Description
Technical field
The utility model belongs to mechanical casting techniques field, especially relates to a kind of bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor, when other parts produce relative movement each other on axle, bearing can supported mechanical solid of rotation, can reduce friction factor in power transmission process and retainer shaft central position is fixed.Between bearing and axle during relative movement, have grease and produce, be unfavorable for lubrication, and do not have a kind of bearing can removing grease in prior art, global design is reasonable not enough, poor practicability.
In order to improve prior art, people have carried out long-term exploration, propose various solution.Such as, Chinese patent literature discloses a kind of oil-impregnated bearing [application number: CN201420657257.X] holding grease, there is central through bore, two end face all there is the alternate spiral helicine oil trap around distribution and all corresponding with the oil trap on outer side surface connection, the diameter larger than the diameter of two-end part 0.1 of the inherent intermediate portion of central through bore, intermediate portion accounts for 5/8 of oil-impregnated bearing length.
Although such scheme to some extent solves the deficiencies in the prior art, can not scrape grease well, global design is reasonable not, poor practicability.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, the simple bearing of structure.
For achieving the above object, the utility model have employed following technical proposal: this bearing, comprise bearing body, the upper inside wall of described bearing body is provided with grease groove, one end cell wall indent of described grease groove is formed scrapes dirty groove, the other end is connected by the first arc-shaped transition limit with bearing body inwall, the described lower end of scraping dirty groove be connect with grease groove inwall scrape dirty part, described dirty groove of scraping is connected by return line with oil groove on the side interior wall being located at bearing body, the degree of depth of described grease groove reduces from centre gradually to both sides, described return line comprises some one end and scrapes the first oil return that dirty groove is connected and be in charge of the second oil return be connected with oil groove with some one end and be in charge of, the first described oil return is in charge of to be in charge of with the second oil return by pooled portion and is connected, the inlet opening end that the first described oil return is in charge of is provided with the filter screen being arranged in and scraping dirty groove, the described cell wall scraping dirty groove is provided with the mounting structure can fixing filter screen.When axle rotates relative to bearing, scrape dirty part and be beneficial to and scrape in dirty groove by grease, net filtration after filtration, unnecessary lubricant oil then enters into oil groove by return line, again plays the effect of lubrication, and global design is reasonable, and structure is simple, practical.
In above-mentioned bearing, described mounting structure comprises the mounting plate be located at and scraped on dirty groove 3 cell wall, described mounting plate and scrape the first gap being provided with between dirty groove and inserting for filter screen, described mounting plate has mounting hole, described filter screen is provided with the assembling set adapted with mounting hole, and when assembling set inserts mounting hole and after transverse shifting, filter screen is relatively fixed on and scrapes in dirty groove.Filter screen is put into mounting plate and scrape between dirty groove, then by filter screen upwardly, make assembling set be inserted in mounting hole, laterally promote assembling set again to make filter screen relative to scraping dirty groove fix to one end, simple to operate, detachably change when filter screen damages, increase the service life.
In above-mentioned bearing, described mounting hole is cross bore, described assembling set comprises the longitudinal direction can inserting cross bore and inserts plate, the end that described longitudinal direction inserts plate is provided with fixed plate, described fixed plate with longitudinally to insert plate perpendicular, and when longitudinally inserting plate insertion cross bore and transverse shifting rear fixed plate and mounting plate fix.
In above-mentioned bearing, described grease groove reduces trend from centre to the degree of depth of scraping dirty groove end and is less than grease groove from centre to the less trend of the degree of depth of the other end.
Compared with prior art, the advantage of this bearing is: first, when axle rotates relative to bearing, scrape dirty part to be beneficial to and to scrape in dirty groove by grease, net filtration after filtration, unnecessary lubricant oil then enters into oil groove by return line, again the effect of lubrication is played, global design is reasonable, and structure is simple, practical.The second, filter screen is put between mounting plate and grease groove, then by filter screen upwardly, assembling set is inserted in mounting hole, more laterally to one end promotion assembling set, filter screen is fixed relative to grease groove, simple to operate.3rd, detachably change when filter screen damages, increase the service life.
