Rotary motor

Abstract

The present invention provides a dynamoelectric machine which is small in size and whose transmission part can be fed with oil. This dynamoelectric machine has a rotor 11, a stator 12, and a casing 18. A planetary roller mechanism comprising a sun roller 15, a planetary roller 16, a ring roller 13, and a carrier 17, is placed inside the rotor 11 to transmit a driving force of the rotor 11 from a power shaft 19 to the outside. Oil is sealed inside the rotor 11 or inside the casing 18. Or, the planetary roller mechanism is placed inside the casing 18 or outside the rotor 11 and oil is sealed in the casing 18.

Description

technical field [0001] The present invention relates to a rotating electric machine such as a motor or a generator, and particularly relates to a rotating electric machine in which a transmission mechanism and a mechanism for synthesizing multi-axis rotating power are housed in the rotating electric machine. Background technique [0002] As an industrial motor, geared motors (ギアドラータ) are widely produced and sold, in which a speed change gear is provided on the output shaft of the motor, and the rotation speed is changed to the speed of the desired load power to output the rotational power. Generally, the gear mechanism of a gear motor is relatively large, so it is known, for example, in Japanese Patent Application Laid-Open No. 10-210709 and Japanese Patent Laid-Open No. 2001-12563 that a speed change mechanism is provided inside a rotating electric machine to make it compact. technology. [0003] However, what is described in JP-A-10-210709 and JP-A-2001-12563 is that, as ...

Problems solved by technology

[0003] However, what is described in JP-A-10-210709 and JP-A-2001-12563 is that, as the speed change mechanism, a meshing transmission such as a gear train, a toothed belt, and a friction transmission gear train is used. non-uniform rotation

When meshing transmission elements are used inside the rotating electrical machine, the vibration-absorbing buffer area cannot be secured due to the small size of the parts, and the disturbance to the rotor of the rotating electrical machine is increased compared with the case where a speed change mechanism is provided outside the rotating electrical machine

In recent years, the gap between the rotor and the stator of the rotating electric machine has become smaller for the purpose of increasing efficiency. Therefore, it is necessary to strengthen the bearing to prevent the contact between the rotor and the stator caused by the vibration. When the bearing is strengthened, the Solved the problem of large-scale rotating electrical machines
