spur bevel gears are usually formed by generating method on gear planer. On the basis of establishing the meshing coordinate system of spur bevel gear with installation error, a method is proposed to express the installation error sensitivity of the modified tooth surface of spur bevel gear by using...
Straight bevel gears are formed by “one fire and two forging”. The tooth surface of the tooth die is subjected to the thermal impact of the high-temperature gear blank, and the temperature rises rapidly, up to 600 ° C. after the forging is out of the die, the water...
(1) During the precision forging of spur bevel gears, there are many factors that affect the metal flow behavior. In addition to the shape and size of the preform and the preform, there are also the upper die speed, the friction coefficient between the blank and the die, the...
Several common formulas for calculating the precision forging forming force of spur bevel gears are given below. Formula 1: Where F – total deformation area (including spur bevel gear forgings, skin and flash), unit: mm2; K – steel grade coefficient (k=0.9 for carbon structural steel with carbon content lower...
