Abstract
A roll stand with two rolls forming a gap has each roll connected to a separate drive motor by a drive train having a spindle with a toothed coupling to the drive roll. One of the drive trains includes two components connected to each other by a flexible coupling permitting a large angular shaft displacement with one of the components connected by a second flexible coupling to the drive motor and the other drive train includes the drive spindle being formed by a single component coupled to the drive shaft of the motor by a toothed coupling.
Claims13
A roll stand comprising two rolls with axes forming a roll gap, which rolls are driven by their separate drive motors via drive spindles, with each roll having a separate drive train comprising a toothed coupling, the improvements comprising a first drive train of the separate drive trains being formed by a drive spindle with first and second components connected with each other by a flexible coupling permitting large angular shaft displacements and the first component being connected with the drive shaft of the drive motor by a second flexible coupling and a second drive train of the separate drive trains having a drive spindle in the form of a single component toothed spindle extending from the toothed coupling to a second coupling arranged on the drive shaft of the motor and said second coupling being a toothed coupling permitting angular displacement, the second component of the first drive train being substantially shorter than the single component, and the axes of the first and second components diverging away from the axis of the single component.
A roll stand comprising two rolls with axes forming a roll gap, which rolls are driven by their separate drive motors via drive spindles, with each roll having a separate drive train comprising a toothed coupling, the improvements comprising a first drive train of the separate drive trains being formed by a drive spindle with two components connected with each other by a flexible coupling permitting large angular shaft displacements and one of said two components being connected with the drive shaft of the drive motor by a second flexible coupling and a second drive train of the separate drive trains having a drive spindle in the form of a single component toothed spindle extending from the toothed coupling to a second coupling arranged on the drive shaft of the motor and said second coupling being a toothed coupling permitting angular displacement, the component of the toothed coupling of the toothed spindle of the first drive train being supported on a foundation by a compensation device serving to maintain a predetermined angular position, which compensation device is formed by a parallel guide constructed as a system of levers.
A roll stand comprising two rolls with axes forming a roll gap, which rolls are driven by their separate drive motors via drive spindles, with each roll having a separate drive train comprising a toothed coupling, the improvements comprising a first drive train of the separate drive trains being formed by a drive spindle with two components connected with each other by a flexible coupling permitting large angular shaft displacements and one of said two components being connected with the drive shaft of the drive motor by a second flexible coupling and a second drive train of the separate drive trains having a drive spindle in the form of a single component toothed spindle extending from the toothed coupling to a second coupling arranged on the drive shaft of the motor and said second coupling being a toothed coupling permitting angular displacement, the toothed spindles being supported relative to a foundation via a pivot bearing by means of a lateral guide spindle balancing means.
