Prevent damage of plane thrust ball bearing of improvement measures

Bearing damage caused by many reasons, such as improper installation, filth from invading as well or water intrusion is a common cause of early damage of many plane thrust ball bearing. Bearing and the corresponding analysis of the causes of the common damage can extend the life of the bearing of preventive measures. Improper operation, improper installation, operation, or remove the bracket will be may cause deformation or defect in the insufficient lubrication, lubrication inadequate or inappropriate may result in components abrasion or serious deformation of bearing rust and corrosion: contact with water can lead to erosion and rust plane thrust ball bearing components. After corrosion damage of bearing can lead to spalling at work: current bearing rotates the electricity may result in a groove or notch. Bearing static, electrical grounding improper operation will lead to a slight burn external material: intrusion can lead to wear and tear 'particle pollution and debris plane thrust ball bearing face eccentric wear, abrasion and sag, eccentricity, inclination, or excessive load geometrical stress concentration or the surface spalling failure may not be able to handle. Replace the former plane thrust ball bearings and grease, adjust bearing clearance, axial clearance is 0. 003 mm, radial clearance and 0. 002mm； Homemade improvised tool, manual grinding bearing inner taper hole, the surface with coating inspection, to ensure the handle and the bearing centering taper hole of contact area is more than 85%; Replace the disc spring. To fix the bearing to back bearing box, radial runout were examined with a dial indicator, proximal less than 0. 006 mm and 150 mm distal less than 0. 010mm。 Bearing temperature rise and noise to normal processing, processing accuracy satisfies the requirement of processing technology, troubleshooting. ( 3) Improvement measures: (1) increase the fine filtration and drying device, compressed air filters regularly drainage, clean or replace filter on a regular basis; 2) check the plane thrust ball bearing cone hole, the handle of the cleaning and cooperate with the condition, check whether the air dryer work normally; (3) reasonable arrangement of process, the abrupt change to avoid the material removal rate; (4) it is strictly prohibited to overload operation, defective shall promptly repair service, shall not be run in spite of illness.
