Laths combined type water-lubricated rubber alloy bearing

Abstract

The invention discloses a laths combined type water-lubricated rubber alloy bearing. The bearing comprises sleeves, metal or non-metal lining plates, rubbers and the like, wherein the rubbers and the lining plates are precisely formed through moulding curing and are spliced into rubber alloy laths under high strength; the rubber alloy laths are assembled in parallel along the axial direction in inner holes of the sleeves and are uniformly distributed on the circumferences of the sleeves in a detachable manner so that the working interfaces of the rubber alloy laths have an elastic hydrodynamic lubrication structure organically combining multiple curves with circular arc-shaped grooves; and the rubber alloy laths and the sleeves can be combined into various large-size water-lubricated rubber alloy bearings. The rubber alloy bearing has the following beneficial effects: the invention provides an innovative design method and advanced manufacturing technology of the large-size water-lubricated rubber alloy bearings, thus not only greatly lowering the manufacturing cost but also solving the quality problem caused by difficult balanced control of pressure and temperature field during precise forming through moulding curing; and the water-lubricated rubber alloy bearing can be widely applied to various large and medium-sized ship propulsion systems and transmission machinery, has the advantages of high specific pressure, low noise, high reliability, long life, no pollution and the like, and is easy in installation under particular and extreme environments.

Description

technical field [0001] The invention relates to a water-lubricated rubber bearing, in particular to a strip-combined water-lubricated rubber alloy bearing. Background technique [0002] At present, water-lubricated rubber alloy bearings use new engineering composite materials instead of precious metals as the transmission material, and use natural water instead of mineral oil as the lubricating medium. It has the advantages of simple structure, saving mineral resources and no pollution to the environment. It has been used in various transmissions It is widely used in machinery such as ships, steam turbines, water pumps, washing machines, etc. [0003] However, water-lubricated rubber alloy bearings in various large and medium-sized transmission machinery, especially in ship propulsion systems, are in a state of boundary lubrication or even dry friction under special and extreme environmental conditions, and there are generally serious problems such as high noise, poor relia...

Problems solved by technology

[0003] However, water-lubricated rubber alloy bearings in various large and medium-sized transmission machinery, especially in ship propulsion systems, are in a state of boundary lubrication or even dry friction under special and extreme environmental conditions, and there are generally serious problems such as high noise, poor reliability, and short service life.

At the same time, most of the water-lubricated rubber alloy bearings in the prior art are monolithic, which not only causes various quality problems such as uneven vulcanization, rubber density, and uneven temperature and pressure during the precision molding of large-scale water-lubricated rubber alloy bearings. Poor, prone to air bubbles, etc., and the bearing shell cannot be reused

Chinese patent ZL200820190889.4 discloses a structural type of planar slatted water-lubricated composite material stern bearing. This planar slatted lubricating structure is not easy to form water film support under special and extreme environmental conditions, and its bearing capacity is poor. It is prone to squealing, poor vibration and shock resistance, and short service life.
