Marine Propulsion Isolation System For Control Of Motion Due To Torque And Related Method
US Patent:
6623318, Sep 23, 2003
Filed:
Nov 28, 2000
Appl. No.:
09/724011
Inventors:
Robert Arvid Kantola - Atkinson NH
Assignee:
General Electric Company - Schenectady NY
International Classification:
B63H 2130
US Classification:
440 52, 248562, 248566, 248636, 440111
Abstract:
Torque roll, such as in a marine propulsion unit for driving a propeller, is significantly reduced or substantially eliminated by utilizing inflatable elements, such as airbags. One or more airbags engage the top of a propulsion unit mounting surface supported by an elastomeric isolation mount where a torque roll force is substantially upward, and one or more other airbags engage the bottom of a mount for the propulsion unit at a location where the torque roll force is substantially downward. The amount of gas supplied to the airbags is preferably substantially proportional to the torque roll force at each of the airbags. By significantly reducing or substantially eliminating the torque roll of the propulsion unit, the unit can be connected to other components without line shaft couplings.
