The situation of conjunction, cause its performance unstable, belt carcass circle and the relatively unrotatable situation of pulley easily occur；And for example, existing
Having in technology 2, engaging nail is simply fitted on pulley wheel shaft, and its respective outer side edges is still unstable, when belt carcass is pulled, but band
When torque caused by frictional force between core wheel and pulley is insufficient to allow pulley drive take-up pulley rotation, take-up pulley will be caused
Not take-up, and belt carcass wheel may produce relative rotation with pulley and disengage part belt carcass, then, easily from normal condition
Be directly changed the state of releasing, or from over-tension state be directly changed the state of releasing the problem of.
