摘要： A compressor provided with a compressor element with a driven shaft, a motor with a drive shaft to drive the compressor element, and a transmission between the drive shaft and the driven shaft. The transmission includes a housing and at least a driven gearwheel that is mounted on the driven shaft and a drive gearwheel that is mounted on a drive shaft. The housing includes two separated chambers, a first chamber that is connected to the driven shaft and a second chamber which is separate from the first chamber. The first chamber is connected via a channel with the second chamber, whereby around the drive gearwheel or driven gearwheel, the second chamber is formed. The form of the second chamber is such that when the gearwheel in question rotates, a gas flow is created around this gearwheel which causes a negative pressure in the channel by the venturi effect.

摘要： Systems and methods for controlling transmissions having CVTs are disclosed with multiple modes and gearing arrangements for range enhancements, where embodiments include synchronous shifting to allow the transmission to achieve a continuous range of transmission ratios, while minimizing “empty” cycling of the CVT during mode shifts. Embodiments provide for wide ratio range and performance and efficiency flexibility, while maximizing CVT usage through synchronous shifting.

摘要： A speed reducer includes an outer tubular member, internal tooth pins, oscillating gears and a carrier block. The outer tubular member has pin grooves on an inner circumferential surface thereof. The internal tooth pins are rotatably placed in the pin grooves. The oscillating gears have external teeth smaller in number than the pin grooves, and the oscillating gears are oscillatorily rotatable with the external teeth engaging with the internal tooth pins. The carrier block is cooperatively connected to the oscillating gears such that the oscillating gears are allowed to oscillatorily rotate relative to the carrier block and restricted from rotating on own axis relative to the carrier block. A displacement restricting member configured to restrict the internal tooth pins from being displaced inwardly in a radial direction of the outer tubular member is disposed between the outer peripheries of the oscillating gears adjacent to each other.

摘要： A first driving device includes a motor including a rotating shaft, a speed reducer, and a supporting member. The speed reducer includes a rigid gear, a flexible gear configured to partially mesh with the rigid gear, and a wave motion generator coupled to the rotating shaft and configured to come into contact with the inner circumferential surface of the flexible gear, bend the flexible gear, and move a meshing position of the rigid gear and the flexible gear in the circumferential direction. The wave motion generator includes a projecting section projecting along the rotating shaft. The rotating shaft is supported by the supporting member via a bearing including an inner ring and an outer ring. The outer ring of the bearing is supported by the supporting member. The rotating shaft and the projecting section are coupled to the inner ring of the bearing by tight fitting.

摘要： A transmission system includes planetary gearing with a ring gear, a plurality of planet gears, a carrier, and a sun gear, a forward clutch operatively connected between the ring gear and carrier, a reverse brake operatively connected between the carrier and a rotationally fixed location, and a control subsystem to switch the transmission system between forward and reverse operational modes in the which the ring gear and the sun gear rotate in the same or opposite rotational directions, respectively. A control subsystem actuation stroke can actuate both the forward clutch and the reverse brake based on a common control signal.

摘要： A transmission element for transferring torque from a set of sprockets to a bicycle rear wheel hub bearing-supported on a wheel axle is equipped with a first interface for coupling to the sprocket. This first interface is arranged such that it secures the sprocket or the cassette to the driver in axial and/or radial and/or tangential direction. The driver is furthermore equipped with a second interface for coupling to the sprocket. The second interface is arranged such that it secures the sprocket to the driver in axial and/or radial and/or tangential direction. The second interface is then present in a larger diameter than the first interface.
