Abstract

A method of insuring the proper vertical position of a generally horizontal endless type belt 10 is shown, which utilizes crowned pulleys 12 and A method of insuring the proper vertical position of a generally horizontal endless type belt 10 is shown, which utilizes crowned pulleys 12 and 14 which are free to move vertically on a drive shaft 16 and an idler shaft 18, respectively. Guide rolls 20 engage the lower edge of the belt, and the drive pulley 12 is driven by a motor 22 through the medium of a drive tang 24 which projects through an opening in the pulley 12 with a sliding fit.

Belt Positioning with Floating Pulleys

A method of insuring the proper vertical position of a generally horizontal endless type belt 10 is shown, which utilizes crowned pulleys 12 and A method of insuring the proper vertical position of a generally horizontal endless type belt 10 is shown, which utilizes crowned pulleys 12 and 14 which are free to move vertically on a drive shaft 16 and an idler shaft 18, respectively. Guide rolls 20 engage the lower edge of the belt, and the drive pulley 12 is driven by a motor 22 through the medium of a drive tang 24 which projects through an opening in the pulley 12 with a sliding fit.

The position of the high spot on the crowned pulleys is such that it will allow the pulleys to float at all times with the edge of the belt against the guide rolls, so as to compensate for differences which occur in flat belts affecting the location of the actual centerline of the belt.
