Abstract
The utility model provides a bearing with a self-aligning function. The bearing comprises an outer race (1), an inner race (2), rolling bodies (3) and a retainer (4), wherein the rolling bodies (3) can be put on the retainer (4) in a rolling manner and can be movably arranged between the outer race (1) and the inner race (2) together with the retainer (4); and the inner race (2) can be put in the outer race (1) in a rolling manner. The bearing is characterized in that the outer race (2) comprises an outer ring (21) and an inner ring (22); the inner surface of the outer ring (21) is a concave spherical surface (211) and the outer surface of the inner ring (22) is a convex spherical surface (221); or the inner surface of the outer ring (21) is a convex spherical surface and the outer surface of the inner ring (22) is a concave spherical surface; and the inner ring (22) and the outer ring (21) can be mutually arranged asway along the axis. The bearing has the advantages that the bearing can carry out self-aligning so that the bearing operates more stably, thus prolonging the service life.
Description
Technical field
The utility model relates to a kind of bearing and makes the field, especially refers to a kind of bearing of energy aligning.
Background technique
Can produce vibration during machine works, the mechanical vibration meeting makes the bearing in the machine produce eccentric phenomenon, not only affects the life-span of bearing, more affects the normal operation of machine.Existing a kind of patent No. is that the Chinese utility model patent that the CN201120068405.0 name is called " adjusting center bearing " discloses a kind of adjusting center bearing, comprises inner ring, supporting frame, outer ring and rolling element, also comprises the elastic sleeve that is set on the described outer ring.The adjusting center bearing that the utility model embodiment provides arranges elastic sleeve on the basis of existing bearing can realize aligning, need not between inside and outside circle and rolling element, the gap to be set, namely need not each accessory of bearing is carried out special processing, reduced manufacture difficulty and the cost of adjusting center bearing.Simultaneously, the adjusting center bearing that the utility model embodiment provides adopts the flexible realization aligning of elastic sleeve, because the flexible compensation effect of elastic sleeve, so that each accessory is in conjunction with more stable, gap etc. can not occur, improve the stability of adjusting center bearing work operation.But its complex structure, and bearing rotates and can produce heat, thus can affect the performance of elastic sleeve, so its structure is further improved.
The model utility content
Technical problem to be solved in the utility model is that a kind of bearing that designs a kind of energy aligning of ingenious, simple in structure and energy aligning is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that adopts: the bearing of instinct aligning, comprise the outer ring, inner ring, rolling element and retainer, described rolling physical efficiency rollably places on the retainer, and and retainer can place actively between outer ring and the inner ring together, described inner ring can rollably place the outer ring, it is characterized in that: described inner ring comprises outer shroud and interior ring, the internal surface of described outer shroud is concave spherical surface, the outer surface of described interior ring is protruding sphere, or, the internal surface of described outer shroud is protruding sphere, and the outer surface concave spherical surface of described interior ring can be set together mutually along axis oscillating ground between described interior ring and the outer shroud.
As improvement, described interior ring outer surface is provided with for the groove that stores lubricant oil.
As improvement, between described outer ring and the inner ring dust cover is arranged.
As improvement, described rolling element is ball.
Compared with prior art, the utility model adopts described inner ring to comprise outer shroud and interior ring, the internal surface of described outer shroud is concave spherical surface, the outer surface of described interior ring is protruding sphere, or, the internal surface of described outer shroud is protruding sphere, and the outer surface concave spherical surface of described interior ring can be set together mutually along axis oscillating ground between described interior ring and the outer shroud.Its advantage is, can mutually be set together along axis oscillating ground between described interior ring and the outer shroud, plays the effect of aligning, and the axis of outer ring and inner ring is remained on the same straight line, makes the bearing operation more stable, thus the working life of improving bearing.

Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
Fig. 1 is to the bearing of the energy aligning of present embodiment shown in Figure 4, comprise outer ring 1, inner ring 2, rolling element 3 and retainer 4, described rolling element 3 is ball, described rolling element 3 can rollably place on the retainer 4, and and retainer 4 can place actively together between outer ring 1 and the inner ring 2, described inner ring center has the through hole 23 suitable with axle 6, described inner ring 2 can rollably place outer ring 1, described inner ring 2 comprises outer shroud 21 and interior ring 22, the internal surface of described outer shroud 21 is concave spherical surface 211, the outer surface of described interior ring 22 is protruding sphere 221, can mutually be set together along axis oscillating ground between described interior ring 22 and the outer shroud 21, described interior ring 22 outer surfaces are provided with for the groove 222 that stores lubricant oil, between described outer ring 1 and the inner ring 2 dust cover 5 are arranged.When bearing is in service when eccentric phenomenon occurs, because interior ring 22 can be along axis oscillating in outer shroud 21 and self-aligning, thereby improves the stability of bearing operation, thereby improve the life-span of bearing.This bearing can extensively meet the tendency in vibrating machine and run up mechanically.
Claims (4)
1. the bearing of an energy aligning, comprise outer ring (1), inner ring (2), rolling element (3) and retainer (4), described rolling element (3) can rollably place on the retainer (4), and and retainer (4) can place actively together between outer ring (1) and the inner ring (2), described inner ring (2) can rollably place outer ring (1), it is characterized in that: described inner ring (2) comprises outer shroud (21) and interior ring (22), the internal surface of described outer shroud (21) is concave spherical surface (211), the outer surface of described interior ring (22) is protruding sphere (221), or, the internal surface of described outer shroud (21) is protruding sphere, the outer surface concave spherical surface of described interior ring (22) can be set together mutually along axis oscillating ground between described interior ring (22) and the outer shroud (21).
