Abstract
Disclosed is an apparatus for shifting a phase between shafts in an internal combustion engine. A phase shifting device for shifting a rotational phase of the driven shaft to the drive shaft and an amplifying gear mechanism having a plurality of gears are disposed between the drive shaft and driven shaft. The amplifying gear mechanism amplifies the amount of phase shifting when the phase shifting is made by the phase shifting device and rotates all the gears integrally when no phase shifting is made.
Claims19
An apparatus for shifting a phase between shafts in an internal combustion engine, comprising:
- a drive shaft;
- a driven shaft;
- a phase shifting means for shifting a rotational phase of the driven shaft to the drive shaft between the drive shaft and driven shaft;
- and
- an amplifying gear means having a plurality of gears, for amplifying an amount of a phase shift when the phase shift is made by the phase shifting means and rotating all the gears integrally when no phase shift is made.
An apparatus for shifting a phase between shafts in an internal combustion engine, comprising:
- a drive shaft;
- a driven shaft;
- a power transmitting means for transmitting power from the drive shaft to the driven shaft;
- a phase shifting means for shifting a rotational phase of the driven shaft to the drive shaft between the drive shaft and driven shaft;
- and
- an amplifying gear means having a plurality of gears, for amplifying an amount of phase shifting when the phase shift is made by the phase shifting means and rotating all the gears integrally when no phase shift is made.
An apparatus for shifting a phase between shafts in an internal combustion engine, comprising:
- a drive shaft;
- a driven shaft;
- a pulley fixed on one of the drive shaft and the driven shaft, with a belt for transmitting the rotation of the drive shaft to the driven shaft being put around the pulley;
- a first gear secured on the one of the drive shaft and driven shaft;
- a second gear provided on an inner surface of the pulley;
- a third gear, disposed between the first and second gears, for engaging with the first and second gears;
- a support member for supporting the third gear;
- and
- a coupling member for coupling the support member to the pulley, the coupling member being coupled by means of a spline to the support member and the pulley so as to be movable only in an axial direction, and being coupled by a helical spline to at least one of the support member and the pulley, an amount of phase shifting being amplified in accordance with a ratio of the diameter of the first gear to that of the third gear.
