Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-5, the present invention provides the following technical solutions: the utility model provides a convex type casing end face sealing pad, including sealing washer body 1, sealing washer body 1 includes casing contact surface 2 and end cover contact surface 3, the medial surface of sealing washer body 1 and be provided with centre bore 4 along the central line of sealing washer body 1, one side that centre bore 4 was kept away from to casing contact surface 2 is provided with axle along seal group 5, axle along seal group 5 includes external seal ring 6 and internal seal 7, the one end that external seal ring 6 kept away from end cover contact surface 3 is the loudspeaker form, the one end that end cover contact surface 3 was kept away from to internal seal 7 inclines to centre bore 4, the surface of sealing washer body 1 is provided with bump 8 and is the rectangle array distribution, casing contact surface 2 keeps away from the axle and is provided with triangle lug 9 along one side of seal group 5, the material of sealing washer body 1 is fluororubber.

In the embodiment, the appearance of the sealing ring body 1 can be different according to different use conditions such as different shapes of the machine shell, the appearance of the sealing ring body 1 is made to be different, when the sealing ring body 1 is assembled, the machine shell contact surface 2 is in contact with the end surface of the motor machine shell, the end cover contact surface 3 is in contact with the end surface of the end cover, the central hole 4 can avoid the motor rotor, the rotation of the motor rotor after the sealing gasket body 1 is installed is ensured not to be influenced, after the sealing ring body 1 is assembled, a shaft clings to the end surface along the sealing group 5, the outer sealing ring 6 is outwards bent along the central line of the machine shell, the inner sealing ring 7 is inwards bent along the central line of the machine shell, so that dust, water and the like outside the machine shell can not enter the machine shell, lubricating oil or cooling liquid and the like inside the machine shell can not leak to the outside of the machine shell, the sealing performance of the sealing ring body 1 is greatly enhanced, and the surface friction coefficient of the sealing ring body 1 is increased by the convex points 8, the condition that the assembly back sealing washer body 1 is difficult to appear skidding prevents that sealing washer body 1 from receiving to pull and take place to warp, damage, and sealing washer body 1 made by fluororubber not only ageing resistance is better, has better elastic damping moreover, receives after the extrusion and the extrusion face is seamless between the contact surface promptly, and this is the speciality commonly used of current sealing washer.

Specifically, the four corners of the sealing ring body 1 are rounded.

In this embodiment, the fillet is handled and is made the four corners of sealing washer body 1 smooth, is difficult for causing incised wound etc. to installer's hand.

Specifically, the number of the triangular projections 9 is four.

In this embodiment, each set of triangular protrusions 9 can be provided with a set of threaded holes, and can be screwed with a set of screws or bolts.

Specifically, a workpiece 10 and a cover plate 11 are respectively arranged on two sides of the seal ring body 1.

In this embodiment, the workpiece 10 may be a motor housing, or may be a mold for producing the sealing ring body 1, the cover plate 11 may be a motor end cover, or may be a mold for producing the sealing ring body, and when the workpiece 10 and the cover plate 11 are molds, the surface should have a groove corresponding to the salient point 8.

Specifically, the cover plate 11 is provided with a convex ring 12 along a center line of the cover plate 11 and on a side close to the seal ring body 1.

In this embodiment, when the seal ring body 1 is assembled, the convex ring 12 enters the central hole 4 and extrudes the seal ring body 1 toward the workpiece 10 at the central hole 4, so that the seal ring body 1 covers the inner edge of the end face of the workpiece 10, and the sealing performance is better.

Specifically, the inner side surface of the workpiece 10 is provided with a triangular groove 13 matched with the triangular bump 9.

In this embodiment, during the assembly, triangle lug 9 can be crowded into triangle recess 13 and blocked, can't appear the radial pivoted condition after making sealing washer body 1 installed, and the assembly is more firm, because a week and the casing terminal surface of assembly back triangle lug 9 keep extrudeing, can also avoid when because of bolt or screw are twisted in, sealing washer body 1 takes place to extrude and warp at screw or bolt department and lead to the sealing performance to descend.

The working principle and the using process of the utility model are as follows: during assembly, the machine shell contact surface 2 on the sealing ring body 1 is tightly attached to the machine shell end surface of the motor, the triangular lug 9 is aligned with the threaded hole on the machine shell end surface, then the end cover of the motor is additionally arranged, the end cover is tightly attached to the end cover contact surface 3, then a screw or a bolt is screwed into the threaded hole on the machine shell end surface, and the tip end of the screw or the bolt directly punctures the triangular lug 9 when contacting the triangular lug 9, so that the triangular lug 9 is squeezed into the triangular groove 13 and is clamped, thereby the sealing ring body 1 is well installed, the sealing ring body 1 cannot radially rotate, the assembly is firmer, because one circle of the triangular lug 9 keeps squeezing with the machine shell end surface after assembly, the sealing ring body 1 can be prevented from being deformed at the screw or the bolt when the bolt or the screw is screwed, the sealing performance is reduced, and during use, because the shaft is tightly attached to the end cover surface along the sealing group 5, and the outer sealing ring 6 bends outwards along the center line of the machine shell, and the inner sealing ring 7 bends inwards along the center line of the machine shell, so that dust, water and the like outside the machine shell can not enter the machine shell, lubricating oil or cooling liquid and the like inside the machine shell can not leak to the outside of the machine shell, and the sealing performance of the sealing ring body 1 is greatly enhanced.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
