Corrosion damage to the bearing after the task can lead to peeling deep groove ball bearings
Smooth enough: Smooth enough or wrong to be able to incur parts abrasions or significant bearing deformation
Operation error: device, operation or assembly errors can cause deformation or deformation of the cage
Bearing damage caused by many reasons, such as device error, dirt invasion or moisture intrusion is a lot of three-dimensional thrust ball bearing a rare cause of late damage.
Fair: Fair, skewed or excessive load can lead to the number of what the set of stress or nominal spalling
Internal talent: abrasive particle purification and debris intrusion can lead to three-dimensional thrust ball bearing task surface wear, abrasion and bulge
Direct current: The bearing can turn into a groove or notch when it is turned.
. Change before the three-dimensional thrust ball bearings and smooth grease, to mobilize the bearing clearance, axial clearance 0.003mm, radial clearance disabilities 0.002mm; trial and difficult research and development tools, fine grinding bearing taper hole positioning surface, , To protect the knife and the bearing centering cone hole parallel area of more than 85%; change the disc spring.
③ proper scheduling processing technology to prevent the sharp changes in the rate of resection;
② at any time to review the three-dimensional thrust ball bearings tapered hole, the clean and cooperation of the situation, review the atmosphere of the task can be deformed boring device;
① adding compressed air fine filter and dry installation, the filter to the current drainage, demand cleaning or replacement filter;
(3) improvement measures:
Solve the problem. In the event of bearing movement, electrical operating ground faults can cause minor burns
Rust and erosion: contact with water can lead to three-dimensional thrust ball bearing parts corrosion and rust. Test processing, bearing temperature rise and noise deformities, processing precision satisfaction with the processing requirements, troubleshooting. ④ is strictly prohibited overloading operation, there should be timely repair problems, not sick to run. Replace the bearing with the bearing housing, check the radial flutter with a dial gauge, the proximal end is less than 0.006mm, and the distal end is less than 0.010mm at 150mm. Bearing the rare reason for the protection of integrated and echo can be extended bearing life number of preventive measures.
