Abstract
The utility model discloses a lubricated rubber bearing of water, including the metal outer lane and the rubber body. Interior rubber lath and outer rubber lath that the axial distributes are arranged to the internal skin of rubber, and the adjacent lath of interior rubber lath is equipped with inner water groove, and the adjacent lath of outer rubber lath is equipped with outer basin. Inner water groove links to each other with outside hydraulic system respectively with outer basin, the regular dimpling body of processing on interior rubber lath and the outer rubber lath. Can reduce the relative friction of friction between vice, prolonging life, damping fall and make an uproar, improve economic nature, and the tailing axle that is applicable to boats and ships, submarine etc. Holds.
Description
Technical field：
This utility model is related to a kind of bearing, more particularly to a kind of water lubricated rubber bearing for reducing friction.
Background technology：
Traditional water lubricated rubber bearing is one layer of rubber of sulfuration on metallic matrix bushing inwall, by metallic matrix and rubber
Glue-line is constituted, and axial tank is provided with rubber layer, and for lubricating and cooling down, the both sides of tank are rubber laths.
As bearing is integrally fixed on bearing block, rubber layer is not rotated with axle, the load that the rubber lath of bottom bears
It is larger with frictional force thus abrasion is the most serious, axle can be caused to sink, bending, and then cause a series of harm.
Additionally, submarine navigation device is difficult to form lubricating water film, shape between the special operation condition such as low speed, heavy duty lower axle and bearing
Into dry friction, easily rubber layer is burnt due to rubbing overheated.
The content of the invention
The purpose of this utility model is to provide a kind of water lubricated rubber bearing, can reduce rubbing relatively between friction pair
Wipe, improve the life-span.
For achieving the above object, the technical solution adopted in the utility model is：Including metal outer ring and rubber bodies.Rubber bodies
Ectonexine is disposed with the interior rubber lath and outer rubber lath of axially distribution, and the adjacent slat of interior rubber lath is provided with interior tank,
The adjacent slat of outer rubber lath is provided with external flume.Interior tank and external flume are connected with external hydraulic system respectively, interior rubber slab
Bar and outer rubber lath are provided with micro-bulge.
By such scheme, pressure differential is provided between described interior tank and external flume, is changed as needed.
By such scheme, the inner cylinder face chromium plating process of described metal outer ring 1.
When the shaft is rotated, can be by adjusting pressure differential, whether control rubber bodies are rotated with axle, make rubber bodies inner surface and
While axle is taken turns to operate to friction pair with rubber external surface and metal inner ring two, micro-bulge texture can be in the relative fortune of friction pair
Disorder of internal organs generation elastohydrodynamic lubrication, and the thickness of elastic lubrication fluid can be improved, reduce the coefficient of friction between friction pair.
Sliding friction can occur between interior rubber lath and axle, slip can occur between outer rubber lath and metal outer ring and rub
Wipe, so there are two pairs of friction pairs.So when rubber bodies rotate with the axis, due to the presence of micro-bulge on outer rubber lath, can
Make between outer rubber lath and metal outer ring, to produce elastohydrodynamic lubrication, improve the thickness of elastic lubrication fluid, reduce friction；In the same manner,
When rubber bodies are not rotated with axle, due to the presence of micro-bulge, two friction pairs produce elastohydrodynamic lubrication, improve elastic lubrication fluid
Thickness, reduce friction.
This utility model can reduce the Relative friction between friction pair as a result of said structure, improve the life-span, subtract
Shake noise reduction, improves economy.
Description of the drawings
Radial section schematic diagrams of the Fig. 1 for this utility model structure.
Fig. 2 is the close-up schematic view of micro-bulge structure at this utility model a.
In figure：1. metal outer ring, 2. in rubber lath, 3. in tank, 4. rubber bodies, 5 micro-bulges, 6. outer rubber lath,
7. external flume.
Specific embodiment：
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, this utility model includes metal outer ring 1 and rubber bodies 4, and 4 ectonexine of rubber bodies is disposed with axle
To the interior rubber lath 2 and outer rubber lath 6 of distribution, the adjacent slat of interior rubber lath 2 is provided with interior tank 3, outer rubber lath 6
Adjacent slat be provided with external flume 7.Interior rubber lath 2 and outer rubber lath 6 are provided with micro-bulge.The interior cylinder of metal outer ring 1
Face chromium plating process improves its wearability, corrosion resistance and surface smoothness.
In rubber body the external flume 7 of the interior tank 3 and outer rubber lath 6 of rubber slab bar 2 respectively with external hydraulic system phase
Even, the pressure between interior tank 3 and external flume 7 can be adjusted.When 2 pressure of interior tank on interior rubber lath 2 is sufficiently large, rubber
Colloid 4 does not rotate with the axis, and when 7 pressure of external flume on outer rubber lath 6 is larger, rubber bodies 4 are with axle synchronous rotary so that rubber
The interior rubber lath 2 of colloid 4 and outer rubber lath 6 rub uniformly, produce elastohydrodynamic lubrication.Two pairs of friction pairs take turns to operate, also
Frictional surface temperature can be avoided too high.
