摘要

Automatic compensating device of the tension exerted by the band saw to the steering wheel and bearings of the lower shaft of the machines saw mural murals od e columns, characterized in that it is determined that the traction of the lower flywheel shaft is carried out so that the draft of the belts are directed downwards in the opposite direction to the belt shot, for which purpose the flywheel shaft is mounted rotatable on bearings or bearings, in a tube that forms a body with an enclosing box that covers and encloses the entire mechanism, the which is open in front and sealed by a removable cap, only the steering wheel emerges, this tube being closed at the rear by a cover and sealed in front by a retainer in order to act as a box of grease, coupling solidaria with the flywheel shaft, a grooved pulley that is struck by a trapezoidal belt drive from a grooved pulley attached to the shaft of the electric drive motor, located at right below the previous one, with which the shot is made downwards, the upper pulley being hollow and flanged to form an internal channel destined to retain the grease that could be poured out of the tube.
