Abstract
The utility model discloses a dustproof long cylindrical roller bearing, which is used for supporting a caster of a handcart and comprises a retainer and rollers. The retainer consists of retainer rings at two ends of the retainer and a support column connected with the retainer rings, the rollers are peripherally uniformly distributed along the retainer rings and are in rolling connection with the retainer rings, outer rings are arranged on the peripheries of the rollers, inner surfaces of the outer rings are in rolling contact with the rollers, and a dustproof cover is fixed to one side of each outer ring. The dustproof covers are disposed on one lateral surface, which is communicated with the external, of the bearing, so that the dustproof covers can effectively prevent external dust and the like from entering the bearing after the bearing is assembled on the caster, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to bearing manufacturing technology field, especially a kind of dust protected long cylindrical roller bearing that is used for the support of wheelbarrow castor.
Background technique
Wheelbarrow is widely used on supermarket, market and the production line, be used for the carrying of article, to save people's muscle power, the used castor of wheelbarrow passes through bearings, but also can be used in the relatively poor place of some environment sometimes, as industries such as casting, sandblast, floors, dust is more, because commonly used common long cylindrical roller bearing two ends and the external world lack effective sealing, it is inner and cause bearing wear that extraneous dust enters bearing easily, shortening bearing working life.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of dust protected long cylindrical roller bearing is provided, to improve the bearing seal effect, prolong bearing working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of dust protected long cylindrical roller bearing, being used for the wheelbarrow castor supports, comprise retainer and roller, retainer comprises back-up ring that is located at two ends and the pillar that is connected back-up ring, roller is circumferentially uniform along back-up ring, roller rolls with back-up ring and is connected, and the roller periphery is provided with the outer ring that internal surface contacts with the roller rolling, and a side of outer ring is fixed with dust cover.
The beneficial effects of the utility model are: the utility model is provided with dust cover at bearing with an extraneous side that communicates, like this after bearing is assemblied on the castor, dust cover can prevent effectively that extraneous dust etc. from entering bearing inside, prolongs the working life of bearing.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. retainers, 11. back-up rings, 12. pillars, 2. rollers, 3. outer rings, 4. dust covers among the figure
Embodiment
In conjunction with the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of dust protected long cylindrical roller bearing as shown in Figure 1, being used for the wheelbarrow castor supports, comprise retainer 1 and roller 2, retainer 1 comprises back-up ring 11 that is located at two ends and the pillar 12 that is connected back-up ring 11, roller 2 is circumferentially uniform along back-up ring 11, roller 2 rolls with back-up ring 11 and is connected, and roller 2 peripheries are provided with the outer ring 3 that internal surface contacts with roller 2 rollings, and a side of outer ring 3 is fixed with dust cover 4.After bearing was assemblied on the castor, dust cover 4 can prevent effectively that extraneous dust etc. from entering bearing inside, prolongs the working life of bearing.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
