The preferred constructive form of structure can be from circumferential direction in 180 degree to sealing ring ontology by being set to the reinforcing rib of annular
Play the role of enhancing fastening force and frictional force between inner ring and motor shaft, and prevents sealing ring from axial float occurs.
Preferably,
The sealing ring ontology 1 includes axis, and the reinforcing rib is multiple (preferably reinforcing rib is three), and multiple described
Reinforcing rib is along the axis direction parallel arrangement.It can pass through in this way in the axis direction of the sealing ring ontology of cyclic structure multiple
Reinforcing rib generates the multiple fastening force of multilayer and friction force effect between sealing ring ontology inner ring and motor shaft, improves fastening effect
Fruit further prevents sealing ring from falling off and play in an axial direction from axial.
Preferably,
It is equidistantly to arrange between multiple reinforcing ribs, the axial distance between adjacent said rib is equal.This is this practicality
The preferred arrangement form of multiple reinforcing ribs of novel sealing ring, can equally spacedly generate fastening force and friction in the axial direction
Power further prevents sealing ring play in the axial direction.
Preferably,
The axis direction of the reinforcing rib is parallel with the axis direction of the sealing ring ontology 1, alternatively, the reinforcing rib
Axis direction is tilted with the axis direction of the sealing ring ontology 1 and two axial lines intersect an angle.The axis of reinforcing rib is arranged
To be parallel with sealing ring body axis direction, the roughness and axial direction between reinforcing rib and motor shaft can be farthest promoted
Friction area promotes axial friction so that axial float is inhibited to the greatest extent.
Preferably,
When the axis direction of the axis direction of the reinforcing rib and the sealing ring ontology 1 tilts, the reinforcing rib
The number of degrees that axis intersects formed acute angle with the axis of the sealing ring ontology 1 are less than 45 °.
On the basis of the waterproof apron of original structure, add three or density uniformly and equidistantly in the internal diameter ring part of cushion rubber
Several, and the reinforcing rib (or cord) for being either slightly slanted certain angle (being less than 45 °) parallel with internal diameter annulus；In glue
Internal diameter is enclosed in the tight fit of axis outer diameter, the presence of reinforcing rib can prevent the axial float of cushion rubber, especially be slightly slanted
It may also suppress radial deflection or askew dress of the sealing ring relative to motor shaft, it is ensured that the water resistance of motor.
Preferably,

The further concrete structure of ontology is enclosed, sealing ring material is fluorubber (having elasticity and retractility to a certain extent), is one
The injection structure of kind rubber is represented in diagram with 3 reinforcing ribs by the new structural waterproof apron of design shown in Fig. 1-2
Several reinforcing ribs (mainly see the width of the internal diameter ring part of cushion rubber, it is wider, a plurality of reinforcing rib can be designed, it is narrow
Any, it is few)；Note that reinforcing rib is the structure with waterproof apron same material, injection molding together, it is the annulus of protrusion
Item (or fan-shaped item), is not groove, only raised reinforcing rib could increase waterproof apron internal diameter anchor ring and axis matching surface
Friction coefficient (frictional force), could more effectively prevent axial float of the waterproof apron on axis.
Preferably, the bulge-structure 2 makes with 1 integrated injection molding of sealing ring ontology.By by bulge-structure
It is made with sealing ring ontology integrated injection molding, the bond strength between bulge-structure and sealing ring ontology can be enhanced so that
Enhancing friction masterpiece can will not can not be played in motor work operational process relief structure with being fallen on sealing ring ontology
With improving fastening force and friction effect, further effectively prevent sealing ring that play occurs in the axial direction.
Other than it can bulge-structure be set on the internal diameter annulus of sealing ring, can also be in outer diameter annulus or lateral parts
Bulge-structure is set, mainly sees that waterproof apron is that the side is mutually fitted close with industrial motor parts, i.e., is set in the mating surface
Above-mentioned bulge-structure is set, can effectively increase the friction coefficient between sealing ring and component such as motor shaft, prevent close
Seal axial float from motor shaft；Add three or density uniformly and equidistantly several reinforcements in the internal diameter ring part of cushion rubber
Muscle；Reinforcing rib is parallel with internal diameter annulus or is slightly slanted certain angle (being less than 45 °)
As Fig. 3 the utility model also provides a kind of motor, including motor shaft, end cap and the sealing for being previously described for motor
Circle, wherein the position that the sealing ring is sheathed on the motor shaft and connects with the end cap.By in sealing ring ontology
