Abstract
A high-performance self-lubricating double-hemisphere bearing relates to a bearing comprising unique composites and solid lubricating particles, and has very good abrasive resistance, very low coefficient of thermal expansion and extreme low density, thereby ensuring that the bearing can have excellent size stability and abrasive resistance no matter in a polar region or a tropical ocean environment, and facilitating installation and maintenance. A unique oil groove design and a seam separation port design provide conveniences for adding lubricating oil after long-term use in a severe environment, and the high-performance self-lubricating double-hemisphere bearing is simple and convenient to process and mount.
Description
Technical field
The utility model relates to a kind of bearing, and the two hemisphere bearings of particularly a kind of high-performance selflubricating are applicable in the earrings of marine ships oil cylinder both sides.
Background technique
Along with rapid economy development, economic trade contact has constantly driven development, especially the marine ships traffic tool of transportation, and the ship hydraulic oil cylinder is a power tool important on the boats and ships.Marine climate variability, environment is abominable, and is also quite harsh to the design of hydraulic jack.Bearing is to alleviate oil cylinder piston bar motion active force.In navigation,, can not get lubricated effectively because the oil cylinder earrings is exposed to the oil cylinder outside always; Add the influence of seawater humidity; Can cause ball bearing be prone to get rusty, not corrosion-resistant, make the contact surface wearing and tearing of ball bearing, send noise; Even cause serious clamping stagnation inefficacy, finally cause ball bearing to damage.In order to solve this technical barrier; At home in the same industry; R&D institution and science and technology in enterprise personnel use ball bearing constantly studying, explore, improve offshore vessel; Hope can design a kind of corrosion-resistant, be difficult for getting rusty, simple in structure, be applicable to the ball bearing of marine transportation hydraulic jack both sides earrings, though obtained some the progress, in practice, still exist the technological deficiency that does not overcome as yet.
Summary of the invention
The purpose of the utility model is to overcome above deficiency; Provide a kind of high-performance selflubricating two hemisphere bearings, this pair hemisphere bearing is selected advanced in the world composite material for use, and this material contains the solid lubrication particle to be formed; Have extraordinary wear resistance and self-lubricating effect, low-down thermal expansion coefficient.Guaranteed that bearing is all to have the good stable performance in the polar region or in tropical ocean environment.Distinctive oil groove design can conveniently suitably be added lubricant oil in the medium-term and long-term back of using of rugged environment, to increase the service life.The design of space mouth makes the processing in oil cylinder earrings bearing support ball hole easier, is convenient to install and maintenance.
The utility model solves the technological scheme that its technical problem adopted: contain bearing, space mouth, oil groove, main shaft, oil cylinder earrings bearing support; Bearing is a sphere, and synthetic by two hemisphere, the bearing centre position is provided with an oil groove; In two hemisphere assembling main shafts; Two hemisphere seam place mutually has the space mouth of certain distance, and Bearing Installation is in oil cylinder earrings bearing support, and bearing is rotatable 3 °～8 ° of oil cylinder earrings bearing support.
The know-why that the utility model adopts is: adopt distinctive oil groove design, be convenient to add lubricant oil in the medium-term and long-term back of using of rugged environment, prolong bearing working life.Adopt the design of space mouth, make the processing in oil cylinder earrings bearing support ball hole easier, be convenient to install.This ball bearing is made up of the composite parts and the solid lubrication particle of uniqueness, has extraordinary wear resistance.Density only is equivalent to 1/7 to 1/6 of common copper bearing, is convenient to install and maintenance.And thermal expansion coefficient is very low, in seawater, does not almost expand, and makes bearing under any working environment, have good dimensional stability.Bearing has bigger load-carrying ability and impact resistance rotatable 3 °～8 ° of oil cylinder earrings bearing support.
The utility model beneficial effect is: the two hemisphere bearings of high-performance selflubricating are made up of the composite parts and the solid lubrication particle of uniqueness; Has extraordinary wear resistance, low-down thermal expansion coefficient and extremely low density; Guaranteed that bearing is in the polar region or in tropical ocean environment good dimensional stability and rub resistance to be arranged all, be convenient to install and maintenance.Distinctive oil groove design and the design of space mouth are conveniently added lubricant oil in the medium-term and long-term back of using of rugged environment, and installation and processing is easy.
Description of drawings
Be to combine accompanying drawing and embodiment that the utility model is further described below:
Fig. 1 is the two hemisphere bearing structural representations of high-performance selflubricating;
Fig. 2 is that the two hemisphere bearings of high-performance selflubricating are used schematic representation.
In the drawings: 1 bearing, 2 space mouths, 3 oil grooves, 4 main shafts, 5 oil cylinder earrings bearing supports.
Embodiment
In Fig. 1, Fig. 2: bearing 1 is a sphere; Synthetic by two hemisphere; Bearing 1 central position is provided with an oil groove 3, and in two hemisphere assembling main shafts 4, two hemisphere seam place mutually has the space mouth 2 of certain distance; Bearing 1 is installed in 5 li of oil cylinder earrings bearing supports, and bearing 1 turns 3 °～8 ° at oil cylinder earrings bearing support 5.
The two hemisphere bearings of this high-performance selflubricating adopt distinctive oil groove 3 designs, are convenient to add lubricant oil in the medium-term and long-term back of using of rugged environment, prolong 1 working life of bearing.Adopt 2 designs of space mouth, make the processing in oil cylinder earrings bearing support 5 ball holes easier, be convenient to install.This ball bearing is made up of the composite parts and the solid lubrication particle of uniqueness, has extraordinary wear resistance.Density only is equivalent to 1/7 to 1/6 of common copper bearing, is convenient to install and maintenance.And thermal expansion coefficient is very low, in seawater, does not almost expand, and makes bearing 1 under any working environment, have good dimensional stability.Bearing 1 turns 3 °～8 ° at oil cylinder earrings bearing support 5, has bigger load-carrying ability and impact resistance.
