Analysis of the problem of gear vibration of Calcium Carbonate Grinding Machine

 The Calcium Carbonate Grinding Machine is the key equipment for crushing the material after it has been crushed. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings and glass ceramics, dry or wet grinding of various ores and other grindable materials. The Calcium Carbonate Grinding Machine is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to different mining methods, it can be divided into two types: grid type and overflow type.

 
 

 The vibration of the Calcium Carbonate Grinding Machine gear sometimes causes the teeth of the large and small gears to be bad. Moreover, the wear of the couplings and the motor bushings is accelerated, and the life is shortened. In severe cases, the motor is burnt, etc. accident. Therefore, researching and analyzing the causes and finding out the improvement measures are the problems that Calcium Carbonate Grinding Machine manufacturers should consider.

 

1. Manufacturing aspects

 The gear profile of the Calcium Carbonate Grinding Machine drive gear is involute tooth shape. The main defects caused by the standard installation are: eccentricity, pitch error and tooth shape error. These defects make the gear pair easily cause other faults during operation. However, since these factors are determined before leaving the factory and cannot be changed, they can only be strictly checked and accepted according to relevant standards at the time of purchase.

 
 

2, installation aspects

 

 According to the relevant literature, the coincidence degree, head clearance and backlash, modulus of the meshing gear have an important influence on the working performance of the gear, and the coaxiality error between the axis of the motor main shaft and the pinion gear during the installation process, The parallelism error between the pinion axis and the large gear axis exceeds the error range, the flank clearance and the tip clearance are not equal in the full tooth width, and the coincidence degree is small, etc., all of which affect the correct meshing of the gear teeth. Shock and vibration are generated in the middle.

 

3, lubrication

 The Calcium Carbonate Grinding Machine transmission gear pair is manually lubricated. An oil groove is opened in the gear guard portion directly above the gear pair meshing zone, and a gap for lubricating oil is opened at the bottom of the oil groove. The operating personnel periodically fills the lubricating oil, and the lubricating oil passes through the cotton yarn in the middle of the gap. Drip into the gear meshing area to complete the lubrication task of the gear pair.
