Description
Technical field
The present invention is relevant with bearing, refers to a kind of staggered form roller bearing especially.
Background technique
Staggered form roller bearing arranges a kind of bearing of roller between inner ring and outer shroud staggered each other, and make staggered form roller bearing can bear radial load, axial load and moment load simultaneously.Compared with the bearing of general type, staggered form roller bearing is specially adapted to the occasion requiring high rigidity and running accuracy, as machine tool and manipulator ....Look back existing staggered form roller bearing as Japanese Unexamined Patent Publication 2000----65080, JP 2000----170754, JP 2002-13540 and JP 2005-180578 patent, all that the mounting hole being used for assembling roller is designed to the track rolled as Vertical direction designs, thus, make each bearing can produce two plane of trajectory orbital simultaneously damaged because of the setting of mounting hole, low when also causing bearing load ability comparatively to only have a plane of trajectory orbital damaged.
In addition, the filling member being used for filling mounting hole in the ideal case should be matched with plane of trajectory orbital, and allow plane of trajectory orbital keep smooth.Produce because machining error makes filling member and plane of trajectory orbital still have irregular situation.If from existing staggered form roller bearing, filling member must have the design of supplying two plane of trajectory orbital, easy generation filling member with the alignment of one of them plane of trajectory orbital, and another plane of trajectory orbital is still irregular situation, and namely the irregular chance of plane of trajectory orbital is high.Besides the filling member of above-mentioned intersection bearing, need machning v grooves Composite Double curved surface to come matching track face, its processing cost comparatively makes the high of single curved surface.
Summary of the invention
Main purpose of the present invention is to provide a kind of staggered form roller bearing, and it produces the breakage of a plane of trajectory orbital, the height that its load carrying capacity is next compared with prior art.
Of the present invention time an object is to provide a kind of staggered form roller bearing, and its fabricating cost is lower, and the irregular chance of track is also lower.
Edge is, in order to reach aforementioned object, according to a kind of staggered form roller bearing provided by the present invention, include an inner ring, have one first anchor ring, this inner ring forms one first rolling groove on this first anchor ring, and this first rolling groove has complete first plane of trajectory orbital and the second plane of trajectory orbital; One outer shroud, be set in outside this inner ring, this outer shroud has one second anchor ring and a mounting hole, this outer shroud forms one second rolling groove on this second anchor ring, this second rolling groove is to arranging by the first rolling groove, this second rolling groove has one the 3rd plane of trajectory orbital and one the 4th plane of trajectory orbital, and jointly forms a containing space with this first plane of trajectory orbital and this second plane of trajectory orbital; This mounting hole is through 3rd plane of trajectory orbital or the 4th plane of trajectory orbital, and forms a breakage spot in the 3rd plane of trajectory orbital or the 4th plane of trajectory orbital, and the contact area maintaining another plane of trajectory orbital and roller is complete and not damaged; Multiple roller, is installed with respectively in this containing space; And a filling member, be arranged in this mounting hole and fill this breakage spot.
In addition, under identical spirit, the present invention also provides a kind of staggered form roller bearing, include an inner ring, have one first anchor ring and a mounting hole, this inner ring forms one first rolling groove on this first anchor ring, and this first rolling groove has one first plane of trajectory orbital and one second plane of trajectory orbital; This mounting hole is this first plane of trajectory orbital through or this second plane of trajectory orbital, and forms a breakage spot in this first plane of trajectory orbital or this second plane of trajectory orbital, and the contact area maintaining an another plane of trajectory orbital and roller is complete and not damaged; One outer shroud, be set in outside this inner ring, this outer shroud has one second anchor ring, this outer shroud forms one second rolling groove on this second anchor ring, this second rolling groove is to arranging by the first rolling groove, this second rolling groove has complete the 3rd plane of trajectory orbital and the 4th plane of trajectory orbital, and jointly forms a containing space with this first plane of trajectory orbital and this second plane of trajectory orbital; Multiple roller, is installed with respectively in this containing space; And a filling member, be arranged in this mounting hole and fill this breakage spot.
