Technical Field
The utility model relates to a slide bearing technical field, especially a water lubricated bearing.
Background
The water lubricated bearing adopts a mechanism that a metal outer ring is added with a rubber alloy lining, and part of water enters the inner surface of the rubber alloy lining to form a water film with high lubricity so as to improve the lubricating effect. For the water-lubricated bearing which is not immersed in water, after the bearing is used for a period of time, the water film is gradually dried due to the loss of water, and the lubricating effect is lost. Therefore, it is necessary to replenish water in a timely manner.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a can automatic water supply, keep better lubricated effect's water lubricated bearing to solve above-mentioned problem.
A water lubricated bearing comprises a metal outer ring and a rubber alloy bushing positioned on the inner side of the metal outer ring; a plurality of sunken shallow grooves are distributed on the inner side wall of the rubber alloy lining along the circumferential direction; a water storage ring groove is formed in the rubber alloy bushing; the middle of the bottom of the shallow groove is communicated with the water storage ring groove through a strip-shaped seam.
Further, the shape of the shallow groove is arc-shaped.
Further, each of the shallow grooves extends in the axial direction of the rubber alloy bushing.
Further, the maximum depth of the shallow grooves is less than 1 mm.
Further, the strip-shaped slit extends in the axial direction of the rubber alloy bushing.
Further, the width of the strip-shaped slit is less than 0.01 mm.
Furthermore, a water filling port communicated with the water storage ring groove is formed in one end face of the rubber alloy bushing.
Furthermore, a sealing plug is movably arranged at the water filling port.
Further, the thickness of the rubber alloy bushing is larger than or equal to that of the metal outer ring.
Furthermore, a limiting mechanism is arranged between the rubber alloy bushing and the metal outer ring.
Compared with the prior art, the water lubricating bearing of the utility model comprises a metal outer ring and a rubber alloy lining arranged at the inner side of the metal outer ring; a plurality of sunken shallow grooves are distributed on the inner side wall of the rubber alloy lining along the circumferential direction; a water storage ring groove is formed in the rubber alloy bushing; the middle of the bottom of the shallow groove is communicated with the water storage ring groove through a strip-shaped seam. So can automatic water supply, keep better lubricated effect.
Drawings
Embodiments of the present invention are described below with reference to the accompanying drawings, in which:
fig. 1 is a schematic perspective view of the water lubricated bearing provided by the present invention.
Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 1, the water lubricated bearing of the present invention includes a metal outer ring 10 and a rubber alloy bushing 20 located inside the metal outer ring 10.
A plurality of sunken arc-shaped shallow grooves 21 are circumferentially distributed on the inner side wall of the rubber alloy bushing 20, and water enters the shallow grooves 21 to be combined with powder generated by friction of the rubber alloy bushing 20 to form a water film. The maximum depth of the shallow grooves 21 is less than 1 mm.
Each shallow groove 21 extends in the axial direction of the rubber alloy bushing 20.
The rubber alloy bushing 20 is provided with a water storage ring groove 22 therein for storing a certain amount of water.
A strip-shaped seam 23 is communicated between the middle of the bottom of the shallow groove 21 and the water storage ring groove 22, and the width of the strip-shaped seam 23 is less than 0.01 mm. The strip-shaped slits 23 extend in the axial direction of the rubber alloy bushing 20.
The rubber alloy bush 20 is provided with a water filling port 24 on one end surface thereof, the water filling port 24 is communicated with the water storage ring groove 22, and a sealing plug is movably arranged at the water filling port 24.
In the present embodiment, the thickness of the rubber alloy bush 20 is equal to or greater than the thickness of the metal outer ring 10.
A limiting mechanism is further disposed between the rubber alloy bushing 20 and the metal outer ring 10, for example, a positioning groove is concavely disposed on the inner side wall of the metal outer ring 10, and a positioning bump is protrudingly disposed on the outer side wall of the rubber alloy bushing 20, and the positioning bump is located in the positioning groove. This prevents the rubber alloy bush 20 from moving or rotating relative to the metal outer ring 10.
When the water film is normal, the water film is accumulated in the shallow groove 21 due to the water pressure, so that the water in the water storage ring groove 22 can be prevented from further seeping out through the strip-shaped seam 23; when the water film is not available, the water in the water storage ring groove 22 seeps out into the shallow groove 21 through the strip-shaped seam 23, so that the normal work of the water film is maintained, and the good lubricating performance is kept.
Compared with the prior art, the water lubricating bearing of the utility model comprises a metal outer ring 10 and a rubber alloy bush 20 positioned at the inner side of the metal outer ring 10; a plurality of sunken shallow grooves 21 are distributed on the inner side wall of the rubber alloy bushing 20 along the circumferential direction; a water storage ring groove 22 is formed in the rubber alloy bushing 20; a strip-shaped seam 23 is communicated between the middle of the bottom of the shallow groove 21 and the water storage ring groove 22. So can automatic water supply, keep better lubricated effect.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
