1. Technical difficulties There are several difficulties in carrying out bevel gear tooth top trimming under traditional conditions: (1) Tooth profile problem. The parts requiring trimming are spiral bevel gears, and the tooth profile is involute. It is difficult for the cutter to process according to the involute shape...
Bevel gear is a component that can drive according to a stable transmission ratio. Because of its high transmission efficiency, high bearing capacity, stable transmission, wear resistance and compact structure, it is widely used in mechanical products such as automobiles and tractors. In order to prevent the involute tooth...
The contact spots of three new bevel gears are shown in Figure 1. It can be seen that for single point contact conjugate curve bevel gears, the contact spots are still located in the middle of the tooth surface after assembly. For the multi-point contact bevel gear, after assembly,...
According to the method, the equiangular spiral bevel gear with five point contact can also be constructed. Because the section curve of the driving surface can be taken arbitrarily, the section curve of the pinion can also be similar to the design method of bevel gear, using double segment...
The finite element method is still used to analyze the force of bevel gear model. The grid size setting, physical parameters, boundary conditions and their application methods are basically consistent with the finite element analysis of the model in Chapter 3. For the bevel gear entity, the low-order hexahedron...
With the intensification of global warming, it is urgent for countries to carry out energy transformation and develop high-quality low-carbon economy. In this context, the country has established the national policy of building an ecological civilization society, made efforts to improve the policy of energy conservation and emission reduction,...
Based on the design process, the equiangular spiral bevel gear with discontinuous pure rolling contact can be designed. To change the equiangular spiral bevel gear into discontinuous pure rolling contact, only Γ 1 add a displacement along its rotation axis, as shown in Figure 1. At this time, under...
Similarly, the finite element method is still used to analyze the force of pure roll contact long epicycloid bevel gear. For the entity of long epicycloid bevel gear, the low-order hexahedron element solid185 is selected to divide the large and small parts of the grid. Near the contact area,...
It can be seen that the tooth surface shape of pure roll contact long epicycloid bevel gear can be controlled by the blade curve. Similar to pure rolling contact equiangular spiral bevel gear and pure rolling contact equidistant spiral bevel gear, the blade curve can be taken as double...
In terms of fully CNC gear milling technology, Oricon and Klingenberg developed S-Series and AMK series mechanical cycloidal bevel gear milling machines based on their respective design and processing theories. Both types of machine tools adopt rocking table structure and complex mechanical transmission chain to realize the generative movement...
