Reduction device

A reduction device configured in such a manner that roller guiding bearings which are pressure-fitted on the eccentric circular plates of the input shaft is stably installed to suppress a reduction in the efficiency due to the coming out of the bearings. An input shaft (7) is disposed so as to be coaxial with a stationary internal gear (3), two eccentric circular plates (9) which can rotate within the internal gear (3) are provided to the input shaft (7), and roller guiding bearings (11) are pressure-fitted on the respective outer diameter surfaces of the eccentric circular plates (9). A cage (15) which can rotate between the internal gear (3) and the eccentric circular plates (9) is provided to a shaft end section of the output shaft (12) which is disposed coaxially with the input shaft (7). Roller containing pockets (18), the number of which is less than the number of the internal teeth (4) of the internal gear (3), are formed in the cage (15). Rollers (19) are individually received within the roller containing pockets (18). The rotation of the eccentric circular plates (9) which rotate together with the input shaft (7) sequentially engages the rollers (19) with the internal teeth (4). One rotation of the input shaft (7) moves the rollers (19) in the circumferential direction by a distance corresponding to a tooth of the internal teeth (4) to rotate the output shaft (12) at a reduced speed. A circular protrusion (21) is provided between the two eccentric circular plates (9), and staking protrusions (22) are provided at axially opposing ends of the eccentric circular plates (9). The staking protrusions (22) and the annular protrusion (21) prevent the bearing (11) from moving in the axial direction.

Electric motor for compressor, compressor, and freezing cycle device

An object is to provide an electric motor for a compressor starting torque for which can be increased with the rise of the price of a component and a deterioration in efficiency in operation suppressed. The electric motor for the compressor is housed with a compressor element for compressing a cooling medium in an airtight container and connected to the compressor element via a driving axis to drive the compressor element. The electric motor for the compressor comprises a stator fixed to the inner periphery portion of the airtight container, a rotator (11) which is arranged on the inner side of the stator and which has a rotator core (11a), and a double squirrel-cage conductor which is cast in the rotator core (11a) and which is constituted by a secondary conductor comprising an outer layer secondary conductor and an inner layer secondary conductor and an end ring (32). In the rotator core (11a), an air hole (33) which is the passage of the cooling medium is provided. The inner diameter side of the end ring (32) is enlarged to a driving axis side in such a manner that the air hole (33) is sealed. The end ring (32) has a cutting (34) for allowing the air hole (33) to be communicated with the space of the airtight container so as not to seal the air hole (33).

Technical field of method of controlling electric vehicle and drive system of electric vehicle

A drive system of an electric vehicle includes: an internal combustion engine; a generating motor provided so as to be able to generate electricity by receiving motive force from the internal combustion engine; and a travel motor provided so as to be able to be driven by electric power generated by the generating motor, and the drive system is configured so as to be able to switch a series hybrid mode and an engine direct connected mode, the series hybrid mode being a mode in which, while the internal combustion engine and the drive wheel are linked via a first clutch so as to be unlinkable/linkable, the travel motor and the drive wheel are linked via a second clutch different from the first clutch so as to be unlinkable/linkable, and the travel motor is used as a drive power source such that the electric vehicle travels by transmitting motive force from the travel motor to the drive wheel, the engine direct connected mode being a mode in which at least one of the internal combustion engine and the generator is used as a drive power source such that the electric vehicle travels by transmitting motive force from the drive power source to the drive wheel. At a mode switching time from the engine direct connected mode to the series hybrid mode involving deceleration, when the rotation synchronization or the engagement of the second clutch on an engagement side is not completed before the vehicle speed is decelerated to a predetermined vehicle speed, the first clutch on a disengagement side is disengaged before the engagement of the second clutch is completed.
