The company mainly produces the following products: 1, scraper machine and accessories: 40T scraper, 30T scraper, small 40T scraper, single chain scraper, heavy duty scraper, mine scraper, scraper conveyor, serrated ring, high-intensity ring chain, chain, link chain, cotter pins, scraper, central trough, sprockets, tail shaft, gear, arc scattered gears, four-, and oblique gears, spur gears, cabinet, rack body, cover plates, separators, head frame, tail rack, central trough, excessive ducts, reducer series, gears, sprockets series, roller series of round series and other accessories. SGD420/22 type scraper drive unit is equipped with 22 motors power plant, transmission power scraper unit is part of the core of the scraper, the main components of the drive unit are as follows: Drives: Drives mainly consists of motor, reducer, sprockets, head frame, tongue plate, blind shafts, chain tensioner and other components, coupling cover the motor, reducer together into a whole, through the power transmitted to the gearbox sprocket, sprocket Promise driven scraper constitute a closed transmission chain, and thus play a role in transporting coal. 1 Reducer: Reducer is three tapered cylindrical gear transmission, power 40kw, transmission ratio 24.564. In order to ensure the normal operation of the bearing, the bearing axial clearance respond appropriately adjusted: the first axis is 0.04 - 0.1; second axis is 0.08-0.15; third axis is 0.07-0.15; fourth axis is 0.2-0.4, arc bevel gear axial position should also be properly adjusted to ensure a reasonable meshing backlash and contact pattern, it engages the backlash of not less than 0.17mm, the tooth contact pattern along the length and direction of tooth height of not less than 50%. The first shaft axial clearance can be adjusted by adjusting the nut, and the second, three, four axial clearance to be adjusted by adjusting the pad. 2 Chain: Chain composed of one half of the drum for the scraper chain transfer power. 3 head frame: head frame from the side panels, welded chassis and other parts group, respectively, to secure the gear unit on its side and blind shaft assembly, the end of the transition groove connection. 4 Blind Shaft: Blind shaft from the bearing seat, blind shafts and other parts, and its main role is to support the sprocket. 5 Chain Adjuster: chain tensioner by the eccentric wheel, shell, brake band, brake wheels and other parts, brake wheel through the brake band to hold fast to the braking, and with the tight chain linked with the use of a tensioner scraping plate chain effect. 6. Transition slots: slot from the tank to help the transition of steel and welded plate group, is the head frame and the central groove of the transition connecting device. How to install the drive unit? Installing Drives: over the head frame with beams connected at the installation site, the nose between the frame and the trough conveyor unloading should maintain a certain height. Reducer installed in the head frame will depend on the mining side of space, you must make the fourth axis reducer seal housing neck and head frame support hole fit, side keyway and feather key head frame side anastomosis, Note breathable upper plug should reducer. Installation and connection cover and in turn, the motor. In the fourth axis reducer output sprocket mounting head and the other end in the nose sprocket mounted blind shaft, drive unit must be level, not tilted. Installed, reducer injection GB/T5903 industrial enclosed gear oil, in order to ensure lubrication, injected a large amount of submerged arc bevel gear shaft 1/3 may not have the seal leakage. If conditions permit, the drive unit can be transported to a whole underground installation site.
