摘要:
Some embodiments include a novel power transmission joint system that is low in cost and can withstand extended wear. The power transmission joint system has several components including a drive cup, a drive shaft pin, and a large contact area between the drive cup and the drive shaft pin. The drive shaft pin is a pivoting pin that provides a second pivot axis to reduce wear on the system. The large contact area is larger than a corresponding contact area of an existing low-cost pinned drive shaft, drive cup system. The large contact area significantly reduces pressure on the system. The power transmission joint system can withstand extended wear and tear.
