Flywheel vacuum enclosure and adjustment system

A flywheel system comprising:

• an enclosure base having a bottom surface and one or more side walls coupled with the bottom surface;
• an enclosure lid having a top surface, the enclosure lid coupling with the enclosure base to create an enclosed space, the enclosed space containing a flywheel, the flywheel including a cylinder and one or more axles, the flywheel rotating about the one or more axles, a motor being mounted to the enclosure lid and coupled with the one or more axles, the motor changing a rotational velocity of the flywheel;
• one or more bearings coupling the one or more axles to the enclosure base and the enclosure lid, the one or more bearings holding the one or more axles at an axis of rotation;
• a nut bearing holder including a recess that holds a bottom bearing of the one or more bearings, the nut bearing holder including first threads that interact with second threads of the enclosure base, rotating the nut bearing holder in the second threads causing the nut bearing holder to move the bottom bearing in an axial direction;
• and
• a nut locking mechanism including one or more interfaces that interact with a corresponding structure on the nut bearing holder, the nut locking mechanism locking the nut bearing holder at one of a set of angles defined by the one or more interfaces.

A system comprising:

• an enclosure tub having a bottom surface and one or more side walls coupled with the bottom surface;
• an enclosure lid having a top surface, the enclosure lid coupling with the enclosure tub to create an enclosed space, the enclosed space containing a flywheel, the flywheel having one or more axles;
• one or more bearings coupling the one or more axles to the enclosure tub and the enclosure lid, the one or more bearings holding the one or more axles at an axis of rotation;
• and
• a positioning mechanism coupled with the enclosure tub, the positioning mechanism holding the one or more bearings, the positioning mechanism moving the flywheel vertically via the one or more bearings, the positioning mechanism including:
• a nut bearing holder including a recess that holds a bottom bearing of the one or more bearings, the nut bearing holder including first threads that interact with second threads of the enclosure tub, rotating the nut bearing holder in the second threads causing the nut bearing holder to move the bottom bearing in an axial direction;
• and
• a nut locking mechanism including one or more interfaces that interact with a corresponding structure on the nut bearing holder, the nut locking mechanism locking the nut bearing holder at one of a set of angles defined by the one or more interfaces.
