Description
Technical field
The utility model relates to technical field of bearings, is specifically full-complement cylinder roller bearing.
Background technique
Full-complement cylinder roller bearing designs to bear heavy load.Under same width, this bearing is compared with traditional band retainer bearing, and have high bearing capacity, radial cross section is little, can save space, but rotating speed is relatively low; It is widely applied on big machinery.
Existing full-complement cylinder roller bearing main structure is: include bearing inner race, bearing outer ring and cylindrical roller, the outer peripheral surface of bearing inner race is provided with lower raceway, the inner peripheral surface of bearing outer ring is provided with raceway, the axial outer end of bearing inner race and bearing outer ring has rib, namely the bearing end positions of upper and lower raceway has described rib, be two rib groove raceway, rib is formed and remains in upper and lower raceway to the spacing of cylindrical roller, grinding undercut is provided with, expediently to descend being processed to form of raceway in the joint of upper and lower raceway and rib.
For full-complement cylinder roller bearing, its existing architecture advances, be embodied in two aspects, one is that (traditional roller bearing is open design for bearing dust-proof, namely the working zone of bearing directly contacts with external environment, when causing bearing working, introduced contaminants can not effectively be stopped, enter in roller bearing raceway, bearing is finally caused to shift to an earlier date fatigue failure, seriously reduce the working life of bearing), (bearing enclose adopts rib design to the operating reliability of another bearing, realize the maintenance of cylindrical roller, and ensure the axial carrying capacity of bearing, but the design of rib, make the processing inconvenience of bearing, dimension control difficulty, assemble difficulty simultaneously, and cause the stability of bearing operation not high).
For improving the sealing of full-complement cylinder roller bearing, existing usual way has, and arranges sealing configuration and realize between the inside and outside circle of bearing, but its to there is structure not compact, the problem of assembling inconvenience.
Consider the processing of full dress roller bearing, assembling, the compactedness of structure and bearing reliability of operation for this reason, existing rib on bearing inner race to be removed, rely on back-up ring to replace; Existing part completely fills roller bearing, and some adopts removal bearing inner race rib on one side, or remove rib on bearing inner race two ends, rely on two back-up ring to realize (if the patent No. is " full-complement cylinder roller bearing " disclosed in the patent documentation of 201020298600.8 (Authorization Notice No. is: CN 201747767 U)).
But existing full-complement cylinder roller bearing still can not well realize for the structure fusion of above-mentioned two kinds of improvement in performance, still there is machining accuracy and control inconvenience, the defect that structure is not compact and assembling is inconvenient, affects the run stability of bearing.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of good airproof performance, easy to process, and machining accuracy controllability is good, compact structure, the easy to assembly and stable two ring type full-complement cylinder roller bearings that operate.
For achieving the above object, the utility model provides following technological scheme: a kind of two ring type full-complement cylinder roller bearing, include bearing inner race, bearing outer ring and cylindrical roller, the outer peripheral surface of described bearing inner race is provided with lower raceway, described lower raceway is plane raceway, the axial two ends of bearing inner race are respectively equipped with left loose rib and right loose rib, the inner peripheral surface of described bearing outer ring is provided with raceway, described cylindrical roller is bearing in, in lower raceway, its spy is: on described bearing outer ring, upper raceway is also plane raceway, the inner peripheral surface of described bearing outer ring is positioned at the axial end positions of raceway and offers back-up ring mounting groove, back-up ring mounting groove faces and is connected to described upper raceway, left, the radial inner end of right loose rib extends to bearing outer ring and is inlaid in back-up ring mounting groove.
By adopting technique scheme, also plane raceway is adopted to design raceway upper on bearing outer ring, upper raceway on bearing outer ring is facilitated to be processed to form, and realize the size Control to upper raceway by the dimensional accuracy controlling back-up ring mounting groove, size Control precision is accurately more convenient, simultaneously compact structure after bearing assemble, left and right loose rib, bearing outer ring and bearing inner race easy to assembly, thus improve the run stability of bearing; And left and right loose rib plays dust cover effect, achieve the sealing to Bearing inner, reach good sealing effect and realize sealability and run stability advantage simultaneously.
The utility model is set to further: described left loose rib and right loose rib include ring body, the radial outer peripheral surface of ring body is evenly provided with gear piece portion, location at equal intervals, gap-forming locating slot between gear piece portion, location, described back-up ring mounting groove is made up of the some short slots be arranged at equal intervals on bearing outer ring axial end, short slot quantity is identical with gear piece portion, location quantity, positioning convex is formed between each short slot, gear piece portion, location adaptation is assemblied in short slot, and positioning convex adaptation is inlaid in locating slot.
By adopting technique scheme, the orientation assemble of left and right back-up ring is solid and reliable.
The utility model is set to further: the radial end face of described short slot is the plane of inclination that axial outer end is low, axial inner ends is high.
By adopting technique scheme, the assembling of left and right back-up ring is more convenient and solid and reliable.
Below in conjunction with accompanying drawing, the utility model is further described.
