| The paper presents a new method for forming a hollow shaft with a triangular rosetteshaped flange on its end. The part being investigated is used as a propeller shaft in helicopters. The product must be monolithic, therefore it cannot be produced by methods which consist in joining a flange with a tube. Up till now, such shafts have been produced by machining from solid barstock, the process which generates material losses exceeding 90%. The application of the proposed flanging method results in a significant reduction in both material and labour consumption, which leads to lower production costs. Due to beneflcial texture of the shaft flange, shafts produced by this method exhibit better strength properties than shafts produced by machining. The paper presents the results of a numerical analysis of the flanging process, performer using DEF0RM-3D software. Also, experimental tests were conducted using a threeslide forging press. Theoretical and experimental results obtained confirm the effectiveness of the new method for forming this part. |
