Mud agitators are indispensable in drilling fluid configuration. The mud agitator adopts the circular arc cylindrical worm reducer, the shaft section is a circular arc cylindrical worm, and the worm gear tooth shape is a circle that is conjugative to the worm. Therefore, the convex-concave meshing performance is reliable, the benefit is high, and the structure is compact.

The circular arc tooth of the mud agitator reducer in the mud agitator is a kind of mud agitator part that can often be seen. It has great advantages in structure and transmission, especially in special environments. It has the function of automatic locking, so it is liked by many solid control manufacturers. 

Among the arc reducer faults, the following three are more common:

The first type: the oil leakage of the reducer.

The second: the wear degree of the reducer worm gear.

The third type: damage to the reducer bearing.

The relevant solutions are as follows:

The first type: oil leakage of the reducer:

1: Heat and oil leakage of the arc reducer. The arc gear worm gear reducer is designed for the purpose of improving the operation efficiency. The worm gears used are all made of non-ferrous metals, and the worms are mostly made of hard steel. Therefore, during the operation of the sliding friction drive, the worm gears are reduced. The machine will generate a large amount of heat and increase the temperature of the reducer. The temperature increase of the worm gear reducer will cause the various parts in the reducer to have differences in the fit due to the different coefficients of thermal expansion, resulting in a gap between the mating surfaces. The oil such as lubricating oil used in the reducer will also become thinner or deteriorated under the action of high temperature, resulting in leakage or lubrication failure. The way to prevent the temperature rise of the worm gear reducer is to reasonably match the material of the worm gear and worm to avoid excessive friction. At the same time, pay attention to the surface quality of the meshing friction surface and select suitable lubricants. Another direct way to cool the reducer is to install a cooling device or reduce the temperature of the operating environment.

The second: the wear degree of the reducer worm gear. 

2: The worm gear of the arc gear reducer is worn out. The worm gear of the worm gear and worm gear reducer generally uses tin bronze as the main material, and the worm is made of hard steel. The worm gear and the worm continue to generate friction during the operation of the reducer, and the worm gear with softer material Wear will occur due to the action of the worm. The wear rate of the worm gear reducer is very slow, which usually does not reduce the service life of the reducer. If the wear rate is fast, the selection, operation, material matching and lubrication of the worm gear reducer of the reducer should be considered. 

The third type: damage to the reducer bearing.

3: Damage to the worm bearing of the reducer. The damage to the worm bearing of the worm gear reducer is mainly manifested in the rust and corrosion of the bearing. The main reason for this problem is the lack of lubrication of the gear inwards, or the emulsification of the gear oil. After the worm gear reducer stops running, the gear oil will be emulsified due to the condensed water generated by cooling.
