Abstract
A torque limiter includes a driving bushing, a clutch spring wound around an outer circumference of the driving bushing, and a housing receiving a driving force via the clutch spring. The housing includes a first catch portion engaged with a first end portion of the clutch spring, and a second catch portion engaged with a second end portion of the clutch spring. The second catch portion is movable with respect to the first catch portion to change an angle between the first and second end portions of the clutch spring.
Claims16
A torque limiter comprising:
- a driving bushing;
- a clutch spring wound around an outer circumference of the driving bushing;
- and
- a housing to receive a driving force via the clutch spring,
- wherein the housing comprises:
- a mounting part including an opening defining a plurality of predetermined positions;
- a first catch portion engaged with a first end portion of the clutch spring;
- a second catch portion engaged with a second end portion of the clutch spring, the second catch portion being moveable between the plurality of predetermined positions with respect to the first catch portion to change an angle between the first and second end portions, wherein each of the plurality of predetermined positions corresponds to a different angle between the first and second end portions;
- and
- a locking portion including an adjustment arm extending from the second catch portion into the opening to lock the second catch portion in any one of the plurality of predetermined positions to maintain the changed angle between the first and second end portions.

A torque limiter comprising:
- a driving bushing;
- a clutch spring wound around an outer circumference of the driving bushing;
- and
- a housing receiving a driving force via the clutch spring, the housing comprising a mounting part including an opening defining a plurality of predetermined positions, a first housing, and a second housing coupled to be movable between the plurality of predetermined positions with respect to the first housing, and a locking portion including an adjustment arm extending into the opening to lock the second housing in any one of the plurality of predetermined positions,
- wherein the first housing comprises a first catch portion engaged with a first end portion of the clutch spring, and the second housing comprises a second catch portion engaged with a second end portion of the clutch spring, such that an angle between the first and second end portions of the clutch spring is changed when the first and second housings are moved between the plurality of predetermined positions with respect to each other.

A torque limiter comprising:
- a drive member to receive torque about a rotational axis thereof;
- a clutch member frictionally coupled to the drive member by an amount of friction proportional to a spread distance between a first end portion and a second end portion thereof;
- and
- a housing having a mounting part including an opening defining a plurality of predetermined positions, the housing being coupled to the clutch member through a first catch portion and a second catch portion thereof respectively engaging the first end portion and the second end portion of the clutch member, the first catch portion and the second catch portion being displaceable respective one another between the plurality of predetermined positions to establish a selected spread distance between the first end portion and the second end portion of the clutch member and subsequently locked in a relative position respective one another by a locking portion including an adjustment arm extending from the second catch portion into the opening to maintain the selected spread distance between the first and second end portions.

A torque limiter comprising:
- a cylindrical drive member to receive torque about a rotational axis thereof;
- a clutch member frictionally coupled to an outer periphery of the drive member by an amount of friction proportional to a spread distance between a first end portion and a second end portion thereof;
- and
- a cylindrical housing having a longitudinal dimension parallel to the rotational axis and a radial dimension, the housing having a mounting part including an opening defining a plurality of predetermined positions and being coupled to the clutch member through a first catch portion and a second catch portion thereof respectively engaging the first end portion and the second end portion of the clutch member, the first catch portion and the second catch portion being displaceable respective one another between the plurality of predetermined positions to establish a selected spread distance between the first end portion and the second end portion of the clutch member and subsequently locked in a relative position respective one another by a locking portion including an adjustment arm extending from the second catch portion into the opening to maintain the selected spread distance between the first and second end portions.
