Abstract
The utility model discloses a bearing which comprises a bearing outer ring, a bearing inner ring, steel balls, a retainer, rivets, a sealing ring and a dustproof cover. The sealing ring is provided with a first sealing lip, a second sealing lip, a third sealing lip and a tooth-shaped sealing lip. The first sealing lip presses the dustproof cover through a spring, the second sealing lip is in interference fit with the bearing inner ring, the third sealing lip is in interference fit with the dustproof cover, the tooth-shaped sealing lip is located on the outer side of the dustproof cover and is in clearance fit with the dustproof cover, and an antirust coating is plated on the surface of the dustproof cover. Through the facts that the first sealing lip, the second sealing lip, the third sealing lip and the tooth-shaped sealing lip are matched for sealing and the antirust coating is plated on the surface of the dustproof cover, the bearing is good in sealing effect and durable in service.
Description
Technical field
The utility model discloses a kind of bearing.
Background technique
Present bearing mostly is the sealing configuration of single form, only depend on the sealing of common seal ring and dust cover, its oil sealing and envelope dirt ability are difficult to meet consumers' demand, when bearing is worked, such as the occasion at high dust and muddy water, also can corrode peripheral dust cover under abominable working environment, and then affect working life of bearing, for this reason, need a kind of bearing that can address the above problem, satisfy the demand that bearing works with this under rugged environment.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of good sealing effect, long-lived bearing are provided.
For achieving the above object, the technical solution of the utility model is: a kind of bearing, comprise bearing outer ring, bearing inner race, be arranged on the steel ball between bearing outer ring and the bearing inner race, support the retainer of steel ball, the rivet of fastening retainer, place seal ring and the dust cover of steel ball periphery, described seal ring is provided with the first sealing lip, the second sealing lip, the 3rd sealing lip and dentation sealing lip, described the first sealing lip by spring compression on dust cover, described the second sealing lip and bearing inner race interference fit, described the 3rd sealing lip and dust cover interference fit, described dentation sealing lip is positioned at the dust cover outside, dentation sealing lip and dust cover Spielpassung, described dust cover surface is coated with rust preventive coating.
Described rust preventive coating is zinc coat.
Described rust preventive coating thickness is 2 μ m～5 μ m.
The beneficial effects of the utility model are: by the first sealing lip by spring compression on dust cover, the second sealing lip and bearing inner race interference fit, the 3rd sealing lip and dust cover interference fit, dentation sealing lip and dust cover Spielpassung, the dust cover surface is coated with rust preventive coating, good sealing effect is durable in use.
