Abstract
A device for controlling the locking and unlocking operations of a gear wheel-rotary disc assembly comprises a ball for circulating screw having one end thereof coupled to a rotating coupling member. The screw is in turn rotatably engaged in a fixed ring-nut, which is housed in the bed of the device, to allow the screw to be axially driven, under the control of a driving motor. With respect to prior like devices, the inventive device allows the rotary disc to be driven quicker and more accurately from a locking position to an unlocking position thereof.
Claims17
A control device for controlling the locking and unlocking operations of a rotary disc with a gear wheel system, comprising;
- a ball recirculating screw-ring nut assembly including a ball recirculating screw rotatable and axially slidably engaged in a ring nut;
- a connection between said rotary disc and said ball recirculating screw such that said rotary disc is displaced axially together with said ball recirculating screw;
- and
- a device for driving said ball recirculating screw-ring nut assembly such that said ball recirculating screw is axially displaced between a first position in which said rotary disc is arranged for engaging a fixed gear wheel for blocking said rotary disc from rotation and a second position in which said rotary disc is arranged so that it is disengaged with the fixed gear wheel for permitting rotation of said rotary disc.
A control device for controlling the locking and unlocking operations of a rotary disc with a gear wheel system, said control device comprising rotary and axially displaceable means for axially displacing said disc (10) from a locking position to an unlocking position thereof at the end of the rotary movement of said disc, said rotary and axially displaceable means comprising a ball and recirculating screw (1)-ring nut (7) assembly, said screw (1) being rotatably and axially slidably arranged in said ring nut (7), and said screw (1) being provided with an end portion (3) engaging, in and axially slidably manner, with a rotating coupling member (2), in turn driven by a driving motor (4).
A control device for controlling the locking and unlocking operations of a rotary disc with a gear wheel system said control device comprising rotary and axially displaceable means for axially displacing said disc (10) from a locking position to an unlocking position thereof at the end of the rotary movement of said disc, said rotary and axially displaceable means comprising a ball and recirculating screw (1)-ring nut (7) assembly, said screw (1) being provided with a further end portion (8) axially rigid with said rotary disc (10).
