Abstract: A keyless timing gear assembly for securing a bull gear to a crankshaft of a power end of a reciprocating pump assembly, the keyless timing gear assembly including at least one actuator, an expansion member and at least one wedge member disposed between the at least one actuator and the expansion member, the wedge member having a sloped surface to slideably engage a corresponding sloped surface on the expansion member such that, in response to actuation of the at least one actuator, the at least one wedge member exerts a force on the expansion member for securing a bull gear to a crankshaft.

Abstract: A fluid delivery device for a hydraulic fracturing system includes a fluid conduit having a fracking fluid outlet configured to be fluidly connected to a well head for delivering a fracking fluid to the well head. The fluid conduit includes a base fluid inlet configured to be fluidly connected to the outlet of a frac pump such that the fluid conduit is configured to receive a flow of base fluid from the frac pump. An injection system is fluidly connected to the fluid conduit downstream from the base fluid inlet and upstream from the fracking fluid outlet. The injection system is configured to be fluidly connected to a material source. The injection system is configured to inject at least one material of the fracking fluid from the material source into the fluid conduit downstream from the frac pump to generate the fracking fluid within the fluid conduit.
