Abstract
The utility model relates to a novel quill bearing which comprises an outer ring. A holder is arranged in the outer ring. A quill roller is arranged on the holder. The novel quill bearing is characterized in that the outer ring is further sleeved with an outer cover, an inner ring is further arranged in the holder, the two ends of the inner ring both extend out of the outer ring, and sealing is formed between the two ends of the inner ring and the outer cover. By means of the technical scheme, the novel quill bearing has the advantages that dust and impurities can be effectively prevented from entering the interior of the bearing, unnecessary abrasions on the bearing can be reduced, and the service life of the bearing can be prolonged.
Description
Technical field
The utility model relates to field of bearings, particularly a kind of novel needle bearing.
Background technique
Existing needle bearing, generally comprise outer ring, in described outer ring, be provided with retainer, described retainer is provided with needle roller, still, and the needle bearing of this structure, its structure is too simple, some dusts, impurity easily enter bearing inside, increase the unnecessary wearing and tearing of bearing, shorten the life-span of bearing.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of novel needle bearing, can avoid dust, impurity to enter bearing inside effectively, reduces the unnecessary wearing and tearing of bearing, extends bearing life.
The technical solution of the utility model: a kind of novel needle bearing, include outer ring, in described outer ring, be provided with retainer, described retainer is provided with needle roller, it is characterized in that: outside described outer ring, be also arranged with outer cover, in described retainer, be also provided with inner ring, described inner ring two ends all extend to outside outer ring, form sealing between described inner ring two ends and outer cover.
Adopt technique scheme, by the outer cover arranging, between inner ring two ends and outer cover, form sealing, can effectively avoid like this dust, impurity to enter bearing inside, reduce the unnecessary wearing and tearing of bearing, extend bearing life.
Further setting of the present utility model: be provided with seal ring between described inner ring one end and outer cover, form hard sealing between the other end of described inner ring and outer cover.
Adopt above-mentioned further setting, the sealing set-up mode of this structure, good sealing effect, and, easy to process.
Further setting more of the present utility model: described outer cover one end is the curved flange that is provided with inwardly, and described inner ring is outward extended with annular flange flange, forms the hard sealing of inner ring and outer cover on the outside end face of the annular flange flange described in described flange is pressed on.
Adopt above-mentioned further setting again, the hard sealing set-up mode of this structure, can play sealing effect well, can conveniently process again.
Further setting of the present utility model: described seal ring includes the ring skeleton that cross section is " L " and is coated on the annular sealing member on skeleton, on the end face of described seal, be positioned at skeleton corner location and be provided with annular groove, the inner ring face of described seal is provided with sealing lip, and described sealing lip and inner ring are conflicted.
Adopt above-mentionedly further to arrange, annular groove is arranged on to skeleton corner location, make like this elasticity of seal ring better, thereby make the good sealing effect between seal ring and inner ring, outer ring, and, positioning seal ring better.
Further setting more of the present utility model: one end that described inner ring is positioned at seal ring is arranged with dust cover, and described inner ring is provided with annular shoulder rank, and described dust cover is arranged on described shoulder rank.
Adopt above-mentioned further setting again, the dust cover of setting can further play dust-proof effect, and dust cover can be conveniently installed on the shoulder rank of setting.
Brief description of the drawings
