To prevent rusting of the bearings: directly with the hand take bearing, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust.
Enterprise equipment problems and analysis equipment parameters: the ball mill mm shaft diameter, bearing width mm, bearing type mm/CA/W bearing a unilateral wear;
Equipment problem: long running process, due to the bearing life cycle is too long, the bearing itself appear wear away, clearance is too large, medium oil film lubrication process to protect the bearing lubrication, at the same time, seal damage internal material dust into the bearing, bearing rolling friction increases, the normal operation of the serious influence bearing, lead to bearing operating temperature is too high, cause bearing sintering lock, and progress lead to bearing inner ring and relative rotation axis.
Choose suitable for the rolling bearing grease when choosing suitable grease, often need to consider the following factors: the type of bearing, speed, working temperature and load, and the installation location, sealing, shock and vibration, as well as the consideration and the environmental protection requirements.
Electrical protection -
—
Overload protector (
Quick fuse overcurrent relay)
Mechanical protection -
—
Safety pin or security key, when overload, first cut pin or keys, protection.
According to its work when whether bearing, is divided into: self-aligning bearing -
-
-
-
Raceway is spherical shape, can adapt to the Angle between the two raceway axis deviation and angular motion bearing;
The self-aligning bearing (
Rigid bearing)
-
-
-
-
Can the impedance between the raceway bearing axis Angle deviation.
Acceleration type test method of the bearing vibration measuring instrument installation method as shown in the specified test conditions, the bearing running period of time to get the stable bearing vibration state, corresponding to each measurement location in some state of bearing vibration value.
After the shearing action to stop, it can restore consistency, the mobility of the special grease, decide it can be not suitable for using the part of the lubricating oil lubrication.
Heat treatment: heat treatment equipment closely monitor is important work, workshop for instrument, thermocouple and other important thermostats must be closely monitored, ensure measured data accurate and reliable;
The error exceeds bid to timely replacement, no band operation.
Can use all the rolling bearing grease, but must pay attention to the manufacturer's instructions for grease!
The complement of the grease is usually in six months or years for replacement, replace the old grease should be removed before to change the new grease.
During the transitional period, these figures will only be used for example: NUM, more and more choices now skateboard brand too much, a lot of bearing under different brands, what is the sample.
Bearing under the action of load, inner ring circumferential crumbling, produced by the rotation of outer ring only in the short axis symmetry position crumbling, this is the main reason of premature failure of the bearing, the test showed that the failure parts of the bearing the bearing outside diameter roundness is from the original process control.
Kind of love, a true sometimes even heavier than the weight of the world, assembly in place after remove extrusion of restorative materials with scraper, good before curing materials do not move components.
