Embodiment Construction
[0020] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples, but the present invention is not limited.
[0021] figure 1 The process diagram showing the axial position and dimension of the semicircular keyway is expressed by the partial section view of the front view and the left view. D is the diameter of the circle where the shaft of the semicircular keyway is located, and L is the axial distance from the centerline of the arc of the shaft of the semicircular keyway to the reference plane.
[0022] figure 2 It shows the schematic structure of the present invention when it is used. A detection tool for measuring the axial position and size of the semicircular keyway of the crankshaft includes a gauge block 1 and a gauge 2. The gauge block 1 has a flat circular shape, and its thickness is designed according to the width of the keyway. Circular diameter The arc diameter design of the key sl...
