Description

A kind of for the sealing configuration without mist of oil electro spindle
Technical field
The present invention relates to a kind of sealing configuration, particularly a kind of for the water proof and dust proof sealing configuration without mist of oil electro spindle.
Background technique
Compare the electro spindle of traditional oil mist lubrication, grease is used to lubricate without mist of oil energy-conserving and environment-protective electro spindle, therefore, for main shaft inner piece particularly bearing must ensure without any foreign material or water enter, affect the effect of bearing lubrication and the life-span of main shaft, therefore, adopt grease lubrication without mist of oil energy-conserving and environment-protective electro spindle, need a structure simple, easy for installation, front-end of spindle is provided to the sealing configuration of accurate protection, ensure normal operation and the working life of electro spindle, in prior art, lack this type of sealing configuration.
Model utility content
For the defect that prior art exists, the utility model provides a kind of for the sealing configuration without mist of oil electro spindle.
The utility model builds a kind of for the sealing configuration without mist of oil electro spindle, above-mentioned sealing configuration is arranged at the bearing front end of above-mentioned electro spindle rotating shaft external part, above-mentioned sealing configuration comprises the front axle gland be socketed successively, front nut, dust cover, above-mentioned front axle gland is enclosed within the outside of front nut, above-mentioned dust cover is fixed on shell, the inwall of above-mentioned dust cover by above-mentioned front nut compressing in front axle gland;
Above-mentioned front axle gland, front nut, dust cover are also respectively equipped with quantity annular recess not etc. and jut, above-mentioned multiple annular recess and jut form mazy type water proof and dust proof cavity, and above-mentioned cavity is also connected with the rhone be arranged on dust cover.
Further, the side of above-mentioned front nut is provided with three annular projection progressively raised by outside to axle center height.
Further, above-mentioned dust cover inwall is provided with two juts be slit into by a sunk part, above-mentioned jut is also arranged with two location counterbores.
Further, be provided with the depressed part corresponding with three annular projection on above-mentioned front nut in above-mentioned front axle gland, the outside of above-mentioned outermost depressed part is provided with multiple location counterbore, multiple tapped hole, multiple positioning through hole.
Compared with prior art, provided by the utility model a kind of for the sealing configuration without mist of oil electro spindle, there is structure simple, easy to install, the advantage that protection effect is good.
Accompanying drawing explanation
Fig. 1 is the utility model sealing configuration scheme of installation.
Fig. 2 is the front axle gland sectional view of the utility model sealing configuration.
Fig. 3 is the front nut sectional view of the utility model sealing configuration.
Fig. 4 is the dust cover sectional view of the utility model sealing configuration.
Embodiment
Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
Embodiment 1
As Figure 1-4, sealing configuration is arranged at outside the bearing of electro spindle rotating shaft 1 external part, sealing configuration comprises the front axle gland 2, front nut 3, the dust cover 4 that are socketed successively, front axle gland 2 is enclosed within the outside of front nut 3, dust cover 4 is fixed on the shell 5 of electro spindle, and front nut 3 is pressed in front axle gland 2 by the inwall of dust cover 4;
As Figure 1-4, front axle gland 2, front nut 3, dust cover 4 are also respectively equipped with quantity annular recess not etc. and jut, multiple annular recess and jut form mazy type water proof and dust proof cavity, and cavity is also connected with the rhone 401 be arranged on dust cover 4.
Further, as shown in Figure 2, the depressed part corresponding with three annular projection on front nut 3 is provided with in front axle gland 2, depressed part surrounded by annular projection 201,202,203, the outside of outermost depressed part is provided with multiple positioning through hole 204, multiple location counterbore, multiple tapped hole (not shown in FIG., with the axis being parallel of positioning through hole 204).
Further, as shown in Figure 3, the side of front nut 3 is provided with three annular projection 301,302,303 progressively raised by outside to axle center height.
Further, as shown in Figure 4, dust cover 4 inwall is provided with two juts 403 and 404 be divided into by a depressed part 402, jut is also arranged with two location counterbores 405.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection domain of the present utility model should define with the utility model claim is as the criterion.
