Description
Technical field
The utility model belongs to machine field, the adjusting center bearing spider of more particularly to a kind of boiler blower.
Background technology
Boiler blower includes blower casing, and impeller is provided with blower casing body, and the outside of blower casing, which is provided with, drives
The motor of dynamic wheel rotation, generally, impeller is connected on the output shaft of motor, is cantilevered supporting way, in work
During work, impeller receives the resistance of air, the problem of bounce be present, and the operation to motor has an impact.
The content of the invention
For above-mentioned technical problem, the utility model devises a kind of adjusting center bearing spider of boiler blower, described
Bearing spider the other end of wind wheel is supported, and employ the design of spherical arc, you can with bearing block according to electricity
The error of the installation of machine output shaft carries out self-adjusting, reduces influence of the mismachining tolerance of blower casing to product after equipment, carries
The high quietness and stability of product.
The technical solution of the utility model is as follows：
The adjusting center bearing spider of boiler blower, it includes pedestal, and the left end face of pedestal is provided with installation cavity, pedestal
Right side be provided with the through hole that is connected with installation cavity, it is characterised in that：Described pedestal is close to the surface of right-hand member cambered surface spherical in shape.
Further, described installation cavity and through hole be on the same axis.
Further, the wall of described through hole is provided with several arc-shaped notch.
Further, the radius of described arc-shaped notch is 1.5mm, the center of circle and the through hole center of circle of adjacent arc-shaped notch
Between angle be 72 °.
In summary, the utility model has the advantages that：
The utility model devises a kind of adjusting center bearing spider of boiler blower, and described bearing spider is to wind wheel
The other end is supported, and employs the design of spherical arc, you can the mistake with bearing block according to the installation of motor output shaft
Difference carry out self-adjusting, reduce influence of the mismachining tolerance of blower casing to product after equipment, improve product quietness and
Stability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 be Fig. 1 be A-A to schematic cross-sectional view；
1 is pedestal in figure, and 2 be spherical arc, and 11 be installation cavity, and 12 be through hole, and 13 be arc-shaped notch.
Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the adjusting center bearing spider of boiler blower, it includes pedestal 1, the left end face of pedestal 1
Installation cavity 11 is provided with, the right side of pedestal 1 is provided with the through hole 12 connected with installation cavity, and described pedestal 1 is close to the surface of right-hand member
Cambered surface 2 spherical in shape, in use, bearing is arranged in installation cavity, the spherical arc and blower casing coordinate, when motor shaft with
During bearing fit, motor shaft there may be error when installing, and pedestal has the adjustment of an adaptability along spherical arc, reduce
Influence of the mismachining tolerance of blower casing to product after equipment, improve the quietness and stability of product.
Further, described installation cavity 11 and through hole 12 be on the same axis.
Further, the wall of described through hole 12 is provided with several arc-shaped notch 13, the arc-shaped notch energy of setting
Enough phases circumferential to bearing block, avoid bearing block from rotating.
Further, the radius of described arc-shaped notch 13 is 1.5mm, the center of circle of adjacent arc-shaped notch 13 and through hole
Angle between the center of circle is 72 °, and the connection reliability of arc-shaped notch is capable of using said structure design, is avoided due to fault of construction
The problem of causing bearing block to rotate.
Further, the pedestal in the utility model is process using ferrous based powder metallurgical, and surface is soaked with antirust oil.
In summary, the utility model has the advantages that：
The utility model devises a kind of adjusting center bearing spider of boiler blower, and described bearing spider is to wind wheel
The other end is supported, and employs the design of spherical arc, you can the mistake with bearing block according to the installation of motor output shaft
Difference carry out self-adjusting, reduce influence of the mismachining tolerance of blower casing to product after equipment, improve product quietness and
Stability.
The utility model is not limited to described embodiment, those skilled in the art do not depart from it is of the present utility model
In the i.e. open scope of spirit, it can still make some amendments or change, therefore rights protection scope of the present utility model is with claims
The scope of restriction is defined.
