Abstract
The invention relates to a motor, in particular to a walking motor used for a continuous miner, and the walking motor solves the problem that an existing continuous miner cannot satisfy production requirements because of the adoption of hydraulic drive. The walking motor used for the continuous miner comprises a shell body, a rotating shaft, bearings fixed at two ends of the rotating shaft, a stator and a rotor. The walking motor is characterized in that a driving end of the rotating shaft is fixedly provided with a cylindrical roller bearing and a non-drive end of the rotating shaft is fixedly provided with a deep groove ball bearing. A water jacket is disposed between the shell body and the stator. The motor uses an alternating current transmission control mode, and is convenient to maintain, simple in structure, low in failure rate, and high in overload capacity. The walking motor can be widely applied to coal mining.
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 the coal production technical equipment is mechanization, part mechanization and handwork and the multilayered structure of depositing.Along with coal industry is adjusted industrial structure, integrate energetically, transform existing colliery, close little colliery, eliminate the mode of production that falls behind, accelerate the construction of Large-scale Coal base and modernized large coal mine, this development for China mining machinery enterprise provides good opportunity, and modernized fully-mechanized mining equipment, comprehensive pick equipment and Large Efficient are shelled, adopt, transport, propped up a complete set of equipments in the open and will use in a large number in big-and-middle-sized colliery.Simultaneously, each large-scale mine of China all with longwall system as main mining type, debalance of preparation and winning work has seriously fettered the further performance of production capacity; And a large amount of mine corner coals, residual coal, and be ransacked of in a large number the coal resources that the formula exploitation destroys and compel to be recycled; Some social concerns of Development of Resource-based Cities have been facilitated in the exhaustion of part mine resource, and these all need to promote the application technology of continuous miner and corollary equipment thereof, to ensure the coal industry balanced growth.At present China does not also have complete continuous miner and the corollary equipment thereof can be for reality, the continuous miner running part all adopts hydraulicdriven control mode, the Hydraulic Power Transmission System complex structure, difficult in maintenance, failure rate is high, the overload capacity wretched insufficiency, and requires very high to surface condition under the coal mine; But domestic colliery conditions down-hole is extremely complicated, so hydraulic transmission mode is difficult to meet the demands.Because facing frequent starting and stopping in the continuous miner work, the working condition of frequent forward and backward and frequent overload has motor now owing to the reasons such as unreasonable structure, poor insulativity also can't meet the demands.
Summary of the invention
The present invention provides a kind of movable motor for continuous miner in order to solve existing continuous miner because adopting hydraulic drive can't satisfy the problem of production requirement.
The present invention adopts following technical scheme to realize: be used for the movable motor of continuous miner, comprise housing, rotating shaft, be fixed in bearing, stator and the rotor at rotating shaft two ends; 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 the stator water jacket is installed.The present invention adopts cylinder roller bearing and non-transmision end adopts deep groove ball bearing at the driving end of rotating shaft, in order to bear the impact that Fraquent start and forward and backward cause bearing in the coal-winning machine work, to avoid bearing fault; And adopt the water jacket between housing and stator that motor is carried out water-cooled.Described water jacket is the technology that those skilled in the art realize easily, and can adopt the patent No. is water sleeve for water cooling motor among the ZL200820106251.8.
Further, described stator comprises with the stator core of several wire casings and the stator coil winding that is formed by the multiturn coil coiling; The 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 the wire casing, be placed with successively from the inside to the outside 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, the wedge in the slot liner; The coil of described stator coil winding is comprised of the deposited wire of FCR019 film, CR band glue sealing strip, mica tape and alkali-free glass silk ribbon from inside to outside successively, is lined with 220 polyimides book films between coil turn.For the problem that the turn-to-turn insulation fault very easily occurs under the domestic more abominable condition of power supply, pad 220 polyimides book films between coil turn, can to turn-to-turn insulation again row strengthen; Good electric property, CR band, mica tape and alkali-free glass silk ribbon that heat-sinking capability is strong have been adopted in the deposited wire outsourcing of the FCR019 film of coil, can improve the heat-sinking capability of coil; Slot liner is set in the wire casing of stator core can avoid coil to embed the damage that may occur in the wire casing; With filler strip the stator coil winding is separated, both can adjust the interior space of wire casing and make the stator coil winding loosening in wire casing, can play preferably insulation property again; Thereby make the AC Drive continuous miner have higher dependability and longer life-span, the advantage of performance AC Drive.
Motor of the present invention adopts the A/C transmission control mode, easy to maintenance, simple in structure, failure rate is low, overload capacity is strong, insulating properties is high, solve existing continuous miner because adopting hydraulic drive can't satisfy the problem of production requirement, can be widely used in coal mining.
