Below is a brief overview; the full patent documents were prepared by Cullens-Patent Attorneys Brisbane, QLD Australia.

There has lately been considerable focus placed on increasing efficiency in industry, manufacturing, engineering processes, equipment and parts, motors and heavy machineries, right across the spectrum; in order to reduce power consumption, reduce emissions and carbon footprints, reduce maintenance and repairs, and to prolong equipment life-cycles at the same time as increase productivity. This focus is currently confined by the technical limitations of specific machinery and the very limited availability of an ‘off-the-shelf’ solution to critical elements used in these fields, its availability and existence.

 

The Torque Reversal and Clutch Gear Coupling (also referred to as kwokgear) is aimed as an ‘off-the-shelf’ device, or devices, that are common in the above fields as well as beyond the applications of  those spheres; for a device that allows torque-reversal on a shaft viz. having two-directional torque-rotations, preventing an opposing torque. This invention is a mechanical device and is self-actuated; it operates automatically and naturally.

The examples listed below are brief, however, the invention’s world-wide applications are limitless; including for bio-engineering, bio-medical and associated apparatus, automotive, engines and gearboxes, aeronautical, mining and petrochemical industry, masonry, pharmaceutical, food processing, material handling, construction and many others:

  1. Passenger Aircraft landing using reverse-thrusters. It is well recognised that a major contributor to plane-fatigue is due to landing, being more so than take-off and flying. Currently the reverse thruster is applied by stopping the engine, then reversing the blades, followed by re-thrusting the engine at high speed to overcome the front of engine-cowl high pressure. This invention will allow the front high-pressure to be equalised with the low-pressure at the rear of cowl, consequently decelerating the plane naturally without thrusting the engines. This is achievable as the blades-shaft can be free-wheeling in the reverse-rotation automatically, being free from the engine-shaft. Upon plane deceleration being attained, the blades are reversed again for normal thrust-position (as per current method), and the engine-shaft re-engage to the turbine-blades-shaft automatically and safely.

  2. High-tower construction cranes. It is well recognised that the fuel usage for the crane engine is equal or more for hook-downwards movements. At times it needs to go fast due to wind conditions etc. These downward movements are made by accelerating the crane-engines; thus more fuel usage, increased engines fatigue and wear and tear, and more emissions as a result. This invention will allow this downwards movements free of engine-thrusts, as the shaft can be made free-wheeling to opposite-direction/rotation without disengaging from the engine-shaft. Thus as a result the hook can be lowered fast and safe, and at the same time the clutch system operates as ‘breaks’ to allow the hook to stop its movement at any point, as the driver wishes.

  3. Air Compressor units and diesel engines. It is well recognised that both these items are well used and also recognised that each item recoils on shutting-down. Consequently major damage often occurs, increasing wear and tear, increasing maintenance costs, etc., with pin-shearing well accepted everywhere. This invention will allow recoils to occur naturally and automatically through its mechanical devices, without causing stress and strain, avoiding colliding/knocking impacts and torque shaft fatigue.

  4. Shipping liner anchors. It is well recognised that the lowering of an anchor is done using electrical energy. This invention will allow the anchor to lower with small energy, or without energy depending upon the arrangement, and be able to be lifted without a gear-switching, etc.

  5. Yacht sails/spinnaker release. It is well known that this task is massive due to gear-switchings at the same time as holding the large wind-energy at the crank and winch, etc. This invention allows the free-release of the spinnaker instantaneously without the need for holding winch and crank, and at the same time able to retract safely and quickly without gear-switching.

  6. Major valves in refineries and process industries. It is well accepted in the industry that the valves opening and closing requires massive electrical energy whether it is operated by pneumatic, hydraulic and electric motors.  In many applications fast opening or fast closing is required and this is achieved by using large pressures that consequently use large machineries, requiring more fuel and power. This invention will allow the opening and closing of valves to be made instantaneously using minimal energy, or without energy depending upon the arrangement.
