Rolling bearing using a variety of mechanical equipment, bearing conditions required by the increasingly stringent market requirements of equipment and other properties, the performance also increasingly diversified.
From a large number of structure, size, select the most appropriate FAG bearings, need a different Angle.
Bearing the choice, it is generally believed that as one of the bearing, the difficulty of installation and removal, bearing, market size and outer spherical bearing, such as space allows, generally defines the structure of the bearing.
In the use of a variety of mechanical design life and comparative study of limit bearing of durable bearing, bearing has to be decided at the same time.
In selecting bearings, bearings are often inclined to think that grease life in aging, the fatigue life of oil, abrasion resistance, low noise, also need to fully research.
In the process of using FAG bearing, special for outer spherical bearing lubrication, to pay more attention to the amount of grease.
How accurately using grease and ask you must understand the grease in the bearing 6316 -
In the 2 rs movement status to ensure the stability of the grease.
Fill in the rolling bearing grease movement, follow the changes of bearing, generally can be divided into two stages.
In popular conditions, FAG bearing grease filling amount, in always goes beyond the practice demand directly involved in the lubrication, full frame and bearing cover of the cavity, and an outline is made in the rolling around in vitro.
In the process, because of excess grease resistance, bearing temperature rise quickly.
Although most redundant grease at the beginning of the operation is being squeezed out, and squeezed in the raceway attachment grease could still be migration transformation between the rolling element into the race.
The outer spherical bearing the early stages of the operation, most of the grease quickly (
Less than a minute)
Is being squeezed out of raceway and accumulate in bao followed the bearing grease migration body cycle also, have a small amount of discharge.
Bearing (degrees still continues to rise at this moment, until all redundant grease were discharge, may be called the grease running-in stage, according to the structure of the bearing grease, filling quantity elements such as quality, this paragraph of time may last ten minutes, and even a few hours.
At the time of filling grease resistance to friction FAG bearing, may not need to use the theory of high pressure, unless very careful to use.
High pressure can damage the bearing, waste grease, excessive grease caused by high temperature dangerous and surrounding the FAG bearing invisible environment.
In most applications, the ball or roller bearing lubrication, if grease level accounted for a third to a half of outer spherical bearing capacity.
Beyond the amount of usually will be sealed shell discharge and waste.
All FAG bearing friction resistance of the bearing basically contains two hardened steel rings, multiple hardening of ball or roller, roller or roller and a separation or maintaining aircraft separation.
These types are in use is divided into many types.
Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement.
Bearing maintenance and judgment: to determine whether remove bearing can be used to check the bearing after cleaning.
Check the raceway, raceway, surface state, cage wear, outer spherical bearing clearance and to increase the dimension precision, has not damage, abnormal.
Non separation of small ball bearings, inner ring, with one hand support level, rotate the outer ring to confirm smoothly.
Bearing separation type bearing, rolling your body, the outer ring raceway surface inspection.
Large bearings, because they can't rotate with the hand, pay attention to check the raceway of roller and cage, metope, such as appearance, the importance of higher FAG bearings, check more carefully.
