Abstract

The utility model provides an integral angle contact joint bearing hinged supporting base, which bears axial load and relatively large radial load simultaneously and fills a gap of domestic and overseas hinged supporting bases at present. The integral angle contact joint bearing hinged supporting base which simultaneously bears axial load and relatively large radial load utilizes combined paired angle contact joint bearings to form an integral body through a shaft and by coating a cast steel cylinder outside, and can reliably transmit relatively large axial load and radial load which are equal to each other basically.

Description

The angular contact articulated bearing pin rocker bearing

Technical field

The utility model is relevant for a kind of angular contact articulated bearing pin rocker bearing, and particularly relevant for a kind of angular contact articulated bearing pin rocker bearing that can bear thrust load and radial load simultaneously.

Background technique

In engineering practice, because of the structural system safety requirement, need the design pin rocker bearing, by the rotation release moment of flexure of mechanism.

Pin rocker bearing commonly used both at home and abroad at present is generally spherical mount, bearing pin bearing, neoprene bearing, but it all has Applicable scope separately.Two-way hinged when realizing, and two is all bigger to load, and during basic equivalent, above-mentioned bearing is all inapplicable.

The utility model can satisfy above-mentioned all requirements, and through improvement, can satisfy two kinds of situations of bearing pressure and pulling force simultaneously, more can seal, and guarantees not corroding of bearing, at the technical stability of building in service life.

The model utility content

In order to achieve the above object, the angular contact articulated bearing pin rocker bearing that the utility model provides a kind of integrated form to bear thrust load and big radial load simultaneously is to fill up at present the blank of pin rocker bearing both at home and abroad.

For this reason, the utility model provides a kind of integrated form to bear the angular contact articulated bearing pin rocker bearing of thrust load and big radial load simultaneously, employing is combined into right angular contact articulated bearing, form integral body by axle and overcoat cast steel tube, the larger axis of the basic equivalent of energy reliable delivery is to load and radial load.

Angular contact articulated bearing pin rocker bearing of the present utility model comprises: first joint shaft bearing; The second joint bearing; First with described first joint shaft bearing and second joint bearing hinge joint, described first joint shaft bearing and the same center of circle of second joint bearing, the same turning radius.

The utility model is that also described first joint shaft bearing and second joint bearing can rotate around three axles of global coordinate system.

The utility model also comprises: first sleeve covers described first joint shaft bearing; Second sleeve covers described second joint bearing; And second articulate described first sleeve and second sleeve.

The utility model is that also described first sleeve and second sleeve are the cast steel sleeve.

The utility model is that also described second has a through hole, and described first laterally is inserted in described second through hole.

The utility model is that also the size of described first joint shaft bearing and described second joint bearing is by its corresponding sphere diameter size value.

In sum, a kind of integrated form that the utility model provides bears the angular contact articulated bearing pin rocker bearing of thrust load and big radial load simultaneously, utilization is rationally integrated with each assembly, and calculate its bearing capacity by special-purpose formula, accurately determine each size of components, to satisfy special bearing power transmission designing requirement.

For above-mentioned feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Description of drawings

Figure 1 shows that the integrated form that the utility model one embodiment is provided bears the schematic cross-section that thrust load reaches the angular contact articulated bearing pin rocker bearing of big radial load simultaneously.

Embodiment

In order more to understand technology contents of the present utility model, especially exemplified by specific embodiment and cooperate appended graphic being described as follows.

In engineering practice, because of the structural system safety requirement, need the design pin rocker bearing, by the rotation release moment of flexure of mechanism.Pin rocker bearing commonly used both at home and abroad at present is generally spherical mount, bearing pin bearing, neoprene bearing, but it all has Applicable scope separately.Two-way hinged when realizing, and two is all bigger to load, and during basic equivalent, above-mentioned bearing is all inapplicable.And the utility model can satisfy above-mentioned all requirements, and through improvement, can satisfy two kinds of situations of bearing pressure and pulling force simultaneously, more can seal, and guarantees not corroding of bearing, at the technical stability of building in service life.

Figure 1 shows that the integrated form that the utility model one embodiment is provided bears the schematic cross-section that thrust load reaches the angular contact articulated bearing pin rocker bearing of big radial load simultaneously.As shown in Figure 1, pin 3 laterally is inserted in the through hole of cast steel sleeve 15, on pin 3, place axle head baffle plate 1 back inserting bolt 2, cast steel sleeve 14 is connected with second 16 with cast steel sleeve 15, first 13 through hole that laterally is inserted in second 16, bearing 12 is installed in first 13 place, seat hole, cover plate 11 is installed on the cast steel sleeve 14, oil sealing 7 is contained in placement pressing plate 6 in back on the cover plate 11, with first nut 5 of screwing on behind first double-screw bolt, the 4 insertion through holes, second double-screw bolt 8 is inserted in the tapping of cover plate 11, and second nut 9 and the 3rd nut 10 are screwed on second double-screw bolt 8.

Among the embodiment of the present utility model, be linked to be integral body, two groups of same centers of circle of bearing, the same turning radius by first 13 angular contact articulated bearing that will be provided with in pairs 12.When external load passes to above-mentioned axle, cause the distortion of axle, this moment, relative slippage took place in two groups of bearings on inside and outside ring interface separately, thereby realized rotating.The component package of inciting somebody to action wherein by cast steel sleeve 14 is isolated from the outside at last, avoids the corrosion of bearing, axle, guarantees that its turning power is not weakened.

Thus, the building structure that the utility model embodiment is provided by a series of assemblings that the assembly of special purposes is respectively arranged, is transmitted bigger load jointly, thereby has satisfied the pin rocker bearing performance requirement of this building structure.

Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; have in the technical field under any and know the knowledgeable usually; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking claims person of defining.
