摘要：

In this study, the forging processes of spur gears have been investigated. The forging processes of spur gears have been classified into two types of operations, guiding one and clamping one in this investigation. Two types of forging have been analyzed by using upper bound method. The relative average punch pressure have been calculated and compared with each others for various modules and numbers of teeth on the forging of spur gears. The forging experiments were carried out with a commercial aluminum alloy. The predicted forging loads obtained by the present upper bound methods are shown to approximate to the experimental results at final filling-up stage. The forged parts obtained through the guiding type forging were compared with those obtained through the clamping type forging. (C) 1998 Elsevier Science Ltd. All rights reserved.
