How is the KAF37 reducer lubricated?

There are also corresponding conditions for the lubrication of K series gear reducers, and the lubrication conditions for different reducers are also different.

When the circumferential speed of the gear of the gear reducer is 12m s, oil injection lubrication should be used, that is, the oil pump or the central oil supply station is supplied with oil under pressure, and the lubricating oil is sprayed on the meshing table of the gear tooth by the nozzle.

When V 25 m s, the nozzle can be located at the tooth meshing edge or the whistle edge. When the v>25m s, the nozzle should be located on the side of the tooth whistle, so that the lubricating oil can be used to cool the newly meshed tooth in time, and at the same time lubricate the tooth. -Bench reducer.

It is very convenient to add lubricating oil to the reducer, and there are special oil injection holes and oil drain holes. I recommend regular lubrication.

This is a highly technical question for you, and you need to be answered by Great Wall lubricant experts.

Taiwan reducer: In order to improve efficiency, the worm gear reducer generally uses non-ferrous metal as the worm gear, and the harder steel is used as the worm, because it is a sliding friction transmission, in the process of operation, it will produce higher heat, so that the thermal expansion between the parts of the reducer and the seal is different, so as to produce a gap on the mating surface, and the oil becomes thinner due to the increase in temperature, which is easy to cause leakage. There are four main reasons, one is whether the combination of materials is reasonable, the second is the surface quality of the meshing friction surface, the third is the selection of lubricating oil, whether the amount of addition is correct, and the fourth is the assembly quality and use environment.

1. Selection of lubricating oil and additives. The worm reducer generally uses 220 gear oil, and some lubricating oil additives can be used for the reducer with heavy load, frequent start-up and poor use environment, so that the gear oil is still attached to the gear surface when the reducer stops running, forming a protective film to prevent heavy load, low speed, high torque and direct contact between metals during start-up. The additives contain seal conditioners and anti-leak agents to keep the seals soft and elastic, effectively reducing lubricating oil leakage.

2. Establish a lubrication maintenance system. According to the lubrication work "five fixed" principle of the reducer maintenance, so that each reducer has a responsible person for regular inspection, found that the temperature rise is obvious, more than 40 or the oil temperature is more than 80, the quality of the oil decreases or the oil is found in more copper powder and abnormal noise and other phenomena, to immediately stop the use, timely maintenance, troubleshooting, replacement of lubricating oil. When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated.

The correct use of lubricating oil plays an extremely important role in improving the operating performance of the unit, prolonging the service life of the unit, and saving economic expenses. Therefore, it is necessary to pay attention to the following when using it.

1) Regular inspection and timely replacement.

With the passage of time of the machine, the lubricating oil in the refrigeration system will continue to change qualitatively, so regular sampling and laboratory analysis, or color and phase comparison inspection, when the oil quality changes to a certain extent, it should be replaced in time. Under normal circumstances, the lubricating oil in the refrigeration system should be changed once a year.

2) Oil change requirements.

Look for the brand of new oil change, it is best not to easily change the brand of refrigeration oil, and it is strictly forbidden to use general engine oil instead of refrigeration oil.

Before replacement, all the oil in the system is released, and some new oil is added, and all the old oil remaining in the system is washed and released, so as to prevent the original oil from destroying the performance indicators of the new oil and affecting the service life of the unit.

When changing the oil, try to drain the remaining oil from the oil cooler. Thoroughly remove sediment and rust in the oil tank and air extraction device, and disassemble, inspect and clean the oil pump and filter to ensure that the replaced lubricating oil is clean and pure, and well lubricated.

3) Precautions to be taken when using the product.

During the shutdown of the unit, when the lubricating oil and refrigerant coexist in the system, the oil lubricating oil should be energized and heated to keep the oil temperature within the specified range.

In winter, when lubricants and refrigerants coexist within the system, how they are managed should be determined by the type of aircraft. Centrifugal chillers, especially centrifugal chillers with R11 as the refrigerant, should keep the electric heater energized to stabilize the oil temperature within the specified range. The screw and piston chillers can not be energized to the electric heater, and then turn on the power supply of the oil heater before use, heat for 24h, and then start the machine.

The fast ones are filled with low viscosity, the slow ones are filled with high viscosity, and the oil level is filled according to the display position required by the oil mask and so on.

Some do not have oil drain holes and use grease.

The lubrication of the reducer is also a very important part of the maintenance of the reducer. Open and semi-open gear reducer transmission, or closed gear transmission with low speed, is usually lubricated with oil or grease during the work cycle. The lubrication of the reducer also has its own conditions, and the lubrication conditions for different reducers are also different.

Let's take a look at how Shanghai Jinchuan reducer lubricates the gear reducer.

When the circumferential speed of the gear of the reducer is 12ms, oil injection lubrication should be adopted, that is, the oil is supplied by the oil pump or the central oil supply station at a certain pressure, and the lubricating oil is sprayed on the meshing table of the gear tooth by the nozzle. When V 25 m s, the nozzle can be located at the tooth meshing edge or the whistle edge. When the v>25m s, the nozzle should be located on the side of the tooth whistle, so that the lubricating oil can be used to cool the newly meshed tooth in time, and at the same time lubricate the tooth. To order a reducer, a bench reducer is a good choice.

I don't know what reducer you're talking about? Here's a general approach to home use:

It is recommended to measure the oil quantity in the state when the reducer is stopped and add an appropriate amount of worm gear reducer lubricating oil. Worm gear reducer manufacturers generally have instructions to standardize the oil volume of the worm gear reducer, and the oil quantity is added to the 2 3 position of the oil window. And this data is in a shutdown state, note:

Do not add lubricating oil while the worm gear reducer is running. Because in the process of worm gear reducer operation, its internal components gear or worm gear rotate to drive the internal lubricating oil to run together, if the amount of worm gear reducer oil is judged in this case, it may be full, it may be lower than the 2 3 of the oil window, and there may even be no lubricating oil.

We all know how to refuel the reducer, but in the daily use of the reducer, we should also pay attention to the cleaning of the reducer, especially the internal cleaning of the reducer, and the gearbox cleaning and maintenance machine helps us to clean the inside of the reducer to achieve good results and prolong the service life of the reducer. In addition, the gearbox cleaning machine can also be used to add new oil to the reducer, which can achieve a multi-purpose machine, which further reduces the cost of the enterprise.

Suzhou Chuanling answer: replace the lubricating oil, put the old lubricating oil clean, clean the inside of the reducer, it is best to replace the same brand and model must be the same lubricating oil (working at the same temperature)! Add lubricating oil according to the ambient temperature of the operation!

Outdoors, summer, more than 30 degrees, winter, below zero, different.

First of all, determine whether the type and grade of the lubricating oil are correct, drain the old lubricating oil, and add the required oil level of the new oil channel.

Suggested reducer for Taiwan machine:

1. The initial use of two weeks or 100-200 hours is the initial friction period, there may be a small amount of metal friction powder between them, please clean the inside, and replace the new lubricating oil.

2. When used for a long time, the lubricating oil should be replaced every six months to one year or 1000-2000 hours.
