Whatever it was, I was done for the day. I later discovered that a coupler between the engine shaft and the hydraulic pump failed dramatically. It was an easy fix once I ordered the right part ...

Interfacing a shaft to a 3D printed gear doesn’t have to be tricky. [Tlalexander] demonstrated a solution that uses one half of a spider coupling (or jaw coupling) to create an effective modular ...

Flexible couplings couple or connect rotating members such as motors and drive shafts while allowing misalignment in either angular or parallel offset orientation. Sliding blocks are slotted or jawed ...

Similarly, parallel misalignment tolerance is the maximum parallel offset between shafts that rigid couplings can accommodate. Axial motion allowed refers to the relative axial motion allowed by the ...
