Abstract
The utility model discloses a carding machine upper roller bearing and relates to the field of textile machinery. The carding machine upper roller bearing consists of a bearing rod and a shaft sleeve, wherein a seal ring is arranged at the connecting part of the bearing rod and the shaft sleeve; one end of the sealing ring is clamped between the bearing rod and the shaft sleeve; the seal ring is step-shaped; the thickness of the sealing ring located at the exterior is larger than that of the sealing ring located between the bearing rod and the shaft sleeve. The carding machine upper roller bearing has the advantages that the structure is simple, the design is reasonable, due to the adoption of the step-shaped seal ring, the clearance between the shaft sleeve and the bearing rod is reduced, the clearance opening is plugged up like being plugged up by a bottle stopper, and the occurrence of the phenomenon that the bearing rod is wound by fibers is reduced.
Description
Technical field:
The utility model relates to field of textile machinery, is specifically related to carding machine upper roller bearing.
Background technology:
In textile enterprise, fiber is many and long, presently used upper roller bearing and axle sleeve inner width often have yarn fibers to stop up, and frictional force increases, and causes bearing rotating speed slack-off, power consumption is large, yarn fibers is longer, in the situation of enclosing around bearing one, is difficult to remove, accumulate over a long period, cause bearing to rotate.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provide have reduce fiber be stuck in the carding machine upper roller bearing in axle sleeve.
Technical problem to be solved in the utility model realizes by the following technical solutions.
Carding machine upper roller bearing, formed by bearing rod and axle sleeve, it is characterized in that: described bearing rod and axle sleeve junction are provided with sealing ring, and sealing ring one end is stuck in bearing rod and shaft room, sealing ring is stepped, is positioned at outside sealing ring thickness and is greater than the sealing ring that is positioned at bearing rod and shaft room.
Described bearing rod and the sealing ring of shaft room are provided with in the groove that protuberance is stuck in bearing rod, and sealing ring can not produce with bearing rod.
The described outside sealing ring cross section that is positioned at is right-angled trapezium, and outwardly, the thrust that sealing ring is released increases hypotenuse, reduces the probability that sealing ring produces.
The utility model is simple in structure, reasonable in design, stair-stepping sealing ring has not only reduced the gap between axle sleeve and bearing rod, and as bottle stopper, has blocked clearance aperture, has reduced fiber and be stuck in the generation of the phenomenon that is wound around bearing rod.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
1: bearing rod; 2: axle sleeve; 3: sealing ring; 4: protuberance; 5: groove.
Detailed description of the invention:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Carding machine upper roller bearing as shown in Figure 1, formed by bearing rod 1 and axle sleeve 2, bearing rod 1 is provided with sealing ring 3 with axle sleeve 2 junctions, sealing ring 3 one end are stuck between bearing rod 1 and axle sleeve 2, sealing ring 3 is stepped, is positioned at outside sealing ring 3 thickness and is greater than the sealing ring 3 that is positioned at bearing rod 1 and shaft room 2.Sealing ring 3 between bearing rod 1 and axle sleeve 2 is provided with in the groove 5 that protuberance 4 is stuck in bearing rod, and being positioned at outside sealing ring 3 cross sections is right-angled trapezium, and hypotenuse outwardly.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
