Description
Technical field
The utility model relates to motor, is specially a kind of out frame and adds the two water route cooling of end cap explosion separation motor.
Background technology
Because of technology and cost of winning reason, in the past seldom to the exploitation in girdle ore deposit, along with increase, in the exploitation of progressively carrying out thin seam mining equipment to energy demand.The electronic coal-winning machine power of motor that is used for girdle is required increasing, but constancy of volume, like this, how reducing electric machine temperature rise is a problem.
Summary of the invention
The utility model solves present coal-winning machine power of motor increase, the strict restriction of the volume problem of temperature rise of motor down, provides a kind of out frame to add the two water routes of end cap and cools off explosion separation motor.
The utility model is to adopt following technical scheme to realize: out frame adds the two water route cooling of end cap explosion separation motor, comprise support, the support two ends are fixed with forward and backward end cap respectively (after motor with driving end is, non-transmision end or title dog point are preceding), front and back ends covers through bearings rotating shaft, front and back ends covers and is provided with intercalated water sleeve, also be provided with intercalated water sleeve on the support, intercalated water sleeve on the support communicates with the intercalated water sleeve that front and back ends covers respectively, front end housing is provided with the water inlet of intercalated water sleeve, and rear end cap is provided with the delivery port of intercalated water sleeve.During machine operation, cooling water enters the intercalated water sleeve of front end housing from the water inlet on the front end housing, and the intercalated water sleeve on support flow to the intercalated water sleeve of rear end cap, is flowed out by the delivery port on the rear end cap again.Circulation by cooling water realizes the cooling to support and forward and backward end cap, and then takes the heat of motor internal out of, thereby realizes fully reducing the purpose of electric machine temperature rise.
Further, be fixed with the rotor balancing dish at the rotating shaft two ends, the rotor balancing dish is a ring bodies, and the rotor balancing dish is provided with flabellum, adds air circulation in the speed motor when rotor rotation, makes rotor and motor internal obtain efficient cooling more.So promptly save the motor axial space, reduced the balance difficulty again.
Out frame described in the utility model adds the two water route cooling of end cap explosion separation motor at specific use object---coal coal-winning machine, and partial structurtes are improved.By covering intercalated water sleeve is set at support and front and back ends, improved support and forward and backward end cap heat conductivility, reduce the temperature rise of stator winding and internal rotor; Help motor volume and reduce, weight saving; Also help under the situation that does not increase motor volume and weight, improve the power of motor, guarantee the electromechanics performance.The motor axial space has promptly been saved in the shape of rotor balancing dish and fixed position, has reduced the balance difficulty again, simultaneously by on the rotor balancing dish flabellum being set, has realized rational wind path design, has both reached best relatively cooling effect, has reduced noise again.Satisfied instructions for use, be applicable to that fully the coal coal-winning machine uses as the coal-winning machine motor.The utility model efficiently solves the problem of temperature rise of fire-proof motor, guarantees the performance of motor performance, makes the life-span of motor be greatly improved.The utility model is particularly useful for the coal coal-winning machine.
