The utility model provides a kind of free wheel device retainer, comprise the ring frame that two ends are coaxial, ring equidistantly, axially is provided with connection strap in week between the ring frame, connection strap becomes uniform grid with the surface segmentation of retainer, form mouse cage type structure, grid is embedded in the roller that free wheel device uses, one end face butt of the outer surface of roller and rectangular Returnning spring, the other end of rectangular Returnning spring and the connection strap of retainer connect, and the wall of retainer connection strap is provided with the constraint mechanism that moves at the rectangular Returnning spring.
Preferably, the wall of retainer connection strap is provided with and the axially interior suitable rectangular lug of cross section of described Returnning spring; Returnning spring is packed into behind the retainer, and lug axially inserts Returnning spring along Returnning spring, and the internal surface of the side surface of lug and rectangular Returnning spring fits, and forms the constraint to the radial translation and the axial rotation of Returnning spring.
Preferably, retainer connection strap wall is provided with and suitable rectangular counterbore or the annular groove of the axial external frame of Returnning spring; Returnning spring is packed into behind the retainer, and Returnning spring embeds in counterbore or the annular groove vertically, forms the constraint to the radial translation and the axial rotation of Returnning spring.
Preferably, the retainer connection strap is the rectangular column structure.
Preferably, the retainer connection strap directly towards the one side of roller be provided with roller axle to the circular groove consistent, that profile is adaptive, roller circular groove with the inside and outside circle lock state of clutch the time is used for roller is supported and retrains.
Preferably, the outer surface of retainer connection strap radially extends lug, in the fixed groove of lug embeddeding clutch outer ring, makes between retainer and the clutch outer to be fastenedly connected.
Compared with prior art, the utlity model has following beneficial effect:
By the retainer at the rectangular Returnning spring is set, can realize being connected more reliably between Returnning spring and the retainer, make Returnning spring can support the roller of free wheel device more reliably, avoid roller to use cylindrical Returnning spring conventional more than two simultaneously, reduce the installation difficulty of Returnning spring, improve work efficiency.
