Abstract
A self-lubricating bearing bush used for a water conservancy gate base includes a bush base body (1), wherein a plurality of pits (11) are formed on the bush base body (1), and a self-lubricating material (2) is fixed in the pits (11). A lubricating layer of the self-lubricating bearing bush is not liable to fall off, the wear resistance is better and the service life is longer.
Description
Technical field:
The utility model relates to the bearing shell technical field, bearing, the bearing shell used more specifically to water conservancy gate base.
Background technique:
Notice of authorization CN201301902Y, patent No. ZL200820191785.5 disclose a kind of water conservancy gate base selflubricating bearing shell, it is compared with the cast copper alloy bearing with steel bushing, improve two times its working life, adapt to the long-term underwater operation environment of water conservancy gate especially and use.Its deficiency is: the internal surface of its watt shape matrix is coated with polytetrafluorethylecoatings coatings, and polytetrafluorethylecoatings coatings easily comes off with a watt shape matrix in the working environment under water, can't work on after coming off, and needs to change, and is very inconvenient.
The model utility content:
The purpose of this utility model is exactly the deficiency at prior art, and provides a kind of water conservancy gate base selflubricating bearing shell, its lubricating layer difficult drop-off, long service life.
Technology solution of the present utility model is as follows:
A kind of water conservancy gate base selflubricating bearing shell comprises a watt shape matrix, forms some recesses on watt shape matrix, and self lubricating material is fixed in this recess, and self lubricating material slightly exposes recess.
Described self lubricating material is the sintering body of graphite and copper powder or the sintering body of teflon and copper powder.
The beneficial effects of the utility model are: when 1, self lubricating material is by heating watt shape matrix, high pressure presses knot to be fixed in the recess self lubricating material, form the lubricating layer that constitutes by several self lubricating materials at watt shape matrix surface, self lubricating material is fixing more firm with watt shape matrix like this, difficult drop-off has prolonged working life of product.
2, self lubricating material is the sintering body of graphite and copper powder or the sintering body of teflon and copper powder, and self lubricating material hardness is good, and wear resistance is strong.Compare as lubricating layer with the prior art polytetrafluorethylecoatings coatings, lubricating layer of the present utility model is more wear-resisting, and hardness is stronger.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a schematic perspective view of the present utility model
Among the figure: 1, watt shape matrix; 2, self lubricating material; 11, recess.
Embodiment:
Embodiment: see shown in Fig. 1,2 that a kind of water conservancy gate base selflubricating bearing shell comprises a watt shape matrix 1, forms some recesses 11 on watt shape matrix 1, self lubricating material 2 is fixed in this recess 11, and self lubricating material 2 slightly exposes recess 11.
Described self lubricating material 2 is the sintering body of graphite and copper powder or the sintering body of teflon and copper powder.
Working principle: self lubricating material 2 is selected the sintering body of graphite and copper powder or the sintering body of teflon and copper powder for use.Self lubricating material 2 is by heating watt shape matrix 1 time, high pressure presses knot to be fixed in the recess 11 self lubricating material 2, form the lubricating layer that constitutes by several self lubricating materials 2 on watt shape matrix 1 surface, self lubricating material 2 is fixing more firm with watt shape matrix 1 like this, difficult drop-off has prolonged working life of product.
Self lubricating material 2 is the sintering body of graphite and copper powder or the sintering body of teflon and copper powder, and self lubricating material hardness is good, and wear resistance is strong.Compare as lubricating layer with the prior art polytetrafluorethylecoatings coatings, the lubricating layer of being made up of several self lubricating material 2 upper surfaces of the present utility model is more wear-resisting, and hardness is stronger, longer service life.
Claims (2)
1. a water conservancy gate base selflubricating bearing shell comprises a watt shape matrix (1), it is characterized in that: form some recesses (11) on watt shape matrix (1), self lubricating material (2) is fixed in this recess (11), and self lubricating material (2) slightly exposes recess (11).
2. a kind of water conservancy gate base selflubricating bearing shell according to claim 1, it is characterized in that: self lubricating material (2) is graphite and the sintering body of copper powder or the sintering body of teflon and copper powder.
