Description
Technical field
This utility model relates to the sliding bearing that load is bigger, is specifically related to the self-lubricating plain bearing of a kind of band positioning key.
Background technology
Electrostatic precipitator is a kind of high-effective dust-removing equipment, quite varied in the application of each industrial circle.For the alkali recovery furnace electrostatic precipitator of paper industry, the mobility of its sode ash collected is very poor, so the bottom ash bucket of cleaner unit is changed into flat by taper, and on dust collector ash hopper base plate in installation ash bucket scrapper conveyor, promote the movement of sode ash with ash bucket scrapper conveyor.
Due to the operating mode extreme difference of cleaner unit, dust is many, and temperature is high; ash bucket scrapper conveyor power transmission shaft can only use sliding bearing, and the load of the power transmission shaft of ash bucket scrapper conveyor is very big, and bottom bearing, inner ring uses conventional straight pin location; use requirement cannot be met, often cause self-lubricating inner sleeve to act as a travelling agent circle.After inner sleeve abrasion, alignment pin also cannot take out replacing.
For this situation, it is necessary to design the self-lubricating plain bearing of a kind of band positioning key, effectively to solve above-mentioned technical problem.
Utility model content
The purpose of this utility model is aiming at the technical problem that ash bucket scrapper conveyor sliding bearing exists and the self-lubricating plain bearing of a kind of band positioning key designed, with the bearing damage avoiding sliding bearing to be caused because of problems such as loads very big, high temperature oil starvation, reduce simultaneously and save maintenance cost, and ensure the properly functioning of cleaner unit.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of self-lubricating plain bearing of band positioning key, it includes bearing base, self-lubricating inner sleeve bottom, self-lubricating inner sleeve top, positioning key, bearing block upper cover, bolt and alignment pin, it is characterized in that self-lubricating inner sleeve bottom is located in bearing base, fixed with bearing base by positioning key, limit the axial freedom of self-lubricating inner sleeve bottom, and it is combined into bearing block bottom part, self-lubricating inner sleeve top is located in bearing block upper cover, fixed by alignment pin, and it is combined into bearing block cover unit, bearing block cover unit is arranged on bearing block bottom part by bolt, it is combined into a complete plain bearing housing, bearing block upper cover seam pushes down positioning key and self-lubricating inner sleeve bottom, limit the rotary freedom of self-lubricating bearing inner sleeve bottom.
Described self-lubricating inner sleeve bottom and self-lubricating inner sleeve top composition self-lubricating bearing, its matrix material uses the material (such as tin bronze, steel alloy, magnesium iron, gray iron, macromolecular material etc.) that coefficient of friction is little, is inlaid with the self-lubricating materials such as graphite on matrix.
In technique scheme:
Positioning key on self-lubricating plain bearing base can be arranged on the position in the middle of self-lubricating inner sleeve bottom and bearing base, bearing block upper cover seam is pushed down self-lubricating inner sleeve bottom and makes it fixing with bearing base location by positioning key, being bolted bearing base and bearing block upper cover makes self-lubricating inner sleeve bottom and self-lubricating inner sleeve top be fixedly connected simultaneously, self-lubricating inner sleeve bottom, location and self-lubricating inner sleeve top make them will not produce displacement axially and in rotation simultaneously.
The utility model has the advantages that at operating mode extreme difference, dust is many, in the high environment that can only use sliding bearing of temperature, the power transmission shaft the biggest for load uses technique scheme, can effectively prevent the inner sleeve of self-lubricating bearing from acting as a travelling agent circle, and it is conveniently replaceable maintenance after self-lubricating bearing inner sleeve is worn and torn, it is ensured that cleaner unit properly functioning.
Below in conjunction with the accompanying drawings this utility model is described further.

Fig. 2 is this utility model inside configuration schematic diagram.
Fig. 3 is this utility model bearing block bottom part schematic diagram.
Fig. 4 is this utility model bearing block cover unit schematic diagram.
In figure: 1, bearing base 2, self-lubricating inner sleeve bottom 3, self-lubricating inner sleeve top 4, positioning key 5, bearing block upper cover 6, bolt 7, alignment pin.
Detailed description of the invention
As depicted in figs. 1 and 2, bearing base 1, self-lubricating inner sleeve bottom 2 and positioning key 4 form bearing block bottom part, self-lubricating inner sleeve top 3, bearing block upper cover 5 and alignment pin 7 form bearing block cover unit, bearing base 1 and bearing block upper cover 5 and couple combination by bolt 6.
As in figure 2 it is shown, bearing block upper cover 5 seam pushes down positioning key 4 and self-lubricating inner sleeve bottom 2, limit the rotary freedom of self-lubricating bearing inner sleeve bottom.
As it is shown on figure 3, self-lubricating inner sleeve bottom 2 is arranged in bearing base 1, is fixed with bearing base 1 by positioning key 4, limit the axial freedom of self-lubricating inner sleeve bottom 2 and be combined into bearing block bottom part.
As shown in Figure 4, self-lubricating inner sleeve top 3 is arranged in bearing block upper cover 5, is fixed by alignment pin 7, and is combined into bearing block cover unit.
