The specific embodiment
The utility model provides a kind of sprocket wheel for scrapper conveyor, and this sprocket wheel is Split chain wheel, when sprocket wheel serious wear, only need to change a part of structure of sprocket wheel, do not need sprocket wheel entirety to dismantle and change, not only reduce and change difficulty, and more save replacing time and cost.
Fig. 1 is the structural representation of a kind of sprocket wheel for scrapper conveyor of providing of the utility model, and Fig. 2 is the structural representation of pair of sprocket.
As shown in Figure 1, the described sprocket wheel for scrapper conveyor comprises chain pulley seat 2 and the gear teeth 1 two parts, wherein two parts are split-type structural, be that the gear teeth 1 can disassemble from chain pulley seat 2, generally, the gear teeth 1 wear and tear relatively more serious and replacement frequency is higher, while changing the gear teeth 1, do not need to change a whole set of sprocket wheel, only the gear teeth 1 need to be disassembled from chain pulley seat 2, simple to operate and convenient and swift.
As shown in Figure 2, pair of sprocket is arranged on same axle drive shaft, and in relative position, sprocket wheel drives the chain being located thereon to move.
Fig. 3 is the structural representation of the chain pulley seat of the sprocket wheel for scrapper conveyor that provides of the utility model, and Fig. 4 is the section-drawing of Fig. 3.
Concrete, as shown in Figure 3 and Figure 4, described chain pulley seat 2 is comprised of circular sleeve structure, and this circular sleeve structure has an axis hole, and this axis hole is used for connecting axle drive shaft.Generally, this chain pulley seat 2 can be set to have two circular sleeve structures, described two circular sleeves all have the axis hole of same diameter size, and the external profile diameter of these two circular sleeves is not identical simultaneously, and these two circular sleeves are the structure that docking is cast into one.
It should be noted that, on the circular sleeve of two different-diameters, can increase another circular sleeve structure that a different-diameter is set, like this, can increase the area of contact of the gear teeth 1 and chain pulley seat 2, reduce to relatively move between chain pulley seat 2 and the described gear teeth 1, thereby prevent because the friction between chain pulley seat 2 and the gear teeth 1 produces the inter deterioration of sprocket wheel.Further, described chain pulley seat 2 can be set to the concentric circular sleeve of multiple different-diameters, the plurality of circular sleeve is as a whole according to being mutually socketed from big to small or from small to large of diameter, and be cast into integrative-structure by foundry technique, thereby form stair-stepping chain pulley seat 2.
It should be noted that, axis hole on described chain pulley seat 2 is used for connecting axle drive shaft, by drive shaft turns, drive described chain pulley seat 2 to rotate, for this chain pulley seat 2 is fixedly connected with described axle drive shaft, on described chain pulley seat 2, keyhole 4 is set, the key that described axle drive shaft is placed can coordinate with described keyhole 4, and axle drive shaft can be connected and fixed with sprocket wheel.
Fig. 5 is the structural representation of the utility model for the gear teeth of the sprocket wheel of scrapper conveyor, and Fig. 6 is the section-drawing of Fig. 5.
As shown in Figure 5 and Figure 6, the described gear teeth 1 are arranged on chain pulley seat 2, by the rotation of chain pulley seat 2, drive the chain on it to rotate.On the described gear teeth 1, there is a wheel hole 6, and at the outward flange in wheel hole 6, multiple teeth 5 are set.Described outward flange of taking turns the structure in hole 6 and the circular sleeve structure of described chain pulley seat 2 matches, that is, the outward flange of described chain pulley seat 2 just can insert cover and be connected to described wheel in hole 6, and both closely cooperate.
