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. 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 *6Mn of more superior
performance instead of Q**5, which ensures shell quality and
performance, whose content of S and P ensures welding
quality; 3、the material for shaft is forged shaft of *0Cr
instead of #*5 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.
