Purpose of IKO bearing lubrication:
The lubrication purpose of rolling IKO bearing is to reduce the Lubrication Of internal friction and wear of IKO bearing and prevent burning and sticking. Its lubrication effect is as follows.
(1) Reduce friction and wear.
In the contact parts of the ferrule, rolling element and retainer Lubrication Of constituting IKO bearing, metal contact is prevented and friction and wear are reduced.
(2) . prolong fatigue life.
The rolling fatigue life of IKO Lubrication Of bearing is prolonged when the rolling contact surface is well lubricated during rotation. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.
(3) Discharge friction heat and cooling.
The circulating oil supply method can use oil to discharge the heat Lubrication Of generated by friction or the heat transmitted from the outside for cooling. Prevent overheating of IKO bearing and aging of lubricating oil.
(4) , others
It also has the effect of preventing foreign matters from invading the interior of IKO bearing, or Lubrication Of preventing rust and corrosion.
The lubrication methods of IKO bearings are divided into grease lubrication and oil lubrication. In order to make IKO bearing Lubrication Of function well, firstly, the lubrication method suitable for service conditions and purpose should be selected.
If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the surrounding Lubrication Of structure of IKO bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.
Fag bearing corrosion is mainly divided into metal corrosion and human hand sweat. Metal corrosion accounts for the vast majority and can not be avoided in many cases. Hand sweat can also cause corrosion of fag bearings, mainly because sweat film will be generated on its surface when sweat contacts,
and electrochemical reaction will occur during interaction, which can lead to corrosion, but it can be avoided, such as wearing Lubrication Of professional gloves and other tools to take parts.
Metal corrosion mainly includes:
① Surface finish; ② Chemical structure and composition of metal materials; ③ Solution composition and pH value of metal surface; ④ Environmental media; ⑤ Ambient humidity and temperature.
Rust prevention pretreatment method:
Keep the surface clean and use appropriate methods for cleaning. General chemical treatment cleaning, mechanical cleaning and solvent cleaning. After the surface is cleaned, it can be dried with dry compressed air or with a dryer at 120 ~ 170 ℃, and then wiped with clean gauze.
(1) spray method
For example, some large antirust substances cannot be oiled by immersion method, which is mainly applicable to thin-layer antirust oil or solvent diluted antirust oil, but pay attention to labor and fire protection measures.
(2) Brush coating method
When brushing, it is not only necessary to avoid accumulation, but also to prevent coating leakage. It is generally applicable to some special shape products or outdoor construction equipment that are not suitable for soaking or spraying.
(3) Immersion method
The oil film thickness can be achieved by controlling the temperature or viscosity of antirust grease. Some small items are soaked in antirust grease to make their surface adhere with a layer of antirust grease.
