Rotor and universal joint assembly

A progressive cavity pump includes a sealed drive between the rotor and universal joint. The universal joint includes a socket configured to receive a drive shaft of the rotor. A cover, such as a locking nut, is disposed over the connection between the rotor and universal joint. Seals are retained in place by the locking nut to prevent abrasive materials from entering into the interface between the rotor and the universal joint.

Sealed drive for connecting progressive cavity pump rotors to universal joints

A cutter head assembly for a fiber roving chopper includes a cylindrical blade cartridge extending axially between a cartridge first end and a cartridge second end. The cylindrical blade cartridge includes a first surface that extends between the cartridge first and second ends and is angled with respect to a central axis of the cylindrical blade cartridge. A second surface extends between the cartridge first and second ends parallel to the first surface and the second surface faces the first surface. A blade body extends between the cartridge first end and the cartridge second end and is disposed between the first surface and the second surface.
