| Abstract: | The reason of valve locating snap ring dropping was studied based on theory analysis.Some methods were supplied to deal with valve locating snap ring dropping.Locating snap ring dropping and prevention method were simulated with FEA method.The results proved the theory analysis.By the theory analysis and FEA simulation,the mechanism of preventing locating snap ring from dropping was understood better,and the results provide direction for design of locating snap ring and its groove. |
