Description
Technical Field
The utility model relates to a vertical scraper centrifuge of unloading's among coal dewatering process research and development and the technical field of manufacturing of coal washery specifically are vertical scraper centrifuge's of unloading belt straining device.
Background
At present, the vertical scraper discharge centrifuge of coal washery no-gear differential type uses two groups of belts to transmit the rotational speed alone, consequently comes the mode of tensioning belt through the adjusting motor position and can't satisfy actual need, needs to increase straining device and comes the tensioning second group belt, and current straining device structure is complicated, and the preparation is difficult, and is with high costs, and the fault rate is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem to provide a simple structure, processing low cost, the vertical scraper of being difficult for breaking down centrifuge's belt straining device of unloading.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides a belt straining device of vertical scraper discharge centrifuge, includes the centrifuge organism, still includes roller bearing, pedestal, fixing base, and the both ends of roller bearing are installed on the pedestal through self-aligning bearing, fixing bolt respectively, and equal threaded connection has adjusting nut and lock nut on the upper end pole of pedestal and the lower end pole, is provided with the fixing base that is used for spacing adjusting nut on the centrifuge organism respectively, and the adjusting nut suit is in the fixing base that corresponds.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
through rotating the adjusting nut, the purpose of tensioning the belt is realized by converting the rotation of the nut into the axial linear reciprocating motion of the shaft bracket through the thread pair, and the tensioning mechanism has the advantages of simple structure, easiness in manufacturing, low processing cost and low failure rate.
Preferably, the present invention further provides:
the adjusting nut is provided with an annular clamping table, and the fixing seat is provided with a clamping groove matched with the annular clamping table.
The shaft bracket is provided with a roller mounting groove, and the roller is mounted in the roller mounting groove through a self-aligning bearing and a fixing bolt.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: a roller 1; a self-aligning bearing 2; a fixing bolt 3; a shaft bracket 4; an adjusting nut 5; a fixed seat 6; and a nut 7 is locked.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1, a belt tensioning mechanism of vertical scraper discharge centrifuge, including the centrifuge organism, still include roller 1, pedestal 4, fixing base 6, install on pedestal 4 through self-aligning bearing 2, fixing bolt 3 respectively at roller 1's both ends, equal threaded connection has adjusting nut 5 and lock nut 7 on pedestal 4's the upper end pole and the lower end pole, is provided with the fixing base 6 that is used for spacing adjusting nut 5 on the centrifuge organism respectively, and adjusting nut 5 suit is in corresponding fixing base 6.
An annular clamping table is arranged on the adjusting nut 5, and a clamping groove matched with the annular clamping table is arranged on the fixing seat 6.
The shaft bracket 4 is provided with a roller mounting groove, and the roller 1 is arranged in the roller mounting groove through the self-aligning bearing 2 and the fixing bolt 3.
The using method comprises the following steps: the two adjusting nuts 5 rotate simultaneously, and the shaft bracket 4 is driven to axially reciprocate through the threads of the inner holes of the adjusting nuts, so that the purpose of adjusting the tightness of the belt is achieved; wherein the roller 1 is driven and is assembled on the shaft bracket 4 through the self-aligning bearing 2 and the fixing bolt 3; when the roller 1 moves to a proper position (namely the tightness degree of the belt is suitable for actual requirements), the locking nut 7 is locked, and the stability of the whole mechanism is ensured; wherein the fixed seat 6 is arranged on the centrifuge body.
The utility model is suitable for a new-type no gear differential centrifuge's belt tensioning through rotating adjusting nut 5 to the screw thread pair rotates the axial straight reciprocating motion who turns into pedestal 4 with the nut and realizes the purpose for the belt tensioning, is applicable to current production and processing technology, and this straining device simple structure easily makes, and the processing cost is low, and the fault rate is low.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
