Roller,Its material is 45 and Q235,for the Bucket Conveyor System:
Chain bucket conveyor roller adopts wear-resisting material, material hardness value is HRC ≧ 40, equipment running 7500 hours safely;
The reasons of wheel loose, fall off, climb rail:
1. The design and installation is unreasonable, so the clearance between wheel and rail is bigger
2. The rail wear serious, increase the gap between roller
3. The wheel rim wear calendar harm, don’t changed in timeHole
4. Roller stents stiffness is insufficient, and the matching of the rolling shaft is clearance fit, running after a period of time, stent hole grinding, roller and race bucket partial derailment,
5. Bucket chain stiffness is insufficient, run after a period of time, the roller chain bucket bottom concave down, the roller is not the same level.
The solution:
1. Lessen the narrow gauge, the clearance between the wheel and rail to unilateral 1.5 mm;
2. Replace the orbit, shorten gauge, reduce runtime about channeling momentum wheel;
3. Replace worn wheel rim in time, increase the height and thickness of the wheel rim;
4. Improve the wheel bracket stiffness will be made of flat steel roller bracket instead of square steel roller socket, improve the service time of the belt roller coal tub;
5. Appropriate increase the pin diameter, increase the hardness, increasing the thickness of the chain plate;
6. Track and wheel contact tail wheel tensioning device working, regulation tail wheel tensioning device;
