Can the gear reducer continue to rotate if a tooth is broken?

A gear reducer is a common industrial transmission device, which is usually used to slow down the speed of a power source such as a high-speed rotating motor, and output a certain torque on the output shaft. The core component of the gear reducer to achieve deceleration is the gear. Therefore, if the gear is broken during the use of the gear reducer, it will have a great impact on the equipment.

Early Broken Teeth Analysis and Solution of Slewing Bearing

There are two main reasons for the early failure of slewing bearings used in excavators: one is broken teeth; the other is raceway damage. Among them, broken teeth are the main reason, accounting for more than 90%, and most of them occur within six months after the excavator leaves the factory. This not only seriously troubles the product quality reputation of the slewing bearing manufacturer, but also has an adverse impact on the product market of the main engine factory. Therefore, it is the common goal and responsibility of the slewing bearing manufacturer and the main engine factory to seriously solve this problem, and it is also the further cooperation between the two parties. The fundamental guarantee for common development. What is the root cause of the early failure of the slewing bearing due to broken teeth? Design issues; manufacturing issues, material issues; assembly issues or use issues. It is not difficult to find the essence of the problem through the following phenomena:

Slewing bearing - analysis of common faults of bearing abnormal noise:

When the slewing bearing just leaves the factory, some bearings will make a uniform sound of steel ball rolling when it is idling, which is normal. When the slewing bearing is running after installation, it will be accompanied by another abnormal and louder sound, which is called abnormal sound.

Basic structure and working principle of excavator

The commonly used full-slewing is that the power unit of the hydraulic excavator, the main part of the transmission system, the slewing mechanism, auxiliary equipment and the cab, etc. are all installed on a rotatable platform, usually called the upper turntable. Therefore, the single-bucket hydraulic excavator can be summarized into three parts: the working device, the upper turntable and the traveling mechanism.
