Abstract
The utility model relates to a ring sprocket, including central authorities have the shaft hole the annular fluted disc of circle and the sprocket that the fluted disc was fixed mutually, the positioning pin of sprocket through radial installation with the excircle facial features of fluted disc is connected, just the fluted disc welds with the seam crossing of sprocket, the fluted disc includes the curved fluted disc piece of polylith, polylith the fluted disc piece is connected fixedly with wheel hub through the fastener. The utility model discloses ring sprocket hardness, intensity, wear -resisting corrosion resistance improve greatly, and life prolongs greatly, overhaul and to maintain convenient and fast more, the normal operating of having satisfied whole platform scraper blade dragveyer equipment and even a whole set of generating set of bigger degree.
Description
Technical field
This utility model belongs to technical field of mechanical transmission and in particular to a kind of slot ring antenna.
Background technology
Currently, thermal power generation（I.e. combustion of fossil fuel produces heat energy, is then converted to electric energy）It is still China's power source
Major way, the lime-ash that whether fluid bed or coal-powder boiler unit coal combustion produce all has to pass through the cold of slag removing system equipment
But a series of, process such as conveying.
Submerged slag conveyor is the nucleus equipment in coal-powder boiler unit slag removing system, the lime-ash mainly boiler combustion being produced
Carry out efflorescence, cooling, and be delivered to upstream device.Submerged slag conveyor is mainly by chain, scraper plate, drive mechanism, tractor, chain
The parts such as bar clamping system, train, control device form.Tractor is mainly made up of sprocket wheel, wheel hub, power transmission shaft etc.,
Tractor is driven by motor and rotates, and then sprocket wheel drives annular chains to move, and chain and scraper plate are taken hinged, in turn
Scraper plate is driven to move, the conveying moving and then completing lime-ash of scraper plate.In running, tractor sprocket wheel is subject to very big
Moment of torsion, needs the mechanical properties such as very high wearability, hardness, this is accomplished by sprocket wheel reasonable mechanical property ----anti-
Draw, wear-resistant, anticorrosive, hardness high.
But existing concave tooth type slot ring antenna adopts QT700-2 integral casting forming, it is to avoid there is not pore, burning into sand
Etc. casting flaw, and non-hardened process, have that bearing capacity is low, easy tooth-breaking, flute profile low precision, not wear-resisting, the life-span is low, fixing
The defect such as unreliable.Thus result in repair and maintenance frequency high, and be difficult to change maintenance, difficulty is big, far can not meet scraper plate
The safe and stable operation of dragveyer.Tractor sprocket wheel due to nowadays running is cast moulding, is susceptible to broken teeth, sprocket wheel breaks
Split, quick abrasion, replacement frequency are high and are difficult some defects such as maintenance replacing, thus had a strong impact on whole submerged slag conveyor equipment
Operation.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem and provides a kind of submerged slag conveyor that is mainly used in
, easily broken teeth, sprocket wheel fracture, abrasion to solve existing submerged slag conveyor tractor sprocket wheel in concave tooth type slot ring antenna
Hurry up, replacement frequency is high and is difficult some defects such as repair and maintenance, it can greatly meet whole submerged slag conveyor equipment and is
Normal operation to a whole set of generating set.
For achieving the above object, this utility model adopts the following technical scheme that：
A kind of slot ring antenna, has the fluted disc of the annular of axis hole and the sprocket that described fluted disc phase is fixing including central authorities,
Described sprocket is connected with the periphery of described fluted disc by the alignment pin of radially installed, and the seam of described fluted disc and sprocket
Place's welding；Described fluted disc includes the fluted disc piece of polylith arc, and described in polylith, fluted disc piece and wheel hub are connected to a fixed by securing member.
Described sprocket is matrix shape tooth, and two free ends of described matrix shape tooth symmetrically have inclined plane inwardly downward.
The surface annular of described fluted disc is disposed with installing hole, solid for being connected with described wheel hub using described securing member
Fixed.
This utility model concave tooth type slot ring antenna compares old-fashioned sprocket wheel hardness, intensity, abrasion and corrosion resistance greatly improve, and
Profile of tooth precision also greatly improves, and service life greatly prolongs, and repair and maintenance is more convenient, greatly meets whole
Platform submerged slag conveyor equipment or even the normal operation of a whole set of generating set.
Brief description
Fig. 1 illustrates slot ring antenna structural representation of the present utility model；
Fig. 2 is the A-A profile of Fig. 1.
Specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this practicality is new
Type is not limited to listed embodiment.
Referring to shown in Fig. 1-2, a kind of slot ring antenna, there is the fluted disc 2 of the annular of axis hole 7 and described tooth including central authorities
The fixing sprocket 1 of disk phase, described sprocket 1 is connected with the periphery of described fluted disc 2 by the alignment pin 3 of radially installed, and
Described fluted disc 2 forms weld layer 8 with the seam crossing welding of sprocket 1；Described fluted disc 2 includes the fluted disc piece of polylith arc, polylith institute
State fluted disc piece to be connected to a fixed by securing member with wheel hub.
Wherein, described sprocket 1 is matrix shape tooth, and two free ends of described matrix shape tooth symmetrically have inclining inwardly downward
Inclined-plane 6.
Wherein, 2 surface annulars of described fluted disc are disposed with installing hole 5, for making multiple being divided into using described securing member
Multiple parts or the fluted disc of piece（Or sprocket wheel）It is connected to a fixed with described wheel hub.
Implement, described sprocket can adopt 20CrMnTi forging molding, intensity hardness is high, profile accuracy is high；Fluted disc
Using 35 steel forging moldings；Sprocket is connected with alignment pin in advance with both fluted discs, is then welded as a whole, the material of alignment pin
Expect for 45 steel.After sprocket tooth form, bulk heat treatmet, afterwards on request by fluted disc at multiple points of lobes 4 cutting sheets, thus being formed
Sprocket wheel is divided into multiple partition members, i.e. limb or lobe body, is illustrated in figure 14 at 3 points of lobes, forms 3 cut piece.
In this utility model, described slot ring antenna and wheel hub are connected as one using high-intensity fasteners.
The feature of this Novel chain wheel split-type, can meet and need not dismantle the parts such as motor, shaft coupling, can meet
" online " burst is changed, convenient and swift.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
