Abstract
The invention relates to a self-adjusting radial sliding bearing used in a high speed shaft, in particular to an automatic-adjusting radial sliding bearing used in a high speed shaft, to ensure the precise and stable operation of the high speed shaft in operating conditions. The sliding bearing mainly comprises a body, an outer ring part, a first node part and a second node part, and is characterized in that a first elastic groove and a second elastic groove, which are formed on the body, form the outer ring part and a tile part, and the tile part and the outer ring part are made into a whole; the automatic-adjusting function of the tile part under operating conditions is achieved through elastic deformation, and the adjusting function of the tile part is achieved through secondary elastic deformation. The sliding bearing has the advantages of simple structure, compactness and rationality, thus ensuring precise processing; and on the premise of ensuring high speed and stability, the sliding bearing has a small resonance swing, thereby being suitable for use on the occasions of high speed and light load (high speed centrifugal fan).
Description
Technical field
The present invention relates to a kind of self-adjusting integration type radial sliding bearing, specifically be used for the self-adjusting radial sliding bearing of high speed shaft energy, guarantee high speed shaft running accuracy and stationarity under the applying working condition, belong to the mechanical structure technical field.
Background technique
In prior art, the general employing of the high speed shaft of the high-speed centrifugal fan speedup box watt swinging mounting bearing that can incline, it mainly contains compositions such as outer ring, a plurality of tile, fulcrum.This kind bearing structure is complicated, processing cost height, the precision of the whole bearing of error effect of each part.In actual use, the resonance amplitude of this bearing is bigger.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of self-adjusting integration type radial sliding bearing is provided, simple in structure, easy to process, guarantee bearing accuracy easily, resonance amplitude is less.
According to technological scheme provided by the invention, self-adjusting integration type radial sliding bearing comprises body, and feature is that described body is provided with the first road elastic groove and the second road elastic groove forms outer ring portion and tile portion, and integrated type is made by tile portion and outer ring portion.Tile portion realizes automatic adjustment effect under its operating mode by resiliently deformable, and the corrective action of tile portion is realized by the secondary resiliently deformable.
Compared with the prior art the present invention has the following advantages:
This use new structure is simple, compact and reasonable; Can guarantee machining accuracy; Under the prerequisite that guarantees high stability, resonance amplitude is less; The occasion (high-speed centrifugal fan) that is particularly useful for high speed light loading.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure side view of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2: the present invention processes the first road elastic groove 2 and the second road elastic groove 3 on body 1, thereby forms the outer ring 1-1 of portion, the 1-2 of tile portion and two 1-3 of node portion, 1-4, and 1-2 of tile portion and the 1-1 of outer ring portion make integrated type.
Because each position so processing is simple and convenient, can be guaranteed the precision of bearing by forming (integrated type) on the body 1.Under applying working condition, pressure oil enters in the gap of bearing and high speed shaft kinematic pair by aperture 4, form dynamic pressure carrying oil film, because action of centrifugal force, the pressure at each position of oil film is different, in order to ensure minimum oil film and robust motion and precision, the 1-2 of tile portion realizes self-adjusting function by the distortion node 1-3 of portion, 1-4, wherein secondary distortion (the first road elastic groove 2 and the second road elastic groove 3) has strengthened the width of the automatic adjustment range of the 1-2 of tile portion, has widened the application area of this bearing.
Fact proved that resonance amplitude of the present invention is little, be applicable to fully on the high speed centrifugation wind to replace watt swinging mounting bearing that to incline.
