Abstract
The utility model relates to a tension pulley widely applied in a scraper plate slag conveyor and other scraper plate conveying devices, especially relates to a sprocket type tension pulley of precision forging, comprising a sprocket. The sprocket is positioned by a positioning pin and is fixed to a tension sprocket wheel shaft sleeve. The utility model is advantageous in that the sprocket adopts alloy steel and is hardened after molding of precision forging, and the sprocket is welded to the tension sprocket wheel shaft sleeve; the bearing capacity is high, the sprocket precision is high, and the transmission is stable with abrasion resistance, long service lifetime and fixed and reliable property; the inherent defect of the forging sprocket is eliminated, the running is stable without impact force or alternating stress, and the defect that the noise is large when a fork type scraper plate passes through the sprocket wheel can be deleted.
Description
Technical field
The utility model relates to a kind of tension wheel that is widely used in submerged slag conveyor and other scraper plate load transfer devices, particularly a kind of finish forge desmodont tension wheel.
Background technology
Existing tension wheel is generally finish forge groove type tension wheel, casting desmodont tension wheel.Wherein finish forge groove type tension wheel began to use in recent years, it is the at present domestic a kind of tension wheel that the most generally uses, the tension wheel wheel body adopts split hot charging formula structure, wheel body adopts cast steel, with chain, the wheel rim of scraper plate contact adopts wear-resistant steel, wheel rim forms through finish forge, has the working accuracy height, wear-resistant, the advantage of long service life, but owing to be groove type mechanism, hinge fork class scraper plate impacts and reverse stress steadily not having when not being with toothed chain wheel, the load maximum that tension wheel is subjected to when crossing hinge fork class scraper plate, normal condition is got back in the load that tension wheel is subjected to after the scraper plate again, and the load that dragveyer tension wheel in service is subjected to is in continuous variation, scraper plate, chain, the tension wheel quick abrasion, reduced scraper plate, chain, tension wheel service life, and scraper plate when crossing tension wheel load increase scraper plate, the tension wheel sound is big.Several years ago widely used casting desmodont tension wheel, tension wheel is integral casting forming cylinder iron, and for ease of the dismounting maintenance of sprocket wheel, the sprocket wheel integral cutting is divided into two or three and uses by the original position assembling of former sprocket wheel.The casting tension wheel exists tissues such as shrinkage porosite, pore, sand holes really to fall into and the hidden danger that has a strong impact on safety in operation such as easy broken, easy to wear.
Summary of the invention
The utility model has overcome above technical matters, provides a kind of hinge fork class scraper plate steadily not have by tension wheel the time and has impacted and reverse stress, and can eradicating hinge fork class scraper plate, to cross the sprocket wheel sound big, intensity height, anti abrasive finish forge desmodont tension wheel.
The utility model is achieved through the following technical solutions:
A kind of finish forge desmodont tension wheel comprises sprocket, and it is characterized in that: described sprocket is located by alignment pin, is fixedly connected on chain tensioner spindle and puts.
The more excellent technical scheme of the utility model is: described sprocket forges and forms, and sprocket is connected with the chain tensioner spindle cover by welding.
The beneficial effects of the utility model are: sprocket use alloy steel material through the finish forge moulding after cure process, sprocket is welded on chain tensioner spindle and puts.Have load-carrying capacity height, the high stable drive of flute profile precision, wear-resistant, the life-span is high, fixing advantage such as reliable, has eliminated the intrinsic defective of cast sprocket, steady nothing in service is impacted and reverse stress, can eradicate hinge fork class scraper plate and cross the big defective of sprocket wheel sound.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1 sprocket, 2 alignment pin, 3 idler sprocket axle sleeves.
Specific embodiment
Fig. 1 is a kind of specific embodiment of the present utility model, and as shown in the figure, in this finish forge desmodont tension wheel, sprocket 1 separates manufacturing with idler sprocket axle sleeve 3, and sprocket 1 is fixed by welding on the idler sprocket axle sleeve 3, and positions by alignment pin 2.Sprocket 1 uses alloy material finish forge moulding after cure to handle, has high bearing capacity, the high stable drive of flute profile precision, wear-resistant, the life-span height, fixing reliable, this molding mode, have a strong impact on the hidden danger of safety in operation from eliminated in essence that tissues such as the intrinsic shrinkage porosite of casting mode, pore, sand holes really fall into and easily broken, easy to wear etc., the connection mode of welding is reliable and stable, and by alignment pin 2 accurate positionings, do not have when making this finish forge desmodont tension wheel operation and impact and reverse stress, can eradicate hinge fork class scraper plate and cross the big defective of sprocket wheel sound.
In sum, the utility model finish forge desmodont tension wheel has been eliminated the intrinsic defective of cast sprocket, does not steadily have during operation and impacts and reverse stress, has fundamentally eliminated hinge fork class scraper plate and has crossed the big defective of sprocket wheel sound; Have load-carrying capacity height, the high stable drive of flute profile precision, wear-resistant, the life-span is high, fixing advantage such as reliable.
