Abstract
An apparatus for assembling a crankshaft-sprocket aligns a timing mark of a sprocket to a predetermined line of a crankshaft, and includes a slider for slidably moving an interior circumference surface of the sprocket to an exterior circumference surface of the crankshaft. A guider is disposed on an end portion of the crankshaft so as to guide the slider to the crankshaft. A first aligner is disposed on the slider so as to align the timing mark of the sprocket to a predetermined portion of the slider. A second aligner aligns the slider such that the timing mark aligned by the first aligner is positioned to the predetermined line of the crankshaft.
Claims9
An apparatus for assembling a crankshaft-sprocket such that a timing mark of a sprocket is positioned to a predetermined line of a crankshaft, comprising:
- a slider for slidably moving an interior circumference surface of the sprocket to an exterior circumference surface of the crankshaft, after holding the sprocket;
- a guider disposed on an end portion of the crankshaft so as to guide the slider to the crankshaft;
- a first aligner disposed on the slider so as to align the timing mark of the sprocket to a predetermined portion of the slider;
- and
- a second aligner for aligning the slider such that the timing mark aligned by the first aligner is positioned to the predetermined line of the crankshaft.
A method for assembling a crankshaft-sprocket, comprising:
- aligning a predetermined portion of an end potion of a guider to an end portion of a crankshaft using a second aligner;
- aligning a timing mark of the sprocket to predetermined portion of a slider using a first aligner, after inserting the sprocket into the slider;
- thrusting the aligned sprocket onto the crankshaft, after inserting the slider into the guider;
- releasing the first aligner and drawing out the slider, after the sprocket is fixed to the crankshaft;
- and
- releasing the second aligner and separating the guider from the crankshaft.
