Abstract
A roller bearing comprising an inner and an outer ring in concentrical arrangement, a series of roller elements being arranged in the space between said rings and being in contact with raceways provided in said rings. The bearing is characterized in that said raceways are provided with parallel grooves, each one of said grooves being arranged in the plane of rotation of said rings and extending along the entire envelope surface, and in mutual correspondence to said inner and outer rings and being arranged for mating interaction with protruding flanges of said roller elements corresponding to said grooves, said protruding flanges extending along the entire envelope surface of said roller elements.
Description
The present invention relates to a kind of roller bearing, this bearing comprises the outer ring and the inner ring of arranged concentric, and one group of contacted rolling element of raceway that places between described outer ring and the inner ring and provided with described outer ring and inner ring.
In some application, bearing is subjected to the restriction of depth of section, and need bear higher axial load and radial load.Adopted the mode of needle bearing and ball bearing combination to solve this problem in the past.Needle bearing is used for bearing most radial load and ball bearing is used for bearing axial load.But the shortcoming that this settling mode exists is that expense is very expensive, and forces the artificer must limit the axial load of bearing and/or the depth of section that increases bearing improves the bearing capacity of ball bearing.
U.S. Pat 2,251,555 have disclosed a kind of no friction roll bearing, its concrete structure is: comprise an elongated cylindrical body, a plurality of axial each intervals are arranged and the V-shaped groove of extending circumferentially on cylindrical circumferential surface, periphery between the V-shaped groove is that described cylindrical two ends are connected with the starting point of V-shaped groove along all crooked contoured surface of described cylindrical body circumferential and axial; Near the inner edge of periphery one end, promptly a back-up ring is set in end near the described roller of circumference.The foregoing invention and a main distinction of the present invention are U.S. Pat 2,251, and 555 disclosed bearings can not bear axial load.The main purpose of foregoing invention is to reduce friction by the area of contact of reducing friction.Can not bear axial load and relate to bearing.
U.S. Pat 2,266,888 have disclosed a kind of antifriction bearing.This bearing comprises an axle journal that has annular corrugated groove in the whole length range of bearing area; One has equally with the corresponding damascene trench of axle journal groove in the whole length range of supporting plane, and the shell that matches with axle journal; And one group of roller that between two supporting planes, is intervally installed, be distributed with on its whole loaded length to axle journal and shell supporting plane on the similar annular groove of groove, and be complementary with both and bear load, described annular groove on roller, axle journal and shell has the convex side, between two relative annular grooves, the top of described annular groove is one with the midpoint of bottom and contacts the restricted area.This bearing also comprises the device that can make roller keep each interval, and this device comprises the gear of being located at the every end of roller and is located on axle journal and the shell respectively and the gear that is meshed with the gear of the every end of roller.Resemble U. S. Patent 2,251,555 is the same, and the main distinction of the present invention and U. S. Patent 2,266,888 is that the disclosed bearing of above-mentioned patent is not used in and bears axial load.The main purpose of foregoing invention provides the bearing of the resistance of reducing friction.In foregoing invention, do not relate to bearing yet and whether can bear axial load.
The invention is characterized in: the seat ring raceway of bearing is provided with parallel each other groove, described each groove all is positioned on the surface of revolution of described inner ring and outer ring, on whole envelope circumferential surface, extend, and it is corresponding mutually with described inner ring and outer ring, and be meshing with each other with the flange of the corresponding described rolling element of described groove, described flange extends on the whole circumference surface of described rolling element.
Fig. 1 is the partial sectional view of the optimum implementation of roller bearing of the present invention.
In roller bearing partial sectional view shown in Figure 1, bearing 1 is made of bearing outer ring and 2,3 and one groups of rolling elements 4 of inner ring of arranged concentric.In Fig. 1, only shown one of them rolling element.Rolling element 4 is arranged between inner ring and the outer ring 2,3, and contacts with inner ring and outer ring 2,3 raceways that provided.Seat ring is provided with parallel each other groove 5,6.Every groove 5,6 is arranged on the surface of revolution of inner ring and outer ring 2,3, and extends along the whole circumference surface.Groove 5,6 and described inner ring and outer ring 2,3 are corresponding mutually, and the flange 7 of corresponding described rolling element 4 is meshing with each other with it.Flange 7 extends along the whole circumference surface of rolling element 4.
In another embodiment, there is a slight distance △ between the groove 5,6 of two any disposed adjacent on inner ring and the outer ring 2,3 and between the flange 7 in two disposed adjacent of rolling element 4, so that produce certain inside preload on the bearing 1.The purpose of this preload reduces axially and radial clearance exactly.A kind of method that produces this slight distance △ be inner ring and outer ring 2,3 both one of or both surface of revolution at least one packing element of configuration, the quantity of this packing element and thickness can be determined according to desired preload or use condition.Another method that produces this slight distance △ is at least one rolling element 4 at least one packing element to be set.
In addition, the shape of the groove 5,6 on inner ring and the outer ring 2,3 is by predetermined radii R
wDecision, its shape is corresponding with the shape of the flange 7 of rolling element 4.The shape of the flange 7 of at least one rolling element 4 is by predetermined radii R
wDetermine.The profile size that should be noted that flange 7 needn't be identical, that is to say, the flange at the flange of an end of rolling element 4 and rolling element 4 middle parts needn't be of similar shape.Certainly, this just requires corresponding groove to do corresponding the adjustment.But for practical purposes, all predetermined radiis all are taken as same size usually.Another alternative embodiment of the present invention is that described bearing comprises that also one is used for guiding and separates rolling element 4 and the retainer that enough lubricates can be provided.Lubricating grease preferably places this retainer.
