Abstract
The utility model relates to a centre drive type spiral classifier, which changes the peripheral drive of an external gear pair of the original spiral classifier into the centre drive of an axis at the same level, and replaces a cylindrical gear speed reducer with a planet-gear speed reducer or a cycloidal-pin gear speed reducer, wherein the speed reducer directly drives a spiral spindle to rotate through a coupler. The utility model has the advantages of simple structure, high drive efficiency, excellent lubrication and low noise.
Description
Technical field
The utility model relates to a kind of preparation equipment, and this equipment is specially adapted to the hydraulic classiciation of wet grinding product.
Background technology
Existing mining spiral classifier, its spindle drive mode is all the peripheral transmission of open gear pair.It is by motor, cylindrical gear reducer, and pinion, gear wheel, screw spindle and hoisting mechanism are formed, and promptly driving force is delivered on the pinion by reductor, drives the gear wheel that is fixed on the screw spindle again, makes the screw spindle rotary work.The shortcoming of this kind of drive is that structure is huge, Heavy Weight, and the poor lubrication of exposed gear.
Summary of the invention
The purpose of this utility model is that the kind of drive of above-mentioned spiral classifier is improved, and the weight of the transmission device of spiral classifier is lowered, and structure is simpler, and volume is littler.
The technical solution of the utility model is: replace cylindrical gear reducer with planet-gear speed reducer, reductor by shaft coupling directly and screw spindle link, save large and small gear, like this transmission of open gear pair periphery has been changed into the center transmission of horizontal axis, improved transmission efficiency; Replace cylindrical gear reducer with cycloidal planetary gear speed reducer same effect is also arranged.
Reductor of the present utility model adopts planet-gear speed reducer or cycloidal planetary gear speed reducer; The center line of reductor and screw spindle center are at same horizontal axis; Motor-driven planet-gear speed reducer or cycloidal planetary gear speed reducer running, reductor directly drives screw spindle work by shaft coupling.
The utility model replaced the peripheral kind of drive of cylindrical gear reducer and a pair of open gear pair, and it is high that transmission efficiency is got owing to adopt planet-gear speed reducer or the cycloid pin reductor and the center kind of drive, and lubricated good.As everyone knows, it is special that planet-gear speed reducer and cycloidal planetary gear speed reducer have that compact conformation, volume and quality are little, gear range is big, efficient is high, noise is low etc., therefore this mode will be structurally more compacter than old-fashioned spiral classifier, and weight is lighter, and noise is also lower.
