Abstract
The invention relates to a driving device for a machine head of a scraper conveyor for a coal mine. The driving device comprises a chain wheel shaft, wherein a chain wheel is arranged at the middle part of the chain wheel shaft by fit through a spline, transmission gears are sheathed at the two ends of the chain wheel shaft, a bearing and a bearing seat are arranged on the chain wheel shaft on the two sides of the chain wheel, a shaft shoulder sleeve is arranged between an inner ring of the bearing and the spline of the chain wheel shaft, a liner bushing is arranged between an outer ring of the bearing and the bearing seat, a floating sealing device I is arranged between the liner bushing and the chain wheel, and a lubricating cavity is formed among the liner bushing, the chain wheel and the shaft shoulder sleeve; and a gland bush is mounted on the back surface of each transmission gear, a pressing sleeve is arranged in an inner cavity at the outer end of the bearing seat, and a floating sealing device II is arranged between the pressing sleeve and the gland bush. The driving device disclosed by the invention utilizes the gland bush, the liner bushing, the pressing sleeves and the shaft shoulder sleeve to press the floating sealing device I between the liner bushing and the chain wheel and the floating sealing device II between the pressing sleeve and the gland bush for sealing, thereby ensuring a fixed gap between the floating sealing device I and the floating sealing device II and prolonging the service life of the bearing and the chain wheel.
Description
Technical field
The present invention relates to a kind of colliery load transfer device, particularly a kind of colliery scraping transporter head driving device.
Background technology
Drive sprocket is the driver element of slat conveyer key.By the engagement of drive sprocket and chain link, with the rotating torques of driving motor, become the straight line tractive force and pass to scraper chain.Scraper chain is around driving chain crop rotation closed circumference motion, and the raw coal in slat conveyer cochain road is transported to head from tail, realizes the basic function of slat conveyer.Because the location structure of drive sprocket in the past, oiling mode etc. has affected that the location of drive sprocket is unreliable, the sealing of floating seal, filling conduit leakage of oil midway, change the phenomenons such as inconvenient, service life and the replacement cycle of drive sprocket have been reduced, user's strong request improves the sprocket wheel life-span, avoids the down-hole to change sprocket wheel.But so far, the domestic sprocket wheel life-span can not be satisfied the needs of China modernization coal-face exploitation, and drive sprocket becomes and hinders the key factor that domestic heavy type, superduty slat conveyer further develop.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of compact conformation, long service life, changes easily colliery scraping transporter head driving device.
The technical problem to be solved in the present invention is to realize by the following technical programs, a kind of colliery scraping transporter head driving device, comprise sprocket shaft, sprocket wheel is equipped with by spline fitted in the sprocket shaft middle part, two ends at sprocket shaft all are set with transmission gear, sprocket shaft in the sprocket wheel both sides is equipped with bearing and bearing seat, be characterized in: between the spline of the inner ring of bearing and sprocket shaft, be provided with shaft shoulder cover, between the outer ring of bearing and bearing seat, be provided with lining, between lining and sprocket wheel, be provided with the floating seal I, at lining, form lubricating cavity between sprocket wheel and the shaft shoulder cover; The back side at transmission gear is equipped with gland, and inner chamber is provided with gland in the outer end of bearing seat, is provided with the floating seal II between gland and gland.
The technical problem to be solved in the present invention can also be come to realize that further the outside of described transmission gear is fixed with guard shield by the following technical programs.
The technical problem to be solved in the present invention can also come further to realize that the top of described bearing seat and bottom respectively are provided with a positioning groove by the following technical programs, be equipped with in the positioning groove be arranged on the transport plane headstock on the positioning key that cooperates of mounting groove.
Compared with prior art, the present invention utilizes gland, lining, gland and shaft shoulder cover that the floating seal I between lining and the sprocket wheel and the floating seal II between gland and the gland are pushed down sealing, guaranteed the fixed interval (FI) of floating seal I and floating seal II, the service life of having improved bearing and sprocket wheel; Utilization is installed in the positioning key in the bearing seat positioning groove, the location of having guaranteed the sprocket wheel safety and precise.
