Description
Technical field
The utility model belongs to decelerator field, is specifically related to a kind of electric motor built-in decelerator.
Background technology
Two kinds of forms of the many employings of current motor reducer used, the one, motor output shaft is directly connected with reducer input shaft; The 2nd, conventional inner rotor motor and decelerator are integrated in reducer shell, rotor is connected with the power shaft of reducing gear.Yet the motor reducer axial dimension that these two kinds of modes form increases particularly evident, causes volume obviously bigger than normal.Seriously limited while using in such as electric motor car, electro-tricycle, electric automobile etc. has the equipment of strict demand to motor reducer volume, this be need improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind of motor is integrated in reducer shell, can realize high pulling torque output, the electric motor built-in decelerator that takes up room little.
For addressing the above problem, the technical scheme that the utility model adopts is.
Electric motor built-in decelerator, comprise motor reducer housing (22) and be arranged at the reducing gear in motor reducer housing (22), it is characterized in that: it also comprises motor stator (12) and rotor (3), described motor stator (12) is internal stator, is fixed in motor reducer housing (22); Rotor (3) is external rotor, and outside suit gear wheel (23), with output gear (1) external toothing of reducing gear.
Press such scheme, described rotor includes motor rotor punching sheet in (3), and the form with spline between motor rotor punching sheet and gear wheel (23) connects.
Press such scheme, described gear wheel (23) can be spur gear, helical gear, bevel gear, worm screw.
Compared with prior art, the utility model has the advantage of: this electric motor built-in decelerator is by being integrated in motor in motor reducer housing, and space availability ratio is high, and axial dimension is little.Meanwhile, this electric motor built-in decelerator adopts the mode of external rotor electric machine overcoat gear, it is increased in unidimensional situation lower rotor part moment of inertia, thereby improved the output torque of decelerator, realizes high pulling torque output.
