The present invention relates to the field of a gear system, and more particularly, to a magnetic gear system for the transfer of power.
The power transmission is mechanical in most machines, and it is commonly achieved through gear transmissions. Mechanical gear transmissions have a high torque density, but friction occurs in them, which is often the cause of gear failure. Also, noise, heat and vibration are present, so the reliability and longevity of these gears is reduced. Gears and gear systems can be used in many different types of mechanical devices and for many different purposes. Gears are used in vehicle transmissions, wind turbines, elevators, helicopters and the like.
Also, in the traditional energy-generating apparatus, gear systems are used where the motor generates kinetic energy through rotation. Motors and generators generate kinetic energy and electric energy, respectively, and use permanent magnets to generate electricity.
Conventionally, the renewable electric power which is generated is based on the well-known Faraday’s law of electromagnetic induction by using permanent magnets for generating electricity.
In order to produce electricity, there is a need of high powered magnets like neodymium Magnets which have high magnetic strength, a DC generator for converting the mechanical motion of the shaft to electric energy, a Spur gear to transfer mechanical motion as well as control speed, power and torque and a battery to store the electric energy.
Conventionally, two round gears of different sizes can be used to alter the speed and direction of rotational force. This includes changing the direction of the rotation or changing the rotational axis from vertical to horizontal and the like. Gears can also be used to change torque.
The biggest problem with conventional gears and gear systems is the loss of energy due to friction caused by the gears mechanically connecting, mating or engaging. Conventional gears and gear systems also experience significant stresses due to their interaction with other gears which often leads to failure of the gears and gear systems. In order to overcome these issues, several magnetic gear systems have been created. These gear systems are contactless and frictionless. Therefore, the magnetic gears and gear systems lose less energy and experience less stress than traditional gears and gear systems.
Conventional motors typically rely on a defined input power source to produce an output; may it be a mechanical or electrical output. Such motors typically rely on magnetic generators to either convert an electrical input to a mechanical output, or to convert a mechanical input to an electrical output. Although these motors may include numerous magnetic sources, and rely on the electromotive force to operate, few utilize these magnetic sources to actually provide, or enhance the input power supplied to the motor.
In addition, motors that rely on magnets for an input force will wear down and stop operating over time due to friction forces existing between component parts and magnetic devices. Such devices may operate for a short time but cannot continuously operate over an extended period of time. With the development of technology, one object of the present invention is to develop other ways of power and torque transmissions, whereby the noise, vibration, maintenance costs, and the like would be lower. One of those ways is the use of magnets in power transmission.
Despite these numerous systems, there is a need for a magnetic gear system that has a magnet arrangement that maximizes the use of the magnetic fields and potential energy of the magnets to aid the transfer of energy through the magnetic gear system.
Accordingly, there is a need in the art for a motor that can generate torque and produce energy that utilizes magnetic devices as an input force, and may also operate for a longer time.
The present invention overcomes certain limitations of conventional gear systems by providing a unique arrangement of cylinders that are rotatable with respect to each other to modify a radial air gap between the cylinders. The intensity of a magnetic field in the air gap varies as the magnetic poles are moved into and out of alignment with each other. This arrangement provides mounting and demounting of gears with greater ease than before, while also providing a cylinder construction that has numerous advantages.
One main object of the present invention is to overcome the disadvantages of prior art. Another object of the present invention is to provide for a more efficient power transmission system. Yet another object of the present invention is to provide a magnetic gear system that transfers power in a frictionless manner and without mechanical connections between the gears, without being dependent on expensive or complex components. Yet another object of the present invention is to provide a frictionless gear system for electricity generation. Embodiments of the present invention provide for devices and methods and disclosed herein and as defined in the annexed claims which provide for improved power transmission gear systems and electrical generation systems.
It is one prospect of the present invention to provide one or more novel devices of simple but effective construction which may be applied to many appliances which use gear systems.
