In
order to maintain the bearing's performance in good condition for as
long as possible, it is necessary to maintain and repair it in order to
ensure the reliability of the operation, to ensure the reliability of
operation, and to improve the productivity and economy. Maintenance of the best operating conditions of the corresponding mechanical operating conditions, regular. The
contents include monitoring the operating status, replenishing or
replacing the lubricant, and checking the inspection on a regular basis. As the maintenance of the operation, there are bearings of the
rotating sound, vibration, temperature, the state of the lubricant and
so on.
Bearing
cleaning: Remove the bearing repair, the first record of the appearance
of the bearing, to confirm the amount of residual lubricant, sampling
inspection with the lubricant, the washing bearings. As a cleaning agent, the general use of gasoline, kerosene.
Remove
the bearing cleaning, sub-rough cleaning and fine cleaning,
respectively, placed in the container, first put the metal bottom of the
net, so that the bearings do not directly contact the container dirt. Rough cleaning, if the bearing with a dirt rotation, will damage the bearing rolling surface, should be noted. In the rough cleaning oil, use the brush to remove the grease, sticky material, roughly clean, into the fine wash.
According to the effect of the load on the bearing, the ring rotation
of the situation, the load can be divided into fixed load, load shedding
and back and forth shaking load three.
Fixed load
The
combined radial load is borne by the area of the ring raceway and is
correspondingly transmitted to the corresponding part of the area of
the shaft or shell. This kind of load the Swedish bearing is called the fixed bearing load.
The unique place of the fixed load is that the synthetic radial load is relatively stationary with the ferrule. Bear the fixed load of the ring can be used to choose the more appropriate loose.
B. Turn off the load
The
synthetic radial load vector applied to the bearing collar rotates in
the circumferential direction of the raceway, which is carried by the
various parts of the raceway and is transmitted to the various parts of
the outer surface of the shaft housing hole. This load is called the turn load, also known as the cyclic load.
The unique place to turn off the load is to synthesize the radial load vector relative to the ferrule. Bear the load of the ring with the shaft or shell hole should be used over the shower or interference appropriate. If
you think fit and use the appropriate installation of the gap, you and I
will be issued between the phenomenon of delivery, which will cause
contact surface friction, friction heat, so that the rapid increase in
temperature, bearing quickly destroyed. The size of the coinage is determined by the fact that the bearing
does not allow the ferrule to be exposed to the proper appearance of the
shaft or the casing hole, depending on the operating conditions.
The
combined radial load vector applied to the bearing rings is relatively
shaken back and forth within a certain area of the ferrule, for a
certain area of the raceway and transmitted to a certain area of the
outer surface of the shaft or shell , Or the effect of the load on the bearing is the impact load, the
oscillation load, its load direction or the number of people often
change, this load is called back and forth rocking load, also known as
not the direction of load.
Bearings
bear the shaking load back and forth, especially in the burden of
charge, the outer ring should be considered appropriate and the use of
appropriate interference. When
the inner ring is swung back and forth, it is appropriate to use the
reverse load when the inner ring is considered suitable. However,
sometimes the outer ring must be able to outside the shell to the
bearing to the swimming or its load is lighter, can be considered
appropriate and the use of the load slightly more appropriate than the
switch.
