Abstract
Abstract The present invention relates to an assembly cage for the jamming and/or rolling devices of a free-wheel or a rotary bearing, which comprises two coaxial tracks arranged so as to cooperate with said devices, said cage being adapted to extend between said tracks and having a generally cylindrical form with a series of windows in which said devices are housed, said assembly cage further comprising two annular end-plates assembled together by bracing means which serve to define said circular series of windows intended to receive said devices, said bracing means having terminal portions including means for their assembly on said end-plates, said assembly means comprising at least one dove-tail intended to be engaged in an opening formed in each said end-plate, said opening being larger than the section of said terminal portion and the fixing together of said assembly being effected by radial deformation of said end-plates at the level of said openings, on at least one side of said dove-tails.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
212 words
An assembly cage for the jamming devices of a one-way coupling or free-wheel device, comprising two coaxial tracks, a said cage extending between said tracks and having a generally cylindrical form with a series of windows in which said devices are housed, said assembly cage further comprising two annular end-plates, bracing means which interconnect said end-plates and which define said circular series of windows, said bracing means having terminal portions including means for their assembly on said end-plates, the last-named means comprising at least one dove-tail engaged in an opening formed in each said plate, said opening being larger than the section of said terminal portion, said end-plates being radially deformed at the level of said openings, on at least one side of said dove-tails, thereby to fix together said assembly, said bracing means comprising a member in the form of a flat ladder comprising upright members and rungs, and rolled into a cylindrical shape, said ladder having lateral projections which constitute said assembly means, said projections being engaged in slots formed in said end-plates, in which they are held fixed, each said projection having the form of a trapezium with a large external base smaller than the said slot so as to leave a space when the projection is engaged therein.

An assembly cage for the jamming devices of a one-way coupling or free-wheel device, comprising two coaxial tracks, a said cage extending between said tracks and having a generally cylindrical form with a series of windows in which said devices are housed, said assembly cage further comprising two annular end-plates, bracing means which interconnect said end-plates and which define said circular series of windows, said bracing means having terminal portions including means for their assembly on said end-plates, the last-named means comprising at least one dove-tail engaged in an opening formed in each said plate, said opening being larger than the section of said terminal portion, said end-plates being radially deformed at the level of said openings, on at least one side of said dove-tails, thereby to fix together said assembly, said bracing means comprising a member in the form of a flat ladder comprising upright members and rungs, and rolled into a cylindrical shape, said ladder having lateral projections which constitute said assembly means, said projections being engaged in slots formed in said end-plates, in which they are held fixed, each said projection having the form of a trapezium with a large external base smaller than the said slot so as to leave a space when the projection is engaged therein.
Claim 3
Dependent Claim
25 words
An assembly cage as claimed in claim 1 in which the interior contour of said end-plate is deformed in the direction of the external contour.
Claim 4
Dependent Claim
108 words
An assembly cage as claimed in claim 1 in which the walls of said slot have the form of a rectangular parallelepiped, and in which said trapezium has the form of a rectanguLar trapezium with a large external base having a straight face so as to come into application in flat contact with one of the walls of said slot, and with an oblique face so as to give the space receiving the material of said end-plate the shape of a wedge suitable especially for the axial retention of the projection in said slot when once the end-plate has been deformed so as to penetrate into said space.
Claim 5
Dependent Claim
209 words
An assembly cage for the rolling members of a roller or like bearing, comprising two coaxial tracks, a said cage extending between said tracks and having a generally cylindrical form with a series of windows in which said members are housed, said assembly cage further comprising two annular end-plates, bracing means which interconnect said end-plates and which define the circular series of windows, said bracing means having terminal portions including means for their assembly on said end-plates, the last-named means comprising a dove-tail engaged in an opening formed in each said end-plate, said opening being larger than the section of said terminal portion, said end-plates being radially deformed at the level of said openings, on at least one side of said dove-tails, thereby to fix together said assembly, said bracing means comprising a member in the form of a flat ladder comprising upright members and rungs, and rolled into a cylindrical shape, said ladder having lateral projections which constitute said assembly means, said projections being engaged in slots formed in said end-plates, in which they are held fixed, each said projection having the form of a trapezium with a large external base smaller than the said slot so as to leave a space when the projection is engaged therein.
Claim 6
Dependent Claim
209 words
An assembly cage for the rolling members of a roller or like bearing, comprising two coaxial tracks, a said cage extending between said tracks and having a generally cylindrical form with a series of windows in which said members are housed, said assembly cage further comprising two annular end-plates, bracing means which interconnect said end-plates and which define the circular series of windows, said bracing means having terminal portions including means for their assembly on said end-plates, the last-named means comprising a dove-tail engaged in an opening formed in each said end-plate, said opening being larger than the section of said terminal portion, said end-plates being radially deformed at the level of said openings, on at least one side of said dove-tails, thereby to fix together said assembly, said bracing means comprising a member in the form of a flat ladder comprising upright members and rungs, and rolled into a cylindrical shape, said ladder having lateral projections which constitute said assembly means, said projections being engaged in slots formed in said end-plates, in which they are held fixed, each said projection having the form of a trapezium with a large external base smaller than the said slot so as to leave a space when the projection is engaged therein.
