The purpose and method of maintenance bearing lubrication
For bearings，Lubrication is an important issue affecting its performance。The appropriateness of the lubricant or lubrication method will greatly affect the life of the bearing。
Lubrication：
1）All parts of lubricating bearings，Reduce rotary friction between the channel surface and the steel ball， Sliding friction between steel ball and cage， And sliding friction between the cage and the channel guide surface
2）Other heats from the internal friction generated by the bearing；Prevent bearing heat and lubricant deterioration
3）Make the rolling contact surface of the bearing forms a suitable oil film，Reduce the centralized stress of the impact load，Extend the fatigue life of the bearing。 4）Prevent steel ball corrosion， Dumulation and cage， And garbage invasion， foreign body， Moisture。Rust and dustproof。
Bearing lubrication is mainly divided into fat lubrication and oil lubrication。Overall comparison is as follows：
Grease lubrication
Fill once，No need to add grease to lubricate。Moreover, the structure of the sealing device is relatively simple.，therefore， It is widely used。
Oil lubrication has a sealing method，Among them, the oil is pre-filled in the sealed bearing.。And fill the right amount of grease in the housing，Regular supplementation and replacement of grease。
In addition，For mechanicals with multiple bearings that need to be lubricated，Also use a concentrated lubrication method for connecting grease to each lubricant point。
1）Injection
The amount of lubricating lipid filling in the housing varies with the structure and volume of the casing。usually， It is best to fill the volume1 / 3-1 / 2。
When the amount of fill is too large, the heat caused by the stirring causes the grease deterioration.，Aging and softening，It should be attracted。
But when used for low speed bearings，In order to prevent foreign matter invasion，Sometimes it will fill the volume2 / 3-1。
2）Supplement and replacement of grease
The supplementation and replacement of grease is closely related to the lubrication method。No matter what method, clean oil must be used.，And pay attention to prevent foreign matter invading。
Supplemental oil should be the same brand of fat。
易彤破壁机常见故障 Add oil，Ensure that the new grease does enter the bearing especially important。
Oil lubrication
Oil lubrication is suitable for high-speed bearing，And you can withstand a certain level of high temperature，It also effectively reduces vibration and noise，Usually used in applications that are not suitable for use of grease lubrication。
Oil lubrication is roughly divided into：（1）Oil bath lubrication（2）Drops（3）Splash lubrication（4）Cycle lubrication（5）Spray lubrication（6）Oil mist lubrication（7）Oil and gas lubrication。
Standard lubricant
Oil is a semi-solid lubricant composed of base oil， Adhesive and additive。Must be selected according to its combination of grease。
（1）Base oil
The base oil of oil is generally mineral oil，But in order to improve heat resistance and 易彤沙冰机维修 low temperature fluidity，therefore， Can also use synthetic oil，For example silicone oil。
（2）Tackifier
Adhesive includes various composites， Wait, control, such as mechanical stability， Water resistance And working temperature range。
（3）additive
According to the purpose of use，Add various additives。
·Pressure additive can improve impact load and heavy load characteristics。
·No time to supply for a long time，Oxidation additives prevent oxidative degradation。
·Anti-rust additive prevents bearing and its surrounding environmental corrosion。
（4）Viscosity
Depending on the degree of hardness of the oil，It refers to5Use the specified weight of the metal cone injects the depth of the grease using the specified weight of the metal cone.（use0。1mmPhysical 易彤破壁机售后网点 quantity，The greater the value， More softly。
（5）Dropping Point
The oil turns into liquid after heating，Temperature from the specified hole is referred to as dropping points，The higher the value， The higher the temperature。
（6）Heterogeneous oil mix
Touch and additives are mixed together，Changes of oil properties，therefore， In principle， It is best to avoid mixing different greases。
（7）Closed oil
（8）Lubrication life
（9）Gap replenishment gap
Even use of high quality grease， Due to long-term use and surroundings，The performance of grease is lowered，Low lubrication performance， Must supplement and replace grease in time。usually， The annual work temperature is about50℃Even100°CHave a good heat resistance，It is best to replace each year2to3Secondary。
Standard lubricants without special names are as follows：
