The manufacturing accuracy of spiral bevel gear directly affects the transmission efficiency, noise, motion accuracy and service life of machinery and equipment. Therefore, the processing and manufacturing of spiral bevel gear has also been widely concerned and studied by experts at home and abroad. The traditional spiral bevel gear...
In a pair of assembled helical gear pairs, backlash J refers to the clearance between the tooth surfaces of meshing helical gears. The side clearance can be measured on the normal plane or along the meshing line, as shown in the figure, but it should be noted that it...
The static and dynamic finite element simulations of the same helical gear pair are carried out respectively. From the stress nephogram of both, whether static or dynamic simulation, the contact line is an inclined line with a certain angle with the edge of the tooth. At the same time,...
In the transmission process of helical gears, their tooth surfaces are in contact with each other, and the tooth surface contact pressure generated by the teeth at different meshing positions is different, which is an inevitable characteristic of involute helical gears in the transmission process. With the rotation and...
According to the analysis of dynamic and static contact stress of different helical gears, the following conclusions can be obtained: ① In the static contact stress analysis of helical gears, under the condition of the same number of teeth, the calculation error of the local tooth model of the...
Pro / mechanism is a special mechanism motion simulation module of Pro / E software. Using Pro / mechanism, the motion simulation analysis of assembly mechanism can be carried out, so that designers can observe the motion state of mechanism more intuitively and vividly. To simulate the hypoid gear...
At present, the main problems faced by the development and wide application of cold extrusion technology of spur gears are as follows: 1) It is difficult to fill the tooth shape and the die is seriously worn Because the metal flow in the cold extrusion process of spur gear...
Comprehensively analyze the research data related to gear machining deformation. In order to realize the prediction of machining deformation of super large spur bevel gear, it is necessary to study a series of theoretical and technical problems, such as the prediction of cutting accuracy of a single split body,...
In the overhaul project of large-scale mechanical press produced, due to the long service time of the press, when checking the transmission mechanism, it is found that the left and right intermediate gears and helical cylindrical gears are seriously worn and can no longer be used, so they must...
To obtain accurate gear contact stress, the premise is to create an accurate three-dimensional solid model, and the creation of accurate tooth profile surface is the key. With the emergence of various large-scale CAD software and the rapid development and application of CAD technology, the establishment of gear model...
