Abstract
A one-way clutch includes a first rotator including an inner gear and configured to rotate on a first axis, a planetary gear configured to mesh with the inner gear and configured to rotate on a second axis that revolves around the first axis, a second rotator configured to rotate on the first axis and including a stopper configured to stop rotation of the planetary gear by engaging with the planetary gear, and an urging member configured to urge the planetary gear not to be brought in contact with the stopper in a state where the first rotator and the second rotator relatively rotate.
Claims12
A one-way clutch comprising:
- a first rotator comprising an inner gear and configured to rotate on a first axis;
- a planetary gear configured to mesh with the inner gear and configured to rotate on a second axis that revolves around the first axis;
- a second rotator configured to rotate on the first axis and comprising a stopper configured to stop rotation of the planetary gear by engaging with the planetary gear, wherein relative rotation of the first rotator and the second rotator is restricted in a state where the planetary gear and the stopper are engaged, and is permitted in a state where the planetary gear and the stopper are disengaged;
- and
- an urging member configured to urge the planetary gear not to be brought in contact with the stopper in a state where the first rotator and the second rotator relatively rotate.
A sheet conveyance apparatus comprising:
- a driving source;
- a conveyance member configured to be driven by the driving source and convey a sheet;
- and
- a one-way clutch configured to transmit driving force from the driving source to the conveyance member,
- the one-way clutch comprising:
- a first rotator comprising an inner gear and configured to rotate on a first axis;
- a planetary gear configured to mesh with the inner gear and configured to rotate on a second axis that revolves around the first axis;
- a second rotator configured to rotate on the first axis and comprising a stopper configured to stop rotation of the planetary gear by engaging with the planetary gear, wherein one of the first and second rotators is coupled to the driving source and the other of the first and second rotators is coupled to the conveyance member, and wherein relative rotation of the first rotator and the second rotator is restricted in a state where the planetary gear and the stopper are engaged, and is permitted in a state where the planetary gear and the stopper are disengaged;
- and
- an urging member configured to urge the planetary gear not to be brought in contact with the stopper in a state where the first rotator and the second rotator relatively rotate.
