Abstract
The utility model discloses a kind of water lubricating thrust bearing possessing new construction, including thrust bearing body, the shaped form gutter channel of the distribution clockwise being arranged on thrust bearing body end face and the obliquity prominence platform face between adjacent shaped form gutter channel, obliquity prominence platform face is downward-sloping while to b by a clockwise, and it forms angle theta with horizontal plane.Shaped form gutter channel is bigger than the contact area of parallel gutter channel, strengthens cooling, the cooling effect to motor.When the runner of thrust bearing becomes shaped form by linear pattern, thrust disc can be hindered to the centrifugal action of water, a part of water can be remained between gap, and the boss face contacted with thrust disc is the inclined-plane of a minute angle so that the lubricating water film between thrust disc and thrust bearing thickeies.Using submersible motor of the present utility model, the moisture film of thickening protects thrust disc and thrust bearing, prevents dry grinding, increases the service life.
Description
Technical field
The utility model belongs to submersible pump technical field, and in particular to a kind of water lubricating thrust bearing possessing new construction.
Background technology
At home, the wet motor used by submersible pump mainly uses hydrodynamic sliding bearing, and working media is water,
According to thrust disc and the working mechanism of thrust bearing, thrust disc is revolving part, and thrust bearing is fixture, in submersible electric motor just
In the normal course of work, one of effect of thrust bearing is exactly to cross water by tank to cool motor.The effect of thrust bearing
Two be that reaching certain speed can produce dynamic pressure to act on when thrust disc rotates with motor shaft, thrust disc and thrust bearing it
Between formed one layer of water lubrication film because the ratio of viscosities of water is relatively low, the thickness very little of water lubrication film makes bearing working in boundary friction
State, or even pressure is big sometimes, moisture film can also disappear, the thrust disc and thrust bearing dry wear for causing, reduction of service life, shadow
Ring the normal operation of motor.
Utility model content
The purpose of this utility model is to provide a kind of strengthens the water lubricating thrust bearing possessing new construction of effect of cooling.
To achieve these goals, the technical scheme that the utility model is taken is as follows：
A kind of water lubricating thrust bearing possessing new construction, including thrust bearing body, be arranged on thrust bearing body end face
The shaped form gutter channel being distributed clockwise and the obliquity prominence platform face between adjacent shaped form gutter channel；
The obliquity prominence platform face is downward-sloping while to b by a clockwise, and it forms angle theta with horizontal plane.
Used as further improvement of the utility model, the shaped form gutter channel is evenly distributed in thrust bearing body end
On face, its quantity is 12.
Used as further improvement of the utility model, the angle value scope of the angle theta is 0 ° of ＜ θ≤10 °.
Compared with prior art, having the beneficial effect that acquired by the utility model：
Major advantage of the present utility model is as follows：
1. shaped form gutter channel is bigger than the contact area of parallel gutter channel, strengthens cooling, the cooling effect to motor.
2. when the runner of thrust bearing becomes shaped form by linear pattern, thrust disc can be hindered the centrifugal action of water
Hinder, a part of water can be remained between gap, and the boss face contacted with thrust disc is the inclined-plane of a minute angle so that thrust
Lubricating water film between disk and thrust bearing thickeies.Using submersible motor of the present utility model, the moisture film of thickening protects thrust
Disk and thrust bearing, prevent dry grinding, increase the service life；The boss of curvilinear structures, thrust disc and thrust bearing can carry bigger
Axial compressive force, it is ensured that the normal operation of submersible motor, increase the service life.

Specific embodiment
Further details of narration is carried out to the utility model below in conjunction with accompanying drawing.
As shown in Figure 2-4, a kind of water lubricating thrust bearing possessing new construction, including thrust bearing body 2, it is arranged on thrust shaft
Hold the shaped form gutter channel 5 of distribution clockwise on the end face of body 2 and the inclination between adjacent shaped form gutter channel 5
Boss face 6；The obliquity prominence platform face 6 is downward-sloping while to b by a clockwise, and it forms angle theta with horizontal plane.The curve
Type gutter channel 5 is evenly distributed on thrust bearing body end face, and its quantity is 12.The angle value scope of the angle theta is
0 ° of ＜ θ≤10 °.
As shown in Figure 1, the parallel gutter channel 4 that conventional thrust bearing is set is parallel construction, adjacent, parallel gutter channel 4 it
Between conventional boss 3 also be horizontal end face.
As depicted in figures 5 and 6, this water lubricating thrust bearing possessing new construction is applied in submersible motor, thrust bearing body 2 with
Position relationship of the thrust disc 1 in submersible motor.
The shaped form gutter channel 5 that the utility model is used is bigger than the contact area of parallel gutter channel 4, strengthens to motor
Cooling, cooling effect.When the runner of thrust bearing becomes shaped form by linear pattern, centrifugal action meeting of the thrust disc 1 to water
Hindered, a part of water can be remained between gap, and the obliquity prominence platform face 6 contacted with thrust disc 1 is a minute angle
Inclined-plane so that the lubricating water film between thrust disc 1 and thrust bearing thickeies.Using submersible motor of the present utility model, thickening
Moisture film protects thrust disc 1 and thrust bearing, prevents dry grinding, increases the service life；The boss of curvilinear structures, thrust disc 1 and only
Thrust bearing can carry bigger axial compressive force, it is ensured that the normal operation of submersible motor, increase the service life.
The above implementation method is only preferred embodiment of the present utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, it is made on the premise of without departing substantially from the utility model principle and spirit
Any obvious change for going out, should all be contemplated as falling with claims of the present utility model.
