Abstract
The present invention provides a kind of flexible bearing of adjustable clearance, and the bearing includes outer ring, inner ring, flexible retaining ring, raceway punching press circle, several steel balls, wherein the outer ring is spill, and there are two turnings；The flexibility retaining ring is two, and the bottom of described two flexibility retaining rings and wall portion match with described two turnings respectively, and its top is concave surface；The raceway punching press circle is two；The outer wall of the inner ring is provided with first annular raceway；Described two flexibility retaining rings are individually fixed in the corner of the outer ring, and the raceway punching press circle turns up respectively to be wrapped on the concave surface of the flexible punching press circle, and forms the second ring raceway；The steel ball is between the first ring raceway and the second ring raceway.Through the invention, to solve, tune gap bearing arrangement of the existing technology is complicated, is easy to the problems such as temperature rise, noise occur.
Description
Technical field
The invention belongs to bearing arrangement technical field more particularly to a kind of flexible bearings of adjustable clearance.
Background technique
Bearing is common mechanical part in industrial machinery, adjusts the one kind of gap bearing as bearing.But existing tune gap
Bearing is in the presence of structure is complicated, is easy to temperature rise, noise etc. occur.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of low noise, it is not easy to heat up, the bearing of adjustable slit.
To solve the above-mentioned problems, technical solution provided by the present invention is：
A kind of flexible bearing of adjustable clearance, the bearing includes outer ring, inner ring, flexible retaining ring, raceway punching press circle, several
Steel ball, wherein the outer ring is spill, and there are two turnings；The flexibility retaining ring is two, the bottom of described two flexibility retaining rings
Portion and wall portion match with described two turnings respectively, and its top is concave surface；The raceway punching press circle is two；The inner ring
Outer wall be provided with first annular raceway；Described two flexibility retaining rings are individually fixed in the corner of the outer ring, the raceway
Punching press circle turns up respectively to be wrapped on the concave surface of the flexible punching press circle, and forms the second ring raceway；The steel ball is located at institute
It states between the first ring raceway and the second ring raceway.
Preferably, the outer ring is drawn cup.
Preferably, the flexible retaining ring is rubber retaining ring.
Preferably, the concave surface can be irregular concave surface.
The beneficial effects of the present invention are：Product of the invention will be in bearing by the elastic element on the double raceway both sides in outer ring
The gap in portion is eliminated, while bearing also has certain spring function, and the beat that can make up shell and axis causes bearing rotary
Inclination, provides the stationarity of rotation；Product is consolidated bearing inner raceway and steel ball by the elastic element at both ends when rotation
It is fixed, it appropriate can reduce influence of the assembly vibration to product.
Detailed description of the invention
In order to describe the content of the present invention more clearly and completely, several width, which are provided below, most can illustrate the attached drawing of present inventive concept.
Certainly, provided attached drawing is intended to illustrate the concept of the present invention, and is not the whole of design scheme of the present invention, more be should not be considered as
The limitation of design content of the present invention.Under the enlightenment of provided attached drawing, made any scheme belongs to protection of the invention
Range.
Fig. 1 is the structural schematic diagram of bearing；
Fig. 2 is the A-A cross-sectional view of bearing；
Fig. 3 is the perspective view of bearing.
Specific embodiment
In order to describe the content of the present invention more clearly and completely, illustrate design of the invention With reference to embodiment.
Certainly, provided embodiment is intended to illustrate the concept of the present invention, and is not the whole of design scheme of the present invention, should less be regarded
For the limitation of design content of the present invention.Under the enlightenment of provided content, made any scheme belongs to guarantor of the invention
Protect range.
Fig. 1, shown in 2, a kind of flexible bearing of adjustable clearance, the bearing includes outer ring 1, inner ring 4, flexible retaining ring 2, rolling
Road punching press circle 3, several steel balls 5, wherein the outer ring is spill, and there are two turnings；The flexibility retaining ring is two, described
The bottom of two flexible retaining rings and wall portion match with described two turnings respectively, and its top is concave surface；The raceway punching press
Circle is two；The outer wall of the inner ring is provided with first annular raceway；Described two flexibility retaining rings are individually fixed in the outer ring
Corner, the raceway punching press circle turns up respectively to be wrapped on the concave surface of the flexible punching press circle, and forms the second annular rolling
Road；The steel ball is between the first ring raceway and the second ring raceway；The outer ring is drawn cup；The flexible gear
Circle is rubber retaining ring, and the concave surface can be irregular concave surface.
The flexible bearing of adjustable clearance of the invention, will be between Bearing inner by the elastic element on the double raceway both sides in outer ring
Gap is eliminated, while bearing also has certain spring function, and the beat that can make up shell and axis causes bearing rotary to tilt, and mentions
For the stationarity of rotation.
Product is fixed bearing inner raceway and steel ball by the elastic element at both ends when rotation, appropriate can be dropped
Low assembly vibrates the influence to product.Since elastic element pre-tightens, inner ring, the steel ball shape for being in fitting consistent with outer ring of product
State, steel ball can be carried uniformly.The inner ring and steel ball and outer ring raceway of bearing are not contacted with outer housing, are connect by elastic element
Touching, can play the role of insulation, the galvanic corrosion phenomenon for preventing assembly to be powered.The inner ring of bearing is matched with axis/outer ring and shell interference
It closes, inner ring and outer ring deflection caused by magnitude of interference will not cause very big influence, internal elastic element to the torque of bearing
Play certain resigning buffer function.
