Abstract
The utility model belongs to a bearing, in particular relates to a combination hydrodynamic journal sliding bearing formed by combining a bushing bearing and a thrust slide bearing. The combination hydrodynamic journal sliding bearing comprises the bushing bearing, one end of the bushing bearing is provided with the thrust slide bearing, and the outer part of the bushing bearing is also provided with a main oil supply passage, wherein an oil supply hole of the thrust slide bearing is arranged between the thrust slide bearing and the main oil supply passage. The utility model has the advantages that the combination hydrodynamic journal sliding bearing is additionally provided with several oil supply holes compared with the prior hydrodynamic journal sliding bearing, because the oil supply hole of the thrust slide bearing is arranged between the thrust slide bearing and the main oil supply passage, pressure oil from the main oil supply passage is directly supplied for the thrust slide bearing so as to cause the thrust face of the thrust slide bearing to form a stable oil film, and the lubricating and the cooling effects of the bearing are strengthened.
Description
Technical field
The utility model belongs to a kind of bearing, is specifically related to a kind of combined liquid hydrodynamic sliding bearing that is combined by radial sliding bearing and thrust slide bearing.
Background technique
Existing Hydrodynamic Sliding Bearing is that thrust slide bearing and radial sliding bearing are separated basically, or radial sliding bearing has thrust face, but its thrust face is to utilize the no pressure oil that gushes from radial sliding bearing to lubricate, because it is lubricated that thrust face is no pressure oil, even can not guarantee to form stable oil film under design conditions.This bearing in actual applications often thrust face at first destroyed, thereby limited the application of liquid radial dynamic pressure sliding bearing.Particularly the occasion of high-speed overload is difficult to satisfy usage requirement.
Summary of the invention
The purpose of this utility model is that a kind of combined liquid hydrodynamic sliding bearing that can make radial sliding bearing part and thrust slide bearing part can form the stabilize oil film lubrication under design conditions is provided.
The utility model is to realize like this, a kind of combined liquid hydrodynamic sliding bearing, it comprises radial sliding bearing, end at radial sliding bearing is provided with thrust slide bearing, the outside of radial sliding bearing also is provided with total fuel feeding road, wherein, be provided with the thrust slide bearing oil supply hole between thrust slide bearing and the total oil circuit.
The utility model has the advantages that, compare with existing Hydrodynamic Sliding Bearing, the utility model has been set up several oil supply holes, owing between thrust slide bearing and total oil circuit, be provided with the thrust slide bearing oil supply hole, therefore the pressure oil that comes from total fuel feeding road directly is fed to the thrust slide bearing part, make the thrust face of thrust slide bearing can form stable oil film, strengthened the lubricated and cooling effect of bearing.
Description of drawings
Fig. 1 is the Hydrodynamic Sliding Bearing of existing band thrust face;
Fig. 2 is a combined liquid hydrodynamic sliding bearing provided by the present invention.
Among the figure, 5 total fuel feeding roads, 6 thrust slide bearing oil supply holes, 7 radial sliding bearings, 8 thrust slide bearings, 9 radial sliding bearing oil supply holes.
Embodiment
Below in conjunction with drawings and Examples the utility model is described as follows:
As shown in Figure 2, a kind of combined liquid hydrodynamic sliding bearing, it comprises radial sliding bearing 7 and thrust slide bearing 8, one end of radial sliding bearing 7 is provided with thrust slide bearing 8, the outside of radial sliding bearing 7 also is provided with total fuel feeding road 5, wherein, be provided with thrust slide bearing oil supply hole 6 between thrust slide bearing 8 and the total oil circuit 5.
The utility model is a kind of combined liquid hydrodynamic sliding bearing, mainly is used in high speed, the particularly occasion of high-speed overload, the occasion that high-accuracy rolling bearing is difficult to be competent at.Radial sliding bearing 7 parts and thrust slide bearing 8 parts all adopt the lubricated cooling of forced feed.In design conditions, two-part can form stable oil film, carrying radial force and end thrust.In high speed, particularly high-speed overload occasion, this bearing has wide application prospect.This combination bearing can be a drum type, elliptic, integrated type, split type, the inserted various forms that waits.And necessarily having thrust face with the rotating component of its work, thrust face can be a formula, also can be all-in-one-piece.Owing to be Hydrodynamic Sliding Bearing, must be equipped with stable total pressure oil supply system and effective unimpeded oil return system.The design method that can utilize traditional classics is to radially sliding bearing part and thrust slide bearing partly design.
Be illustrated in figure 1 as the Hydrodynamic Sliding Bearing of existing band thrust face, the radial sliding bearing part can form stable oil film in design conditions, but the thrust face part can not guarantee to form oil film, is at first destroyed, and this thrust face has limited the application of Hydrodynamic Sliding Bearing.
Fig. 2 is a combined liquid hydrodynamic sliding bearing provided by the present invention, and its characteristics are the oil supply hole more than at least 2, and the pressure oil that will come from total fuel feeding road directly is fed to the thrust-bearing part.
Under design conditions, radial sliding bearing 7 parts and thrust slide bearing 8 parts can both form stable oil film.In high speed, particularly the high-speed overload occasion has broad application prospects.Should emphasize, be Hydrodynamic Sliding Bearing owing to what relate to, is prerequisite at a high speed, because the formation that helps stablizing oil film at a high speed.How the difference of the present invention and existing structure has been several oil supply holes.Certainly, increase total fuel delivery and improve drainback passage.
