1. Definition and Calculation of Coincidence The ratio between the length of the actual meshing line and the pitch of the base circle is called coincidence. As a condition for measuring the continuous transmission of involute gears, the coincidence degree should be satisfied ε ≥ 1, the greater the...

Meshing Process of Involute Gears
The generating line is a straight line. When the generating line rolls along the base circle, the locus formed by any point A on the generating line is an involute. In the figure, the arc AK is the locus formed by point A, and the arc AK is the...

Involute gear meshing process
In mechanical transmission, gear transmission, belt pulley transmission and sprocket transmission are the three most common transmission mechanisms. Compared with belt pulley drive and sprocket drive, involute gear drive has the characteristics of high transmission efficiency, stability, small size of mechanism, etc., so gear drive is most widely used....

Research status of involute gear geometry theory
Chinese scholars have also made many useful contributions to point meshing involute gear pairs. Tao Shengyuan and others discussed in detail the meshing principle and design calculation of Novikov involute gear. Based on the spatial meshing theory, he Jingliang and others analyzed and studied the meshing relationship between conjugate...

Study on geometric theory of involute gear
The geometric configuration of involute gear teeth has a great influence on the performance of involute gear transmission system. The use and transmission performance of involute gears are different with different tooth shapes. For the tooth profile configuration of involute gear, the conjugate surface theory is more mature at...

Parametric design of involute gear transmission system
According to the performance requirements of the reducer, the technical parameters are determined on the basis of the above structural scheme, and eight links are discussed, including transmission ratio distribution, motion and motion parameter design, mechanical model establishment, strength design of involute gear pair, shafting structure and strength check,...

Isothermal forging technology of involute gear
Isothermal forging technology originated in the United States in the 1960s. It refers to the forging and forming of blank under relatively stable temperature. Isothermal forging is suitable for the precision forming of difficult to deform materials. Perer et al analyzed the die design and mechanical properties of AA5083...

Development of precision forging technology for Involute Gears
The precision forging of involute gear originated in Germany. In the 1950s, because there were not enough involute gear processing machines, the Germans used EDM to process the forging die cavity and tried to process bevel gear by ingenious hot die forging. German BLW company first obtained the patent...

Involute gear tooth profile machining method
The key of involute gear machining is tooth profile machining. According to whether the material needs to be removed, the methods of involute gear machining can be divided into cutting machining and plastic forming. At present, the method of Machining Involute Gears in industrial production is still mainly cutting....

Realization of involute gear parametric modeling
1. Create global variable equation Click the command “Σ equation” in the “tools” menu of SolidWorks software, and use the global variable function to input the module m, number of teeth Z, indexing circle diameter D, base circle diameter dB, addendum circle diameter Da, root circle diameter DF and...
