Однако указанный электропривод имеет сложную конструкцию и не позвол ет полу №Tb на выходе ускоренные обороты,However, this electric drive has a complex structure and does not allow the floor #Tb at the output to accelerate

Дл расширени функциональных возмо ностей привода и уменьшени габаритов подвижна втулка установлена между рото ром и корпусом двигател на полом валу, скрепленным с жестким колесом волновой передачи, а перемешаюший механизм выполнен в виде винта с поводковой шайбой, св занной через пазы полого вала с подвижной втулкой.To expand the functional capabilities of the drive and reduce the dimensions, the movable sleeve is installed between the rotor and the engine housing on the hollow shaft fastened to the rigid wave transmission wheel, and the mixing mechanism is made in the form of a screw with a driving washer connected through the slots of the hollow shaft to the movable sleeve.

Claims

The design of the stator 1 is similar to that of common industrial AC motors. Inside the rotor 2 of the engine, a reducing device is dispersed, consisting of a flexible wheel 3 connected to an output shaft 4, a rigid wheel 5 and a flexible bearing 6 playing the role of a mechanical wave generator. The rigid wheel is integral with a hollow shaft on which sleeve 7 is mounted for axial movement, for which the hollow shaft has grooves with which it engages with the drive washer 8. The end faces of the sleeve can engage with either a rotor or engine housing 9, depending on its axial position. The screw is screwed through the drive washer screw 10. For the purpose of creating a normal temperature mode of the engine, the end cover of the rotor can be made from the impellers; the electric drive works as follows. The fully screwed screw 10 moves the drive washer 8, and therefore the sleeve 7, to the left and engages the rotor

2. The hardwave wave transfer wheel 5 is non-idle. When the SRI of the stator winding is turned on, the rotor 2, depending on the design of the active layer, begins to rotate at asynchronous or synchronous speed, like a conventional machine. All elements of the wave transmission, and, consequently, and the output shaft of the engine, rotate at a speed equal to the speed of rotation of the rotor. To obtain a low speed, the screw 10 is turned off the output shaft. In this case, the sleeve 7 leaves the hook; laziness with the body of the rotor and enters with its protrusions into the recesses of the bearing, thereby stopping the rigid wave transfer wheel. The flexible bearing 6 rotating in conjunction with the rotor causes the wave deformation of the flexible wheel 3 and the output shaft associated with it, acquiring the VT slow rotation. For normal operation of the electric drive, when obtaining a normal rotational speed, the angle of inclination of the contacting surfaces of the rotor and sleeve must be such that, at maximum friction force, no seizing occurs. In the described electric drive, it is possible to obtain two output speeds using one standard stator, the combination of the same multi-speed stator allows us to obtain an even greater variety of gear ratios; It is possible to obtain a differential drive when removing load from both shafts. The dimensions of the proposed electric drive do not substantially differ from those of a conventional drive motor. An electric drive comprising a housing, an electric AC motor with a hollow non-winding rotor, inside which is placed a mechanical wave gearbox consisting of a flexible wheel connected to the output shaft, and a rigid wheel, axially movable sleeve and moving its mechanism, different so that, in order to expand the functional B03Mo; tb drive bridges and reduce overall dimensions, a movable sleeve is installed between the rotor and the motor housing on the hollow shaft fastened to the rigid wheel wave transmission, and the transfer mechanism is made in the form of a screw with a flood washer connected through the slots of the hollow shaft with a movable sleeve.
