Abstract
A two speed windlass includes a driving shaft, a clutch and a planetary gear speed reducing mechanism. The clutch is used to connect the driving shaft to the planetary gear speed reducing mechanism to control the speed of the driving shaft The speed of the two speed windlass, thus, can be reduced by the speed reducing mechanism. The integral speed also can remain the same by synchronously driving the speed reducing mechanism.
Claims3
A two speed windlass, comprising
- a power source;
- a driving shaft having a first end connected to the power source and a second end opposite to the first end;
- a hollow shaft having a first end to allow the second end of the driving shaft to pass therethrough, the hollow shaft being located on a stand by a first bearing and having a second bearing therein to allow the driving shaft to rotatably pass therethrough, the hollow shaft further having a second end opposite to the first end;
- a clutch mounted between the first end of the hollow shaft and the power source and rotating together with the driving shaft so as to allow the clutch to rotate together with the hollow shaft when the clutch actuates;
- a planetary gear speed reducing mechanism having a circular gear encircling therearound and a first side connected to the second end of the hollow shaft by a side of the circular gear, the second end of the driving shaft extending through a center of the planetary gear speed reducing mechanism to reduce a driving speed from the driving source, and the planetary gear speed reducing mechanism having a second side opposite to the first side;
- and
- a delivery shaft driven by the second side of the planetary gear speed reducing mechanism and driving a reel so as to rotate together with the reel, and a rope-like body winding a surface of the reel.
