How to carry out the daily maintenance and maintenance of reducer, speed reducer lubricating oil used in general what standard, what is lubrication reducer, here we introduce on these issues, let users can know the reducer should be how to maintain the speed reducer and our equipment, give you a professional reference and suggestions.

The reducer generally selects GB5903 medium load industrial gear oil L-CKC220 and L-CKC320.. The table below shows the viscosity of the lubricating oil (mineral oil) recommended by the reducer at different environmental temperatures.

A. oil level

The gear reducer is usually lubricated with oil gear. It must be supplied to the required position (according to the indicated position) before being used and replaced regularly.

B. oil change cycle

When the new reducer is used for the first time, the new oil must be replaced after the running period of 7~14 days (150~300 hours). 3 months to use, second new oils must be replaced. In the future use process, and regularly check the oil quality, must always replace containing impurities, pollution, or decomposition, aging of the deterioration of oil. Under normal circumstances, long-term continuous work of the reducer can be 6~8 months should be replaced oil, and the daily work of not more than 8 hours of reducer, 10~12 months can be replaced.

C. oil

The new oil changed must be the same as that of the original brand, and should not be mixed with different grades and different types of oil.

Before injecting the new oil, heat the oil of the same type as when it is running, then use it to clean the gear.

2. lubrication method

Reducer generally use oil tank lubrication, natural cooling.

When the working temperature of the reducer is over 900C or the carrying capacity exceeds the heat power PG1, the circulating oil lubrication can be adopted, or the oil circuit with the cooling pipe can be used for lubrication.

When the gear reducer is stopped continuously for more than 24h, the gears and bearings should be fully lubricated at the start, and the load can be run normally.

3. bearing lubrication

Lubrication of rolling bearings in reducer, two kinds of lubricant are often used: lubricating oil and lubricating grease.

When choosing lubricating oil, the factors such as bearing load, speed, temperature and working environment should be taken into account. The higher the load and the higher the temperature of the bearing, the higher the viscosity of the lubricant used. Small load, low temperature and high speed can be used in small viscosity lubricants.

Too much or too little oil in the bearings will lead to overheating of bearings. When the bearing speed is n=1500r/min, the oil level should be lower.

In the bearing rotation, the ring speed is not greater than 4-5m/h, grease lubrication can be used. When using grease lubrication, the amount of grease in the bearing can occupy 1/3-1/2. of the bearing chamber space

Lubrication method of rolling bearing in reducer can use lubricating oil directly in the oil tank of reducer, at this time, the lubricating oil in the oil tank of the gear reducer must be introduced into the bearing.

4. maintenance and maintenance

4.1 spare parts manufacturing

The speed reducer should be checked and repaired regularly. Effective measures must be taken to detect scuffing, scuffing and significant wear. The spare parts must be manufactured according to the standard, and the updated spare parts must be used for running and load test before they can be used formally.

4.2 drive check

The speed reducer should be checked and repaired regularly. Effective measures must be taken to detect scuffing, scuffing and significant wear. The spare parts must be manufactured according to the standard, and the updated spare parts must be used for running and load test before they can be used formally.

4.3 oil temperature

Always check bolt fastening degree and oil quantity. The oil level of the reducer is lower than the lower scale of the vernier gauge, and the oil should be added in time. Cycle oil lubrication should pay attention to elegant changes. When the oil pressure is obviously lower, the cleaning oil filter net shall be checked.

4.4 heat check

In order to reduce the heat dissipation of the reducer, the outer surface should be kept clean and the air vent shall not be blocked. If the box heating up too high, should check whether the oil level is too high, whether the surrounding heat conditions are not good, oil aging, or cooling water is not enough, cooling coil fouling, cooling effect is not good and so on.

4.5 oil spill check

If the high speed oil leakage is found, check whether the oil level is too high. If the seal is damaged by aging or wear, it can be injected into the proper butter through the butter tip on the cover. If the oil leakage is serious, the user should replace the oil seal in time.

Important: after 8 hours of operation of the reducer, a small area of oil soaked in the vicinity of the seal is impervious to oil, the oil area is expanded, and the base is oil seepage, and the accumulated oil level is leaking on the foundation

4.6 safety protection

The rotating part reducer leakage should shelter and motor or other electrical equipment should be grounded connection

Important: do not unload the test cover during the operation of the gear reducer so as to avoid personal injury caused by high temperature gear oil splash.

4.7 oil change

In normal operation, metal micro material inevitably enters the oil due to the continuous operation of the surface. The dirt will shorten the life of the bearing and lead to premature retirement of the gear, so it is necessary to maintain the oil by frequent replacement of the oil.

4.8 system management

Users should have reasonable use and maintenance rules and regulations, the operation of the reducer and the problems found in the inspection should be carefully recorded.

Important note: if the user to install and use of reducer are not familiar with, but because of the need for maintenance necessary to remove a host device or reducer, please inform our company for technical support or consent of our company. In case of damage caused by improper use of gear reducer or other equipment due to unauthorized loading and unloading of users, the responsibility of the coating shall be borne by the user.
