Latest Patents
Zitka's latest patents include a "Downhole Motor and Bearing Assembly" and a "Flexible Coupling for Downhole Motor." The downhole motor patent features a bearing assembly designed to allow rotational and bidirectional axial movement of a drive shaft within a housing. This assembly includes a stationary race member, a displaceable race member, ball bearings, and resilient load-carrying members that effectively distribute axial thrust loading. The design aims to provide a high axial thrust load capacity while preventing shock loading during sudden changes in axial loading direction.
The flexible coupling patent is intended for use in downhole motor assemblies, such as positive displacement moineau motors. It consists of two sets of flexible joints, each made up of cylindrically shaped slipper couplings that are angularly offset by 90 degrees. These slipper couplings are constructed from mating male and female members, joined by ball bearings positioned in arcuate grooves along the cylindrical mating surface.
