Power density and efficiency have always been the main goals pursued in the field of mechanical transmission, among which gear transmission with few teeth is one of the important means to achieve this goal. High reduction hypoid gear (HRH) has the advantages of high degree of engagement, small number...
1. Part installation and positioning Install the NC turntable in the middle of the workbench of the vertical machining center, install the fixture on the turntable, install the parts on the fixture, align the positioning pin on the fixture with a tooth slot of the parts, then clamp the...
1. Software preparation The secondary development is carried out on the basis of NX software, and a small plug-in is designed. Different models can be obtained by inputting the adjustment parameters of the machine tool for the actual machining of spiral bevel gears. The three-dimensional data of a tooth...
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...
