Abstract
The utility model relates to a rotating main shaft sealed structure. The rotating main shaft sealed structure comprises a shaft, a bearing, a box body, lip-shaped sealing rings, flange plates and bolts. The bearing is installed in a stepped hole of the box body. The shaft is installed in a bearing hole. The flange plates are fastened on the box body through the bolts. A groove is machined in the outer side of each flange plate. The lip-shaped sealing rings are installed on the grooves. A small gap with a certain length is arranged between an inner side hole of each flange plate and a rotating main shaft and used for sealing, a certain self-sealing effect can also be achieved through stickiness between oil films, and therefore leaking time of lubricating oil can be effectively prolonged. Besides, the lip-shaped sealing rings are installed outside the flange plates and can be conveniently and quickly replaced when worn under high-speed rotating of the main shaft, and work efficiency can be greatly improved.
Description
Technical field
The utility model relates to a kind of sealing configuration, and especially a kind of rotary main shaft sealing configuration belongs to the machinery industry technical field.
Background technique
In the lathe feed box, the sealing of rotary main shaft is very important, and particularly the feed box of at right angle setting use is filled lubricant oil in the feed box, and each parts of transmission are carried out sufficient lubrication, guarantees the stability of production and processing.In the prior art, the design that the rotary main shaft sealing configuration adopts usually is that shoulder hole is processed in the flange plate inboard, lay the structure of hermetic oil seal, under the long-term High Rotation Speed of main shaft, oil sealing weares and teares, the sealing effect variation, there are a large amount of lubricant oil to reveal from main shaft, need to pull down flange plate like this, change seal ring, affect work efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of a kind of rotary main shaft sealing configuration simple in structure, ingenious, rational is provided, and the sealing structure can effectively prolong the rear Leakage of rotary main shaft wearing and tearing, and can improve work efficiency.
The technological scheme that provides according to the utility model: a kind of rotary main shaft sealing configuration comprises axle, bearing, casing, lip-type packing, flange plate, bolt; Described bearing is installed in the shoulder hole of casing, and axle is installed in the bearing hole, and on casing, the described flange plate outside processes a groove to flange plate by bolton, and groove is installed lip-type packing.
As further improvement of the utility model, described flange plate inboard aperture contacts with main shaft and is Spielpassung, by the oil-film viscous selfsealings.
The utility model compared with prior art has the little clearance seal of a segment length between flange plate inboard aperture and rotary main shaft, also play certain self sealing action by the viscosity between oil film, has prolonged the leakage time of lubricant oil; In addition, lip-type packing is installed in the flange plate outside, and it is convenient to change after the wearing and tearing under the main shaft High Rotation Speed, quick, has greatly improved working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described a kind of rotary main shaft sealing configuration mainly comprises axle 1, bearing 2, casing 3, lip-type packing 4, flange plate 5 and bolt 6.
The utility model adopts bearing 2 to be installed in the shoulder hole of casing 3, axle 1 is installed in bearing 2 holes, flange plate 5 is fastened on the casing 3 by bolt 6, described flange plate 5 outsides process a groove, groove is installed lip-type packing 4, and it is convenient to change after the wearing and tearing under the main shaft High Rotation Speed, quick, greatly improved working efficiency, main shaft has been sealed.Flange plate 5 inboard aperture and main shaft 1 have the little Spielpassung of a segment length, by the oil-film viscous selfsealings, can prolong the leakage time of lubricant oil.
