Cause analysis and measures of bearing throwing of shot blasting machine of shot blasting machine
1. The cause of the failure:
In the production process, the faults of the blasting head bearings of the shot blasting machine mainly include: irregular installation, lack of lubricating oil, fatigue wear, and external force damage.
2. Measures taken:
Corresponding measures: Install in strict accordance with the specifications and regularly overhaul the bearings, add lubricating oil, and improve the lubrication conditions. In the original shot blasting machine, the high-pressure gun is used to lubricate the bearing body of the blasting head. It takes 3 hours to fill the lubricant with 8 blasting heads, which is unsafe and wastes time. At present, the blasting head bearing part of each blasting machine is connected by a high-pressure steel wire hose to be automatically refueled by a high-pressure oil pump. It takes only 10 minutes to fill the lubricant with 8 blasting heads, which is safe and efficient. The proper choice of lubricating oil will directly affect the service life and good mechanical properties of the shot blasting machine. Generally, the surface temperature of the bearing of the blasting head is not easy to exceed 60 °. The innovative sulfopolymer grease 1615EN is used. ; Corrosion resistance; High temperature resistance (100 ° higher than ordinary lithium base grease), long service life characteristics. A high-efficiency axial fan is used for forced heat dissipation to reduce the ambient temperature of the bearing; the venting body is added with a vent hole for automatic lubrication. Regularly repair the impeller, blades, guard plate and belt of the shot blasting machine to eliminate the mechanical resonance caused by external force.
