the amount of material loss is called the wear caused by wear and tear. this can be achieved by measuring the change of the length, volume or quality and get, and called them accordingly, line wear volume and wear quantity and quality of wear.
double row deep groove ball bearings use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. according to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality in determining the quality of double row deep groove ball bearings, such as the three major factors.
1. use bearing improper operation.
reasons: improper installation, operation, or remove the bracket will be may cause deformation or defect
suggestion: use the appropriate operation, installation and removal tools
2. insufficient lubrication
reason: insufficient lubrication or may lead to improper components abrasion or severe deformation of double row deep groove ball bearings
suggestion: to improve the lubrication system, properly supplement or replace lubricant regularly
3. the rust and corrosion
reason: contact with water may lead to the pump shaft bearing components erosion and rust. after corrosion damage of double row deep groove ball bearings at work can lead to spalling
suggestion: regular inspection seal to ensure good sealing effect, correct storage import bearings
4. the current
reason: turns electricity may result in a groove or notch. double row deep groove ball bearing static, electrical grounding improper operation will lead to a slight burns
suggestion: outside of bearing parts with proper grounding connection to reduce or avoid before welding current through bearings
5. the external material
reason: wear particle pollution and debris intrusion can lead to import bearing surface wear, abrasion and sag
suggestion: remove intrusive particles and debris, replacement of lubricants, check the sealing system
6.eccentric
reason: the eccentricity, inclination, or excessive load may result in geometrical stress concentration or surface spalling
suggestion: precise processing imported bearing seat and retaining shoulder
double row deep groove ball bearings after installation, in order to check whether installed correctly, check for running. small mechanical can rotate with the hand, to confirm whether to rotate smoothly. check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. if there is no abnormal can start power operation.
