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...
1.Involute helical cylindrical gear defined by modulus 1) Use the common normal micrometer (or digital caliper) to measure the common normal length across K teeth and K + 1 teeth, that is, the measured value of the common normal length wk across K teeth and the common normal length...
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....
Taking the initial forging temperature as 1000 ° C, 1050 ° C and 1100 ° C respectively, and the friction coefficient as 0.3 and 0.7, the forging process of driving spiral bevel gear blank is numerically simulated, and the effects of initial forging temperature and friction coefficient on forming...
The motion model of hypoid gear pair is established. The pinion of hypoid gear pair applies a speed of 60R / min and the driven gear applies a torque of 480nm. The simulation time is 2S and the frame rate is set to 20 frames / sec. The motion...
The research shows that the tooth profile of a single tooth of hypoid gear is a closed profile surrounded by four parts: partial spherical involute, tooth top arc segment, tooth root arc segment and tooth root transition curve. After the establishment of hypoid gear blank, using the function of...
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...
