Water lubrication rubber alloy bearing

Abstract

The invention discloses a water lubrication rubber alloy bearing, which comprises a water lubrication rubber alloy bushing and a bearing outer ring. The water lubrication rubber alloy bushing is bonded on the inner circumference of the bearing outer ring through die stamping and vulcanizing, the corresponding coincidence relation is adopted for the radial thickness m of the water lubrication rubber alloy bushing according to the difference of the internal diameter d of the water lubrication rubber alloy bushing. The affect of the radial thickness of the water lubrication rubber inner liner to the bearing capacity and the shock resistant capability of the bearing is comprehensively considered in the water lubrication rubber alloy bearing, the corresponding thickness of the water lubrication rubber inner liner is adopted according to bearings with different specifications, the bearing capacity of the bearing is obviously enhanced, the properties of surface deformation compatibility and elastic fluid dynamic pressure lubrication and the good silt, sand and impurities drainage capacity are strengthened, the service life of the water lubrication rubber alloy bearing is more than three times the similar bearing, the water lubrication rubber alloy bearing has the advantages of vibration damping, noise reduction, abrasion resistance, reliability, high efficiency, energy conservation and environmental friendliness and can be widely applied to the fields of the engineering equipments of machinery, marine vessel, petroleum, chemical industry, mine, water conservancy, agriculture and national defense.

Description

technical field [0001] The invention relates to a transmission part, in particular to a water-lubricated rubber alloy bearing. Background technique [0002] Bearings are an indispensable part of mechanical transmission. Ordinary metal rolling and sliding bearings require lubricating oil for lubrication. Therefore, if they are applied to transmission machinery in contact with water, complex sealing components are required. If water enters the lubrication system, It is easy to cause bearing damage and failure, and even oil leakage and oil pollution of the water environment may occur. In the prior art, water-lubricated bearings are widely used in mechanical transmissions, especially propulsion systems such as ships. Water-lubricated bearings use water as a lubricating medium, which can well solve the above problems in terms of resource saving and environmental friendliness.

AI Technical Summary

Problems solved by technology

[0003] The water-lubricated bearing adopts the structure of the outer ring plus water-lubricated rubber material lining. In the prior art, the characteristics of the water-lubricated rubber material have not been considered comprehensively. In fact, the radial thickness of the water-lubricated rubber material lining has a great influence on the bearing capacity and bearing capacity of the bearing. The anti-seismic ability has a relatively important influence. The radial thickness of the lubricating rubber material lining in the prior art does not comprehensively consider the load-bearing capacity and anti-seismic capacity, so it cannot achieve the best match between the load-bearing capacity and the anti-seismic capacity, so there is friction and wear quickly. short lifespan

At the same time, the existing water-lubricated bearings are not strong enough to discharge sediment and impurities, which is also one of the reasons for fast friction and wear and short service life.
