Abstract
The utility model relates to a multistage bearing which is composed of an inner ring, an outer ring, a plurality of middle rings, driving medium groups which have one more than the number of the middle rings, and holding frames, the number of which is same as that of the driving medium groups. The medium of the multistage bearing can be one or the arrangement and the combination of roll balls or roll columns or roll needles or fluid body (such as oil). According to the structural change of the medium, the inner ring, the outer ring and the middle ring, the multistage bearing can be a multistage rolling bearing or a multistage sliding bearing or multiple arrangement, and the multistage bearing can be a multistage centripetal bearing and can also be a multistage pushing force bearing. The utility model is characterized in that the multistage bearing is low in friction coefficient and enhances loading rotating speed.
Description
The utility model belongs to general Multistage bearings such as mechanical engineering.
At present the bearing that uses all is a single-stage, and promptly a bearing is only by an inner ring, an outer ring and be distributed in one group of driving medium between the Internal and external cycle, i.e. ball, roller, needle roller, or a kind of and retainer in the fluid (as oil).
The purpose of this utility model is to design and a kind ofly can reduces friction factor (friction factor reduces more than 20%), bears higher rotating speed, increases the service life the energy-conservation Multistage bearing of taping the latent power and increasing work efficiency.
The utility model is achieved in that Multistage bearing is for traditional bearing, the so-called multistage secondary that promptly refers to, more than three grades or three grades, it increases several centre circles and some groups of driving mediums and retainer and forms on the basis of traditional bearing.Centre circle of every increase just must increase by one group of driving medium and retainer (driving medium for fluid time make an exception).
In the Multistage bearing, can use same driving medium to make various series product, also can be the various series product that the part of multiple driving medium or use are simultaneously made.It promptly can be multistage radial bearing, also can be multistage thrust-bearing.
Because this Multistage bearing has the arranging of variability, medium, the modularity of progression, thereby this Multistage bearing can develop into miscellaneous Multistage bearing world.
Be that example further specifies now with three grades of ball bearings.
Fig. 1 is the plan view (retainer does not draw) of three grades of ball bearings.
Fig. 2 is the sectional view of three grades of ball bearings.
Fig. 3 is the plan view of the centre circle 3 of three grades of ball bearings.
Fig. 4 is the left view of the centre circle 3 of three grades of ball bearings.
The centre circle 3 of three grades of ball bearings is identical with the structure of centre circle 2.
As can be seen from Figure 1, the ball set 7 that between inner ring 1 and the centre circle 2 one group of driving medium to be arranged be ball, centre circle 2 has spherical groove with the inside and outside surface of centre circle 3, as shown in Figure 4.The outer surface of inner ring 1, the internal surface of outer ring 4 has spherical groove so that interior, in, the shape of the surface configuration driving medium contacted with it of outer ring adapts.
The transmission way of power has two kinds: promptly from inside to outside or from outside to inside.As from inside to outside approach be: external force → inner ring 1 → ball set 7 → centre circle 2 → ball set 6 → centre circle 3 → ball set 5 → outer ring 4 → externally effect.
The driving medium of Multistage bearing if adjacent what when all being fluid (as oil), then should be at the two ends of one or several centre circle design convex shoulder, in case centre circle in use comes off, in the secondary bearing shown in Fig. 5,6, be provided with convex shoulder 9 in the end of centre circle 8, for ease of installing, centre circle 8 should be formed by two at least.
Claims (4)
1, Multistage bearing, comprise inner ring 1, outer ring 4, driving medium 5 and retainer, it is characterized in that: between inside and outside circle, increased several centre circles 2,3, driving medium and retainer, centre circle of every increase just correspondingly increases by one group of driving medium and a retainer.
2, Multistage bearing according to claim 1 is characterized in that: driving medium can be a certain series in ball, roller, needle roller or the fluid (as oil), also can be several or whole arrangement wherein, the series that combines.
3, Multistage bearing according to claim 1 is characterized in that: the shape of the interior shape driving medium contacted with it of the outer surface of inner ring, outer ring adapts, and the shape that the inside and outside surface configuration of centre circle should driving medium contacted with it adapts.
4, Multistage bearing according to claim 1 is characterized in that: when adjacent multistage driving medium all is fluid (as oil), should have the two end part of a centre circle that convex shoulder is arranged in some centre circles at least.
