Double row deep groove ball bearings, wear reasons and suggestions, as a result of wear and tear caused by the amount of material loss to wear. They can be obtained by measuring changes in length, volume, or mass, and correspondingly referred to as line wear, volume wear and mass wear. There are many reasons for the abrasion of double row deep groove ball bearings. The author makes the following detailed introduction.
1 ?improper use of bearings.
Reason: improper erection, operation or disassembly may cause deformation or defect of cage.
Recommendation: use proper handling, installation and removal tools.
2, inadequate lubrication
Reason: inadequate lubrication or improper lubrication may cause component abrasions or severe double row deep groove ball bearings.
Suggestion: improve lubrication system and replace lubricant properly and regularly.
3 rust and corrosion
Reason: contact water may cause erosion of pump shaft and bearing element and rust. Double row deep groove ball bearings after corrosion damage may cause spalling at work.
Suggestion: check the seal regularly, guarantee the good sealing effect, and correctly store the imported bearings.
4, current
Reason: turning on power may cause grooves or nicks. Double row deep groove ball bearings, stationary, improper electrical operation, grounding can lead to minor burns.
It is recommended to reduce or avoid current through the bearings before welding the parts other than the bearings.
5. External material
Causes: wear, particle contamination and debris intrusion may cause wear, galling and dents in the face of imported bearings.
Tip: clear the invading particles and debris, replace the lubricant, and check the sealing system.
6, eccentric
Reason: eccentric, inclined or excessive load may lead to geometric stress concentration or surface spalling.
Proposal: accurate processing of imported bearing blocks and shoulders.
Double row deep groove ball bearings after installation, in order to check the installation is correct, to carry out running inspection. Small machines can be rotated by hand to make sure the rotation is smooth. Check the project caused by foreign bodies, scars, indentation is dysfunctional, due to poor installation, mounting process arising out of the bad moment is not stable, because the clearance is too small, installation error, sealing caused by friction torque is too large and so on. If there is no abnormality, the power operation can start. |
