Description
Technical field
The utility model relates to technical field of bearings, the concrete lubricating structure that relates to a kind of sliding bearing.
Background technique
Traditional sliding bearing adopts graphite larger as the direct friction loss between lubriation material and sliding bearing and outside rotating shaft more, easily produces larger noise and vibration, affects working life and the manufacturing efficiency of bearing.For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of sliding bearing [application number: 201110208218.2], its sliding bearing axle bush insert is in plain bearing housing, sliding bearing axle sleeve outside is connected with sliding bearing axle bush inner side, I shape pin is positioned sliding bearing axle bush on plain bearing housing, end at sliding bearing axle sleeve arranges carrier, and carrier external coating one deck resin material.
Foregoing invention project organization is comparatively simple, formation friction pair can coincide inside sliding bearing axle sleeve outside and sliding bearing axle bush, and on sliding bearing axle bush, have multiple circular ports of being filled by carbon fiber composite of evenly arranging, can ensure that lubriation material forms continuous lubrication layer all the time on pivot friction surface, has improved the working life of bearing.But foregoing invention is just improved the material of axle bush, makes it more wear-resisting, although to a certain degree improve the working life of bearing, still cannot be from solving in essence this problem that is easy to wear and tear.
For this reason, people have designed the bearing that prevents inner abrasion to the sliding contact surface supplying lubricating oil between axle and the bearing of the described axle of supporting.The supply of lubricant oil is periodically carried out, and such lubricant oil is along with the rotation of axle and move about and import to the sliding contact surface between axle and sliding bearing and form thin oil film.In such sliding bearing, in the time that device stops or while startup or be subject to mobility load during from outside, described oil film partially destroys sometimes, and if spent certain service time, the phenomenon of oil film deficiency occurs due to exhausting of lubricant oil.In the time there is so local oil film cut-out or oil film deficiency, the contact between axle and sliding bearing increases, thereby according to the frictional heat being produced by this contact, seizure occurs between axle and sliding bearing, and abrasion loss further increases thus.For example, Chinese patent literature discloses a kind of sliding bearing and slide bearing assembly [application number: CN102667191A], inner peripheral surface and outer circumferential face, and the face at 100-1000kg/cm2 is depressed use, it is characterized in that, on at least one in described inner peripheral surface and described outer circumferential face, be formed with lubricant oil thesaurus, described at least one the Area Ratio in described lubricant oil thesaurus and described inner peripheral surface and described outer circumferential face is 15-60%.
Although such scheme has certain lubrication effect, in the time sliding, described lubricant oil thesaurus is to sliding contact surface supplying lubricating oil, thereby prevents the cut phenomenon of local oil film.But, said apparatus complex structure, and press on opposite and rotating speed has certain Applicable scope, and the most important thing is is not all providing effective processing mode aspect the recovery of lubricant oil and greasy dirt processing.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of lubricating structure of sliding bearing is provided; Solve the existing lubrication effect of prior art undesirable, complex structure, lubricant oil cannot reuse, the technical problem of the difficult processing of greasy dirt etc.
For achieving the above object, the utility model has adopted following technical proposal: the utility model comprises the arc oil groove that is arranged on tubular bearing shell upper inside wall, this arc oil groove is axially placed in the middle setting of bearing shell, the two ends of described arc oil groove are respectively equipped with and are positioned at bearing shell upper inside wall and symmetrically arranged oil film formation groove, described oil film forms groove and is watt type and extending axially along bearing shell, form groove bottom at each oil film and be respectively equipped with the oil storage sewage groove that the degree of depth is greater than oil film formation groove top, described arc oil groove middle part is provided with the oil hole that is positioned at bearing shell top and connects the inside and outside side of bearing shell, form the oil outlet that is respectively equipped with at least one on groove and extends to bearing shell end face at each oil film.
In the lubricating structure of above-mentioned sliding bearing, the cross section of described oil storage sewage groove is circular arc.
In the lubricating structure of above-mentioned sliding bearing, described bearing shell top outer is provided with the groove for rigidity damping assembly is set, and the upper end of described oil hole is positioned at the bottom land of groove.
In the lubricating structure of above-mentioned sliding bearing, in described groove, be provided with rigidity damping assembly, on described rigidity damping assembly, have the oil inlet hole that runs through rigidity damping assembly, described oil inlet hole and oil hole connect.
Compared with prior art, the advantage of the lubricating structure of this sliding bearing is: 1, the supply of lubricant oil becomes convenient and simple; 2, the oil film of arc oil groove and watt type forms the design of the groove bearing shell of more fitting, and has also increased lubrication effect; 3, the setting of oil storage sewage groove, becomes simply the processing of greasy dirt and the recycling of lubricant oil, has realized the object of the sustainable development of energy-conserving and environment-protective.
