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...

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...
