The equivalent stress in the forging process of equal height spiral bevel gear is an important analysis index, which affects the deformation of the whole die and tooth profile and the accuracy of equal height spiral bevel gear forging. Firstly, taking the blank as an example, the equivalent stress...
Taking 18CrNiMo7-6 spur gear as the research object, the finite element models of three schemes are established, and the warm forging process of spur gear is simulated respectively. The distribution of forming load, equal effect force field distribution and tooth cavity filling in the forming process are analyzed, the...
Cold finishing process is the last process in compound forming. It is the key point in the whole process to make the tooth surface size of spur gear forging meet the requirements of part drawing and improve the surface quality of spur gear forging. Cold finishing adopts extrusion forming....
Professor Liu Quankun of Hefei University of technology proposed to simulate the continuous extrusion forming of spur gear through the streamlined concave model cavity based on modeling, which can well improve the filling of the corner of spur gear and improve the uniformity of deformation. Meng Guanjun, Qu Xinhuai,...
At present, there is little research on die modeling and precision forging process of equal high tooth spiral bevel gear. Most researchers mainly study spur bevel gear and spiral bevel gear. Zhang Lin developed the precision forging process of spur bevel gear based on the central split flow method,...
In 1987, British universities first proposed the idea of precision forging hollow parts with floating die. According to the principle of floating die, the molds for manufacturing spur gear and helical gear are designed by Iranian university and British university, and the forming of spur gear and helical gear...
Ohga K and Konda K first proposed to apply the shunting process to the precision forging technology of spur gears in, so as to reduce the forming load through material shunting and facilitate the filling of tooth profile. The split flow method is developed, and the inward split flow...
The stroke load curve of the die in the general forging process of spiral bevel gear is shown in the figure. The forming process of spiral bevel gear assembly includes upsetting and die forging. Figure a shows that the load at the beginning of the upsetting process is 0t....
Gear is an important part of mechanical transmission. Its main function is to transmit power and change the speed and direction of movement. Because of its large power range, high transmission efficiency, accurate transmission ratio, long service life, safety and reliability, it is widely used in various projects. Traditional...
Although a lot of research has been done on the precision forging of spiral bevel gear at home and abroad, there are still some problems in the process of applying it to production practice: (1) High requirements for molds. The tooth profile of spiral bevel gear is more complex,...
