The split type cylindrical bearing clutch has the benefits of big torque, low noise, small radial displacement, small axial runout and prolonged service life.
Description
Technical field
The utility model belongs to clutch field, especially a kind of split 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.
The model utility content
Goal 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 split 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:
Split 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 split setting form, be provided with keyway on seat ring and the outer ring, seat ring is connected by the post key with the outer ring, 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 are provided with a groove and a rib, and cylindrical 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 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 cylindrical 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, split 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 split setting form, the setting of separate form, have one to damage the damage parts that in time to change wherein if guaranteed seat ring and outer ring, prevent the shortcoming that seat ring or inner ring have a damage just all will change, 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, 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.
