Abstract
Described herein are gears having magnetic properties with strategic positioning of the magnetic portion(s) of the gears. This allows for multiple gears to be used in a gearing system without the need for the gears to touch thereby eliminating the need for lubricants and limiting wear on the gears in the system while also reducing heat generated by the system and the need for additional cooling systems.
Claims17
A magnetic gear comprising:
- a first plurality of magnets including first magnets and second magnets;
- a magnet retaining structure having a body with a periphery and more than one vertices,
- wherein the magnet retaining structure is configured to secure a position of each of the plurality of magnets relative to the magnet retaining structure,
- wherein one first magnet of the first magnets is positioned between two respective adjacent vertices of the body,
- wherein one second magnet of the second magnets is located at each vertex of the two respective adjacent vertices, and
- wherein the one first magnet, located between the second magnets at the two respective adjacent vertices is biased toward one vertex of the two respective adjacent vertices.

A magnetic gear comprising:
- a plurality of magnets;
- a magnet retaining structure configured to secure a position of each of the plurality of magnets between a first body and a second body,
- wherein the first body and the second body have a substantially identical periphery and are configured to be secured to one another,
- wherein the plurality of magnets are disposed along a periphery of the first body with a polarity of each magnet being of an opposing polarity in relation to the magnet on either side of the magnet,
- wherein a magnet of the plurality of magnets is positioned at each vertex of the periphery and one magnet of the plurality of magnets is positioned between the magnet located at each vertex, and
- wherein the one magnet located between the magnet located at each vertex splits a distance between two vertices in a 40:60 split.

- wherein one second magnet of the second magnets is located at each vertex of the two respective adjacent vertices, and
- wherein the one first magnet, located between the second magnets at the two respective adjacent vertices is biased toward one vertex of the two respective adjacent vertices;
- and
- a second magnetic gear comprising:
- a second plurality of magnets including third magnets and fourth magnets;
- a magnet retaining structure having a body with a periphery and more than one vertices,
- wherein the magnet retaining structure is configured to secure a position of each of the plurality of magnets relative to the magnet retaining structure,
- wherein one third magnet of the third magnets is positioned between two respective adjacent vertices of the body,
- wherein one fourth magnet of the fourth magnets is located at each vertex of the two respective adjacent vertices, and
- wherein the one third magnet, located between the fourth magnets located at the two respective adjacent vertices is biased toward one vertex of the two respective adjacent vertices.
