Description
Technical field
The utility model relates to bearing shell field, particularly relates to a kind of bearing shell of centrifugal air compressor main shaft bearing.
Background technique
Bearing shell is sliding bearing and the tactile part that is coupling, and is installed in the collar with bearings on axle, for playing support fixation to bearing.Therefore bearing shell should have larger bearing capacity and fatigue strength, there is good seizure resistance, embedding allowing property, compliance, anti-corrosion property and compressive strength simultaneously.
Although the bearing bush structure under prior art is each has something to recommend him, but all also there is different problems, because the gap between axle and bearing shell is very little, and the lubricant oil liquid that to be stickiness higher, mobility is poor, can not ensure that bearing shell inwall forms uniform oil film well.
Model utility content
The utility model object is for the above-mentioned technical problem existing for prior art, and bearing shell inwall forms uniform oil film to provide one to ensure well, the bearing shell of the simple a kind of centrifugal air compressor main shaft bearing of structure.
For achieving the above object, the utility model proposes a kind of bearing shell of centrifugal air compressor main shaft bearing, comprise top bearing shell and lower bearing, described top bearing shell is provided with the mounting groove of tiltedly corresponding two groups of locating studs and straight pin, described lower bearing is provided with the two group locating studs corresponding with top bearing shell and the mounting groove of straight pin, described top bearing shell and lower bearing are fixed together by locating stud and straight pin, described locating stud and straight pin are corresponding to be respectively arranged in the mounting groove of top bearing shell and lower bearing, the structure front portion of described top bearing shell and lower bearing composition is annulus post, rear portion is the annulus identical with annulus column internal diameter, described annulus column wall is alternately provided with a point oil groove, in described annulus, correspondence is provided with 12 oil-feed tanks, 12 corresponding filler openings are provided with outside annulus, described filler opening is cone shaped opening, conical cross section is drift angle is 90 degree of isosceles triangles, described oil-feed tank is communicated with filler opening.
As preferably, outside described annulus post, be provided with annular groove.
As preferably, described top bearing shell top is provided with locating stud mounting hole.
The utility model is evenly distributed with 12 pairs of oil-feed tanks and filler opening on bearing shell, and be provided with a point oil groove in annulus post, ensure the lubrication of bearing shell inwall, uniform oil film can be formed at bearing shell inwall, the utility model processing comparatively easily, not easy to wear, working life is longer, but also can prevent from causing when being engaged with public bearing shell killing.
