  • Patent number: 12258849
    Abstract: An arrangement for supporting one or more bearings of a crankshaft assembly of a hydraulic fracturing pump includes a frame and one or more bearing supports. The frame is of a first material and defines one or more bearing support profiles. The bearing supports are of a second material different from the first material of the frame. The bearing supports are cast-in-place within the corresponding bearing support profiles of the frame and are configured to be in contact with an outer race of the corresponding bearings of the crankshaft assembly. Compared to the first material of the frame, the second material of the bearing supports is more effective at preventing slippage of the bearings.

  • Patent number: 12249531
    Abstract: A method for forming a semiconductor structure is provided. The method includes forming a contact feature over an insulating layer, forming a first passivation layer over the contact feature, and etching the first passivation layer to form a trench exposing the contact feature. The method also includes forming an oxide layer over the contact feature and the first passivation layer and in the trench, forming a first non-conductive structure over the oxide layer, and patterning the first non-conductive structure to form a gap. The method further includes filling a conductive material in the gap to form a first conductive feature. The first non-conductive structure and the first conductive feature form a first bonding structure. The method further includes attaching a carrier substrate to the first bonding structure via a second bonding structure over the carrier substrate.

  • Publication number: 20240254987
    Abstract: A pump assembly may include a bearing housing having a bore. The pump assembly may include a connecting rod connected to the bearing housing at a first end of the connecting rod and connected to a crosshead at a second end of the connecting rod via a wrist pin. The connecting rod may include a lubrication channel that extends within the connecting rod. The pump assembly may include a shell bearing in the bore of the bearing housing, the shell bearing having an inner surface and an outer surface. A portion of the inner surface of the shell bearing that contacts the crankshaft in a forward stroke of the crosshead may be uninterrupted by a groove or an aperture configured to direct lubrication fluid to the lubrication channel of the connecting rod.
