Abstract
A magnetic load applying device includes a plate secured on a spindle, and a rotating disc rotatably secured on the spindle and having a peripheral fence engaged on the plate. One or more arms each supports one or more magnets and each has one end rotatably secured to the plate for moving the magnets toward and away from the peripheral fence of the rotating disc and for adjusting the brake torque of the magnets applied onto the rotating disc. One or more springs may bias the arms and the magnets toward the peripheral fence of the rotating disc.
Claims5
A magnetic load applying device comprising:
- a spindle,
- a plate secured on said spindle, said plate including at least one stud extended therefrom,
- a rotating disc rotatably secured on said spindle and including a peripheral portion,
- at least one arm including a first end rotatably secured to said plate at a pivot pin, and including a second end,
- at least one magnet secured on said at least one arm, and
- means for rotating said at least one arm about said pivot pin to move and to adjust said at least one magnet relative to said peripheral portion of said rotating disc and to adjust a brake torque applied onto said rotating disc, said rotating means including a follower rotatable secured onto said spindle and coupled to said second end of said at least one arm for rotating said at least one arm about said pivot pin when said follower is rotated about said spindle, said follower including at least one extension extended radially outward therefrom and coupled to said second end of said at least one arm for rotating said at least one arm about said pivot pin, said at least one extension including a groove formed therein for receiving said at least one stud and for limiting a relative rotational movement between said follower and said plate.
