The integrated cylindrical bearing clutch is provided with a race and an outer ring, an inner ring is arranged in the outer ring, a unidirectional limit device is arranged between the outer ring and the inner ring, the race is integrated with the outer ring which is a star wheel, the unidirectional limit device is a cylindrical roller bearing provided with a retainer, a cylindrical roller and a reset device, the retainer is provided with an inter-groove and an inter-ridge, the cylindrical roller is arranged in a raceway formed among the inter-groove, the outer ring and the inner ring to contact with the outer ring and the inner ring, the reset device is arranged between the inter-ridge and the roller, one side of the inner surface of the outer ring and one side of the outer surface of the inner ring are respectively provided with a cambered groove circumferentially, a deep groove ball bearing is arranged on the cambered grooves, and the cylindrical roller bearing is arranged on one side of the deep groove ball bearing. The integrated cylindrical bearing clutch has the advantages of having large torsion, low noise, small radial displacement and low axial jumping range and prolonging service life.
Description
Technical field
The utility model belongs to clutch field, especially a kind of integral type cylindrical bearing clutch that is used in the electric motor car.
Background technique
Clutch is divided into embedded clutch, engagement sleeve and automatic clutch, a kind of free wheel device is arranged in the automatic clutch, generally adopt free wheel device in the prior art in the electric motor car, it is mainly by star-wheel, outer shroud, ball, push rod and spring constitute, outer shroud is made a gear usually, sky is enclosed within on the star-wheel, in three breach of star-wheel, a roller respectively is housed, each ball is again by spring, push rod is pushed in the formed raceway of breach of outer shroud and star-wheel, such free wheel device moment of torsion is limited, structural relaxation, radial displacement is bigger, and in use axial runout is also big, the noise height, its performance and function are limited.
Summary of the invention
The utility model is limited at clutch moment of torque in the above-mentioned technology, structural relaxation, radial displacement is big, axial runout is big shortcoming, and a kind of integral type cylindrical bearing clutch that can solve these shortcomings is provided, and this clutch noise is little, axially, circular runout is little.
The realization the technical solution of the utility model is as follows:
Integral type cylindrical bearing clutch, it has seat ring and outer ring, be provided with inner ring in the outer ring, be provided with unidirectional limit stoper between outer ring and the inner ring, seat ring and outer ring are wholely set and form, the outer ring is a star-wheel, unidirectional limit stoper is a roller bearing, this roller bearing has retainer, cylindrical roller and resetting means, retainer is provided with a groove and a rib, cylindrical roller is arranged on a groove and outer ring, in the raceway that forms between the inner ring with the outer ring, inner ring contacts, resetting means is arranged between a rib and the roller, inner surface and inner ring outer surface one side circumferentially are provided with the cambered surface groove, and this cambered surface groove is provided with deep groove ball bearing, and roller bearing is arranged on a side of deep groove ball bearing.
Described resetting means is a reseting shrapnel, and this reseting shrapnel one end is fixed on the retainer, and the other end contacts with roller.
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.
Split is provided with packing ring on the described pin.
Adopted above-mentioned technology, integral type cylindrical bearing clutch, it has seat ring and outer ring, be provided with inner ring in the outer ring, be provided with unidirectional limit stoper between outer ring and the inner ring, seat ring and outer ring are wholely set and form, the setting of one form, guaranteed that connecting as one between seat ring and the outer ring is connected, prevent to beat because of wearing and tearing form between them, be provided with unidirectional limit stoper between this clutch outer and the inner ring, unidirectional limit stoper is a cylindrical roller, and be provided with deep groove ball bearing between outer ring and the inner ring, the setting of this deep groove ball bearing has reduced the generation of noise, being provided with for the steel ball of deep groove ball bearing of cambered surface groove is set on the inner ring settles, prevented beating of axial-radial, make 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 utility model is that moment of torsion is big, noise is low, radial displacement is little, and axial runout is little, has prolonged working life.
