Abstract

The utility model relates to a waterproof dust-preventing device of a lower bearing box of an edger mill, and belongs to the technical field of steel rolling of the metallurgical industry. According to the technical scheme, the waterproof dust-preventing device of the lower bearing box of the edger mill comprises a shoulder ring (1), a waterproof dust cover (2), an edging roll lower bearing box (3) and an edging roll (4), wherein the shoulder ring (1) is arranged at the lower shaft end of the edging roll (4), the edging roll lower bearing box (3) is arranged on a lower bearing of the edging roll (4), the waterproof dust cover (2) is arranged at the lower shaft end of the edging roll (4), and is arranged on the top of the edging roll lower bearing box (3), and the size of the waterproof dust cover (2) is matched with the size of the edging roll lower bearing box (3). When steel rolling is carried out, cooling water passes through the roll surface of a mill roll to downwards flow through the shoulder ring, and reaches the waterproof dust cover, the shoulder ring and the waterproof dust cover rotate along with the mill roll, water flow outwards scatters through acting force of rotation of the mill roll, so that the cooling water is prevented from entering the edging roll lower bearing box. The waterproof dust-preventing device of the lower bearing box of the edger mill has the advantages that the service life of a bearing is prolonged, production cost is reduced, the structure is simple, and use is convenient and safe.

Description

A kind of vertical miller lower bearing housing dust and water proof apparatus

Technical field

The utility model relates to a kind of vertical miller lower bearing housing dust and water proof apparatus, and especially narrow strip rolling mill edger roll lower bearing housing dust and water proof apparatus, belongs to metallurgy industry technical field of steel rolling.

Background technology

At present, in metallurgy industry ribbon steel production process, after vertical miller water quench roll, flow on lower bearing housing, from axle head, infiltrate bearing housing, water, slag mixture are sneaked in bearing grease, cause lubricating grease rotten, affect bearing service life, increase production cost.

Utility model content

The utility model object is to provide a kind of vertical miller lower bearing housing dust and water proof apparatus, avoids milling train cooling water to enter vertical miller lower bearing housing, improves bearing service life, solves the problem existing in background technology.

The technical solution of the utility model is:

A kind of vertical miller lower bearing housing dust and water proof apparatus, comprise retaining ring for shaft shoulder, water proof and dust proof cover, edger roll lower bearing housing and edger roll, retaining ring for shaft shoulder is located at edger roll lower shaft end, edger roll lower bearing is provided with edger roll lower bearing housing, water proof and dust proof is located at edger roll lower shaft end, and be positioned at edger roll lower bearing housing top, size matches with edger roll lower bearing housing.

Open Side Down for described water proof and dust proof cover, and prolong edger roll lower bearing housing lateral downward-extension.

During steel rolling, cooling water is through the roll surface retaining ring for shaft shoulder of flowing through downwards, and to water proof and dust proof cover, retaining ring for shaft shoulder and water proof and dust proof cover together rotate with roll, and current are outwards scattered under the active force of roll rotation, thereby have avoided cooling water to enter edger roll lower bearing housing.

The beneficial effects of the utility model are: avoid cooling water to enter edger roll lower bearing housing, improve bearing service life, reduce production costs, have feature simple in structure, easy to use, safe.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

In figure: retaining ring for shaft shoulder 1, water proof and dust proof cover 2, edger roll lower bearing housing 3, edger roll 4.

The specific embodiment

Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.

With reference to accompanying drawing 1, a kind of vertical miller lower bearing housing dust and water proof apparatus, comprise retaining ring for shaft shoulder 1, water proof and dust proof cover 2, edger roll lower bearing housing 3 and edger roll 4, retaining ring for shaft shoulder 1 is arranged on edger roll 4 lower shaft end, edger roll 4 lower bearings are provided with edger roll lower bearing housing 3, water proof and dust proof cover 2 is located at edger roll 4 lower shaft end, win and be installed togather by mistake with retaining ring for shaft shoulder 1, and be positioned at edger roll lower bearing housing 3 tops, Open Side Down, size matches with edger roll lower bearing housing 3, and prolongs edger roll lower bearing housing 3 lateral downward-extensions, and edger roll lower bearing housing 3 is covered.During steel rolling, cooling water is through the roll surface retaining ring for shaft shoulder of flowing through downwards, and to water proof and dust proof cover, retaining ring for shaft shoulder and water proof and dust proof cover together rotate with roll, and current are outwards scattered under the active force of roll rotation, thereby have avoided cooling water to enter edger roll lower bearing housing.
