characteristics of high pressure, large flow, and efficiency energy saving. However, due to special structure pump, existing theoretical methods cannot analyze its dynamic performance. Therefore, this paper proposes a method analyzing power end pump. Firstly, according working principle structural traditional plunger novel complex is analyzed by anal...
