The model utility content
The present invention is limited to clutch moment of torque in the above-mentioned technology, structural relaxation, radial displacement is big, axial runout is big shortcoming, and a kind of split type cylinder free wheel device that can solve these shortcomings is provided, and this clutch noise is little, axially, circular runout is little.
Realize that technological scheme of the present invention is as follows:
The one wedge bearing clutch, this clutch has seat ring and outer ring, outer ring and seat ring are wholely set and form, be provided with inner ring in the outer ring, be provided with unidirectional limit stoper between outer ring and the inner ring, unidirectional limit stoper is the voussoir roller bearing, this voussoir roller bearing has retainer, voussoir roller and resetting means, retainer is provided with a groove and a rib, the voussoir roller is arranged on a groove and outer ring, in the raceway that forms between the inner ring and and the outer ring, inner ring contacts, resetting means is arranged between a rib and the voussoir roller, inner surface and inner ring outer surface one side circumferentially are provided with the cambered surface groove, this cambered surface groove is provided with deep groove ball bearing, and the voussoir roller bearing is arranged on a side of deep groove ball bearing.
Described resetting means is a Returnning spring, and this Returnning spring is arranged in the caulking groove of a rib.
Described voussoir roller bearing and deep groove ball bearing are set to the shared retainer of one, and retainer one side is provided with upper cover plate, and opposite side is provided with lower cover slip.
Described seat ring is provided with several pins, and it is on the circumference in the center of circle that pin is arranged on the inner ring center.
Described upper cover plate is provided with projection and the inserting pin that matches with caulking groove.
Split is provided with packing ring on the described pin.
The periphery of described outer ring inner headed face and inner ring is the high frequency hardening face.
The present invention adopts above scheme, the one wedge bearing clutch, this clutch has seat ring and outer ring, seat ring and outer ring are wholely set, such setting prevents that outer ring and seat ring from use forming wearing and tearing and cooperating not tight, be provided with inner ring in the outer ring, be provided with unidirectional limit stoper between outer ring and the inner ring, unidirectional limit stoper is the voussoir roller bearing, and is provided with deep groove ball bearing between outer ring and the inner ring, and the setting of this deep groove ball bearing has reduced the generation of noise, the internal surface of outer ring and inner ring outer surface one side circumferentially are provided with the cambered surface groove, this cambered surface groove is settled for the steel ball of deep groove ball bearing, has prevented beating of axial-radial, makes that the structure of clutch is more stable, increase working life, it is high frequency hardening that the periphery of inner ring and outer ring get inner headed face, can guarantee the pin positioning tolerance not because of heat treated factor produces the error that can not estimate, and useful benefit of the present invention is that moment of torsion is big, noise is low, radial displacement is little, and axial runout is little, has prolonged working life.
