Abstract

See full text

A pump and motor assembly (20) includes a centrifugal pump (30), a bent axis hydraulic pump 58, and a wet-type drive motor (228). The motor has a rotor and a stator that are submerged in hydraulic fluid for full lubrication and cooling. A drive shaft 66 is driven by the motor. The centrifugal pump has a rotatable impeller (50) for pumping hydraulic fluid from an inlet (48) to the bent axis hydraulic pump. The centrifugal pump also pumps fluid to the motor for lubrication and cooling. The bent axis hydraulic pump pumps the fluid and discharges the fluid from the system. The centrifugal pump and the bent axis hydraulic pump are rotatable along a common rotational axis R1 that is angled relative to the rotational axis R2 of the drive shaft.
