Abstract
The utility model relates to a rolling shaft, in particular to a rolling shaft for a duster. The rolling shaft comprises a shaft body, wherein the shaft body is provided with a soft protection layer; the protection layer is provided with a threaded groove for dusting, so that the rolling shaft can be subjected secondary dusting; the edge of the shaft body is chamfered; and the corner end of the groove is chamfered. In the rolling shaft for the duster disclosed by the utility model, the soft protection layer with the threaded groove is adopted, so that rolling shaft can be subjected to secondary dusting.
Description
Technical field
The utility model relates to a kind of roller bearing, especially a kind of dust removal machine roller bearing.
Background technology
Raising along with people's quality of the life, people are also increasing for the demand on floor, and dust removal machine need to be used in the industrial production floor in following process, and the roller surface on the common dust removal machine is smooth, in the figure that advances, easily produce and skid, and smooth surface also can't final dusting.
The utility model content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of dust removal machine roller bearing, solve that existing roller bearing easily skids and problem that can't final dusting.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of dust removal machine roller bearing; comprise axis body; be provided with the soft protective layer of one deck on the axis body, be provided with the screw-type groove for dust discharge on the protective layer, thereby can make roller bearing can carry out final dusting.
In order to reduce the frictional force of roller bearing and dust removal machine, the axis body edge adopts chamfered.
In order to prevent that dust is trapped in the groove, place, groove ends angle adopts chamfered.
The beneficial effects of the utility model are that dust removal machine of the present utility model adopts the soft protective layer of threaded type groove with roller bearing, make roller bearing can carry out final dusting.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. axis bodies among the figure, 2. protective layer, 3. groove.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of dust removal machine roller bearing as shown in Figure 1 comprises axis body 1, is provided with the soft protective layer of one deck 2 on the axis body 1, is provided with the screw-type groove 3 for dust discharge on the protective layer 2, thereby can make roller bearing can carry out final dusting.
In order to reduce the frictional force of roller bearing and dust removal machine, axis body 1 edge adopts chamfered.
