Abstract:
A metal rolling mill comprising:a case body;first drive means for actuating rotation of the metal rolling mill;a first roll system having a shaft having a first end, a second end, a roll disposed on said shaft and extending radially therefrom, and an axis of rotation; said first end being adapted to be operatively coupled to said drive means, said second end having a profile-shifted spiral bevel gear;a second roll system having a shaft having a first end, a second end, a roll disposed on said shaft and extending radially therefrom, an axis of rotation, and a profile-shifted spiral bevel gear disposed on said first and second ends; said profile-shifted spiral bevel gear on said first end being operatively engaged with said profile-shifted spiral bevel gear of the second end of the shaft of the first roll system such that said second roll system rotates synchronously with said first roll system;a third roll system having a shaft having a first end, a second end, a roll disposed on said shaft and extending radially therefrom, an axis of rotation, and a profile-shifted spiral bevel gear disposed on said first and second ends; said profile-shifted spiral bevel gear on said first end being operatively engaged with said profile-shifted spiral bevel gear disposed on the second end of the second roll system shaft such that said third roll system rotates synchronously with said second roll system;a fourth roll system having a shaft having a first end, a second end, a roll disposed on said shaft and extending radially therefrom, an axis of rotation, and a profile-shifted spiral bevel gear disposed on said first end, said profile-shifted spiral bevel gear on said first end being operatively engaged with said profile-shifted spiral bevel gear disposed on the second end of the third roll system shaft such that said fourth roll system rotates synchronously with said third roll system;a central metal processing groove formed by said four roll systems, wherein each of said rolls of said four roll systems extends radially from its respective shaft such that a circumferential edge of each respective roll forms an outer edge of said groove; andadjustment means disposed within said case body and being integrated into each of said roll systems for enabling size adjustment of said groove;wherein said first drive means and said four roll systems are disposed in one common plane.
