  • Submersible pump assembly for downhole use
    Patent number: 6357552
    Abstract: A submersible pump assembly comprises a gear transmission (10) and an equalizer (24). The gear transmission (10) includes a transmission housing (12) filled with lubricating fluid in which an input shaft (14, 102, 120) adapted to be driven and an output shaft (16) for driving a pump are supported. A transmission step (22) is provided to reduce the rotational speed of the input shaft (14, 102, 120). The equalizer (24) adapts the lubricating fluid pressure in the transmission housing (12) to ambient pressure. The equalizer (24) is arranged within the transmission housing (12) next to the transmission step (22) so as to distribute the heat generated at the transmission step (22) throughout the lubricating fluid.
