Description
Technical field:
The utility model relates to electric field, particularly relates to motor, particularly has the motor of cooling structure, specifically a kind of novel oil-immersed type oil-cooled motor.
Background technology:
The machine operation time has been grown and can produce a large amount of heats, must take away heat in time, otherwise temperature exceedes motor copper cash thermal endurance class, gently then affects electric efficiency and useful life, heavy then motor damage causes accident.In prior art, oil-cooled motor mainly contains two kinds of modes and dispels the heat, a kind of oil-immersed type cooling motor, the type of cooling of this motor mainly contains three kinds of defects: stir cold oil when first rotor rotates and can cause the loss of motor power and the reduction of efficiency, especially during high rotating speed, loss is larger, secondly cold oil can only cool armature ends substantially, poor to armature central part cooling effect, the heat radiation of last this mode does not have heat-exchange system, and oil temperature together can rise too fast with motor, significantly reduces the integral heat sink effect of motor like this, another kind is oil injection type cooling motor, it is on the basis of oil-immersed type, an oil storage tank has been installed additional in the bottom of engine housing, oil pipe one end is connected with the jet on end cap, the other end is connected with oil storage tank by oil pump, oil storage tank is connected with electric machine casing by oil return opening, cold oil is filled with in oil pipe and oil storage tank, by oil pump, cold oil is transported to from oil storage tank the end cap at electric machine casing two ends during use, spray to from nozzle and be fixed on epitrochanterian blade, by blade, cold oil stirring is splashed in motor internal cavity, oil storage tank is got back to by oil return opening by the last cold oil of Action of Gravity Field, compare oil-immersed type cooling motor, this mode cools the heat exchange cooling system of increase, comparatively oil-immersed type motor effect will be got well, but they have common defect to be exactly that rotor stirs cold oil when rotated and can cause the loss of motor power and the reduction of efficiency, especially during high speed, loss is larger.
Summary of the invention:
The purpose of this utility model is to provide a kind of novel oil-immersed type oil-cooled motor, and described this oil-cooled motor will to solve in prior art that cooling structure design in motor is unreasonable causes that cooling effectiveness is low, cold oil brings extra energy ezpenditure to motor, causes the technical problem of the reduction of the loss of motor power and efficiency.
This novel oil-immersed type oil-cooled motor of the present utility model, comprise rotor, front end housing, casing, armature, rear end cap and rotor, wherein, cooling oil jacket is provided with between described armature outer sidewall and internal side of shell wall, described cooling oil jacket is set in described armature outer sidewall, described cooling oil jacket and described armature and chassis contact, described cold oil puts and offers oil-in, what cold oil cover also offered cooling oil path and two ends distributes hydraulic fluid port, described oil-in is communicated with cooling oil path, described cooling oil path is communicated with the described hydraulic fluid port that distributes, the described hydraulic fluid port that distributes is communicated with oil-out, described oil-out is communicated with cooling oil box by oil pipe, the described hydraulic fluid port that distributes is communicated with cooling oil box by oil pipe, described oil-in is communicated with oil pump by oil pipe, oil pump makes the cold oil in fuel tank circulate between cooling oil jacket and fuel tank.
Further, the cooling oil path that described cold oil puts is spirality cooling oil path.
Further, described oil-in is located in the middle part of described cooling oil jacket, is equipped with distributes hydraulic fluid port at cooling oil jacket two ends.
Further, to be provided with along its circumferencial direction at described cooling oil jacket lateral wall and a plurality ofly to distribute hydraulic fluid port.
Further, described a plurality of hydraulic fluid ports that distribute are uniformly distributed along described cooling oil jacket circumferencial direction.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model adopts helical structure to cool the armature of oil jacket to motor and is cooled in motor, and the processing of spiral oil jacket structure is simple, and oil circulation does not intersect the object of the front and back shunting solving oil circuit; Spiral oil jacket leads to the heat radiation that oil solves armature central authorities; . it is better to armature ends radiating effect respectively that front and back distribute hydraulic fluid port; The cold oil (but not exceeding the height of rotor) of the inner submergence certain altitude of spiral oil jacket, better to whole armature heat radiation, rotor is at High Rotation Speed without cold oil resistance, and motor power loss is little; Cold oil is entered fuel tank and is circulated by oil pump, and the exchange achieving heat improves the radiating efficiency of motor.Existing motor can be made high power, high efficiency, high energy-saving environment protection by comprehensive above advantage, effectively reduces motor manufacturing cost.
