変速機付き圧縮機
Document Type and Number:
Japanese Patent JP5310630
Kind Code:
B2
Abstract:
A compressor includes a housing, a compression mechanism formed in the housing and operable to compress refrigerant, an input shaft extending into the housing from outside and rotatably supported on an axis of the input shaft, an output shaft extending in the housing and rotatably supported on the axis for driving the compression mechanism, a transmission provided in the housing between the input shaft and the output shaft for transmitting torque from the input shaft to the output shaft and also changing the rotating speed of the input shaft into two different speeds of the output shaft for driving the compression mechanism by increasing or remaining the rotating speed of the input shaft and a control device. The transmission includes a plurality of planetary rollers, a carrier rotatably supporting the respective planetary rollers and being integrally rotatable with the input shaft, a sun roller engaged with the respective planetary rollers and integrally rotatable with the output shaft and a ring roller engaged with the respective planetary rollers. The ring roller can be fixed to the housing or rotatable relative to the housing. The control device provided between the carrier and the ring roller for controlling the operation of the transmission includes a one-way clutch provided between the ring roller and the carrier and allowing the ring roller to rotate only one direction relative to the carrier and a clutch provided between the housing and the ring roller, the clutch fixing the ring roller to the housing or allowing the ring roller to rotate relative to the housing. The ring roller includes a first ring engaged with the respective planetary rollers and a second ring supporting the one-way clutch. The ring roller can be movable relative to the housing in the direction parallel to the axis. The first ring and the second ring are connected so that the first ring can be displaced in a radial direction, integrally rotatable with the second ring and movable with the second ring in the direction parallel to the axis.
