SKF Bearing Clearance:
SKF Bearing Clearance refers to the movement of SKF Bearing when one Clearance Measurement side of its inner ring or outer ring is fixed when it is not installed on the shaft or bearing housing, and then the unfixed side moves radially or axially.
Generally speaking, SKF Bearing Clearance Measurement rotates for a long time, stops slowly, and has good sensitivity. On the contrary, if the rotation time is short and the suspension is sudden, the sensitivity is not good. According to the moving direction, it can be divided into radial clearance and axial clearance.
The measurement of radial clearance of SKF Bearing is not simple. The Clearance Measurement measuring force of imported bearing causes elastic deformation of the ferrule, the rolling body itself and its touch.
The amount of deformation is a multi-element constituting the Clearance Measurement measurement error, which is related to the measuring force, the touch condition and the orientation of the rolling body.
The rotation sensitivity of SKF Bearing is generally checked in the horizontal direction. The inner ring is usually fixed and the outer ring is rolled by hand to check whether there is Clearance Measurement abnormal movement, static and blocking during the rotation of SKF Bearing.
Due to the different structural types and dimensions of SKF bearings, Clearance Measurement there should be different requirements for their rotation sensitivity.
For example, single row centripetal ball bearings and single row Clearance Measurement centripetal thrust ball bearings, these SKF bearings are relatively light and agile when rotating because of the small touch area between the tumbler and the ferrule,
while double row centripetal spherical bearings and thrust roller bearings, Clearance Measurement because the touch area between the tumbler and the raceway is large and the component of the outer ring is small, although a certain load is added to check their rotation sensitivity,
However, its lightness and agility level is still lower than that of single row Clearance Measurement radial ball bearing.
1. First, put the SKF imported bearing into gasoline for cleaning and wipe off the oil sludge and dust remaining on the SKF imported bearing. All rusty Clearance Measurement SKF imported bearings are quietly scrubbed and polished with gold sandpaper until there is no roughness by hand.
2. Wipe the cleaned SKF imported bearing dry with dry rags, and then soak it in antirust oil. In this process, the SKF imported bearing shall be completely touched with the anti rust oil of the imported bearing, and the SKF imported bearing shall be rolled continuously,
so that the oil film composed of anti rust oil can be covered on the surface of the SKF imported bearing to achieve the purpose of anti rust.
3. Next, apply lithium grease and butter evenly on the surface of SKF imported bearing, including inner and outer rings, wheels and holder. And the SKF inlet bearing is rolled while wiping, so that the butter can really enter the SKF inlet bearing and play a full and smooth role.
Bearing discoloration. When the bearing operates under continuous high temperature, it will produce black or blue. The main reasons for bearing discoloration are: the lubrication in the bearing does not meet the technical requirements;
Dirt or impurities invaded during bearing installation; The fit of the bearing with the journal and shaft hole is loose, resulting in sliding friction between the inner and outer rings of the bearing; The non concentricity between the bearing seat hole and the journal leads to abnormal effects on the bearing during operation;
The bearing operates its own designed bearing capacity due to overspeed or overload operation; The axial clearance of the round cone roller bearing is small, and the bearing has large friction with the sealing device, washer and bushing.
The inner and outer rings of the bearing are cracked. There are different degrees of cracks on the inner ring and outer ring of the bearing, mainly due to:
defects in the quality of the bearing or defects in the steel used by the bearing; The shaft bears large external impact load; When installing and removing the bearing, the bearing bears the direct beating of iron, resulting in cracking of the inner and outer rings of the bearing;
The inner ring, outer ring, seat hole and Journal of the bearing are poorly matched, resulting in uneven stress on the raceway and cracks on the inner ring and outer ring.