It should be noted that, after described chain pulley seat 2 is socketed in the wheel hole 6 of the described gear teeth 1, adopt attaching parts that described chain pulley seat 2 is connected and is fixed with the gear teeth 1.Generally, described attaching parts is bolt, particularly, described chain pulley seat 2 has on the circular sleeve of maximum gauge and is provided with bolt hole 3, this bolt hole 3 is to be generally circumferential arrangement centered by the center of circle of circular sleeve, the concrete arrangement mode of this circumferential arrangement can be that regular equal angles distributes, and can be also that fitfull mode is arranged.
Accordingly, after described chain pulley seat 2 is socketed on the described gear teeth 1, with the bolt hole 3 that same diameter is set on the gear teeth 1 of chain pulley seat 2 upper bolt hole 3 opposite positions, adopt coordinating of bolt and bolt hole 3, can described chain pulley seat 2 and the described gear teeth 1 be connected and fixed as a whole.
It should be noted that, described bolt can be countersunk-heat bolt, and according to the position of the turnover of this countersunk-heat bolt, the bolt cap of described countersunk-heat bolt can be embedded in described chain pulley seat 2 or in the described gear teeth 1, adopt countersunk-heat bolt can make the surfacing of this sprocket wheel, there will not be lofty structure.Or the nut that bolt of rear end plate is used can be embedded in the counter sink in the described gear teeth 1, or is embedded in the counter sink of described chain pulley seat 2.
Described sprocket wheel is that chain pulley seat 2 and the gear teeth 1 are fixed by socket and form, specifically, described chain pulley seat 2 inserts and is embedded in the wheel hole 6 of the described gear teeth 1, and inserting the chain pulley seat 2 that is socketed on the described gear teeth 1 can be concordant with the described gear teeth 1, forms both sides and be the sprocket wheel of flush configuration.In addition, for other need, also can make described chain pulley seat 2 intert after the gear teeth 1, the side of outstanding and the described gear teeth 1, forms a sprocket wheel with stairstepping structure.
Generally, the described gear teeth 1 are circular integral structure, but convenient in order to make to dismantle these gear teeth 1, the gear teeth 1 can be set to by two semicircular structures, during due to the described gear teeth 1, be bolted on described chain pulley seat 2, in the time of need to dismantling the described gear teeth 1, only need part to pull down to described bolt, the gear teeth of two semicircular structures 1 are moved out, dismantle convenient laborsaving.
Same, the described gear teeth 1 can be set to the circular arc formation of three 120 °, the advantage that these split type gear teeth 1 also have is, when some parts of the gear teeth 1 are damaged, and other parts for damage time, only the part gear teeth 1 of damage need to be dismantled down and changed, without all changing the gear teeth 1, the structure of these gear teeth 1 can be saved replacement cost and time more.
The utility model provides a kind of sprocket wheel for scraper plate, this sprocket wheel is split-type structural, comprise chain pulley seat 2 and the gear teeth 1, on chain pulley seat 2, there is the circular sleeve structure of notch cuttype, on the described gear teeth 1, there are wheel hole 6 structures that match with described notch cuttype structure, and be arranged on the tooth 5 of taking turns hole 6 structural outer rim, and on described chain pulley seat 2 and on the gear teeth 1, bolt hole 3 is all set, by bolt, described chain pulley seat 2 is connected and is fixed with wheel hole 6.The sprocket wheel in the course of the work tooth 5 of sprocket wheel is easy to be damaged, in the situation that tooth 5 damages, the gear teeth of described sprocket wheel 1 can be unloaded, change separately, save replacing time and cost, in addition, these gear teeth 1 can also be set to split-type structural, after wherein a part of gear teeth 1 damage, the gear teeth of broken parts 1 are unloaded, change separately the gear teeth 1 of broken parts, more save replacement cost and time.
The utility model also provides a kind of chain scraper machine, on this chain scraper machine, can adopt above-mentioned Split chain wheel, when the tooth 5 of sprocket wheel is damaged, the gear teeth of damage 1 part can be unloaded and changes, save the time of chain scraper machine maintain and replace in the situation that sprocket wheel damages, and save the maintenance cost of sprocket wheel.
