Plastic deformation and failure of automobile gear tooth surface
When the contact stress of automobile gear is too large, the plastic flow of tooth surface metal due to yield is called tooth surface plastic deformation. It generally occurs on the soft tooth surface. When the hardness of the tooth surface is low, due to short-term overload or large...

Tooth alignment error and tooth profile error of smooth large gear after test
In order to facilitate the comparison with the parameters before the test, the smooth big gear after the test also adopts full tooth measurement. A-F in the figure is the tooth direction error diagram of the smooth big gear. Compared with that before the test, the tooth direction error...

Gluing failure of automobile gear tooth surface
In the high-speed and heavy-duty gear transmission of automobile gears, the pressure in the meshing area of the tooth surface is high, and the sliding speed is high, which makes the working surface temperature very high, and the viscosity of the lubricating oil is reduced, resulting in lubrication failure,...

Pitting failure of automobile gear tooth surface
Fatigue pitting of the tooth surface of automobile gear is a common failure form of closed soft tooth surface gear transmission with good lubrication. When the gear teeth work, the transmitted working load is added to the limited actual contact area, and a great pressure will be generated on...

Wear failure of automobile gear tooth surface
In automobile gear transmission, there are many different forms of tooth surface wear with different working conditions. There are mainly two kinds: abrasive wear caused by hard debris entering the friction surface; In addition to rolling, there is relative sliding between meshing tooth surfaces, which is abrasive wear caused...

Tooth alignment error and tooth profile error of pit bionic large gear before test
In order to make it more convenient and intuitive to compare the measurement data of smooth big gear and pit big gear, the pit big gear also adopts full tooth measurement. The changes of morphological parameters of each tooth before and after the test are analyzed in detail. Every...

Tooth direction error and tooth profile error of smooth large gear before test
The smooth big gear has 24 teeth in total, which are measured by full teeth. The changes of morphological parameters of each tooth before and after the test are analyzed in detail. Every four teeth are grouped into a group, and the tooth direction error and tooth profile error...

Matlab simulation of gear tooth surface
The relevant parameters used are shown in the table. In order to solve the tooth surface of instant noodle gear, as shown in Fig. 1, the tooth surface of face gear is expressed in the coordinate system SW. S2 rotates counterclockwise around axis x2 γ M obtains SW, and...

Split flow finishing of spiral bevel gear tooth top
It can be seen from the research that the change of finishing forming force is not only affected by the size of finishing quantity, but also related to the obstruction of die cavity. Therefore, according to the tooth shape structure of the spiral bevel gear, the tooth root circle...
