Abstract
A clutch is provided that includes an inner race and an outer race that moves relative to the inner race. A pedestal is also provided and the position of the pedestal is fixed with respect to at least one of the inner race or the outer race. A bearing block is also included that engages the pedestal. In some versions of the clutch the bearing block may be made out of plastic or bronze.
Claims28
A clutch, comprising:
- an inner race;
- an outer race displaceable relative to said inner race;
- a first pedestal, extending from at least one of said inner and outer race;
- a first bearing block engaging said first pedestal, said first bearing block and said first pedestal extending between the inner and outer races;
- a first spring engaging said first bearing block and said first pedestal at the same time;
- a roller engaging said first spring, wherein said first spring directly faces said bearing block and said roller and is located in an arc length direction between said first bearing block and said roller;
- a second pedestal, extending from at least one of said inner and outer race;
- a second bearing block engaging said second pedestal, wherein said roller directly faces said first spring and said second bearing block and is located in an arc length direction between said first spring and said second bearing block;
- and
- a second spring engaging said second bearing block.
