Product Description

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 consists of bearing , shaft, solar panels and barrel, surface covered with rubber belt drive roller bearing, increasing friction coefficient between inside pack self-aligning roller bearings, guaranteeing 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 *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.
