Abstract
The utility model discloses a water-lubricating dynamic-pressure rubber bearing which comprises a bearing steel jacket, a rubber inner liner, a dynamic and static pressure cavity and a water inlet and outlet hole, wherein, the rubber inner liner is arranged in the bearing steel jacket, an inner cavity of the rubber inner liner is provided with the dynamic and static pressure cavity, and the water inlet and outlet hole can be arranged on the wall of the bearing steel jacket. The utility model adopts radially symmetrical dynamic and static pressure cavity structure in a double-cavity type, which is easy to form stable hydrodynamic pressure water films and complete hydrodynamic lubrication states. The utility model has the characteristics of reduced friction coefficient and increased loading capacity and can be widely used for various types of industry, such as petroleum, chemical engineering, waterpower, mines, etc.
Description
One, technical field: the utility model relates to bearing, particularly a kind of water-lubricated dynamic rubber bush bearing.
Two, background technique: at present, rubber bush bearing commonly used, be generally eight vertical ditch ordinary water lubricating structures, though it has demonstrated its superiority for solving problems such as using the frequent bearing bush abrasion that occurs of metal sliding bearing, seal failure in the aqueous medium, but also exist simultaneously because groove is more, shortcomings such as general generating unit divided dynamic pressure effect and bullet stream effect during work, and its lubricating system also mostly is boundary lubrication, and overall bearing capacity is lower.
Three, summary of the invention: the purpose of this utility model provides a kind of improved, greasy property is good, overall bearing capacity is big water-lubricated dynamic rubber bush bearing, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art.
Water-lubricated dynamic rubber bush bearing described in the utility model comprises bearing steel bushing, elastometric lining, active and static pressure chamber and paddle hole, installs elastometric lining in the described bearing steel bushing, and the inner chamber of elastometric lining is provided with the active and static pressure chamber, and Bearing Steel puts and is provided with paddle hole.
Wherein, described active and static pressure chamber is the dual-chamber structure of radial symmetric, and paddle hole is located on the Bearing Steel jacket wall corresponding with it.
The utility model has following advantage compared with prior art:
1, adopts the bicavate active and static pressure cavity configuration of radial symmetric, the hydrodynamic moisture film that easier formation is stable;
2, be easy to form perfect fluid dynamic lubrication state, reduce friction factor, increase bearing capacity.
Four, description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 is for pressing structure schematic side view shown in Figure 1
Five, specific embodiment:
With reference to Fig. 1-Fig. 2, a kind of water-lubricated dynamic rubber bush bearing comprises bearing steel bushing, elastometric lining, active and static pressure chamber and paddle hole, installs elastometric lining 3 in the bearing steel bushing 2, the inner chamber of elastometric lining 3 is provided with active and static pressure chamber 1, and bearing steel bushing 2 walls are provided with the paddle hole 4 in order to voltage supply.Active and static pressure chamber 1 is the dual-chamber structure of radial symmetric, and Bearing Steel jacket wall corresponding with it is provided with the paddle hole 4 in order to voltage supply.
Claims (2)
1 one kinds of water-lubricated dynamic rubber bush bearings comprise bearing steel bushing, elastometric lining, active and static pressure chamber and paddle hole, it is characterized in that installing elastometric lining in the described bearing steel bushing, and the inner chamber of elastometric lining is provided with the active and static pressure chamber, and Bearing Steel puts and is provided with paddle hole.
2, water-lubricated dynamic rubber bush bearing according to claim 1 is characterized in that described active and static pressure chamber is the dual-chamber structure of radial symmetric, and paddle hole is located on its corresponding Bearing Steel jacket wall.
