Abstract
The utility model discloses a bearing sleeve, particularly a bearing sleeve for a silicon carbide sliding bearing. The bearing sleeve for a silicon carbide sliding bearing is mainly used for shield pumps and magnetic pumps which convey mediums and for other machines. The bearing sleeve which forms a sleeve cylinder shape is characterized in that both end parts of the inner side of the bearing sleeve are provided with a fixed matching surfaces 1, the middle of the bearing sleeve is provided with a non-fixed matching surface 2, the middle of the outer side of the bearing sleeve is provided with a slide matching surface 3, and both ends of the bearing sleeve is provided with a non-slide matching surface 4. The utility model has the advantage that an automatic deformation is generated following the rise of temperature so as to compensate and suck the discrepancy of thermal expansion amount of a pump shaft and the silicon carbide sliding bearing sleeve without having large expansion to a silicon carbide sleeve arranged outside, so that the phenomenon that the silicon carbide sleeve is expanded to break is avoided, the use range of the pump is enlarged, the service life of the pump is prolonged, and the defects of the prior art are overcome.
Description
Technical field:
The utility model relates to a kind of sliding bearing sleeve, and particularly a kind of silicon carbide sliding bearing axle sleeve is mainly used on the canned motorpump and magnetic drive pump of fed sheet of a media, also can be used for other.
Background technique:
Canned motorpump and magnetic drive pump are widely used when fed sheet of a media, when especially carrying high temperature media on the chemical industry.The sliding bearing structure that uses is the axle sleeve that a carbon steel or stainless steel material are arranged at present, and the overcoat of a carbofrax material of its appearance suit forms friction pair between axle sleeve and the overcoat, and described axle sleeve is cylindric.Fastening being assemblied in of axle sleeve rotated on the pump shaft during use, rotates with pump shaft.Because the thermal expansion coefficient of carbofrax material is much smaller with respect to steel; when pump fed sheet of a media temperature was higher, it was broken usually can to cause the silicon carbide overcoat to be risen owing to the difference of thermal expansion amount, caused that whole pump damages; therefore the pump of this structure is subjected to the restriction of temperature, and using scope is limited to some extent.
Summary of the invention:
The purpose of this utility model provides a kind of transition axle sleeve that is used between silicon carbide sliding bearing sleeve and the axle, compensates and absorbs the different of the two thermal expansion amount, to overcome the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of silicon carbide sliding bearing axle sleeve, described axle sleeve is a sleeve shape, it is characterized in that: the inboard two end part of axle sleeve are secure fit face 1, and the middle part is an on-fixed fitting surface 2, the outer middle side part of axle sleeve is the face of being slidingly matched 3, and two ends are the non-face 4 that is slidingly matched.
Described axle sleeve is provided with cannelure 5.
Cannelure 5 on the described axle sleeve is three, evenly distributes.
The utility model compared with prior art has the advantage that the big tension of generation tool takes place from the difference of dynamic deformation, compensation and absorption pump shaft and silicon carbide sliding bearing sleeve thermal expansion amount, the silicon carbide in its outside to be overlapped with increase in temperature, thereby overcome the silicon carbide cover broken phenomenon that risen, increased the using scope of pump, improve its working life, overcome the deficiency of prior art.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a sectional schematic diagram shown in Figure 1;
Fig. 3 is the user mode figure of the utility model embodiment.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, 2: the two ends of axle sleeve cylindraceous inboard are the secure fit face 1 that is fastened on the axle, and intermediate portion is an on-fixed fitting surface 2, and promptly the internal diameter at on-fixed fitting surface 2 places is greater than the internal diameter at secure fit face 1 place at two ends.The outer middle side part of axle sleeve is the face of being slidingly matched 3, and two ends are the non-face 4 that is slidingly matched, and promptly the external diameter at Zhong Bu the face that is slidingly matched 3 places is greater than the external diameter of the non-face 4 that is slidingly matched at two ends.On axle sleeve, be processed with three equally distributed cannelures 5, promptly be mutually 120 degree angles.
As shown in Figure 3: secure fit face 1 fastening being assemblied on the axle 6 of axle sleeve, axle sleeve is rotated with axle 6, the position, intermediate portion is left axle 6 and is formed a space.The overcoat 7 of carbofrax material is assemblied on the outer bearing shell, the face that is slidingly matched 3 of the outside intermediate portion of axle sleeve and the overcoat 7 of the carbofrax material formation friction pair that is slidingly matched, the overcoat 7 that the non-face 4 that is slidingly matched at the two ends, the outside of axle sleeve leaves carbofrax material forms a gap.
During work because the medium temperature height, behind the axle sleeve expanded by heating because the existence of self shape and cannelure 5 can deform, the difference of compensation and absorption pump axle sleeve and silicon carbide sliding bearing sleeve thermal expansion amount, the silicon carbide to its outside overlaps the big tension of generation tool.
