Abstract
The utility model relates to a novel deep groove ball bearing, which belongs to the technical field of bearings. The prior deep groove ball bearing has the defects that an inner dustproof cover and an outer dustproof cover are easy to be worn, and have complicated and difficult assembly. The novel deep groove ball bearing comprises an outer ring, an inner ring, a steel bead and a dustproof sealing ring, wherein the dustproof sealing ring consists of a dustproof cover and a sealing ring which are bonded together, and has relatively simple structure; the dustproof cover is arranged on the inner surface of the outer ring so as to form interference fit; a groove is arranged on the opposite surface of the sealing ring and the outer surface of the inner ring to form a contact lip which props against the inner ring, so that the dustproof and sealing effects are better and the novel deep groove ball bearing is hard to be worn.
Description
Technical field
The utility model belongs to technical field of bearings, and is especially relevant with a kind of novel deep groove ball bearing.
Background technique
Existing a kind of deep groove ball bearing as shown in Figure 1 and Figure 2 comprises outer ring 1, inner ring 4 and seal ring, seal ring is a combined type, form by the interior dust cover 3 of multilayer form, the 2 intersection butt joints of outer dust cover, outer dust cover 2 is installed on outer ring 1 internal surface and forms interference fit, the thickness sum of the interior dust cover 3 of inner ring 4 and both sides is suitable with the thickness of outer ring 1, by by shoulder interior dust cover 3 being pressed against inner ring 4 two ends on the axle, dust cover 3 is fixing with inner ring 4 in making during use.Such bearing is wiped to bump mutually easily in operation process and is caused wearing and tearing because there are concentricity in interior dust cover 3 and outer dust cover 2, reduces the working life of bearing, and the complicated difficulty of assembling.
The model utility content
The utility model purpose is exactly that the inside and outside dust cover that will solve above-mentioned deep groove ball bearing existence weares and teares, assembles complicated difficult defective easily, and the novel deep groove ball bearing that a kind of structure is simple relatively, dust sealing is effective and dust cover is not easy to wear and tear is provided.For this reason, the utility model is by the following technical solutions:
A kind of novel deep groove ball bearing, comprise outer ring, inner ring, steel ball and dust-proof seal ring, it is characterized in that: described dust-proof seal ring is made up of dust cover that sticks to one and seal ring, dust cover is installed on inner surface and forms interference fit, seal ring is provided with groove formation with the opposing side of inner ring outer surface and contacts lip, groove is used for oil storage and absorption dust, and the contact lip is resisted against inner ring and plays seal action.
The utility model can reach following beneficial effect: because dust cover and seal ring stick to one, make structure simple relatively, easy for installation, owing to be provided with oil storage grooves and contact lip and be resisted against inner ring, make dustproof and sealing effect better, and the area of contact of seal ring and inner ring is not easy to wear and tear for a short time.
