Open gear lubrication system

Open gear lubricating oil is a common transmission method in the raw material processing industry. It is widely used in large-scale equipment in electric power, mining, cement, steel, chemical, paper and other industries, such as: ball mill, tube mill, rod mill, rotary kiln, Dryer, granulator, drum pulper, etc.
The main features of the open gear lubricating oil transmission are: heavy load, low speed, large structural size and high tooth surface roughness, and harsh working conditions (such as dust, high temperature, impact load, etc.), which can transmit high force and Torque (some double-tooth drive units can achieve >2×5000KW transmission power), so the tooth surface is subjected to extremely high stress, and the open gear oil is meshed in addition to the rolling friction at the pitch position. There is also a large amount of sliding friction in the process. The open gear lubricating oil is usually in the mixed friction state (starting, stopping, excessive shearing force, impact load, etc.), so the lubrication condition is very harsh, and the ideal lubrication is needed. Protection, extending gear life, reducing spare parts loss, downtime loss, and improving equipment stability require proper open gear lubricants and reasonable lubrication methods and methods.
If the open gear oil used in the open gear is not selected due to the conditions, the open gear lubricant that fully meets the above conditions will not be selected, which will result in a lot of manpower and material resources, but still not up to To the ideal lubrication state of the open gear, the consumption of the oil is huge, and the gear will still have problems such as excessive wear, plastic deformation, pitting, peeling, and more serious chipping. For the open gear, it is the most prone to occur. The problems are scratches, plastic deformation, pitting, flaking and abrasive wear.
The working condition characteristics of the open gear determine that the open gear lubricating oil used must have good adhesion performance, extreme pressure anti-wear performance, impact load resistance, and can resist high temperature and water erosion depending on specific operating conditions and environmental requirements. It has strong sealing, reduces the influence of dust, spray performance, flowability, and does not contain heavy metals and substances that may damage the environment and human body.
Choosing the right open gear lubricant is the first step to ensure that the equipment can be well lubricated. It is necessary to comprehensively consider the relevant factors according to the working conditions and design characteristics of the equipment before it can get an accurate judgment, mainly based on the load of the equipment. Temperature, environment, speed and lubrication method.
The new open gear open gear lubricant thickens the high viscosity oil containing solid lubricant with a composite thickener. The thickener here has a very good adhesion to the oil and will not easily fall off the small teeth. It has good extreme pressure and anti-wear performance. It contains solid open gear lubricating oil to ensure the boundary lubrication performance and emergency lubrication function of the oil. It does not contain asphalt and solvent (harmful to the environment and human health). Leakage has become more and more recognized and recommended by many manufacturers, especially in Europe. Therefore, based on the aforementioned lubrication maintenance viewpoint, most of them use the lubrication method of spraying small teeth.
