Abstract
The present invention discloses a power transmission apparatus. The power transmission apparatus includes: an input shaft including a male screw portion formed thereon; a pair of input gears formed on the input shaft to be freely rotatable with the male screw portion being interposed therebetween; an output gear formed to be rotatable in a state of being linked with the pair of input gears; and a power interrupting unit screw-coupled to the male screw portion of the input shaft, and configured to rectilinearly reciprocate along the input shaft by a rotation of the input shaft to be selectively engaged with any one of the pair of input gears so as to transmit a power.
Claims16
A power transmission apparatus comprising:
- an input shaft including a male screw portion formed thereon;
- a pair of input gears formed on the input shaft to be freely rotatable with the male screw portion being interposed therebetween;
- an output gear formed to be rotatable in a state of being linked with the pair of input gears;
- and
- a power interrupting unit screw-coupled to the male screw portion of the input shaft, and configured to rectilinearly reciprocate along the input shaft by a rotation of the input shaft to be selectively engaged with any one of the pair of input gears so as to transmit a power,
- wherein the pair of input gears are formed to have different diameters, and an input gear having a smaller diameter is linked with the output gear through an idle gear.
A power transmission apparatus comprising:
- an input shaft including a male screw portion formed thereon, and configured to be rotatable in a forward/reverse direction;
- a power interrupting unit screw-coupled to the male screw portion, and configured to rectilinearly reciprocate along the input shaft by a rotation of the input shaft;
- a pair of input gears formed on the input shaft to be freely rotatable with the power interrupting unit being interposed therebetween, and configured to be selectively engaged with the power interrupting unit to be rotated according to a movement of the power interrupting unit;
- and
- an output gear formed to be rotatable in a state of being selectively linked with the pair of input gears,
- wherein both the pair of input gears configured to be selectively engaged with the power interrupting unit to be rotated are rotated in a same direction, and
- wherein the pair of input gears are formed to have different diameters, and an input gear having a smaller diameter is linked with the output gear through an idle gear.
A power transmission apparatus comprising:
- an input shaft including a male screw portion formed thereon;
- an input gear formed at a side of the input shaft to be freely rotatable;
- an output gear formed to be divided into an inner gear portion that is coupled to be rotatable in a state of being linked with the input gear, and an extension portion that extends from the inner gear portion in a direction of the input shaft, and is coupled to the input shaft to be freely rotatable;
- and
- a power interrupting unit coupled to the male screw portion of the input shaft, and configured to rectilinearly move along the input shaft by a rotation of the input shaft to be selectively engaged with the input gear or the extension portion of the output gear so as to transmit a power,
- wherein the input gear is linked with the inner gear portion through a planetary gear.
A power transmission apparatus comprising:
- an input shaft including a male screw portion formed thereon, and configured to be rotatable in a forward/reverse direction;
- a power interrupting unit screw-coupled to the male screw portion, and configured to rectilinearly reciprocate along the input shaft by a rotation of the input shaft;
- an input gear formed on the input shaft to be freely rotatable, and configured to be engaged with the power interrupting unit to be rotated according to a movement of the power interrupting unit;
- and
- an output gear formed to be divided into an inner gear portion that is coupled to be rotatable in a state of being linked with the input gear, and an extension portion that extends from the inner gear portion in a direction of the input shaft, and is coupled to the input shaft to be freely rotatable,
- wherein a rotation of the input gear selectively engaged with the power interrupting unit and a rotation of the output gear by a rotation of the extension portion are performed in a same direction, and
- wherein the input gear is linked with the inner gear portion through a planetary gear.
