Description
Technical field
The utility model relates to the machine field that adopts cooling provision, is specially a kind of oil cooling motor.
Background technology
Can produce a large amount of heats during machine operation, must in time be discharged, otherwise temperature rise surpasses the rated value of motor, gently then influences electric machine operation state and useful life, heavy then burn motor and cause accident.The motor cooling generally has air-cooled and the oil cooling dual mode, air-cooled open-type electric machine and the protected machine of being only applicable to, to impervious machine and fireproof machine and be not suitable for, oil cooling is because the thermal capacity of oil is big, can also adopt pump to give forced circulation, thereby cooling effect is better than air-cooled.At present, a kind of oil-immersed type cooling motor, the major defect of the type of cooling of this motor has three: at first blade stirs cold oil and can cause energy loss, the more high loss of rotating speed is more big, secondly cold oil can only cool off stator end basically, poor to stator central part cooling effect, last very fast owing to not having heat exchanger thereby oil liquid temperature to rise, thus radiating effect reduced.A kind of oil injection type cooling motor.It is on the basis of oil-immersed type, installed an oil storage tank additional in the bottom of engine housing, oil pipe one end is connected with jet on the end cap, and the other end is connected with oil storage tank by oil pump, oil storage tank is connected by oil return opening and electric machine casing, is filled with cold oil in oil pipe and the oil storage tank.By oil pump cold oil is transported to the end cap at electric machine casing two ends during use from oil storage tank, spray to from nozzle and to be fixed on epitrochanterian blade, by blade the cold oil stirring is splashed to the motor case inwall and cools off, last cold oil is got back to oil storage tank by oil return opening.Compare the oil-immersed type cooling motor, this mode is because the flow of cold oil is big, and has oil storage tank that cold oil is cooled off, so cooling effect will be got well a lot, but cold oil still will pass through the stirring of blade, so energy loss is also bigger during high speed.Simultaneously, also there are a common defective in oil-immersed type and oil injection type, and generally speaking, the stator of these two kinds of motors and electric machine casing are to adopt interference fit to fix, and install by hot cover process.For the motor of aluminum electric machine casing, because the thermal coefficient of expansion of aluminium is about the twice of stator material therefor iron, so the difficult control of the magnitude of interference.If the magnitude of interference is too small, along with the rising of motor temperature, because the influence of thermal expansion, the magnitude of interference can diminish gradually, even the gap occurs and cause motor stator axially to rotate, can't carry-over moment; If the magnitude of interference is bigger than normal, can cause installing difficulty again, the Stator and electrical machine housing all produces gross distortion after perhaps installing influences motor quality.
Summary of the invention
In order to overcome the defective of prior art, provide a kind of motor of easy for installation, good heat dissipation effect.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of oil cooling motor, comprise electric machine casing, axle, stator, rotor, oil groove, oil pipe, oil pump, oil storage tank, oil return opening, cold oil, the cold oil device, axle is installed in the electric machine casing middle part, stator is fixedly arranged on the electric machine casing inwall, rotor is fixedly arranged on the axle, oil groove is welded in electric machine casing top inwall, oil groove is circumscribed with oil pipe, oil pipe is connected with the cold oil device by oil pump, the cold oil device also is connected with the oil storage tank of electric machine casing below, oil storage tank is connected with electric machine casing by oil return opening, be filled with cold oil in the oil storage tank, described cold oil device comprises the water-cooled treatment system, air-cooled treatment system, cold oil cold treatment system three parts, and water-cooled treatment system, air-cooled treatment system, the cold oil cold treatment system connects successively.
