The cold extrusion technology of spur gear is a metal plastic forming process with less and no chip, which has the characteristics of high efficiency, high quality and low consumption. The cold extrusion process of spur gear is to put the metal wool into the extrusion die cavity at...
As shown in the cloud diagram and partial enlarged diagram of the contact stress distribution of the concave spur gear, the maximum contact stress of the concave spur gear in the figure is distributed at the top of the big gear and the root of the pinion, and the...
After the solution is completed, the equivalent stress of the two-dimensional contact of the concave spur gear is displayed by using the ANSYS general post processor, as shown in the cloud diagram and local enlarged diagram of the equivalent stress distribution of the concave spur gear contact. It can...
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,...
Consistent with the boundary condition setting of the smooth spur gear, restrict the degrees of freedom of all nodes in the inner hole of the big gear, restrict the degrees of freedom of all nodes in the UX direction of the inner hole of the small gear, and apply...
Consistent with the two-dimensional modeling of smooth spur gear, the two-dimensional line contact peripheral contour curve of spur gear is drawn by CAXA electronic drawing board and imported into ANSYS. Using the function of generating plane from line in the pre processor, the contour lines of large and small...
Three kinds of warm forging die structures are set according to the structural characteristics of spur gear. As shown in the figure, the floating die structure is adopted for all three schemes. Considering that the diameter of spur gear is large and the height diameter ratio and aperture ratio...
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...
1. Equivalent stress analysis of two-dimensional line contact of smooth spur gears The general post processor in ANSYS is used to display the equivalent stress graph of spur gear contact. The overall distribution cloud diagram of two-dimensional contact equivalent stress of smooth spur gear is shown on the left...
