Description
Technical Field
The utility model relates to the technical field of sealing of electric motors, in particular to an oil storage type sealing ring applied to a small-sized electric motor.
Background
Electric motors have been widely used in various industries, along with the development of science and technology, many manufacturers have higher and higher requirements on the rotating speed of the electric motors, great challenges exist on the sealing performance of a sealing ring of a motor shaft, and the existing sealing ring cannot meet the technical development of the electric motor and is limited to be used in multiple occasions.
The sealing rings on the electric motor shafts in the existing market are simple in design, and the sealing effect is greatly limited due to the fact that only one sealing area is designed.
The existing sealing ring has the following defects:
(1) the sealing property is poor.
(2) The service life is short.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide an oil storage type sealing ring applied to a small electric motor, which has good sealing performance and long service life.
One of the purposes of the utility model is realized by adopting the following technical scheme: an oil storage type sealing ring applied to a small electric motor comprises a sealing ring body;
the outer wall of the sealing ring body is sequentially provided with a first area sealing rib and a second area sealing rib, the first area sealing rib is provided with a plurality of first convex surfaces, and the second area sealing rib is provided with a plurality of second convex surfaces; a plurality of outer diameter oil storage buffer grooves are formed between the first area sealing ribs and the second area sealing ribs; a plurality of inner diameter oil storage buffer grooves are formed in the inner wall of the sealing ring body.
Further, the first area sealing rib is provided with one first convex surface.
Further, the second area sealing rib is provided with two second convex surfaces.
Further, the first convex surface and the second convex surface are both arc convex surfaces.
Further, the radius of the first convex surface is 0.4mm, and the radius of the second convex surface is 0.5 mm.
Furthermore, the number of the outer diameter oil storage buffer grooves is one, and the number of the inner diameter oil storage buffer grooves is three.
Compared with the prior art, the utility model has the beneficial effects that:
an outer diameter oil storage buffer groove is arranged between the first area sealing rib and the second area sealing rib and is designed to absorb slight leakage grease stress; the first area sealing rib is arranged for preliminary sealing buffering, and the sealing capacity of the second area sealing rib is greatly improved, so that the service life of the sealing ring is greatly prolonged.
Drawings
Fig. 1 is a schematic structural diagram of an oil-storing seal ring for a small-sized electric motor according to an embodiment of the present invention.
In the figure: 1. a seal ring body; 2. a first convex surface; 3. a second convex surface; 4. an outer diameter oil storage buffer tank; 5. an inner diameter oil storage buffer tank.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1, an oil storage type seal ring for a small electric motor comprises a seal ring body 1; the outer wall of the sealing ring body 1 is sequentially provided with a first area sealing rib and a second area sealing rib, the first area sealing rib is provided with a plurality of first convex surfaces 2, and the second area sealing rib is provided with a plurality of second convex surfaces 3; a plurality of outer diameter oil storage buffer grooves 4 are formed between the first area sealing rib and the second area sealing rib; a plurality of inner diameter oil storage buffer grooves 5 are formed in the inner wall of the sealing ring body 1.
An outer diameter oil storage buffer groove 4 is arranged between the first area sealing rib and the second area sealing rib and is designed to absorb slight leakage grease stress; the first area sealing rib is arranged for preliminary sealing buffering, and the sealing capacity of the second area sealing rib is greatly improved, so that the service life of the sealing ring is greatly prolonged. In the embodiment, preferably, the first region sealing rib is provided with one first convex surface 2, the second region sealing rib is provided with two second convex surfaces 3, and the outer diameter oil storage buffer groove 4 and the inner diameter oil storage buffer groove 5 can buffer the sealing stress of the second region sealing rib;
further, the first-zone sealing rib is provided with a first convex surface 2.
Further, the second land sealing rib is provided with two second convex surfaces 3.
Further, the first convex surface 2 and the second convex surface 3 are both arc convex surfaces. The arc convex surface in this embodiment is not limited to other curved surfaces.
Further, the radius of the first convex surface 2 is 0.4mm, and the radius of the second convex surface 3 is 0.5 mm. Wherein, the radius of first convex surface 2 is R0.4mm's circular arc, because increase the sealed muscle of second district under the sealed muscle prerequisite of first district and better seal at electric motor during operation. The sealing stress of the second area sealing rib can be greatly buffered when the arc radius of the outer diameter oil storage buffer groove 4 is 0.5mm and the arc radius of the inner diameter oil storage buffer groove 5 is 0.2mm, wherein the arc radii of the first area sealing rib and the second area sealing rib are increased. The inner diameter oil storage buffer groove 5 is located between the first region sealing rib and the second region sealing rib in the embodiment. Through the sealing of the first district sealing rib, the second district sealing rib and outer diameter oil storage buffer slot 4, inner diameter oil storage buffer slot 5 to promote the leakproofness of sealing washer greatly, improve holistic life, satisfy more market demands.
Further, the number of the outer diameter oil storage buffer grooves 4 is one, and the number of the inner diameter oil storage buffer grooves 5 is three.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
