Gear box noise and high temperature analysis <Six>

OF: gear reducer oil manufacturers - Changsha engagement Hin 2015-02-07 10:12:13

After a period of time, the gearbox lubricant has abnormally increased gearbox noise, increased oil temperature, or behaved abnormally. The disassembly and unpacking inspection of closed gearboxes are cumbersome. Years of experience have sorted out the following analysis suggestions for reference:

I. Analysis and Suggestion of Fuel Tank Noise

1. The level and frequency of noise are affected by the following factors :

-The type of gear, the geometry of the tooth tip and root, and the finishing process of the tooth tip surface

-Lubricant selection and overall condition of mechanical lubrication

-Transmission load and speed

2.Noise reduction suggestions

-Check whether the axis is aligned and whether the installation is in place;

-Analysis of causes from noise and vibration frequencies;

-Check whether the oil can form an oil film, and whether the variability is high at high and low temperatures;

Second, the reason for the high temperature of gear oil

Regardless of the reasons of the machine itself, analyze the reasons for the high temperature of the gear from the perspective of lubrication:

(1) The load is large, the lubricating oil film is broken, and the failure tendency such as abrasion occurs, which causes the tooth surface temperature to be too high. At this time, it is recommended to replace oil with higher viscosity or higher extreme pressure performance.

(2) When the oil level is too high or the viscosity is too large, the stirring heat is increased, and the oil temperature and the tooth surface temperature rise simultaneously. It is recommended to lower the oil level or choose a low viscosity oil.
