Bearing common sense: difference between pitch bearing and yaw bearing

1. Anti-corrosion treatment of pitch bearings and yaw bearing external alignment. In order to meet the anti-corrosion requirements of yaw bearings, we use arc spraying long-term anti-corrosion technology. It uses special arc spraying equipment to melt and atomize corrosion-resistant metal (pure aluminum or zinc). Sprayed to the exterior of the workpiece to form a metal arc spray coating; then it is closed with a highly permeable corrosion-resistant coating; it constitutes a long-lasting anti-corrosion composite coating for arc spraying. Its skill characteristics are: 1 long anti-corrosion life; up to 20 years Above, 2 coatings have high contact force and 3 coatings are of good quality. The process road: semi-finished products for inner and outer rings of bearings → pre-sanitary → workpiece pre-protection → sand blasting → arc spraying → shutdown treatment; 
1) Bearing inner and outer ring semi-product preparation In order to ensure the yaw bearing has a high appearance quality; the anti-corrosion spraying process is organized after all machining; the sprayed bearing parts are directly stored in the warehouse after completion; ensure that the anti-corrosion layer will not be Bruise. 
2) Pre-sanitary organic solvent for degreasing treatment; bearing semi-products may have oil stain on the surface after machining; in order to ensure the quality of spraying, it is necessary to organize the hygienic process before spraying. 
3) Pre-protection of the workpiece Before the blasting and spraying, the special surface pre-welding tool is used to complete the circular arcing of the workpiece, the threaded hole and the appearance without spraying. 
4) Sand blasting roughens the outer and outer rings of the bearing; adds the contact surface between the coating and the workpiece; makes the surface of the workpiece more activated; improves the contact strength of the coating. 
5) Arc spray arc spraying (pure aluminum or zinc) equipment Firstly, it includes DC power supply, spray gun, air compressor and air filter; it mainly controls the arc voltage, current, wire feed speed, compressed air pressure, spray interval and other parameters.
