Abstract

The utility model discloses a separated rolling bearing. Axial holes are arranged on rolling bodies positioned between an inner ring and an outer ring. A retainer ring is provided with through holes used for riveting. Rivets can pass through the axial holes and the through holes for riveting, can also pass out of the rolling bodies and isolated bodies and can pass through the through hole of the retainer ring to implement riveting. Each rolling body can be designed as a hollow body, and each isolated body can be designed as a solid body. The retainer ring is provided with positioning grooves of the isolated bodies. The center of each isolated body and the center of each rolling body are positioned in the same circumference. Accordingly, the isolated bodies and the rolling bodies mutually form rolling friction at the time of running. When an individual rolling body bears impact force, the impact force can be transferred to other rolling bodies. The stress is uniform and the service life of the rolling bearing can be extended.

Description

A kind of isolation rolling bearing

The utility model relates to a kind of isolation rolling bearing.

Traditional rolling bearing is made up of inner ring, outer ring, rolling element and retainer, and rolling element and is loaded in the retainer between inner ring, outer ring, so that the even bearing load of each rolling element; But under the impact load effect of different direction, each rolling element discontinuity makes the retainer bending easily, even fracture, and damage of bearings, this situation is comparatively common on farm machinery.

The purpose of this utility model is to design a kind of rolling bearing that comprises inner ring, outer ring, rolling element, back-up ring, slider and rivet for overcoming above-mentioned deficiency; Each rolling element is stressed more even, has improved the life-span of rolling bearing.

The utility model content, be provided with axial bore on the rolling element between inner ring and the outer ring, back-up ring is provided with the through hole of riveted joint usefulness, and rivet is by the hole and the through hole riveted joint of described axle, back-up ring is provided with the locating slot of slider, being centered close on the same circumference of the center of rolling element and slider.

For ball bearing, also can on slider, establish axial bore, rivet is by the riveted joint of the through hole on this axial bore and the back-up ring, and that rolling element can be designed to is solid; Also can make rivet outside rolling element and slider and the through hole that passes back-up ring rivet, rolling element, slider all can be designed to solid.

The utlity model has following advantage:

(1) owing to is provided with slider, rolling element, slider between adjacent two rolling elements by back-up ring and rivet location, closely be distributed on the same circumference, so when a rolling element is hit power, can pass to this impact force on other rolling element, stressed more even, be rolling friction between rolling element and slider, surface friction drag is little, can improve the life-span of rolling bearing.

(2) rolling element or the slider with axial bore can improve the shock proof ability of rolling bearing.

Description of drawings:

Fig. 1 is the utility model structural representation;

The structural representation that Fig. 2 uses on conical bearing for the utility model;

Fig. 3 is the utility model application structure schematic representation on cylindrical bearing;

Fig. 4 is the utility model application structure schematic representation on ball bearing.

Further specify the utility model embodiment below in conjunction with accompanying drawing.

Embodiment 1, see Fig. 2, between outer ring 1 and inner ring 2, rolling element 5 is housed, this rolling element is conical, be provided with slider 6 between adjacent two rolling elements of cone, slider is cylindrical (or cone), and slider is loaded in the locating slot of left and right baffle plate, and baffle plate is the shape shape part that is loaded between the inside and outside circle; Rolling element is provided with axial bore, the rolling element two ends are respectively equipped with left and right baffle plate 3,4, rivet 7 is riveted the three by the axial bore of left and right baffle plate and rolling element, make rolling element center and slider be centered close on the same circumference and contact with each other, improved the ability that rolling bearing withstands shocks.

Embodiment 2, see Fig. 3, and columniform rolling element 5 is installed between inner ring and outer ring, this rolling element is provided with axial bore, with left and right baffle plate and the riveted joint of cylindrical rolling element, between the two cylindrical rolling elements slider is housed by rivet, slider is loaded in the locating slot of baffle plate.

Embodiment 3, see Fig. 4, between adjacent two steel balls of ball bearing axial surface are housed and are the columniform slider of circular arc, and slider is provided with axial bore, and it is hinged that rivet passes the axial bore and the back-up ring of slider.

Also can make rivet through rolling element, slider place and the through hole that passes back-up ring rivet, rolling element, slider can be designed to solid.Back-up ring makes and extrudes the locating slot of dress slider with the sheet metal section bar.In the machine-building afterwards, can manufacture hollow body to rolling element to increase the centrifugal power of being used to, reduce friction factor.
