Description
Technical field
The present invention relates to motor, be specially a kind of movable motor for continuous miner.
Background technology
At present, coal in China production technique outfit of equipment level is lower, and coal production technical equipment is mechanization, some mechanical and handwork the multilayered structure of depositing.Along with coal industry adjusts industrial structure, integrate energetically, transform existing colliery, close small coal mines, eliminate the mode of production fallen behind, accelerate the construction of Large-scale Coal base and modernization large coal mine, this provides good opportunity for development of mining machinery enterprise of China, modernization fully-mechanized mining equipment, combine pick equipment and the outdoor stripping of Large Efficient, adopt, transport, a complete set of equipments will use in a large number in big-and-middle-sized colliery.Meanwhile, each large-scale mine of China is all using longwall system as main mining type, and debalance of preparation and winning work has seriously fettered the further performance of production capacity; And a large amount of mine corner coal, residual coal, and the coal resources being ransacked of formula exploitation destruction are in a large number compeled to be recycled; The exhaustion of part mine resource facilitates some social concerns of Development of Resource-based Cities, and these all need the application technology promoting continuous miner and corollary equipment thereof, to ensure coal industry balanced growth.Current China does not also have complete continuous miner and corollary equipment thereof can for actual, continuous miner running part all adopts hydraulicdriven control mode, Hydraulic Power Transmission System complex structure, difficult in maintenance, failure rate is high, overload capacity wretched insufficiency, and require very high to underground coal mine surface condition; But domestic underground coal mine condition is extremely complicated, so hydraulic transmission mode is difficult to meet the demands.Because facing frequent starting and stopping in continuous miner work, the working condition of frequent forward and backward and frequent overload, existing motor also cannot meet the demands due to the reason such as unreasonable structure, poor insulativity.
Summary of the invention
The present invention, in order to solve existing continuous miner because of the problem adopting hydraulic drive cannot meet production requirement, provides a kind of movable motor for continuous miner.
The present invention adopts following technical scheme to realize: for the movable motor of continuous miner, comprise housing, rotating shaft, the bearing being fixed on rotating shaft two ends, stator and rotor; The driving end of described rotating shaft is fixed with cylinder roller bearing and non-transmision end is fixed with deep groove ball bearing; Between described housing and stator, water jacket is installed.The present invention adopts cylinder roller bearing and non-transmision end to adopt deep groove ball bearing, in order to bear the impact that in coal-winning machine work, Fraquent start and forward and backward cause bearing, to avoid bearing fault at the driving end of rotating shaft; And adopt the water jacket between housing and stator to carry out water-cooled to motor.Described water jacket is the technology that those skilled in the art easily realize, and the patent No. can be adopted to be water sleeve for water cooling motor in ZL200820106251.8.
Further, described stator comprises the stator core with several wire casings and the stator coil winding by multiturn coil coiling; Stator coil winding is divided into upper strata sets of stator coils and lower floor's sets of stator coils; Be provided with the slot liner of coincideing with its grooved shape in wire casing, in slot liner, be placed with filler strip and slot wedge under bottom land filler strip, lower floor's sets of stator coils, interlayer filler strip, upper strata sets of stator coils, wedge from the inside to the outside successively; The coil of described stator coil winding is with glue sealing strip, mica tape and alkali-free glass silk ribbon to form by FCR019 film deposition wire, CR from inside to outside successively, is lined with 220 polyimides book films between coil turn.For the problem that turn-to-turn insulation fault very easily occurs under domestic more severe condition of power supply, between coil turn, pad 220 polyimides book films, can to turn-to-turn insulation row reinforcement again; The FCR019 film deposition wire outsourcing of coil have employed good electric property, CR band, mica tape and alkali-free glass silk ribbon that heat-sinking capability is strong, can improve the heat-sinking capability of coil; Arranging slot liner in the wire casing of stator core can avoid coil to embed the damage that may occur in wire casing; With filler strip, stator coil winding is separated, both can adjust space in wire casing and stator coil winding is not loosened in wire casing, good insulation property can have been played again; Thus make AC Drive continuous miner have higher dependability and longer life-span, play the advantage of AC Drive.
Motor of the present invention adopts A/C transmission control mode, easy to maintenance, structure is simple, failure rate is low, overload capacity are strong, insulating properties is high, solve existing continuous miner because of the problem adopting hydraulic drive cannot meet production requirement, can coal mining be widely used in.
