Abstract
The utility model discloses a kind of metering gear pump bearing, with for the axis hole with active axis connection, the one side of the axis hole is the working face cooperated with gear, the cricoid micro- bevel structure not contacted with gear face tilted down outward from center is formed on the working face, and the annular contact surface for cooperating with gear face is formed between cricoid micro- bevel structure and the axis hole.Since the area for contacting the working face of bearing with gear face reduces, the heat of generation decreases the utility model, to extend the service life of gear pump, improves the quality of product.
Description
Technical field
The utility model relates to metering gear pump technical fields, more particularly to a kind of metering gear pump bearing.
Background technique
In gear wheel metering pump operational process, the working face for connecting the bearing of driving shaft can be with the installed cooperation in side
The case where there is relative motion in the end face of gear, thus will appear fever, if the contact of the working face of bearing and the end face of gear
Area is larger, and the heat of generation is just relatively more, just will appear and wears very fast phenomenon.In this way, the longevity of gear pump will be reduced
Life, influences product quality.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of glue gear wheel metering pump
Bearing, to solve the problems, such as gear face and bearing face frictional heating.
It is for technical solution used by realization the purpose of this utility model:
A kind of metering gear pump bearing has for the axis hole with active axis connection, and the one side of the axis hole is and tooth
The working face for taking turns cooperation is formed on the working face cricoid from not contacting with gear face of tilting down outward of center
Micro- bevel structure forms the annular for cooperating with gear face between cricoid micro- bevel structure and the axis hole
Contact surface.
The gradient of micro- bevel structure is 0.5 degree
Compared with prior art, the utility model has the beneficial effects that
Since the area for contacting the working face of bearing with gear face reduces, the heat of generation also subtracts the utility model
It is few, to extend the service life of gear pump, improve the quality of product.
Detailed description of the invention
Fig. 1 show the diagrammatic cross-section of glue metering pump bearing；
Fig. 2 show the main view of glue metering pump bearing bearing；
Fig. 3 show the enlarged diagram of the part I in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1-3, a kind of metering gear pump bearing 1 of the utility model, has for the axis with active axis connection
Hole 2, the one side of the axis hole are the working face 3 cooperated with gear, are formed on the working face cricoid outside from center
The micro- bevel structure 4 not contacted with gear face tilted down, cricoid micro- bevel structure and the axis hole it
Between form annular contact surface 6 for cooperating with gear face.
Wherein, the starting point of micro- bevel structure 4 is the inner radius of the right side step surface of the axis hole, be can guarantee in this way
The area of micro- bevel structure 4 is greater than the area of the annular contact surface 6, this ensure that the end face of face of gear and bearing
1 contact surface is less and is also the cooperation for influencing gear and bearing.
Preferably, the gradient of micro- bevel structure is 0.5 degree, naturally it is also possible to be smaller.
In the utility model, due to adding one 0.5 on working face in bearing.Inclined-plane, guarantee the working face of bearing
The area contacted with gear face only have φ 85x φ 70 formed annular groove area, the end face of gear just with 0.5 ° of inclined-plane of bearing
Do not contact, in this way, the end face of gear and bearing working face would not large area friction, the heat of generation also can correspondingly subtract
It is few, it can thus extend the service life of gear pump, to improve the quality of product.
In the utility model, since the area that the working face of bearing is contacted with gear face reduces, the heat of generation
Reduce, to extend the service life of gear pump, improves the quality of product.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
