Abstract
Belt traps for a belt drive system include a bracket configured to receive at least a portion of a pulley to capture a failed drive belt between the bracket and a pulley. The pulley may be a tensioner pulley and may be biased in a direction towards the bracket. The bracket may include a relief portion configured to receive at least a portion of the pulley. The relief portion may include an opening or a recess that is sized and shaped to receive at least a portion of the pulley.
Claims20
A belt trap comprising:
- a movable pulley configured to carry an endless drive belt, the pulley rotatable about an axis of rotation;
- and
- a bracket disposed adjacent to the pulley and defining a relief portion sized and shaped to receive at least a portion of the pulley, the pulley movable from a first position corresponding to an operational configuration to a second position corresponding to an arresting configuration in which a portion of the pulley is received into the relief portion of the bracket.
A belt drive system comprising:
- an endless drive belt moveable along a circuitous route;
- a drive pulley that drives the endless drive belt along the circuitous route;
- and
- a belt trap comprising:
- a tensioner pulley biased in a first direction by a biasing force to introduce tension in the endless drive belt and movable from a first position to a second position, the tensioner pulley comprising:
- a peripheral edge;
- and
- a groove formed in the peripheral edge that receives a portion of the endless drive belt, the tensioner pulley rotatable in a first rotational direction about an axis;
- and
- a bracket disposed adjacent to the tensioner pulley, the bracket comprising a relief portion that receives a portion of the peripheral edge of the tensioner pulley when the endless drive belt fails so as to trap the failed endless drive belt between the tensioner pulley and the bracket.
