Tooth profile design for precision forging of bevel gears

The precision forged bevel gear tooth surface can be directly applied without machining. It requires that the precision forged gear tooth surface has high dimensional accuracy, so the tooth shape design plays a very important role in the precision forging of bevel gear. There are two main difficulties in...

Involute profile curve equation of bevel gear precision forging

1.Establish involute tooth profile curve equation The theoretical tooth profile curve of spur bevel gear is spherical involute. Because the spherical involute cannot be expanded into a plane, it brings great difficulties to the three-dimensional modeling of bevel gear. Based on the theory of back cone, the equation of...

Design of bevel gear preform

In the hot precision forging of bevel gears, the selection of preform shape and size is very important. It not only affects the tooth forming, but also affects the internal quality of forgings and the service life of forging dies. The following factors need to be considered in the...

Process design for precision forging of bevel gears

When the bevel gear is formed by “one fire two forging” process, the shape and size of preform, pre forging and die cavity size parameters are the main factors affecting whether the metal can fill the die cavity smoothly. Reasonable design of the shape and size of the straight...

Deformation analysis of bevel gear blank

By using the moment area method, the deformation of the bevel gear blank when machining the tooth groove in the middle of the bevel gear blank is obtained. In the finite element analysis of the bevel gear blank, it can be seen that the calculated result is the average...
