In view of this, the purpose of this utility model provides a kind of combined liquid oil lubrication motor, adopts the hydrodynamic lubrication oil lubrication between the running gear friction pair, can prolong the useful life of motor greatly, saves maintenance cost.
Combined liquid oil lubrication motor of the present utility model, comprise casing, stator and rotor, described motor stator is fixedly installed in the casing, rotor and power output shaft are in the circumferencial direction secure fit, the power output shaft cylindrical cooperates with the right side and the left side of casing by first annular bearing with rolling contact and second annular bearing with rolling contact, and described first annular bearing with rolling contact passes through sealing ring II and box sealing by sealing ring I, second annular bearing with rolling contact; First annular bearing with rolling contact and second annular bearing with rolling contact are by the lubricant reservoir of sealing ring I and sealing ring II formation and box sealing.
Further, described casing one end face seal, the other end is provided with the tubular boss, and described tubular boss outer surface along the circumferential direction is provided with annular seal groove, and the o RunddichtringO is set in the annular seal groove;
Further, described motor is an external rotor electric machine, rotor walk around stator after the power output shaft bending with power output shaft in the circumferencial direction secure fit;
Further, described motor is an inner rotor motor, described power output shaft is a solid shafting, described power output shaft axle center is provided with vertical penetrating oilhole, and penetrating oilhole is communicated with the transmission oil chamber that motor is connected and communicates with the lubricant reservoir of first annular bearing with rolling contact and second annular bearing with rolling contact respectively;
Further, described sealing ring I and sealing ring II are outside framework oil seal;
Further, described housing plate outer surface is provided with fin.
The beneficial effects of the utility model are: combined liquid oil lubrication motor of the present utility model, employing is provided with the structure of sealing ring in the power take-off lever bearing inboard, on bearing, form and seal lubricant reservoir preferably, lubricant reservoir communicates with lubricating oil in the gearbox, therefore adopt the hydrodynamic lubrication oil lubrication between the running gear friction pair, can prolong the useful life of motor greatly, save maintenance cost, this structural design is ingenious, realizes that under the condition of cost that does not increase car load liquid oils is lubricated.
