TWO-POSITION ELECTROMAGNETIC CLUTCH Russian patent published in 2024 - IPC F16D27/02 F16D27/01 F16H3/44 

FIELD: electricity.

SUBSTANCE: invention relates to electromagnetic couplings. Two-position electromagnetic clutch includes a drive shaft, a fixed core with a built-in coil, a movable core, a movable permanent magnet, a sun gear, an epicycle, satellites, a carrier, an anchor, and rolling elements. Drive shaft transmits rotary motion and has a free end. Movable core is made in the form of a magnetic conductor. Movable permanent magnet is fixed on the movable core and has magnetic flux. Sun gear is located on the free end of the shaft coaxially with the axis. Satellites are engaged with sun gear and epicycle. Carrier has pins retaining the satellites and not preventing their rotation and is made coaxially with the axis of the drive shaft with the possibility of rotation relative to it. Anchor is rigidly fixed on the carrier, which is an output link at the same time. Epicycle is fixed on the inner diameter of the movable core. Additionally, rolling elements have common separator and are located in recesses made on cores and anchor.

EFFECT: enabling expansion of applications of the coupling, including in the composition of robotic products, due to reduction of weight and dimensions at the same transmitted moment, reduction of power consumption, increased reliability, and provision of rotation transfer without mutual turning of parts.
