Wherein, described sectional type bull gear 2 adopts the ADI material, is divided into 6 sections, and each is segmented into 1-2m, and every section side is bolted fixing.
Wherein, open type running part of the present utility model adopts the version of overall base, and all pedestals and crane carriage vehicle frame are whole to be manufactured, and guarantees the accuracy requirement of open type transmission.
Beneficial effect
Major advantage in sectional type bull gear open type transmission hoister winch design of the present utility model and good effect:
(1) two cover miniature gears assemblings are installed in the sectional type bull gear both sides, with the intermeshing transferring power of sectional type bull gear, line and the horizon at both centers are at a certain angle, and structure is monolateral pair of drive form, makes more compact and reasonable of structure.
(2) sectional type bull gear by Bolt Connection the end at reel, brake disc is bolted the other end at reel, the connection mode at two ends is simple in structure, easily processing and manufacturing and replacing.
(3) applied a kind of sectional type bull gear open type transmission hoister winch, the sectional type gear ring adopts the ADI material, is divided into 6 sections, and each segmentation is about 1-2m, it is fixing that every section side is bolted, and has easy casting, operation and change convenient and quality precision and the advantage such as more easily control.
(4) the open type running part adopts overall base, and all pedestals and crane carriage vehicle frame are whole manufactures, and guarantees the accuracy requirement of open type transmission.
