Abstract
The utility model discloses a kind of water lubricated rubber bearing, comprise metal outer ring, metal inner ring and rubber layer, described rubber layer is arranged on the external cylindrical surface of metal inner ring, and the external cylindrical surface of described rubber layer is provided with gutter channel.For reducing corrosion, metal inner ring adopts bronze (ZCuSn10Zn2) or other corrosion-resistant metal materials.Because rubber layer is arranged on the external cylindrical surface of metal inner ring, with rotating shaft synchronous rotary, therefore greatly reduce the concentrated wear of rubber layer, improve working life.
Description
Technical field
The utility model relates to a kind of bearing, refers to a kind of water lubricated rubber bearing especially.
Background technique
Along with mankind's energy is day by day exhausted, environment goes from bad to worse, the saving design of material of engineering goods and environmental protection design concept more and more cause the attention of people.And water lubricated rubber bearing is pollution-free with it, material saving, low cost, wear-resistant, resistance to silt, the series of advantages such as corrosion-resistant and at boats and ships, water pump industry obtains extensive use becomes one of optimum bearing under water.
The vulcanization of rubber is generally fixed on bearing sleeve on bearing sleeve or by rubber lath and makes by existing water lubricated rubber bearing.Figure 1 shows that a kind of common structure of water lubricated rubber bearing, be made up of metal outer ring 1 and rubber layer 2, rubber layer 2 serves as a contrast on the inner cylindrical surface of metal outer ring 1; In order to lubrication and cooling, rubber layer is also provided with gutter channel 3.
During use, water lubricated rubber bearing is arranged on bearing support, and the rotating shaft that copper bush is housed rotates within the bearing, and because rubber layer does not rotate, the load of bearing bottom it and frictional force are comparatively large, and concentrated wear is serious, and working life shortens.In addition, water lubricated rubber bearing is higher to axle surface smoothness requirements, is difficult to meet the demands under in-site installation condition, also can cause the wearing and tearing of the rubber layer of water lubricated rubber bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber layer nonabradable water lubricated rubber bearing.
For achieving the above object, the water lubricated rubber bearing designed by the utility model, comprises metal outer ring, metal inner ring and rubber layer, and described rubber layer is arranged on the external cylindrical surface of metal inner ring, and the external cylindrical surface of described rubber layer is provided with gutter channel.For reducing corrosion, metal inner ring adopts bronze (ZCuSn10Zn2) or other corrosion-resistant metal materials.
Optionally, described rubber layer sulfuration or be bonded on the external cylindrical surface of metal inner ring.
Optionally, the inner cylindrical surface of described metal inner ring is provided with helical oil groove, the end face of described metal inner ring is provided with in-line, described helical oil groove is connected with in-line, described in-line is connected with external hydraulic system, adding oil pressure by hydraulic system can be linked on axle by inner ring distending, facilitates the installation of bearing.
Optionally, described gutter channel can be convex-surface type, concave shape or plane, is preferably plane.
The beneficial effects of the utility model are: 1) rubber layer is arranged on the outer surface of metal inner ring, along with metal inner ring and rotating shaft synchronous rotary, the each several part even wearing of rubber layer, there will not be the situation that concentrated wear is serious, extends the working life of water lubricated rubber bearing; 2) inner cylindrical surface of metal outer ring, namely has one side in relative rotation, can be beforehand with to obtain unusual light, reduce further the wearing and tearing of rubber layer with rubber layer, during in-site installation, the surface smoothness requirements of countershaft reduces simultaneously, and it is more convenient to install.
