Appl. No.:

17/465471

Inventors:

- Casper WY, US
Patrick Daniel Gallagher - Mills WY, US
Daniel Robert Gallagher - Casper WY, US
Krista D. Anderson - Evansville WY, US

International Classification:

F16D 3/18
E21B 4/02
E21B 17/03

Abstract:

A universal joint (U-joint) assembly transmits torque from a drive component to a driven component across an articulating joint. The U-joint assembly includes male and female U-joint members, a central ball joint, and a retaining device configured to secure the assembly in an assembled configuration. The female U-joint member includes a cavity extending into a receptacle end thereof. The cavity terminates in a circular receptacle and includes a plurality of rectangular channels extending radially outward from the cavity at equal intervals, each channel defined by three planar drive surfaces. The male U-joint member has a drive end with a plurality of corresponding rectangular extensions protruding from an outer periphery of the drive end, each extension including a plurality of axial angular surfaces. When assembled, each of the angular surfaces of the drive end opposes a corresponding one of the drive surfaces of the cavity. Other embodiments are also disclosed.
