Abstract

A two-piece axle bushing for marine propeller includes a first transmission member including an accommodation chamber and longitudinal inner ribs spaced around an inner perimeter of the accommodation chamber, and a second transmission member, which includes a tube shaft that includes a first transmission segment inserted into the accommodation chamber and including longitudinal outer ribs spaced around the outer perimeter thereof and respectively movably inserted into one respective buffer space of the first transmission member and selectively engageable with one respective longitudinal inner rib and a second transmission segment connected to the first transmission segment, and a shock absorber fixedly surrounding the outer perimeter of the second transmission segment. Thus, the two-piece axle bushing of the present invention can generate power hysteresis effects when the engine starts up, reducing vibration due to a sudden high torque and further enhancing marine propeller start-up stability and smoothness.
