Description
Technical field
The utility model belongs to the technical field of vertical pipeline mounted pump, more particularly to a kind of pivot structure of vertical pipeline mounted pump.
Background technology
Vertical pipeline mounted pump is a kind of motor-and-pump integrated, and compact-sized, installation floor space is small, pump easy to use.Mainly
It is similar to the liquid of clear water for conveying clear water or physicochemical properties, is widely used in fire demand water conveying, domestic water conveying,
The multiple fields such as cooling water circulation conveying.Currently, the pivot structure of vertical pipeline mounted pump used directly installs bearing in the market
In bearing block, in the case of high-speed rotation, bearing understands axial float, between the outer ring of bearing and bearing block may also occur
Gap causes bearing outer ring to be slided with bearing block.Secondly, bearing bearing and bearing block are metal material, are needed high
Machining accuracy can just be such that the two matches well, and processing difficulties are with high costs, in addition, vertical pipeline mounted pump often works in outdoor
Environment, circumstance of temperature difference is big, and excessive temperature change can cause the deformation of metal material, and bearing and bearing block contact is very tight
Close, deformation slightly can cause bearing to burst, and bring great security risk.
Utility model content
The utility model in view of the deficiencies of the prior art, provides a kind of pivot structure of vertical pipeline mounted pump, avoids bearing
The sliding of axial float and bearing outer ring and bearing block, while requirement on machining accuracy is reduced, save production cost.
The purpose of this utility model is achieved by following technical proposals：
A kind of pivot structure of vertical pipeline mounted pump, including rotor, bearing and bearing block, the rotor connect bearing, bearing
It being set in bearing block, which is characterized in that the pivot structure further includes bearing plate, and the bearing plate is loop configuration,
Its outer diameter is more than the outer diameter of bearing outer ring, and internal diameter is more than the outer diameter of bearing inner race, is less than the internal diameter of bearing outer ring, the bearing pressure
Plate is in close contact with bearing upper surface, and is fixedly connected with the bearing seat.
Preferably, the bearing plate is bolted with bearing block.
Preferably, the bearing plate has outwardly extending arcuate structure, is provided among arcuate structure for installing spiral shell
The circular mounting hole of bolt.
Preferably, there are two arcuate structures for the bearing plate tool, and radial symmetric is distributed.
Preferably, the circular mounting hole is surrounded with the installation groove for accommodating bolt.
Preferably, it is provided with loop buffer pad in the installation groove.
Preferably, the bearing block is provided with annular groove, and ring corresponding with annular groove is arranged in the bearing plate
Shape protrusion.
Compared to the prior art the utility model, has the advantages that:
1, the three-dimensional pipeline pump of the utility model uses bearing block and the common fixing bearing of bearing plate, turns in rotor high speed
When dynamic, axial play will not occur for bearing, even if in addition, the outer ring of bearing generates gap, bearing plate with bearing block
Presence can also avoid the sliding of bearing outer ring and bearing block.
2, the three-dimensional pipeline pump of the utility model not only uses bearing block fixing bearing, therefore allows bearing and bearing block
The dimensional tolerance for having bigger greatly reduces difficulty of processing, and then improves product qualification rate, reduces production cost.
3, there are the gaps of bigger due to allowing bearing and bearing block for the three-dimensional pipeline pump of the utility model, even if
In adverse circumstances, deformation caused by will not changing because of conditions such as temperature causes bearing to burst, and accident occurs.
4, the three-dimensional pipeline of the utility model is pumped through a variety of settings, strengthens the bonding strength of bearing plate and bearing block
With cooperation precision.

Specific implementation mode
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-4：
A kind of pivot structure of vertical pipeline mounted pump, including rotor 1, bearing 2 and bearing block 3, the rotor 1 connect bearing 2,
Bearing 2 is set in bearing block 3, and the pivot structure further includes bearing plate 4, and the bearing plate 4 is loop configuration, outside
Diameter is more than the outer diameter of 2 outer ring of bearing, and internal diameter is more than the outer diameter of 2 inner ring of bearing, is less than the internal diameter of 2 outer ring of bearing, the bearing pressure
Plate 4 is in close contact with 2 upper surface of bearing, and is fixedly connected with bearing block 3.
When installation, bearing 2 is put into bearing block 3, then bearing plate 4 is placed on to the upper table of bearing 2 and bearing block 3
Face keeps bearing plate 4 and bearing 2 concentric, and pushes down 2 outer ring of bearing, then bearing plate 4 is fixedly connected with bearing block 3.It uses
When, bearing plate 4 and bearing block 3 fix bearing 2 jointly, and when rotor 1 highly rotates, axial direction will not occur for bearing 2
Play, the outer ring of bearing 2 will not slide with the contact surface of bearing block 3, i.e. bearing is acted as a travelling agent circle.Described is fixedly connected
