Abstract
The utility model discloses a sliding bearing and is applied to a stainless steel centrifugal pump. The sliding bearing comprises a bearing outer ring and a bearing inner ring, wherein the bearing outer ring is nested in a shaft hole of an impeller of the stainless steel centrifugal pump in a fastening manner, the bearing inner ring is sleeved outside the rotating shaft and is in splined connection with the rotating shaft; and a friction pair provided with adaptive precision to a rotating bearing is formed between the bearing outer ring and the bearing inner ring. The sliding bearing provided by the utility model is composed of the outer ring and the inner ring, the long service life of the bearing is realized, and the use efficiency and safety of the whole equipment is ensured.
Description
Technical field
The utility model relates to a kind of bearing of machinery, particularly a kind of sliding bearing of stainless steel centrifugal pump.
Background technique
The sliding bearing that stainless steel centrifugal pump uses in the existing technology at present is generally the monocycle axle sleeve that graphite constitutes, and axle sleeve is embedded in the axis hole of impeller, and the inner hole sleeve of axle sleeve patches into rotating shaft, forms friction pair in relative rotation with rotating shaft.
The shortcoming of above-mentioned existing technology is; The bearing wear-resisting property that graphite material constitutes is poor, needs in the using process to change because of wearing and tearing continually, influences the utilization efficiency of equipment; The increase of radially going here and there when simultaneously wearing and tearing cause equipment operation continually influences the safe operation and the life-span of entire equipment.
The model utility content
The utility model is in order to overcome defective in the above-mentioned existing technology, can to realize the long lifetime operation of bearing, guaranteeing the utilization efficiency and the safety of entire equipment.
Be to realize above-mentioned purpose, the utility model provides a kind of sliding bearing, and it is applied to comprise in the stainless steel centrifugal pump: bearing outer ring, and it is fastening to be nested in the axis hole of stainless steel centrifugal pump impeller; Bearing inner race, its be socketed on rotating shaft outside and with rotating shaft between spline be connected; Constitute friction pair between bearing outer ring and the inner ring with rotary bearing accuracy of fit.
Wherein, the inner ring internal surface has the spline that a plurality of ring weeks evenly are provided with at interval, and spline and inner ring are one-body molded, and corresponding keyway is set in the rotating shaft.
Wherein, the spline quantity of inner ring can be three.The section of spline is diminishing trapezium structure entad.
Wherein, outer ring, inner ring constitute by Hard Alloy Steel.
Compared with prior art, the utlity model has following beneficial effect:
1, through be provided with one group respectively with the outer ring of impeller, the fastening socket of rotating shaft, the sliding bearing that inner ring constituted, realize the long lifetime operation of bearing, guarantee the utilization efficiency and the safety of entire equipment;
2, the concentrated spline fracture that causes of stress can be effectively avoided in the trapezium structure of spline design, can make spline more firm with cooperating of keyway;
3, the outer ring of Hard Alloy Steel formation and inner ring make less as the wearing and tearing between the inside and outside circle of friction pair.
Description of drawings
Fig. 1 is the radial cross-section of the utility model;
Fig. 2 is the axial sectional view of the utility model inner ring.
In conjunction with the accompanying drawing following reference character of mark above that:
The 1-impeller, 2-rotating shaft, 3-outer ring, 4-inner ring, 41-spline.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
The sliding bearing of the stainless steel centrifugal pump of the utility model is as shown in Figure 1, comprises bearing outer ring 3 and bearing inner race 4, and outer ring 3 is fastening to be nested in the axis hole of impeller 1.Inner ring 4 be socketed on rotating shaft 2 outside and with rotating shaft 2 between spline be connected.Outer ring 3, inner ring 4 are made up of Hard Alloy Steel, constitute the friction pair with rotary bearing accuracy of fit between outer ring 3 and the inner ring 4.
Further as shown in Figure 2; The internal surface of inner ring 4 has the spline 41 that three (can be more, not shown) rings week evenly is provided with, and spline 41 is one-body molded with inner ring 4; Corresponding keyway (not shown) is set in the rotating shaft 2, forms rotating shaft and the counterrotating constraint of inner ring.The section of spline 41 is diminishing trapezium structure entad.
The utility model through be provided with one group respectively with the outer ring of impeller, the fastening socket of rotating shaft, the sliding bearing that inner ring constituted, realize the long lifetime operation of bearing, guarantee the utilization efficiency and the safety of entire equipment.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
