Abstract

Square and D-shaped shafts are frequently used as driving members and require specific orientation relative to the drive member prior to assembly. This orientation is usually performed by human assemblers. This article describes an unmanned technique for coupling such shafts to driven members. A lead-in design for the driven member 4 is provided which permits the adaptability of automated equipment for this type of assembly. The contour of the lead-in 4 is generated through a dual opposite 45Πrotation of the square shaft 2 over a specific interval. The entrance of the driven member 4 has a diameter slightly larger than that of the square shaft 4 across its corners. The end of square shaft 2 is broken, as shown in the illustration.

Drive Shaft Alignment

Square and D-shaped shafts are frequently used as driving members and require specific orientation relative to the drive member prior to assembly. This orientation is usually performed by human assemblers. This article describes an unmanned technique for coupling such shafts to driven members. A lead-in design for the driven member 4 is provided which permits the adaptability of automated equipment for this type of assembly. The contour of the lead-in 4 is generated through a dual opposite 45OE rotation of the square shaft 2 over a specific interval. The entrance of the driven member 4 has a diameter slightly larger than that of the square shaft 4 across its corners. The end of square shaft 2 is broken, as shown in the illustration. The square shaft 2 may enter the round driven member 4 with rotational misalignment, but the two will align with each other as a result of their relative rotating and camming action.
