Abstract

The invention provides a composite bearing bush strip and belongs to the field of mechanical manufacturing of bearings. The composite bearing bush strip comprises a metal lath skeleton, rubber layers and an abrasion-resistant layer. At least, the upper surface and the lower surface of the metal lath skeleton are wrapped with the rubber layers. The abrasion-resistant layer is attached to the upper surface of the metal lath skeleton upper surface rubber layer. The metal lath skeleton lower surface rubber layer is an installation fixing surface. According to the composite bearing bush strip, the excellent water lubrication performance of a plastic lath and the good vibration reduction buffering performance of a rubber lath are fully combined, the phenomena that shaft sticking, howling and the like are prone to appearing due to the fact that the rubber lath and a shaft are in a dry friction state is eliminated at the same time, and the defect that the vibration reduction buffering effect of the plastic lath is poor is also overcome; meanwhile, the composite bearing bush strip is formed by being hot-pressed and bonded with the abrasion-resistant layer (material) while the rubber layers are formed at the same time, so that the production process is simple, the production efficiency is high, and the product quality is stable; and the composite bearing bush strip can be widely used in ships, water pumps, water turbine units, the war industry and other fields.

Description

A kind of composite bearing watt bar
Technical field
The invention belongs to machine-building field of bearings, particularly to a kind of combined type bearing liner bar.
Technical background
Stern bearing is the important component part of marine propuision system, and its effect is supporting propeller shaft.Increase and the raising of the speed of a ship or plane along with the tonnage of ship; stern bearing is made to be in severe duty (lubricating status); thus produce serious friction, abrasion; cause seal failure in low speed, heavy duty, start, under some special operation conditions such as shutdown; severe lubricating status can cause axle journal and the raw vibration noise of bearing friction by-product, has a strong impact on the safety of submarine navigation device, disguise and survival ability.The friction of stern bearing, abrasion, noise have become the key factor threatening boats and ships reliability service.
Existing water lubriucated bearing, use both of which, one is plastic cylinder formula more, typical case such as Sai Long and Wei Gaoer, though water lubrication performance is fine, but the vibration reduction and cushioning performance of plastics is general;Another kind is abrasive rubber lath, though damping cushion effect is good, but in start and stop moment, is in dry condition and the phenomenons such as glutinous axle, whistle easily occurs, have a strong impact on safety problem between axle and lath.
Existing water lubriucated bearing, starts in a flash owing to naval vessel, hydrogenerator etc. run, is in dry condition between axle and bearing, and conventional bearings inner surface is rubber or glass fibre.Though rubber is provided that preferable flexible support, shaft plays a protective role, but because of its coefficient of friction compared with big, anti-wear performance is bad, then the glutinous phenomenon such as axle, whistle easily occur so that it is service life is substantially reduced;Though glass fibre has low-friction coefficient and good mill characteristic, but is not provided that preferable flexible support because its intensity is higher, the long-term shaft of meeting in the past cause fatal destruction, then have a strong impact on safety problem.
Summary of the invention
This patent purpose is to there is the glutinous technological deficiency such as axle, whistle under tradition water lubriucated bearing dry condition on startup to make up, a kind of combined type water lubriucated bearing is provided, ensure that naval vessel, hydrogenerator isometry can effectively reduce or eliminate the glutinous phenomenon such as axle, whistle on the basis of tying up to safe operation, it is thus possible to improve working environment.
As follows according to purpose of the present invention technical scheme: a kind of being combined holds bearing shell bar, including laths of metal skeleton, rubber rubber layer, wearing layer, described laths of metal skeleton is at least enclosed with rubber layer in upper and lower surface, with wearing layer above described laths of metal skeleton upper surface rubber layer, described laths of metal skeleton lower surface rubber layer is for installing stationary plane.
Further, laths of metal skeleton and lower surface rubber layer are provided with fixing hole.Bearing shell bar cross section use trapezium structure, upper and lower surface all uses face of cylinder arcuate structure, the axis on the upper face of cylinder to parallel with the axis on the lower face of cylinder, above cylinder diameter of a circle be less than or equal to following cylinder diameter of a circle.Wearing layer is macromolecule/non-metallic wear resistant layer material, selects one or more in the materials such as PAEK, politef, ultra high molecular polyethylene.Wearing layer material is PAEK+carbon nanometer, and its thickness is 5 ~ 8mm;Shore hardness 80 ~ 95 °, coefficient of friction≤0.018 when 60 ~ 80r.
One or more in modified butadiene acrylonitrile rubber, modified hydrogenated nitrile rubber, modified silicon rubber, the modified glue kind such as fluorubber, modified acrylic rubbers adopted by rubber layer material.Rubber layer material uses modified hydrogenated nitrile rubber, and thickness is 15 ~ 20mm;Shore hardness 75 ~ 80 °.Further, rubber layer needs to carry out post vulcanization, and the post vulcanization time controlled at 3 ~ 7 hours, and temperature controls between 140 ~ 210 DEG C.
During use, several bearing shell bars are bolted to round sleeve inner surface by fixing hole, form a circular configuration combined type water lubriucated bearing, its intermediate bushing bar cross section is trapezoidal or convex structure, a fixed gap is formed, it is simple to current and impurities in water are into or out along space between the most adjacent bearing shell bar.Combined type water lubriucated bearing detailed construction composition from inside to outside is respectively wearing layer, rubber bodies, rule and axle sleeve.The excellent specific property that this structure has given full play to wearing layer and bearing bed each material possesses self, can effectively make up and there is the glutinous technological deficiency such as axle, whistle under tradition water lubriucated bearing dry condition on startup.
The advantage of elastomeric material and high-abrasive material is combined for tube shaft bearing bearing shell bar by this invention, make it have the anti-wear performance of excellence and good mechanical property, this composite construction is to be hot bonding with wearing layer (material) in rubber layer molding to form simultaneously simultaneously, production technology is simple, production efficiency is high, constant product quality, product can be widely used in the fields such as boats and ships, water pump, water turbine set, military project.
