Fixed Bent Housing, Bottom Seal Cap and Adjust Ring of a mud motor
The subject merchandise includes four components of a mud motor (“the components”). The components include:
Fixed Bent Housing – a steel alloy component with a specified/pre-bent angle that cannot be adjusted (unlike adjustable housings). Orients the mud motor and drill bit downhole to allow the mud motor to be used in directional drilling.
Bottom Seal Cap – a steel alloy component cap that locks the seal boot in place. The bottom seal cap and seal boot keep the drive shaft from coming out of the bearing adaptor.
Adjust Ring – a grooved ring made of a steel alloy which allows the mud motor to be set to a desired angle and locked into place for directional drilling. The adjust ring contains marking indicators that line up with marking indicators on the offset housing, permitting the rig operator to adjust the angle of the mud motor.
Offset Housing – a grooved, steel alloy component that allows the mud motor to be set to a desired angle and locked into place for directional drilling. The offset housing contains marking indicators that line up with marking indicators on the adjust ring, permitting the rig operator to adjust the angle of the mud motor.
A mud motor is comprised of a variety of components that are categorized as either stationary or rotating. The rotating components are housed inside of the stationary components during drilling operations. The subject adjust ring, offset housing, and fixed bent housing components are of the stationary category, while the subject bottom seal cap is a component of the rotating category. All the subject components are found between the power section of the mud motor, which consists of the rotor and stator found at the top of the mud motor, and the drill bit to which the mud motor ultimately powers.
