Automated device for locking and unlocking bearings

2:

• The installation of claim 1, wherein the movable retaining arm is housed inside the support arm.

3:

• The installation of claim 1, wherein an angular travel of the movable retaining arm during pivoting thereof is limited both by an angular position defined by the minimum gap and by an angular position corresponding to the unlocking position.

4:

• The installation of claim 1, wherein the movable retaining arm comprises an upper part adjacent to the roller bearing comprising an arc of a circle which does not cover at least an upper section of the roller bearing, so as to allow the roller to be removed when the movable retaining arm is pivoted laterally into the unlocking position.

5:

• The installation of claim 1, wherein the movable retaining arm has a geometry and a weight distributed such that the movable retaining arm is naturally in the unlocking position by gravity, and
• wherein the actuator is configured to press on the movable retaining arm so as to tilt the movable retaining arm from the unlocking position to the locking position.

6:

• The installation of claim 5, further comprising:
• a return spring configured to ensure full unlocking of the movable retaining arm by gravity.

7:

• The installation of claim 1, wherein the actuator comprises a single acting or double acting, pneumatic, hydraulic or electric cylinder.

8:

• The installation of claim 1, wherein a shim is provided on the movable retaining arm, the shim being adjusted adjustable to allow the movable retaining arm to abut against the support arm and to prevent contact, or to limit a contact force, between the movable retaining arm and the roller bearing.

9:

• The installation of claim 8, wherein the shim is attached to the movable retaining arm by a threaded rod passing through the shim so as to attach the shim in a bore provided in the movable retaining arm.

10:

• The installation of claim 7, wherein the actuator is remotely controlled.
