Abstract:
A resistance unit for an exercise device, comprising:a support member; a housing defining an interior and including structure engageable with the support member; a shaft having a first portion extending into the interior of the housing and a second portion located exteriorly of the housing, wherein the shaft is interconnected in the exercise device so as to rotate in response to application of an external force by a person performing an exercise; a resistance mechanism interconnected with the first portion of the shaft and located within the interior of the housing for resisting the external force; a series of bearing members for rotatably supporting the shaft, comprising a pair of bearing members engaged with the support member at spaced locations and through which the shaft extends, and a third bearing member engaged with the housing; and an inertial member interconnected with the second portion of the shaft and rotatable therewith, wherein the inertial member includes a blade arrangement which is operable to move air toward the housing upon rotation of the inertial member by rotation of the shaft to dissipate heat from the housing.
