Abstract
A connection assembly for a sealed transfer cell, including a flange, a hinge, and a door connected to the flange by the hinge which can be moved between an open state and a closed state, the flange including central opening sealed by the door when this door is closed. The hinge includes a cylindrical rotary element securely connected to the door and two fixed bearings securely connected to the flange, the rotary element extending between the two bearings having two ends each engaged in a bearing, and this hinge contains an electric motor for opening and closing the door in a controlled manner.
Claims6
A connection assembly for a sealed transfer cell, the connection assembly including:
- a flange adapted to be fixed to an opening of a wall of the sealed transfer cell, and adapted to be coupled to a container flange,
- a hinge, and
- a door connected to the flange by the hinge, wherein the door is configured to be moved between an open state and a closed state,
- wherein the flange is configured to be fitted with a rotary lock located opposite the hinge, wherein the rotary lock is configured to lock the door in the closed state and to release the door into the open state,
- wherein the flange includes a central opening configured to be sealed by the door when the door is in the closed state,
- wherein the hinge includes a cylindrical rotary element securely attached to the door and two fixed bearings securely connected to the flange, the cylindrical rotary element extending between the two fixed bearings and having two ends each engaged in one bearing of the two fixed bearings,
- wherein the hinge comprises an electric motor having an output shaft and a gearbox interposed between the output shaft and the cylindrical rotary element of the hinge, the gearbox extending in the rotary element and being coupled to the output shaft and to the rotary element to drive the rotary element, and wherein the electric motor is configured to open and close the door in a controlled manner.
A method for mounting a connection assembly for a sealed transfer cell, the method including the steps of:
- fixing a base to a stator of a motor;
- fixing the base to a bottom of an upper bearing by screws;
- engaging a body of a gearbox on an output shaft of the motor to couple the body and the output shaft to one another,
- engaging a first ring about an upper end of a rotary element, the gearbox extending into the rotary element by being interposed between the output shaft and the rotary element, and the gearbox being coupled to the output shaft and to the rotary element to drive the rotary element;
- engaging the rotary element about the gearbox and engaging the upper end fitted with the ring in a tubular portion of the upper bearing;
- engaging a plate about a drive shaft and fixing the plate to a lower end of the rotary element by screws;
- fitting the lower end of the rotary element with a second ring and engaging the connection assembly in a tubular portion of a lower bearing;
- and
- fixing the bearings to a flange by screwing tabs.
