Description
Technical Field
The present utility model relates to a dynamic pressure sliding bearing, and more particularly, to a dynamic pressure sliding bearing having a self-aligning function.
Background
The dynamic pressure sliding bearing is an important part in mechanical equipment, and compared with a rolling bearing, the sliding bearing has the remarkable advantages of small friction resistance, high efficiency, good shock absorption performance and the like, and is very widely applied. The dynamic pressure sliding bearing has simple structure, mainly depends on the relative motion between the main shaft and the bearing, and forms a pressure liquid film between the bearing and the main shaft, and the necessary conditions of the working of the dynamic pressure sliding bearing include rotating speed, eccentricity and viscosity medium. In engineering practice, due to the influence of factors such as machining precision and assembly errors of the bearings, absolute centering is difficult to ensure between the bearings, and meanwhile, the force applied to the bearings can also present certain fluctuation along with the change of the operation working conditions of equipment, so that the dynamic pressure bearing is a main cause of accidents such as dry friction, damage, burning and the like in the operation process of the dynamic pressure bearing.
The conventional dynamic pressure sliding bearing and the support are rigidly arranged, and when the load applied to the main shaft fluctuates, accidents such as dry friction, damage, burning and the like are easy to occur between the shaft and the bearing.

Aiming at the defects in the prior art, the utility model aims to provide the dynamic pressure sliding bearing with the self-aligning function, the self-aligning function of the bearing is realized by means of the feedback function between the elastic element on the bearing body and the bearing capacity of the bearing, and meanwhile, the bearing has good economical efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
A dynamic pressure sliding bearing with self-aligning function comprises a bearing, a bearing seat, an upper elastic element and a lower elastic element;
the bearing is sleeved on the outer side of the main shaft;
The bearing is fixed on the bearing seat;
one end of the upper elastic element is connected with the top of the bearing seat;

The other end of the upper elastic element and the other end of the lower elastic element are connected with the bracket.
Preferably, the upper elastic element is connected with the bearing seat, and the lower elastic element is connected with the bearing seat through bolts.
Preferably, the upper elastic element is connected with the bracket, and the lower elastic element is connected with the bracket through bolts.
The dynamic pressure sliding bearing with the self-aligning function provided by the utility model realizes the self-aligning function of the bearing by means of the feedback function between the elastic element on the bearing body and the bearing capacity of the bearing, and has good economical efficiency, particularly the bearing applied to a vertical long-axis water pump, and has obvious advantages. The method has the following beneficial effects:
1) The dynamic pressure sliding bearing realizes self-aligning of the rotating shaft by means of feedback action between the elastic element on the bearing body and the bearing capacity of the bearing, and compared with the conventional dynamic pressure bearing, the dynamic pressure sliding bearing greatly reduces the eccentricity during operation and effectively avoids bearing abrasion caused by abrupt change of load during operation;
2) The dynamic pressure sliding bearing is easy to install and adjust, and the bearing can be quickly installed to the axle center position through the adjusting mechanism on the bearing body, so that a foundation is laid for the stable operation of the bearing from the installation angle;
3) The dynamic pressure sliding bearing has simple structure and good economical efficiency, is particularly applied to a vertical long-axis pump, can provide more stable support for a rotor by means of the elastic element on the bearing body, and has remarkable advantages.

Fig. 1 is a schematic view of the dynamic pressure sliding bearing of the present utility model.
Detailed Description
In order to better understand the above technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.
Referring to fig. 1, the dynamic pressure sliding bearing with self-aligning function provided by the utility model comprises a bearing 3, a bearing seat 2, an upper elastic element 1 and a lower elastic element 6.
The bearing 2 is fitted outside the spindle 5.
The bearing 2 is fixed on the bearing seat 2.
One end of the upper elastic element 1 is connected with the top of the bearing seat 2 through bolts.
One end of the lower elastic member 6 is connected to the bottom of the bearing housing 2 by a bolt.
The other end of the upper elastic element 1 and the other end of the lower elastic element 6 are connected with the bracket 4 through bolts.
When the main shaft 5 receives a radial force F in a rightward direction, the main shaft 5 moves rightward under the action of the radial force F, the eccentricity is e, the lubricating medium has viscosity, the lubricating medium is extruded along with the rotation of the main shaft 5 into the gap, the gap is smaller and smaller along with the rotation direction, the more serious the extruding degree of the lubricating medium is, the pressure of a liquid film generated in the bearing is increased, and therefore the purpose of bearing support is achieved.
According to the dynamic pressure sliding bearing, the bearing 3 is connected with the bracket 4 through the upper elastic element 1 and the lower elastic element 6, the bearing 3 can dynamically change according to load change by means of the upper elastic element 1 and the lower elastic element 6, when radial load on the main shaft 3 is suddenly increased due to abrupt change of the running working condition of equipment, the radial force is transmitted to the upper elastic element 1 and the lower elastic element 6 through the bearing 3 and the bearing seat 2, so that the upper elastic element 1 and the lower elastic element 6 correspondingly displace towards the stress direction, and accidents such as dry friction, damage and burnout between the shaft 5 and the bearing 3 are avoided; when the fluctuation of the working condition stops, the radial load on the main shaft 5 is reduced to a design value, and the upper elastic element 1 and the lower elastic element 6 return the bearing 3 to the design position, so that the self-aligning effect is realized.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
