 lubrication

 

The rolling bearing lubrication has reduce bearing internal friction and wear, prevent burning stick; Prolong the service life; Discharge frictional heat, cooling, prevent hotbox, prevent the aging oil; Also has to prevent foreign matter into the bearing internal, or to prevent rust and corrosion.

The lubrication methods

Bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. To pay special attention to the dosage, lubricating oil or grease lubrication, too little quantity insufficient lubrication, affecting the service life of bearing too much will produce large amount of resistance, impact speed.

seal

 

Bearing seal can be divided into two categories, own seal and seal. The so-called bearing with seal is made bearing itself into a sealing device. Such as bearing with dust cover, sealing ring, etc. This seal take up the space is small, easy installation and disassembly, cost is low. Alleged bearing and sealing device, it is inside the installation end cover manufacturing into a sealing device has a variety of performance. Bearing and seal is divided into the non-contact seal and contact seal. The non-contact seal is suitable for high speed and high temperature occasion, such as clearance type, labyrinth and gasket type different structure forms. Contact seal is suitable for the medium and low speed working conditions, commonly used have felt seal, cup sealing structure, etc.

According to the bearing working condition and working environment requirement for sealing on the engineering design is often integrated use of various seal form, in order to achieve better sealing effect. The choice of bearing and seal should consider the following several major factors:

Bearing lubricant and types (grease and lubricating oil);

The size of the bearing work environment, take up the space;

Shaft supporting structure advantages, allowing the angular deviation;

The circumference of the sealing surface speed;

The working temperature of bearing;

The manufacturing cost.
