Abstract
The invention relates to the machining process of bearing units, and in particular relates to a machining process of bearing teeth with a novel sealing ring. The machining process is characterized by comprising comprises two processes, namely, turning machining and installing of a novel structure sealing ring, wherein in the turning machining, a numerical control precision turning machining process is adopted, and the surface roughness Ra is below 1.2. The machining process has the advantages that the grinding machining is canceled in the position in which teeth is arranged in the existing bearing sealing ring, only the precision numerical control turning machining process is adopted, the condition that the roughness of the machining process is in the same level with that of grinding, although spirals can be left through the machining process, the purpose of high sealing performance is achieved by improving the sealing ring and utilizing externally coated glue on a framework, and the machining process effectively improves the production efficiency and has a good sealing effect.

Described have a Novel sealing ring bearing, mainly comprises bearing inner race, bearing outer ring, seal ring of new structure, and it is characterized in that: described seal ring of new structure is installed on bearing age of a draught animal position.
Described seal ring of new structure is comprised of inner frame, rubber body and dust cover, inner frame and dust cover form sealed cavity, place the caulking gum body in the sealing cavity, it is characterized in that: described caulking gum body comprises the body of rubber that matches with the inner frame shape, the main lip that extends out on body of rubber, auxiliary lip and bilateral bead structure; Described auxiliary lip interference fit is on the inwall of dust cover; Described bilateral bead structure comprises first side lip and Second Edge lip, and first side lip and the equal interference fit of Second Edge lip are on the inwall of dust cover.
Further preferred, described first side lip and body of rubber are " L " shape of inclination, and its end interference fit is on the inwall of dust cover.
Further preferred, described first side lip and Second Edge lip are " U " shape fork structure that tilts, and the angle of inclination of two limit lips is slightly different, the length of first side lip is longer than the length of Second Edge lip, such structure has effectively guaranteed in the situation of first side lip seal performance failure, the Second Edge lip plays the effect of double seal protection, can prevent effectively also simultaneously that the first side lip is because of wearing and tearing, in the situation of its sealability total failure, the Second Edge lip plays the effect of salable protection, further improves working life.
Further preferred, described main lip and auxiliary lip are arch structure, are convenient to the rubber elasticity return.
Further preferred, the matching relationship of described main lip and dust cover is divided into two kinds of situations, and a kind of situation is that main lip interference fit is on the inwall of dust cover; Another kind of situation is the inwall that main lip does not contact dust cover.The form of these two kinds of main lips is to decide according to the situation of the interior pressure of main lip and extraneous Environmental Conditions, adopts main lip interference fit in the structural type of dust cover inwall when pressing high, extraneous dust or muddy water serious in main lip.
Beneficial effect of the present invention
The present invention installs age of a draught animal position at existing bearing sealed ring, has cancelled grinding, only uses accurate digital control turning manufacturing procedure, guarantees roughness and grinding peer-level; Although turning processing may leave spiral lamination, by improving seal ring, and utilize external coated rubber on skeleton to reach the purpose of high leak tightness; The present invention has effectively improved manufacturing efficiency and sealing effect is excellent.
