Abstract
A thrust chamber for use in a horizontal hurst apparatus or other pump apparatus is disclosed. The thrust chamber includes a housing, a rotatable shaft mounted within the housing, a first downthrust bearing section connected to the shaft and to the housing, and a second downthrust bearing section also connected to the shaft and the housing. The two downthrust bearing sections are interconnected so that as a downthrust load is placed on the shaft, the first downthrust bearing section receives the load and engages the second downthrust bearing section so as to share the load substantially equally between the first downthrust bearing section and the second downthrust bearing section. Each downthrust bearing section is substantially alike and additional downthrust bearing sections may be added as desired. The thrust chamber further includes an upthrust bearing section, connected to the shaft and the housing. The upthrust bearing section provides pre-loading of the shaft so as to apply a load to the first downthrust bearing section and the second downthrust bearing section. A lubrication unit is also provided that utilizes apertures and channels within the various sections within the th…
