Sprocket shaft group, it positions mode, sprocket piece and main shaft with location mode many employings bearing block of aircraft tail shelf
It is connected as a single entity by flat key or spline mode, the power of elevating conveyor scraper chain is transferred to through sprocket piece main
Axle, is rotated around bearing block inner ring by main-axis end bearing.
But the transfer conveyor tail sprocket shaft group of this kind of structure, design of spindle bearings distance is excessive, and main shaft passes through axle
Float support is formed between bearing and aircraft tail shelf.When elevating conveyor scraper chain frequent impact sprocket shaft group,
Easily cause the black box between main shaft bearing fatigue damage and sprocket piece and bearing block to damage, leakage of oil occurs
Phenomenon, reduces the sprocket shaft group life-span.
Utility model content
The purpose of this utility model is to provide a kind of short span transfer conveyor tail sprocket shaft group, it is possible to shorten
The main shaft of transfer conveyor tail sprocket shaft group and shaft strength span, the manufacturing procedure of reducible chain opinion axle group,
Improve tail sprocket shaft group installation accuracy, improve the sprocket shaft group life-span.
A kind of short span transfer conveyor tail sprocket shaft group, including aircraft tail shelf, main shaft, pacifies on this main shaft
Equipped with left bearing, left sprocket wheel, spacer, right sprocket wheel and right bearing, it is particular in that: described master
Axle is directly rigidly attached on aircraft tail shelf, is set with left bearing on this main shaft, solid on this left bearing
Surely it is set with left sprocket wheel, and by this left sprocket wheel, gland is installed, between this gland and left bearing
Sealing member is installed；On this main shaft, wherein also it is set with right bearing, fixing suit on this right bearing
There is right sprocket wheel, and by this right sprocket wheel, gland is installed, be provided with between this gland and right bearing
Sealing member；It is fixedly connected into one by spacer between the most above-mentioned left sprocket wheel and above-mentioned right sprocket wheel.
Wherein it is fixedly connected into and integrally refers to that left sprocket wheel, spacer and right chain wheel set are welding as one.
Test proves that, after using the technical solution of the utility model, efficiently solve existing structure and turn
Carrier aircraft tail sprocket shaft group design of spindle bearings distance problems of too, by being directly rigidly attached at machine by main shaft
On tailstock, saving the intermediate link of bearing block float support, entirety improves the sprocket shaft group life-span, effectively
Reduce well work work surface transporting equipment fault rate.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model background technology；
Accompanying drawing 2 is structural representation of the present utility model.
Detailed description of the invention
As in figure 2 it is shown, this utility model provides a kind of short span transfer conveyor tail sprocket shaft group, bag
Include aircraft tail shelf, main shaft 1, this main shaft 1 is provided with left bearing 4a, left sprocket wheel 5a, spacer 6,
Right sprocket wheel 5b, right bearing 4b, the most described main shaft 1 is directly rigidly attached at the tail of elevating conveyor
On frame, being set with left bearing 4a on this main shaft 1, on this left bearing 4a, fixed cover is equipped with left chain
Wheel 5a, and by this left sprocket wheel 5a, gland 2 is installed, between this gland 2 and left bearing 4a
Sealing member 3 is installed；Wherein on this main shaft 1, also it is set with right bearing 4b, at this right bearing 4b
Upper fixed cover is equipped with right sprocket wheel 5b, and is provided with gland 2 by this right sprocket wheel 5b, at this gland 2
And sealing member 3 is installed between right bearing 4b；The most above-mentioned left sprocket wheel 5a and above-mentioned right sprocket wheel 5b it
Between by spacer 6 be fixedly connected into one, specifically by left sprocket wheel 5a, spacer 6 and right sprocket wheel 5b
Assembly welding is integrated.
Specifically two (carrying) bearings are separately mounted in two sprocket body, bearing and sprocket wheel
Positioned by the gland 2 of both sides, and sprocket wheel inwall and bearing outer ring are tight fit.
Embodiment 1:
As in figure 2 it is shown, this utility model is a kind of novel short span transfer conveyor tail sprocket shaft group, bag
Include 1, two glands of a main shaft, 3, two bearings of 2, two sealing members, two sprocket wheels, one every
Set 6.On the basis of this utility model is the most existing conveying equipment, by changing transmission
Principle, the direct rigidity (fixing) of main shaft 1 of sprocket shaft group is arranged on aircraft tail shelf, by two carryings
Bearing is separately mounted in two sprocket body, directly sprocket wheel and main shaft 1 is divided into two bodies, two sprocket wheels
