Spinning device

A spinning device comprising:

• a spinning box housing fixable on a base frame of a textile machine and supporting a rotor housing,
• a spinning rotor having a spinning cup on a rotor shaft supported in bearing nips of a support disk bearing for rotation of the rotor during spinning at a high number of revolutions in the rotor housing,
• a cover element for closing and opening the rotor housing,
• an arrangement for charging the rotor housing with a vacuum,
• a traveling belt acting tangentially on the rotor shaft,
• a rotor brake having a brake gear,
• a pivotable expander roller movable within a maximum pivot angle via a pressure lever system connected to the brake gear of the rotor brake between an operative position when the spinning box is closed, and an inoperative position wherein the expander roller is automatically lifted off the tangential belt and the rotor brake is applied to the rotor shaft, when the spinning box is opened,
• a brake and locking lever having a locking recess in contact with an arresting roller arranged on the cover element, and
• an arrangement in the pressure lever system for absorbing shock-like forces acting on the expander roller and for preventing the forces from being transmitted to the brake and locking lever, wherein the spinning box housing comprises a travel limitation means in a cross arm of the spinning box housing, limiting the maximum pivot angle of the expander roller.
