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 scraper conveyor for coal mine head driving device.
Background technology
Drive sprocket is the driver element of slat conveyer key.By engaging of drive sprocket and chain link, by the rotating torques of driving motor, become straight line tractive force and pass to scraper chain.The raw coal in slat conveyer cochain road, around the motion of driving chain crop rotation closed circumference, is transported to head from tail, realizes the basic function of slat conveyer by scraper chain.Due to the location structure of drive sprocket in the past, oiling mode etc. have impact on that the location of drive sprocket is unreliable, the sealing of floating seal, filling conduit midway leakage of oil, change the phenomenons such as inconvenient, reduce service life and the replacement cycle of drive sprocket, user is strongly required to improve the sprocket wheel life-span, avoids down-hole to change sprocket wheel.But so far, the domestic sprocket wheel life-span can not meet the needs that China's modernization coal-face is exploited, the key factor that drive sprocket becomes the domestic heavy type of obstruction, superduty slat conveyer further develops.
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 scraper conveyor for coal mine head driving device easily.
The technical problem to be solved in the present invention is realize by the following technical programs, a kind of scraper conveyor for coal mine head driving device, comprise sprocket shaft, by spline fitted, sprocket wheel is housed in the middle part of sprocket shaft, all transmission gear is set with at the two ends of sprocket shaft, the sprocket shaft of sprocket wheel both sides is equipped with bearing and bearing seat, be characterized in: between the inner ring and the spline of sprocket shaft of bearing, be provided with shaft shoulder cover, lining is provided with between the outer ring and bearing seat of bearing, floating seal I is provided with between lining and sprocket wheel, at lining, lubricating cavity is formed between sprocket wheel and shaft shoulder cover, at the back side of transmission gear, gland is installed, is provided with gland at the outer end inner chamber of bearing seat, between gland and gland, is provided with floating seal II.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, and the outside of described transmission gear is fixed with guard shield.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, and the top of described bearing seat and bottom are respectively provided with a positioning groove, is provided with the positioning key coordinated with the mounting groove be arranged on transport plane headstock in positioning groove.
Compared with prior art, the present invention utilizes gland, lining, gland and shaft shoulder cover that the floating seal I between lining and sprocket wheel and the floating seal between gland and gland II are pushed down sealing, ensure that the fixed interval (FI) of floating seal I and floating seal II, improve the service life of bearing and sprocket wheel; Utilize the positioning key be arranged in bearing seat positioning groove, ensure that the location of sprocket wheel safety and precise.
