Abstract
The utility model provides an external guiding solid cage of an aligning roller bearing for a vibrating machine. The external guiding solid cage comprises two outer guiding double-half-solid cages (3) opposite to each other; the contacted end surfaces of the two outer guiding double-half-solid cages (3) are provided with a plurality of oil slots I (5) distributed along circumference, and the outer spherical surfaces vertical to the contacted end surfaces of the two guiding double-half-solid cages (3) are provided with a plurality of oil slots II (6) distributed along circumference; the outer circular surfaces of the contacted end surfaces of the guiding double-half-solid cages (3) are provided with slopes (4); and the outer radial surfaces of the two guiding double-half-solid cages (3) are spherical arc surfaces. The external guiding solid cage disclosed by the utility model is free from impact, caused by load, on the conventional cage of the aligning roller bearing for the vibration machine, which bears rotation acceleration and linear acceleration, so that the service life of the cage is prolonged, and further, the service life of the aligning roller bearing of the vibrating machine is prolonged.
Description
Technical field
The utility model relates to a kind of retainer, is specifically related to a kind of vibrating machine and guides solid cage outward with selfaligning roller bearing.
Background technique
In the application of vibrating machine, the early failue of retainer accounts for significant proportion in the early failue of bearing.Because in the application of vibrating machine; Produce rotational acceleration and linear acceleration between the roller of bearing and the retainer; Retainer need bear the rotation load that the rotation of unloading roller causes when bearing rotation acceleration, when bearing straight line load, need bear the load of knocking of unloading roller.The selfaligning roller bearing that is used for this operating mode need support than general standard rolling bearing and receive the ability of acceleration high.This has also improved the designing requirement of retainer greatly.
The model utility content
For solving the problems of the technologies described above, the purpose of the utility model is to propose a kind of vibrating machine to guide solid cage outward with selfaligning roller bearing.
The utility model adopts following technological scheme for accomplishing the foregoing invention task:
A kind of vibrating machine guides solid cage outward with selfaligning roller bearing, and described selfaligning roller bearing guides solid cage to comprise two half solid cages of two outer guiding that are oppositely arranged outward, and has the gap between two two half solid cages of outer guiding; Outside two, all have a plurality of oil groove I along circle distribution on the two contacted end faces of half solid cage of guiding, guiding pair half solid cages contact and have a plurality of oil groove II along circle distribution on the outer spherical surface of end face perpendicular to two outside; Two half solid cages of guiding contact and all have in order to increase the slope of lubrication effect on the periphery of end face outside two; The outer diametric plane of said outer guiding solid cage is a spherical cambered surface, and guiding the minimum diameter place of the outer diametric plane of solid cage outward is the plane, and the maximum value of length H that guides the outer diametric plane of solid cage outward is less than bearing outer ring rib internal diameter.
A kind of vibrating machine that the utility model proposes guides solid cage outward with selfaligning roller bearing; Adopt technique scheme preferably resolve vibrating machine with the selfaligning roller bearing retainer when bearing rotation acceleration and linear acceleration suffered load to the impact of retainer; Prolonged retainer working life, thereby improved the life-span of vibrating machine with selfaligning roller bearing.

Among the figure: 1, outer ring, 2, inner ring, 3, two half solid cages of outer guiding, 4, the slope, 5, the oil groove I, 6, the oil groove II.
Embodiment
As shown in Figure 1; And with reference to Fig. 2, Fig. 3; A kind of vibrating machine guides solid cage outward with selfaligning roller bearing; Described selfaligning roller bearing guides solid cage to comprise two half solid cages 3 of two outer guiding that are oppositely arranged outward, and has the gap between two two half solid cages 3 of outer guiding; Outside two, all have a plurality of oil groove I 5 along circle distribution on the two contacted end faces of half solid cage of guiding, guiding pair half solid cages contact and have a plurality of oil groove II 6 along circle distribution on the outer spherical surface of end face perpendicular to two outside; Two half solid cages of guiding contact and all have on the periphery of end face in order to increasing the slope 4 of lubrication effect outside two, the width h angle [alpha] on slope 4, and its value is fixed according to the retainer size; The outer diametric plane of two half solid cages of said outer guiding is a spherical cambered surface; In conjunction with Fig. 3; The minimum diameter place of the outer diametric plane of two half solid cages of outer guiding is the plane, and the length H maximum value of the outer diametric plane of two half solid cages of outer guiding is less than bearing outer ring rib internal diameter, and specific practice diametric(al) of diametric plane outside retainer is cut the top; Assurance is cut back, top H value less than bearing outer ring rib internal diameter, for the ease of the assembling of two half solid cages of outer guiding.
Selfaligning roller bearing guides retainer outward in use; Adopt and bearing outside raceway guidance mode; The retainer external diameter is a spherical cambered surface, after assembling outside two between the two half solid cage end faces of guiding the gap be 2s, sphere diameter SR is that bearing outside raceway diameter deducts two times guide clearance; Its centre of sphere is at bearing symmetry center place, so sphere center position is apart from retainer end face s.
