The
non-lubricated bearing has the characteristics of high bearing
capacity, impact resistance, high temperature resistance, strong
self-lubricating ability, etc. It is especially suitable for occasions
that are difficult to lubricate and form oil film, such as heavy load,
low speed, reciprocating or swinging, and is not afraid of water rush
and other acid liquids. Erosion and erosion. Non-lubricated
bearing products have been widely used in metallurgical casters,
rolling equipment, mining machinery, molds, lifting machinery, textile
machinery, wind power generation, ships, steam turbines, hydraulic
turbines, injection molding machines and equipment production lines. The wear resistance is twice that of ordinary bushings.
The superior performance of non-lubricated bearing materials:
1. Extremely high wear resistance, extremely low wear rate
2. Good self-lubricating performance, low friction coefficient
3. High impact strength and good toughness.
4. Excellent chemical resistance, resistant to almost all acid and
alkali salts (except concentrated sulfuric acid, concentrated
hydrochloric acid, a few organic solvents)
5. Non-toxic, odorless, no exudate
6. With elasticity, shock absorption; good self-restoration, low water absorption
7. Good mechanical performance, able to withstand large impact and
load, due to its excellent toughness, can effectively protect other
components from mechanical damage
8. Excellent low temperature resistance, even at -176 °C, it is not brittle.
The aging of the lubrication-free bearings looks for causes from these four places:
1. The strong vibration is caused by the strong vibration of the unlubricated bearing due to the failure of the motor core. This situation occurs because we want to replace the new non-lubricated bearing of the same model.
Second,
the reason for over-tightening is that the clearance between the ball
and the slideway is too small, the torque becomes large, and the
friction increases, resulting in the operating temperature of the
lubrication-free bearing being too high. Therefore, when installing, try to adjust the correct radial clearance of the lubrication-free bearing.
Third,
the material fatigue is due to fatigue of metal materials,
non-lubricated bearing raceway and debris off the ball surface fall into
the grease, resulting in increased operating noise. Therefore, we should consider the normal fatigue of non-lubricated
bearing materials and replace the new bearing of the same type.
Fourth, pollution corrosion, check the surface of the raceway and the ball whether the red, brown spotted corrosion.
Non-lubrication
bearing processing roughness: Regarding the impact of hardness and
processing roughness, non-lubricated bearings and steel shafts have a
tendency to increase the sliding sound when the roughness is large, but
the material of the non-lubricated bearings is relatively soft, so the
sliding surface will make the rough surface It
is deformed and flat. Therefore, its influence is not great. The
material of the steel shaft is hard, and when the surface of the makeup
is rough, there is no change, and its influence is considerable.
