With the development of belt conveyor towards long distance , high speed , long carring and large driving power , besides driver device , Especially under the condition of starting , running , braking and stopping , And also , as one of the most indispensable parts in belt conveyor , take-up has an direct effect on safety , reliability and sbability of conveyor system on a whole .
By contrasting and analyzing of various take-ups on belt conveyor . This design is mainly about automatic windlass tension station . Its drive part makes up into worm pair and gear driver . Windlass uses worm gear worm driving reel which binds wire rope to pull tight adhesive tape . In the meantime , it adopts the frequency conversion adjusting speed motor to control tensioning force . It adjusts pressing the strength size as necessary according to the different working condition . And the system can work safely and reliably in various conditions . It can be the greatest degree lengthen the leather belt the life , greatly saved the cost .
This paper expands on the strain unit of windlass in theory from the perspect of the whole system . When adhesive tape starts , strain unit can supply enough great tensioning force ; When finishes , it can make tensioning force of leather belt regaining assessed amount to keep normal running of leather belt . characteristic of this design is high reliability , small volume , big tensile force end so on .
