Abstract
The utility model relates to the field of thin oil self-lubricating bearing boxes, and in particular relates to a rotary sealing device of a thin oil self-lubricating bearing box. The rotary sealing device is characterized in that a main spindle is fixedly arranged on a rolling bearing by a cup-shaped rotating body through threads, and the rolling bearing is arranged in a bearing box body; and a bearing box side cover is sheathed on the main spindle and arranged on the bearing box body, two to five sealing teeth are arranged on the bearing box side cover and are sealed by adopting packing seal, an oil leakage hole is formed in the bearing box side cover, and a bleeder plug screw is arranged at the upper part of the bearing box side cover. Due to the adoption of the technical scheme, the rotary sealing structure has the characteristics of being simple and durable in structure, reliable in running, free from maintenance and the like.
Description
Technical field
The utility model relates to thin oil self oiling bearing case field, is a kind of rotating sealing device of thin oil self oiling bearing case.
Background technique
Traditional thin oil self oiling bearing case adopts single outside framework oil seal (contact seal) structure, its main body is whole ring-type rubber product, by keeping interference fit to reach sealing effect with main shaft, main shaft and this oil sealing endoporus are in mutual Frotteurism always during use; In case sealing lost efficacy, must be with it vertically, lay down from spindle nose, renew oil envelope more again.So there is the defective that working life is short, change difficulty, poor reliability in traditional seal form.
Summary of the invention
The purpose of this utility model is that a kind of thin oil self oiling bearing case sealing that does not substantially need maintaining that reaches simple in structure, durable, reliable will be provided.
The technical solution of the utility model is: be comprised of cup-shaped solid of rotation, bearing housing side cover, bearing housing, rolling bearing and main shaft; It is characterized in that cup-shaped solid of rotation is fixed on main shaft on the rolling bearing by screw thread, rolling bearing is installed in the bearing housing; The bearing housing side cover is placed on the main shaft, is installed on the bearing housing, and the sealing tooth is arranged on the bearing housing side cover, and the sealing tooth number of teeth is 2～5 roads, adopts packing seal to seal, and is provided with the draining hole on the bearing housing side cover, and bearing housing side cover top is provided with bleed screw.
Owing to adopt technique scheme, have the characteristics such as not needing maintaining that reach simple in structure, durable, reliable.
Description of drawings
Fig. 1 is schematic representation of the present utility model.
In the drawings: 1, bleed screw; 2, cup-shaped solid of rotation; 3, bearing housing side cover; 4, packing seal; 5, sealing tooth; 6, draining hole; 7, bearing housing; 8, rolling bearing; 9, main shaft.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1, cup-shaped solid of rotation 2 is fixed on main shaft 9 on the rolling bearing 8 by screw thread, rolling bearing 8 is installed in the bearing housing 7, bearing housing side cover 3 is enclosed within on the main shaft 9, is contained on the bearing housing 7, and sealing tooth 5 is arranged on the bearing housing side cover 3, sealing tooth 5 numbers of teeth are 2～5 roads, adopt packing seal 4 to seal, be provided with draining hole 6 on the bearing housing side cover 3, bearing housing side cover 3 tops are provided with bleed screw 1.
Cup-shaped solid of rotation 2 guarantees the running-on assembly relation with bearing housing side cover 3.By combinations thereof formula seal form, the lubricant oil that stirs in the time of can effectively preventing the bearing High Rotation Speed leaks vertically.
Sealing tooth 5 structures are arranged on the bearing housing side cover 3, and sealing tooth 5 numbers of teeth are 2～5 roads; Adopt simultaneously packing seal 4 to seal, combine by multiple effective seal form, have good sealing effect.
Draining hole 6 is set on the bearing housing side cover 3, can effectively stops the lubricant oil by cup-shaped solid of rotation 2.
