A system for measuring deformations of an area of a structural element, includes at least one gauge including a rigid substrate on the upper surface of which is arranged at least one pattern of a material capable of being deformed and delivering a signal representative of the deformations the substrate is arranged to transmit, to the pattern, the deformations of the area when the lower surface of the substrate is attached to the area. The system includes a deformable element and a device for compression of the element on the upper surface of the substrate so that the substrate can be moved by the deformations of the area. The system also includes an arrangement for attachment of the compression device on the structural element, in which the attachment arrangement is intended to ensure that the substrate is held on the area by the deformable element, which is compressed on the upper surface of the substrate.

A system for measuring deformations of an area of a structural element, which system includes at least one gauge including a rigid substrate on an upper surface of which is arranged at least one pattern of a material capable of being deformed and delivering a signal representative of said deformations, said substrate being arranged to transmit to the at least one pattern the deformations of the area when a lower surface of said substrate is attached to said area, a deformable element and a device for compression of said deformable element on the upper surface of the substrate so that said substrate can be moved by the deformations of the area, and means for attaching said compression device on the structural element, and said attaching means being intended to ensure that said substrate is held on the area by the deformable element, which is compressed on the upper surface of the substrate.
A roller bearing including a stationary member, a rotary member and at least one row of rolling bodies arranged between said stationary and rotary members so as to enable their relative rotation, said stationary member including at least one area that can be resiliently deformed by forces induced by a passage of the rolling bodies when the rotary member rotates, and at least one system for measuring deformations of said at least one area of a structural element, which system includes at least one gauge including a rigid substrate on an upper surface of which is arranged at least one pattern of a material capable of being deformed and delivering a signal representative of said deformations, said substrate being arranged to transmit to the at least one pattern the deformations of the area when a lower surface of said substrate is attached to said area, a deformable element and a device for compression of said deformable element on the upper surface of the substrate so that said substrate can be moved by the deformations of the area, and means for attaching said compression device on the structural element, and said attaching means being intended to ensure that said substrate is held on the area by the deformable element, which is compressed on the upper surface of the substrate and the lower surface of the substrate is attached on said at least one area and the attaching means ensure that said substrate is held on the at least one area by means of the deformable element, which is compressed on the upper surface of the substrate so that said substrate is moved by the deformations of the at least one area.
The roller bearing according to claim 12, further including two rows of rolling bodies, and the measurement system including two patterns of material arranged in a vicinity of a radial plane containing a row, and two deformable elements that are compressed on the patterns.
