Abstract
The utility model combines an outer rotor motor and a speed reducer of a harmonic gear, wherein the outer circle contour of a casing of the outer rotor motor is made into a cam shape, the casing of the motor and a waveform generator of the harmonic gear are combined into a whole, and the outer rotor motor is placed in the inner of a flexible gear of the harmonic gear. The gear speed reducing motor of the utility model has the advantages of simple structure and volume reduction.
Description
Affiliated technical field
External rotor harmonic gear motor of the present utility model is that external rotor electric machine is slowed down through harmonic gear reducer, obtains the slow-revving output of big moment, is used to drive rotatable parts.
Background technology
Reducing motor is along with the difference of motor and speed reducer has a lot of structures, and motor divides outer-rotor structure and inner rotor core, and the reductor kind has planetary gear bevel gear harmonic gear etc.Existing structure is that the output shaft by motor is connected with gear mostly, its complex structure, and volume is bigger.
Summary of the invention
In order to overcome the deficiency of existing servomechanism, the utility model provides a kind of novel structure solution, and this scheme can make the simple in structure of gear reduction motor.
The technical scheme that the utility model adopted is: motor is made outer-rotor structure, motor stamping is positioned over inside and is fixed in flange end and covers, coil is wound in the punching of internal fixation, permanent magnet is bonded on the rotation case of motor, the outer garden profile of motor housing is made cam structure, as the waveform generator of harmonic gear.
Will structure is done concise and to the point the description below
External rotor harmonic gear reducing motor structure as shown in Figure 1.The motor of Fig. 1 is the brushless, permanently external rotor electric machine, the flexbile gear output of harmonic gear, and firm wheel is fixed in flange end and covers.1 is the flange end cap among Fig. 1, and 2 is stator punching, and 3 is stator winding, and 4 is external rotor, and 5 and 6 is bearing, and 7 for being bonded to the permanent magnet on the shell, and 8 is flexbile gear, and 9 is flexible bearing, and 10 is just to take turns.
Change the permanent magnet among Fig. 1 into punching and bus, motor then is the external-rotor-type asynchronous machine, also can realize the purpose of this utility model.
Change the harmonic gear structure of Fig. 1 into internal tooth complex wave harmonic drive gear or flat harmonic gear, wheel output just also can realize the purpose of this utility model.
Embodiment
According to Fig. 1 structure, the outer garden profile of the shell of motor be made cam face, motor housing is as shown in Figure 2.Its inboard bonded permanent magnet or asynchronous machine punching and bus, flexible gear is placed in the outside, becomes the waveform generator of harmonic gear.
According to Fig. 3 structure, utilize screw that the external rotor electric machine shell and the cam of circle are combined, parts have the function of external rotor electric machine shell, and the function of harmonic gear waveform generator is also arranged, and also can realize the purpose of this patent.
Claims (1)
1. gear reduction motor, its architectural feature are that the cam with the shell of external rotor electric machine and harmonic gear waveform generator is combined into one, and external rotor electric machine are positioned over the flexbile gear inside of harmonic gear.
