Abstract

The utility model discloses a rolling wheel bearing, which is characterized in that an axle housing composed of two ring sheets and a connecting column is arranged between an inner and an outer rings; the axle housing is provided with an axle hole or a rivet hole; the middle part of a rolling body is sheathed or fixedly connected with a rolling axle whose both ends are respectively sheathed or fixedly connected with the axle hole or the rivet hole of the axle housing; or the side wall of the groove of the inner ring or the outer ring of a rolling bearing is provided with the shaft hole or the rivet hole; both ends of a rolling wheel axle are respectively sheathed or fixedly connected with the axle hole or the rivet holearranged on the side wall of the groove. The utility model has the advantages of simple structure, easy fabrication, convenient cleaning and no locked phenomenon caused by oil pollution.

Description

Roller bearing

The utility model relates to a kind of mechanical transmission member, particularly a kind of roller bearing.

Existing market is sold and the rolling bearing of use is made up of inner ring, outer ring, rolling element and four elements of retainer.Inner ring and bearing are assembled together, and outer ring and bearing support are assembled together, and normally inner ring together turns round with axle, and the outer ring maintains static on bearing support; Also can the outer ring revolution, and inner ring is motionless, even also has Internal and external cycle to make different rotating speeds or different direction is rotating.Inside and outside circle all has groove, and rolling element just rolls along groove, and groove limits moving axially of rolling element on the one hand and plays the guide rail effect, also plays between reduction ball and seat ring contacting stress on the other hand for ball bearing.The effect of retainer is that adjacent rolling element is separated, and rolling element is evenly distributed along raceway.Rolling bearing can be divided into ball bearing by the shape difference of rolling element, roller bearing and taper roller bearing three classes, all there is following defective in the rolling bearing of that type at present, a retainer all must be arranged, rolling element is placed in the retainer, produce bigger force of sliding friction, hindering bearing rotates flexibly, to keep the set a distance that weighs relatively between rolling element in addition, rolling element and retainer gap are less, in use sneak into a small amount of greasy dirt the sliding power frictional force between ball and retainer will be increased rapidly, seriously occur locking phenomenon often, and have to clean and change, and cleaning is also more miscellaneous.Owing to use retainer, reduce the rolling element force of sliding friction, rolling bearing adopts ball to make rolling element more at present as far as possible, and the ball rolling element requires all complicated in manufacture view technology and equipment, its resistance to compression, shock resistance and load carrying capacity all a little less than, design specification also is subjected to the restriction of a lot of restraining factors.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rotational resistance little, on-stream flexibly steadily, anti-impact force is strong, the roller bearing that bearing structure is simple, rolling element is easy to manufacture.

The purpose of this utility model realizes by following technical proposals:

Between Internal and external cycle, establish a wheel cover of forming by two ring plates and attachment post, wheel puts and is provided with axle hole or rivet hole, rolling element middle part socket or be connected with the axis of rolling, axis hole or the capable socket of rivet hole or affixed that axis of rolling two ends put respectively at wheel, wheel and axle slide relative, or the recess sidewall on housing washer or inner ring is provided with axis hole or rivet hole, axis hole or the capable socket of rivet hole or affixed that the roller shaft two ends are provided with recess sidewall respectively.

Roller shaft can be an axis, also two semiaxis structures.

From above-mentioned situation as can be known the utility model purpose can realize, rolling element is that roller positions by wheel shaft and the recess sidewall of taking turns on cover or interior or circle or the outer ring, its adjustable gaps, removed support, reduced the roller force of sliding friction, even there is a small amount of greasy dirt also the locking situation can not occur, its cleaning is also easier.Owing to adopt the arbor wheel structure, rolling element can use manufacturing process and better simply cylindricality roller of equipment or dimension shape roller widely.Its resistance to compression, anti-impact force and load carrying capacity obviously strengthen, and its design specification can arbitrarily be adjusted as required.Can be designed to large-scale also programmable little shape.Use the various rolling bearings of very extensive alternative present use.

Accompanying drawing and drawing are described as follows:

Fig. 1 is a configuration diagram of the present utility model;

Fig. 2 is a structure sectional view of the present utility model.

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings below:

As shown in Figure 1 and Figure 2, establish a wheel cover 4 of being made up of two ring plates and attachment post in

inner ring

1 and 2 of outer rings, the attachment post number decide as required, and the utility model is selected 3 attachment posts for use, becomes to take turns body with two ring plates are affixed.Wheel puts and is provided with axle hole 6 or rivet hole, rolling element 3 middle part sockets or be connected with the axis of rolling 5, axis hole 6 or the capable socket of rivet hole or affixed that axis of rolling two ends put respectively at wheel, wheel and axle slide relative, or the recess sidewall on housing washer or inner ring is provided with axis hole or rivet hole, axis hole or the capable socket of rivet hole or affixed that the roller shaft two ends are provided with recess sidewall respectively.

Said roller shaft can be an axis, also can be two semiaxis, and the rolling element two ends are respectively established a projection replacement wheel shaft and also can be realized the purpose of this utility model certainly.Only need wheel shaft two ends with rolling element to socket-connect with axis hole on the recess sidewall on inner ring or the outer ring or rivet hole during assembling or rivet, rolling bearing pedestal installation is identical routinely for other.

The utility model is simple in structure, and is easy to manufacture, and it is convenient to clean, and can not produce locking phenomenon because of greasy dirt.

Claims

1, a kind of roller bearing is made of inner ring (1), outer ring (2) and rolling element (3), it is characterized in that: between Internal and external cycle, establish a wheel cover (4) of forming by two ring plates and attachment post, wheel puts and is provided with axle hole (6) or rivet hole, rolling element middle part socket or be connected with the axis of rolling (5), axis hole or the capable socket of rivet hole or affixed that axis of rolling two ends put respectively at wheel, or the recess sidewall on housing washer or inner ring is provided with axis hole or rivet hole, axis hole or the capable socket of rivet hole or affixed that the roller shaft two ends are provided with recess sidewall respectively.

2, roller bearing according to claim 1 is characterized in that: said roller shaft is axis or two semiaxis structures.
