1045 Heavy Truck Gear

PRODUCT PARAMETERS:

1045 heavy truck gear failure form:

1, 1045 heavy truck gear tooth broken

Tooth fracture is a dangerous failure form, which can be divided into overload fracture, fatigue fracture and random fracture according to different causes.

2, 1045 heavy truck gear tooth surface glued

In high-speed and heavy-duty transmission, the lubricating oil film is destroyed due to the rising temperature of the meshing zone, so that the two tooth surface metals directly contact and bond with each other, with the relative sliding of the tooth surface, the softer tooth surface metal is torn off along the sliding direction to form a groove, this phenomenon is gluing.

3, 1045 heavy card gear tooth surface pitting

When the contact stress of the tooth surface exceeds the contact limit stress of the material, the surface of the tooth surface will produce subtle fatigue cracks, and the expansion of the cracks makes the surface metal particles flake off and form some small pits, commonly known as pitting pits. Pitting will reduce the bearing area of the tooth surface, cause impact and noise, and the tooth will break in serious cases.

4, 1045 heavy truck gear tooth surface wear

There are two kinds of tooth surface wear: (1) abrasive wear caused by hard chips (such as iron chips, sand, etc.) entering the tooth surface; (2) Grinding wear caused by the friction between the tooth surfaces. After excessive wear, a large number of working surface materials are worn off, and the shape of the tooth profile is damaged, often leading to serious noise and vibration, resulting in transmission failure.

5, 1045 heavy card gear plastic deformation

The plastic deformation of tooth surface mainly occurs in the cases of low speed and heavy load, frequent starting and overload. When the working stress of the tooth surface exceeds the yield limit of the material, the plastic flow of the tooth surface is generated, which causes the grooves at the pitch line of the tooth surface of the driving wheel and the convex ridges of the driving wheel.

The several main gear tooth failure forms described above can not only be repaired under normal circumstances, but also delay the occurrence of adverse gear failure by preventing in advance under the condition that the gear material and processing technology can not be changed, and improve the service life of the gear.
