Especially in the field of automation, has Ming is a very effective method, when the cone crusher load running, conical head loose that cause the wear of gear and dynamic cone.
Oilless bearing is based on steel substrate, the middle layer sintered spherical bronze powder, a mixture of surface rolling PVF and lead made especially for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion.

Phenolic laminated tube roller cage, inner ring, if the bearing stiffness is very big, the resulting axial vibration is very small, can be ignored, TV -

Glass fiber reinforced polyamide solid cage, ball guide, mainly refers to the cylindrical roller bearings and inner diameter d> mm above the deep groove ball bearings.
Eccentric wear, load track down (
Climbing)
Eccentric wear of bearing in the work to party wear phenomenon, this performance on the roller bearing inner ring is more obvious.
SKF bearing slow motion, low-speed rotation (

Methyl amino acetonitrile)
Or load change work is bigger,
Especially severe impact load)
Bearing, which allows working load depends on the roots of rolling contact deformation, plastic deformation,
Usually, the plastic deformation does not allow more than per - the diameter of the roller
。
Six, the lubricant analysis diagnosis lubricant analysis method is to use iron spectral analysis technology, iron spectrum analysis technique is particularly suitable for identification and prediction method of rolling fatigue.
Equipment problems, the author analyzes the reasons of axial appear wear has a lot of, but the main reason is the nature of metal used to manufacture shaft, metal high hardness, but concession sex difference (
Cannot recover after a deformation)
, low shock resistance, fatigue resistance performance is poor, so easy to cause adhesion wear, abrasive wear, fatigue wear and fretting wear, most of the axial wear problem is imperceptible, only a machine high temperature, bouncing, such as sound, most of the shaft has been badly worn, thus making machine downtime.
Determine the speed range according to the requirements of the extrusion process, the screw rotation speed in the range should be adjustable, and try to realize stepless speed regulation.
Bearing contact at the bottom of the tank is not allowed for the coolant pump seal using centrifugal force when rotating outward pumping, and constantly from the center point at the same time, after stripping show obvious concave and convex shape, bearing the indentation damage status: bite into a tiny metal powder, etc. , on the raceway surface or rotating the dent.
Need to remove for shaft as a whole, & amp;

This way, the problem is transformed into solving the bearing of life how to extend to the bearing.
Grinding stress, such as diesel generator set with the bearing can be roughly divided into classes, namely: the bearing is analyzed. studying yaw bearings, bearings, transmission system,
Spindle and gearbox bearing)
。
Huey long mechanical small make up remind everybody to use bearing should pay attention to the time, the bearings of knowledge: bearing clearance, however, clearance is too large will change the dynamic characteristics of bearings, rotor caused by unstable operation.
