Pulleys are important components for belt conveyors.In order to meet the requirements of long-distance high-speed large-capacity belt conveyor, LIBO adopts advanced finite element method, good-quality material, optimized technical process and large high-precision machines to produce good-quality and long-life pulleys.
Driving pulley bearing , by shaft, solar panels, barrel, surface covered by increasing with rubber belt drive roller bearing, friction coefficient between inside pack self-aligning roller bearings, guarantee the stability of support and guarantee the flexible rotation.
Technical feature
1.Middle and heavy pulleys will be inspected with static analysis and Three-dimension finite element analysis software, which strictly ensure the quality;
2.the material for shell is 16Mn of more superior performance instead of Q235, which ensures shell quality and performance, whose content of S and P ensures welding quality;
3.the material for shaft is forged shaft of 40Cr instead of #45 round steel, which improves mechanical property;
4.the bearing block and taper-lock are ground, which ensure the installation precision;
5.the welding line and shaft are inspected by NDT and the shaft will be tested three times, which can ensure the quality of shaft and welding line;
6.stress annealing will be done after welding with CO2 gas shielded arc-welding machine, which can ensure the quality of welding line;
7.the contact-sealing is adopted, which enjoys more superior dustproof and waterproof;
8.We design and manufacture pulleys according to DIN, JIS, CEMA and ISO standards.
