Abstract
A two roller machine, and more particularly a roll type crusher, which comprises two oppositely driven rollers rotatably seated in a housing and having gearings connected to the drive journals of the rollers, the gearings being flexibly connected to one another by torque supports for absorbing the reaction moments and said torque supports being formed as two-armed lever plates and being rigidly joined to the gearing. A considerable simplification of the torque support is inventively achieved in that levers are rotationally arranged at the outer, opposite ends of the lever plates formed as torque supports, said levers being connected to one another by a toggle link.
