Description
Technical Field
The utility model relates to a grinding device, especially a special toper seal structure of grinding mechanism.
Background
In a machine seal structure of a grinding machine or the like, a seal structure including a seal groove and a seal ring is generally used to prevent leakage of seal oil or the like. The existing sealing structure usually adopts a combination of a rectangular groove (with a rectangular cross section) and an o-shaped sealing ring (with a circular cross section) (as shown in fig. 1 and 2), because the o-shaped sealing ring needs to be put in, the length of the rectangular groove is larger than the diameter of the o-shaped sealing ring, and because a gland is needed to press the o-shaped sealing ring to generate a sealing effect, the width of the rectangular groove is usually smaller than the diameter of the o-shaped sealing ring, when the gland presses the o-shaped sealing ring, the o-shaped sealing ring can only transversely seal the rectangular groove, and the o-shaped sealing ring can still longitudinally flow (as shown by an arrow in fig. 2). Although there are similar products on the market that improve this problem, such as using a profiled sealing ring (e.g. a Y-shaped sealing ring), it should be noted that the profiled sealing ring is not suitable for mass application in standardized mechanical equipment due to its extremely high production process requirements and poor product consistency, and the complicated installation procedure.
Disclosure of Invention
Not enough to prior art, the utility model provides an adopt o type sealing washer and improve special seal structure of machine that grinds of seal.
The technical scheme of the utility model is that:
the utility model provides a grind special toper seal structure of mechanism, it includes axle sleeve, outer gland, interior gland and bolt, the axle sleeve forms a sealed chamber with outer gland, and the sealed intracavity is filled the sealing liquid, and outer gland upper end extends the bulge loop to axle sleeve one side, and the axle sleeve outer wall then extends the flange to this bulge loop, and we hope in the industry that the bulge loop coincide completely between the flange, but based on machining's reality, this department can form a gap that sealed liquid can leak, so, bulge loop and flange form an outer inclined plane that leans out and an inner inclined plane of leanin respectively, and outer inclined plane and inner inclined plane form a cross-section and are conical annular, have placed an o type sealing washer in the annular, the bulge loop top has an interior gland through a plurality of bolt fastening, and interior gland covers bulge loop, o type sealing washer and flange top.
Specifically, the diameter of the o-shaped sealing ring is smaller than the width of the top of the ring groove but larger than the width of the middle part of the ring groove (the height of the conical half of the ring groove), so that the o-shaped sealing ring can be placed into the ring groove but cannot be excessively sunk into the ring groove, and the phenomenon that the inner gland cannot contact with the top of the o-shaped sealing ring is avoided.
Specifically, the through hole has been seted up corresponding to the bolt to interior gland, and the through hole divide into upper segment and hypomere, and the upper segment diameter is greater than the hypomere, and the upper segment is used for holding the head of bolt, and the hypomere is used for the nail portion of bolt to stretch out, the outer gland corresponds the bolt and is provided with the screw.
Specifically, the outer gland is provided with a mounting hole, which is convenient for the machine seal (containing the utility model) to be connected with the shell of the grinding machine.
Specifically, the outer gland upwards extends to form a protection ring in corresponding to the inner gland, and it makes the utility model discloses be difficult to collide with inner gland in storage, transport or the installation, reduce external force to seal structure's destruction.
The utility model has the advantages that: the standard O-shaped sealing ring is adopted, so that the cost is low, and the consistency is very high; the inner gland presses the o-shaped sealing ring downwards to enable the o-shaped sealing ring to be tightly attached to the outer inclined plane and the inner inclined plane, so that leakage of sealing liquid from one side of the outer gland or one side of the shaft sleeve is avoided, and the sealing performance is effectively improved.

FIG. 2 is an enlarged view of FIG. 1 at A;
FIG. 3 is a schematic structural view of the present invention;
fig. 4 is an enlarged view of fig. 3 at B.
In the figure, 1, an outer gland; 2. a shaft sleeve; 3. a convex ring; 4. a flange; 5. sealing the cavity; 6. an outer bevel; 7. an inner bevel; 8. an o-shaped seal ring; 9. an inner gland; 10. a bolt; 11. mounting holes; 12. a guard ring.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
the existing sealing structure usually adopts a combination of a rectangular groove (with a rectangular cross section) and an o-shaped sealing ring (with a circular cross section) (as shown in fig. 1 and 2), because the o-shaped sealing ring needs to be put in, the length of the rectangular groove is larger than the diameter of the o-shaped sealing ring, and because a gland is needed to press the o-shaped sealing ring to generate a sealing effect, the width of the rectangular groove is usually smaller than the diameter of the o-shaped sealing ring, when the gland presses the o-shaped sealing ring, the o-shaped sealing ring can only transversely seal the rectangular groove, and the o-shaped sealing ring can still longitudinally flow (as shown by an arrow in fig. 2).
Compared with the prior art, the structure of the utility model is as shown in figures 3 and 4:
the utility model provides a grind special toper seal structure of mechanism, it includes axle sleeve 2, outer gland 1, interior gland 9 and bolt 10, axle sleeve 2 forms a seal chamber 5 with outer gland 1, packs the sealing liquid in seal chamber 5, and outer gland 1 upper end extends bulge loop 3 to axle sleeve 2 one side, and axle sleeve 2 outer wall then extends flange 4 to this bulge loop 3, bulge loop 3 and flange 4 form an outer inclined plane 6 that leans out and an inner inclined plane 7 of leanin respectively, and outer inclined plane 6 and inner inclined plane 7 form a cross-section and are conical annular, have placed a O type sealing washer 8 in the annular, 3 tops of bulge loop are fixed with an interior gland 9 through a plurality of bolts 10, and interior gland 9 covers bulge loop 3, O type sealing washer 8 and flange 4 tops. In the figure, the o-shaped sealing ring 8 is circular, and the cross section of the o-shaped sealing ring 8 is necessarily circular in the relaxation state, but in practice, the o-shaped sealing ring is deformed into a triangle-like shape closely attached to the ring groove by the compression of the inner gland 9, and the o-shaped sealing ring is circular for convenience of illustration.
The diameter of the o-shaped sealing ring 8 is smaller than the width of the top of the ring groove but larger than the width of the middle part of the ring groove (the height of the conical half of the ring groove), so that the o-shaped sealing ring 8 can be placed into the ring groove but cannot be too sunk into the ring groove, and the situation that the inner gland 9 cannot contact the top of the o-shaped sealing ring 8 is avoided.
The inner gland 9 is provided with a through hole corresponding to the bolt 10, the through hole is divided into an upper section and a lower section, the diameter of the upper section is larger than that of the lower section, the upper section is used for accommodating the head of the bolt 10, the lower section is used for extending out of the nail part of the bolt 10, and the outer gland 1 is provided with a screw hole corresponding to the bolt 10.
Still be equipped with mounting hole 11 on the outer gland 1, be convenient for machine seal (having contained the utility model discloses) and the casing of grinding the machine are connected.
The foregoing embodiments and description have been provided to illustrate the principles and preferred embodiments of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
